Avian Influenza a H9N2 Viruses in Morocco, 2018–2019
Low pathogenic H9N2 avian influenza (LPAI H9N2) is considered one of the most important diseases found in poultry (broiler, laying hens, breeding chickens, and turkeys). This infection causes considerable economic losses.

PATHOLOGY OF SPONTANEOUS CASES OF AVIAN TRANSMISSIBLE TUBULONEPHROSIS
著者らは,1962年以来,北アメリカおよびオーストラリアにおいて,aviannephrosis,ncphritisあるいはurcmiaQ名のもとに報告されて来た病と,同類であるとみなされる症例に遭遇したので,これらについて病理組織学的に検索した.検索材料は,3養鶏農家において自然発生した8症例よりなる.病変は,全症例に共通しており,腎と輪尿管の変化が,最も特徴的であった.すなわち,肉眼的には,腎は濶濁腫脹を示し,実質内に,点状または網目状をなした灰白色巣が形成されていた.輪尿管は拡張し,管腔内に白色泥状物質をいれていた.組織病変は,尿細管,集合管に主座し,乳頭管,輸尿管に及んで認められた.すなわち,尿細管上皮の変性,剥離,凝固壊死を発端とし,集合管,乳頭管をも含めて管腔は拡張し ...

Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.
