bacilofobia 3
If bacteriophobia exists, I don't know if this word has any reason to exist, because it is also the fear of germs that produce diseases but using a Latin word such as baculus, i ("rod" [because of the shape of some germs]) instead of the Greek bacteria (also "rod") which would be more appropriate for a phobia. Although in microbiology there are differences between bacteria with the genus Bacillus and its class Bacilli, in the case of phobia it is exactly the same.
