Babesiosis is a tick-borne disease caused by eukaryotic Babesia parasites which are morphologically similar to Plasmodium falciparum, the causative agent of malaria in humans. Like Plasmodium, different species of Babesia are tuned to infect different mammalian hosts, including rats, dogs, horses and cattle. Most species of Plasmodium and Babesia possess an essential bifunctional enzyme for nuc...
Transforming growth factor beta-1 (TGF-beta1) is a pleiotropic cytokine with both pro- and antiinflammatory properties, depending on its environment and concentration. The present study evaluated the effects of orally-delivered TGF-beta1 on mice parenterally-infected with various protozoan parasites. We report that while orally-administered TGF-beta1 seems to confer partial protection against m...
Infection of severe combined immunodeficient mice with Babesia sp. strain WA1 was studied to assess the contributions of innate and adaptive immunity in resistance to acute babesiosis. The scid mutation showed little effect in genetically susceptible C3H mice and did not decrease the inherent resistance of C57BL/6 mice to the infection, suggesting that innate immunity plays a central role in de...
Molecular Characterization of a Non–Babesia divergens Organism Causing Zoonotic Babesiosis in Europe
In Europe, most reported human cases of babesiosis have been attributed, without strong molecular evidence, to infection with the bovine parasite Babesia divergens. We investigated the first known human cases of babesiosis in Italy and Austria, which occurred in two asplenic men. The complete 18S ribosomal RNA (18S rRNA) gene was amplified from specimens of their whole blood by polymerase chain...
Human babesiosis is an increasing health concern in the northeastern United States, where the causal agent, Babesia microti, is spread through the bite of infected Ixodes scapularis ticks. We sampled 10 mammal and 4 bird species within a vertebrate host community in southeastern New York to quantify reservoir competence (mean percentage of ticks infected by an individual host) using real-time P...
With babesiosis in dogs, the capillary network is especially strongly affected due to stimulation of hemostasis system and development thrombus formation microvasculature. Acute renal failure even death animals are caused by shock phenomena syndrome disseminated intravascular coagulation. Clinical, laboratory (hematological, biochemical, coagulometric, hemodynamic, enzyme immunoassay) methods r...
