Project description:Mycoplasma hominis (M. hominis) belongs to the class Mollicutes, characterized by a very small genome size, metabolic pathway reduction, including transcription factors, and the absence of a cell wall. Despite this, they adapt well not only to specific niches within the host organism but can also spread throughout the body, colonizing various organs and tissues. The mechanisms of adaptation in M. hominis, as well as the pathways regulating them, are poorly understood. It is known that when adapting to adverse conditions, mycoplasmas can undergo phenotypic switches that may persist for several generations. To investigate the adaptive properties of M. hominis associated with survival in the host organism, we conducted a comparative proteogenomic analysis of 8 clinical isolates of M. hominis obtained from patients with urogenital infections, along with the laboratory strain H-34.
Project description:description Blastocystis sp. is a highly prevalent anaerobic eukaryotic parasite of humans and animals. The genome of several representatives has been sequenced revealing specific traits such as an intriguing 3’-end processing of primary transcripts. We have acquired a first high-throughput proteomics dataset on the difficult to cultivate ST4 isolate WR1 and detected 2,761 proteins. We evidenced for the first time by proteogenomics a functional termination codon derived from transcript polyadenylation for seven different key cellular components.
