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%. ...
متن کاملFirst report of Babesia divergens infection in an HIV patient.
Human babesiosis is a zoonosis primarily transmitted through Ixodes ticks and alternatively by routes such as blood transfusions from asymptomatic donors. We report the first case of human babesiosis caused by Babesia divergens in a patient with HIV. This study also focuses on elucidating the possible transmission route of infection in this patient, who received numerous blood transfusions but ...
متن کاملNovel diamidines with activity against Babesia divergens in vitro and Babesia microti in vivo.
Dicationic diamidines, such as diminazene and pentamidine, are well-studied chemotherapeutic agents with significant activity against parasitic diseases. The in vitro activities of novel diamidine compounds against the Babesia divergens strains 1903B and 4201 were investigated. The most potent compound, a diphenyl furan, had a 50% inhibitory concentration (IC(50)) of 1.5 ng/ml. In a murine mode...
متن کاملSika Deer Carrying Babesia Parasites Closely Related to B. divergens, Japan
To the Editor: Human babesiosis caused by Babesia divergens, a zoonotic pathogen of bovines in Europe, is an emerging tickborne disease (1). In the United States, a closely related Babesia sp. was identified in persons in Missouri and Kentucky and in eastern cottontail rabbits (Sylvilagus floridanus) on Nantucket Island, Massachusetts (2–5). We report that sika deer (Cervus nippon) in Japan als...
متن کاملBabesia divergens apical membrane antigen 1 and its interaction with the human red blood cell.
Multiple parasite ligand-erythrocyte receptor interactions must occur for successful Babesia and Plasmodium invasion of the human red cell. One such parasite ligand is the apical membrane antigen 1 (AMA1) which is a conserved apicomplexan protein present in the micronemes and then secreted onto the surface of the merozoite. Much evidence exists for a vital role for AMA1 in host cell invasion; h...
