Venäjän punkeista löydettiin borreliabakteerien lisäksi riketsiaa (nimeltään Montezuma) ja ehrlichiaa.

Muut riketsioosit.
Vuoden 1985 jälkeen on tähän mennessä todettu jo kahdeksan uuden riketsian aiheuttavan infektioita ihmiselle. Rickettsia helveticaksi nimetty, alun perin Ranskasta löydetty riketsia on nykytiedon mukaan ainoa Skandinavian alueella esiintyvä riketsia. Ruotsissa on todettu 22 % punkeista kantavan tätä bakteeria. Vuonna 1999 julkaistiin ensimmäiset potilastapaukset, joissa osoitettiin Rickettsia helvetican aiheuttavan infektion ihmiselle. Julkaisussa esiteltiin kaksi potilastapausta, joissa R. helvetica oli aiheuttanut kroonisen sydänlihaksen ja sydänpussin tulehduksen (perimyokardiitin) seurauksena äkillisen potilaan kuoleman.....

The prevalence of rickettsiae, ehrlichiae, and the rickettsia-like endosymbiont called Montezuma relative to that of Borrelia was determined in questing Ixodes persulcatus (I. persulcatus) ticks collected in 2002-2003 from Vologda Province, Russia. Ehrlichia muris, Anaplasma phagocytophilum, Montezuma, and new spotted fever group rickettsiae were detected by polymerase chain reaction (PCR) for the first time in this area. The rickettsiae were all Candidatus Rickettsia tarasevichiae, the furthest west this organism has been detected. After Borrelia, Montezuma was the agent most frequently detected; it may be present throughout the distribution of I. persulcatus in Russia. Ehrlichiae and rickettsiae frequently share the same tick host with Borrelia burgdorferi sensu lato so cotransmission and mixed infections in vertebrate hosts, including humans, may occur.

A total of 4701 Ixodes ricinus, collected during the summer of 2003, were analyzed for three pathogens. DNA was detected from the three pathogens. Co-detection of more than one pathogen was observed.

Our aim was to determine the presence of Rickettsia spp. and Bartonella spp. in Ctenocephalides felis and Ctenocephalides canis from La Rioja (Spain). A total of 88 specimens were tested by polymerase chain reaction (PCR) using gltA and ompB genes as targets for Rickettsia spp., and 16S rRNA and ribC genes for Bartonella spp. Rickettsia felis-like (28.4%), Bartonella clarridgeiae (6.8%), and Bartonella henselae (3.4%) were detected in Ctenocephalides spp. Other Bartonella sp. different from B. clarridgeiae and B. henselae could also be present in fleas from La Rioja.

Ixodes ricinus, the most commonly observed tick species in Poland, is known vector of microorganisms pathogenic for humans as TBE virus, Borrelia burgdorferi s.1., Anaplasma phagocytophilum and Babesia sp. in this country. Our study aimed to find out whether this tick can also transmit also rickettsiae of the spotted fever group (SFG). DNA extracts from 560 ticks (28 females, 34 males, and 488 nymphs) collected in different wooded areas in northern Poland were examined by PCR for the detection of Rickettsia sp., using a primer set RpCS.877p and RpCS.1258n designated to amplify a 381-bp fragment of gltA gene. A total of 2.9% ticks was found to be positive. The percentage of infected females and males was comparable (10.5% and 11.8%, respectively) and 6.6-7.6 times higher than in nymphs (1.6%). Sequences of four PCR-derived DNA fragments (acc. no. DQ672603) demonstrated 99% similarity with the sequence of Rickettsia helvetica deposited in GenBank. The results obtained suggest the possible role of I. ricinus as a source of a microorganism, which recently has been identified as an agent of human rickettsioses in Europe.
