Timing and source of subtype-C HIV-1 superinfection in the newly infected partner of Zambian couples with disparate viruses

Retrovirology, 2012
Background HIV-1 superinfection occurs at varying frequencies in different at risk populations. Though seroincidence is decreased, in the negative partner of HIV-discordant couples after joint testing and counseling in the Zambia Emory HIV Research ...

Characterisation of HIV superinfection : genetic evolution and adaptive immune responses [PDF]

, 2011
In this thesis we aimed to determine the timing and frequency of intra-subtype C superinfection, and to determine if the reason for superinfection was a greater genetic distance within epitopes of the superinfecting virus compared to those of circulating

Analysis of Synchronous and Asynchronous In Vitro Infections with Homologous Murine Norovirus Strains Reveals Time-Dependent Viral Interference Effects

Viruses, 2021
Viral recombination is a key mechanism in the evolution and diversity of noroviruses. In vivo, synchronous single-cell coinfection by multiple viruses, the ultimate prerequisite to viral recombination, is likely to be a rare event and delayed secondary ...

HIV-1 Superinfection Resembles Primary Infection [PDF]

, 2015
The relevance of superinfection as a model to identify corre-lates of protection against human immunodeficiency virus (HIV) depends on whether the superinfecting transmission resembles primary infection, which has not been established.

Transcriptional Profiling of Immune and Inflammatory Responses in the Context of SARS-CoV-2 Fungal Superinfection in a Human Airway Epithelial Model

Microorganisms, 2020
An increasing amount of evidence indicates a relatively high prevalence of superinfections associated with coronavirus disease 2019 (COVID-19), including invasive aspergillosis, but the underlying mechanisms remain to be characterized.

Rapid Detection of Bacterial and Fungal Pathogens Using the T2MR versus Blood Culture in Patients with Severe COVID-19

Microbiology Spectrum, 2022
A high rate of bacterial and fungal superinfections was reported in critically ill patients with COVID-19. However, diagnosis can be challenging. The aim of this study is to evaluate the sensitivity and the clinical utility of the point-of-care method T2

Comodulation of Dengue and Chikungunya Virus Infection During a Coinfection Scenario in Human Cell Lines

Frontiers in Cellular and Infection Microbiology, 2022
The Dengue virus (DENV) and Chikungunya virus (CHIKV) are the arboviruses that pose a threat to global public health. Coinfection and antibody-dependent enhancement are major areas of concern during DENV and CHIKV infections, which can alter the clinical
