Nine patients who seroconverted were identified, and 1 had PARV4 viremia (genotype 1) over an 8-month period. (cdc.gov)
We conclude that high levels of circulating CMV DNA in viremic AIDS and solid organ transplant patients reflect viral involvement of visceral organs but not the retina. (jci.org)
In the majority of patients infected with the European subtype of TBEV, CNS inflammation is preceded by a febrile illness, resulting in a biphasic course of the disease. (orpha.net)
Results: Ten patients were diagnosed with vascular malformations and 6 with vascular tumors. (bvsalud.org)
These studies show promising results and can help manage dengue patients, especially in resource-constrained settings in endemic zones, leading to better managing of dengue patients. (hilarispublisher.com)
Of 271 patients who had laboratory-confirmed IPD, 55 (20%) had a positive SARS-CoV-2 test result. (cdc.gov)

We describe the prevalence and correlates of CMV viraemia in HEU and HIV-unexposed-uninfected (HUU) infants, and quantify associations with anthropometric, haematological and immunological outcomes. (lstmed.ac.uk)

We are pleased with our collaborative relationship with Astellas, and we look forward to the results from the pivotal Phase 3 study in HCT recipients, which we expect to obtain during the fourth quarter of 2017," said Vijay Samant, President and Chief Executive Officer, Vical. (astellas.com)
Welcome to the Chimerix Conference Call discussing the financial results of the Fourth Quarter and Full-Year 2017. (seekingalpha.com)
This morning at 7:30 Eastern Time, we issued a press release containing financial results and other updates for the fourth quarter and full-year 2017. (seekingalpha.com)

This is not the case for infectious virions associated with MMR as they become bloodborne(viremia). (acsh.org)
The presence of viral mRNA in the blood with COVID differs from viremia, if is not infectious and offers no specific binding sites. (acsh.org)

however, there is increasing concern in how to interpret test results with low levels of viremia, particularly in the context of increasing exposure to antiretroviral treatment and prophylaxis. (columbia.edu)

The large fragment encodes the viral polymerase. (medscape.com)

Viremia is classified into types depending on how the virus infected the bloodstream. (medicalnewstoday.com)
An antigenic shift may result in a worldwide pandemic if the virus is efficiently transmitted from person to person. (cdc.gov)
PCR and compared the results with a standard curve generated from stock virus of known titer. (cdc.gov)
These results demonstrate, for the first time, that a single inoculation of an Ad5-interferon virus can be used as a tool to immediately control FMD in emergency outbreak situations. (usda.gov)
In parallel to the serological tests, it was carried out for molecular testing to detect viral RNA, applying a real-time PCR technique and using primers designed for a more conserved region of the virus (ORF-3). (usp.br)

Results -Neonatal calves inoculated with BVDV alone or with BVDV on day 1 and BRV on day 7 developed villus atrophy and submucosal inflammation of the intestines. (avma.org)

and examine factors associated with sustained viremia and mortality. (biomedcentral.com)
T-cell depletion techniques may result in reduced transplant-related mortality compared with unmanipulated grafts due to a lower incidence of GvHD. (bvsalud.org)

We reported PARV4 genotype 3 viremia in young children with unknown parenteral blood exposure from the rural Ashanti region of Ghana ( 7 ). (cdc.gov)
Blood donor data were compared with results from previous studies covering 2004-08. (eurosurveillance.org)
Pure Red Blood Cell Aplasia Acquired pure red blood cell aplasia is a disorder of erythroid precursors that results in an isolated normocytic anemia. (msdmanuals.com)

To facilitate cloning of non-induced proviruses we tested whether comparable levels of activation and viral outgrowth could be achieved in transwell cultures in which patient cells were separated from donor lymphoblasts by a cell-impermeable membrane (Figure S1B). (healthyguide.info)

A chest radiograph finding consistent with pneumonia and a bronchoalveolar lavage (BAL) result that is CMV positive is a common method for diagnosis. (medscape.com)
