Demodex spp. [Acari: Demodecidae] in brown rat [Rodentia: Muridae] in Poland

The study on the demodecid fauna of the brown rat (Rattus norvegicus) revealed the presence of three species: Demodex nanus, D. norvegicus, and D. ratti, all three new for the fauna of Poland

Recent data on Demodex rosus Bukva, Vitovec et Vlcek, 1985 (Acari, Demodecidae) from oral cavity of yellow-necked field mouse, Apodemus flavicollis (Rodentia, Muridae)

Until now, Demodex rosus has been only recorded in the Czech Republic; however, as many as 81 specimens of this species have been observed in 7 yellow-necked field mice collected from Gdansk Pomerania, Poland (prevalence 35%, mean intensity 11.6). This is the first observation of that species in Poland. In Polish fauna, Apodemus flavicollis proved to be a new host of mites belonging to Demodecidae. All specimens of D. rosus have been found in the mouse oral cavit

New data on occurrence of Demodex flagellurus (Acari, Demodecidae) – rarely recorded parasite from the house mouse Mus musculus (Rodentia, Muridae)

Demodex flagellurus Bukva, 1985 is one of two known demodecid mites of the house mouse Mus musculus Linnaeus, 1758, in which it is observed in genital area. Skin fragments of 30 house mice from various regions of Poland (residential buildings in Gdynia and Gdańsk, rural region in Wielkopolska-Kujawska Lowland) were examined. The mites were noted in 25.0% of the mice, with mean intensity of 48.0 and intensity range of 2–103. D. flagellurus demonstrated the differentiated occurrence in host populations

Demodex phylloides [Acari, Demodecidae] as a specific parasite of Sus scrofa [Mammalia, Artiodactyla]

Within 1994-2000, sections of skin collected from eleven areas on the body of 650 wild boars and 85 pigs living in the northern Poland and in the Great Poland were examined. The D. phylloides infestation in the wild boar was observed to be very heavy (prevalence 32%, mean intensity 74 ind:). In contrast, the domestic pig turned out to be free of the parasite. The wild boar D. phylloides infestations are symptomless. The parasite is relatively rare in the domestic pig, although the high animal density typical of farm stocks should aid in its spreading. Compared to that in the wild boar, the pigs affected show associated skin symptoms. Where demodicosis did occur, most often the entire population was suffering of the condition. Most probably, the wild boar is the original host of D. phylloides. The hair follicle mile in question is very frequent in the wild boar, but produces symptomless infestations. The parasite occurs more seldom in the domestic pig, but - in contrast - the infestations are much more violent

Anoplura of rodents (Rodentia) in Northern Poland

Above 100 rodents belonging to 6 species (Clethrionomys glareolus, Microtus agrestis, M. arvalis, Apodemus flavicollis, A. sylvaticus, Mus musculus) caught in the various habitations were examined. The parasites found represented three species of Anoplura: Hoplopleura acanthopus, H. affinis and Polyplax serrata. H. acanthopus appeard to be the most common parasite; it was found in all examined hosts, while mostly on the bank vole
