Peculiarity of helminthes of synanthropic rodents in urban landscapes of Uzbekistan

This article presents data on the occurrence and diversity of helminthes in rodents inhabiting the urban land-scapes of Uzbekistan; house mouse (Mus musculus), and Norway rat (Rattus norvegicus). In total, sixteen species of parasite were found. The invasion rate (proportion of individuals with parasites) for the Norway rat is 2.4 times as high as that of the house mouse, whilst the intensity of the invasion (number of helminth species per individual) is 2.5 times lower. The overall number of different helminth species found in the house mouse is 1.2 times as high as that of the Norway rat. The invasion rate and intensity are related to the type of residen-tial area, with the highest value for both found in low-rise areas. The level of helminth infection in urban ro-dents was found to vary by season. The peak invasion rate and intensity of invasion were recorded in May, August and December/January. In the case of the house mouse, urban habitats were shown to be more favor-able to the development and distribution of endoparasites than wild habitats.
