Effective Prevention and Control of Rabbit Pasteurellos

Certainly! Here's a revised version of the text with enhanced clarity, precision, and a more engaging and personable tone:

Section 1: The Onset of Pasteurella Multocida in Rabbits

It's not uncommon for healthy rabbits to harbor Pasteurella multocida in their nasal mucosa and tonsils. However, these bacteria typically only cause illness when the environment becomes unfavorable or the rabbit's immune system is compromised. Factors such as poor husbandry, unbalanced nutrition, longdistance transport, parasitic infections, sudden changes in feed, overexertion, low temperatures, humidity, overcrowding, or inadequate ventilation can weaken a rabbit's defenses, allowing the bacteria to take hold and cause an infection. Infected rabbits excrete toxins that can contaminate the feed, water, and utensils in their environment, leading to the spread of the disease to other healthy rabbits. Additionally, the bacteria can be transmitted through the skin and mucous membranes of healthy rabbits via wounds, facilitated by bloodsucking insects.

Section 2: Preventive Measures for Pasteurella Multocida in Rabbits

1. Enhanced Husbandry and Sanitation: Pay close attention to prevent rabbits from catching colds; be cautious when trimming their fur to avoid skin cuts. Regularly inspect breeding farms, promptly removing positive cases. Isolate new rabbits upon arrival before introducing them to the group. And don't forget to schedule regular vaccinations for the rabbit population.

2. Cleaning and Disinfection: Since Pasteurella multocida is susceptible to common disinfectants, regular use of 3% lysol solution or 20% lime milk for cleaning pens, cages, and areas can significantly reduce the risk of infection. Also, washing feeding utensils with 2% lye water can be effective.

3. Vaccination: Regularly administer the Pasteurella multocida蜂胶灭活疫苗 or the combined兔瘟+Pasteurella multocida蜂胶二联灭活疫苗 to your rabbits.

Section 3: Treatment Methods for Pasteurella Multocida in Rabbits

When Pasteurella multocida is detected in a rabbit flock, it's advisable to cull rabbits showing obvious symptoms promptly. For asymptomatic rabbits, administer the Pasteurella multocida蜂胶灭活疫苗 as an emergency preventive measure to bolster their immunity quickly.

For rabbits with mild symptoms, isolation and treatment are recommended. Administer penicillin intramuscularly at a dose of 50,000 units per kilogram of body weight, twice daily, for 3 to 5 days. Alternatively, you can use streptomycin intramuscularly at a dose of 10,000 units per kilogram, twice daily, for the same duration. Oral administration of tetracycline, chlortetracycline, or oxytetracycline can also be effective.

For highquality breeding rabbits suffering from acute Pasteurella multocida, an antiseptic serum can be used. Inject 2 to 3 ml subcutaneously per kilogram of body weight, followed by another dose 8 hours later. To enhance the treatment's effectiveness, a combination of 400,000 units of penicillin and 500,000 units of streptomycin can be administered intramuscularly.

In cases of chronic disease, use penicillin or streptomycin solutions for nasal drops. Continue the treatment, and if the rabbit shows no signs of nasal discharge within 20 days, it can be considered recovered.

During treatment, provide rabbits with nutritious feed to boost their immunity. If many rabbits are affected, add a small amount of furazolidone premix to their concentrate feed, at a rate of 1,000 to 2,000 grams per ton of feed.

We hope these preventive measures for Pasteurella multocida can be of assistance to you.
