Survival: Microbe Clock
A) Describe in detail how Streptococcus pneumoniae has developed antibiotic resistance over the past century.
Streptococcus pneumonia has developed resistance over the past century by developing strains which have evolved resistance. Streptococcus has become completely resistant to penicillin and the search for alternative antibiotics has been unsucessful. Since the year 1997 Streptococcus has developed resistance to at stockpile of at least 100 drugs. The list of microbes that have developed resistance is growing quickly.
B) Start the clock. The one minute of division here represents 186 days of actual division. How many times did the cells divide in this time? How many total cells resulted at the end of this time? How many mutations occcurred in the population during this time?
The cells that divided were a total of 313,807, the total number of cells were 13,274, the total number of mutations that occurred were 1,314
