objective(s):urinary tract infection (uti) caused by bacteria is one of the most frequent infections in human population. inappropriate use of antibiotics, often leads to appearance of drug resistance in bacteria. however, use of probiotic bacteria has been suggested as a partial replacement. this study was aimed to assess the antagonistic effects of lactobacillus standard strains against bacte...

The study was undertaken to elucidate the recent epidemiological status of salmonellosis in India. A total of 23 Salmonella isolates were recovered from different disease outbreaks in different geographical locations. The phenotypic analysis by serotyping, transmission electron microscopy and antibiogram profiles were able to classify the Salmonella isolates based on different serovars. The S. ...

Electrophoretic techniques were employed to study variation in chromosomal genes encoding enzymes and in the distribution of cryptic plasmids in the E. coli population of a human host over an 11-month period. Thirteen of the 15 enzymes studied were polymorphic, and mean genetic diversity per locus was 0.39. Among 550 clones isolated from fecal samples, protein electrophoresis revealed 53 distin...

We report an approach to the design of degradable polyelectrolyte-based films for the controlled release of siRNA from surfaces. Our approach is based on stepwise, layer-by-layer assembly of multilayered polyelectrolyte films (or "polyelectrolyte multilayers", PEMs) using siRNA and a hydrolytically degradable poly(β-amino ester) (polymer 1). Fabrication of films using siRNA sequences for green ...
