Effective Prevention and Treatment of Rabbit Colibacill

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

Part 1: Transmission Routes of Rabbit E. coli Infection

Escherichia coli, commonly known as E. coli, is widely present in the natural environment, making it possible for rabbits to contract the disease throughout the year. Poor management, feed spoilage, sudden changes in feed or weather, and unsanitary living conditions can all disrupt the balance of the normal gut flora in rabbits, weakening their resistance and leading to a surge in the number of E. coli present in their intestines. This imbalance can trigger an outbreak of E. coli in rabbits. Additionally, E. coli infections can also occur as a secondary condition following other diseases, such as coccidiosis.

E. coli infections can affect rabbits of all ages, but the disease is most prevalent in young rabbits aged 1 to 4 months, especially those just before and after weaning. The incidence and mortality rates are particularly high during this period, with adult rabbits rarely falling ill.

Part 2: Clinical Symptoms of Rabbit E. coli Infection

The primary symptoms of E. coli infection in rabbits include watery or jellylike diarrhea and severe dehydration, often leading to death. Early signs in affected rabbits may include listlessness, rough coat, loss of appetite, abdominal swelling, and tiny, stringy feces with jellylike mucus. As the condition worsens, rabbits may develop watery diarrhea, with their anal and hind leg fur often soiled with large amounts of mucus or feces. Other symptoms include cold extremities, teeth grinding, drooling, sunken eyes, and rapid weight loss, typically resulting in death within a few days.

Acute cases may present with sudden death without any prior symptoms. Newborn kits often suffer from acute E. coli infections, which typically occur between 5 to 7 days after birth. Affected kits may exhibit yellowish watery diarrhea and abdominal distension, with high mortality rates. Unweaned kits and young rabbits may present with severe diarrhea, releasing pale yellow watery feces that contain mucus.

Part 3: Prevention and Treatment of Rabbit E. coli Infection

1. Enhance Management: E. coli infections are difficult to treat once they occur, so prevention is key. Owners should ensure proper management, as the disease is closely linked to feed and hygiene. Most cases are caused by feed, so it's important to provide a balanced diet rich in roughage and to control the levels of energy and protein. Always inspect feed before feeding to ensure it is free from mold and other contaminants. Avoid sudden changes in feed and make any transitions gradual. Also, maintain low humidity and a clean, dry environment in the rabbitry.

2. Maintain Hygiene: Regularly disinfect the rabbitry. E. coli is relatively susceptible to disinfectants, so routine cleaning is crucial. Additionally, take steps to prevent contamination from mosquitoes, flies, and rodents.

3. Implement Vaccination and Prophylaxis: For weaned kits, consider adding medications like furazolidone, oxacillin, norfloxacin, or chloramphenicol to their feed to prevent disease. Alternatively, you can introduce a 0.5% to 1% microecological preparation into their diet for 5 to 7 days to help prevent E. coli infections. For rabbitries that frequently experience E. coli outbreaks, consider administering the E. coli polyvalent inactivated vaccine or multivalent vaccine for immunization.

By following these preventive measures, we hope that owners will recognize the dangers of E. coli infections in rabbits and take the necessary steps to manage and prevent them effectively.

This revised text aims to provide a clear, precise, and engaging description of the rabbit E. coli infection, its transmission, symptoms, and prevention strategies.
