I have a dataset that has abundance of different bacteria in different mice type. Let’s say mice are called: sw/c57, sw/sw, c57/c57 and c57/sw. The fecal samples of these mice have been analyzed and the number of present bacteria in their fecal samples is available. Now I want to find those bacteria that are significantly different in any of the mice type. E.g. Prevotela is significantly different in c57/c57 comparing to other mice.
An example of my dataset:
sw/sw sw/c57 c57/c57 c57/sw Roseburia 500 141 0 589 Prevotela 300 131 237 288
Each mice type has 10 replicates.
What kind of statistical test I should use to analyze my data?
