Salmonella	Undercooked fowl, raw egg	Fever, stark diarrhea, tum cramps
Escherichia coli (E. coli)	Contaminated water, unpasteurized milk	UTIs, hard digestive hurt
Campylobacter	Poultry, unpasteurised dairy	Diarrhea, pyrexia, cramp

Unintentional Ingestion and Sexual Transmission

The bacteria point mucous membrane institute in the genital, rectal, and unwritten pit. Because these region are naturally warm and moist, they provide an idealistic brooder for these pathogen to establish an infection.

Cardiovascular and Joint Pathways

While rare, bacteria can sometimes short-circuit the traditional barriers and enter the bloodstream or joints forthwith. This usually happens due to specific medical procedures. For instance, invading devices like catheters or artificial join can present bacteria directly into the aseptic environment of the profligate. Yet minor dental work, like a root duct or tooth descent, can send bacteria from the mouth into the bloodstream.
