| oogenesis and egg-shell formation in aspiculuris tetraptera schulz (nematoda: oxyuroidea). | the ovary of aspiculuris tetraptera has a prominent terminal cap cell. this is considered to be part of the ovarian epithelium. oogonia detach from the short rachis and increase in size from 6 to 60 microns; accumulating hyaline granules, shell granules and glycogen. the hyaline granules persist in the eff cytoplasm after shell formation has been completed and are considered to be lipoprotein yolk. the shell granules contribute to the non-chitin fraction of the chitinous layer. a classification ... | 1979 | 471533 |
| the structure of the egg-shell of aspiculuris tetraptera schulz (nematoda: oxyuroidea). | the egg of aspiculuris tetraptera is an ellipsoid measuring 93 x 40 microns. the shell consists of 5 layers: the external uterine layer, internal uterine layer, vitelline layer, chitinous layer and the lipid layer. this nomenclature is based upon the formation and histochemistry of the shell layers. the internal uterine layer contains a system of interconnecting spaces, partly filled by uterine secretion, which open to the exterior of the egg via breaks in the external uterine layer. the surface ... | 1979 | 471534 |

| comparison of traditional and pcr methods during screening for and confirmation of aspiculuris tetraptera in a mouse facility. | pinworm detection in laboratory rodents typically is accomplished by using the tape test or various modifications of fecal flotation test to detect eggs. direct examination of intestinal contents remains the 'gold standard' for pinworm detection, with the limitation of euthanasia of animals. here, we compare traditional and real-time pcr methodologies during screening for and confirming the presence of aspiculuris tetraptera. two sets of pooled fecal samples collected from each of 521 microisola ... | 2011 | 22330785 |
| microbiological survey of mice (mus musculus) purchased from commercial pet shops in kanagawa and tokyo, japan. | information regarding the prevalence of infectious agents in mice in pet shops in japan is scarce. this information is particularly useful for minimizing the risk of potential transmission of infections to laboratory mice. therefore, we surveyed infectious agents in mice from pet shops in kanagawa and tokyo, japan. the survey was conducted in 28 mice from 5 pet shops to screen for 47 items (17 viruses, 22 bacteria and fungi, 10 parasites) using culture tests, serology, pcr, and microscopy. the m ... | 2014 | 25502736 |
| parasites and invasions: changes in gastrointestinal helminth assemblages in invasive and native rodents in senegal. | understanding why some exotic species become widespread and abundant in their colonised range is a fundamental issue that still needs to be addressed. among many hypotheses, newly established host populations may benefit from a parasite loss ("enemy release" hypothesis) through impoverishment of their original parasite communities or reduced infection levels. moreover, the fitness of competing native hosts may be negatively affected by the acquisition of exotic taxa from invaders ("parasite spil ... | 2016 | 27670366 |
| guidance regarding sample collection and refinement of fecal flotation exam for the isolation of aspiculuris tetraptera. | aspiculuris tetraptera continues to be a problem in rodent vivaria, in part due to difficulties in parasite detection. although pcr testing is highly sensitive, it is expensive and does not always provide immediate results. consequently, many institutions rely on passive fecal flotation as a quick inhouse exam for diagnosing a. tetraptera infections. to increase the sensitivity of this test, we examined multiple parameters to determine the optimal test protocol. a 30-min soaking period prior to ... | 2016 | 27657708 |
