MLS 341 Lecture Notes - Lecture 5: Bacillus Cereus, Abdominal Pain, Eschar
Document Summary
Objectives: upon completion of this lesson, the student will be able to: Describe the general characteristics of bacillus anthracis, including its colonial morphologic characteristics and gram-stain appearance. Medium, large, gray, flat, irregular with swiriling projections, ground glass appearance. M1:35:s:1 state the location of the organisms in the natural environment, and list the modes of transmission as they relate to human infections. Soil, found in wild domestic animals(herbavores) cows, sheep, goat, horse: injection: heroin, animal skins (hides), leison. M1:35:s:2 describe the four forms of b. anthracis infection, including source, route of transmission, and signs and symptoms. M1:35:s:3 summarize the types of infections associated with b. cereus. Food poisoning, diarrheal which is characterized by abdominal pain and watery diarrhea or emetic type which is manifested by vomiting. M1:35:s:4 outline the laboratory tests used to differentiate b. anthracis from other bacillus species. B. anthracis: multilocus sequence typing (mlst), anaerobic growth, voges proskauer, indirect hemagglutination and enzyme linked immunosorbent assys detect antibodies.
