A szarvasmarhák légzőszervi betegségkomplexének klinikai és labordiagnosztikai vonatkozásai a telepi állatorvosi gyakorlatban : Irodalmi összefoglaló

Abstract

The pathogenesis of bovine respiratory disease complex (BRDC) in cattle is well known. As a multifactorial disease, the understanding of the interactions between the environment, the pathogens and the host are essential and requires a complex approache. Successful management of the disease integrates the recognition of pathogens and predisposing management and environmental factors, the effective diagnostics and targeted, timely treatment. Regular and thorough clinical examination is often problematic in practical farm conditions due to the limited time, manpower, and technical and environmental conditions. Fortunately, a wide range of clinical scoring systems are developed as suitable and practical methods monitoring the presence of sick animals at individual and group level in the herds. In addition, a wide range of laboratory diagnostic tools and methods are available to veterinary practitioners. Some tests can be performed on farm, or even can be integrated into the routine herd health management practices of the farm. However, the conclusions that can be drawn from laboratory tests are largely determined by the type of samples and the sampling conditions. For this reason, our goal was to overview the practical methods and tools and their clinical, diagnostic and herd-health relevance. The most important diagnostic laboratory methods are also discussed regarding their benefits and limitations, the relevant informations about the aspects of sample collection and prelaboratory sample handling, as well as the interpretation of the laboratory results and their use in the herd health management practices. The present study aims to help the field veterinary practitioners to get relevant informations for improving the effectiveness of their diagnostic, therapeutic and preventive activities in the herd-health control of BRDC in the cattle farms.
