Microorganisms - answers-Bacteria, fungi, and rickettsiae are all microorganisms.
Escherichia coli - answers-In the scientific name Escherichia coli, the name coli indicates the
species.
Sensitivity testing - answers-Sensitivity refers to a test to determine the organism's
susceptibility to certain antibiotics.
Helminth infection diagnosis - answers-Diagnosis of a helminth infection requires a stool sample
for ova and parasite examination.
Pathogenic organisms viability - answers-Most pathogenic organisms remain viable at
temperatures of 37°C.
Pure culture - answers-The growth of only one microorganism on a nutrient surface or culture.
Facultative anaerobe - answers-An organism that is flexible as far as its oxygen requirements
are concerned.
Spirochetes - answers-Tightly coiled, spiral-shaped bacteria are called spirochetes.

, Rickettsiae - answers-A tiny, Gram-negative organism transmitted by blood-sucking insects.
Treponema pallidum - answers-An organism that is unlikely to be transmitted by airborne
droplets.
Clostridium botulinum - answers-An organism that is unlikely to be transmitted by sexual
contact, typically transmitted by contaminated food.
Gram-positive bacteria staining - answers-Blue/Violet indicates Gram-positive bacteria.
Gram reaction - answers-The Gram reaction a bacterium exhibits is the result of its chemical
makeup of the cell wall.
In vitro - answers-The term which means 'in glass' or 'in the laboratory' because it is not
occurring in a living body.
Fungi classification - answers-Fungi are classified as eukaryotes.
Staphylo- prefix - answers-The prefix staphylo- means that bacteria appear in grapelike clusters.
Pneumocystis pneumonia - answers-An infection caused by a fungus.
Beta hemolysis - answers-Is best detected on a sheep's blood medium, caused by hemolysis of
blood cells, refers to a clear zone around bacterial colonies growing on a sheep's blood medium.
Antibiotic effectiveness - answers-The microbiology laboratory report for Mrs. Wallace's urine
culture lists eight antibiotics, five of which are followed by the letter 'S,' meaning these
