Exam 2
Multidrug-Resistant Organism Infectious Disorders:
What is required for a pathogen to cause a disease?
A susceptible host and a mode of transmission
Multidrug-Resistant Organism Infectious Disorders:
What is required for an infection to be transmitted?
A transport mechanism
Multidrug-Resistant Organism Infectious Disorders:
What are modes of transmission?
Routes of transmission:

MULTIDRUG-RESISTANT ORGANISMS :
Epidemiology of:
Vancomycin-resistant enterococci
3rd most common organisms seen in nosocomial infections
MULTIDRUG-RESISTANT ORGANISMS :
Pathophysiology of Vancomycin-resistant enterococci
Remain viable on environmental surfaces for 7 days to 2 months
MULTIDRUG-RESISTANT ORGANISMS:
Clinical Manifestations of Vancomycin-resistant enterococci (VRE):
Back pain, pain on urination, sensation of needing to urinate, and fever
Wound infections typically present as red and hot
MULTIDRUG-RESISTANT ORGANISMS:
Complications of Vancomycin-resistant enterococci
Growing list of resistance to antimicrobial agents
Emergence of vancomycin-resistant S aureus
MULTIDRUG-RESISTANT ORGANISMS:
Epidemiology of C. Diff
Most common cause of antibiotic-associated diarrhea in the U.S.
MULTIDRUG-RESISTANT ORGANISMS:
Pathophysiology of C. Diff
Spore-forming, gram-positive anaerobic bacillus
Transmitted through the oral fecal route
MULTIDRUG-RESISTANT ORGANISMS:
C. Diff
3 ways patients exposed in hospitals
Contact with health-care workers’ contaminated hands
Contact with the contaminated environment
Direct contact with a patient with a C diff infection
