Intracellular bacterial pathogen
| Anaplasma sparouinense | |
|---|---|
| Scientific classification | |
| Domain: | Bacteria |
| Phylum: | Pseudomonadota |
| Class: | Alphaproteobacteria |
| Order: | Rickettsiales |
| Family: | Ehrlichiaceae |
| Genus: | Anaplasma |
| Species: | Candidatus Anaplasma sparouinense Duron et al. 2022 |
Candidatus Anaplasma sparouinense is an emerging intracellular bacterial pathogen.
Description
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 its genus, Anaplasma phagocytophilum, which primarily infects neutrophils, A. sparouinense appears to infect red blood cells.
