Severe Anaplasma phagocytophilum and Babesia divergens concomitant infection in imported captive reindeer (Rangifer tarandus)
Lola Romanos | Renaud Pierre Maillard
Tick-borne diseases are highly prevalent in domestic and wild ruminants and they may be distributed in wide geographical ranges by animal transportation. The aim of the current study was to investigate the presence of European strains of Babesia spp. and/or Anaplasma spp. in oversea imported reindeer specimens. Imported specimens (n=7) were hospitalized with visible tick infestation (Ixodes ricinus) and signs of cachexia, anemia, and hemoglobinuria. Using blood smears, PCR, and BLAST comparisons, it was confirmed that the animals were infected with a French strain of Anaplasma phagocytophilum and Babesia divergens which is considered to be absent in the USA. We conclude that oversea importation of reindeers must be followed with a routine check for geographically-specific strains of pathogens from the place of origin. This monitoring process must be dynamic and according to recent reports of tick-borne pathogens.
