Ethnomedicinal use of vultures by traditional medicinal practitioners in Ghana

Vultures form an important ingredient used by traditional medicinal practitioners for the preparation of their therapeutic remedies. The aim of this study was to determine the vulture body parts used for alleviating human ailments by traditional medicinal practitioners in Ghana. Data on the vulture body parts used and human ailments used to alleviate were collected from 28 traditional medicinal practitioners using semi-structured questionnaires. The vulture head, brain, claw, beak, bones and feathers were identified as the body parts used for traditional medicinal purposes. Use values and informant agreement ratio were calculated; the vulture head was found to be the most culturally important body part for treating human ailments, while the feathers had the highest informant agreement ratio. Human ailments that vulture body parts were used to treat include rheumatism, headache,bedwetting and diabetes, while protection against witchcraft was the main spiritual ailment that vulture body parts were used for. This study revealed the high cultural importance of vultures to traditional medicinal practitioners in Ghana. Vulture body parts were particularly important for spiritual ailments that have no orthodox  treatment.Keywords: conservation, cultural importance, Ghana, traditional medicinal practitioners, vultur

Lagos Bat Virus Infection Dynamics in Free-Ranging Straw-Colored Fruit Bats (Eidolon helvum)

Bats are key species for ecological function, but they are also reservoirs of zoonotic agents, such as lyssaviruses that cause rabies. Little is known about the maintenance and transmission of lyssaviruses in bats, although the observation of clinically sick bats, both in experimental studies and wild bats, has at least demonstrated that lyssaviruses are capable of causing clinical disease in bat species. Despite this, extensive surveillance for diseased bats has not yielded lyssaviruses, whilst serological surveys demonstrate that bats must be exposed to lyssavirus without developing clinical disease. We hypothesize that there is endemic circulation of Lagos bat virus (LBV) in the straw-coloured fruit bat (Eidolon helvum) in Ghana, West Africa. To investigate this further, longitudinal blood sampling was undertaken quarterly between 2012 and 2014 on wild E. helvum at two sites in Ghana. Serum samples were collected and tested for LBV-neutralizing antibodies using a modified flourescent antibody virus neutralisation (FAVN) assay (n = 294) and brains from moribund or dead bats were tested for antigen and viral RNA (n = 55). Overall, 44.7% of the 304 bats sampled had LBV-neutralising antibodies. None of the brain samples from bats contained lyssavirus antigen or RNA. Together with the results of an earlier serological study, our findings demonstrate that LBV is endemic and circulates within E. helvum in Ghana even though the detection of viral infection in dead bats was unsuccessful. Confirmation that LBV infection is endemic in E. helvum in Ghana is an important finding and indicates that the potential public health threats from LBV warrant further investigation
