Characterization of the non-glandular gastric region microbiota in Helicobacter suis-infected versus non-infected pigs identifies a potential role for Fusobacterium gastrosuis in gastric ulceration

Veterinary Research, 2019
Helicobacter suis has been associated with development of gastric ulcers in the non-glandular part of the porcine stomach, possibly by affecting gastric acid secretion and altering the gastric microbiota.

PATHOLOGY OF SPONTANEOUS CASES OF AVIAN TRANSMISSIBLE TUBULONEPHROSIS

The Japanese Journal of Veterinary Science, 1972
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 ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
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.

Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

Animal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...
