what are some benefits of normal microbes?
competition among bacteria
- nutrients (produce substances harmful to the invading microbes "Ex: bacteriocins")
- affect pH
- oxygen availability
- fight off viral infection in the lungs
- brain development and immunity
upsetting the balance of normal microbes/normal flora can cause what?
- disease
- Ex: by taking antibiotics
opportunistic microbes
- sometimes if a microbe gets to another part of the body it may cause disease
- Ex: E. Coli - if it moves from the intestine to the urinary bladder, lungs, etc..
opportunistic pathogens
- normally don't cause disease in a healthy host but may cause disease in a sick person (Ex:
someone with AIDS)
- many people also carry around microbes which are pathogenic but do not carry disease
what is an example of a pathogenic microbe that many people carry?
1|Page
, streptococcus & pneumonia
(commonly lives in your throat and nose and can cause a type of pneumonia)
epidemic
many people in a given area acquires a disease in a short time
pandemic
an epidemic that occurs worldwide
what are the 2 different types of infection?
1) primary infection
2) secondary infection
primary infection
an acute infection that causes the initial illness
ex: the flu
secondary infection
caused by an opportunistic pathogen after the primary infection has weakened the body's
defenses
- ex: the flu can lead to a bacterial infection or AIDS leading to pneumonia
bacteremia
the presence of bacteria in the blood (if it multiplies in the blood it's called septicemia)
septicemia
blood poisoning from multiplication of pathogens
toxemia
toxins in the blood
(ex: tetanus)
viremia
presence of viruses in the blood
diseases in humans:
- AIDS
- diphtheria
