Based on Coco's follow-up urinalysis results and the fact that she is doing well at home, you recommend continuing treatment for another two weeks and performing a recheck urinalysis and culture five to seven days after antibiotic therapy.
At Coco's next visit, her owners report that she is doing well but still has intermittent episodes of urinating in the house. Her desire to go out all of the time has decreased.
Here are her follow-up test results:
Urine specific gravity
Given that Coco is still showing some clinical signs and that she has pyuria and proteinuria, you are still suspicious of an infection so you recommend a repeat urine bacterial culture. Fortunately, the clients agree. Note: Don't be misled by the absence of bacteriuria as this is not a sensitive indicator of infection, especially in a dilute urine sample.
Here are the urine bacterial culture and sensitivity testing results:
Organism: Pseudomonas species 10,000–50,000 cfu/ml
NA = not applicable
S = susceptible, R= resistant, I = intermediate
What could be the reason that Coco's urine bacterial culture is still positive? (There is more than one correct response.)
