G+ cocci
5-15% harbos as normal flora in respiratory tract

-->spread thru droplet or direct contact

-necrotizing fasciitis
can lead to sepsis and death of left untreated

6

Clostridium botulinum

Gram + rod
spore forming
found in soil/water
-->food born illness from improper canning/presserving methods

toxins released colonize in GI tract,
disease= flaccid paralysis

7

clostridium difficile
c. diff

G+ rod
normal flora of stomach
spore forming

nosocomial

-antibiotic associated diarrhea
normal gut flora wiped out by antibiotics causes C. diff to overgrow
-inflammation of the colon, colitis

8

clostridium perfringes

Gram+ rod
dust/dirt/ nature, decaying vegetation
spore forming

-gang grene (in diabetics)
-tissue nicrosis

9

Clostridium tetani

G+ rod in fresh cultures (g- in established)??
found in soil (manure treated) & GI tract of animals
spore forming
vaccine

-->enters host thru wound on skin
-tetanus - muscle spasms, respiratory failyre, death

10

Corynebacterium diphtheriae

G+
vaccine
___ dust/closing/blood/skin

-->direct physical contact breathing air secretion of infected ppl
-diptheria: low fever, chills, fatigue, sore throat, pain swallowing, breathing problems, bloodstained/foul smelling nasal discharch , adherent membrane on tonsils/pharync

11

listeria monocytongenes

G+ rod
soil/fecal matter
normal flora of 10% human GI tracts

pasteurized dairy products, raw milk, cheese, meat, fish - can grow in refrigerator

-->food born illness - leading cause of death related to food-born illness
-listeriosis: septicemia, meningitis, encephalitis

-pregnant mothers/meningitis in new borns

12

Neisseria gonorrhoeae

G- cocci
found in human body

-gonorrhea- sexually transmitted
-->contact with infected person
silver nitrate drops in babies eyes to protect

many people are asymptomatic

13

Neisseria meningitides

G- cocci
normal flora of nasopharynx

opportunistic
direct contact

-most common source of bacterial meningitis
only known strain to cause epidemic

e. coli

G- rod
normal flora of lower intestine
opportunistic
-->fecal-oral transmission

-UTI
-Gastroenteritis (stomach flu)

17

Haemophilus influenza

G- rod
normal flora of upper respiratory tract
-->close contact, airborn

-meningitis, acute respiratory infections (children especially)
-pneumonia

18

helicobacter pylori

G- rod
nomral flora of stomach/duodenum

-ulcers
-stomach cancer

19

klebsiella pneumonia

G- rod
normal flora of intestines, skin, mouth,
nosocomial, opportunistic

amoebae in natural environment
-->breath in mist/vapor (not person to person) immunosuppressed
many species

legionnaires disease
-pneumonia
-flu-like, cough, GI, nervous system, diarrhea nausea

21

Pseudomonas aeruginosa

G- rod
water, soil, skin flora
opportunistic/nosocomial
immunosuppressed (AIDS, diabetes, CF, burn victims)

-infections in open wounds,/ burn victims lead to blood infections
