Corynebacterium diphtheriae, also called the pseudodiphtheria bacillus, is a genus of gram-positive cocci found in dried smears from pleural fluid, cardiac cavities, abdominal cavity, paranasal sinuses, sputum, urine sediment, feces, pus, or from the dry mass of cadaveric tissue. causative agent of diphtheria. Cocci can be single-layered, dumbbell-shaped, sessile, or spherical. Rarely does a chain or tight clusters form. The morphology of this genus depends on the type and phase of development of the bacterium. Cell sizes ranging from two to ten micrometers (µm) in diameter may be present. The upper surface of the protea has a rough texture. Among the known species we can distinguish c. pseudoruminatorum and s. diphtheria, which accordingly differ only in minor morphological features. Thus, the pseudodiphtheria bacillus can be confused with the causative agent of diphtheria, which indicates the significant similarity of these organisms in structure.
The information is quite scant. The exact source and time of infection is unknown. Bacterial nature is assumed. In humans, the disease manifests itself as oropharyngeal diphtheria. Due to the difficulties and costs of
