Memoirs of a gut bacterium

Metabolic niche of a prominent sulfate-reducing human gut bacterium.

Sulfate-reducing bacteria (SRB) colonize the guts of ∼50% of humans. We used genome-wide transposon mutagenesis and insertion-site sequencing, RNA-Seq, plus mass spectrometry to characterize genetic and environmental factors that impact the niche of Desulfovibrio piger, the most common SRB in a surveyed cohort of healthy US adults. Gnotobiotic mice were colonized with an assemblage of sequenced...

Mosquito Gut Bacterium May Curb Malaria

Before Plasmodium falciparum, the most important human malaria parasite, can infect people, it must first infect its mosquito host. But that’s not always so easy to do, according to a team of researchers from the Johns Hopkins University Bloomberg School of Public Health and the Malaria Institute at Macha in Zambia. The team reports that a bacterium naturally found in mosquitoes produces a shor...

“Ihubacter massiliensis”: a new bacterium isolated from the human gut

We report here the main characteristics of "Ihubacter massiliensis," strain Marseille-P2843(T) (CSUR P2843), a new genus of the Clostridiales family isolated from a stool sample from a healthy 29-year-old woman.

‘Culturomica massiliensis’, a new bacterium isolated from the human gut

We report here the main characteristics of 'Culturomica massiliensis', strain Marseille-P2698(T) (CSUR P2698) a new genus isolated from the stool specimen in a 66-year-old man.
