Q

Name the 3 criteria for eradication of the AGENT/MICROORGANISM:

A
  1. Lack of an animal reservoir; only reservoir is a human host
  2. Only one causative agent or stereotype

A

Acute Flaccid Myelitis

18
Q

Name the 6 links of Smith’s Chain of Infection:

A
  1. Infectious Agent
  2. Reservoirs
  3. Portals of Exit
  4. Mode of transmission
  5. Portals of Entry
  6. Hosts
19
Q

This link in Smith’s Chain of Infection can be a bacteria, fungi, virus, protozoa, or rickettsia.

A

Infectious Agent

20
Q

This link in Smith’s Chain of Infection is a place where organisms live or hibernate but do not cause disease. The most common examples are humans, animals, or the environment such as soil or water. In healthcare, this can be on medical equipment.

A

Reservoirs

21
Q

This link in Smith’s Chain of Infection is the agent’s mechanism to leave its reservoir. Common examples in humans include excretions, secretions, and blood. For C. Botulinum spores, this is through food grown in the soil.

A

Portal of Exit

22
Q

**This link in Smith’s Chain of Infection includes examples such as direct person to person contact, indirect transmission through exposure to a contaminated vehicle or inanimate object, or through the air. This link can be broken through the use of hand hygiene, PPE, and appropriate cleaning/disinfection.

A

Modes of Transmission

23
Q

This link in Smith’s Chain of Infection include examples such as eyes, nose, mouth, genitalia, and broken skin.

A

Portal of Entry

24
Q

This is the last link in Smith’s Chain of Infection and certain populations are at higher risk of developing infectious disease d/t immunosuppression, age, nutrition, medications, chronic diseases and lack of natural or heard immunity.

A

Host

25
Q

In 1996, this system was established for the purpose of monitoring trends in the prevalence of ABX resistance among bacteria isolated from humans, retail meats, and food animals; disseminating public health info on abx resistance; promoting interventions that reduce resistance among enteric bacteria; and forming the approval process for the use of abx agents in veterinary medicine.

A

National Antimicrobial Resistance Monitoring System (NARMS)

26
Q

Name the 5 ways in which antibiotics are misused in humans

A
  1. Given when they are not needed
  2. Continued when they are no longer necessary
  3. Given at the wrong dose
  4. Broad spectrum agents are used to treat very susceptible bacteria
  5. The wrong abx is given to treat an infection
27
Q

Vancomycin resistant enterococci (VRE) was caused by antibiotics being used in this way:

A

Using certain antibiotics in animal feed

28
Q

An example of overuse of abx in the animal population can be seen with the use of ______ in poultry leading to increased resistance in animals and then humans to this class of drugs among human Campylobacter isolates. This led to the FDA withdrawing approval for the use of these drugs in poultry.

A

Fluroquinolones

29
Q

The Obama administration released a ________ to combat abx-resistant bacteria in 2015.

A

National Action Plan

30
Q

The CDC has instituted the ____ program to improve the awareness and practice related to antibiotics and prescribing practices.

A

“Get Smart” program

31
Q

The first step of the culturing process and provides important information for clinicians or epidemiologists, which can help identify potential causative agents r/t an outbreak exposure or for early treatment.

A

Gram staining

32
Q

_____ is the KEY because treatment options are limited and the mortality can be high.

A

PREVENTING the spread of bacterial agents

33
Q

These gram-negative organisms are resistant to ALL current antibiotics and allows a resistant gene to transfer easily from one cell to another. The mortality rate is very high (as much as 80%) w/no abx tx available.

A

Carbapenem-resistant Enterobacteriacease (CREs)
