SUMMARY
The plant phytochemicals (mainly the secondary metabolites) can cause different types of toxicosis in our livestock and companion animals. In such cases (or
in case of a suspicion) the chemical composition is very important. The rapid,
simple demonstration (or exclusion) of a group of bioactive molecules can basically help the veterinarian’s work. The present publication would like to give
a methodical guide for the veterinarians. Our publication summarises shortly
the affected active compounds and gives methodical descriptions, documented
with photos. The list of required chemicals and laboratory instruments is very
simple; the number of specific reagents is low. Our work is based on the simple
production of a plant extract (1 g plant/20 ml extractant) and demonstrates
the following metabolites: cyanogenic glycosides, coumarins, tannins, cardiac
glycosides, saponins, alkaloids and the nitrate ion. The HCN was liberated with
H2SO4 from plants in a closed tube and a reddish colour was formed on a filter
paper strip. Coumarins produce a yellow colour under strongly alkaline conditions; the tannins can react with FeCl3 molecules forming a bluish-blackish precipitation. Demonstration of cardiac glycosides is possible by Keller-Kiliani test,
whereas a brown-brownish ring is formed at the interface of acetic acid-FeCl3
and of H2SO4. A stable foam layer, produced by shaking, can indicate the saponins. For the detection of alkaloids different reactions were used (including the
orange-yellow precipitation by Dragendorff reagent, the bluish-purple colour by
PDAB reagent and the brownish ring at the interface by Keller reaction). Nitrate
ions can produce a yellow colour with diphenylamine on filtrate paper, induced
by UV radiation.
The methods were tested by samples of some frequent plant species, containing the affected metabolites. The presented methodical list can be developed
according to possibilities and requirements of colleagues. We hope that the
present publication can be useful for the veterinarians.

SUMMARY
Background: Lice are common ectoparasites of birds, completing their entire
life cycle in the plumage. Transmission – in most cases – requires physical contact between hosts. Lice may benefit from choosing host individuals with better
survival prospects and dispersal chances. Bodily contacts between parents and
offsprings provide a good opportunity for host selection. The Common Kestrel
is a widespread, small-bodied raptor of the Palearctic region, with well-known
breeding biology and ectoparasite fauna, making it suitable to study the ecological correlates of vertical transmission of lice.
Objectives: The aim of our study was to investigate how the sex, maturity and
clutch size of Common Kestrel nestlings affect the abundance of their lice.
Materials and Methods: Field work was carried out in Körös-Maros National
Park Directorate (Hungary). The ectoparasites were collected from nestlings (n
= 54) with dust-ruffling. The effect of the host’s sex, wing length and clutch
size on the abundance of their lice was analysed using negative binomial mixed
models.
Results and Discussion: In case of Colpocephalum subzerafae, none of the
investigated variables had a significant effect. Contrarily, clutch size had a significant effect on Degeeriella rufa abundance. In small clutches (3–4 nestlings)
the mean abundance of D. rufa (15.5 95% C.I.: 8–30) is 3.7 times higher, than in
large (5–6 nestlings) clutches (4.2 95% C.I.: 2.3–7.4). We discuss two non-exclusive explanations of this pattern. First, parental quality is known to affect
the clutch size. If low quality parents are also more heavily infested with lice,
this could explain the higher louse load of their nestlings. Alternatively, according to the dilution hypothesis, long life-cycle ectoparasites (such as lice), that
are incapable to significantly raise their subpopulation size till the fledging of
the chicks, disperse among the nestlings, resulting in lower per nestling louse
counts in larger clutches. According to our results both the breeding parameters
and the quality of the parents may affect their offsprings’ ectoparasite load.

