Interspecific hybridization between closely related mammalian species, including various species of the genus Mus, is commonly associated with abnormal growth of the placenta and hybrid foetuses, a phenomenon known as hybrid placental dysplasia (HPD). The role of HPD in speciation is anticipated but still poorly understood. Here, we studied placental and foetal growth in F1 crosses between four...

To investigate the distribution, shape and stainability of the ACTH cells from human, baboon, monkey, cat, dog, rat, mouse, hamster, guinea pig, white-toothed shrew, house musk shrew and mole pituitaries, adjacent tissue sections were immunostained with anti-porcine ACTH1-39 serum and with PAS-ironhematoxylin respectively. Mammalian ACTH cells display two separate morphological appearances :1) ...

We investigate the competition between allele the invasion prospects of rare mutant distorter resident distorter allele are present. The param t complex of the house mouse, one of the be analyzing the invasion chances of rare alleles, w lation results. We show that a new distorter alle at the gamete and at the individual level. In fac rareness advantage if their negative fitness cons Likewise, ...

The rate of recombination is a key genomic parameter that displays considerable variation among taxa. Species comparisons have demonstrated that the rate of evolution in recombination rate is strongly dependent on the physical scale of measurement. Individual recombination hotspots are poorly conserved among closely related taxa, whereas genomic-scale recombination rate variation bears a strong...

Unlike most mammals, most cones in house mouse retina express two opsins, one sensitive to UV-light, and another sensitive to middle-wavelengths. Is the mouse unique, having a single cone type that normally expresses two opsins? Or is the mouse a typical mammal having two cone types, but a species wide mutation results in co-expression of two opsins?

A simple, non-isotopic in-house enzyme-linked immunoabsorbant assay (ELISA) for human growth hormone (GH) was developed. The assay involved using in-house polyclonal anti-GH adsorbed onto 96-well microtitre plates, commercially prepared mouse monoclonal anti-GH, and goat anti-mouse IgG horseradish peroxidase detection system. Results of recovery and parallelism studies ranged from 95%-106% and ...

Studies on island populations of house mice (Mus domesticus) and their viruses reveal insights into viral persistence in isolated communities. We surveyed the ectoparasites, endoparasites, and antiviral antibodies for 11 murine viruses and two bacteria of house mice inhabiting two islands off Australia. House mice on Boullanger Island were seropositive to two viruses, murine cytomegalovirus and...

Hemorrhagic fever with renal syndrome (HFRS) is registered in various geographical regions of the Russian Federation and occupies one leading positions among natural-focal human diseases Russia. The aim study was to assess epidemiological situation on HFRS Rostov Region. Materials methods . Laboratory diagnostics field material (samples from wild rodents) for presence antigens pathogens screeni...

House mice (Mus domesticus) in the Victorian mallee region of southeastern Australia show irregular outbreaks. Changes in reproductive output that could potentially drive changes in mouse numbers were assessed from 1982 to 2000. Litter size in females is positively correlated with body size. When standardized to an average size female, litter size changes seasonally from highest in spring to lo...

In order to determine a practically useful quantitative assay method for tetanus antibody in a large-scale seroepidemiological study, a method combining an in-house ELISA with a particle agglutination test (KPA) was evaluated in comparison with the in vivo mouse neutralization test. Serum samples with mouse neutralization antibody titers 0.01 IU/ml (the minimum protective level) or below showed...
