Suttonella indologenes\s a fastidious gram-negative coccobacillus
that is oxidase and indole positive and catalase negative and can ferment sucrose and glucose (2).
Most laboratories indicated some awareness of the isolate's identity, with only 13.6% (150 participants) indicating nonspecifically that the organism was a gram-negative coccobacillus
, aerobic; gram-negative coccobacillus
, not otherwise specified; or gram-negative bacillus, not otherwise specified.
Tularemia is caused by the gram-negative coccobacillus
Francisella tularensis, which is found in rodents, rabbits and hares.
Microscopic examination of respiratory secretions or blood using gram stain reveals a gram negative coccobacillus

I was not disappointed and gleaned an understanding and respect for the dangers surrounding this small aerobic, gram-negative coccobacillus
known as francisella tularensis.

We recovered bacterial counts (>[10.sup.5] CFU/mL) of an oxidase-positive gram-negative coccobacillus
producing small ([approximately equal to]1 mm) white colonies in pure culture.
Emerging data suggest that Trueperella bernardiae, a recently identified Gram-positive coccobacillus
, is the cause of infections associated with surgical procedures and in the setting of comorbid conditions, including diabetes mellitus.
multocida appeared as gram negative, non-motile, non-spore forming short rod or coccobacillus
