Cooperative Binding and Chirogenesis in an Expanded Perylene Bisimide Cyclophane.

The encapsulation of more than one guest molecule into a synthetic cavity is a highly desirable yet a highly challenging task to achieve for neutral supramolecular hosts in organic media. Herein, we report a neutral perylene bisimide cyclophane, which has a tailored chiral cavity with an interchromophoric distance of 11.2 Å, capable of binding two aromatic guests in a π-stacked fashion.

Exploring extended-spectrum beta lactamase resistance in Vibrio parahaemolyticus and Vibrio cholerae within the tropical mangrove ecosystem of southwest India.

Multidrug-resistant pathogenic vibrios are a crisis of concern as they cause multiple illnesses, including gastroenteritis in humans and acute hepatopancreatic necrosis in aquaculture. In the current study, we investigated the prevalence of the beta-lactamase gene CTX-M-group 1 in Vibrio spp. (Vibrio cholerae and Vibrio parahaemolyticus) from the water and sediment of urban tropical mangrove ecosystems of Kerala, southwest India.

Prevalence of Extended-Spectrum Beta-Lactamase Resistance and CTX-M-Group 1 Gene in from the Water and Sediment of Urbanized Mangrove Ecosystems of Kerala.

The study aimed to determine the prevalence of extended-spectrum β-lactamase resistance and CTX-M-group 1 gene in from the water and sediment of three urbanized mangrove ecosystems of Kerala. A total of 119 isolates were screened for antibiotic susceptibility to 16 antibiotics. According to the phylogenetic analysis of isolates, nonpathogenic group A and pathogenic group D (29.

Screening of tropical estuarine water in south-west coast of India reveals emergence of ARGs-harboring hypervirulent Escherichia coli of global significance.

The goal of this study was to investigate the involvement of a tropical Indian estuary in the emergence of antibiotic resistance genes (ARGs)-harboring hypervirulent E. coli of global significance. A total of 300 E.

Antibiotic resistance and virulence genes of extraintestinal pathogenic Escherichia coli from tropical estuary, South India.

Introduction: Escherichia coli strains can cause a variety of intestinal and extraintestinal diseases. Extraintestinal pathogenic E. coli (ExPEC) strains have the ability to cause severe extraintestinal infections.

Antibiotic Resistance of Escherichia coli Serotypes from Cochin Estuary.

This study aimed at detecting the prevalence of antibiotic-resistant serotypes of Escherichia coli in Cochin estuary, India. E. coli strains were isolated during the period January 2010-December 2011 from five different stations set at Cochin estuary.
