virus infection continues to be an important public health concern with regard to blood transfusion in Libya and in Africa. This concern is related to the screening test. Objectives: The main aim of this study to investigate the blood donors samples for HIV, HBV and HCV infections in Tripoli-Libya, North Africa during the first five months of 2015. Methods: The total of 686 blood samples obtained from healthy blood donors who attended Tripoli’s central blood bank, were tested for HBsAg, HCV and HIV using the VITROS® 3600 Immunodiagnostic System. Results: From the 686 samples examined, the frequency of HBsAg positive cases was 0.8%, the number of anti-HBc positive samples was found to be particularly high in the age group 29 and 36 years (p= 0.0001). The number of anti-HBc positive samples was found to be particularly high in the age group 30-39 years (p= 0.01). Most occupation that had positivity with anti-HBc and HBV-DNA were free workers and was less in students. Most positive cases were from east of Tripoli the capital (Tagora, Soq-Aljomaha). Conclusion: The frequency of HBsAg positive blood donors and anti-HBc among this sample was 0.8% and 0.7% respectively, which is low compared with the international findings. The current study estimated the expected exclusion rate of anti-HBc and HBsAg positive donated blood, as this would be an important factor to consider before donation. arabic 16 English 63

Aims: This work was carried out to screen for the presence of bacteria in roasted chicken sold in the market, poultries shop and restaurants in Tripoli. Study Design: A total of 25 roasted chicken and 25 raw chicken parts randomly collected from different selling points in Tripoli. Place and Duration of Study: Microbiology laboratory in microbiology and immunology department in the faculty of pharmacy in university of Tripoli, January 2013 to September 2013. Methodology: Bacteriologically examined using the standard microbiological method according to Based on the colonial morphological and biochemical test, the following bacteria species were isolated. Results: Prevalence of Salmonella was higher in raw chicken samples (100%) compared to the roasted one (28%), E. coli was detected in both raw and roasted chicken (32%), whereas Shigella and E. coli O157:H7 were detected only in roasted chicken [(8%) and (24%)] respectively. Conclusion: The study found that the raw chicken samples were more susceptible to bacterial contamination than the roasted chicken samples, therefore special strategies are needed to decrease the prevalence of bacterial pathogens in chicken samples present in Tripoli area. Therefore good handling/hygiene in processing and preheating of roasted chicken before consumption is recommended.

Toxoplasmosis is a zoonotic disease caused by Toxoplasma gondii. Risk factors include consumption of undercooked meat, raw vegetables, and unfiltered water. Aim: This study aims to screen antibodies titer in toxoplasmosis positive patients in Asabieh city in Libya and to screen risk factors associated with infection in this area. Study design: Data were collected using a cross-sectional design. Study Duration and Location: Data were collected from patients of different ages and gendersattending Ali Omar Ascar hospital, Asabieh, during the period of January 2017 to January 2018. Methodology: A single blood sample was collected from 150 patients and spun at 3000 rpm to obtain serum. The serum samples were analysedto detect anti-Toxoplasma IgG and IgM antibodies using enzyme linked immunosorbant assay (ELISA, BioChec) kit according to manufacturer’s instructions. A self-structured questionnaire was used to obtain information on farm animal’s contact, the process of vegetables washing, meatcooking, Water resource and raw water consumption. Results: The total seroprevalence of toxoplasmosis was 78.6%,out of which IgG and IgM were 68%, and 77.4% respectively. Several risk factors were identified, including daily contact with farm animals (82.6% were +ve, P = .0.01), unfiltered water (61.3% were +ve; P = 0.003). Conclusion: asabieh area showed a high prevalence of toxoplasmosis, and many environmental risk factors associated with the infection as animal hosts, human lifestyle were also identified, that could help to reduce the risk of spreading and transmission of infection among the populations in the future.
