background and aims: celery mosaic virus (cemv) is one of the causal agents of viral diseases in celery (apium graveolens). cemv is a member of the potyvirus genus in potyviridae family. the virus is naturally transmitted by aphids in a non-persistent manner. during growing season 2006-2007 viral disease symptoms were observed in celery fields grown in tehran province (bage daneshkade, mohamads...

Rheumatoid factor became the first laboratory marker of rheumatoid arthritis and one serological markers used to recognize major autoimmune diseases. Details discovery with special regard contribution E. Waaler H. Rose are presented in this historical review. Same assays exam factor, its frequency modern view on diagnostic significance different diseases described article.

Invasive fungal infections (IFI) are a significant cause of morbidity and mortality in the immunocompromised. The traditional diagnostic methods of culture and histological examination lack sensitivity and often only make a diagnosis late when the fungal burden is high, reducing the chances of cure even with the availability of new more potent and less toxic antifungal agents. New non-culture-b...

Reliable serological tests are required to determine the prevalence of antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and characterize immunity disease in order address key knowledge gaps 2019 (COVID-19) pandemic. Quantitative suspension array technology (qSAT) assays based on xMAP Luminex platform overcome limitations rapid diagnostic enzyme-linked immunosorben...

Transposition of diagnostic tests used in domestic livestock species to free-ranging and captive wildlife species has two problems. First, most existing tests have not been adequately validated in domestic livestock. Second, assumptions that a serological test will perform identically in wildlife and livestock species may not be correct, due to differences in pathogenic strains and serovars, ho...

BACKGROUND: Sporadic outbreaks of bovine trypanosomiasis have been reported in Bolivia since 1996 when T. vivax and T. evansi were identified for the first time by parasitological means. However, comprehensive epidemiological information concerning T. vivax and T. evansi in the country is lacking. Current parasitological and serological diagnostic methods for trypanosomiasis have important limi...

<b><i>Objective:</i></b> To assess the diagnostic performance of lateral flow immunochromatographic assays (LFAs) 4 different manufacturers to identify SARS-CoV-2 antibodies (IgM, IgG, or total), comparing them with nucleic acid amplification test (NAAT) clinical defined (definite probable infection, respectively). <b><i>Methods:</i></b> One hundr...

West Nile Fever is a zoonotic disease caused by a mosquito-borne flavivirus, WNV. By its clinical sensitivity to the disease, the horse is a useful sentinel of infection. Because of the virus' low-level, short-term viraemia in horses, the primary tools used to diagnose WNV are serological tests. Inter-laboratory proficiency tests (ILPTs) were held in 2010 and 2013 to evaluate WNV serological di...
