-
Lactobacillus species
- beer production
- commonly found in arsenic soils
-
L. delbruekii
- high acid producers
- lining of vagina
-
Actinoyces bovis
found on mucous membranes; opportunistic
- breaks down small molecules on surface of skin
- if you're immunocompromised, it can cause scepsis or renal failure or pneumonia
-
C. diphtheriae
- diphtheria (bullneck)
- when patient has bullneck, it can be one of these:
- mumps can cause this
- benign head/ neck tumors
- obesity
- diphtheria: toxin is on a virus; phage contains toxin (potent)
- gets double knock out
- -> lymphdema: not enough air flow due to mechanical problem--> can get pneumonia on top
behind the grey pseudomembrane, all the tissue is dead; it can kill any tissues
-
Mycobacterium tuberculosis
causes tuberculosis
- in general, mammalian immune system does a bad job dealing with it
- has strains that are resistant
remodeling in lungs that form a structre in lung called the ghon complex that has bacteria and immune cells
- --> if cure, that's enough to keep you alive
- --> if freq. infected, the ghon complex bursts
-
Ghon clompex cont.
--after bursting
if in lungs, reinfection of the bacteria and formation of ghon complex, which prevents respiration from occurring
if into pleural cavity: systemic tuberculosis--> migrates and finds new territory (liver, kidney, colon)--> miliary tuberculosis------>
liver: immune system can't do anything--> ghon complexes--> metabolic and physical function not occurring
-
Mycobacterium leprae
leprosy
body can't deal well with bacterium; tissue remodeling in cartilage
ghon like nodules--> can be in joints and deforms joints
large shallow open sores; hypoxia below; loss of normal architecture
secondary infection over feelt and hands where open sores are located
not a lot of damage to elbow and knee
-
Nocardia asteroides
pulmonary Nocardiosis in compromised patients
very rapid onset
