Francisella noatunensis subsp. orientalis (Fno) is the causative agent of piscine francisellosis, an emerging infectious disease in Asia and Latin America. In this study two outbreaks of francisellosis were diagnosed in the UK on the basis of histopathology, electron microscopy, PCR, bacterial isolation and fulfillment of Koch's postulates. Furthermore, a phenotypic fingerprint based on biochem...

Introduction: Helicobacter pylori (H. pylori), is a bacterium responsible for upper gastrointestinal tract diseases. The 16s rRNA is a common H. pylori gene which are usually preferred for diagnosis purpose. The aim of this study was to determine the prevalence and abundance of 16s rRNA in fecal samples and also evaluate correlation between the level of 16s rRNA and activities of the cytokine...

An indigenous fungal strain was isolated from Indian Kolar Gold Field mine soil. The isolate was heterothallic, branched septate, deeply floccose, fast-growing, dull green with white background conidial columnar mycelium from Aspergillus section Fumigati. Diverse metabolic patterns of the isolate exhibit high metal, thermal resistance which grews well from 28 ± 1 degrees C to 37 degrees C and p...
