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
