Novel self-assembling conjugates as vectors for agrochemical delivery.

Background: Modern agricultural practises rely on surfactant-based spray applications to eliminate weeds in crops. The wide spread and indiscriminate use of surfactants may result in a number of deleterious effects that are not limited to impacts on the crop and surrounding farm eco-system but include effects on human health. To provide a safer alternative to the use of surfactant-based formulations, we have synthesised a novel, self-assembling herbicide conjugate for the delivery of a broad leaf herbicide, picloram.

Evaluation of LAMP Assay Using Phenotypic Tests and Conventional PCR for Detection of nuc and mecA genes Among Clinical Isolates of Staphylococcus spp.

Introduction: The purpose of this study is to develop a nuc and mecA gene specific Loop-mediated isothermal Amplification (LAMP) assay for rapid identification and detection of methicillin resistant Staphylococcus aureus among clinical isolates.

Materials And Methods: A total of 100 (70 from pus and 30 from blood), clinical isolates of Staphylococcus spp were screened for the nuc gene to differentiate between S.aureus and Coagulase negative Staphylococci (CONS) by a nuc gene specific LAMP assay.

Comparative Evaluation of Multiplex PCR and Routine Laboratory Phenotypic Methods for Detection of Carbapenemases among Gram Negative Bacilli.

Background: Carbapenem resistant pathogens cause infections associated with significant morbidity and mortality.

Objective: This study evaluates the use of Multiplex PCR for rapid detection of carbapenemase genes among carbapenem resistant Gram negative bacteria in comparison with the existing phenotypic methods like modified Hodge test (MHT), combined disc test (CDT) and automated methods.

Material And Methods: A total of 100 Carbapenem resistant clinical isolates, [Escherichia coli (25), Klebsiella pneumoniae (35) P.

Rapid detection and differentiation of dengue virus serotypes by NS1 specific reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay in patients presenting to a tertiary care hospital in Hyderabad, India.

Early and rapid detection of dengue virus (DENV) infection during the acute phase of illness is crucial for proper patient management and prevention of the spread of the infection. In the present study, the standardization and validation of a one step, four tube reverse transcription loop-mediated isothermal amplification assay (RT-LAMP) for rapid detection and serotyping of the DENV targeting NS1 gene using the Genie® II flourometer was carried out. The performance of the RT-LAMP was compared to RT-PCR, CDC 1-4 Real time PCR and the NS1 antigen ELISA, IgM and IgG anti DENV antibodies.

Unusual and rare manifestations of dengue during a dengue outbreak in a tertiary care hospital in South India.

Dengue is the most rapidly spreading mosquito-borne viral disease in the world, and as a larger proportion of the population is being affected, more unusual manifestations are being reported. Very few studies have documented unusual manifestations of dengue in South India. This prospective study was undertaken from July 2011 to June 2013 to document rare manifestations of dengue fever in 175 hospitalized patients.

Evaluation of LAMP assay using phenotypic tests and conventional PCR for detection of blaNDM-1 and blaKPC genes among carbapenem-resistant clinical Gram-negative isolates.

Carbapenem-resistant pathogens cause infections associated with significant morbidity and mortality. This study evaluates the use of the loop-mediated isothermal amplification (LAMP) assay for rapid and cost-effective detection of bla(NDM-1) and bla(KPC) genes among carbapenem-resistant Gram-negative bacteria in comparison with conventional PCR and existing phenotypic methods. A total of 60 carbapenem-resistant clinical isolates [Escherichia coli (15), Klebsiella pneumoniae (22), Acinetobacter baumannii (23)] were screened for the presence of carbapenemases (bla(KPC) and bla(NDM-1)) using phenotypic methods such as the modified Hodge test (MHT) and combined disc test (CDT) and molecular methods such as conventional PCR and LAMP assay.
