Cryptosporidium species are one of the most common causes of gastrointestinal infection in humans around the world. This study has aimed to investigate the hyper variable region of the 18S rRNA gene in Cryptosporidium for exact parasite identification. DNA was extracted from 26 fecal samples from which initially Cryptosporidium oocysts were identified by Ziehl-Neelsen acid-fast , Auramine pheno...
The goal of this study was to evaluate the effect of the specimen-processing method that uses the detergent C18-carboxypropylbetaine (CB-18) on the sensitivity of acid-fast bacillus (AFB) staining. Vietnamese immigrants with abnormal chest radiographs provided up to three sputum specimens, which were examined for acid-fast bacilli by use of direct auramine and Ziehl-Neelsen staining. The remain...
Hydrodynamic cavitation for the degradation of model dye wastewater containing Auramine O dye was investigated using vortex diode as a cavitating device. The effect of different operating parameters such as inlet pressure, initial dye concentration and flow rate on degradation rate of auramine O was studied in the concentration range of 80 mg/L to 1200 mg/L. The cavitational yield of the cavita...
OBJECTIVES To assess the efficacy of the Kato-Katz technique and to re-evaluate other routine procedures conducted in the Microbiology Clinical Laboratory at Sultan Qaboos University Hospital (SQUH) and to throw light on the prevalence of intestinal parasitic infections among a small group of food handlers in Muscat. METHOD Faecal samples collected from food handlers were examined using five ...
Cryptosporidium is an obligate intracellular protozoan parasite infecting a wide range of hosts. The current study investigated the genetic profile of Cryptosporidium species in calves in Liverpool, England. Fifty-two calve fecal samples were collected from a farm and initially screened by Auramine phenol, modified Ziehl-Neelsen and ELISA. PCR analysis of 18S rRNA gene was carried out for the p...
objective the aim of this study was to compare the sensitivity and specificity of acid fast and auramine-rhodamine staining and multiplex pcr for the detection of mycobacterium tuberculosiscomplex and non tuberculosis mycobacteria on formalin fixed paraffin embedded tissues (ffpe) materials and methods forty cases of ffpe pleural and bronchial tissue with chronic granulomatous inflammation and ...

The adsorption behaviour of Methyl violet and Auramine yellow from aqueous solution onto Stishovite clay was investigated as a function of parameters such as initial dye concentration, contact time, p and temperature. The Langmuir and Freundlich adsorption models were applied to describe the equilibrium isotherms. Adsorption followed pseudo-second order model. The experimental data fitted well ...
