Discussion After doing a series of different biochemical tests for the isolated organisim from the sputum sample‚ it was concluded that the unknown Gram positive organism was Streptococcus pyogenes. The sputum sample was first inoculated in the agar plates MAC‚ SBAP‚ CHOC and also a direct gram stain of the sample was performed. After a day of incubation‚ the MAC agar gave a negative result‚ therefore it is not a Gram-negative bacteria and non-lactose fermenting. The SBAP and CHOC showed growth
