diagnosis of japanese encephalitis


Introduction.

Japanese encephalitis can be prevented by vaccination. It has been shown that the E MAb produced by Yaoming Li according to the nucleotide sequence of E gene of JEV genotype III possessed sensitive reaction with prevalence-predominant JEV genotype I [10], which suggested that our ELISA assay could be applied to clinical detection of different JEV genotypes.

+258 (MZ) +960 (MV) Description The virus that causes Japanese encephalitis is called an arbovirus, which is an arthropod-borne virus. Rapid Diagnostic Tests (RDT): Confirmation of JE infection requires laboratory diagnosis such as virus isolation or detection of IgM in the patient�s serum or CSF. Specific binding between antibody and antigen is the most important factor for the successful development of ELISA assay. Additionally, the higher sensitivity with our capture ELISA for detecting JEV antigen than with traditional ELISA has been confirmed in our assay, it could be due to introducing of a horseradish peroxidase (HRP)-labeled goat anti-rabbit antibody for specifically identifying detection antibody, which has amplified the reaction signals in whole system and modified the sensitivity. statement and The perspective represented by this book, that of medical virology as an infectious disease science, is meant to provide a starting point, an anchor, for those who must relate the subject to clinical practice, public health practice, ... Birds are often the source of infection for mosquitoes, which can then spread the infection to horses and other animals. Initial symptoms often include fever, headache, and vomiting. The cross-reactivity between JEV and WNV was difficult to avoid because of the high homology of them. It is a mosquito-borne flavivirus, meaning it is related to dengue, yellow fever and West Nile viruses. +592 (GY) 2015 Dec 10;9(12):e0004074.

Mosquitoes in a number of regions carry this virus . Second, the ELISA assay has been confirmed with relatively high sensitivity. It usually occurs in rural or agricultural areas, often . Causes of encephalitis include viruses such as herpes simplex virus and rabies as well . Since the ineluctability of false positive reaction by RT-PCR and the low sensitivity of ICS always prevent the applying of these methods for accurate diagnosis of JEV, our ELISA assay may be developed as an alternative method for fast diagnosis of JEV infection.
