Parasite hybrid zones resulting from host secondary contact have never been described in nature although parasite hybridization is well known and secondary contact should affect them similarly to free-living organisms. When host populations are isolated, diverge and recontact, intimate parasites (host specific, direct life cycle) carried during isolation will also meet and so may form parasite hybrid zones. If so, we hypothesize these should be narrower than the host's hybrid zone as shorter parasite generation time allows potentially higher divergence. We investigate multilocus genetics of two parasites across the European house mouse hybrid zone. We find each host taxon harbours its own parasite taxa. These also hybridize: Parasite hybrid zones are significantly narrower than the host's. Here, we show a host hybrid zone is a suture zone for a subset of its parasite community and highlight the potential of such systems as windows on the evolutionary processes of host-parasite interactions and recombinant pathogen emergence.

Syphacia obvelata is a common gastro-intestinal parasitic nematode of the house mouse (Mus musculus), a prime model rodent species. Investigations of the genetic structure, variability of parasite populations and other biological aspects of this host-parasite system are limited due to the lack of genetic resources for S. obvelata. To fill this gap, we developed a set of microsatellite markers for S. obvelata, using a 454 pyrosequencing approach. We designed three multiplex panels allowing genotyping of 10 polymorphic loci and scrutinized them on 42 samples from two different regions inhabited by two different house mouse subspecies (Mus musculus musculus and M. m. domesticus). The numbers of alleles ranged from 2 to 6 with mean observed heterozygosities 0.1476 and 0.2095 for domesticus and musculus worms, respectively. The described markers will facilitate further studies on population biology and co-evolution of this host-parasite system.

PCR diagnostics detected 100% prevalence of Helicobacter in 425 wild house mice (Mus musculus) from across central Europe. Of seven species identified, the five most frequent were Helicobacter rodentium (78%), H. typhlonius (53%), H. hepaticus (41%), H. bilis (30%), and H. muridarum (1%). Double infections were more common (42%) than single (30%) and triple (21%) infections. Wild house mice could be considered potential reservoirs of Helicobacter strains for both humans and other vertebrates.
