Detection of Babesia Sp. EU1 and Members of Spotted Fever Group Rickettsiae in Ticks Collected from Migratory Birds at Curonian Spit, North-Western Russia

A groundbreaking study on the Curonian Spit reveals that migratory birds may serve as reservoirs for human pathogens. Researchers detected Babesia sp. EU1 and spotted fever group (SFG) rickettsiae in ticks collected from passerine birds, marking the first such findings in this region. Using PCR analysis, 1.6% of ticks tested positive for Babesia spp., with sequences matching human pathogenic strains, while 15.1% carried SFG rickettsiae, including Rickettsia helvetica, monacensis, and japonica. This suggests a potential role for migratory birds in the epidemiology of these diseases, warranting further investigation into their transmission dynamics.
