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

Infectious Laryngotracheitis (ILT) is a viral respiratory disease of poultry caused by Gallid herpesvirus 1 leading to severe economic losses. The aim of the current study was to isolate and identify ILT virus in suspected outbreaks of one broiler flock (farm 1) and three layer flocks (farms 2,3 and 4) located in Tripoli. Samples of trachea were collected and preserved in transport media for viral isolation and some were preserved in 10% neutral formalin for histopathology. Broiler and Layer flocks were serologically monitored and tested for the presence of antibodies by ELISA against ILTV at first days old and later at slaughter age for broilers and before the onset of production for layers in which total of 290 blood samples were collected from six poultry farms (3 broiler flocks and 3 layer flocks). Following isolation of the virus in fertile eggs, chorio-allantoic membrane (CAM) samples were confirmed by PCR and histopathology. The lesions seen on the CAMs were congestion, hemorrhages and pocks after 5 days post inoculation. Samples from farm 1 and 3 were positive whereas other farms were negative. Histopathology of CAMs revealed edema, congestion, haemorrhages, infiltration of heterophils and mononuclear cells, and presence of syncytial cells containing intranuclear inclusion bodies. The trachea revealed severe destruction and sloughing of the mucosa due to necrosis. The results of this study confirmed the circulation of ILTV in commercial poultry flocks and highlighted the need for more epidemiologic investigation of the disease arabic 16 English 96
