Morphological Re-Description and 18 S rDNA Sequence Confirmation of the Pinworm Aspiculuris tetraptera (Nematoda, Heteroxynematidae) Infecting the Laboratory Mice Mus musculus

The larvae of Aspiculuris tetraptera were found in the mid-colon of mice within hours of infection. When the colon was divided into 10 equal sections the larvae were mainly found in sections 5, 6 and 7 during the first 6 days of the infection. The worms entered the crypts of Lieberkühn in this region on day 1 and remained there until day 4 or 5. After this time they left the crypts and returned to the lumen of the colon. On day 7 the worms emigrated anteriorly and thereafter were recovered only from the proximal region of the colon (sections 1–4), although in heavier infections a few larvae remained in the mid-colon.The initial establishment site was the same in both Rattus norvegicus and in Apodemus sylvaticus, but an infection with A. tetraptera in the abnormal hosts, R. norvegicus and A. sylvaticus, was characterized by less than 7% of the inoculum becoming established, a slower rate of growth and a wider distribution centering around the preferred site. The small number of established larvae was lost from the rat before day 12 and from A. sylvaticus before day 8, whereas larvae persisted in laboratory mice for a longer period.

Host Evolution

SUMMARYThe molecular phylogeny and morphology of the oxyuroid nematode genusAspiculurisfrom voles and house mice has been examined. Worms collected fromMyodes glareolusin Poland, Eire and the UK are identified asAspiculuris tianjinensis, previously known only from China, while worms fromMus musculusfrom a range of locations in Europe and from laboratory mice, all conformed to the description ofAspiculuris tetraptera. Worms from voles and house mice are not closely related and are not derived from each other, withA. tianjinensisbeing most closely related toAspiculuris dinnikifrom snow voles and to an isolate fromMicrotus longicaudusin the Nearctic. BothA. tianjinensisandA. tetrapteraappear to represent recent radiations within their host groups; in voles, this radiation cannot be more than 2 million years old, while in commensal house mice it is likely to be less than 10 000 years old. The potential ofAspiculurisspp. as markers of host evolution is highlighted.

Aspiculuris Tetraptera

AbstractWild 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. Older mice had fewer larvae and fewer mature worms. The mature worm burdens decreased but relatively slower than the larval burdens. It is suggested that either innate or acquired resistance could account for these observations.

Effect Of Age

Adult animals have been used for most of the previous mammalian temperature selection studies, and relatively few systematic observations have been made with young animals. In this investigation, laboratory mice (Mus musculus), ranging in age from 1 to 84 days, were studied in a horizontal temperature gradient established along a 5-ft copper bar. Despite poorly developed locomotion and cold immobilization, it was shown that the temperature selection response is present at birth. The initially high level of selection appeared to be maintained for about 2 weeks, after which it began to decrease, rapidly at first, and then more slowly until the adult level was reached.
