OBJECTIVES To compare the prevalence of antibodies against Marek's disease herpes virus (MDV) and against avian leukosis viruses type C (ALV) in groups of workers exposed to poultry and in unexposed groups. METHODS Antibodies directed against avian viral proteins were detected by enzyme linked immunosorbent assay in 549 subjects. Exposure to chickens was high in two subgroups: farmers on inte...

Thermotolerant Campylobacter spp. are a major cause of foodborne gastrointestinal infections worldwide. The linkage of human campylobacteriosis and poultry has been widely described. In this study we aimed to investigate the prevalence, antimicrobial resistance and genetic diversity of C. coli and C. jejuni in broilers from Ecuador. Caecal content from 379 randomly selected broiler batches orig...

Bovine tuberculosis (bTB) is a chronic progressive disease caused by Mycobacterium bovis an important zoonosis worldwide. aim this study was conduct analyses secondary database bTB-positive cases registered Federal Inspection Service tw...

The aim of the present study was to determine the frequency and distribution of Salmonella contaminations throughout the slaughtering process of pigs. The investigation was carried out in two slaughterhouses that were visited four times each on different days. Samples were taken from lairage areas, fecal contents, carcasses at different stages of processing and from the environment. Bacteriolog...

AIMS The purpose of this study was to investigate the prevalence of Salmonella in pigs at the moment of slaughter and in the slaughterhouse environment. METHODS AND RESULTS In total, five different commercial slaughterhouses were sampled during eight slaughterhouse visits. Carcass swabs, colon content and mesenteric lymph nodes were taken to reflect the animal status and from the slaughterhou...

This study was conducted to investigate first the bacterial contamination by Enterobacteriaceae, fecal coliforms and prevalence of Salmonella spp. second identify main associated risk factors in Algerian farms, slaughterhouses butcheries during a two-years period. Thus, cross-sectional performed using simple random sampling method target 20 10 5 butc...

Background and Aim: Antibiotic resistance occurs when bacteria can avoid the mechanisms of action antibiotic drugs, resulting in a reduced activity. This is dangerous for animals humans because treatment infectious diseases take longer may even lead to failure. Bacteria meat be cause meat-borne consumers. study aimed determine profile Escherichia coli from broiler slaughtered several local gove...
