Susceptibility of porcine common diseases and disinfectants
The Susceptibility of Common Pig Diseases to Disinfectants
1. **Swine Fever (Classical Swine Fever):** This highly contagious viral disease is effectively controlled using alkaline disinfectants such as caustic soda (sodium hydroxide) and quicklime. In colder seasons, a 5% salt solution of sodium hydroxide is often recommended for better effectiveness.
2. **Foot-and-Mouth Disease (FMD):** FMD virus is sensitive to heat, acidic, and alkaline disinfectants. It can be inactivated by proper cleaning and disinfection procedures, especially when using agents like chlorine-based solutions or quaternary ammonium compounds.
3. **Blue Ear Disease (Porcine Reproductive and Respiratory Syndrome - PRRS):** The virus is more stable under neutral to slightly acidic conditions (pH 5–7), with high sensitivity to disinfectants. A kill rate of over 90% is typically achieved with appropriate treatments.
4. **Circovirus (Porcine Circovirus - PCV):** This virus is sensitive to iodine-based disinfectants but can survive for extended periods in acidic environments and chloroform. It is also resistant to some common disinfectants and can remain viable at 72°C for certain durations.
5. **Pseudorabies (Aujeszky's Disease):** The virus is sensitive to both acidic and alkaline conditions, as well as iodine-based disinfectants. Proper sanitation is crucial for prevention.
6. **Parvovirus:** This virus is highly susceptible to alkaline solutions and 0.5% bleach. Effective disinfection is essential to prevent outbreaks, especially in piglets.
7. **Japanese Encephalitis:** Most commonly used disinfectants, including double quaternary ammonium salts, are effective against this virus.
8. **Infectious Gastroenteritis:** The virus is sensitive to alkalis, quaternary ammonium salts, and povidone-iodine. These agents are widely used in swine farms for hygiene control.
9. **Rotavirus:** Rotaviruses are sensitive to chloroform and ether but not to most chemical disinfectants. Special care is needed during cleaning and disinfection.
10. **Influenza (Swine Flu):** The virus is sensitive to phenol and ether, but it is generally advised to avoid phenolic disinfectants when dealing with respiratory diseases due to potential irritation.
11. **Infectious Pleuropneumonia:** Benzalkonium bromide is an effective disinfectant for controlling this bacterial infection.
12. **Infectious Atrophic Rhinitis:** Benzopyrazole and iodine-based disinfectants are effective in reducing the spread of this condition.
13. **Asthma (in pigs, usually refers to respiratory issues):** Double quaternary ammonium salts and iodine are commonly used for disinfection in affected areas.
14. **Pulmonary Plague (not a common term, likely referring to bacterial pneumonia):** Sensitivity to pyrogenic alkaloids and benzalkonium bromide makes these agents useful for treatment and prevention.
15. **Streptococcus:** This bacterium is sensitive to benzalkonium bromide and 3% bleaching powder. Regular cleaning helps reduce its presence.
16. **Piglet Paratyphoid (Salmonellosis):** Sensitive to pyrogenic alkaloids and iodine-based disinfectants, making them good choices for farm hygiene.
17. **Piglet E. coli:** This bacterial infection responds well to commonly used disinfectants, so routine cleaning is important.
18. **Haemophilus parainfluenzae:** This pathogen is also responsive to standard disinfectants, emphasizing the importance of good biosecurity.
19. **Leptospira:** Sensitive to 3% bleach and benzalkonium bromide. Effective disinfection is key to preventing leptospirosis.
20. **Eperythrozoon:** This organism can be killed with 0.5% carbolic acid or by maintaining a temperature of 5°C for 15 days.
21. **Toxoplasma:** Common disinfectants are sufficient to eliminate this parasite, though thorough cleaning is necessary.
22. **Pig Coccidia:** Fire alkali (such as sodium hydroxide) or regular disinfectants can be used to control coccidiosis in pigs.
Always consult a veterinarian before implementing any disinfection protocol, as specific conditions may require tailored approaches. Proper hygiene and biosecurity measures are critical in preventing and managing pig diseases.
