Proteomic analysis of the pinworm Syphacia muris (Nematoda: Oxyuridae), a parasite of laboratory rats
2012
Syphacia muris (Nematoda: Oxyuridae) is a ubiquitous nematode that commonly infects rats in the laboratory which can interfere in the development of biological assays. The somatic extract of S. muris adults collected from infected rats was investigated using a proteomic approach. A shot-gun liquid chromatography/tandem mass spectrometry procedure was used. We used the MASCOT search engine (Matrix-Science) and ProteinPilot software v2.0 (Applied Biosystems) for the database search. A total of 359 proteins were accurately identified from the worms. The largest protein families consisted of metabolic enzymes and those involved in the nucleic metabolism and cell cycle. Proteins of transmembrane…
Research trends in the journal Hormones and Behavior (1987-2000).
2003
As a continuation of the study carried out by Svare more than 15 years ago (Horm. Behav. 22 (1988), 139) and to determine the tendencies of the evolution of behavioral endocrinology since then, our aim was to extend his work until 2000, assuming that the journal Hormones and Behavior would be representative of the field at large. To study this 14-year period and compare it with Svare's data, we kept the same criteria and categories, behavioral patterns, and species. Our results show that "sexual behavior" in "rodents" is still the most extensive field studied by behavioral endocrinologists, although frequency of other topics is increasing, above all "aggressive and emotional responses," and…
Précisions sur la localité-type du campagnol des Pyrénées Microtus (Terricola) pyrenaicus (de Sélys Lonchamps, 1847) (Arvicolinae, Rodentia).
2010
2 pages; National audience; L'objectif de cette note est de préciser aussi exactement que possible la localité-type du campagnol des Pyrénées Microtus (Terricola) pyrenaicus (de Sélys Lonchamps, 1847) : montagnes des Pyrénées, Pic du Midi de Bigorre, à une grande altitude (Hautes-Pyrénées, France).
Analyse comparée des critères de la première molaire inférieure entre différentes populations du campagnol basque Microtus (Terricola) lusitanicus (G…
2009
9 pages; National audience; L'objectif de cette étude est l'analyse comparée des critères de la première molaire inférieure (M1) entre sept groupes géographiques du campagnol basque Microtus (Terricola) lusitanicus (Gerbe, 1879) répartis sur l'ensemble de l'aire de répartition de l'espèce. Le principal résultat est la différenciation du groupe des Pyrénées françaises, caractérisé en particulier par un développement réduit de la partie antérieure de la M1. Dans les groupes géographiques ibériques, des différences morphologiques sont trouvées pour chaque critère, mais ces différences sont moins significatives que celles observées pour le groupe des Pyrénées françaises. Le statut sub-spécifiqu…

Experimental Infection of Voles with Francisella tularensis Indicates Their Amplification Role in Tularemia Outbreaks
2014
Tularemia outbreaks in humans have been linked to fluctuations in rodent population density, but the mode of bacterial maintenance in nature is unclear. Here we report on an experiment to investigate the pathogenesis of Francisella tularensis infection in wild rodents, and thereby assess their potential to spread the bacterium. We infected 20 field voles (Microtus agrestis) and 12 bank voles (Myodes glareolus) with a strain of F. tularensis ssp. holarctica isolated from a human patient. Upon euthanasia or death, voles were necropsied and specimens collected for histological assessment and identification of bacteria by immunohistology and PCR. Bacterial excretion and a rapid lethal clinical …
Ecological Analysis of the Helminth Community of Microtus lusitanicus (Gerbe, 1879) (Rodentia) in Asturias (NW Spain)
2021
Simple Summary The Lusitanian pine vole is an endemic rodent of the Iberian Peninsula, which has a burrowing behaviour and prefers to live underground. It feeds on bark and roots causing severe damage to trees. In Asturias (NW Spain), this species is considered a pest causing economic losses in apple orchards, damaging the tree, and sometimes even causing its death. With the aim to shed light on the helminth community of this rodent pest species and to elucidate which intrinsic and extrinsic factors affect its helminth species, a faunistic-ecological study was carried out. For this purpose, our own collection of 710 voles from several orchards of various locations in Asturias was used. The …
Rodent Animal Research in UTx
2019
The rodents, mouse, and rat represent well-characterized animal sources for basic research in any field of biological sciences. The animals are cheap compared to other type of animals, easy to husbandry, and are extremely well characterized from genetic and physiology point of views, especially when it comes to immunological and reproductive aspects. Availability of gene-modified strains, easy embryo transfer, and the accessibility of specific recombinant proteins and monoclonal antibodies are further advantages. Hence, the first experiments done in the modern era of uterus transplantation used mouse and rat as the main animal models. In this chapter, we describe important key steps of the …
Serological evidence for Borna disease virus infection in humans, wild rodents and other vertebrates in Finland
2005
Abstract Background Borna disease virus (BDV) can infect many vertebrate species, including humans. BDV infection may lead to meningoencephalomyelitis in animals. An association with human neuropsychiatric diseases has been reported, but the causal relationship between BDV and human disease remains unclear. Objectives and study design To find out whether BDV is present in Finland and to look for a potential reservoir, we examined a large panel of blood samples from different vertebrate species with immunofluorescence assay. Samples from horses, cats, dogs, sheep, cattle, large predators, grouse, wild rodents and humans were included. Most positive results were confirmed by other specific me…
Distribution and phenotype of rotavirus-specific B cells induced during the antigen-driven primary response to 2/6 virus-like particles administered …
2007
AbstractSelection of mucosal sites is an important step in mucosal vaccine development. The intrarectal (IR) route represents an alternative to the oral route of immunization; nevertheless, immune responses induced by this route are not well defined. Here, we studied the early primary B cell response (induction, homing, and phenotype) induced by IR immunization with rotavirus (RV)-2/6 virus-like particles (VLP). Using flow cytometry, we traced RV-specific B cells in different lymphoid tissues and analyzed the expression of α4β7 and CCR9, which are important receptors for homing to the gut, as well as CD5, a marker expressed by B1-a cells, which are a major source of natural antibodies. We o…
