You are looking for a certain bacteria species in a person's microbiome. You know that if the species is present, it will make up a very tiny proportion of the overall microbiome. What should you change about your experiment to increase your chances of finding this species if it is present?

To increase the chance of finding this species, what is suggested is to increase the number of samples evaluated in the person's microbiome. On the one hand we can increase the sample size or the number of samples of the experiment. Another possibility is to take samples from different parts of the body.
