Genomic Clues of a Multidrug-Resistant Bacterium from Cultured Domestic Silkworm (Bombyx mori L.).

Enterobacter sp. strain ASE was isolated from the gut of an infected domestic silkworm (Bombyx mori L.; Lepidoptera: Bombycidae).

Bio-molecule functionalized rapid one-pot green synthesis of silver nanoparticles and their efficacy toward the multidrug resistant (MDR) gut bacteria of silkworms ().

The present study aimed to synthesise bio-molecule functionalized silver nanoparticles (AgNPs) using leaf extract from mulberry variety S-1635 ( L.) and to explore its antibacterial efficacy against multidrug resistant (MDR) gut bacteria isolated from natural infection observed from silkworm larvae in rearing conditions. AgNPs formation was established by surface plasmon resonance at 480 nm.

Effect of feed supplementation with biosynthesized silver nanoparticles using leaf extract of Morus indica L. V1 on Bombyx mori L. (Lepidoptera: Bombycidae).

Herein, we report the synthesis of silver nanoparticles (AgNPs) by a green route using the aqueous leaf extract of Morus indica L. V1. The synthesized AgNPs exhibited maximum UV-Vis absorbance at 460 nm due to surface plasmon resonance.

Flocculating, emulsification and metal sorption properties of a partial characterized novel exopolysaccharide produced by Rhizobium tropici SRA1 isolated from Psophocarpus tetragonolobus (L) D.C.

A novel exopolysaccharide (EPS) was produced by a bacterium which was isolated from Psophocarpus tetragonolobus (L) D.C. and identified as 99% Rhizobium tropici SRA1 by 16S rDNA sequencing.

Green synthesis of silver nanoparticles: biomolecule-nanoparticle organizations targeting antimicrobial activity.

Since discovery of the first antibiotic drug, penicillin, in 1928, a variety of antibiotic and antimicrobial agents have been developed and used for both human therapy and industrial applications. However, excess and uncontrolled use of antibiotic agents has caused a significant growth in the number of drug resistant pathogens. Novel therapeutic approaches replacing the inefficient antibiotics are in high demand to overcome increasing microbial multidrug resistance.

Unregulated use of antibiotics in Siliguri city vis-a-vis occurrence of MAR bacteria in community waste water and river Mahananda, and their potential for resistance gene transfer.

The unregulated use of antibiotics, including therapeutic and prophylactic prescribing, in the fastest growing city of West Bengal, Siliguri, was studied indirectly from a random survey conducted on retail medicine sellers at their counters. Ciprofloxacin, ampicillin, norfioxacin and amoxycillin were the highest retailed antibiotics and 58% of the city pharmacies sold antibiotics even without prescriptions. To understand the influence of the extent of antibiotic use by the community on the collective bacterial flora in the aquatic environment, we have determined the fraction(s) of Standard Plate Count (SPC) bacteria resistant to different antibiotics and multiple antibiotic resistance (MAR) profile of resistant SPC isolates from two municipal open drains and Mahananda river water samples of Siliguri.
