“…Adult males, as opposed to females, were responsible for the majority of the nematode transmission (Ferrari et al 2004). H. polygyrus represented the most common helminth with population prevalences reaching 85 % (Rosso et al 2002 ;Ferrari, 2005).…”

S U M M A R YFree-living animals are usually inhabited by a community of parasitic species that can interact with each other and alter both host susceptibility and parasite transmission. In this study we tested the prediction that an increase in the gastrointestinal nematode Heligmosomoides polygyrus would increase the infestation of the tick Ixodes ricinus, in free-living yellownecked mice, Apodemus flavicollis. An extensive cross-sectional trapping survey identified a negative relationship between H. polygyrus and I. ricinus counter to the prediction. An experimental reduction of the nematode infection through anthelmintic treatment resulted in an increase in tick infestation, suggesting that this negative association was one of cause and effect. Host characteristics (breeding condition and age) and habitat variables also contributed to affect tick infestation. While these results were counter to the prediction, they still support the hypothesis that interactions between parasite species can shape parasite community dynamics in natural systems. Laboratory models may act differently from natural populations and the mechanism generating the negative association is discussed.

“…Rodentolepis fraterna, which was once considered synonymous with Hymenolepis nana, was found by Kataranovski et al (2008) in Serbian house mice. Its congener, R. straminea, primarily parasitizes striped fi eld and yellow-necked mice, but also infects the forest dormouse according to Bulgarian data (Genov, 1984). Paranoplocephala omphalodes was noted in a large number of rodent species in France, including the bank, common and European snow voles, two Apodemus species, and several Pitymys voles (Feliu et al, 1997).…”

“…Furthermore, nematodes are also the dominant helminth group in A. agrarius with regards to prevalence and mean abundance, the key difference being the species present. The stenoxenous H. travassosi is characteristic of the hamster, and is substituted by the congeneric species H. polygyrus in Apodemus species (Genov, 1984). Considering the diet of the European hamster, the indisputable dominance of nematodes is unsurprising.…”

“…This procedure was used both for adult tapeworms and their larval stages. Identifi cation of species was carried out by using identifi cation keys, provided by Ryzhikov et al (1978, 1979) and Genov (1984. For quantitative analysis, prevalence (P %) and mean abundance (A) were calculated according to Bush et al (1997).…”

“…Consequently, data on the topic is very scarce, which is an unfortunate situation considering the signifi cance of small mammals such as rodents and insectivores in the dissemination and maintenance of parasites in natural and urban environments. This becomes even more apparent through comparison with information available from other European countries where these studies are abundant, such as Hungary (Mészáros, 2001), Lithuania (Grikienienė, 2005;Binkienė, 2006), Poland (Behnke et al, 2001(Behnke et al, , 2008a(Behnke et al, , 2008b and Italy (Ferrari et al, 2004) to name just a few.…”

SummaryA total of 359 European hamsters (Cricetus cricetus) captured at four localities in Vojvodina Province were examined for the presence of helminths. The majority of the captured animals (88 %) were infected with nematode species Heligmosomoides travassosi and six species of cestodes (Hymenolepis diminuta, Rodentolepis fraterna, R. straminea, Paranoplocephala omphalodes and Mesocestoides sp. -in larval stages). Nematodes were the dominant group. The dominant cestode species was H. diminuta. All of the tapeworm species reported here represent new fi ndings for the European hamster in Serbia. The tapeworms H. diminuta and Mesocestoides sp. are capable of infecting humans and causing pathological symptoms, making the hamster a carrier of zoonoses and a potential threat to public health. In order to uncover the full range of helminths utilizing the European hamster as a host in Serbia and understanding the scope of its zoonotic potential, further research on the subject must be carried out.

Spacing behaviors and spatial recruitment of a wild rodent in response to parasitism

Abstract. Host spacing may benefit the parasites (e.g., enhance parasite transmission) or the hosts (e.g., reduce host infection), with profound consequences in epidemiology and host-parasite dynamics. In this study, we tested parasitism effects of intestinal nematodes on spacing behaviors and spatial recruitment of the Taiwan field mouse (Apodemus semotus). We tracked the locations of resident mice for 84% of the host population, with half of them experimentally reduced of their parasitic infection. We interpolated geo-tagged data on parasite egg counts of the resident mice to create an infection risk landscape and extracted the risks to the locations of newly recruited mice. We performed parentage analysis to identify mother-offspring pairs, which allowed us to test whether in situ recruits moved toward lower-risk areas during natal dispersal. We found that the less-infected mice became spatially aggregated compared to the more heavily infected, and the juvenile recruits occurred preferentially in lower-risk areas compared to the landscape, the residents, and their natal places. The spatial aggregation of less-infected resident mice and the association of juvenile recruits with lower-risk areas could hinder parasite transmission. This study provided some empirical support for a potential link between host recruitment process and parasitism risks.
