Puolassa on löydetty noin 2 %:sta punkkeja myös babesioosia (muistuttaa pääosin Irlannista + muualta Euroopasta löydettyä kantaa). Puolassa on muutenkin ollut erittäin voimakas punkkivuosi + paljon uusia infektioita.

Ps. borreliabakteerille ei tule immuuniksi, joten kannattaa olla erittäin varovainen ettei saa uutta infektiota!


According to the doctors in Miedzyrzecz,Western Poland, this year is already a record for ticks and their infections in that region. They say that it will be the worst year on record EVER for tick treatments and this is just
the start (April) so they are gearing up for some serious stuff over the next 6 months. Some reckon the ticks are getting hardier (surviving frost) whilst others say that breeding has started early...and Poland has just experienced one of the coldest winters on record.

In the present study, PCR has been applied to detect and analyze DNA of Babesia spp. extracted from Ixodes ricinus ticks. Collection of I. ricinus was made in 6 forested areas of Zachodniopomorskie Voivodship, Poland, during 2 seasonal peaks of tick activity, i.e., spring and autumn, 2001. In total, 1,328 I. ricinus were collected and processed for PCR with F34 and R323 primers. Babesia spp. was detected in 28 (2% of 1,328 tested) ticks; 26 were identified as B. divergens. The other 2 were identified as B. microti. PCR was conducted with 18S rRNA specific primers and sequencing was processed to precisely identify and compare these isolates with B. microti and B. divergens sequences from Europe, North America, and Asia obtained from the GenBank. Analysis revealedthat sequences of B. microti from northwestern Poland are almost identical (99.94%) with those referred to as "Munich strain"; both form a clade different from other European strains, as well as those from Asia and North America (called B. microti, sensu stricto). An investigation performed with B. divergens sequences showed that the sequence from northwestern Poland is 99.94% homologous to an isolate from Ireland ("Purnel"), and differs in just a few nucleotides from other European sequences. Phylogenetic analysis revealed that the sequence of B divergens isolated from Polish ticks form a group that comprise 4 European sequences from Great Britain and Ireland and is, therefore, closely related to other European and North American B. divergnens sequences.
