colonic
95-99% anaerobes (esp. bacteroides, clostridial)
always present bacteroides fragillis bacteroids melanginogenicus E.coli ( most common cause of UTI) enterococcus faecalis (2nd most common UTI)
gram negative enteric bacilli can be present
- klebsiella
- salmonella
- shigella
- campylobacter
prophylactic drugs before ‘dirty surgery’ need to cover + examples
anaerobes
gram -ve bacilli
