2)
Todd Hewitt Broth is used for the cultivation of fastidious streptococci. The broth contains beef heart infusion and other other compounds to enable fastidious organisms to grow.
|
This media is enriched against fastidious streptococci. |
||
|
This media is enriched for fastidious streptococci. |
||
|
This media selects against non-fastidious streptococci. |
Homework Answers
- Option D) Sabouroud glucose agar is a selective medium for filamentous fungi and yeast. Due to high pH (pH 5) it inhibits the growth of bacteria. Added chloramphenicol acts as a bactericidal agent that further inhibits the growth of bacterium allowing only the growth of fungi on the medium. Therefore, this is the correct option.
- Option B) Todd Hewitt Broth is a recommended medium for the growth of antigenic streptococci. Components like beef heart infusion and peptones are required for its growth. The presence of dextrose stimulates the production of streptococcal antigen. Therefore, this is the correct option.

Introduction: Selective and differential media are used frequently in Microbiology Pathology Labs to identify a known group of bacteria from a complex mix of other bacteria. The medium is designed to select against as many of the background organisms as possible by using a medium in which they will not grow but the organisms under investigation can grow hence the "Selective" part of the name.

NEISSERIA EXPERIMENT MICROBIOLOGY LAB (Revised March 2016) Background There are two main pathogens in the genus Neisseria: N.gonorrhoeae and N meningitidis, along with many species which are normal flora for mucus membranes like the nasopharynx, vagina, urogenital tract, etc. In order to diagnose gonorrhea in a male, a Gram stain of the urethral discharge should reveal Gram negative diplococci and many white blood cells. This is considered sufficient grounds to treat for gonorrhea. In a female, diagnosis must be based...

Clinical
history: An HIV positive male presented in clinic with
confusion and disorientation. He had a fever 38.5°C and
photophobia. His CD4 T cell count was 80/ul. An MRI and lumbar
puncture were performed. The MRI showed various small lesions
within the brain. CSF analysis indicated 32 White Blood Cells/ul
with 89% lymphocytes, and 6% monocytes, glucose of 22mg/dl, and
protein of 89mg/dl. Gram stain showed yeast and India ink negative
stain showed a thick capsule.
