The incidence of Trichomonas tenax (T. tenax) in patients with acute ulcerative gingivitis has been demonstrated in several published reports. Metronidazole was known as the most effective drug for human trichomoniasis, however, drug resistance and toxicity appeared. This study was designed in vitro to investigate the inhibitory activity of Punica granatum (P. granatun) ethanol extract on the g...

OBJECTIVE To investigate the possible involvement of human trichomonads (Pentatrichomonas hominis and Trichomonas tenax) other than Trichomonas vaginalis in the aetiology of vaginal trichomoniasis. METHODS Vaginal swabs taken from women attending antenatal clinics were tested for Trichomonas vaginalis by traditional assays (wet-mount microscopy and InPouch culture) and nucleic acid amplificat...

The hyperthermophilic, facultatively heterotrophic crenarchaeum Thermoproteus tenax was analyzed using a low-coverage shotgun-sequencing approach. A total of 1.81 Mbp (representing 98.5% of the total genome), with an average gap size of 100 bp and 5.3-fold coverage, are reported, giving insights into the genome of T. tenax. Genome analysis and biochemical studies enabled us to reconstruct its c...

The phosphorylation of glucose by different sugar kinases plays an essential role in Archaea because of the absence of a phosphoenolpyruvate-dependent transferase system characteristic for Bacteria. In the genome of the hyperthermophilic Archaeon Thermoproteus tenax a gene was identified with sequence similarity to glucokinases of the so-called ROK family (repressor protein, open reading frame,...

A 39 year old woman was admitted with fever and an exacerbation of asthma. The chest radiograph showed extensive bilateral lung infiltrates, but transtracheal needle aspiration did not reveal any infectious organisms. The bronchoalveolar fluid lavage contained a large number of Trichomonas tenax and an increased percentage of eosinophils. Corticosteroids provided a dramatic response. Because of...

buccal cavity as a compound ecosystem has always been ignored in parasitic infection studies; however it seems that studying on mouth and tooth prevalent parasitic infections is of great importance. in this study, from 120 patients of both sexes referred to faculty of dentistry, tehran university of medical sciences, iran, (2001-2002) 240 samples were taken from the plaques and calculus of dept...

In this paper we document the role of Phormium tenax as a nurse plant in unimproved pasture. We show that for our study area the regeneration of woody species was limited solely to P. tenax clumps with 22 native and one introduced regenerating woody species present. The number of woody species and of individual woody plants regenerating within P. tenax is not correlated with distance from the e...

Here, we report on the complete genome sequence of the hyperthermophilic Crenarchaeum Thermoproteus tenax (strain Kra1, DSM 2078(T)) a type strain of the crenarchaeotal order Thermoproteales. Its circular 1.84-megabase genome harbors no extrachromosomal elements and 2,051 open reading frames are identified, covering 90.6% of the complete sequence, which represents a high coding density. Derived...

A new approach of enhancing the adsorption capability of the widely used polymer adsorbent Tenax TA poly(2,6-diphenylene oxide) through its deposition on a nano-structured template is reported. The modified Tenax TA-coated silica nanoparticles (SNP) are incorporated as an adsorbent bed in silicon based micro-thermal preconcentrator (μTPC) chips with an array of square microposts embedded inside...

We report a case of human nasal myiasis caused by flower fly larva in a 14-year-old rural girl in Central Province of Iran. Entomological studies on larva showed the larva as Eristalis tenax which is a rarely cause of nasal myiasis. This is the first reported case of E. tenax larva causing human nasal myiasis in Iran.
