| ABSTRACT: The present study aimed to describe and characterize a nosocomial outbreak caused by a multidrug resistant Salmonella Typhimurium in hospitalized calves at a veterinary medical teaching hospital from Brazil. Sixty-three (96.9%) calves showed lethargy, hyperthermia and profuse diarrhea and despite treatment, 26 (41.2%) animals died. Five animals were necropsied and stool samples of six calves were collected. The isolated strains were subjected to antimicrobial susceptibility test by disc-difusion method and were fingerprinted by ERIC-PCR. Macroscopic lesions suggestive of salmonellosis, such as fibrinonecrotic enteritis and hepatosplenomegaly were observed. Salmonellosis was confirmed by isolation of S. Typhimurium from stool samples and organs... |

| ABSTRACT: The present study aimed to describe and characterize, for the first time, two outbreaks of salmonellosis caused by Salmonella Ndolo in foals and calves in Brazil and compare the isolated strains with S. Ndolo previously identified in asymptomatic reptiles. The affected calves and foals presented fever, lethargy, and profuse diarrhea. Isolated strains were subjected to antimicrobial susceptibility testing, characterized according to virulence genes, and fingerprinted by ERIC-PCR. Salmonella Ndolo was identified in fecal samples from two foals and four calves. One isolate from a calf was resistant to amoxicillin/clavulanic acid, trimethoprim/sulfamethoxazole, and florfenicol. Strains from two other calves were resistant to oxytetracycline. All... |

| ABSTRACT: A 10-day old foal presented with a history of acute recumbency and generalized weakness, that progressed to seizure episodes and death. Post mortem examination revealed necrotizing and purulent omphalophlebitis and fibrinopurulent meningoencephalomyelitis. Salmonella Typhimurium was isolated from the central nervous system and determined to be the cause of the meningoencephalomyelitis. Due to the lack of evidence of gastrointestinal disease, the umbilical cord was considered the most likely portal of entry of the bacteria. The isolated S. Typhimurium was resistant to ampicillin and cephalotin, and partially resistant to enrofloxacin. These drugs are commonly used in the treatment of salmonellosis. This is the first report of S. Typhimurium... |
