Organisms with fimbriae can be more pathogenic because it allows them to

Question 2
A voided urine culture from a 46-year-old female grows dark lactose fermenting as well as non-lactose fermenting colonies. The BAP shows gray, beta-hemolytic colonies under a swarming film of growth.
The microbiologist performs a spot indole test on swarming colony and it is positive. She reports the organism as presumptive Proteus vulgaris using the department's rapid identification criteria. The next day the second colony identifies as E. coli using a commercial identification system. Your next step in this process is to
A) report Proteus vulgaris and E. coli isolated.
B) repeat the identification of both organisms using a commercial identification system.
C) identify the non-lactose fermenting,, swarming colony using a commercial identification system.
D) question the identification of the E. coli colony and repeat testing.
