We describe here the isolation and characterization of a major albumin from the seeds of Cereus jamacaru (Cactaceae), to which we gave the trivial name of cactin. This protein has a molecular mass of 11.3 kDa and is formed by a light chain (3.67 kDa) and a heavy chain (7.63 kDa). This protein was
Proteases have prospective financial and environment-friendly applications; hence attention is focused currently on the finding of new protease producing microorganism so as to meet the requirements of industry. A thermophilic bacterial strain producing extracellular protease activity was isolated
The factors involved in the pathogenesis of Bacillus cereus (B. cereus) in non-gastrointestinal diseases are poorly investigated. Some researchers suggest that B. cereus proteases may be involved in these illnesses. The aim of this work was to purify and characterize a protease isolated from a
OBJECTIVE
To study clinical characteristics and resistance of wound surface infections, so as to guide clinical diagnosis and rational administration.
METHODS
The clinical setting and laboratory results were collected by analyzing 20 strains of Bacillus cereus isolated from clinical samples in
Bacillus cereus, a food poisoning bacterium closely related to Bacillus anthracis, secretes a multitude of virulence factors including enterotoxins, hemolysins, and phospholipases. However, the majority of the in vitro experiments evaluating the cytotoxic potential of B. cereus were carried out in
The growth of Bacillus cereus was markedly inhibited by the addition of lactoferrin and was recovered by the addition of FeCl3. The growth inhibition was also reversed by the addition of erythrocytes and hemoglobin. B. cereus can use heme or heme-protein complex (hemoglobin-haptoglobin and
Trypsin-like enzymes were studied in dormant, activated, and germinated spores of Bacillus cereus T. Dormant spores contained two heat-labile enzyme activities. One was extractable with 2 M KCl and hydrolyzed azo-albumin. The second, a trypsinlike activity, was not extractable with 2 M KCl and
B. cereus can use hemoglobin, heme, and heme-albumin complex as iron sources, but does not use other iron binding proteins such as transferrin and lactoferrin. B. cereus digests heme-protein complexes and elicits heme release from the proteins, but does not digest transferrin and lactoferrin.
The immunoreactivities of hydrogen fluoride (HF)-released cell wall polysaccharides (HF-PSs) from selected Bacillus anthracis and Bacillus cereus strains were compared using antisera against live and killed B. anthracis spores. These antisera bound to the HF-PSs from B. anthracis and from three
OBJECTIVE
The purpose of this study was to determine to what extent blood-retinal barrier (BRB) permeability occurred during experimental Bacillus cereus endophthalmitis and whether tight junction alterations were involved in permeability.
METHODS
Mice were intravitreally injected with 100
In recent years, plasma activated water has attracted more attention as a new disinfectant. The purpose of this study was to explore impact of variation of different treatment conditions on the inactivation kinetics of Bacillus cereus spores by PAW. All survival curves showed that the number of
