An extreme form of diarrhea c. Severe dehydration d. Pus-filled e. both a and d 3. Fill in the blank: This pathogen causes gas-gangrene: 4. The genus Clostridium is the causative agent of: a. Botulism b. Tetanus c. Colitis d. Gangrene e. all of the above 5. Bacillus is: a, Gram negative b. An endospore former c. Aerobic d. both b and c e. all of the above 6. Fill in the blank: 95% of this genus has penicillinase: 7. Fill in the (2) blanks: An acid-fast stain identifies this genus: Mycobacteria; a positive reaction for this bacteria would 8. True/False: A furuncle may be unsightly, but it's still better than a carbuncle. 9. A patient presents the following symptoms: fever, headache and dizziness. She also has a red, circular rash-like skin reaction on her calf, resembling a "bull's eye." What pathogen would you suspect? (a) and what disease does this pathogen cause? (b): a. Borrelia burdorferi b. Lyme disease 10. Rickettsia rickettsii is the causative agent for: a. Lyme disease b. Ricketts c. J. Denver disease

Answer 1

1. Stapylococcus Aureus is the most resistant forms of all non-spore forming pathogens, even it is Methicillin-Resistant

2. Pyogenic means pus -filled and not the fever causing, the fever causing is pyrogenic. hence only option d is correct.

3.Clostridium perfringens bacteria is the pathogen which causes gas gangrene

4. Option E is correct as genus clostridium is the causitive agent of all mentioned. like

Clostridium difficile: colitis

Clostridium perfringens: gangrene

clostridium botulinum: botulism

clostridium tetani: tetanus

5. Generally bacillus are gram positive, but some are gram negative, these are areobic and endospore forming agents. Hence option E is correct.

6. 95% of staphylococcus genus has penicillinase

7.The positive acid fast reaction for mycobacterium would be red colored.

8. Statement is true as a furuncle may be slightly but it is still better than a carbuncle, as carbuncle is most painful filled with pus and fever causing.

9.These are the symptoms of the typical lyme disease.

10.Rickettsia rickettsii is the causative agent for Rocky Mountain spotted fever

as lyme disaese is caused by Borrelia burgdorferi,  Rickets is bone disorder caused by deficiency of vitamin D, J. Denver disease is caused by Yersinia pestis
