摘要

候鸟可能是公共卫生问题细菌的传播媒介,这些细菌的定植、滞留和排泄介导了这些细菌的传播。本研究旨在确定从鹳的气管(T)和鼻腔(N)样本中获得的细菌的属/种多样性、流行率和共定植指数与通过觅食暴露于点源的关系。采集不同觅食习性(自然栖息地和垃圾填埋场)的白鹳亲本群体87只雏鸟共136个样本(t样84个,n样52个)进行处理。随机选择形态不同的菌落(最多12个/份),用MALDI-TOF-MS进行鉴定。在806株分离菌中,鉴定出398株(56.6%)和305株(43.4%)。检出革兰氏阳性菌和革兰氏阴性菌17属46种,以葡萄球菌(58.0%)和肠球菌(20.5%)最为常见。总分离菌腔中以T(36.7%)和N(34.4%)为主,其次是粪肠球菌(11.1%)和金黄色葡萄球菌(T (6.5%), N(13.4%))。在n个样本中,粪肠杆菌与在垃圾填埋场觅食的亲本鹳的雏鸟显著相关(p = 0.018)。在自然生境中觅食的亲本鹳的雏鸟中,t型样本中ssciuri (p = 0.0034)和M. caseolyticus (p = 0.032)的含量显著高于亲本鹳。在T腔和N腔中,80%以上的细菌之间的共定殖指数为1 ~ 10%,但很少有细菌之间的共定殖指数≥40%。在白鹳雏鸟中最常见的是坐骨棘球菌和粪棘球菌。此外,它们还被其他多样的潜在致病菌高度定植。因此,鹳可能是点源的哨兵,也是细菌在“同一个健康”生态系统中传播的载体。

Nasotracheal Microbiota of Nestlings of Parent White storks with Different Foraging Habits in Spain.

Migratory storks could be vectors of transmission of bacteria of public health concern mediated by the colonization, persistence and excretion of such bacteria. This study aims to determine genera/species diversity, prevalence, and co-colonization indices of bacteria obtained from tracheal (T) and nasal (N) samples from storks in relation to exposure to point sources through foraging. One-hundred and thirty-six samples from 87 nestlings of colonies of parent white storks with different foraging habits (natural habitat and landfills) were obtained (84 T-samples and 52 N-samples) and processed. Morphologically distinct colonies (up to 12/sample) were randomly selected and identified by MALDI-TOF-MS. About 87.2% of the total 806 isolates recovered were identified: 398 from T-samples (56.6%) and 305 from N-samples (43.4%). Among identified isolates, 17 genera and 46 species of Gram-positive and Gram-negative bacteria were detected, Staphylococcus (58.0%) and Enterococcus (20.5%) being the most prevalent genera. S. sciuri was the most prevalent species from T (36.7%) and N (34.4%) cavities of total isolates, followed by E. faecalis (11.1% each from T and N), and S. aureus [T (6.5%), N (13.4%)]. Of N-samples, E. faecium was significantly associated with nestlings of parent storks foraging in landfills (p = 0.018). S. sciuri (p = 0.0034) and M. caseolyticus (p = 0.032) from T-samples were significantly higher among nestlings of parent storks foraging in natural habitats. More than 80% of bacterial species in the T and N cavities showed 1-10% co-colonization indices with one another, but few had ≥ 40% indices. S. sciuri and E. faecalis were the most frequent species identified in the stork nestlings. Moreover, they were highly colonized by other diverse and potentially pathogenic bacteria. Thus, storks could be sentinels of point sources and vehicles of bacterial transmission across the "One Health" ecosystems.

期刊介绍: EcoHealth aims to advance research, practice, and knowledge integration at the interface of ecology and health by publishing high quality research and review articles that address and profile new ideas, developments, and programs. The journal’s scope encompasses research that integrates concepts and theory from many fields of scholarship (including ecological, social and health sciences, and the humanities) and draws upon multiple types of knowledge, including those of relevance to practice and policy. Papers address integrated ecology and health challenges arising in public health, human and veterinary medicine, conservation and ecosystem management, rural and urban development and planning, and other fields that address the social-ecological context of health. The journal is a central platform for fulfilling the mission of the EcoHealth Alliance to strive for sustainable health of people, domestic animals, wildlife, and ecosystems by promoting discovery, understanding, and transdisciplinarity. The journal invites substantial contributions in the following areas: One Health and Conservation Medicine o Integrated research on health of humans, wildlife, livestock and ecosystems o Research and policy in ecology, public health, and agricultural sustainability o Emerging infectious diseases affecting people, wildlife, domestic animals, and plants o Research and practice linking human and animal health and/or social-ecological systems o Anthropogenic environmental change and drivers of disease emergence in humans, wildlife, livestock and ecosystems o Health of humans and animals in relation to terrestrial, freshwater, and marine ecosystems Ecosystem Approaches to Health o Systems thinking and social-ecological systems in relation to health o Transdiiplinary approaches to health, ecosystems and society.
