Abstract
This study amid to determine the prevalence of Salmonella enteritidis and multi-drug resistant in some chicken slaughterhouses in Tripoli -Libya. The study include three regions of Tripoli namely south, East and West regions. Five slaughterhouses were selected from each region. every chicken slaughterhouse was visited 3 time for sample collection with 2 weeks interval. Samples were collected from neck skin, crop and spleen from 5 chicken. Total of samples from all regions were 675. Every 5 samples were processed for isolation and identification by biochemical identification and serotyping and antibiotic sensitivity test. The total rate of isolation of Salmonella spp was found to be 15% and Salmonella enteritidis was 7%. The highest prevalence 9% of Salmonella enteritidis was recorded in south region of Tripoli, however, the highest prevalence of Salmonella spp was found in West region. the prevalence of Salmonella was significantly (P <0.01) higher in spleen (13%) as compared with crop and neck. based on resistance pattern, Salmonella spp isolated from spleen had highest MAR index value of 0.86 in south region followed by MAR index value of 0.8 in west region and MAR index value of 0.46 in the East region. A high prevalence rate of Salmonella enteritidis contamination was found in slaughterhouses in south region. These results showed the foremost hazardous role of poultry production in the spared and persistence of salmonella contamination in studied regions
