15
Q

what characteristics dictate microbe content

A

pH, oxygen, moisture, temp, nutrients

16
Q

what is aquatic MB

A

the study of microbes in freshwater and marine environments

17
Q

water ecosystems have more or less microbes than soil and why

A

less because the water dilutes the nutrients

18
Q

where do biofilms form (aquatic lly)

A

on the surface

19
Q

microbiome of humans def.

A

organisms that colonize the bodys surface without normally causing disease

20
Q

dysbiosis def

A

persistent imbalance in microbial community usuallly due to reduction in microbial diversity

21
Q

what is opportunistic pathogens refering to

A

normal microbiota that cause disease in certain circumstances
they usually move to and unusual site in the body and change the normal microbiota

22
Q

gut microbiome infor

A

can influence many systems in body

23
Q

dysbiosis in the gut could lead to what

A

stress, anxiety, heart issues, and so many other implications throughout the whole body

24
Q

where is the c. difficile disease happen

A

in the gut

25
Q

how to treat c. difficile

A

with FMT. a fecal microbiota transplant

26
Q

what does c.difficile do

A

limites many heatlhy gut species and causes dysbiosis

27
Q

what does FMT do

A

places donor fecal matter with high microbiome diversity into and individual with gut dysbiosis.

28
Q

before and after FMT

A

before there are many proteobacteria
after the proteobacteria are eliminated and microviridae are increased

29
Q

what organisms are abundant on the skin

A

different organisms are abundant in differey body locations

30
Q

what is candida auris

A

a fungal pathogen common in the healthcare environment

31
Q

what two states determine candida auris population

A

malassezia which prevents it and the candida species inhances it.
