The Status

Primate species are not widely explored in Ghana’s savannah ecosystems.  We report data on encounter rates and group sizes of primates at the Mole National Park in Ghana.  Forty transects, each of 5km length, were randomly laid in the park for the study.  Four species of primates were visually recorded during field surveys: Olive Baboon Papio anubis, Patas Monkey Erythrocebus patas, Green Monkey Chlorocebus sabaeus and Colobus vellerosus.  The status of C. vellerosus is Critically Endangered, the status of the other species is Least Concern according to the IUCN Red List.  Encounter rates (groups/km) were 0.98, 0.65 and 0.45 for Olive Baboons, Patas Monkeys and Green Monkeys respectively.  The mean group sizes were: Olive Baboon 10.8 (SE=1.1, range=1-38), Patas Monkey 12.2 (SE=3.3, range=1-35), and Green Monkey 10.0 (SE=1.9, range=1-25).  Only one group of White-thighed Colobus with a group size of six was encountered.  Encounter rates and group sizes of the same species varied in different parts of the park, and factors such as resource distribution and security against secret hunting may have influenced this variation.  Authors recommend further studies to facilitate better understanding of these primates.

ABSTRACTAnti-Trypanosoma brucei brucei and anti-Trypanosoma congolense activities of sera from two species of uninfected zoo-primates, Erythrocebus patas (red patas monkey) and Chlorocebus tantalus (tantalus monkey) were investigated. The sera were screened using thick films and haematocrit centrifugation technique (HCT), to ensure that the donor primates were not infected with trypanosomes. Trypanosoma brucei brucei (Federe strain) and Trypanosoma congolense were suspended in supplemented RPMI (Rossvelt Park Memorial Institute) 1640 medium and the motility of the parasite was used as index of viability after the addition of each test serum. The selected primate sera exhibited some degree of anti-Trypanosoma brucei brucei activities in vitro. Red patas monkey serum had an inhibition index of 0.27, while that of Tantalus monkey was 0.34, against Trypanosoma brucei brucei, with mean survival times of 22.00±1.73 hours for red patas monkey serum and 19.67±0.58 hours for tantalus monkey serum, which are significantly lower (P<0.05) than that of the control (30.00±0.00 hours). The selected primate sera had pronounced inhibitory activities against Trypanosoma congolense. Sera from the two species of primate had very high anti-Trypanosoma congolense activity showing an inhibition index of 0.91 for Red patas monkey serum and 0.90 for Tantalus monkey serum, with marked and significant reduction (P<0.05) in survival time of 7.00±1.73 hours in Red patas monkey serum and 7.67±0.58 hours in Tantalus monkey serum, compared with the control (74.00±1.00 hours). The in vitro anti-trypanosomal activity of the serum samples was shown to be cidal in nature. The activity was not associated with xanthine oxidase. This study revealed that sera from red patas monkey and tantalus monkey had a moderate anti-Trypanosoma brucei brucei activity and a very high anti-Trypanosoma congolense activity in vitro suggesting the presence of some non-specific materials.Authors’ SummaryThe mechanisms that allow trypanosomiasis-resistant animals to control blood trypanosomes are being investigated, to identify non-specific factors that kill trypanosomes or limit their proliferation, contributing to host resistance. For instance, xanthine oxidase has been isolated and identified as the protein that kills trypanosomes in Cape buffalo. Humans and several other primates are also known to be resistant to infection by several animal-specific trypanosome species. In this study, sera from some zoo primates, red patas monkey and tantalus monkey, tested on Trypanosoma brucei brucei and Trypanosoma congolense in vitro, showed a slight anti-Trypanosoma brucei brucei activity and a very high anti-Trypanosoma congolense activity. These activities were shown to be cidal in nature and not associated with the protein xanthine oxidase. The authors suggest that non-specific factors other than the enzyme xanthine oxidase might have accounted for the sera anti-trypanosomal activities.
