厌氧产黑色素杆菌群超微结构观察

Observation on the ultrastructure of black pigmented Bacteroides

目的：了解感染根管内产黑色素类杆菌（BPB）的定植情况，进一步探讨BPB与慢性根尖周炎临床症状的相关性。

OBJECTIVE To study the colonization of Black-pigmented bacteria ( BPB ) in infected root canals and discuss the correlation between Black-pigmented bacteria and clinical symptoms in chronic periodontitis .

类杆菌的超微结构观察产黑色素拟杆菌有效药物敏感性与不产黑色素拟杆菌略一致；

Observation on the ultrastructure of Bacteroides Species No difference between melaninogenicus and non - melaninogenicus .

结果：优势菌群为：牙龈紫质单胞菌、产黑色素类杆菌、齿垢密螺旋体、伴放线放线杆菌。

RESULTS : The dominant bacteria were gingival purple plasma unicellular bacteria , melaninogenicus , material alba spirochete and actinomyces .

又从58种药物中选择18种对产黑色素类杆菌进行抑菌试验，筛选出高效药物4种。

18 kinds of the 58 herbs were selected to test for bacteriostatic effect on B. melaninogenicus and 4 of them showed high effect by screening .

结果：产黑色素G厌氧杆菌和牙龈卟啉单胞菌的患者检出率分别是67.2%和60.9%。

Results : The positive rates of black pigmented anaerobic strains and Pg among the patients were 67.2 % and 60.9 % respectively .

牙龈卟啉单胞菌在病变部位和健康部位的检出株数分别是122株和85株，占产黑色素G厌氧杆菌检出株数的32.3%和35.9%，差异无统计学意义。

122 and 85 strains of Pg were isolated from diseased and healthy sites , which constituted 32.3 % and 35.9 % of the total isolated black pigmented anaerobic strains respectively .

方法对207株牙周临床分离的产黑色素G-厌氧杆菌分别进行脂酶试验、常规生化法鉴定和16SRRNA特异引物PCR鉴定。

Bacterial identification was performed by lipase test , conventional biochemical methods and PCR using specific primers with sequences of 16s rRNA .
