Serological evidence of SARS-CoV-2 infection in dromedary camels and domestic bovids in Oman
Emerging Microbes and Infections, 2023 SARS-CoV-2 has demonstrated the ability to infect a wide range of animal species. Here, we investigated SARS-CoV-2 infection in livestock species in Oman and provided serological evidence of SARS-CoV-2 infection in cattle, sheep, goats, and dromedary ...

Viruses, 2023 Background Sotrovimab, a monoclonal antibody against SARS-CoV-2, is used as a pre-exposition prophylaxis (PrEP) against COVID-19, but monitoring strategies using routine test systems have not been defined.

Allele excess at neutrally evolving microsatellites and the implications for tests of neutrality [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2004 Skews in the observed allele-frequency spectrum are frequently viewed as an indication of non-neutral evolution. Recent surveys of microsatellite variability have used an excess of alleles as a statistical approach to infer positive selection. Using neutral coalescent simulations we demonstrate that the mean numbers of alleles expected under the ...

A single, continuous metric to define tiered serum neutralization potency against HIV
eLife, 2018 HIV-1 Envelope (Env) variants are grouped into tiers by their neutralization-sensitivity phenotype. This helped to recognize that tier 1 neutralization responses can be elicited readily, but do not protect against new infections.

Clinical Utility of SARS-CoV-2 Serological Testing and Defining a Correlate of Protection
Vaccines, 2023 Herein, we review established clinical use cases for SARS-CoV-2 antibody measures, which include diagnosis of recent prior infection, isolating high titer convalescent plasma, diagnosing multisystem inflammatory syndrome in children (MIS-C), and booster ...

Testing for Neutrality in Samples With Sequencing Errors [PDF]
Genetics, 2008 AbstractMany data sets one could use for population genetics contain artifactual sites, i.e., sequencing errors. Here, we first explore the impact of such errors on several common summary statistics, assuming that sequencing errors are mostly singletons. We thus show that in the presence of those errors, estimators of θ can be strongly biased.

Journal of Venomous Animals and Toxins including Tropical Diseases, 2009 We examined the ability of IgG anti-crotalic PLA2 to cross-react with Bothrops spp. venoms, from snakes found in the northeast of Argentina. Immunoblotting and ELISA tests showed that IgG anti-crotalic PLA2 recognize antigens of bothropic venoms ...

Sensitive neutralization test for rubella antibody [PDF]
Journal of Clinical Microbiology, 1979 A modified rubella virus plaque neutralization test for measuring rubella antibody was developed based on the potentiation of the virus-antibody complex by heterologous anti-immunoglobulin. The test is highly sensitive, yielding titers on the average 50 to 100 times higher than the haemagglutination inhibition test or the conventional plaque ...

Kinetics of Serologic Responses to MERS Coronavirus Infection in Humans, South Korea
Emerging Infectious Diseases, 2015 We investigated the kinetics of serologic responses to Middle East respiratory syndrome coronavirus (MERS-CoV) infection by using virus neutralization and MERS-CoV S1 IgG ELISA tests.

Microbiology Spectrum, 2023 Neutralizing antibodies (nAbs) are considered a valuable marker for measuring humoral immunity against SARS-CoV-2. However, live-virus neutralization tests (NTs) require high-biosafety-level laboratories and are time-consuming. Therefore, surrogate virus
