چکیده

Two RAPD primers and 15 protein biochemical markers were examined to assess the zygosity (hetero/homozygocity) and per cent polymorphisms in monogamous (IM: IF) and triogamous (1M:2F) breeding groups of outbred Mongolian gerbils (Meriones unguiculatus). No polymorphism and heterozygosity were found in RAPD as well as biochemical markers in monogamous groups, whereas both primers in RAPD (%P=55%) and the seven biochemical markers (Alb-1, Es-2, Es-3, Hbb, Idh-1, Pgm-1 and Trf -1) showed polymorphism. On the basis of 15 biochemical markers, genetic variability in terms of per cent polymorphisms (%P=40%), observed heterozygosity (Hob=0.069±0.013), expected heterozygosity (He=0.214±0.277) were observed in triogamous groups. The reproductive performance was severely affected in monogamous groups (colony index, CI=0.33) due to the loss of heterozygosity within the population, whereas the best reproductive performance (CI =0.77) was achieved in heterozygous, triogamous groups.

Determination of Giardia lamblia cyst infective dose for the Mongolian gerbil (Meriones unguiculatus).

The purpose of this study was to determine the 50% infective dose for Giardia lamblia (CDC:0284:1) cysts in Mongolian gerbils (Meriones unguiculatus). The log10 50% infective dose results calculated by probit analysis and the Spearman-Karber method were 2.45 and 2.50, respectively.

Inter‐group associations in Mongolian gerbils: Quantitative evidence from social network analysis

Animals often interact non-randomly with conspecifics, and association preferences can differ across life-history stages to maximize individuals' fitness. Mongolian gerbils (Meriones unguiculatus) are a social rodent that live in highly seasonal habitats and display seasonal fluctuations in population density, growth rate and the size of overlapped home ranges. Nevertheless, whether gerbils mod...

Newly breeding an inbred strain of ischemia-prone Mongolian gerbils and its reproduction and genetic characteristics

The Mongolian gerbil has been a useful laboratory animal in many research fields, especially in ischemia studies. However, due to the variation of the circle of Willis (COW), the ischemic model is unstable and various. To solve this problem, we newly established an inbred strain of gerbils, restricting breeding and keeping to F23. The data on the breeding and growth of the animals are described...
