| diversity of babesia infecting deer ticks (ixodes dammini). | to determine whether the presence of nonpathogenic piroplasms may confound field estimates of risk of babesia microti infection, we identified sporozoites infecting the salivary glands of deer ticks (ixodes dammini) by parallel microscopy and polymerase chain reaction assays. piroplasms were evident in 14.4% of adult ticks from sites in the northcentral and northeastern united states. of these, 83.3% contained dna characteristic of ba. odocoilei. this cervid piroplasm was detected in all of the ... | 1998 | 9660456 |
| enzootic babesia microti in maine. | human babesiosis in the northeastern united states caused by babesia microti (apicomplexa: piroplasmida) is mainly reported from coastal new england sites, where deer ticks (ixodes dammini) are common. however, the piroplasm has been detected in microtine rodents elsewhere in association with i. angustus or other nidicolous ticks, suggesting that the agent is widely distributed but zoonotically significant only where a human-biting "bridge" vector is present. to determine whether this piroplasm ... | 2003 | 14627162 |
| infection and co-infection rates of anaplasma phagocytophilum variants, babesia spp., borrelia burgdorferi, and the rickettsial endosymbiont in ixodes scapularis (acari: ixodidae) from sites in indiana, maine, pennsylvania, and wisconsin. | in total, 394 questing adult blacklegged ticks, ixodes scapularis say (acari: ixodidae), collected at four sites were analyzed by polymerase chain reaction (pcr) for five microbial species: anaplasma phagocytophilum, babesia microti, babesia odocoilei, borrelia burgdorferi, and the rickettsial i. scapularis endosymbiont. identities of genetic variants of a. phagocytophilum were determined by sequencing a portion of the 16s dna. in 55% of infected ticks (193/351), a single agent was detected. in ... | 2008 | 18402145 |
| human babesiosis, maine, usa, 1995-2011. | we observed an increase in the ratio of pathogenic babesia microti to b. odocoilei in adult ixodes scapularis ticks in maine. risk for babesiosis was associated with adult tick abundance, borrelia burgdorferi infection prevalence, and lyme disease incidence. our findings may help track risk and increase the focus on blood supply screening. | 2014 | 25272145 |
