Prevalence of Borrelia burgdorferi sensu lato in Ixodes ricinus ticks collected from southern Poland.

In 2008-2011 ticks were collected from southern Poland. Out of 6336 individuals collected and identified as Ixodes ricinus, 768 (2 larvae, 84 nymphs, 417 females, 265 males) were included in molecular study. The aim of this study was to investigate the prevalence and types of genospecies of Borrelia burgdorferi sensu lato in ticks.

The risk of exposure to Anaplasma phagocytophilum, Borrelia burgdorferi sensu lato, Babesia sp. and co-infections in Ixodes ricinus ticks on the territory of Niepołomice forest (southern Poland).

Niepołomice Forest is located about 20 kilometers east of Cracow (Malopolska province, southern Poland). Its natural and touristic values, as well as wide range of hosts occurring within indicate this to be an area of high risk of exposure to Ixodes ricinus and tick-borne diseases it transfers. I.

[Prevalence of Borrelia burgdorferi sensu lato in ticks, Ixodes ricinus in Tarnowskie Góry district].

Borrelia burgdorferi is an aetiological factor of borreliosis (Lyme disease). The main vectors of Borrelia burgdorferi are larvae, nymphs, and females of Ixodes ricinus. The aim of this paper was to analyse infection parameters of Borrelia burgdorferi in a selected populations of Ixodes ricinus.

Cellular toxicity of oxycholesterols.

Oxycholesterols (OS) are formed from cholesterol or its immediate precursors by enzymatic or free radical action in vivo, or they may be derived from food. OS exhibit a wide spectrum of biological activities. In OS cytotoxicity, several mechanisms seem to be involved: e.

The usefulness of calyculin a for cytogenetic prenatal diagnosis.

An increased number of chromosome plates can be obtained by use of calyculin A (CLA). CLA is an inhibitor of protein phosphatases (type 1 and type 2A serine/threonine). Inactivation of these phosphatases leads to premature chromosome condensation (PCC) in all phases of the cell cycle; thus, it is possible to investigate both metaphase and G(2)-PCC chromosomes.
