Gram-positive bacteria

A tRNA-directed transcription antitermination mechanism is common in Gram-positive bacteria, regulating the expression of aminoacyl-tRNA synthetase and amino acid biosynthesis genes.

由tRNA引導的轉錄抗終止機制普遍存在于革蘭氏陽性細菌中 ,調控氨酰 tRNA合成酶基因和與氨基酸合成有關的酶基因的表達 。

Methods 318 samples of vaginal secret were observed by wet mount, Gram stain and were cultured.

方法對318例女性患者陰道分泌物進行了濕片法檢查和革蘭染色顯微鏡檢查,并對陰道分泌物、宮頸分泌物及糞便分別進行了假絲酵母菌培養。

Methods Aggregate analysis was performed by applying normal sodium smear test under microscope associated with Gram stain and bacterial culture.

方法用生理鹽水涂片直接鏡檢結合革蘭染色與培養結果進行綜合分析。

9% saline solution and stained by Gram staining.
