Homework Answers
1) OPTION B - SAPROPHYTES
Saprophytes are the living organisms that live and feed on dead and decaying organisms
they break downthe complex organic matter into simpler substances that are taken up by the plants for various metabolic activities
2) OPTION D- PURPLE
Gram-positive bacteria have a thick mesh-like cell wall made of peptidoglycan (50–90% of cell envelope), and as a result are stained purple by crystal violet, whereasgram-negative bacteria have a thinner layer (10% of cell envelope), so do not retain the purple stain and are counter-stained pink
3) OPTION C - PATHOGEN
A disease causing organism or agents are called pathogens.
4) OPTION C - Antimicrobial
living tissue - anti microbial
non living things - Antiseptic
5)OPTION C - BACILLI
COCCI - spherical
spirilla - spiral
sphirochete- thin thread like
6) OPTION B - FACULTATIVE ANAEROBES
Facultative anaerobes are organisms that thrive in the presence of oxygen but also grow in its absence by relying on fermentation or anaerobic respiration
7)OPTION D- RICKETTSIA
rickettsia are the microorganism transmitted through ticks
8)OPTION C - STREPTOCOCCUS PYOGENES
9) OPTION D - BORELLIA BURGDORFERI
10) ALL OF THE ABOVE

Case Study
#1
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.
