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

This study was conducted to investigate the prevalence of Newcastle Disease, Avian Influenza, Infectious Bronchitis, and Infectious laryngotracheitis in some regions of Tripoli-Libya. Serum samples were collected from Four broiler farms in Wadi Alrabea area, two layer farms and one backyard farm in Gaser Bin Gasher, two layer farms in Alswani and one backyard farm in Zliten City and screened for the presence of antibodies against LPAI-H9, HPIA-H5, HPIA-H7, ND, IB 4/91 strain using the HI test and antibodies against ILT virus by ELISA. The overall seroprevalence of H9, H5, H7, ND, IB4/91 and ILT was 26.5%,0%,0%,, 29.5%,43% and 30% respectively. All sera tested for AI-H5 and AI-H7 were negative. In Wadi Alrabea flocks, seroprevalence of H9, H5, H7, ND, IB4/91 and ILT was 44%, 0%, 0%, 16.28%, 32.56% and 0% respectively. Where as in Gaser Bin Ghasher, was 24%,0%, 0%, 33.87, 36.29% and 39% respectively. In Alswani, the seroprevalence was 8.70%, 0%, 0%, 52.17%, 54.35% and 54.3%. The seroprevalence of H9, H5, H7 in Gaser Bin Ghasher backyard chickens was 23%, 0%, 0% respectively and the seroprevalence of H9, H5, H7, ND, IB4/91 of Zliten backyards was 12%, 0%, 0%, 12%, 96% respectively. Further investigations are recommended to identify the circulating virus genotypes and models of transmission for better understanding of these viruses epidemiology in backyard chickens in Libya. Vaccination of backyard chickens against ND using heat resistant strain is highly recommended.

In order to study microscopic and macroscopic lesions in chickens infected with low and high doses of Salmonella enteritidis PT 4 (SE), 150 one-day-old White Plymouth Rock chicks were divided into three groups each containing 50 birds. The chickens of the first and second groups were inoculated with 2 x 102 and 2 x 108 cfu of Salmonella, respectively. The chicks of the third group were kept as uninoculated control birds. Five birds from each group were euthanized by cervical dislocation at 6, 12, 18 hours post inoculation (hpi) and then after 1, 3, 7, 10, 14, 21, and 27 days post inoculation (dpi) and were examined for presence of gross and histological lesions. Catarrhal typhlitis and unabsorbed yolk sac were the most prevalent gross lesions in both groups. Histologically, granulomatous nodules in the caecum were found occasionally in some cases in both inoculated groups. The present study demonstrated that the chickens infected with a low dose of SE showed fewer lesions, which were milder in comparison with the birds inoculated with a high dose of SE. It suggests that chickens were able to capture the pathogen in the low dose group
