Aflatoxins Aggravate the Incidence of Salmonellosis Outbreak in Fattening Calves: A Case Study
Fever, bloody diarrhea and high mortality rate were the main clinical finding in a group of fattening calves. Analysis of corn silage revealed presence of aflatoxins at level of 370 ppb. This level of aflatoxins in the feed of cattle is somewhat low to be the main cause of reported signs. Leukocytopenia, anemia, decreased lymphocytic activity and lowered phagocytic index are the main hematologi...
متن کاملSalmonella pathogenicity island 2 influences both systemic salmonellosis and Salmonella-induced enteritis in calves.
We have used signature-tagged mutagenesis to identify mutants of the host-specific Salmonella enterica serotype Dublin which were avirulent in calves and/or BALB/c mice. A mutant with a transposon insertion in the sseD gene of Salmonella pathogenicity island 2 (SPI-2), which encodes a putative secreted effector protein, was identified. This mutant was recovered from the bovine host but not from...

متن کاملa study on the clinical features of salmonellosis and prevalence of salmonella serogroups in calves
the clinical features of salmonellosis and prevalence of salmonella serogroups in calves were studied on one hundred and thirty two suspected calves in dairy farms around tehran. clinical examinations were carried out and the faecal or tissue (if calve was euthanized or dead) samples were collected for bacterial culture. the results were analyzed with chi-square statistical test. salmonella spp...
متن کاملBacterial intestinal flora associated with enterotoxaemia in Belgian Blue calves.
The enterotoxaemia syndrome in Belgian Blue calves is characterised by a high case fatality rate, sudden death, lesions of haemorrhagic enteritis of the small intestine and, quite often an absence of other clinical signs but its cause has not been yet identified. As a first step in this identification, the aerobic and anaerobic intestinal flora of a population of 78 calves, originating from far...
