Fatal acute babesiosis associated with Babesia venatorum infection (Babesia sp. EU1) in a captive reindeer calf in Switzerland.


Novacco, Marilisa; Hofmann-Lehmann, Regina; Grimm, Felix; Meli, Marina L; Stirn, Martina (2019). Fatal acute babesiosis associated with Babesia venatorum infection (Babesia sp. EU1) in a captive reindeer calf in Switzerland. Veterinary parasitology. Regional studies and reports, 18:100336.

Abstract

Babesia venatorum was isolated from a captive reindeer calf in Switzerland. The clinical signs consistent with acute babesiosis included hemolytic anemia and hemoglobinuria. The diagnosis was made based on visualization of intraerythrocytic parasites in the stained blood smears and confirmed by PCR analysis of the 18S rRNA gene, with subsequent species identification within Babesia confirmed by sequencing. The reindeer calf was initially treated with supportive care and an antiprotozoal drug (imidocarb dipropionate) but died a few days after hospitalization. Babesia venatorum is also known as Babesia sp. EU1 and can infect different mammalian species, including humans. The current case report aims to increase awareness among veterinarians and reindeer owners about the presence and the associated risk of this zoonotic pathogen. Considering the high morbidity and possible mortality associated with acute babesiosis, captive reindeer should receive tick prevention measures and be tested for subclinical infections in endemic area.
