| infection with a babesia-like organism in northern california. | human babesiosis is a tick-transmitted zoonosis associated with two protozoa of the family piroplasmorida: babesia microti (in the united states) and b. divergens (in europe). recently, infection with an unusual babesia-like piroplasm (designated wa1) was described in a patient from washington state. we studied four patients in california who were identified as being infected with a similar protozoal parasite. all four patients had undergone splenectomy, three because of trauma and one because o ... | 1995 | 7816065 |
| there are at least three genetically distinct small piroplasms from dogs. | the 18s nuclear subunit ribosomal rna (18s rrna) gene of small piroplasms isolated from dogs from okinawa (japan), oklahoma, north carolina, indiana, missouri, and alabama, was isolated and sequenced. phylogenetic analysis of these sequences and comparisons with sequences from other babesia, cytauxzoon, and theileria species revealed that all canine small babesial isolates, with the exception of isolates from california and spain, were placed in a group containing the babesia spp. sensu stricto. ... | 2000 | 11428342 |
| babesiosis acquired through blood transfusion, california, usa. | babesiosis was reported in a california resident who received a transfusion of blood products collected in the disease-endemic northeastern region of the united states. babesiosis should be considered year-round in the diagnosis of febrile and afebrile patients with abnormal blood cell counts who have received blood products from disease-endemic areas. | 2009 | 19402969 |
| The third described case of transfusion-transmitted Babesia duncani. | BACKGROUND: Almost all of the reported US tick-borne and transfusion-associated Babesia cases have been caused by Babesia microti, which is endemic in the Northeast and upper Midwest. We investigated a case caused by B. duncani (formerly, the WA1-type parasite), in a 59-year-old California resident with sickle cell disease (HbSS) whose only risk factor for infection was receipt of red blood cell transfusions. CASE REPORT: The patient's case was diagnosed in September 2008: intraerythrocytic para ... | 2011 | 22168221 |