SUMMARY
Background: The petrosal bone is one of the smallest and most complex
among the bones of the equine skull. Its irregular surface, several projections
and channels, and hidden inner structures make its visualization challenging.
Textbooks usually show this bone on different drawings and photographs, where
the structures’ relationship and their spatial organization cannot be properly
understood.
Objectives: We wanted to create high-resolution surface models of certain
petrosal bone structures in order to study them separately or in connection with
the original one.
Materials and methods: First we captured photos from a skull and its left petrosal bone. The isolated bone was scanned with a microfocus CT (FOV: 1024x1024,
size of a voxel: 0.06 x 0.06 x 0.06 mm) and DICOM images were exported. Image
volume was analysed with FEI Amira 6.0 for LifeSciences software; during segmentation individually labelled fields were generated to the following structures:
surface model of the petrosal bone, malleus, incus, os lenticulare, stapes, inner
ear and the channel of the facial nerve. 3-dimensional models were made from
the label fields, and after refinement STL (stereolithography) models were made.
Results and discussion: Changing the opacity of the surface models gave
a unique possibility to compare the inner structure of the same bone seen on
photographs and on the 3D-model in different aspects. Enlarging and labelling
the inner ear and the auditory ossicles were also performed. In order to show the
outer and the inner structure more interactively, three short video animations
were created which present the outer aspects, the middle ear cavity, the inner
ear and the channel of the facial nerve (like a virtual endoscopy). Finally, the STL model of the auditory ossicles associated with the inner ear was 3D-printed and
colorized according to the surface models. In conclusion, the 3D-visualization
(modelling, augmented and virtual reality, 3D-printing) can be an immense aid
not only in the educational, but also in clinical and research fields.

SUMMARY
Background: Semen characteristics in frequently collected samples after insertion of a Suprelorin® 4.7 mg (Virbac, France) implant have not been reported yet.
Objectives: to determine the effects of Suprelorin® 4.7 mg on the quality of
semen collected twice weekly, and on metabolic function and health by body
weight (BW) changes and serum biochemical (glucose, triglycerides, ALT, AP,
BUN, creatinine, total protein, albumin, albumin/globulin ratio, electrolytes) and
haematology analysis.
Materials and Methods: Five adult healthy male Beagles (31-46 months old,
10.4-13.9 kg) housed together and fed the same ration throughout the study
were implanted subcutaneously with 4.7 mg Suprelorin® (d0). Semen was collected twice weekly. DNA fragmentation index (% DFI) was determined with
Sperm Chromatin Structure Assay (SCSATM). BW measurements and blood sampling were performed on d0, d21, and biweekly until d112. Data was analysed with
general linear model with repeated measures.
Results and Discussion: BW was stable and haematology and biochemical
parameters remained in the normal range. In 4 dogs semen could be collected
until d10 and until d17 in the last dog. No changes in ejaculate volume, sperm
concentration, total number of spermatozoa, progressive motility, morphology
and % DFI (1.33-4.50% frozen-thawed 0 h, 1.49-6.66% frozen-thawed after 3 h
incubation at 38 °C) were detected (P≥0.112).. As semen quality was not significantly influenced, matings may result in viable offspring until aspermia occurs.
Under controlled feeding conditions, 4.7 mg Suprelorin® administration does not
result in BW changes and in any alterations of blood parameters.

SUMMARY
Background: The management of the transition period is of utmost importance for profitable dairy production, because the risk of diseases with potentially large economic effect is high.
Objectives: The aim of this study was to quantify the effect of postpartum
uterine diseases on the major reproductive parameters, and to estimate the
resulting economic loss.
Materials and Methods: The data of 3,660 calving events that occurred in
2016 and 2017 on five large-scale Hungarian Holstein-Friesian farms were analysed. Information regarding uterine treatments, retained placenta and inflammatory uterine diseases were gathered. The major reproductive parameters (i.e.
calving to conception interval – CCI, services per conception – SPC, and first
service conception risk – CR1) were calculated based on cow-level data. Statistical analyses were performed by using linear and logistic regression, and Dunnett-test. Losses due to open days, excess semen use and drug cost were taken
into account in the economic calculations (1 EUR = 320 HUF).
Results and Discussion: Uterine treatments were performed after 42.68% of the
calvings, of which 13.28% were done due to retained placenta, and 29,40% due to
uterine inflammation. Uterine treatments and retained placenta were more likely in
multiparous cows (odds ratio: 1.22 and 2.05, p = 0.0098 and p < 0.0001, respectively).
Retained placenta and uterine inflammations increased CCI by 2.7 and 28.3 days, SPC
by 0.9 and 2.2, and reduced CR1 by 4.9 and 4.0 percentage points, respectively. The
economic loss due to retained placenta amounted to 38.8 EUR per case, of which
treatment cost had the largest share (46.4%). Uterine inflammations caused 122.8
EUR loss per case, with increased number of days open responsible for 57.6% of this
loss.

