On the basis of our 2011 microbiological monitoring tests, we report here the current microbiological status of mice and rats housed in experimental facilities in Japan. We tested more than 14,000 mice, 6,000 serum samples, 500 fecal or cecal samples, and 200 lung samples from 3,549 mouse facilities within Japanese universities and institutes (U/I), pharmaceutical companies and contract researc...
Parasites are considered to be an important selective force in host evolution but ecological studies of host-parasite systems are usually short-term providing only snap-shots of what may be dynamic systems. We have conducted four surveys of helminths of bank voles at three ecologically similar woodland sites in NE Poland, spaced over a period of 11 years, to assess the relative importance of te...
Seasonal fluctuations in the prevalence and abundance of infection with intestinal helminths were studied in Apodemus sylvaticus (wood mouse, n = 399), from three contrasting habitats in southern England, to test the hypothesis that both intrinsic (host sex, age) and extrinsic (season, site) factors influence parasite species richness and abundance. Five species of helminths were recovered but ...
به منظور شناخت تنوع آلودگیهای کرمی دستگاه گوارش موشهای شهرستان کاشان 120 سر موش ووحشی و خانگی از مناطق کویری و شهری کاشان با تله زنده گیر ، صید گردید و پس از بیهوشی و شناسایی ، تشریح و کرمهای دستگاه گوارش جدا گردید و پس از شمارش و فیکساسیون درفرمالین 10 درصد و رنگ آمیزی با کلیدهای تشخیص شناسلیی گردید . نتایج تحقیق نشان داد 68 سر موش (7/56 درصد) آلوده به کرمهای روده ای بودند و مجموعاً 6 گونه نمات...
background: in this paper, paleoparasitological findings from rodent excrements ob-tained from chehrabad salt mine archeological site located in northwest of iran are demonstrated and discussed. methods : chehrabad salt mine archeological site located in northwest of iran, dated to the achaemenid (mid 1st mill. bce) and to sassanid (3rd cent. - 7th cent. ce) period, is a unique study area to in...
BACKGROUND Rats live in close proximity to human populations. Feral rodents are known to transmit diseases and act as reservoir hosts to many zoonotic parasites that pose health risks to humans. The aim of this study is to investigate endoparasitic infections in commensal rats and shrews caught in traditional wet markets in Taichung City, Taiwan. METHODS A total of 51 commensal wild rodents a...
Helminth infections were studied in bank voles (Myodes glareolus) from 3 woodland sites in N.E. Poland in the late summers of 1999 and 2002, to assess the temporal stability of derived statistics describing the regional helminth fauna and component community structure, and spatial influence on the latter. Regional helminth fauna changed dramatically between the two years, primarily due to a fal...
