title: [Assessment of rate of infection with agents of bacterial infections in ticks captured on one of the Moscow park terrains].
abstract: OBJECTIVE
  To study the rate of infection of ticks captured one of the Moscow park terrains with bacteria (agents of tick borreliosis and anaplasmosis).
  
  
  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". Number of ticks on the chosen terrain was 1.77 ticks per km2. 22.4% of ticks (12 females and 5 males) were positive for the agent of tick borreliosis--spirochete Borrelia burgdorferi sensu lato which is pathogenic for humans. The main detected pathogen was Euro-Asian genovariant of B. garinii--7 female and 5 male ticks (70.6% from total number of infected ticks) were infected with it. Five female ticks were infected with genovariant of B. afzelii. One female tick (1.2%) was infected with B. valaisiana.
  
  
  CONCLUSIONS
  Anaplasma A. phagocytophilum causing human granulocytic anaplasmosis was not detected in captured adult ticks.
