Scanning and Transmission Electron Microscopic Observations of Eperythrozoon ovis (E. ovis)
The Japanese Journal of Veterinary Science, 1982 Eperythrozoon ovis 人工感染緬羊の血液と骨髄液の電顕学的観察により, 本虫体は大きさ 0.2-0.6μm の桿状およびリング状の寄生体で単層の限界膜を有し, 内部にリボゾームに類似した顆粒を密に含有することを知った. また, 虫体の周辺部には糸状構造物を持ち,それを介して付着する像を認めた. 骨髄液の検索により, E. ovis は骨髄で増殖して赤芽球の時期からすでに寄生することが確認された.

Medical and Veterinary Entomology, EarlyView.Four Afrotropical Culicoides species are recorded in Mauritius with suspected or historically involvement in BTV and EHDV transmission. All species were distributed all over the island. While intra‐specific morphological variations were detected, genetic analyses did not reveal any cryptic diversity. Abstract Viruses transmitted by biting midge species

Medical and Veterinary Entomology, EarlyView.A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

Veterinary Ophthalmology, EarlyView.ABSTRACT Objective To investigate the antimicrobial effect of 275 nm wavelength ultraviolet C (UV‐C) light on M. bovis using an affordable, broadly available modified handheld device and to determine if photoreactivation plays a role in bacterial resistance to UV‐C. Methods UV‐C therapy (UVCT) was evaluated in vitro using triplicates of 3 M.

Mammal Review, Volume 56, Issue 1, March 2026.Black bears as apex predators. American black bears can (1) produce top‐down effects on ungulates equal to or exceeding those of typical apex predators and (2) modify the spatiotemporal behaviour of other carnivores, including pumas and coyotes. We argue that the term ‘apex predator’ is highly context dependent and not a species‐wide status.
