Candidiasis of pigeon

The disease is also called candidiasis, thrush and so on. It is a common fungal infection characterized by the formation of white pseudomembrane and ulcers in the mucosa of the mouth, pharynx, esophagus and bursa.

1. Pathogen

The main pathogen causing the disease is Candida albicans, which is small, oval, 2 ~ 4 microns wide and grows in the mouth, throat, esophagus and esophagus.

In the bag.

2. Pop special, automobile

Both young pigeons and adult pigeons are susceptible to the disease, and the disease is most likely to occur in young pigeons aged from 2 weeks to 2 months. With the excretion of feces and oral secretions of sick pigeons, pathogens pollute the surrounding environment, feed and drinking water, and infect healthy pigeons. In addition, the disease can also be transmitted through contaminated eggshells. Adverse factors such as poor environmental hygiene conditions and overcrowding of pigeons can induce the disease. 3. Clinical symptoms

At the initial stage, the mouth and throat of the affected pigeon were congested and flushed, and the secretions increased and showed a thick shape. The lesions gradually form small white spots, causing inflammation and swelling of the mouth, throat and bursa. In more serious cases, yellow plaque-like erectile appendages are produced in the mouth, pharynx, esophagus and sac, which will die due to respiratory disorders.

On autopsy, it was found that the folds of esophagus and bursa became thicker, eroded, or covered with yellow-white caseous pseudomembrane, and eroded or ulcerated membranes could be seen.

4. Diagnosis

A preliminary diagnosis can generally be made at the site of the disease. The most reliable diagnostic method is to gently scrape the secretion with a toothpick and examine it under a microscope. if budding bracts (similar to yeast) and mycelium are found, it is Candida albicans.

5. Prevention and treatment

At present, there is no vaccine to prevent the disease, mainly to strengthen drug prevention and feeding management, improve environmental hygiene conditions, ensure ventilation and dryness of pigeon houses, eliminate all factors that are not conducive to pigeon health and improve them in time.

The following measures can be taken in treatment:

The main results are as follows: (1) during individual treatment, 2% boric acid solution can be injected into the wordy bag of sick pigeons for disinfection, and the ulcer foci on oral mucosa can be coated with iodoglycerol, and 1: 2000 copper sulfate aqueous solution can be used as drinking water for 3 ~ 5 days. (2) give nystatin 20 mg each time, twice a day for 7 days. Or take Kemusheng tablets orally, 30 mg per kilogram of body weight, twice a day for 7 days.

(3) for large groups, 50 ~ 100mg nystatin per kilogram of feed can be added for 7 days, while human cusq (1: 2000) is added to drinking water for 5 days, and vitamin An is supplemented to reduce the degree of pathological changes.
