1. For bacterium 1 and 4 , Ampicillin 10 ug is best
For bacterium 2, Vanomycin 30 ug and chloramphenicol 30 ug are best
For bacterium 4, Tetracycline 20ug is best
2. The diameter of the zone around the bacterium is an essential parameter to determine the resistance of the bacterium. This simply defines that isolated bacterium can not be inhibited by normal dosage schedules of antibiotics

An antibiotic sensitivity test was performed for S. aureas, B.
cereus, E coli and S. typhimurim. The antibiotics used are
Gentamycin (GM), Chloramphenicol (C), Streptomycin (S), Ampicillin
(AM), Tetracycline (TE) and Erythromycin (E). The diameters of the
zones of inhibition were measured for each antibiotic and recorded.
S = susceptible. R = resistant. I = intermediate. Do the results
align with the expected results for each organism?

A clinical researcher performed a modified Kirby-Bauer assay on a bacterium cultured from a patient. The following is a summary of the assay performed: The clinician spread the surface of several Mueller-Hinton agar plates (a media type containing beef extract, casein, and starch) with the bacterial culture using aseptic technique. Next, they applied sterile antibiotic disks, each containing a different antibiotic to the surface of the plates. After the agar plates were incubated overnight, the clinician measured the diameter of...

Unfortunately, within a few hours of her ruptured appendix diagnosis, Tara started to experience tachypnea, tachycardia, altered mental status, and hypotension. Her earlier blood-test results showed elevated white blood cells and other inflammatory markers, as well as an electrolyte imbalance. She also had mild pyuria, or pus in the urine. Tara's new signs all suggested she had developed sepsis, but the blood cultures wouldn't be back for a few more days and, in most cases of sepsis, those tests are...
