What is vaginal infections, giardia, and bacteria C difficile?

A vagina infection is a very broad term to describe any infection of the vagina (circular logic, I know, but let me explain). You can have a yeast infection in the vagina. You can have a parasitic infection of the vagina (like trichomoniasis). Or you could have a bacterial infection of the vagina like bacterial vaginosis (Gardnerella), chlamydia or gonorrhea.





Giardia is an enteric parasite. It's a protozoan you contract from drinking contaminated water. It is passed fecal-orally. Dogs can get giardiasis and pass it to humans through their waste. Giardiasis can last several months if untreated and usually presents with periodic spells of gaseous bloating, flatulence, diarrhea, light-colored greasy stools and no fevers. It is curable with Flagyl (metronidazole).





C. difficile is Clostridium difficile. It can cause severe diarrhea. When the bacteria proliferate, they release large amounts of a toxin that triggers the diarrhea. This bacteria is "difficile" because it comes as a side effect of antibiotic use in some patients (usually the weak or elderly) and can be hard to get rid of.
