AMT MLS Microbiology Study Questions Correctly
Answered
Entamoeba Hartmann is most commonly recovered from: - Answer Stool
The disappearance of HBsAg and HBeAg, the persistence of total anti-abc, the appearance of ant-has,
and often the presence of anti-Be indicates what type of Hepatitis infection? - Answer Recovery phase of
HBV infection
What organisms are the appropriate stock cultures for quality control testing of oxidase production? -
Answer Escherichia coli / Pseudomonas aeruginosa
These symptoms relate to what diagnosis?
- abdominal cramps
- Fever
- Diarrhea
- Vomiting
- Abdominal Tenderness
- Fatigue
- Excessive gas
- Rectal pain while having a bowel movement
- Unintentional weight loss
- Bloody stool 15-20 per day - Answer Intestinal amebiasis
Which of the following organisms is the most common cause of acute cystitis? - Answer Escherichia coli
Tiny translucent gray colonies were recovered on blood agar from a patient with purulent conjunctivitis.
Gram negative diplococci were seen on Gram stain. The preparation illustrated in this photomicrograph
was obtained from colonies growing at the margin of inhibition of a 10 µg/mL penicillin disk. The most
likely identification is: - Answer Moraxella lacunata
, a normal flora of the mouth and those that have been in an altercation and have punched someone in
the mouth, can often become infected with this bacteria. - Answer Eikenella corrodens
a sexually transmitted infection that can cause acute urethritis in males and cervicitis in females, as well
as pharyngitis, conjunctivitis, anorectal infections, and some disseminated infections as well. This
organism is not part of the normal human flora. - Answer Neisseria gonorrhoeae
part of the normal skin flora of many individuals, does not cause clenched-fist cellulitis. S. aureus has
been isolated from other cellulitis infections and is also the causative organism in scalded skin - Answer
Staphylococcus aureus
part of the normal oral and GI flora, are viridans streptococci. This group may group with Lancefield
groups A, C, F, G or L and have been associated with abscesses and bacteremia caused by invasive
pyogenic infections. - Answer Streptococcus anginosus group
a tissue stain that is used specifically to detect Histoplasma capsulatum in blood and bone marrow. The
fungal elements will appear as purple-to-blue yeast with a clear halo (indicating the presence of a
capsule). - Answer Giemsa
a tissue stain used to detect any fungal elements present in a sample. Fungal elements appear magenta
in color in comparison to the background material which appears pink or green. - Answer Periodic acid-
Schiff
a tissue stain used to identify the presence of phaeoid fungi, which contain melanin in their cell wall,
that binds with the stain and appear brown in comparison to the background material which appears
pink-purple. - Answer Fontana-Masson
used to detect fungal elements that are embedded in skin, hair, nails, and tissue. The stain binds to
polysaccharides present in the chitin of fungus which will appear apple green to blue-white depending
on the filters used when reading the slide on a fluorescent microscope. - Answer Calcofluor white
Bacterial species commonly associated with wound infections following a dog bite - Answer
Staphylococcus intermedius, Pasteurella multicida, and Capnocytophaga cynodegmi