SUMMARY
Background: Liquid paraffin is a widely used material worldwide for decades in
the treatment of large colon impaction in horses. The efficacy of this treatment
option has not been proved by clinical trials in horses. Conversely, there are several reports about the use of liquid paraffin in children, in which this material
has proved efficient in the control of idiopathic constipation. On the other hand,
there are no studies about efficiency in small animals, except one case report.
Objectives: The aim of the current study was to review published data and
present a retrospective case series of equine large colon impaction treated with
liquid paraffin at the Department and Clinic of Equine Medicine, University of
Veterinary Medicine Budapest, between 2015 and 2017.
Materials and Methods: Forty-nine adult horses met the inclusion criteria: all
animals had rectally palpable large colon impaction at admission. Horses were
divided in two groups, the first group was treated with magnesium sulphate and
a mixture of different salts (NaCl, KCl and NaHCO3
) (salt group), and the second
one received liquid paraffin beside the aforementioned salts (oil-salt group).
Number and duration of treatments, and the amount of administered laxatives
were recorded.
Results and Discussion: Duration of hospitalisation in each group were compared: the average (mean) time spent at the clinic in the salt group was 3.25
days, and in the oil-salt group was 3.34 days.
In this study population we found that there was no significant difference in efficacy of the treatment between the two groups (p = 0.86). Average (mean) hospitalisation period in the oil-salt group was slightly longer, compared to that of the
salt group, which may lead us to the conclusion that liquid paraffin could even
slow the transit time. In the light of our results, liquid paraffin did not accelerate
disimpaction of the large colon in the examined horses.

SUMMARY
As every university, the University of Veterinary Medicine Budapest must keep
up with the rapidly changing generations of students, and at the same time,
keep the high standards and old traditions in order to train highly-qualified professionals. To tackle the situation, firstly, we have to understand the digital age,
and the new generations entering the campus.
The digital age has brought many interesting and useful novelties. These novelties, on one hand, can distract students as they tend to lose focus on long
lectures, but on the other hand, they can be used by the lecturer to engage
students and improve knowledge transfer. Nowadays, digitally enhanced lectures mean a lot more than using Power point or Prezi presentations: we can
interact with the students sitting in the rows by asking short questions that
they answer on their phones, or instead of forbidding the use of smart devices,
we can encourage them to visit trusted websites during the lecture to look up
important information.
Instead of avoiding and denying the changes brought by the digital age, it seems
much more fruitful to turn those innovations, and use them on our sides. For
example, a group of vets and vet-educators realized the fact that the new generations spend a lot of time on social media and decided to develop a website
for professionals where vets, veterinary educators and veterinary students can
interact online in a virtual framework (Novice project funded by the European
Union).
In the first part of the article, the authors will sum up how the lectures have
changed due to the influence of the digital technologies. In the second part, 2
EU projects are going to be described that helped the UVMB to enter the digital age: the Novice project - building a social media for veterinarians and vet
students; and the VetVIP project - using virtual patient to teach basic subjects
(physiology and biochemistry).

