| molecular detection of rickettsia aeschlimannii in hyalomma spp. ticks from camels (camelus dromedarius) in nigeria, west africa. | several species of the spotted fever group rickettsiae have been identified as emerging pathogens throughout the world, including in africa. in this study, 197 hyalomma ticks (ixodida: ixodidae) collected from 51 camels (camelus dromedarius) in kano, northern nigeria, were screened by amplification and sequencing of the citrate synthase (glta), outer membrane protein a (ompa) and 17-kda antigen gene fragments. rickettsia sp. glta fragments were detected in 43.3% (42/97) of the tick pools tested. ... | 2015 | 25565180 |
