Blackwood et al. (1) assert that terminal restriction fragment length polymorphism (T-RFLP) data cannot be used to estimate the species level diversity of bacterial communities. While I do not argue with their analytical techniques, nor the interpretation of their results, their conclusion is essentially moot as T-RFLP techniques are rarely used (nor should they be used) to study the diversity ...

A PCR-restriction fragment length polymorphism (RFLP) analysis method that analyzes a part of the dnaJ gene was designed for the rapid and accurate identification of Staphylococcus spp. XapI or Bsp143I digestion of the PCR-generated products rendered distinctive RFLP patterns that allowed 41 reference species and subspecies to be identified with a high degree of specificity. The novel method wa...

conclusions several previous studies used pcr-rflp to genotype hbv; however, we showed the high risk to obtain atypical profiles, especially in advanced stages of chronic infection, with as results difficulties to genotype the virus. these profiles resulted from the accumulation of mutations during natural course of infection resulting in a modification in restriction sites for enzymes. so, we ...

background: molecular components of the dopamine receptor (drd3) play an important role in the pathophysiology of schizophrenia (scz). previous studies have demonstrated an association between the drd3 ser9gly polymorphism and scz but the results have been inconclusive. method: in this study, we investigated this controversial association between the ser9gly (a/g) polymorphism and scz using mal...

conclusions the results of the present study, compared to the previous studies, showed a significantly lower prevalence of cutaneous candidiasis. among candida species, c. albicans was still the most common infectious agent isolated from clinical samples. shifting toward non-albicans candida species was not confirmed in this study. in addition, our study revealed that there is a direct correlat...