SUMMARY
In the review the authors summarize the damage of the ectoparasites of honey
bee, the problems they face when defending against it and describe viral infections in details. Since 2006, beekeepers have reported the mysterious disappearance of bees worldwide, which is based on initial research into pesticide,
environmental hunger due to environmental stress and viruses. However, it has
now become clear that partially the varroa mite is responsible for the Colony Collapse Disorder. Nowadays, the greatest economic damage was caused by varroa
mite. The defence against varroa mite has several weaknesses, which complicates the efficiency of treatments. The beekeeping practice of the last years
showed that due to the one-sided use of chemicals appearance of new resistant
variants needs to be considered. The resistance can be developed against any
active ingredients. The high bee density of our country increases the rate of
mite infestation and reinfection. Beekeepers with non-sufficient professional
knowledge do not protect their honeybee colonies with a single treatment,
furthermore the failure of closing-treatment contributes to the increase in loss
of bee colonies caused by parasites. Experts now agree that a single treatment
is not sufficient against the varroa mite. Harmonization of the appropriate treatment method and timing could improve the effectiveness of the treatment. It
would be necessary to determine the economic threshold to the diagnosis of
the acceptable mite infestation level, but their application is limited to a single
geographical area and to a specific time of the apiculture season. The using of
economic threshold can contribute to the cost-effective beekeeping and can
reduce the harmful effect of unnecessarily applied chemicals on honeybees. In
the fight against varroa mite greater importance should be attributed to the Varroa Sensitive Bees (VSB) in the breeding programmes. Additionally, the examination of Varroa Sensitive Hygiene (VSH) behaviour of col¬onies can provide a
new way of protection against Varroa destructor.

SUMMARY
The usage of antibiotics to treat and prevent bacterial infections in small animals is highly important in the clinical practice. As the use of antibiotics has
become widespread, veterinarians play a significant role and have an outstanding responsibility in spreading resistance amongst bacteria strains and preventing its emergence, as well. To preserve the efficacy of antibiotics in the future,
the usage of antibiotics should be based on the site and the causative agent
of the infection. The clarification of principles for empirical choice of medicines
- beside the importance of the susceptibility test - can help the decision. The
authors summarize the pharmacological aspects of antibiotics that are used in
the small animal practice, detailing their pharmacokinetics, indications, side-effects and their dosage.

SUMMARY
Background: The size of the teat of the cattle changes during milking. The
degree of change in size depends on the breed, age, quantity of milk produced
and the lactation stage, as well.
Objectives: The authors wanted to determine how ultrasound-related teat
parameters change during milking in Holstein-Friesian cows in different lactation stages.
Materials and Methods: The study was carried out on a dairy-farm in Veszprém county of freshly calved cows (n = 40), in the 100-150th day in milk (n =
70) at the end of lactation (n = 40) and freshly calved heifers (n = 31) teats. The
length of the teat canal, the 1 cm area of the paracle papillary and the teat end
area were measured before milking, immediately and two hours after milking.
The authors used SonoScape A6 ultrasound machine and 5-7 MHz linear transducer for the ultrasound examination and SPSS. 18. program for the statistics.
Results and Discussion: Prior to milking, the length of the teat canal and the
area of the teat end was measured significantly higher (p < 0.05) at cows at the
end of lactation, the lowest in heifers. The area of the pars papillaris was significantly (p < 0.05) the smallest at the time of deflation, the highest after calving.
Milking results in significantly (p < 0.05) lengthening the teat canal and the teat
end area but the pars papillaris area is significantly reduced (p < 0.05). In a two hour measurement, the length of the teat canal and the teat end area at the
heifers grow further at the cows in the middle of lactation, while in the other
two groups they decreased. Only in cows at the end of lactation there were no
significant differences (p < 0.05) between the two-hour and pre-milking results.
The area of the pars papillaris increases in all four groups but is still significantly
(p < 0.05) lower than the pre-milking value.

