| Sumario: | <i>Babesia</i> ssp. and <i>Anaplasma</i> spp. are tick-borne microorganisms representing a possible health risk for domestic and wild animals, as well as humans. Roe deer serve as a suitable reservoir host for some species ascribed to <i>Babesia</i> spp. and <i>Anaplasma phagocytophilum</i> taxa, also due to its important role in the maintenance of large populations of <i>Ixodes ricinus</i>, the main tick vector of these pathogens in Europe. Roe deer populations have been recently expanding throughout Europe, namely in Italy. However, the collection of samples from free-ranging wild animals for diagnostic investigations often includes several practical issues. This problem can be overcome using samples provided by wildlife rescue centers making them available for investigations following routine analyses. The presence of <i>Babesia</i> spp. and <i>Anaplasma</i> spp. in blood samples of 43 roe deer rescued by a wildlife rescue center in Emilia-Romagna region (Italy) was molecularly investigated. PCR screening revealed the presence of at least one pathogen in 86.05% of the animals, while co-infection occurred in 18.92% of the tested individuals. Zoonotic <i>Babesia venatorum</i> was found in 6.98% of the samples, while <i>Babesia capreoli</i> and <i>Anaplasma phagocytophilum</i> were detected in 74.42% and in 20.93%, respectively. No hematological signs compatible with clinical anaplasmosis or piroplasmosis, as well as absence of intracellular circulating microorganisms in blood smears, were observed, suggesting asymptomatic infection in the tested animals. These results confirm the usefulness of wild rescued animals as convenient source of biological samples for tick-borne pathogens investigation and the role of roe deer as a key factor in the endemic cycle of <i>Babesia</i> species and <i>A. phagocytophilum</i>. |
