Bacillus; Aerobic + Clostridium; Anaerobic.
Non-Spore Forming Rods: (most bacteria do not make spores)
Listeria Monocytogenes and Corynebacterium Diptheriae
- Non-spore forming but aerobic.
- Psychrophile: can multiply in low temperatures.
- Common in the air or soil; small number can be tolerated
- Found in soft cheese, unpasteurized, milk, cold cuts, Pate.
- The symptoms are mild;
- The elderly are at risk; very few organisms that can gross the placenta and infect the fetus
- Immunocompromised are at high risk.
- Causes diphtheria. The exotoxin causes the damage.
- Damage the heart circulatory system and neural cells; CNS.
- Not common; now found in a vaccine that we get.
- Nasty pathogen. In non-developed remote.
Gram Negative Bacilli:
They affect the enteric system; referred to as ENTERICS; VOMIT, DIARHEA; CRAMPS
- Enterics; have different groupings;
- Differential Media; Maconkey Media (pink-purple) EMB Media; has both inhibiting substances
to differentiate the ingredients; (dark purple.)
- We need many tests to differentiate these bacteria; hydrolysis of area; immunity test against its
pili, flagella, capsule.
- You can test them on their antigenic structure.
- 1.) They can cause diarrhea and not much other damage.
- 2.) They can penetrate in the guy lining and cause cell damage.
- 3.) They can penetrate into the bloodstream and cause nasty infections
- Normal flora; can escape and cause infections.
- Most common gram-negative bacilli.
- Non lactose fermenter lactose
- Most common host; Animal Source.
- Mild and mostly diarrhea like symptoms. Can get to other parts of the body.
- 2 types that we need to worry about; Enteritidis
