All are true about given bacteria except:
Above staining shows cuneiform arrangement/ chinese letter pattern of C. diphtheriae. C. diphtheriae- Gram-positive, highly pleomorphic organisms with paicular arrangement. Special stains like Neisser and Ponder's stain are used to demonstrate the metachromatic granules It is sensitive to the majority of antibiotics, such as the penicillins, ampicillin, cephalosporins etc. Upper respiratory system involvement is early presentation Complication: The exotoxin of C. diptheriae is absorbed in the blood which in turn kills hea, kidney, and nerve cells by blocking protein synthesis.
Gram-positive, highly pleomorphic organisms with paicular arrangement.
Cardiovascular system involvement is early presentation
Special stains are Neisser and Ponder's stain
It is sensitive to the majority of antibiotics, such as the penicillins, ampicillin, cephalosporins etc.
