in the hair, in the presence of oil
What microorganisms can be found on the eye?
- staphylococcus epidermidis
2. found on conjunctiva from birth throughout life
What type of microflora can be found on the external ear?
- gram negative, gram positive organisms
- halophiles (salt loving)
- fungi
S. mutans and lactobacillus are exampls of what type of bacteria?
- oral bacteria that cause dental carries
What must organisms in the mouth be able to withstand in order to survive?
- withstand mechanical removal. (adhere to gums and teeth)
2. colonized in hours after birth
Where are staphylococcus aureus and staphylococcus epidermidis most likely to be found?
- predominant inside the nostrils
What organisms are most likely found in the pharynx and the trachea?
- Gram positive
- staphylococci
- micrococci
- diptheroids
- streptococci
Which region of the upper respiratory tract is most likely to contain low numbers of pathogenic microbes?
nasopharynx
What microbes are contained in the lower respiratory tract?
- none, sterile environment
2. microbes are moved via ciliary escalator up and out to the esophagus
What is the benefit of the stomach having such a low pH?
- kills majority of the microbes present
What are some unique characteristics of microbes that reside in the large intestine?
- eliminated via peristalsis, dequamation, and mucus movement
- rapid rate of replacement
- mostly anaerobes present
What exact bacteria are located in the large intestine?
- E. Coli
- bacteroides
- fusobacterium
- lactobacillus
- enterococcus
- bifidobacterium
- enterobacter
- citrobacter

- klebsiella
- candida
What microbes are present in the renal system?
- microbe free (sterile environment)
What microbes are present in the female genital tract?
- constant flux due to menstrual cycle
2. acid-tolerant lactobacilli
How do lactobacilli survive in the vaginal canal?
- produce hydrogen peroxide and glow on glycogen secretions present
- positive urine leukocyte test indicates infection present UTI

What is unique about the skin that protects against harmful microbes?

What helps to flush the large amount of microbes that can be found in the large intestine, out of the body?
- diarrhea
2. rapid shedding of the intestinal lining