SUMMARY
Background: Exertional myopathies with rhabdomyolysis (ER) is a syndrome
that damages the muscle tissue in horses and can be a devastating problem
among working equidae. Beyond a highly probable hereditary factor, there does
not seem to be a single cause that triggers ER in horses. Among these factors
we can mention: the overfeeding of non-structural carbohydrates, poor conditioning or fitness, sudden increase of workload, electrolyte or mineral imbalances, deficiency in selenium or vitamin E, or imbalance of certain hormones. In
Transylvania there is a certain geographical area of relatively high altitude where
the prevalence of exertional rhabdomyolysis is high compared to the prevalence
in the neighbouring regions.
Objectives: In our manuscript while demonstrating typical cases, we examine
all possible causes and contributing factors which can lead to the high prevalence of the condition, we also describe the pathophysiology of the disease and
critically evaluate the locally applied treatment methods.
Materials and Methods: We describe 5 cases of equine rhabdomyolysis by
presenting the results of feed analysis, physical examination, blood and urine
laboratory measurements, genetic tests and histopathology of muscle biopsy
samples. We follow the clinical courses and treatment responses.
Results and Discussion: In 4 of the 5 cases genetic background of rhabdomyolysis was proved by genetic testing for equine polysaccharide storage myopathy type 1 (PSSM1). Based on the feed analysis, the daily ration of these horses
is deficient in essential amino acids, selenium, vitamin E, and some minerals
and electrolytes. A sudden increase in workload demands high amount of well structured glycogen in the muscles, a perfect electrolyte balance and high antioxidative capacity, all of which are deficient in our cases. To prevent occurrence
of further cases, PSSM1 positive horses should not be used for sudden heavy
anaerobic exercise and it is advised to test any horse for the mutation before
purchase. To avoid any muscular disorder, a well-balanced vitamin and mineral
supplemented daily ration should be fed.

SUMMARY
Background: The authors examined a marbled sailfin pleco (Pterygoplichthys
joselimaianus WEBER, 1991) brought to the clinic of the Department of Exotic
Animal and Wildlife Medicine of the University of Veterinary Medicine in September 2016. The owner purchased the animal in January 2016 in a special aquaristic shop. The owner kept the fish in a 350 l tropical aquarium with other small
sized fish species (Paracheirodon innesi, Danio margaritatus).
Objectives: During the physical examination there was a lentil-sized papilloma-like tumour in the right corner of the mouth. Due to the increasing growth
rate of the tumour the veterinary team of the clinic decided to perform removal
surgery on the fish. The authors used the removed tissue to perform histopathological examination to identify the type of the tumour .
Materials and Methods: The veterinary team examined the fish and prepared
the anaesthesia bath. The bath contained 0,170 mg/ml MS-222 (tricaine meth anesulfonate), an anaesthetic commonly used in fish veterinary procedures.
After removing the tumour, the wound was treated with Betadine ointment. The
tissue was fixed for 24 hours in buffered formalin. After the fixation the sample was infiltrated and embedded into paraffin blocks. Leica manual microtome
was used for section cutting. The prepared histological slides were stained with
haematoxylin and eosin and were examined with Olympus CX21 microscope. The
identified tumour was compared to neoplasms found in other ornamental fish
species described earlier in literature review.
Results and Discussion: After the results of the histopathological examination
the tumour was identified as a papilloma. According to the authors’ hypothesis
the tumour was caused by a mechanical trauma or an injury. Nowadays in aquaristic owning high-priced fish species is increasing in popularity. However, these
valuable species require adequate veterinary supervision, prevention, diagnostics and treatment as well.

