Antibacterial Efficacy of the Compound Preparation of Traditional Chinese Drug on System Fungi Reside in Faecal Specimen of Pigeon

Abstract:

To investigate the efficacy of the compound preparation of traditional Chinese drug which is named KZY-2) on system fungi reside in faecal specimen of pigeon, the 66 faecal specimen of pigeon were collected from columbary of local park and residents.Each specimen which weigh 2.0g was mixed with 10ml sterile saline and the supernatant which volume was 1ml was incubated with the same volume drug which concentration were 200mɡ/ml,100mɡ/ml and 50mɡ/ml respectively at 37°C.After 24h,48h and 72h, the isolated positive rates of Cryptococcus neoformans and Candida albicans were calculated. Candida albicans was identified by gram staining, budding development, chlamydospore formation, sugar fermented test,sugar assimilated test and Cryptococcus neoformans was identified by gram staining,sugar fermented test,sugar assimilated test,urease tests,caffeic acid test, Hiss capsule staining.Results showed that the isolated positive rates of Cryptococcus neoformans and Candida albicans were 27.3%（18/66） and 16.7%（11/66） without drug action, KZY-2 could reduce the isolated positive rates of Cryptococcus neoformans and Candida albicans(P<0.05 and P<0.05).The drug concentration and action time could significantly affect the isolated positive rate which was negative correlation between them, higher drug concentration and longer incubation time,more lower the positive rate, especially the isolated positive rates of Cryptococcus neoformans are reduced 77.7%（6.1/27.3）which incubated with 200mɡ/ml drug after 72h compared with the control group.These results indicate The KZY-2 have good germicidal efficacy on Cryptococcus neoformans and Candida albicans isolated from faecal specimen of pigeon.
