Abstract

Research on sub-Saharan African elephant (Loxodonta aji'icana) parasites and their diversity is especially limited in wild populations. Fourteen fecal samples were collected from semi-wild ( orphaned) and wild African elephants seven months to seven years old from Lilayi and Kafue National Park. Fecal examinations revealed the presence of strongylids, paramphistomes, and ciliates in these animals. Parasite numbers based on eggs per gram (EPG) counts were low in elephants less than three years old, while elephants between the ages of three and ten appeared to have higher parasite burdens based on fecal egg shedding. Fecal samples from wild elephants had similar egg counts as those from semi-wild elephants of similar age. These semi-wild elephants had apparently low parasite loads and no apparent clinical signs from their infection, suggesting that routine deworming in this population was unnecessary. Genera and species of strongyles and paramphistomes were unable to be determined based on egg morphology alone. The measurements of strongylid eggs recovered in this study were within the published ranges for such eggs of several genera and species of African elephant parasites. However, measurements of recovered paramphistome eggs were below published size ranges.
