چکیده

Approximately 57% of clinical and 33% of poultry isolates examined produced a cytotoxin. Cytotoxic activity was detected in 25 (50%) isolates of Campylobacter of which 12 were isolated from bloody diarrhea and 9 from watery stools. The cytotoxin titers were low, ranging from 2 to 16. The crude filtrates from 50 Campylobacter isolates showed no cytotoxic effect in Vero cells, no fluid accumulation in suckling mice and no hemolytic activity.

Occurrence of virulence genes and strain diversity of thermophilic campylobacters isolated from cattle and sheep faecal samples

The objective of this study was to investigate the genotypic characteristics of Campylobacter isolates in Shiraz, Iran. A total of 40 Campylobacter isolates including 20 C. jejuni and 20 C. coli were recovered from both cattle and sheep faeces by cultivation methods. The isolates were identified on the basis of polymerase chain reaction (PCR) detection of 16SrRNA and multiplex PCR to determine ...

Freezing as an intervention to reduce the numbers of campylobacters isolated from chicken livers.

The aims of this study were (i) to determine the prevalence and numbers of campylobacters in 63 samples of raw livers purchased at retail across the UK and (ii) to investigate whether the freezing of chicken livers contaminated with Campylobacter was a reliable method for decontamination. Chicken livers naturally contaminated with campylobacters were subjected to freezing at -15 and -25°C for o...
