Primates in the Deng Deng National Park such as the endangered Gorillas and Chimpanzees are likely to suffer the effect of Zoonosis (transfer of diseases from humans to animals and vice versa). This is so due to the high encroachment into wildlife habitat. The life cycle and mode of transmission of intestinal parasites increase the chances of cross host infection between phylogenetically related or non-related species and re-infection of species. In particular, the serious threat that parasites can impose on endangered wildlife species is increasingly recognized, as it is important in preserving biodiversity in wildlife ecosystems and controlling the emergence or re-emergence of diseases. Sensitisation and mind set change is of great importance in the communities around the Deng Deng National Park to secure the future of primates and prevent the outbreak of diseases.
Human encroachment into wild life habitat may increase rates and severity of parasitism via the direct route of cross-host transmission between phylogenetically related species (Preslar, 1998) and in some instances non phylogenetically related species (Linda, 2013).
Many species of wildlife today, inhabits relatively small areas because the vast forest that existed in the past has been destroyed by human activities and as a consequence, diseases appear to be more common in wild populations (Kock, 1995; Lilly et al., 2002 and Gillespie et al., 2008). To support this fact, a survey of emerging pathogens in wildlife was conducted in North America by Dobson and Foufopoulos in 2001and they found out that human involvement facilitated 55% of pathogen outbreaks.
More so, 233 critically endangered species listed by the IUCN, were alleged threatened by infectious diseases (Smith et al., 2006). These diseases are regarded as the cause of fluctuation or decline in biological population (Macphee and Greenwood, 2012). Wildlife diseases have historically gained attention primarily when they were considered a threat to agricultural systems and the economic, social, or physical health of humans (McCallum and Dobson, 1995; Holmes, 1996; Daszak et al, 2000). These parasites may be very important to determine the host-health and show significant influence on survival and reproduction of populations (Scott 1988; Lewis et al. 2002; Roberts & Janovy 2008).
