The SleB protein is one of two redundant cortex-lytic enzymes (CLEs) that initiate the degradation of cortex peptidoglycan (PG), a process essential for germination of spores of Bacillus species, including Bacillus anthracis. SleB has been characterized as a soluble lytic transglycosylase that specifically recognizes spore cortex PG and catalyzes the cleavage of glycosidic bonds between N-acety...

background: bacillus anthracis may usually cause three forms of anthrax: inhalation, gastrointestinal and cutaneous. the gastrointestinal (gi) anthrax develops after eating contaminated meat. thus, in this paper were report 5 cases of intestinal anthrax. case presentation: we report a case series of intestinal anthrax, with history of consumption of raw or poorly cooked liver of sheep. one pati...

Concludes that conditions during sporulation play significant role in Bacillus anthracis sporulation. Various factors namely temperature, pH and nutrient deprivation were found to bring about changes in sporulation efficiencies of B. anthracis cultures. B. anthracis spores formed under various stress conditions have varied suceptibility towards physical and chemical denaturants used for spore i...

background & aim: salvia officinalis is known as a traditional medicine for several diseases in countries like lebanon, syria, jordan, etc. in addition, s. officinalis has been subjected to several studies in a try to specify its medicinal effects. this study aims to evaluate the antimicrobial activity of this plant. the aim of the present research was to study antibacterial effects of s. o...

INTRODUCTION Bacillus anthracis is the causative agent of anthrax, a disease endemic in regions of Northern Cape Province and Kruger National Park of South Africa. Accurate identification of virulent B. anthracis is essential but challenging due to its close relationship with other members of B. cereus group. This study characterized B. anthracis and Bacillus species that were recovered from an...

Cathelicidins are a family of cationic peptides expressed in mammals that possess numerous bactericidal and immunomodulatory properties. In vitro analyses showed that human, mouse, and pig cathelicidins inhibited Bacillus anthracis bacterial growth at micromolar concentrations in the presence or absence of capsule. Combined in vitro analyses of the effects of each peptide on spore germination a...
