| Summary, etc. | Poor water quality is considered the most critical predisposing factor for disease eruptions in aquaculture facilities. Abrupt decrease or fluctuation in water temperature is a detrimental factor in occurrence of some low temperature dependent microbes. The ubiquitous pathogen Pseudomonas fluorescens and the saprotrophic water mold Saprolegnia parasitica are ideal examples for this disease pathway. In the current study, the two ubiquitous microbes were isolated from Nile tilapias at an acre size earthen pond that were overstocked with more than 25,000 fingerlings during an episode of mass mortalities at mid-February 2023. The peak of mass mortalities occurred after heavy rains and wind storms that hit the country during this time of the year. Most of the dead and moribund fishes were suffering from generalized skin ulcers, fin rot, gill congestion and cottony wool like hyphae intimately attached to skin ulcers and fins. Internally, almost all internal organs including kidney, spleen and liver were congested. Histopathological examination of affected fish showed hyalinization and necrosis of fin tissues together with inflammatory cells infiltration. Moreover, fungal hyphae were detected within the muscle bundles. The final identity of the retrieved Pseudomonas <br/>fluorescens was confirmed using 16S rRNA gene sequence analysis, while <br/>Saprolegnia parasitica isolates were confirmed using ITS rDNA gene sequence analysis. All supportive accession numbers for retrieved isolates were published through the Genbank official website. |

| Summary, etc. | يعتبر سوء جودة المياه من أهم العوامل التي تسببتفشي الأمراض في أحواض تربية الأحياء المائية و يعد الانخفاض المفاجئ أو التقلب في درجة حرارة الماء عاملاً ضارًا في حدوث بعض الأمراض الناتجة عن درجات الحرارة المنخفضة و يعد المرض السائدPseudomonas Fluorescensوعفن الماء الريميSaprolegnia parasiticaمن الأمثلة المثالية لمسار هذا المرض. في الدراسة الحالية، تم عزل الميكروبين الموجودين في أسماك البلطي النيلي في حوض طيني بحجم فدان كانت مكتظة بأكثر من 25000 من الزريعة خلال فترة النفوق الجماعي في منتصف فبراير 2023. وقد حدثت ذروة النفوق الجماعي بعد العواصف والرياح وهطول أمطار غزيرةالتي تضرب البلاد في هذا الوقت من العام. وكانت معظم الأسماك الميتة والمحتضرة تعاني من تقرحات جلدية شديدة، وتعفن الزعانف، واحتقان الخياشيم، وخيوط فطرية تشبه قطع القطن ملتصقة بشكل وثيق بتقرحات الجلد والزعانف. داخليًا، وكانت جميع الأعضاء الداخلية تقريبًا بما في ذلك الكلى والطحال والكبد محتقنة. أظهر الفحص النسيجي المرضي للأسماك المصابة تبلور ونخر أنسجة الزعانف مع ارتشاح الخلايا الالتهابية وعلاوة على ذلك، تم اكتشاف تجمعات فطرية داخل الحزم العضلية. تم تأكيد الهوية النهائية المستردةPseudomonas Fluorescensباستخدام تحليل تسلسل الجينات16S rRNA، في حين تم تأكيد عزلاتSaprolegnia parasiticaباستخدام تحليل تسلسل الجينات ITS rDNA تم نشر جميع أرقام الانضمام الداعمة للعزلات المستردة من خلال موقع Genbank الرسمي. |
