Impact of parasite infections on the gastrointestinal microbiota of free-ranging western lowland gorillas
Original language description
The impact of parasite infections on mammalian gastrointestinal microbiota (GIM) is widely discussed topic. The relationships between pathogenic microorganisms and commensal bacteria are crucial for good development and functioning of gut immune system. Resident GIM products may strongly interfere with the survival and the physiology of many parasites and, consequently, with the outcome of many parasitic infections. However, gastrointestinal parasites (GIP), both protozoans and helminthes, constantly excrete and secrete molecules that may change the environment determining alternations in GIM composition. These changes can be either beneficial or harmful for the host. Here, as for the first time, we investigate the effect of GIP infection on GIM composition in two habituated and two unhabituated groups of wild western lowland gorillas (Gorilla g. gorilla) from the Dzanga Sangha Protected Areas, Central African Republic. We coproscopically examined 64 fecal samples for GIP and determined the levels of strongylid nematodes. We characterized GIM composition through 454 pyrosequencing of the bacterial 16S rRNA gene. The comparison of GIM profiles of individuals from four different groups indicated that the relative abundance of specific bacterial taxa significantly differ as well as the intensity of strongylid infections among groups. However, our results suggest that differences in GIM composition of studied groups are not induced by GIP infections. Other factors shaping the GIM will be discussed.
