Nucleic acid sequence-based amplification assays for rapid detection of West Nile and St. Louis encephalitis viruses.

Assays for Rapid Detection of West Nile Nucleic Acid Sequence-Based Amplification

Evaluation of Nucleic Acid Sequence Based Amplification (NASBA) and Reverse Transcription Polymerase Chain Reaction for Detection of Coxsackievirus B3 in Cell Culture and Animal Tissue Samples

Enteroviruses are the causative agents of a number of diseases in humans. Group B coxsackieviruses are believed to be the most common viral agents responsible for human heart disease. Genomic data of enteroviruses has allowed developing new molecular approaches such as Nucleic Acid Sequence Based Amplification (NASBA) for detection of such viruses. In this study, coxsackievirus B3 (CVB3) was de...

Noninfectious recombinant antigen for detection of St. Louis encephalitis virus-specific antibodies in serum by enzyme-linked immunosorbent assay.

Proper surveillance of virus activity and a timely response to viral outbreaks depend upon the rapid diagnosis of viral infections. The immunoglobulin M (IgM) antibody-capture enzyme-linked immunosorbent assay (MAC-ELISA) is a fast, sensitive test routinely used for the diagnosis of the medically important West Nile and St. Louis encephalitis flaviviruses. However, the suckling mouse brain-deri...

Surveillance for Western Equine Encephalitis, St. Louis Encephalitis, and West Nile Viruses Using Reverse Transcription Loop-Mediated Isothermal Amplification

Collection of mosquitoes and testing for vector-borne viruses is a key surveillance activity that directly influences the vector control efforts of public health agencies, including determining when and where to apply insecticides. Vector control districts in California routinely monitor for three human pathogenic viruses including West Nile virus (WNV), Western equine encephalitis virus (WEEV)...

Rapid identification of dengue virus by reverse transcription-polymerase chain reaction using field-deployable instrumentation.

Dengue virus universal and dengue serotype 1 to 4, fluorogenic probe hydrolysis (TaqMan), reverse transcription-polymerase chain reaction assays were developed for screening and serotype identification of infected mosquito vectors and human sera using a field-deployable, fluorometric thermocycler. Dengue universal and dengue 1 to 4 serotype assay in vitro sensitivity and specificity results wer...
