Monitoring Influenza A (H1N1, H3N2), RSV, and SARS-CoV-2 Using Wastewater-Based Epidemiology: A 2-Year Longitudinal Study in an Indian Megacity Covering Omicron and Post-Omicron Phases.

The bourgeoning field of wastewater-based epidemiology (WBE) for the surveillance of several respiratory viruses which includes Influenza A, H1N1pdm09, H3N2, respiratory syncytial viruses (RSV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is of interest for public health concerns. However, there are few long-term monitoring studies globally. In this study, respiratory viruses were detected and quantified from 11 sewer sheds by utilizing reverse transcription-quantitative polymerase chain reaction analysis in Pune city, India, from Jan 2022 to Dec 2023.

Genomic surveillance reveals early detection and transition of delta to omicron lineages of SARS-CoV-2 variants in wastewater treatment plants of Pune, India.

The COVID-19 pandemic has emphasized the urgency for rapid public health surveillance methods to detect and monitor the transmission of infectious diseases. The wastewater-based epidemiology (WBE) has emerged as a promising tool for proactive analysis and quantification of infectious pathogens within a population before clinical cases emerge. In the present study, we aimed to assess the trend and dynamics of SARS-CoV-2 variants using a longitudinal approach.

Sneathia species in a case of neonatal meningitis from Northeast India.

Here we report the detection of Sneathia species most closely related to Sneathia sanguinegens, an infrequently reported bacterium, in the cerebrospinal fluid of a neonate by a culture independent method. Even though on rare occasions, this bacterium was isolated previously from the blood of neonatal bacteraemia cases. To the best of our knowledge there exists no previous report of detection of S.

Alkalistable xylanase production by alkalitolerant Paenibacillus montaniterrae RMV1 isolated from red mud.

The alkalitolerant and xylanolytic bacterial strain (RMV1) isolated from red mud pond was identified as Paenibacillus montaniterrae based on both biochemical and 16S rDNA sequence analysis. The RMV1 bacterial isolate produced alkalistable and thermostable endoxylanase active over a broad range of pH (4.0-11.

Determination of total cholesterol in serum by cholesterol esterase and cholesterol oxidase immobilized and co-immobilized on to arylamine glass.

Commercial cholesterol esterase from bovine pancreas and cholesterol oxidase from Brevibacterium recombinant type have been immobilized individually and co-immobilized on to arylamine glass beads (pore diameter, 55 nm) through diazotization. A method for discrete analysis of total cholesterol in serum was developed employing individually immobilized cholesterol esterase (0.36 mg/50 mg of glass beads) and cholesterol oxidase (0.
