"...iron deficiency anemia caused by the xpili bacteria..."

Can you please clarify this statement? 'pili' is a common term - "Fimbriae and pili are thin, protein tubes originating from the cytoplasmic membrane of many bacteria {https://bio.libretexts.org/Bookshelves/Microbiology/Microbiology_(Kaiser)/Unit_1%3A_Introduction_to_Microbiology_and_Prokaryotic_Cell_Anatomy/2%3A_The_Prokaryotic_Cell_-_Bacteria/2.5%3A_Structures_Outside_the_Cell_Wall/2.5C%3A_Fimbriae_and_Pili}

I am not finding a specific 'xpili bacteria'; that would seem to indicate any bacteria that did not have pili protein projections.

As to Flagyl {metronidazole}, I took it some years ago and got rid of an ulcer; __it also got rid of a decades long painful rosacea__. I am still free of the rosacea many years later. I cannot point to any deleterious side effects to the Flagyl. It is specifically indicated in treatment of h-pylori bacteria that cause ulcers. I have since pushed Flagyl in treatment of rosacea. corsair9
