In Gram's staining pink, gram negative, coccobacillary
rods (Fig 2).
Canine monocytic Ehrlichiosis is caused by Ehrlichia canis, a gram negative coccobacillary
bacteria of family Anaplasmataceae.
In Gram stain of direct smears Acinetobacter appeared as tiny, Gram-negative coccobacillary
cells often appearing as diplococci.
53) Histology reveals the typical granulation tissuelike appearance of the lesions (Figure 3, c), with scattered nuclear debris and aggregates of extracellular amphophilic granular bacterial deposits, which demonstrate a coccobacillary
morphology on a Warthin-Starry stain (Figure 3, d).
