“…In contrast, summer mastitis is reported particularly as outbreaks in pastured cattle with access to ponds and wet areas during summer months in Europe (Radostits et al 2007). In Brazil, an outbreak of bovine mastitis caused by T. pyogenes was described in a dairy farm with history of a sudden increase of clinical cases after a long rainy period and a peak in the fly population, which was characterized as summer mastitis (Motta et al 2011). In this study, 65 (45.1%) cases of mastitis were described, confirming mammary infections as a major manifestation of T. pyogenes infections in this species, predominantly bovine clinical cases.…”

“…Bovine mastitis in heifers and dry cows appears to be the most common clinical picture of T. pyogenes infections in livestock (Radostits et al 2007;Ruegg 2010). Nevertheless, the knowledge on T. pyogenes infections among domestic animals is fragmented and restricted to the report of cases or outbreaks (Motta et al 2011). Thus, few studies have focused on the major clinical and epidemiological aspects of T. pyogenes infections involving a great number of animals.…”

Background: Formerly, Arcanobacterium pyogenes was recently renamed Trueperella pyogenes. This opportunistic bacterium is related to miscellaneous pyogenic infections in animals. Most studies involving T. pyogenes are case reports, whereas few surveys have focused the major aspects of T. pyogenes infections involving a case series study design. Objective: The aim of this study was to retrospectively evaluate selected epidemiological and clinical aspects, as well as the in vitro antimicrobial susceptibility pattern of 144 cases of T. pyogenes infections among domestic animals from 2002 to 2012. Animals and methods: T. pyogenes was isolated from different clinical specimens from cattle, goats, sheep, pigs, horses, dogs, and buffaloes. Correlations were assessed by the Chi-square or Fisher's exact tests. Results: Mastitis (45.1%), abscesses (18.0%), pneumonia (11.1%), and lymphadenitis (9.0%) were the most common clinical manifestations. In addition, the organism was also isolated from other miscellaneous clinical specimens from cases of septicemia, encephalitis, pyometra, prostatitis, orchitis, seminal vesiculitis, pericarditis, and omphalitis. No statistical association was observed between T. pyogenes infections and age, gender, or season across the study. The most effective drugs against the pathogen were florfenicol (99.1%), cefoperazone (96.0%), cephalexin (95.0%), and ceftiofur (94.8%). High resistance rates were observed against trimethoprim-sulfamethoxazole (49.3%), followed by norfloxacin (10.9%) and tetracycline (9.2%). Conclusions: This study highlights the diversity of clinical manifestations and the opportunistic behavior of T. pyogenes infections in domestic animals, with predominance of mastitis, abscesses, pneumonia, and lymphadenitis. It also reinforces the importance of knowing the susceptibility profile before initiating therapy, to improve antimicrobial therapy approaches.

“…A forma da bactéria penetrar nos tetos é por lesões, a doença é severa com possíveis fístulas que drenam pus, nódulos e abcessos e de difícil eliminação com antibióticos (Gomes, 2013). Nesse estudo foi isolada em dez das 85 amostras (12%), em outro estudo realizado em uma propriedade de São Paulo a frequência foi de 17% em 216 animais e foi considerado um surto ocorrido nos meses de janeiro e fevereiro de 2010 (Motta et al, 2011).

RESUMO: Para a produção do nobre alimento leite com qualidade a sanidade do rebanho, principalmente do úbere dos animais é de extrema importância. Dessa forma a mastite, inflamação da glândula mamária é a doença mais cara na produção leiteira, e o maior prejuízo gerado por ela é a diminuição do volume produzido, na maioria das vezes invisível. O diagnóstico microbiológico é considerado a prova de ouro na descoberta do perfil microbiológico da localidade ou propriedade e fundamental na elaboração de um programa de controle e prevenção dessa enfermidade. O presente estudo foi baseado na tabulação de resultados de isolamentos microbiológicos e teve por principal objetivo informar o perfil microbiológico da região. As amostras, sem histórico clínico, eram provenientes de propriedades do sudoeste do Paraná, colhidas por veterinários ou produtores e encaminhadas ao laboratório com objetivo diagnóstico. Totalizaram 138 amostras entre o período de setembro de 2013 a setembro de 2014. Nos resultados observou-se um grande percentual de amostras negativas (19%) e contaminadas (17%), os quais mostram a importância de uma colheita e armazenamento corretos para um resultado satisfatório. Quanto ao perfil, os gêneros mais isolados foram o Streptococcus spp. (19%), Staphylococcus spp. (16%) e Nocardia spp. (8%) e as bactérias causadoras das mastites contagiosas foram mais representativas com 56%, enquanto as causadoras das mastites ambientais foram 44% do total de amostras com isolamento. Essas informações devem auxiliar os profissionais em decisões estratégicas de melhoria nas propriedades leiteiras, visto que anteriormente não havia nenhum trabalho como esse na importante bacia leiteira do sudoeste do estado.Palavras-chave: isolamento; mastite; microrganismos ABSTRACT:. For the production of the noble food milk with quality, the health of the cattle and their udder is the most important one. In this way, the mastitis, inflammation of the mammary gland is the most expensive disease in the milk production, and the most damage caused by it is the reduction of the volume produced, mostly invisible. The diagnosis microbiological is considered the gold proof is the discovery of the microbiological profile of the local or the farms and principal in the elaboration of a control program and prevention of this disease. This study was based on the tab of the results of microbiological insulation and was aimed to inform the microbiological profile the region. The samples, without historical clinical, were from the farm of the southwest of Paraná, picked up by veterinarians or farmers and forwarded to the laboratory with an objective diagnosis. A hundred and thirty-eight samples were totaled between the period September 2013 to September 2014. The results showed a great percentage of negative samples (19%) and contaminated (17%), which shows the importance of a correct harvest and storage for a satisfactory result. As profile, the most isolated gender were the Streptococcus spp. (19%), Staphylococcus spp. (16%) and Nocardia spp. (8%) and ...
