Mycoplasma é um patógeno altamente contagioso, podendo causar mastite, pneumonia, artrite, entre outras enfermidades. Seu isolamento requer meios e condições específicas devido ao seu crescimento fastidioso. Devido à complexidade do seu diagnóstico, acredita-se que a real prevalência de casos de ...
The stable fly Stomoxys calcitrans (Linnaeus, 1758) has been described as a potential spreader of infectious agents to cattle herds. Among the agents transmitted by this fly, Escherichia coli has attracted attention due to its potential to cause gastrointestinal disorders as well as environmental mastiti...
The pods of Enterolobium spp (Leg.Mimosoideae) are said to cause photsensitivity and abortion in cattle. The pods of E. contortisiliquum and E. timbouva ("tamboril" or "timbaúba"), collected at various localities, in two occasions during outbreaks of photosensitization and abortions, were fed in single ...
Cento e oitenta e sete amostras de diferentes tecidos provenientes de 71 bovinos, oriundos de vários Estados do país, foram processados para isolamento de microrganismos anaeróbios, sendo de cada uma delas isolada pelo menos uma cepa, caracterizada como Clostridium spp. Destas, 144 foram identificadas...
E. coli O157 : H7 é um patógeno de importância em alimentos, tendo sido envolvido, nos últimos anos, em surtos de grandes proporçSes, principalmente por produtos cárneos. Entretanto sua ocorrência em alimentos, particularmente em carne crua, é baixa e poderia, eventualmente, ser atribuída à ati...
