First Cases of Transplacental Transmission of Anaplasma spp. in Gabon: Cases Reports and Brief Review of the Literature

Anaplasma spp. is an emerging human zoonosis, usually transmitted by tick bites. Human-to-human transmission is rare, and transplacental transmission is even less common. No cases of transplacental transmission have been previously reported.We report the cases of patients who were followed up for febrile syndrome diagnosed with maternal-fetal infection and treated with antibiotic therapy and hemodynamic correction. Investigation of the etiology revealed Anaplasma spp. in a neonatal infection.These cases prove that transplacental transmission of Anaplasma spp. is possible and that surveillance is important.
