Flocks1
Diseases1
- Live bird markets (LBMs) are essential for marketing of poultry, but can be a hub for the rapid spread of diseases including avian influenza (AI). (uncst.go.ug)
LPAI1
- However, LPAI is monitored because two strains of LPAI- the H5 and H7 strains-can mutate into highly pathogenic forms. (usgs.gov)
Respiratory tract2
- Signs/symptoms may include uncomplicated upper respiratory tract signs and symptoms also referred to as influenza-like illness (ILI) [fever ≥100°F plus cough or sore throat], fever (temperature of 100ºF [37.8ºC] or greater) or feeling feverish, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches, fatigue, eye redness (or conjunctivitis), shortness of breath or difficulty breathing. (cdc.gov)
- It is the only in vitro diagnostic test for influenza that is cleared by the FDA for use with lower respiratory tract specimens. (medscape.com)
Species1
- Her team is developing innovative culture methods for avian primary epithelial and endothelial cells to study the understanding of the host species-specificity of HPAIVs genesis. (erasmusmc.nl)
Clinical1
- The FDA waived federal Clinical Laboratories Improvement Act (CLIA) requirements and cleared for marketing seven rapid influenza diagnostic tests that directly detect influenza A or B virus-associated antigens or enzyme in throat swabs, nasal swabs, or nasal washes. (medscape.com)
Diagnosis1
- A laboratory diagnosis of influenza is established once specific cytopathic effect is observed or hemadsorption testing findings are positive. (medscape.com)
Laboratory2
- Findings of standard laboratory studies, such as a complete blood count (CBC) and electrolyte levels, are nonspecific but helpful in the workup of influenza. (medscape.com)
- Uruguayan authorities said the first case of a sea lion with avian influenza had been detected in the country after a specimen was found dead on the Cerro beach on Aug. 31 and the laboratory tests were announced Tuesday, it was reported in Montevideo. (flutrackers.com)

Neuraminidase inhibitors1
- Zanamivir and oseltamivir are members of a class of drugs termed neuraminidase inhibitors and are active against both influenza virus type A and type B. They are approved for both prophylaxis and treatment of influenza. (medscape.com)
