Quiz 7 Bacteria Cont
Gurnick Quiz 7 Bacteria Continued
Question | Answer |
---|---|
Normal flora | the good bacteria that lives on the surface of the body |
Where flora lives for humans | in the resp. system the GI track and the urinary track |
How does flora protect us | creates competition for bad bacteria |
what flora is produced in large intestine | vitamin K and Biotin |
vitamin k | coenzyme for clotting factors |
biotin | coenzyme necessary for normal metabolism |
vitamin k factoid | babies are born with a sterile gut and no source of vitamin k they are injected with vitamin k within first 15 mins of life |
we have a symbiotic relationship with bacteria | live in harmony- they do good things for us we give them food and shelter |
what is the opposite of a symbiotic relationship | host/parasite survives at the expense of the host without benififiting the host |
pathogen | when a parasite creates harm or a disease |
pathogenic microbes | germs |
pathogens | always cause problems when presented in ample amounts, there is a min. number required to cause disease |
opportunisitic germs or pathogens | a. usually not harmful b. growth controlled by immune system c. normally present as flora |
secondary bacterial infection | occurs when immune system down, like if you have the flu and dont take care of it, bacteria will go rampant |
what affects the incidence of opportunistic bacteria? | a. viral flu b. excessive stress/cortisol c. taking immuno-suppresant |
Abx | Anti-biotics |
Do antibiotics kill viruses? | NO |
Do antibiotics kill bacteria? | YES |
What are some of the side affects of taking antibiotics? | inactivates oral birth control, disturbs flora in the gut |
what are the two ways bacteria causes illness | infection or intoxication |
food born infections | caused by ingesting live bacteria |
incubation of infection | 1-3 weeks |
intoxication | ingest toxins from bacteria that poison host, only certain species of bacteria produce toxin |
Example of intoxication | Botulism (botox) causes paralysis |
who is most suceptible to lower immunity | kids under age of 2 elderly preggo immuno-suppresants |
Compromised immunity can cause | dehydration and renal failure |
Species E. Coli | Eschenchia Coli opportunistic |
E. Coli | food born infection, contamination from animal feces causes diarreah |
Staph or Staphlycoccus | opportunistic, part of skin flora, produces gut toxins, no taste or smell |
Staph | can cause skin acne, food poisoning in gut, onset 4-6 hours, causes nausea, vomitting and diarreah |
Bacillus Cerrus | comes from spores (grain, fruit, veg) |
Bacillus Cerrus | causes food born infection, nausea and vomitting only |
H. Pylori | Helicobacteria Pylon |
H. Pylori | opportunistic, lives in gut, 90% people have it |
H. Pylori | can cause peptic ulcer, strips protective mucus of stomach wall stress, smoking, drinking, caffiene and blood type O makes worse |
PUD | peptic ulcer disease |
MRSA | Methycillin Resistant Staph Aurelos |
MRSA | resistant to penicillin, only responds to IV antibiotics |
MRSA aka Nosocomial infection | acquired in hospital by the patient |
MRSA | causes infections (wounds/bed sores) |
What causes MRSA to be penicillin resistance | due to the production of the enzyme B-lactominase, deactivates penicillin |
Could this be ANY more boring | NO |
