Evaluation of LAMP-based assays for carbapenemase genes.

. Rapid and accurate detection of carbapenem resistance is a critical requirement for the selection of appropriate therapy and initiation of infection control measures. Although several tests are available, their use is limited by one or more factors.

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.

Extra-intestinal salmonellosis in a tertiary care center in South India.

Introduction: The present study is a retrospective analysis of a total of 36 cases of bacteriologically proven extra-intestinal salmonellosis, managed at Nizam's Institute of Medical Sciences, between 1987 and 2012 (25 years). The extra-intestinal sites involved were the skin, cerebrum, spleen, ovary, synovium, and the skeletal muscle.

Methodology: The extra-intestinal specimens were first processed using standard methods.

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.

Brucella endocarditis - a series of five case reports.

Endocarditis due to brucellosis is considered a rare occurrence involving native, congenital and prosthetic valves. The diagnosis needs high degree of suspicion in culture negative endocarditis especially in those with history of exposure to farm animals. A positive culture in a susceptible patient confirms the diagnosis with 91% sensitivity.
