Background: Rapid fluorescent focus inhibition test (RFFIT), a neutralization-based assay for detecting rabies antibodies, is the gold standard. The National Action Plan for Dog Mediated Rabies Elimination (NAPRE) is a national program that strategizes the establishment of enzyme-linked immunosorbent assays (ELISA) to detect rabies antibodies.

Objective: We developed an in-house ELISA to screen for rabies antibodies using rabies vaccine antigen to study vaccine response among health care workers (HCWs) who received pre-exposure prophylaxis and a few animal bite victims who received post-exposure prophylaxis with rabies vaccine.

Article Synopsis
  • The study investigates the prevalence and impact of Human pegivirus-1 (HPgV-1) in Indian individuals living with HIV, as there is limited research on this topic.
  • Among 347 HIV treatment-naïve participants, 11% tested positive for HPgV-1, while only 1% of 100 healthy controls did; HPgV-1 genotype-2a was primarily found in those with HIV.
  • The research indicates a correlation between HPgV-1 viral load and CD4+ T-cell counts, hinting at HPgV-1's potential influence on HIV disease progression, though further longitudinal studies are necessary for a clearer understanding.

The nature of vaccine response inferiority is not well studied in children living with HIV (CLHIV). The authors investigated Hepatitis B Virus (HBV) and Diphtheria/Pertussis/Tetanus toxoid (DPT) vaccination responses following primary immunization in CLHIV (n = 42) and healthy controls (HC) (n = 38) and the effect of an additional vaccine dose. Antibody responses, CD4 and HBV-specific T/B cells were analysed using CMIA/ELISA and flow-cytometry.

Background: Monkeypox (Mpox) is an important human pathogen without etiological treatment. A viral-host interactome study may advance our understanding of molecular pathogenesis and lead to the discovery of suitable therapeutic targets.

Methods: GEO Expression datasets characterizing mRNA profile changes in different host responses to poxviruses were analyzed for shared pathway identification, and then, the Protein-protein interaction (PPI) maps were built.

Background: Human cytomegalovirus (HCMV) reactivation is a major cause of morbidity and mortality among stem cell transplant recipients post-transplantation.

Aim: HCMV immediate-early messenger RNA (IE-mRNA) was evaluated as marker of post-transplant HCMV reactivation in bone marrow transplant recipients.

Method: ology: An in-house real-time reverse transcriptase PCR targeting IE-mRNA was developed to estimate HCMV mRNA levels post-transplantation.
