“…The main result of this study is clearly that the hybrid susceptibility previously described, both in natural populations of the hybrid zone (Moulia et al 1991;Sage et al 1986) and in introgressed strains from this zone (Derothe et al 2001;Moulia et al 1993), is not observed in experimental hybrids, whatever the cross or generation of hybrids. Note that, while intrasubspecific F2 are as resistant as F1 (i.e.…”

“…A sex-linked difference in resistance of some wildderived strains has been reported, following experimental infections of wild-derived mice with different parasite models (Behnke 1975;Derothe et al 1997Derothe et al , 1999aDerothe et al , 1999bDerothe et al , 2001. Consequently, before the sensu stricto analysis, we tested for a sex-linked difference at two complementary levels in the three sets of experimental infections.…”

“…First, a within-sample analysis was carried out, applying the Mann-Whitney (MW) test between the males and females of each generation of a given cross. Second, a global analysis including all the data of the cross was carried out using a resampling method, the random sampling (RS) test, explained by Derothe et al (1999bDerothe et al ( , 2001. In short, the D variable is defined as the mean of differences between the medians of males and females for each generation of a particular cross.…”

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 than F1, but revealed no increased susceptibility relative to the parents. Intersubspecific F3 and F4 showed the same hybrid vigor as F1. Heterosis contributed most to the resistance, but the differences between intra- and intersubspecific F2 suggested genomic incompatibilities between subspecies. However, the susceptibility did not increase through the recombination process, showing that disruption of co-adaptation does not directly affect resistance. Even if previous studies still support the selective role of parasites in the current hybrid zone, an alternative hypothesis on the origin of hybrid susceptibility is warranted.

“…The higher susceptibility of hybrid genotypes was confirmed in experimental infections with the mouse nematode Aspicularis teraptera of artificial hybrids between these two subspecies, thus confirming the genetic nature of the hybrid susceptibility (Moulia et al, 1993), and suggesting a breakdown of the coadaptation of immunity genes (Moulia et al, 1996). Interestingly, hybrids proved to be highly susceptible to some, but not all kinds of parasites (Derothe et al, 1999a(Derothe et al, , 2001) which could reflect diverse host/parasite coevolutionary histories, or the involvement of different immune pathways in the reaction to various infections (Porcherie, unpublished results). However, other characters might be suggestive of hybrid vigor rather than hybrid depression between these subspecies.…”

Comparative genomics has developed by comparison of distantly related genomes, for which the link between the reported evolutionary changes and species development/physiology/ecology is not obvious. It is argued that the mouse (genus Mus) is an optimal model for microevolutionary genomics in vertebrates. This is because the mouse genome sequence, physical and genetic map have been completed, because mouse genetics, morpho-anatomy, pathology, behavior and ecology are well-studied, and because the Mus genus is a diverse, well- documented taxon, allowing comparative studies at the level of individual, population, subspecies, and species. The potential of the interaction between mouse genome and mouse biodiversity is illustrated by recent studies of speciation in the house mouse Mus musculus, and studies about the evolution of isochores, the peculiar pattern of GC-content variation across mammalian genomes.

“…bactrianus and their genetic, behavioral and ecological characteristics are well differentiated among the subspecies. With regards to the hygienic-genetic point of view, the most important factor is the subspecies differences in sensitivity to exogenous and/or endogenous infectious microorganisms or parasites causing emerging and reemerging infectious diseases mediated by the mouse (Sage et al, 1986;Sangster et al, 1993;1998;Derothe et al, 1999;2001;Brinton and Perelygin, 2003). To identify the subspecies, we have developed an easy and efficient diagnostic method, which is the utilization of SNPs in highly mutable areas in the mtDNA D-loop region.…”

House mouse (Mus musculus) is one of the perilous animal vectors for imported zoonosis such as a lymphocytic choriomeningitis (LCMV) infectious disease, and probably unknown emerging and/or re-emerging infectious diseases as well. It is necessary to prevent such diseases by regular surveys for behavioral trends of these allochthonous mice. However, such a trial has never been attempted in Japan. From 1998 to 2002, we analyzed partial sequences of the D-loop region in mtDNA, which provides powerful diagnostic SNPs for subspecies identification in the Mus musculus species, from 301 individuals of mice collected in 23 international bays or airports in Japan. We found that invasion of many allochthonous mice, which were identified as European subspecies, Mus musculus domesticus, occurred in Tokyo metropolitan coastal area. Based on the evidence, we warn that extensive invasion of allochthonous mice has occurred recently and, therefore, the risk of emerging and/or re-emerging infectious diseases invasion might be high in Tokyo metropolitan area.
