BACKGROUND Reports on the composition of oral bacteriome in Arabs are lacking. In addition, the majority of previous studies on other ethnic groups have been limited by low-resolution taxonomic assignment of next-generation sequencing reads. Furthermore, there has been a conflict about the existence of a 'core' bacteriome. OBJECTIVE The objective of this study was to characterize the healthy ...

The emerging clinical importance of staphylococcal infections prompted us to establish a reference database for partial RNA polymerase B (rpoB; nucleotides 1444-1928) gene sequences from type strains of all staphylococcal species and subspecies. This database correctly identified 55 clinical staphylococcal isolates; all were correctly identified at the species level. At the subspecies level, rp...

the genus artemisia containing more than 500 taxa at the specific or subspecific level. thirty-four species of genus artemisia have been reported in iran, which from the viewpoint distribution, density and coverage is the most important genera of plant. since the still has not been achieved a general system for the classification and phylogeny, in this research tried with evaluation of chloropl...

Vulvovaginal candidiasis is caused by the increasing number of Candida species as normal flora in the vagina. To assess the transmission rout as well as to determine the suitable antifungal drugs for treatment, the exact identification of Candida species is crucial. Therefore, earlier detection of infection allows quick initiation of antifungal therapy with a greater probability for improved su...

Phytoplankton taxa composition of the Caspian Sea were evaluated by using samples collected at 12 stations along the Iranian coast of the Caspian Sea between 1996 and 2010. This study identified 158 phytoplankton species consisted of diatoms (70 species), dinoflagellates (23 species), chlorophytes (29 species), cyanophytes (31 species), and euglenoids (5 species). The dominant species were the...

oil pollutions are widespread environmental pollutants. most of the studies have been focused on the biodegradation of these pollutions. unfortunately, the information on the microflore of the polluted regions especially for microalgae is limited. in this research, we have focused on masjed soleiman; one of the most oil polluted cities in iran. soil and water samples were collected from differ...

background: in the present study, a pcr-rflp based molecular technique was designed to rapid identification of der­matophytes in clinical specimens. skin scrapings obtained from human cases suspected to dermatophytosis were studied in or­der to identify involved etiological fungi. methods: in this experimental study, the specimens (skin scrapings) of patients referred to mycology department of ...
