Explain the growth curve of S. pneumo ?..

Answer / Gaurav Krishan

The growth curve of Streptococcus pneumoniae (S. pneumo) exhibits a logarithmic growth phase, lag phase, exponential growth phase, stationary phase, and decline phase. During the logarithmic phase, bacterial numbers increase exponentially over time. The exponential growth phase follows, where the growth rate slows but remains steady. The stationary phase occurs when the population is no longer growing due to depletion of nutrients or accumulation of toxic waste products. Finally, the decline phase occurs as a result of cell lysis or death.
