Abstract

A sertések légzőszervi tünetegyüttese (Porcine Respiratory Disease Complex, PRDC) nagy gazdasági károkat okozhat a sertésállományokban. A multifaktoriális PRDC kórokozóinak feltérképezése során a baktériumok közül a zoonotikus Bergeyella zoohelcum is azonosítására került már. A szerzők a cikkben röviden áttekintik a Bergeyella nemzetségbe tartozó jelentősebb baktériumokat, majd esetismertetésükben leírják és jellemzik a laboratóriumba beérkezett sertéstüdőminták kórbonctani elváltozásait és a baktériumtenyésztés, valamint az antibiotikumérzékenységi vizsgálat során kapott eredményeket. A vizsgált magyarországi sertésmintában Bergeyella zoohelcum került kimutatásra. 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.
