microbiome/medically important bacteria/ medically important protozoans Flashcards
what is a symbiotic relationship?
where different species live closely together and they can be beneficial, neutral, harmful
define mutualism
both species benefit
define commensalism
one is benefitted the other is not affected
define parasitism
one species, the parasite is the only one to benefit
define dysbiosis
imbalance of natural microorganisms like bacteria, fungi, viruses that live in the gut for example
define an opportunistic infection
microorganism like bacteria, fungi, and viruses taking advantage of a weak immune system
novel pathogens
an unfamiliar type of pathogen that is hard to control, and example- covid
what are ways bacteria is helpful medically?
digestion
production of medicine
research study
fermentation
biotechnology
how does bacteria help digestion?
food is broken down and nutrients good for health are processed
how does bacteria help production of medicine?
production of various medicines, antibiotics, insulin, vaccines
how does bacteria help fermentation?
bacteria used to ferment food like yogurt and cheese
how is bacteria used in biotechnology?
genetic engineering, protein production
what does mechanism of pathogenicity mean?
ways in which a microorganism like bacteria or virus causes disease
how is attachment used as a mechanism of pathogenicity?
specialized structures of proteins that allow them to attach to specific cells or tissues
how is invasion used as a mechanism of pathogenicity?
pathogens can penetrate host cells or tissues by secreting barrier breaking enzymes or exploiting host cell processes
