The granular, wrinkled, yellow/white-pigmented colonies shown in the photograph were recovered on chocolate agar after 48 hours of incubation from a respiratory specimen collected from a patient with cystic fibrosis. Note in the lower composite photograph that colonies on the surface of blood agar are flat, granular, and only slightly wrinkled. On MacConkey agar the colonies lack lactose fermentation and lack pyocyanin production. The spot oxidase test is positive, and nitrates are reduced. With these observations, select the presumptive identification of this isolate. The answer is in the morphology.  

The bacterial species growing on the surface of the MacConkey agar plate shown in this photograph, a coccobacillary non-fermenter and a common cause of nosocomial hospital-acquired pneumonia, can be presumptively identified as:

Pseudomonas aeruginosa produces pyocyanin (bright bluish pigment on Mueller-Hinton agar)?

Identify a few attributes for each the following types of investments: stocks, bonds, preferred stocks, and mutual funds/ETFs (which may be stock funds, bond funds, or hybrid funds). Why might an investor select each type (consider mutual funds/ETFs as one type of investment in your answer)?

What is the role of a sentinel laboratory within the Laboratory Response Network (LRN)?
