The objective of the study was to determine the prevalence rate of 3 Borrelia burgdorferi genospecies in Ixodes ricinus ticks collected from wooded areas of the Lublin region (eastern Poland). A group of 1,813 I. ricinus ticks from 6 districts were examined for the presence of Borrelia burgdorferi sensu lato (B.b.s.l.) by polymerase chain reaction (PCR).(More)
The objective of the present study was to assess the risk of borreliosis and anaplasmosis (ehrlichiosis) among the forestry workers of the Roztocze National Park (south-eastern Poland) by examination of Ixodes ricinus ticks living in park area with PCR method, and by the serological and clinical examination of the workers. In 406 examined ticks, the(More)
A total of 875 nymphal and adult Ixodes ricinus ticks and 148 adult Dermacentor reticulatus ticks were collected by flagging lower vegetation in the Lublin region (eastern Poland) and examined for the presence of RNA of tick-borne encephalitis virus (TBEV) by nested RT-PCR. The minimum infection rate of I. ricinus ticks with TBEV amounted to 1.6% while the(More)
The objective of present work was to determine and compare the components of bioaerosol in several sectors of plant processing industries. The study was conducted in 10 facilities engaged in herb and grain processing, flax threshing, grain storing, baking, and cereals production. The air samples were taken on glass fibre filters with an AS-50 sampler. We(More)
Among various species of parasitic protozoans which may contaminate drinking water, Toxoplasma gondii is of a special importance due to the high incidence of infections with this parasite noted in animals and humans. The objective of this study was to determine the frequency of occurrence of T. gondii in drinking water on farms in the area of the Lublin(More)
136 eastern-Polish farming students (51 females and 85 males, aged 16-23 years) underwent clinical examination, skin prick tests with common and farm-specific allergens, total IgE measurement and Phadiatop test. Atopy was found in 35.3% (95% CI: 27.3-43.3%) of students. For allergic skin diseases, the point prevalence was 5.9%, the lifetime prevalence(More)
Microbiological air sampling was performed in a medium-size sewage treatment plant processing municipal wastewater from a city located in eastern Poland. Air samples for determination of the concentrations of viable mesophilic bacteria, Gram-negative bacteria, thermophilic actinomycetes, fungi and endotoxin were collected at 12 sites associated with various(More)
Studies of indoor bioaerosols conducted in Central and Eastern European countries, as a result of the scarcity of funding, mostly do not attain the level presented by similar studies in Northern America and Western Europe. For socio-economic reasons, most of the intense studies on indoor bioaerosols in Central and Eastern European countries were carried out(More)
The microbiological composition of tobacco products was studied using culture and chemical analysis (of tobacco leaves) or chemical analysis only (tobacco and tobacco smoke). The chemical analyses utilized gas chromatography-tandem mass spectrometry for determining 3-hydroxy fatty acids, muramic acid, and ergosterol as markers of respectively(More)
The aim of this study was to determine the size distribution of bacteria and fungi occurring in the air of human dwellings. The concentration and size distribution of particulate aerosol, Gram-positive mesophilic bacteria, Gram-negative mesophilic bacteria and fungi were examined in 60 flats situated in the Upper Silesia conurbation, southern Poland.
