background and objective : given the importance of rapid diagnosis for fungal rhinosinusitis, this study aimed to evaluate the use of nested pcr to identify aspergillus and mucor species in clinical samples from patients with suspected fungal rhinosinusitis. methods : functional endoscopic sinus surgery specimens were collected from 98 patients with rhinosinusitis from 2012 to 2013. all samples...

Ultrasound (US), Thermo-sonication (TS) and High Pressure Homogenization (HPH) were studied as tools to inactivate the spores of Penicillium spp. and Mucor spp. inoculated in distilled water. For US, the power ranged from 40% to 100%, pulse from 2 to 10 s, and duration of the treatment from 2 to 10 min. TS was performed combining US (40-80% of power, for 8 min and pulse of 2 s) with a thermal t...

The reaction of benzil, 1-alkyl-2-arylethanediamine dihydrochloride and sodium acetate trihydrate gave the target molecule dihydropyrazine derivatives 30-34. The compounds have been characterized on the basis of their FT-IR, 1H NMR and 13C NMR spectroscopies. All the compounds are screened for their antibacterial activity against Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aerugin...

Bartnicki-Garcia, S. (Rutgers, the State University, New Brunswick, N. J.), and Walter J. Nickerson. Thiamine and nicotinic acid: Anaerobic growth factors for Mucor rouxii. J. Bacteriol. 82:142-148. 1961.-Mucor rouxii requires preformed thiamine and nicotinic acid for anaerobic growth. Such requirements are not manifested during aerobic incubation. Aerobically, the fungus was shown to be able t...

Gale, Glen R. (Veterans Administration Hospital and Duke University Medical Center, Durham, N.C.). Effects of the antifungal peptide Ro 2-7758 on morphology of Mucor corymbifera. J. Bacteriol. 85:833-837. 1963.-Hyphae of Mucor corymbifera grown in the presence of the antifungal peptide, Ro 2-7758, were examined in an electron microscope. The predominant change, compared with control hyphae, was...

Environmental conditions and airborne myco£lora were measured concurrently in 10 turkey confinement houses during warm and cold weather. The following variables in the environment were measured: numbers of feedand litter-associated yeast and mold fungi, temperature, relative humidity, airspeed, carbon dioxide and ammonia concentration, airborne bacteria, and airborne particulate mass, particle ...

Numerous species of filamentous fungi were isolated from lemon on different plantations in the province of Tucuman, Argentina. The techniques suggested by the Subcommittee of Antifungal Susceptibility of the National Committee for Clinical Laboratory Standards, (USA) were adapted. The effect of three different concentrations of the fungicides imazalil, guazatine, SOPP and thiabendazole on the f...
