| babesia divergens-like infection, washington state. | most reported u.s. zoonotic cases of babesiosis have occurred in the northeast and been caused by babesia microti. in washington state, three cases of babesiosis have been reported previously, which were caused by wa1 (for "washington 1")-type parasites. we investigated a case of babesiosis in washington in an 82-year-old man whose spleen had been removed and whose parasitemia level was 41.4%. the complete 18s ribosomal rna gene of the parasite was amplified from specimens of his whole blood by ... | 2004 | 15200851 |
| comparative infectivity of babesia divergens and a zoonotic babesia divergens-like parasite in cattle. | babesia divergens-like parasites identified in human babesiosis cases in missouri and kentucky and in eastern cottontail rabbits (sylvilagus floridanus) on nantucket island, massachusetts, share identical small subunit ribosomal rna gene sequences. this sequence is 99.8% identical to that of babesia divergens, suggesting that the u.s. parasite may be b. divergens, a causative agent of human and bovine babesiosis in europe. holstein-friesian calves were inoculated with cultured nantucket island b ... | 2005 | 16282295 |
| babesia divergens-like organisms from free-ranging chamois (rupicapra r. rupicapra) and roe deer (capreolus c. capreolus) are distinct from b. divergens of cattle origin - an epidemiological and molecular genetic investigation. | in 2005 and 2006, three adult female chamois (rupicapra r. rupicapra) were found dead with signs of acute babesial infection in the eastern swiss alps. pcr on dna extracted from blood or spleen of the carcasses revealed sequence identity of the amplified part of the 18s rrna gene with genbank entries attributed to babesia divergens of cattle origin or b. capreoli of wild ruminant origin which have never been described before in this region. examination of 424 blood samples from 314 head of cattl ... | 2008 | 18400402 |
| babesia species occurring in austrian ixodes ricinus ticks. | babesiosis is a tick-transmitted disease of veterinary and medical importance. the first austrian case of human babesiosis was recently recorded. in the current study, ticks at all life cycle stages (instars), including 853 ixodes ricinus and 11 haemaphysalis concinna ticks, from sampling sites throughout austria were examined for the presence of babesia spp. by using 18s rrna gene pcr and sequencing, and the overall mean infection rate was 51.04%. the infection rates for sampling sites were hig ... | 2008 | 18539787 |
| one health approach to identify research needs in bovine and human babesioses: workshop report. | abstract: background: babesia are emerging health threats to humans and animals in the united states. a collaborative effort of multiple disciplines to attain optimal health for people, animals and our environment, otherwise known as the one health concept, was taken during a research workshop held in april 2009 to identify gaps in scientific knowledge regarding babesioses. the impetus for this analysis was the increased risk for outbreaks of bovine babesiosis, also known as texas cattle fever, ... | 2010 | 20377902 |
