Publication Date: February 2007
Slide 1. Escherichia coli
This Gram stain shows neutrophils and numerous plump, gram-negative bacilli that vary little in size or shape.
Proteus mirabilis (Enlarged view)
Slide 2. Proteus mirabilis
These short to medium-long gram-negative bacilli look like typical enteric gram-negative bacteria; isolation of Proteus mirabilis confirmed that impression.
Citrobacter diversus (Enlarged view)
Slide 3. Citrobacter diversus
These short, slender gram-negative bacilli look like enteric bacteria. The culture grew Citrobacter diversus.
Acinetobacter baumanii (Enlarged view)
Slide 4. Acinetobacter baumanii
Some of the short, fat, pleomorphic gram-negative bacilli resemble cocci, others diplococci. The variety of shapes is typical of this organism, which can be confused with Neisseria species.
