Wits study finds many unknown microbes in wild lion guts
Researchers at the University of the Witwatersrand (Wits) studied the gut microbes of wild lions in Namibia's Etosha National Park. They reconstructed 318 bacterial and 102 viral genomes from 23 faecal samples taken from 20 lions.
Most of the genomes differed enough from those in international databases to suggest largely new species. Carl Belger, who did the work for his Master's at Wits, is the lead author. The paper appears in the peer-reviewed journal Animal Microbiome. Adding the new genomes to the database cut unclassified DNA reads from 24.5% to 4.5%. The sample was small, from one park, and the study could not compare prides, sexes or life stages.
