The presence of gram-positive coccobacillary
forms, mostly organized in pairs, was confirmed for primary isolates.
Bordetella bronchiseptica is a Gram-negative coccobacillary
bacterium that causes respiratory tract disease in several mammalian species including kennel cough in dogs and snuffles in rabbits.
Rickettsiae are gram-negative coccobacillary
bacteria that are strict intracellular parasites.
Identification of gram-positive coccal and coccobacillary
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).
In a study on a limited number of patients with systemic sarcoidosis, acid-fast coccobacillary
forms were detected in biopsy materials.
