Serological Detection of Flavivirus Infections in Saudi Baboons.

To evaluate the risk to public health from Flaviviruses in the southwest region of the Kingdom of Saudi Arabia, we screened as sentinels, 50 commensal hamadryas baboons located at a peri-domestic site on the outskirts of Ta'if City in February 2013. Of the baboons, 12% [95% CI 5, 24], 0% [95% CI 0, 7] and 10% [95% CI 3, 22] were seropositive in a pan-Flavivirus ELISA (anti-pan-WNV 1-2, Usutu, Zika), Dengue virus 1-4 ELISA (anti-DENV 1-4) and WNV-1 PRNT, respectively, indicating Flavirus exposures of the subjects with possible risk to public health in the area.

A study on the social structure and dispersal patterns of hamadryas baboons living in a commensal group at Taif, Saudi Arabia.

Three levels of hamadryas social structure--the one male unit (OMU), the band, and the troop--have been observed at all sites studied, but a fourth--the clan--has been observed at only one site, Erer-Gota, Ethiopia, during a longitudinal check of the dispersion of identified individuals. The clan is important since it appears to provide the basis for male philopatry, although comparative data is needed from other sites to confirm this. We studied a huge commensal group of hamadryas baboons (over 600 animals) in Saudi Arabia.

Crossing the Red Sea: phylogeography of the hamadryas baboon, Papio hamadryas hamadryas.

The hamadryas baboon (Papio hamadryas hamadryas) is found both in East Africa and western Arabia and is the only free-ranging nonhuman primate in Arabia. It has been hypothesized that hamadryas baboons colonized Arabia in the recent past and were possibly even transported there by humans. We investigated the phylogeography of hamadryas baboons by sequencing a portion of the control region of mtDNA in 107 baboons from four Saudi Arabian populations and combing these data with published data from Eritrean (African) P.
