normal flora of mouth
strep viridans, neisseria species, anaerobes, candida, staphylococci
normal flora of stomach duodenum
usually sterile small amount of candida and staphylococci
PPIS
increase risk of infection because they alter the normal pH of the stomach
normal flora of the jejunum
small amounts of coliforms and anaerobes
normal flora of the colon
large amount of coliforms, anaerobes and enterococcus faecalis
normal flora of the bile ducts
sterile
what are coliforms
gram negative large bacilli which is aerobic (E.coli, klebsieela, proteus, enterobacter, seratia)
sepsis caused by coliforms
gentamicin is the drug of choice to cover coliforms (aztreonam can be used if gentamicin is contra-indicated i.e. in severe renal failure where EGFR is less than 20), co-trimoxazole is given orally as the step down
strict anaerobes will
not grow in oxygen
what organisms are strict anaerobes
clostridium and bactericides
drug of choice for covering anaerobes
metronidazole
e.coli is
a gram negative aerobic bacilli which is lactose fermenting
pseudomonas aerguinosa is a
gram negative strict aerobic bacilli which is not lactose fermenting
drug of choice for covering enterococcus
amoxicillin, switch to co-trimoxazole when stepping down
opportunistic pathogens
are pathogens that cause infections in vulnerable hosts
example of an opportunistic pathogen
Pneumocystis jirovecci which causes pneumonia in people with HIV
