Anaplasma sparouinense
Scientific classification
Domain: Bacteria
Phylum: Pseudomonadota
Class: Alphaproteobacteria
Order: Rickettsiales
Family: Ehrlichiaceae
Genus: Anaplasma
Species: Candidatus Anaplasma sparouinense Duron et al. 2022

Candidadus Anaplasma sparouinense is an emerging intracellular bacterial pathogen.

Anaplasma sparouinense was first detected in a 58 year old man living in the rainforest of French Guiana. The patient had a history of splenectomy due to malaria attacks caused by Plasmodium vivax and showed anemia upon initial exam. Examination of the patient's Giemsa-stained blood film taken for malaria diagnosis revealed the presence of intraerythrocytic bodies. Sequencing analysis found the organism was most closely related to Candidatus Anaplasma amazonensis, a bacteria which infects sloths and cats.

Disease

Unlike the the type species of it's genus, Anaplasma phagocytophilum, which primarily infects neutrophils, A. sparouinense appears to infect red blood cells.
