High prevalence of Anaplasma phagocytophilum infection in ticks removed from human skin in north-eastern Poland.
In order to examine the risk of Anaplasma phagocytophilum infection in humans, 76 Ixodes ricinus ticks and 3 Dermacentor reticulatus removed from humans were examined for the presence of Anaplasma phagocytophilum by PCR targeting the16S rRNA gene. The average infection rate was 23.7% (18/76) in Ixodes ricinus ticks. A very high infection rate reaching 36.8% (14/38) was detected in female Ixodes ricinus, followed by males--16.6% and nymphs--10.5%. No infection was noted in larvae. All Dermacentor reticulatus also tested negative. The positive PCR products were sequenced and deposited in the Gen Bank (Accession No. DQ006828).
