Abstract
Human Campylobacters are considered one of the most common causes of food poisoning in man. Campylobacter jejuni and Campylobacter coli are ubiquitous in temperate environments. Both species colonize the intestinal mucosa of most warm-blooded hosts, including all food-producing animals and humans. Thereby, this study was carried out to study the role of different food producing animal species (cattle, sheep and buffaloes) including broilers and minced meat in transmitting of Campylobacter spp. to humans live in Sharkia Province, Egypt.
6.1 Occurrence of Campylobacter species in different samples collected in Zagazig, Egypt:
• A total of 572 samples from human (stool, n=110), chicken (125 cloacal swabs, 61 thigh meat, 58 breast meat, and 61 neck skin) and ruminants (rectal swabs of cattle (n=55), buffaloes (n=25), and sheep (n=35) and 42 minced meat samples) were collected from Zagazig city, Sharkia Province, Egypt during the period extended from September, 2012 to April, 2013.
• All samples were screened for the presence of Campylobacter spp.
• In chicken, Campylobacters were isolated from 27 cloacal swabs (21.6%), 29 neck skin (47.5%), 15 breast meat (25.9%) and 29 thigh meat (47.5%).
• C. jejuni were identified in cloacal swabs and neck skin ( 1 sample, each, 3.7%) and in 2 thigh meat (6.9%). While, C.
