Abstract Background Mycoplasma hyorhinis is an invader of the upper respiratory tract in swine that is considered to have ubiquitous distribution. It is mainly known for causing polyserositis and polyarthritis in weaned piglets, even though the mechanisms of systemic spread are not fully understood. Mycoplasma hyorhinis has also been associated with other diseases in pigs such as pneumonia or otitis media, but so far has not been known to cause central nervous disorders. This case series reports the isolation of Mycoplasma hyorhinis from cerebrospinal fluid and/ or meningeal swabs from piglets originating from four different piglet producing farms in Austria. Case presentation On farm 1, coughing, stiff movement and central nervous signs occurred in nursery piglets. Mycoplasma hyorhinis was the only pathogen isolated from meningeal swabs from two piglets showing central nervous signs. Fibrinopurulent leptomeningitis was only observed in one piglet. Only one of two nursery piglets from farm 2 showed mild central nervous signs but no histologic lesions; Mycoplasma hyorhinis was isolated from cerebrospinal fluid of the piglet with neurologic signs. Mycoplasma hyorhinis was isolated from cerebrospinal fluid of all three investigated piglets from farm 3, all of which showed central nervous signs and purulent leptomeningitis. Further, Streptococcus suis was isolated from the cerebrospinal fluid of one piglet. Fibrinopurulent leptomeningitis was detected in two piglets from farm 4 that had died overnight without showing any clinical signs and Mycoplasma hyorhinis was isolated from meningeal swabs from both piglets. Conclusion While causality has yet to be proven by experimental infection and in situ detection of the pathogen in histologic sections, the findings of this study and the absence of other pathogens suggest Mycoplasma hyorhinis as a potential causative agent of meningitis in swine.

Resumo: Para avaliação dos aspectos patológicos e microbiológicos de casos clínicos de doenças respiratórias em suínos de terminação foram analisados 75 suínos doentes oriundos de 36 lotes. Suínos que apresentavam sinais clínicos respiratórios evidentes foram necropsiados para avaliação macroscópica e colheita de amostras para análise histopatológica e microbiológica. Foram realizados testes de isolamento bacteriano para as principais bactérias do sistema respiratório dos suínos, PCR para Mycoplasma hyorhinis, imuno-histoquímica para Influenza A, Circovirus suíno tipo 2 e Mycoplasma hyopneumoniae. A sensibilidade antimicrobiana de 24 amostras de Pasteurella multocida tipo A foi avaliada por testes de concentração inibitória mínima para os principais antimicrobianos utilizados em suinocultura. Mycoplasma hyopneumoniae e Pasteurella multocida tipo A foram os agentes infecciosos mais prevalentes. Broncopneumonia supurativa e pleurite foram as principais lesões respiratórias encontradas. Pasteurella multocida tipo A, quando presente, aumentou a extensão das lesões pulmonares. Todas as amostras de Pasteurella multocida testadas foram sensíveis aos antimicrobianos Doxiciclina, Enrofloxacina e Tilmicosina. Em 58% das amostras foi identificado mais de um agente infeccioso, evidenciando a alta prevalência da associação de agentes nas doenças respiratórias de suínos em terminação.
