Phlebotomy 3 Flashcards
microorganism that invades the body, multiplies, and caused injury & disease
microbe
causing or capable of causing disease
pathogenic
pathogenic microbe
pathogen
nonpathogenic microbes on the skin and in the GI tract
normal flora
charged with investigation and control of various disease, especially those that are communicable and have epidemic potential
Centers for Disease Control & Prevention (CDC)
patient infections acquired in hospitals
nosocomial infection
infections acquired during healthcare delivery in all healthcare settings
Healthcare-associated infection (HAI)
intestinal bacteria that multiplies with antibiotic treatments and the most common cause of diarrhea in healthcare settings
Clostridium difficile (C. difficile, C. diff)
responsible for many HAIs from skin, wound, and surgical site infections, to pneumonia and bloodstream infections that can be fatal; also most common antibiotic resistant pathogen
methicillin-resistant staphylococcus (staph) aureus (MRSA)
antibiotic resistant bacteria that can cause bloodstream infections, wound, and surgical site infections
vancomycin-resistant enterococcus (VRE)
chain must be completed for infection to occur; the process can be stopped at any component; once the infection enters the host, the cycle repeats
chain of infection
pathogenic microbe responsible for causing infection
infectious agent
infectious agent
causative agent
source of infectious agent or place for microbe to survive, grow, and multiply
reservoir
ability of microbe to survive or live on an object
viability
degree to which the microbe is capable of causing disease and the amount of time passed since contamination
virulence
inanimate objects that can harbor material containing infectious agents
fomites
transfer of infection by insect, arthropod, or animal
vector transmission
