Question

plllzz Compare your throat culture plate to that of your partner. How are the colonies similar, and what does this indicate about normal upper respiratory flora? If you wanted to screen a population for the presence of MRSA, would you use SM110 or MSA?, Explain. Would you expect a coliform to grow on BAP? Why or why not?. When screening for beta streptococci, some microbiology laboratories set up a phenylethyl alcohol (PEA) agar plate, which contains ethanol but does not have blood, in addition to BAP. Why is this included?

Explanation / Answer

olonization refers to the presence of microorganisms in or on a host with growth and multiplication, but without tissue invasion or damage. In the case of MRSA, the body site most commonly colonized is the anterior nares.[1] Other body sites that may be colonized with MRSA include open wounds, the respiratory tract, perineum, upper extremities, umbilicus (in infants), urinary tract, and axilla. VRE colonization is generally in the stool. MRSA or VRE colonization can serve as a reservoir for the spread of these microorganisms to others, and can lead to infection in the host. Colonized patients are also known as asymptomatic carriers.

Infection is the entry and multiplication of microorganisms in the tissues of the host leading to local or systemic signs and symptoms of infection.
