Plasmid-Mediated AmpC β-Lactamase and Genes Among Gram-Negative Clinical Isolates.

Background: Antibiotic resistance mediated by the production of extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases is posing a serious threat in the management of the infections caused by Gram-negative pathogens. The aim of this study was to determine the prevalence of two AmpC β-lactamases genes, and , in Gram-negative bacterial isolates.

Materials And Methods: A total of 1151 clinical samples were obtained and processed at the microbiology laboratory of Annapurna Neurological Institute and Allied Science, Kathmandu between June 2017 and January 2018.

Comparative Study of GeneXpert MTB/RIF Assay and Multiplex PCR Assay for Direct Detection of Mycobacterium tuberculosis in Suspected Pulmonary Tuberculosis Patients.

Pulmonary tuberculosis (PTB) is one of the major infectious diseases in developing countries. The objective of this study was to compare rapid diagnostics technique, GeneXpert MTB/RIF (GeneXpert) and Multiplex PCR assay (MPCR) targeting IS6110 segment and mpb64 gene for direct detection of Mycobacterium tuberculosis (MTB) in suspected PTB patients. A cross sectional study was carried among 105 sputum samples from suspected PTB patients to evaluate GeneXpert and Multiplex PCR who visited National Tuberculosis Center, Nepal.

Intestinal protozoan parasitic infection among school children.

Background: Intestinal protozoan parasitosis is highly prevalent among general population, majority of them are children. The objective of the study is to find out the prevalence of intestinal protozoan infection in school children of Sindhuli.

Methods: Stool samples were collected from school children of Sindhuli in June 2011 and investigated in National Institute of Tropical Medicine and Public Health Research, Laboratory by using formal-ether concentration method.
