神农架川金丝猴源肠道粪肠球菌的分离与鉴定
Isolation and identification of intestinal Enterococcus faecalis from golden snub-nosed monkeys in Shennongjia National Natural Reserve
摘要
Abstract
Eight strains with obvious antibacterial effect were isolated from the contents of the intestinal of healthy wild golden snub-nosed monkeys (Rhinopithcus roxellana) in Shennongjia by differential cultivation,morphology observation and antimicrobial tests.They were identificated as Enterococcus faecalis by physiological and biochemical identification,and 16S rRNA sequence analysis.Of which,two good safety strains were screened through the detection of virulence factors and the animal acute toxicity test.Their characteristics of tolerating gastrointestinal environment (low pH,high bile) and growth were examined.The results showed that E.faecalis dlt7a and dlt7b were safe,and probiotic for the body,and they own the features that rapid propagation,a strong ability to withstand the gastric acid and intestinal bile salt.They may be used as candidate probiotics strains for golden snub-nosed monkeys in the future.关键词
