Microbe minutes exam 3 Flashcards
large spherical bacteria
DR
single rods
LM /PA
rods and chains of varying length
LA
long straight rods
mt
Naturally found in the human GI tract, lining mouth, and normal vaginal flora• Naturally found in the human GI tract, lining mouth, and normal vaginal flora
LA
unusual cell wall rich in lipids
impervious to gram stain
MT
Found in raw milk, cheeses, icecream, raw vegetables, processed meats
LM/LA
Habitat is areas rich in organic material, such as soil, feces, meat , sewage, dried foods, and room dust
DR
• Family pseudomonadaceae
PA
• Four cells stick together, forming tetrad
DR
• trated with penicillin or amplicillin
LM
• Grows in acid environment prefers pH below 5
LA
• Unbiquitous: soil, water, skin
PA
• responsible for tuberculosis, disease which involves infection in lungs of mammals, eventually forming tubercules or small nodules and lesions
MT
• Can help those who are lactose intoleratnt
LA
o MDR TB: multi drug resistance to 2 drugs, isoniazid & rifampicin
o XDR TB: extremely drug resistant, resistant to multiple lines of drugs.
MT
• Grows in phagocytic cells and produces explosive polymerization of actin filaments
LM
• 3 stages of infection
o bacterial attachment and colonization
o local infection
o bloodstream dissemination and systematic disease
PA
• Multiple copies of its genome and rapid DNA repair mechanisms
DR
• Taken up by eukaryotic host cell by phagocytosis the escapes phagosome with enzymes
LM
• detoxifies the ionic mercury residue frequently found in radioactive waste generated from nuclear weapons manufacture.
DR
• Has ability to create lactic acid from fermenting lactose, normalizes digestion
LA
- accounts for 10% of all nosocomial infections: Pneumonia and urinary tract infections
- extremely high mortality rates in burn wound infections and pneumonia
- symptoms: fever, shock, neurologic deficit, jaundice, tachycardia, decreased range of motion
PA
- Transmitted through airborene particles, called droplet nuclei which are 1-5 microns in diameter.
- Macrophages in lungs are unable to digest the bacterium, live and reproduce within the macrophages themselves.
