The pathogen causing tuberculosis is mycobacterium tuberculosis. The structure of this bacteria includes mycolic acid and a key characteristic of these long fatty acids is that it resists gram staining. Rose Bengal stains borders of herpes simplex and also aids in visualizing dead devitalized cells in the conjunctiva & cornea.IncorrectD. Acid fast staining

6. Question
Which organism is responsible for causing a positive venereal disease research laboratory test?
CorrectD. Treponema pallidum is the organism responsible for causing syphilis and is detected using a venereal disease research laboratory testing. Toxoplasma gondii is tested using IgG immunological testing. Neisseria gonorrhoeae is found by a simple urine test and may be detected with a Thayer-Martin chocolate agar stain.

7. Question
What is the MOST common microorganism that causes glomerulonephritis?
CorrectA. Streptococcus Pyogenes. Remember this gram positive organism is beta-hemolytic meaning it has full hemolysis potential.It is classified as very opportunistic, breaking through the skin and secreing both endotoxins and exotoxins.
Staph aureus is the most common cause of blepharitis. Remember this organism is gram positive with features of being both catalase positive and coagulase positive. All other options are not microorganisms
Staphylococcus Epidermidis is the most common cause of postoperative endophthalmitis. Remember this organism is gram positive with features of being catalase positive but coagulase negative.IncorrectA. Streptococcus Pyogenes.
