Resumo(s)
Campylobacter jejuni and Campylobacter coli are carried in the intestinal tract of a wide variery of wild and domestic animais, many used for food production, and constitute an unlimited source of human campylobacteriosis. There is ample evidence to indicate poultry, especially broiler chickens, as an important reservoir of Campylobacter jejuni and poultry products as principal vehicle of Campylobacter infection in men (2,3,4,7,9,10). According to Tauxe (12), the bulk of infections are sporadic, most of them associated with the consumption or handling of poultry meat. The comparison of human and poultry isolates showed a very strong similarity in any studies (3,8,12). All birds at the production stage may be colonized before slaughter. At the abattoir the carcasses and derived products will be contaminated as a result of faecal contact during processing (5,7,10).
The widespread use of antimicrobial agents as therapeutics and feed additives may lead to the development of resistant strains with serious consequences for animal and human health.
This study assessed the prevalence of C. jejuni and C. coli at the production stage and slaughter in a industrial poultry region of Portugal, to evaluate their relative importance as potential reservoirs of human campylobactenosis.
The antimicrobiol resistance profile of the thermophilic organisms isolated from four broiler flocks were studied. The correlation of the occurrence of antimicrobial resistance with the general use of antimicrobial agents in veterinary husbandry was studied.
