Babesiosis prevalence in malaria-endemic regions of Colombia.

Babesiosis prevalence in malaria-endemic regions of Colombia. J Vector Borne Dis. 2018 Jul-Sep;55(3):222-229 Authors: Gonzalez J, Echaide I, Pabón A, Gabriel Piñeros JJ, Blair S, Tobón-Castaño A Abstract Background & objectives: : The presence of Babesia spp in humans, bovine cattle and ticks (the transmitting vector) has not been well characterized in Colombia. Babesia infection in humans can be overlooked due to similarity of the disease symptoms with malaria specially in the regions where malaria is endemic. The aim of the present work was to study the frequency of Babesia infection in humans, bovines and ticks in a malaria endemic region of Colombia, and explore the possible relationship of infection with host and the environmental factors. Methods: : A cross-sectional study was carried out between August 2014 and March 2015 to determine the frequency of B. bovis and B. bigemina infection in a sample of 300 humans involved in cattle raising, in 202 bovines; and in 515 ticks obtained from these subjects, using molecular (PCR), microscopic and serological methods. In addition, the demographic, ecological and zootechnical factors associated with the presence of Babesia, were explored. Results: : In the bovine population, the prevalence of infection was 14.4% (29/202); the highest risk of infection was found in cattle under nine months of age (OR = 23.9, CI 8.10-94.30, p = 0.0). In humans, a prevalence of 2% (...
