Prevalence and identification of Candida sp. in pregnant women using VITEK-2

Background: Candida sp. is seen in several areas of body such as, mouth, groin area including vagina and digestive tract as thrush or gastroenteritis. The slide-culture technique and the VITEK-2 automated system were used for species-identification of the fungus; nonetheless, a gold standard or any first identification method would have inherent errors in arriving at a correct identification of a microorganism at species level.Methods: Morphological fungal criteria were ascertained with germ tubes, glucose agar, sugar fermentation and sugar assimilation tests Candida from vaginal swabs and other clinical samples of 85 infected pregnant women with diabetes, by growing swab lots on Sabouraud’s Dextrose Agar (SDA) plates, the slide culture technique and the VITEK-2 automated system.Results: Of 85 patients, 122 isolates in SDA culture were determined as 7 Candida sp.  with number of isolates of each species, as follows: 47 C. albicans, 9 C. famata, 11 C. glabrata, 13 C. guilliermondii, 8 C. krusei, 3 C. parapsilosis and 37 C. tropicalis from vaginal swabs. From 60 vaginal swabs, 46 urine samples and 12 throat swabs it was seen that C. albicans was most prevalent. However, withVITEK-2, 201 fungal strains were identified; Candida sp. was isolated in all samples: 59 C. albicans, 19 C. famata, 21 C. glabrata, 23 C. guilliermondii,18 C. krusei, 13 C. parapsilosis and 48 C. tropicalis.Conclusions: The most prevalent species among the isolated fungi was C. albicans, causing VC in diabetic pregnant women

Mineralogical Characteristics of Hematitic Iron Ore: A Geometallurgical Study on Ore from Eastern India

After being subjected to geometallurgical evaluation, the iron ores from Singhbhum Bonai-Keonjhar region, eastern India, have been designated as dense martite microplaty hematite high-strength ore (dM-mH-hs ore), massive dense martite microplaty hematite high-strength ore (mdM-mH-hs ore), schistose microplaty hematite low-strength ore (smH-ls ore), microplaty hematite powdery ore (mH-p ore), vitreous goethitic ore (vG ore), and ochreous goethitic ore (oG ore) end members, with varied strengths attributed to the microporosity levels. The first four variants form typical high-grade run-of-mines (ROMs) (hard, soft and powdery iron ore variants, e.g., ROM-HIO, ROM-SSIO, and ROM-PBD, respectively) with better amenability to beneficiation. In contrast, oG and vG ore end members form ROM lateritic iron ore (ROM-LIO) with poor amenability to beneficiation, having relatively higher concentrates of alumina (~3–6 wt%) due to the complex mineral chemistry of goethite and altered hematite. Banded hematite jasper (BHJ) is a very low-grade siliceous end member. In a mining operation, the ROMs may have the attributes of several combinations of the above-stated end members and ROM variants. The designated end members present in the ROMs determine their liberation, mineralogical processes, geometallurgical characteristics, amenability to beneficiation, product grade and recovery
