| dc.description.abstract | Background: Porcine respiratory disease complex (PRDC) can cause large economic losses in swine herds. The PRDC is primary caused by pathogens such
as Porcine Reproductive and Respiratory Syndrome Virus (PRRS), Swine Influenza Virus (SIV), Porcine Circovirus Type-2 (PCV2), Mycoplasma hyopneumoniae (M.
hyo) and Actinobacillus pleuropneumoiae (APP), which are often associated with
secondary infections caused by agents such as Pasteurella multocida and Streptococcus suis. Mapping the respiratory microbiome of pigs revealed a zoonotic
bacterial species, Bergeyella zoohelcum.
Objectives: The authors briefly review the major species of the Bergeyella genus
and present a case, describing the pathological lesions of swine lung samples
from a Hungarian pig herd and the results of bacterial culture test and antibiotic
sensitivity test.
Materials and Methods: In February 2020, during a slaughterhouse monitoring
check two swine lung samples suspected of being infected with Pasteurella multocida and Actinobacillus pleuropneumoniae were sent into the laboratory of the
University of Veterinary Medicine Budapest for further investigation.
Results and Discussion: Bergeyella zoohelcum and Pasteurella multocida were
detected in the lungs. In the antibiotic sensitivity test, ceftiofur, oxytetracycline,
doxycycline, enrofloxacin, marbofloxacin, flumequine and florfenicol were found
to be the most effective against Bergeyella zoohelcum, while it was resistant
to streptomycin and the combination of trimethoprim and sulfamethoxazole.
Bergeyella zoohelcum is a Gram-negative, aerobic and immotile bacterium that
is part of the oral and/or upper respiratory microbiota of dogs, cats and pigs.
In humans, cellulitis, lymphangitis, septicaemia, foot abscesses, tenosynovitis,
pneumonia, meningitis, endocarditis and diarrhoea may develop following animal bites due to this zoonotic bacterium. This was the first case in Hungary when
Bergeyella zoohelcum was identified from pigs. | en_US |
