الإلقاء المستمر لمياه الصرف الصحى في المنطقة الساحلية للبحر المتوسط بمدينة طرابلس و التى تمتد من تاجوراء الى جنزور قد ادى الى حوث تأثيرات سلبية مستمرة على كل من الأحياء المائية و المستهلك بصورة اصبحت ظاهر في تلك المنطقة الساحلية. لقد عرف التلوث الكيميائي المرتبط بتركيبة الصرف الصحى بتأثيره الشديد على جهاز المناعة في الاسماك مما يؤدى الى زيادة في قباليتها للإصابة بالبكتيريا المرضية. في الدراسة الحالية تم عزل أربعة عترات من الميكروب السبحى "ستربتوكوكس" من أسماك المرجان العادى التى تم تجميعها من المنطقة الساحلية لشاطئ طرابلس في المنطقة الممتدة من تاجوراء الى جنزور. توضح النتائج ان ميكروب ستربتوكوكس ايناى (Streptococcus iniae) كان الأكثر شيوعا فى فصلى الصيف و الربيع يليهم على الترتيب ميكروب ستربتوكوكس ديسجلاكتيا (Streptococcus dysgalactiae) أما ميكروب ستربتوكوس فوكى (Streptococcus phocae) فقد كان الأكثر شيوعا في موسم الشتاء. Abstract: The continuous dumping of municipal sewage into the coastal zone of the Mediterranean Sea has been reported to have greater negative impacts on both aquatic animals as well as human consumer. The chemical pollutants in the sewage composites would have deleterious damaging effects on the fish immune system with consequent vulnerability to bacterial invasions. In the current study, four Streptococcal bacterial species were successfully isolated from the Common Pandora fish (Pagellus erythrinus) collected from the coastal zone of Tripoli through the area from Tajourah to Janzour localities. Strept iniae was the most prevalent Streptococci in examined fish during summer and spring seasons followed by Strept dysgalactiae then Enterococus fecalis. Streptococcus phocae was the most prevalently isolated Streptococci from examined fish during the winter season, while Enterococcus fecalis was recorded to be the second on the list.

Abstract Background: Newcastle disease (ND) is a viral disease that affecting many avian species all over the world. Aim: ND has been successfully controlled by the vaccination of commercial poultry in Libya. However, there was a lack of information about the situation of ND in backyard chickens. Therefore, this study determined the prevalence of ND in backyard chickens in different locations of Tripoli. Methods: A total number of 280 cloacal swabs (190 in summer and 90 in winter) and 412 sera were collected from non-vaccinated backyard chicken flocks in different geographical locations within the area of Tripoli namely Qasr Ben Ghashier, Al-Sawani, Souq Al-Gomaa, Tajourah, Ein Zara, and Janzour. Cloacal swabs and sera were tested by real time polymerase chain reaction (PCR) and ELISA, respectively. Results: The prevalence of ND virus (NDV) infection in backyard chickens in different locations of Tripoli during summer and winter was 45% using real-time reverse transcription-PCR. Except in Qasr Ben Ghashier, the prevalence in summer season was significantly higher than in winter (X2 = 46.13, p ≥ 0.00001). ELISA test revealed 218 positive out of 412 tested samples with total prevalence of 53% across the city of Tripoli in all regions. Obviously, Qasr Ben Ghashier had significantly (X2 = 74.09, p ≥ 0.00001) the highest prevalence (82%) of NDV specific antibodies followed by Tajourah (68%). Conclusion: This study demonstrated the situation of ND in backyard chicken highlighting the necessity of a comprehensive vaccination plan for backyard chickens. arabic 14 English 90
