Etude de l'influence du nettoyage et de la désinfection et des procédés d'abattage en abattoir de volaille sur le niveau de résistance aux antibiotiques des campylobacters

Abstract : Campylobacter is a common cause of human bacterial enteritis and consumption of poultry products is a major source of human infection. It has been suggested that disinfectants and environmental stress can lead to changes in the nature and scale of antibiotic resistance expressed by bacteria. In order to investigate this hypothesis, sampling of poultry and environment in 4 unrelated slaughterhouses were conducted. Minimal inhibitory concentrations (MIC) against 6 antibiotics and 2 disinfectants were measured for all the isolates collected. Genotype profile of selected isolates collected after cleaning and disinfection and from poultry carcasses was done by PCR-restriction fragment length polymorphism of pfla/gyrA and flaA genes. Our results indicate that campylobacter is able to survive overnight on surfaces of poultry slaughterhouses and that these strains may contaminate carcasses during the slaughter process. Our results also suggest that cleaning and disinfection procedures and shlaughter procces don't lead to increase antibiotic resistance in campylobacter.
