In this case study, we initially were presented with a case where a 2-year-old male child who had not had any immunisations. He experienced an upper respiratory tract infection experiencing anorexia and lethargy. This progressed into having a high temperature at 39.9 and physical symptoms including exudative pharyngitis and enlarged lymph nodes. He was given penicillin which did not improve the situation. His condition continued to decline with increase lethargy and respiratory distress, also presenting with a high temperature of 38.9 and had exudate on the pharynx what was of a yellowish thick membrane. This was 
scraped, removed and analysed through gram staining as well as being grown on cystine- tellurite blood agar.
