Pentatrichomonas hominis in laboratory-bred common marmosets
Trichomonadid protozoa have been found in the intestinal tracts of common marmosets (Callithrix jacchus). However, there is little information available on species identification and the pathogenicity of these trichomonads. In this study, we conducted a fecal survey of a common marmoset colony maintained as laboratory animals in Japan and identified the trichomonad species. Screening using a fe...
متن کاملExercise physiology of wild and random-bred laboratory house mice and their reciprocal hybrids.
We conducted a "common garden" experiment to compare aspects of exercise physiology and voluntary wheel-running behavior in wild and random-bred (i.e., non-inbred) laboratory house mice and their reciprocal crosses. Analysis of covariance indicated that, after effects of body mass and other appropriate covariates (e.g., age at testing) were accounted for, wild (range 2.46-3.30 m/s, n = 12) and ...
متن کاملIndication of a genetic basis of stereotypies in laboratory-bred bank voles (Clethrionomys glareolus).
The development of stereotypies was studied in two successive laboratory-bred generations of bank voles representing F1 (n=248) and F2 (n=270) of an originally wild caught stock. It was shown that the propensity to develop stereotypies under barren housing conditions strongly relates to the same propensity of the parents. Stereotypies were approximately seven times more frequent in the offsprin...
متن کاملMetabolism and Thermoregulation in Crosses between Wild and Random-Bred Laboratory House Mice (Mus domesticus)
We conducted a "common garden" experiment to compare aspects of thermoregulation and metabolism in wild and random-bred laboratory house mice (Mus domesticus) and their reciprocal crosses. Analysis of covariance (ANCOVA) indicated that, after accounting for effects of body mass and other appropriate covariates (e.g., age), wild (N = 12) and hybrid (N = 25) mice together tended to have higher (+...
متن کاملA Review of Mycoplasma in Laboratory Mice
Mycoplasma are small, cell-free bacteria enclosed by a membrane. These bacteria belong to the class of Mollicutes, the order of Mycoplasma tales, and the genus of Mycoplasma. There are more than 100 identified species of mycoplasma. The ratio of cytosine to guanine in its DNA is 23–40% and its genome size is 1350–600 kb. Mycoplasma require cholesterol to grow, and the temperature su...
