Bacteria that are obligate intracellular pathogens of humans are considered to be Autotrophs Heterotrophs Photosynthetic Hyperthermophiles Chemolithotrophs Which of the following statements best describes the pathogenesis of Clostridium botulinum? It elaborates an exotoxin that is a lecithinase that causes tissue necrosis. It elaborates a toxin that suppresses the release of inhibitory neurotransmitters. It produces a polysaccharide capsule that inhibits phagocytosis and contributes to invasion of the central nervous system. It elaborates a toxin that inhibits the release of acetylcholine at cholinergic synapses. It produces a leukotoxin that leads to abscess formation.

Consider a gram-negative pathogen isolated from marine mammals. This pathogen is subjected to a series of tests and found to have the following characteristics: oxidase-positive, does not hydrolyze urea, produces indole, does not produce acetoin. Which of the following could it be? O Pasteurella mulocida O Klebsiella pneumoniae O Yersinia enterocolitical O Mannheimia haemolytica
clostridium botulinum is a bacterium usually present in soil that may cause botulism. Briefly explain why one or few cells of a pathogenic bacterium, such as clostridium botulism, by itself typically does not secrete a toxin, despite the species as a whole being characterized as toxin producing.

OOOOOP All of the following are true about gas gangrene EXCEPT: Caused by the anaerobic bacterium Clostridium perfringens The etiologic agent stays confined to the site of initial infection and does not damage or invade other tissues Infection is caused by endospores from the soil or other environmental sources Begins with interruption of blood supply to tissue, causing cell death The etiologic agent ferments carbohydrates, producing CO2 and H2
During a recent morbidity report at your local hospital, you noted a 50 year old firefighter recovering from smoke inhalation and severe burns received on the job. While recovering from a skin graft, the patient developed sudden and severe upper right quadrant pain accompanied by fever, nausea and vomiting. An abdominal ultrasound demonstrated Murphys sign along with gas in the gallbladder. Escherichia coli Alcaligenes faecalis Bacillus megaterium Bacillus cereus Citrobacter freundii
Haemophilus influenzae must be grown on special blood agars, e.g. chocolate agar, which is blood agar treated with heat to release gorwth factors and to destroy inhibitory enzymes. Thus Haemophilus is described as fastidious oxygen-sensitive oxygen labile voracious
holsappleeus scarius is a normal flora of the human intestenal tract. its facultative anaerobe capable of catabolizing carbohydrates. which conditions will give them the most growth?
Name two methods of control of growth for Mycobacterium tuberculosis pathogen in a patient with the disease and when confronted with the pathogen outside of the host. Be careful to specify if it is a physical method or a chemical method (check lecture to differentiate these two). Control of growth means how would you deal with an infection related to a person as well as how would you minimize the presence of the bacteria on a surface or object.
