Lab #12 Disease Transmission--Hand washing activity and epidemic stimulation

What does this phrase mean "microorganisms are ubiquitous"

It means they are everywhere

True or false most of organisms we encounter in everyday life are not pathogenic and can be extremely beneficial to our health.

True

why did number not double during epidemic stimulation

because infected people were already interacting with infected people at that time

purpose of epidemic stimulation

demonstrate how quickly an infection or pathogen can spread between humans resulting an epidemic epidemic=wide spread at specific time

epidemic vs pandemic

epidemic=wide spread at a specific time pandemic=worldwide spread

nosocomial infection

infection acquired in a hospital stay

fomites

inmate objects, one of the most important means of disease transmission

type of microbes present on hands after washed with soap and water for 20 secs?

normal microbiota

who are more susceptible to infections in hospital?

patients who are immunocompromised by disease or trauma

pH indicator for epidemic stimulation

phenol red positive=yellow negative=red

what type of microbes are likely to be present on unwashed hands? washed hands?

unwashed hands=microbes picked up from touching inanimate objects washed hands= normal microbiota

how do microbes spread

via hands or fomites

how do pathogens spread between among patients in hospital

when nurses doctors or health professionals fail to wash their hands properly while sterilizing instruments or examining patients
