Datasets from which wildlife contact networks of epidemiological importance can be inferred are becoming increasingly common. A largely unexplored facet of these data is finding evidence of spatial constraints on who has contact with whom, despite theoretical epidemiologists having long realized spatial constraints can play a critical role in infectious disease dynamics. A graph dissimilarity m...

The National Park “Smolny” is a large forest area, located in the center of European Russia. helminth fauna myomorph rodents was studied for first time within 2018–2020. Rodents were examined by method complete helminthological dissection. A total 30 species parasites recorded 11 rodent species: 6 trematodes, cestodes and 13 nematodes. trematode Plagiorchis maculosus (Rudolphi, 1802) found Clet...

BACKGROUND In this study the concentration of lysozyme in blood plasma of Microtus agrestis, Clethrinomys glareolus, Apodemus sylvaticus, BK rats and outbred white mice before and after infection with culture forms of Trypanosoma microti, T, evotomys, T. grosi, T. lewisi and T. musculi respectively was measured. METHODS Blood samples of rodents, Microtus agrestis, Clethrionomys glareolus, Apo...

It has long been hypothesized that chromosomal rearrangements play a central role in different evolutionary processes, particularly in speciation and adaptation. Interchromosomal rearrangements have been extensively mapped using chromosome painting. However, intrachromosomal rearrangements have only been described using molecular cytogenetics in a limited number of mammals, including a few rode...

Aim: To evaluate the phytochemical constituents and the aphrodisiac potential of the aqueous extract of Fadogia agrestis (Rubiaceae) stem in male albino rats. Methods: The aqueous stem extract of the plant was screened for phytochemical constituents. Male rats were orally dosed with 18 mg/kg, 50 mg/kg and 100 mg/kg body weight, respectively, of the extract at 24 h intervals and their sexual beh...

BACKGROUND Antimicrobial resistance (AMR) is the most significant threat to global public health and ascertaining the role wild birds play in the epidemiology of resistance is critically important. This study investigated the prevalence of AMR Gram-negative bacteria among long-distance migratory East Canadian High Arctic (ECHA) light-bellied Brent geese found wintering on the east coast of Irel...

Background: The effects of aqueous extract of Fadogia agrestis stem at the doses of 18, 36, and 72 mg/kg body weight on alloxan-induced toxicity was investigated in Wistar rats. Methods: In total, 35 rats of both sexes (132.80±7.22g) were randomized into five groups (A-E): animals in group A received 0.5 ml of distilled water orally on daily basis for 15 days while the alloxanized rats in gr...

A comparative study was performed on 12 species of the genus Veronica L. (Plantaginaceae sensu APG 2003, formerly Scrophulariaceae) namely Veronica persica, V. bachofenii, V. urticifolia, V. agrestis, V. austriaca, V. chamaedrys, V. officinalis, V. orchidea, V. spicata, V. beccabunga, V. hederifolia, V. prostrata. In these species we have determined the aucubin and catalpol content by using a H...

Members of the microtine species are probably reflex ovulators. The prairie vole, Microtus ochrogaster (Richmond & Conway, 1969), the meadow vole, M. pennsylvanicus (Clulow & Mallory, 1970), the levant vole, M. guentheri (Bodenheimer & Sulman, 1946), the Californian vole, M. californicus (Greenwald, 1956), and the montane vole, Microtus montanus (Gray, Davis, Zerylnick & Dewsbury, 1974) have al...
