New Records of spp. and spp. in Lice Collected from Small Rodents.

Lice are blood-sucking insects that are of medical and veterinary significance as parasites and vectors for various infectious agents. More than half of described blood-sucking lice species are found on rodents. Rodents are important hosts of several and species, and some of these bacteria are characterized as human pathogens in Europe.

Environment-related and host-related factors affecting the occurrence of lice on rodents in Central Europe.

We studied the effects of environment- (habitat, season) and host-related (sex, body mass) factors on the occurrence of four species of lice (Insecta:Phthiraptera:Anoplura) on six rodent species (Rodentia:Muridae). We asked how these factors influence the occurrence of lice on an individual host and whether different rodent-louse associations demonstrate consistent trends in these effects. We found significant effects of at least one environment-related and at least one host-related factor on the louse occurrence in five of six host-louse associations.

Detection of shrew-borne hantavirus in Eurasian pygmy shrew (Sorex minutus) in Central Europe.

Recently, it was found that not only rodents but also shrews are reservoir hosts of hantaviruses. In Central Europe, only Seewis virus, associated with the Eurasian common shrew (Sorex araneus), has been recognized until now. In the present report, tissue samples from shrews belonging to Crocidurinae and Soricinae subfamilies, trapped in Czech Republic, Germany, and Slovakia, were screened for the presence of novel hantaviruses.

Broad geographical distribution and high genetic diversity of shrew-borne Seewis hantavirus in Central Europe.

For a long time hantaviruses were believed to be exclusively rodent-borne pathogens. Recent findings of numerous shrew- and mole-borne hantaviruses raise important questions on their phylogenetic origin. The objective of our study was to prove the presence and distribution of shrew-associated Seewis virus (SWSV) in different Sorex species in Central Europe.

Blood parasites of mound-building mouse, Mus spicilegus Petényi, 1882 (Mammalia, Rodentia).

Mound-building mice, Mus spicilegus, were studied for the blood parasites in Eastern Slovakia, vicinity Kechnec village near Kosice town (Kosická kotlina basin, 21 degrees 14' E, 48 degrees 33' N) during years 2002-2005. Overall, 251 specimens were examined. The parasites were detected using microhematokrit centrifugation technique and on the Giemsa's method stained blood smears and light microscopy.

Anti-Borrelia antibodies in rodents: important hosts in ecology of Lyme disease.

Data presented in this study focuses on the presence of anti-Borrelia antibodies in small mammals from Eastern Slovakia during 2000-2003. The total seropositivity observed was 18.78% in rodents.

Small mammals (Insectivora, Rodentia) as a potential source of chlamydial infection in East Slovakia.

The presence of antibodies against Chlamydophila (Chlamydia) psittaci in small mammals (Insectivora, Rodentia) in the region of East Slovakia are presented. The hosts were caught in several areas of Slovakia in habitats with different levels of anthropogenic disturbance. Research was carried out during 2000-2002.
