Pathogens and Environmental Management Flashcards
pathogen
a disease causing agent
reservoir
where a pathogen may live, grow and reproduce
carrier
living organisms that harbor a potential pathogen
latent carrier
shed disease in a cyclic manner
fomite
inanimate objects that can carry and transmit disease
transmissibility
the potential or ability for a disease to spread from an infected carrier to a susceptible animal
disinfection
the killing, inhibition, or removal or microorganisms that may cause disease
-treatment of inanimate objects with chemicals
sanitization
reduction of the microbial population on an inanimate object to levels judge safe by public health standards
sterilization
the process by which all living cells, viable, spores, and viruses are either destroyed or removed from an object
static
to halt/ slow microorganism growth
cidal
to kill the microorganism
Autoclave
-121 C at 15 pounds of pressure
-destroys all vegetative cells and endorsors in 10-12 minutes
Sterilizing Gases
-used for heat sensitive materials (plastics, electronics, etc.)
-uses ethylene oxide gas
