Symptomatic plant viroid infections in phytopathogenic fungi [PDF]

Proceedings of the National Academy of Sciences, 2019
Significance Viroids are the only known autonomously replicating pathogenic agents that do not encode proteins. As viroids are known only to naturally infect plants, their infectivity and pathogenicity in other eukaryotes are largely unexplored.

Norovirus Infection and Disease in an Ecuadorian Birth Cohort: Association of Certain Norovirus Genotypes With Host FUT2 Secretor Status. [PDF]

, 2015
BACKGROUND: Although norovirus is the most common cause of gastroenteritis, there are few data on the community incidence of infection/disease or the patterns of acquired immunity or innate resistance to norovirus.

Diagnostic Performance of Ag-RDTs and NAAT for SARS-CoV2 Identification in Symptomatic Patients in Catalonia

Viruses, 2021
The use of rapid antigenic tests (Ag-RDTs) to diagnose a SARS-CoV-2 infection has become a common practice recently. This study aimed to evaluate performance of Abbott PanbioTM Ag-RDTs with regard to nucleic acid amplification testing (NAAT) in the early

Shedding of norovirus in symptomatic and asymptomatic infections

Epidemiology and Infection, 2014
SUMMARYNorovirus is the most frequent cause of acute infectious gastroenteritis and it is difficult to control in crowded environments like hospitals and nursing homes. Transmission depends on oral intake of virus deposited in the environment by infectious subjects.

An age-of-infection model with both symptomatic and asymptomatic infections

Journal of Mathematical Biology, 2023
We formulate a general age-of-infection epidemic model with two pathways: the symptomatic infections and the asymptomatic infections. We then calculate the basic reproduction number $\mathcal{R}_0$ and establish the final size relation. It is shown that the ratio of accumulated counts of symptomatic patients and asymptomatic patients is determined by ...

Murine cytomegalovirus genomic material in marrow cells; relation to altered leukocyte counts during sublethal infection of mice [PDF]

, 1987
To investigate infection of hematopoietic cells by murine cytomegalovirus (MCMV), we used in situ hybridization to detect MCMV genomic material in marrow cells during sublethal infection of three-week-old mice.

Gene Signatures of Symptomatic and Asymptomatic Clinical-Immunological Profiles of Human Infection by Leishmania (L.) chagasi in Amazonian Brazil

Microorganisms, 2023
Individuals infected with Leishmania (L.) chagasi may present different asymptomatic and symptomatic stages of infection, which vary in the clinical–immunological profiles that can be classified as asymptomatic infection (AI), subclinical resistant ...
