development of a nano-elisa system for the rapid and sensitive detection of h9n2 avian influenza
Authors
abstract
influenza is one of the most important viral diseases that is common among the birds and the mammalsand is caused by specific viruses that belong to the orthomyxoviridae family. migratory aquatic birds arethe reservoir of the disease and there is a likelihood of the disease in any region. there are differentmethods for detecting the avian influenza, but by the point of detection rates, the elisa may be one ofthe most important current methods. in this work we synthesized gold nanoparticles and conjugated itwith rabbit-anti-chicken igg-hrp. an elisa test was done to compare the bioactivity of au-antichickenhrp with anti-chicken hrp in order to detect the antibody against the h9n2 subtype of avianinfluenza virus. using 133 field chicken sera, the sensitivity of nano-elisa as compared to traditionalelisa was calculated to be 100%, whereas the specificity was 92%. this method was significantly moresensitive than the traditional elisa and didn’t require extra costs. it can therefore be concluded that theaunp-hrp conjugate can be applicable in immune analysis procedure where a more confident result isrequired.

full textAssessment of a rapid immunochromatographic assay for the detection of avian influenza viruses
Rapid spreading of the low pathogenic avian influenza virus (AIV) caused by the H9N2 subtype and the highly pathogenic AIV caused by H5N1 have caused serious economic losses in the poultry industries of Asia. Therefore, the early detection of AIVs is crucial for the control of the disease. In the present study, the applicability of a rapid immunochromatographic (RIC) assay, which specifically d...
full textPerformance of rapid tests for detection of avian influenza A virus types H5N1 and H9N2.
Among the avian influenza A virus subtypes, the H5N1 and H9N2 viruses have the potential to cause an influenza pandemic because they are widely prevalent in avian species in Asia and have demonstrated the ability to infect humans (8). Currently, human infections with wild-type (wt) strains of these viruses could occur in the United States in poultry and turkey farm workers and in travelers retu...

An experimental inactivated oil-emulsion H9N2 avian influenza vaccine was formulated with 3 parts ofinactivated avian influenza antigen A/Chicken/Iran/101/1998(H9N2) emulsified in 7 parts of oil adjuvant.Twelve week-old specific pathogen-free (SPF) chickens were divided into seven groups of 10 birds. Sixgroups were vaccinated with 1, 1/10th, 1/50th, 1/100th, 1/200th and 1/400th field dose of th...
