Although Lyme disease has been endemic to parts of the Lower Hudson Valley of New York, United States, for >2 decades, babesiosis has emerged there only since 2001. The number of Lower Hudson Valley residents in whom babesiosis was diagnosed increased 20-fold, from 6 to 119 cases per year during 2001-2008, compared with an ≈1.6-fold increase for the rest of New York. During 2002-2009, a total o...

Canine babesiosis is an important worldwide, tick-borne disease caused by hemoprotozoan parasites of the genus Babesia. Babesia gibsoni is the predominant species that causes canine babesiosis in Taipei, Taiwan. It is a small pleomorphic intraerythrocytic parasite that can cause erythrocyte destruction and hemolytic anemia. Efficacy of oral administration of a doxycycline-enrofloxacin-metronida...

The medical records of 17 patients with babesiosis were reviewed. Nine of 17 patients (52.9%) presented with fever (temperature, > 101 degrees F), and 8 of the 9 patients (88.9%) had relative bradycardia. Four of the nine patients (44.4%) had morning temperature spikes during initial hospitalization. As revealed by laboratory analysis, 13 of 17 patients (76.5%) with babesiosis had lymphopenia, ...

H uman babesiosis in the United States is attributable almost exclusively to infection with the intraerythro-cytic protozoan parasite Babesia microti. The primary mechanism of parasite transmission to humans is by the bite of an infected deer/black-legged tick, Ixodes scapularis, the same tick that serves as the vector for Lyme borreliosis, human granulocytic anaplasmosis, and several other tic...

Babesiosis is a malaria-like illness caused by the intraerythrocytic parasite Babesia microti and is transmitted by the same tick that transmits Borrelia burgdorferi, the causative agent of Lyme disease. Babesiosis is well recognized in adult residents of southern New England and New York but has been described in only five children. To determine whether children are infected with B microti les...

Babesiosis is an emerging zoonosis now found in several areas of the world. Using PCR and indirect immunofluorescence assay, we have diagnosed the first case of human babesiosis caused by Babesia microti in Spain. Diagnosis was delayed because of the nonspecific clinical symptoms that occurred in an immunocompetent patient.

Babesiosis is a tick-borne protozoan disease which principally affects animals but occasionally affects humans. Cases have been reported from many parts of Europe with no evidence of case-clustering. We report the second case of babesiosis from a small area in the west of Ireland.

Babesiosis in humans is caused by infection with various species of Babesia (Apicomplexa, Piroplasmida), mainly transmitted by an arthropod vector--Ixodes spp. ticks. This review will focus on blood transfusion as another mode of Babesia transmission, especially in endemic areas, as well as the impact of human babesiosis on transfusion medicine.
