Study Notes
Disinfection in Infection Control
- Disinfection plays a crucial role in infection control by reducing the number of microorganisms on surfaces, thereby preventing the spread of infection.
- The effectiveness of disinfection depends on various factors, including the type of disinfectant, concentration, contact time, and surface type.
Resistance to Disinfection
- Prions are highly resistant to disinfection, requiring specialized inactivation methods.
- Bacterial spores are also highly resistant to disinfection, while non-enveloped viruses are moderately resistant.
- Lipid-enveloped viruses, such as HIV, are relatively susceptible to disinfection.
Disinfectant Considerations
- When using disinfectants, factors such as concentration, contact time, and surface type should be considered to ensure effective disinfection.
- The importance of contact time lies in allowing the disinfectant to interact with the microorganism long enough to inactivate it.
Mechanism of Action and Potential Harm
- Disinfectants work by disrupting the cell membrane or inhibiting essential cellular processes, leading to the inactivation of microorganisms.
- Some disinfectants can be harmful to humans, animals, or the environment, so it is essential to handle them carefully and follow instructions.
Infection Control Plans
- An infection control plan should include strategies for prevention, detection, and response to outbreaks, as well as protocols for disinfection and sanitation.
Streptococcus Equi (S.equi)
- S.equi is a bacterium that can cause strangles in horses, and is highly susceptible to disinfection.
- An example application for S.equi is in equine veterinary medicine.
- Outbreaks of S.equi are often linked to contaminated water sources, and the bacteria can survive in water for up to 2 months.
- The carriage risk of S.equi typically occurs in the first 4-6 weeks after infection.
- Vaccination is an effective measure for preventing S.equi infection.
Salmonella
- The primary route of infection for Salmonella is through the fecal-oral route, often via contaminated food or water.
- Isolated animals should be kept separate from the rest of the population during infection control for Salmonella.
- Before disinfection, it is essential to remove organic material to reduce the effectiveness of the disinfectant.
Canine Parvovirus (CPV)
- One approach to managing CPV is through vaccination and proper sanitation and disinfection protocols.
General Infection Control
- Cleaning and disinfection are crucial components of infection control, and should be performed in a specific order to maximize effectiveness.
- Removing organic material before disinfection is essential to ensure the effectiveness of the disinfectant.
