Modes of Transmission and Drug-Resistant Bacteria

Vocabulary flashcards covering chain of infection, modes of transmission, and drug-resistant bacteria including C. Diff and Vancomycin-resistant enterococci.

Chain of Infection

The cycle of infection consisting of six key elements: Infectious agent, Reservoir, Portal of exit, Mode of transmission, Portal of entry, and Susceptible host.

Modes of Transmission

The five identified routes for disease spread: 1. Contact, 2. Airborne, 3. Droplet, 4. Vehicle, and 5. Vector-borne.

Clostridium difficile (C. Diff) Clinical Manifestations

Clinical presentation ranging from mild watery diarrhea to fatal colon inflammation.

Clostridium difficile (C. Diff) Risk Factors

Risk factors including long-term care faculties, long-term antibiotic use, and being over 65.

Clostridium difficile (C. Diff) Transmission

Methods of transmission including fecal-oral route and tube feeding.

Vancomycin-resistant enterococci

A drug-resistant bacterium with location-specific clinical manifestations, transmitted via contact of surfaces and people.

Vancomycin-resistant enterococci Risk Factors

Risk factors including long-term antibiotic use, surgeries, and a suppressed immune system.
