Summary Introduction
To determine:
The reason that even though Clostridium is strictly an anaerobic bacterium, it can be isolated easily from the exposed surface of the skin.
Introduction:
Clostridium is a Gram positive, obligate anaerobe that reproduces by forming rod shaped vegetative cells. Species of Clostridium inhabit soil and gastrointestinal tract of many animals but normally it is an inhabitant of reproductive tract of healthy women.

About becterial enzymes, it is CORRECT to affirm that:
a). Some becterial enzymes can help the microbe fight the immune system, by destroying lgA.b). Coagulases are enzymes that use the host's fibrinogen and form a semi-solid get that isolates amd protects the bacteria.c). Some bacterial enzymes such as hyaluronidase can help the microble move through the host's tissus by destroying the tissue's components.d). Fibrolysin is an enzymes that can help from blood clots.
Why is Salmonella typhi a gram negative bacilli? Explain.

- Propionibacterium acnes is a normal member of the skin microbiome that benefits the body by lowering the skin's pH- an antimicrobial effect. However, P. acnes is also the leading cause of acne.

It produces metabolic byproducts that give soil a musty smell as well as some that can be used as antibiotics. Which of the following genera is being described? View Available Hint(s) for Part A Pseudomonas Campylobacter Neisseria Streptomycesarrow_forwardIdentifying an unknown bacterium is an essential step in the diagnosis and treatment process. Since not every antibiotic is effective against every type of bacteria, knowing what caused a particular infection allows us to make correct prescriptions so patients can recover more quickly. Knowing the cause of an infection also prevents antibiotic resistance as well, since incorrect prescriptions allow bacteria to be unnecessarily be exposed to antibiotics, increasing the chances of developing resistance.arrow_forward
