Many prokaryotes are covered by a two-dimensional array of proteinaceous subunits. This surface layers (S-layer) is incompletely characterized for many microorganisms. Here, we studied Bacillus cereus AH187. A genome analysis identified two genes enc

Summary The human-adapted organism Neisseria gonorrhoeae is the causative agent of gonorrhoea, a sexually transmitted infection. It readily colonizes the genital, rectal and nasalpharyngeal mucosa during infection. While it is well established that N

We report the sequence of the Streptococcus pyogenes emm28 strain M28PF1, isolated from a patient with postpartum endometritis. The M28 protein is smaller than that of MGAS6180 (NC_007296.1). Furthermore, the 1,896,976-bp-long chromosome presents, co

International audience; Bacillus anthracis toxin gene expression requires AtxA, a virulence regulator that also activates capsule gene transcription and controls expression of more than a hundred genes. Here we report that atxA mRNA is 2.7-kb-long an

Publikováno v: Microorganisms, Vol 8, Iss 12, p 1864 (2020)

Anthrax is a highly resilient and deadly disease caused by the spore-forming bacterial pathogen Bacillus anthracis. The bacterium presents a complex and dynamic composition of its cell envelope, which changes in response to developmental and environm
