detection of candida vulvovaginitis in clinical samples ; using direct polymerase chain reaction without dna extraction

چکیده
conclusions direct sample pcr has the potential to rapidly and accurately diagnose candida vulvovaginitis in patients, especially if sufficient samples are obtained. results the results showed that out of the 150 samples, 55 were positive and 63 samples were negative by both methods, and 32 samples were positive using the culture method, but negative by ds-pcr. all positive ds-pcr samples had > 107 yeast or conidia cells/ml. the sensitivity and specificity of ds-pcr were calculated as 63.2% and 100%, respectively. patients and methods in the current study, totally 150 sexually active women participated. vaginal discharge samples were collected using two sterile dacron swabs that were immediately placed in two tubes each containing 1 ml of distilled water. one of the tubes was used for conventional culture methods whereas the other one was used for ds-pcr without dna extraction. the number of yeast cells in each sample was counted. background vulvovaginal candidiasis (vvc) is a common disease which infects women. the current study investigated the performance of direct sample polymerase chain reaction (ds-pcr) method to detect candida spp. in clinical samples of vulvovaginitisto compare the results to those of standard microbiological laboratory methods. objectives the current study aimed to further simplify the dna extraction procedure, and shorten the time required for isolation and identification by using direct pcr to identify candida vulvovaginitis without dna extraction from samples or colonies.

Background: Chronic lupoid leishmaniasis (CLL) is a chronicform of cutaneous leishmaniasis that is usually resistant to antileishmania agents and leishmania is not seen in the histologicsections. We used polymerase chain reaction (PCR) to detectleishmania DNA in CLL specimens.Method: This descriptive cross sectional study was done on20 paraffin embedded specimens of CLL cases referred to theder...

Detection and enumeration of bacteria in soil by direct DNA extraction and polymerase chain reaction.
In order to develop a rapid and specific detection test for bacteria in soil, we improved a method based on the polymerase chain reaction (PCR). Each step of the protocol, including direct lysis of cells, DNA purification, and PCR amplification, was optimized. To increase the efficiency of lysis, a step particularly critical for some microorganisms which resist classical techniques, we used sma...
