Paleomicrobiological investigations of a 14(th)-century coprolite found inside a barrel in Namur, Belgium were done using microscopy, a culture-dependent approach and metagenomics. Results were confirmed by ad hoc PCR - sequencing. Investigations yielded evidence for flora from ancient environment preserved inside the coprolite, indicated by...
The oral fluid microbiome comprises an important bacterial diversity, yet the presence of archaea has not been reported so far. In order to quest for the presence of methanogenic archaea (methanogens) in oral fluid, we used a polyphasic approach including PCR-sequencing detection, microscopic observation by fluorescence in-situ hybridization,...

Chronic tropical cutaneous ulcers remain a neglected medical condition in West Africa, particularly Buruli ulcer, which is caused by mycolactone cytotoxin-secreting Mycobacterium ulcerans ( M . ulcerans ). Medical management of this highly debilitating and necrotising skin infection may be modified by colonisation and co-infection of the ulcer...
ABSTRACT Mycobacterium ulcerans , the opportunistic pathogen causing Buruli ulcer, is reported to affect rural populations in 36 tropical countries. We report one case of Buruli ulcer in a peri-urban area in Côte d'Ivoire, confirmed by whole genome sequencing which indicated a M. ulcerans genotype previously unreported in Côte d'Ivoire.
