[Assessment of rate of infection with agents of bacterial infections in ticks captured on one of the Moscow park terrains].

Aim: To study the rate of infection of ticks captured one of the Moscow park terrains with bacteria (agents of tick borreliosis and anaplasmosis).

Materials And Methods: Rates of infection of dried ticks with agents of main tick-borne bacterial infections (tick borreliosis and anaplasmosis) were determined by nested PCR.

Results: In May-June 2006, 76 ticks (40 adult females, 36 adult, males) belonged to Ixodes ricinus species were captured by the method "on flag".

Prevalence of Anaplasma phagocytophilum and its coinfection with Borrelia afzelii in Ixodes ricinus and Ixodes persulcatus ticks inhabiting Tver Province (Russia) - a sympatric region for both tick species.

Human granulocytic anaplasmosis (HGA) and Lyme borreliosis (LB) are tick-borne infectious diseases caused by Anaplasma phagocytophilum and Borrelia burgdorferi sensu lato species, respectively. In this study, p44/msp2 paralogues specific to A. phagocytophilum and 5S-23S rRNA gene-intergenic spacers specific to B.

Effect of proteins from the spirochete Borrelia burgdorferi sensu lato on myelinated nerve excitability.

We studied the effect of spirochete Borrelia burgdorferi sensu lato cell membrane proteins on excitability of myelinated nerve fiber. It was found that cell surface proteins of spirochetes B. burgdorferi s.

Widespread distribution and high prevalence of an alpha-proteobacterial symbiont in the tick Ixodes ricinus.

The tick Ixodes ricinus is responsible for the transmission of a number of bacterial, protozoan and viral diseases to humans and animals in Europe and Northern Africa. Female I. ricinus from England, Switzerland and Italy have been found to harbour an intracellular alpha-proteobacterium, designated IricES1, within the cells of the ovary.

Characterization of Borrelia burgdorferi sensu lato isolated in Moscow province--a sympatric region for Ixodes ricinus and Ixodes persulcatus.

The relationships between Borrelia species and the vector ticks, Ixodes persulcatus and Ixodes ricinus were examined in a molecular epidemiological study. We conducted a survey in the Moscow region which is a sympatric region for both species of tick. We examined 630 unfed I.
