aureus - -Staphylococcus aureus is a type of
bacteria that is spherical, Gram-positive, and often
found on the skin or in the NOSE.
-It can cause skin and soft tissue infections, as well
as more serious infections such as pneumonia,
heart valve infections, and bone infections.
-It may be resistant to some antibiotics.
-not a problem when kept under control by a
protease found in S. epidermidis, but if left to
grow out of control, S. aureus CAN BECOME
PATHOGENIC.
Candida albicans - -fungus can cause oral infection
known as thrush (& in urogenital tract can cause
yeast infections)
Lactobacillus - -causes low pH in vagina and it
secretes lactic acid and hydrogen peroxide.
,-keeps other species in small numbers in the
vagina and its decrease due to antibiotic
disturbances
Bacteroidetes - -gram negative, anaerobic bacteria,
often found in intestinal tracts of animals and aid
in digestion.
-Fecal transplants help restore Bacteroidetes
-diets high in animal protein and fats have high
levels of Bacteroidetes
Clostridium difficile - -major cause of antibiotic
induced colitis & diarrhea.
-many strains are antibiotic resistant
-releases toxin as it grows that attack lining of the
intestines.
Helicobacter pylori - -bacteria has a helical shape
and colonizes the stomach and upper G.I. tract.
- It is known to be a major cause of stomach
ulcers, although many people with H. pylori do not
get ulcers.
-these bacteria may also be beneficial to the host,
as is the case for reducing the risk of obesity,
childhood asthma, inflammatory bowel disease
and celiac disease among others.
, Microsporum - fungi that feast on keratin in the
skin and cause "ringworm" fungal infections
-infects hair and skin
Trichophyton - fungi that feast on keratin in the
skin and cause 'ringworm' fungal infections.
-infects hair, skin, and nails
Microbe - tiny living organism, such as bacterium,
archaean, fungus, protist, or virus
Microbiome - collectively all the microbes in the
human body (i.e., a community of microbes)
Biofilm - a community of microbes that live
together on a surface
What types of cells are found in and on a typical,
healthy human body?
A.Viral cells
B.Fungal cells
C.Bacterial cells
D.Archaebacterial cells
E.Protists
F.All of the above - F.All of the above
