Immune histories and natural infection protection during the omicron era
(
Springer Nature
, 2025 , Article)
Background: Past immunological events can either enhance or compromise an individual's future immune protection. This study investigated how different severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) natural ...
Insects in agricultural greenhouses: a metagenomic analysis of microbes in Trialeurodes vaporariorum infesting tomato and cucumber crops
(
Frontiers Media SA
, 2025 , Article)
Introduction: With the predicted 9-10 billion world population increase by 2050 and its accompanying need for sustainable food production, and with the harsh climate conditions challenging agriculture and food security in ...
Seroprevalence of influenza A H1N1 and influenza D viruses in ruminants in Qatar
(
Elsevier
, 2025 , Article)
BackgroundInfluenza is among the most common viruses affecting humans and many animals worldwide. While influenza A (IAV) and D (IDV) viruses are associated with respiratory disease in humans and animals, respectively, ...
Evaluating Hospital Admission Data as Indicators of COVID-19 Severity: A National Assessment in Qatar.
(
Oxford University Press
, 2025 , Article)
Accurately assessing SARS-CoV-2 infection severity is essential for understanding the health impact of the infection and evaluating the effectiveness of interventions. This study investigated whether SARS-CoV-2-associated ...
Evaluating chemiluminescent immunoassays for syphilis detection: A comparative analysis
(
Elsevier
, 2025 , Article)
BackgroundSyphilis, caused by Treponema pallidum (TP), remains a significant global public health concern, with approximately 8 million new cases annually. Diagnosing syphilis is challenging due to its often-asymptomatic ...
Protection conferred by SARS-CoV-2 infection across a spectrum of reinfection symptoms and severities
(
BMJ Publishing Group
, 2025 , Article)
Background SARS-CoV-2 infection is associated with protection against reinfection. This study analysed this protection across different reinfection symptoms and severities, comparing the preomicron and omicron eras. Methods ...
Comprehensive analysis of human coronavirus antibody responses in ICU and non-ICU COVID-19 patients reveals IgG3 against SARS-CoV-2 spike protein as a key biomarker of disease severity
(
Microbiology Society
, 2025 , Article)
Introduction. Pre-existing immunity to human coronaviruses (HCoVs) may shape the immune response in COVID-19 patients. Increasing evidence suggests that immune cross-reactivity between SARS-CoV-2 and other coronaviruses ...
Antibody-dependent enhancement of SARS-CoV-2, the impact of variants and vaccination
(
Taylor and Francis Group
, 2025 , Article)
This study characterized antibody-dependent enhancement (ADE) in serum samples from individuals exposed to SARS-CoV-2 via infection or vaccination and evaluated its association with SARS-CoV-2 variants (Wuhan and Omicron), ...
The impact of pre-existing immunity on the emergence of within-host immune-escape mutations in Omicron lineages
(
Microbiology Society
, 2025 , Article)
The Omicron variant of SARS-CoV-2 circulating amongst highly immunized populations is anticipated to induce immunological pressures, potentially compromising existing immunity. This study investigates vaccine-induced ...
Diet-induced mechanical stress promotes immune and metabolic alterations in the Drosophila melanogaster digestive tract
(
Elsevier
, 2025 , Article)
A fundamental query in immunology is how cells recognize danger in the tissue milieu. For many years, standpoints were mainly centered around damaged cells or structures of invading pathogens, like lipopolysaccharide, being ...