SUMMARY
Background: The oral hygiene in dogs depends mostly on the quality of con sumed food and plaque removal performed by the owner. In neglected cases
severe, irreversible periodontitis with pockets containing anaerobic bacterial
flora could evolve in months or years.
Objectives: The aim of this study was to isolate Porphyromonas spp. and Prevotella spp. from subgingival samples taken from dogs with moderate to severe
clinical periodontal diseases, and the susceptibility testing of these strains, with
special regard to pradofloxacin.
Materials and Methods: Samples for the study were collected while the dogs
were under general anaesthesia. We collected 150 periodontal samples from 59
dogs. The samples were shipped directly to Duo-Bakt Laboratórium, Budapest,
Hungary. At Duo-Bakt Laboratórium the samples were inoculated on a Wilkins–
Chalgren (incl. 8% sheep blood) plate and on another plate, which included nalidixic acid and colistin. All plates were incubated in an anaerobic environment
at 35 °C for 5–7 days, after which all pigmented colonies and the suspected
non-pigmented Prevotella spp. colonies were selected. The identification was
performed by analysing the morphology of the colonies, pigmentation, and the
results of the presumptive tests. Final identification was performed by MALDITOF-mass spectroscopy.
Results and Discussion: During the study, 74 Porphyromonas and 2 Prevotella
isolates were isolated, identified and transported to Laboklin, Bad Kissingen,
Germany for antibacterial susceptibility testing. According to our results, pradofloxacin could be a promising choice in the treatment of periodontitis as in most
cases the MIC values were under 0.1 mg/l. Based on our clinical experiences
and the MIC values, amoxicillin-clavulanic-acid is still an appropriate antibiotic
for the treatment of periodontal diseases in dogs, however, resistant strains to
clindamycin and metronidazole were found. These antibacterial susceptibility
test results could help veterinarians to create the best protocols for the treatment of periodontitis.

SUMMARY
Background: Prolapse of the third eyelid gland is the most common primary
disorder of the canine nictitating membrane.
Objectives: The aim of the present histopathological, immunohistochemical
study was to describe microscopic pathomorphological lesions of the parenchyma, and the interstitium of the surgically removed prolapsed canine third
eyelid glands (TEG), compared to the normal ones.
Materials and Methods: Five intact, and 26 surgically removed prolapsed TEG
samples were separated and conserved in buffered, 8% formalin for 24 hours at
room temperature, embedded in paraffin wax and further processed for sectioning (3–4 µm) and immunohistochemistry (antibodies: anti-pancytokeratin, and
anti-E-cadherine).
Results and Discussion: Histopathological lesions included (n = 26): 53.84% (n
= 14) acute purulent parenchymatous adenitis, which was accompanied by with
acute purulent ductal inflammation in 9 cases; 34.61% (n = 9) subacute-chronic
lymphocytic interstitial adenitis, coupled with acinar degeneration and necrosis
in 8 cases; 30.77% (n = 8) interstitial fibrosis; 3.85% (n = 1) adenoma. During the
immunohistochemical investigations, the inflamed, degenerated TEG showed
weaker or even loss of the pancytokeratin-, and E-cadherine-expression.

SUMMARY
Tail biting is one of the most serious welfare challenges in the modern pig industry. There are several attempts to prevent or treat this abnormal behaviour which
typically develops after weaning and during the fattening stage. The life of modern pig breeds has changed dramatically compared to their ancestor, the wild
boar. However, their behavioural repertoire is still the same and has not changed
fundamentally over thousands of years of domestication. In their natural habitat
pigs are exploring their environment, searching for food, rooting or chewing, in
75% of their active period of the day. In modern pig houses animals are kept
in small and fundamentally barren environment compared to the wild. Food is
provided in food trays, which are often too small for the whole group to feed
altogether. Consequently, the smallest and weakest individuals are displaced
from the feeder by their more developed counterparts. Not only the displacement, but also the chewing and rooting deprivation may trigger the motivation
to bite pen-mates’ tails or even ears and flanks. When considering both the
motivational background and form of the behaviour, there are at least 3 different
types of tail biting behaviour, e.g. two-stage, sudden-forceful and obsessive,
with large individual differences in response. There are several environmental
and individual factors that predispose a pig to develop biting, become a victim
or stay neutral (neither bite nor being bitten by others).
Tail biting may be prevented by tail docking, and about 90% of fattening pigs are
docked in the EU. However, it has been reported that 2 - 5% of docked pigs are
still bitten by pen-mates. The proportion of bitten animals in undocked stocks
has been found to be up to 30%. Although genetic selection for more tolerant
individuals might be a promising solution for breeders, there are preventative
measures that can be done to decrease the occurrence of this unwanted behaviour. Detecting the first signs of the outbreak is crucial. Early removal of the biters and bitten animals, and providing straw or any other chewable material can
strongly reduce the occurrence of tail biting.
