Recent studies on the vaginal microbiota have employed molecular techniques such as 16S rRNA gene sequencing to describe the bacterial community as a whole. Currently, methods for the lysis of bacterial cells are not standardised and there is potential for introducing bias into the results if some bacterial species are lysed less efficiently than others. This study aimed to compare the results of vaginal microbiota profiling using four different pretreatment methods for the lysis of bacterial samples 30 min of lysis with lysozyme, 16 hours of lysis with lysozyme, 60 min of lysis with a mixture of lysozyme, mutanolysin and lysostaphin and 30 min of lysis with lysozyme followed by bead beating prior to chemical and enzyme-based DNA extraction with a commercial kit.

Background: The composition of the microbiome in human body sites plays an important role in health. The vaginal environment is colonized by several species of bacteria that have a major influence on reproductive health. The advancement of sequencing technologies has made the assessment of the composition of the microbiota possible through microbial DNA extraction and sequencing. Therefore, it is of a paramount importance to select a sensitive and reproducible DNA extraction method, that facilitates isolation of microbial DNA with a sufficient quantity and purity, from microbial species living in the vaginal environment.

Clone Search Tools. The user simply collects the specimen using the provided swab, and then transfers the swab into the Swab Preservative. The Swab Preservative prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely.

DNA purification procedure consists of four steps and utilizes spin minicolumns with membranes which efficiently and selectively bind nucleic acids. When isolating from semen, DTT must also be used. A two-step washing stage effectively removes impurities and enzyme inhibitors. Our subscribers receive specially prepared offers, with attractive prices.

Rapid and efficient purification of high quality genomic DNA from human and animal mucosa membrane swabs including buccal, nasal, pharyngeal and vaginal swabs as well. The isolation protocol and buffer formulations were optimised for high isolation efficiency and DNA purity. The DNA purification procedure consists of four steps and utilises spin minicolumns with membranes which efficiently and selectively bind nucleic acids.

Background: Candida species are the second most common cause of vulvovaginitis worldwide. The purpose of this study was to identify the species of vaginal Candida isolates by using phenotypic and Multiplex PCR techniques. Methods: 91 isolates from patients admitted to Azadi hospital and Maternity hospital in Duhok city were collected.
