Summary: | Bacteria belonging to the family Anaplasmataceae cause infections in humans and domestic animals. The consequences of infection can be significant economic losses for farmers. To better understand the epidemiology of tick-borne Anaplasmataceae in Corsica, we used molecular methods to detect and characterize Anaplasmataceae in ixodid ticks collected from cattle. Anaplasmataceae were detected by using a real-time polymerase chain reaction (PCR) targeting the 23S rRNA gene. Partial sequencing of
rpoB
and g
roEL
allowed identifying species and conducting phylogenetic analyses. Infection rates were calculated using maximum likelihood estimation (MLE) with 95% confidence intervals (CIs). In total, 597
Rhipicephalus bursa
, 216
Hyalomma marginatum
, and seven
Ixodes ricinus
were collected from cattle during July–August 2017 and July–December 2018. Overall, Anaplasmataceae DNA was detected in 15 of 255 tick pools (MLE = 1.7%; 95% CI 0.9–2.7%). The molecular analysis revealed two species within the genus
Anaplasma
:
A. marginale
and
A. phagocytophilum
. We also detected bacteria within the genus
Ehrlichia
: we confirmed the detection of
E. minasensis
DNA in
H. marginatum
and
R. bursa
tick pools collected from cattle in Corsica and detected, for the first time to our knowledge,
Candidatus
E. urmitei in Corsican
R. bursa
ticks and a potential new species,
Candidatus
E. corsicanum. Further studies are needed to ascertain the pathogenesis and zoonotic potential of the strains and their importance for animals and public health. |
