Its frequency was 9% among the examined swabs. There were 50% infection rates for both males as well females. The highest incidence (11.25%) found 21-40 years-old while lowest (6.66%) in 41-60 years-old. no significant variations relation to residency. association between T. tenax and dental caries noticed at a rate of 66.7%. In addition, different observed patients with some other oral disease...

The analysis of PAHs in environmental samples involves sampling, extraction, concentration and final analysis using GCMS. Traditional extraction of PAHs from a solid matrix, where much of the PAH reside, is a tedious and time consuming process. Thermal desorption (TD) can replace the traditional sample preparation step in the analysis scheme with a more efficient and direct method, which also e...

during a survey conducted on syrphidae fauna in guilan province (masuleh & lakan) in august 2006, some species of the genus eristalis latreille were collected and identified, of which e. similis (fallen) is newly reported from iran. the identification was confirmed by heikki hippa, swedish musem of natural history.

The sequencing, cloning, and expression of the pfp gene from Dictyoglomus thermophilum, which consists of 1,041 bp and encodes a pyrophosphate-dependent phosphofructokinase, are described. A phylogenetic analysis indicates that the enzyme is closely related to the pyrophosphate-dependent enzyme from Thermoproteus tenax. The recombinant and native enzymes share a high degree of similarity for mo...

entamoeba gingivalis and trichomonas tenax are protozoans that live in/on the teeth, gums and sometimes tonsils, and may cause periodontitis and gingivitis. the aim of this research was studying the frequency of buccal protozoa in patients referred to dentistry clinics of jundishapur university of medical sciences. in this cross-sectional study, samples were collected from the mouth of 200 pati...

PCR analysis in two unusual occurrences of trichomoniasis, trichomonal empyema due to Trichomonas tenax and Trichomonas vaginalis in an infant urine sample, allowed us to obtain rapid and accurate trichomonad species identification. The weak sensitivity of wet preparations and the low viability of the flagellates can be remedied by the PCR method.
