The purpose of this current study was molecular typing of extended-spectrum β-lactamases (ESBLs) encoded by ESBLs genes of 56 Escherichia coli isolated from environment lake water (n=15), food samples (n=20) and from clinical specimens (n=21). The prevalence of CTX-M type ESBL-producing Escherichia coli was 76.5% (39 of 51 Escherichia coli) in cont...

Catharnthus roseus (periwinkle) is used as an important plant in traditional medicine for a long time. The cycotoxicity of the different extracts of leaves and flowers of Catharanthus roseus were examined by brine shrimp lethality bioassay. However, methanol extract of leaves and methanol extract of flowers exhibited quite potent activity in brine...

The aim of this study was to determine the chemical and microbiological analysis of soya cheese and compare with cow milk cheese and raw soya. Fat content is lower and protein content is higher in soya cheese than cow milk cheese. Moisture, ash, fat, total carbohydrate, total energy, pH, total chlorides and Total solids are significantly higher in...

Total load of bacteria, fungi and pathogenic microorganisms in muscle-and-skin samples of 12 different species of fish were analyzed. Highest standard plate count (5.1 x 10⁶ cfu/g) was observed in Batashi (Clupisoma atherinoides) and lowest (2.3 x 10⁵ cfu/g) in Rui (Labeo rohita). Total bacterial load was almost similar in case of other fishes. Mol...

Polypore mushroom was found to be rich in protein, fiber and cellulose. Polypore mushroom is found to grow on rotting hard wood logs. So, attempt was made to cul- tivate the species in laboratory condition. The present paper describes the process of cultivation of polypore mushroom in laboratory condition. The selected substrates (e.g. mango saw du...
