Use NCBIlink to find] While B. cereus is associated mainly with food poisoning, it is being increasingly reported to be a cause of serious and potentially fatal non-gastrointestinal-tract infections. Authors thank the Department of Biosciences and Bioengineering, IIT Guwahati for the valuable support. Two out of the five B. licheniformis isolates were correctly identified by biochemical or MS analysis. A nonhemolytic, nonmotile Bacillus, suspicious of Bacillus anthracis, was isolated from a blood culture. We discuss the evaluation that led to the final identification of the bacterium as … Nonhemolytic, nonmotile gram-positive rods indicative of Bacillus anthracis Emerg Infect Dis. Bacillus licheniformis, also known as B. licheniformis, is a spore bacteria, much like other Bacillus species. belonging to a recognized group of disease-invoking agents in humans or animals and having an 1: Bacillus megaterium A species of bacteria whose spores vary from round to elongate. The external layer of the spores produced by Bacillus species, such as B. megaterium, B. anthrax, and B. cereus, is called an exosporium, and is composed of a number of different proteins that play a major role in the spore's attachment to surfaces (Wood and Waites 1988; Stewart 2015). Plates are incubated at 30 °C. nat.) The culture liquid was then centrifuged at 2152×g for 3 min to collect bacteria cells.
