鸡白色念珠菌的分离鉴定及其防治措施

目的]寻找鸡白色念珠菌的有效防治措施。方法]近10年来,从湖北省100多个蛋鸡场收集鸡白色念珠菌病料,对病料进行白色念珠菌的分离和鉴定,探讨该病的初步诊断方法和防治措施。结果]从832份鸡病料中分离到86株白色念珠菌。从2只鸡的嗉囊炎症部位涂片镜检结果发现,有卵形生芽的或不生芽的酵母状细胞和假菌丝。该病的诊断应以流行病学、症状及病理变化等资料为依据,并结合病原学检查。结论]可通过向健康鸡群定期投喂"真菌通治"等生物制剂,也可在饲料中添加5.00%大蒜、维生素和0.05%龙胆紫水,改善鸡舍环境条件等措施来预防鸡白色念珠菌。发病鸡则应立即隔离消毒,喂服制霉菌素。

Separation and Identification of Candida albicans in Chicken and its Control Measures

Objective] The research aimed to seek the effective control measures against Candida alhicans in chicken.Method] In recent ten years,the diseased samples were collected from more than 100 laying-hen farms of Hubei province.And the separation and identification of C.alhicans was made on the diseased samples to discuss the primary diagnosis method and control measures for this disease.Result] 86 strains of Candida alhicans were separated from 832 diseased chicken samples.From the results of microscopic examination on the inflammation part of craw in 2 chicken,oval gemmiparous or disgemmiparous yeast-shaped cells and pseudomycelium were found.The diagnosis of this disease should be combined with the pathogenic examination on basis of the data of epidemiology,symptoms and the pathological changes.Conclusion] To prevent C.alhicans in chicken,measures such as regularly feeding biological preparations such as "Zhengjuntongzhi" to healthy chicken folk,adding 5.00% garlic,0.05%gentian violet water and vitamin to the feed,improving the environmental conditions of henhouse should be taken.The diseased chicken should be immediately separated and sterilized,and fed with nystatin.
