As previously stated, they appear as exceptionally tiny, poorly staining, gram-negative coccobacilli
Gram stain--Gram negative coccobacilli
, modified cold ZN stain--acid fast coccobacilli
, oxidase positive, catalase--positive, motility--non-motile, urease test--positive.
Psychrobacter species are nonmotile, nonpigmented, aerobic, gram-negative coccobacilli
, although Gram staining results are often variable (7).
The periorbital skin of the bird initially presented, contained large numbers of septate fungal hyphae in the dermis, as well as multifocal colonies of coccobacilli
Members of genus Acinetobacter are Gram-negative, non-motile, non-spore forming encapsulated coccobacilli
belonging to family Neisseriaceae.
Direct Gram stains from clinical specimens will reveal very small Gram-negative coccobacilli
, usually appearing as single cells.
On all media, the placental swab sample yielded moderate growth of tiny colonies, which Gram staining indicated were gram-positive coccobacilli
In several birds within the macrophages, there were vacuoles that contained basophilic small coccobacilli
organisms that were about 0.
Nonfermenting Gram-negative bacilli or coccobacilli
that were oxidase negative and nonmotile were presumptively identified as belonging to Genus Acinetobacter (2).
The presumptive interpretation of a microorganism is more useful than a description of the morphology, such as Gram-negative pleomorphic coccobacilli
Examination of smears originating from the positive blood cultures revealed bacteria that presented as pleomorphic, faintly staining, gram-negative coccobacilli
The patient was discharged from the ER on the same day, but was asked to return on April 6 after the blood cultures were reported positive for tiny, faintly staining, gram-negative coccobacilli
