thirty isolates of bacillus anthracis recovered from animal carcasses, soil and human in different localities in iran between 2007 and 2008. they were tested by standard disc diffusion susceptibility method for their resistant/ susceptibility to different kinds of antibiotics. according to american national committee of clinical laboratory standards (nccls) guidelines all isolates were sensi...

background: dna immunization with plasmid dna encoding bacterial, viral, parasitic and tumor antigens has been reported to trigger protective immunity. objective: to evaluate the use of a dna immunization strategy for protection against anthrax, a plasmid was constructed. methods: the partialsequence of protective antigen of bacillus anthracis, amino acids 175-764, as a potent immunogenic targe...

Phosphatidylinositol-specific phospholipases (PI-PLCs) are virulence factors produced by many pathogenic bacteria, including Bacillus anthracis and Listeria monocytogenes. Bacillus PI-PLC differs from Listeria PI-PLC in that it has strong activity for cleaving GPI-anchored proteins. Treatment of murine DCs with Bacillus, but not Listeria, PI-PLC inhibited dendritic cell (DC) activation by TLR l...

to isolate and detect anthrax spores form soil in different regions of iran in order to find the anthrax foci‚ a total of 668 environmental specimens were collected during 2003-2004. bacterial endospores were extracted from soil specimens via flotation in distilled water, incubation at room temperature, filtration, heat shock and culture on blood agar and selective plet media. bacillus anthraci...

Rapid and accurate detection of Bacillus anthracis, the causative agent of anthrax, remains an active area of research due to the continued threat of bioterrorist attack. The ability to differentiate Bacillus anthracis spores from spores belonging to other Bacillus species is important for the development of spore-based detection methods. Furthermore, not all Bacillus anthracis strains are full...

Bacillus anthracis shares many regulatory loci with the nonpathogenic Bacillus species Bacillus subtilis. One such locus is sinIR, which in B. subtilis controls sporulation, biofilm formation, motility, and competency. As B. anthracis is not known to be motile, to be naturally competent, or to readily form biofilms, we hypothesized that the B. anthracis sinIR regulon is distinct from that of B....

Anthrax, caused by Bacillus anthracis, is a fatal disease and all the warm bloodedanimals are susceptible to this disease. Many livestock populated areas in Pakistan endemic forAnthrax (Thappa Karthikeyan 2001), therefore population annually vaccinatedagainst Anthrax. Veterinary Research Institute (VRI) has been producing Anthrax Spore Vaccine(ASV) for couple of decades. The current study was d...

Bacillus anthracis is the causative agent of fatal anthrax in both animals and humans. It is prevalently pathogenic. Here, we present a Bacillus anthracis PFAB2 strain from a relatively unexplored Panifala hot water spring in West Bengal, India. It is nonpathogenic, exopolysaccharide producing, and thermotolerant in nature.

Decontamination of bacterial endospores such as Bacillus anthracis has traditionally required the use of harsh or caustic chemicals. The aim of this study was to evaluate the efficacy of a chlorine dioxide decontaminant in killing Bacillus anthracis spores in solution and on a human skin simulant (porcine cadaver skin), compared to that of commonly used sodium hypochlorite or soapy water decont...

There continues to be a need for developing efficient and environmentally friendly treatments for Bacillus anthracis, the causative agent of anthrax. One emerging approach for inactivation of vegetative B. anthracis is the use of bacteriophage endolysins or lytic enzymes encoded by bacterial genomes (autolysins) with highly evolved specificity toward bacterium-specific peptidoglycan cell walls....
