When H. pylori was first discovered, researchers doubted the finding. It was thought that the acidic environment of the stomach was too hostile for microbes to thrive. Newer research using genetic analysis and culture techniques has revealed that there is a diverse gastric microbiota. Of the options below, what is the only one that does not involve genetic analyses?
A. Sequencing approaches have shown that the normal microbiota includes Archaea and provide mechanisms for studying their distribution.
B. Knowledge of growth rates allows researchers to predict responses to changing conditions.
C. Knowledge of the microbiota from sequencing efforts has been used to improve cultivation techniques.
D. Genetic analyses have been used to examine the dominant species in different individuals, showing that it varies from one individual to another.
