| aspiculuris tetraptera in wild mus musculus. age resistance and acquired immunity. | wild house mice, naturally infected with aspiculuris tetraptera were segregated according to their weight into six age groups. the prevalence of infection and the mean worm burden of these mice were studied in the different age groups. the overall prevalence of infection was high (57% or more) in all the groups except the youngest. mice acquired larvae soon after weaning; the highest larval burdens were reached in juvenile mice and the highest mature worm burdens, a group later, in mature mice. ... | 1976 | 1033219 |
| aspiculuris tetraptera in wild mus musculus. the prevalence of infection in male and female mice. | a survey was carried out of the levels of infection with aspiculuris tetraptera and syphacia obvelata in a wild house mouse population living in the charles clore small mammals pavilion at the london zoo in regent's park. the extent of infection with a. tetraptera is analysed according to the sex of the host. it is shown that the prevalence of infection was greater in male than in female mice and frequency distribution studies suggest that this is not only because fewer female mice become infect ... | 1975 | 1171137 |

| induction of lymphoma in athymic mice: a model for study of the human disease. | a murine lymphoma, designated l1, was produced in immunologically deficient nude mice after chronic antigenic stimulation by infection with the pinworms aspiculuris tetraptera and syphacia obvelata. in vivo, l1 involves primarily the spleen and lymph nodes, with infiltration of liver, kidney, and bone marrow also observed. it is characterized by large clusters of b cells and null cells, and by rare t cells. the lymphoma cells express murine leukemia virus antigens (gp70 and p30) on the surface. ... | 1980 | 6254048 |
| hybrid vigour against parasites in interspecific crosses between two mice species. | the resistance and susceptibility to the intestinal pinworm aspiculuris tetraptera, a natural parasite of the house mouse mus musculus, is experimentally analysed using both the f1 from wild-type mice of the two subspecies (m. m. domesticus and m. m. musculus) and the f1 from different laboratory inbred mice. the results show that: (i) the f1 from wild-type mice harbour a lower parasite load than the parental mice, suggesting a phenomenon of hybrid vigour; and (ii) the f1 from inbred mice harbou ... | 1995 | 7852098 |
| experimental evidence of genetic determinism in high susceptibility to intestinal pinworm infection in mice: a hybrid zone model. | in the hybrid zone of the two mouse subspecies mus musculus musculus and mus musculus domesticus, mice with hybrid genotypes harbour, on the average, more helminth parasites (cestodes and nematodes) than mice of the two parental taxa. in order to determine the roles played by genetic parameters in this phenomenon, mice with recombined and parental genotypes were experimentally infected with the intestinal pinworm aspiculuris tetraptera, a natural parasite of the house mouse. the results showed t ... | 1993 | 8316436 |
| comparison between patterns of pinworm infection (aspiculuris tetraptera) in wild and laboratory strains of mice, mus musculus. | sixteen laboratory and 7 wild-derived strains of mice were infected with the pinworm aspiculuris tetraptera in order to compare their resistance levels estimated by the intestinal parasite loads. it appears that (i) in 4 strains out of 23, females and males harbour different parasite loads; (ii) wild and laboratory mice display a broad range of infection levels when compared independently; (iii) the laboratory strains are more resistant than the wild ones. we suggest that (i) compared to sex, th ... | 1997 | 9229248 |
| evaluation of coinfection with pinworms (aspiculuris tetraptera, dentostomella translucida, and syphacia obvelata) in gerbils and mice. | mongolian gerbils (meriones unguiculatus) naturally infected with the nematode dentostomella translucida and mice (mus musculus) that were either pinworm-free or harboring either or both aspiculuris tetraptera and syphacia abvelata were crossinfected experimentally with these nematode species. gerbils were susceptible to infections by s. obvelata and a. tetraptera from mice, whereas mice were resistant to infection by d. translucida from gerbils. the data presented are the first regarding coinfe ... | 2003 | 12906402 |

| recombination does not generate pinworm susceptibility during experimental crosses between two mouse subspecies. | the susceptibility to aspiculuris tetraptera of european mus musculus hybrids is thought to reflect the disruption of genomic co-adaptation through recombination of the parental genomes. here, we compared the susceptibility to this parasite between parents and experimental hybrids (intersubspecific until f4, intrasubspecific f1, f2) to clarify the contributions of heterosis and subspecies incompatibility. f1 showed hybrid vigor. unlike intrasubspecific f2, intersubspecific f2 were less resistant ... | 2004 | 15197582 |

| anthelmintic activity of croton zehntneri and lippia sidoides essential oils. | because of the development of anthelmintic resistant populations, the search for new drugs is essential to maintain the productivity of small ruminants. the aim of this study was to evaluate the anthelmintic activity of croton zehntneri and lippia sidoides essential oils and their major constituents, anethole and thymol. the effects of these oils and their constituents were determined by in vitro assays with the eggs and larvae of the sheep gastrointestinal nematode haemonchus contortus. the two ... | 2007 | 17629623 |
| 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 |
| bank voles (myodes glareolus) and house mice (mus musculus musculus; m. m. domesticus) in europe are each parasitized by their own distinct species of aspiculuris (nematoda, oxyurida). | the molecular phylogeny and morphology of the oxyuroid nematode genus aspiculuris from voles and house mice has been examined. worms collected from myodes glareolus in poland, eire and the uk are identified as aspiculuris tianjinensis, previously known only from china, while worms from mus musculus from a range of locations in europe and from laboratory mice, all conformed to the description of aspiculuris tetraptera. worms from voles and house mice are not closely related and are not derived fr ... | 2015 | 26302680 |
