A rapid and affordable point of care test for antibodies against SARS-CoV-2 based on hemagglutination and artificial intelligence interpretation

Scientific Reports, 2021
Diagnostic tests that detect antibodies (AB) against SARS-CoV-2 for evaluation of seroprevalence and guidance of health care measures are important tools for managing the COVID-19 pandemic. Current tests have certain limitations with regard to turnaround

Application of a ddRT-PCR to quantify seasonal influenza virus for viral isolation

Biosafety and Health, 2022
Viral isolation in cell cultures has been regarded for decades as the “gold standard” for the laboratory diagnosis of influenza viral infections. Not all viral strains could be isolated from clinical samples.

Evaluation of a Hemagglutination Test for Human Leptospirosis [PDF]

Applied Microbiology, 1973
An indirect hemagglutination test for the diagnosis of leptospirosis is described; the test uses a soluble antigen from serotype patoc to sensitize sheep erythrocytes which are then fixed with glutaraldehyde. Evaluation of this procedure indicates that it is more reliable than the conventional macroscopic agglutination test and, in contrast with both ...

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Safety of and serological response to a new canine distemper‐parvovirus combination vaccine in domestic ferrets

Veterinary Record, EarlyView.
Abstract Background Pet ferrets are typically vaccinated against distemper using a canine multivalent vaccine despite the lack of relevant safety or efficacy data. Here, we investigate the safety of a novel live canine parvovirus type 2c (CPV‐2c) vaccine strain and the efficacy of the live Onderstepoort canine distemper virus (CDV) vaccine strain used ...
