Gram Negative Bacilli
A 55-year-old woman is noted to have pyelonephritis with shaking chills and fever. Blood cultures are obtained, and the Gram stain is read preliminarily as consistent with Proteus species. Which of the following bacteria also may be the etiology? (AIPG 2009)
|B||Group B Streptococcus|
Both proteus and E. coli are gram-negative rod bacilli.
E. coli is the most common isolate in UTIs. Gram stain in case of other options will show gram positive cocci.
