  View All» Qty/Pk: 2 mL View All» Product Overview: Intended Use Light Diagnostics™ SimulFluor® Para 1, 2, 3/ Adeno Immunofluorescence Assay is intended for the simultaneous detection of parainfluenza 1, 2, and 3 and adenovirus following amplification in cell culture. For In Vitro Diagnostic Use. Summary and Explanation Respiratory viruses are responsible for a significant proportion of illness in human populations. Some viruses (e.g. influenza) are seasonal while others (e.g. adenovirus) predominantly affect different age groups. In a given population, respiratory viruses may be responsible for a considerable amount of morbidity. The advent of appropriate anti-viral therapy against some respiratory viruses makes rapid screening to identify these organisms imperative, allowing early institution of therapy. The two most widely used anti-viral agents today are amantadine/rimantadine for influenza A and ribavirin for respiratory syncytial virus bronchiolitis. Both agents have varying modes of action although most involve early infection steps such as penetration or uncoating (12,19). At physiologically attainable concentrations, amantadine and rimantadine specifically inhibit replication of influenza A (4). Ribavirin has broad spectrum activity in vitro against a host of viruses such as respiratory syncytial virus, measles, influenza A and B, and parainfluenza (7,13,14). Parainfluenza viruses, combined with respiratory syncytial virus, represent the most significant upper respiratory pathogens in infants and young children (1,2,3,5). Four types of parainfluenza virus have been identified in children and adults. Types 1 and 2 are major causes of laryngotracheo-bronchitis (croup). The severity of illness is greatest in children ages 2 to 4 years (6). Parainfluenza type 3 infection can also lead to croup and is second only to respiratory syncytial virus as a cause of infant bronchiolitis and pneumonia (8,9,10,11,15). Illness from type 3 infection is most severe in infants less than 1 year old (6). In older children and adults, illness may be asymptomatic or mimic the common cold (16). Severe croup in early childhood or infancy may result in bronchial hyperactivity in older children or adolescents after exercise. However, it remains undetermined whether bronchial hyperactivity was a pre-existing condition, which played a role in the pathogenesis of croup, or whether it developed as a complication of severe croup illness (17,18). Parainfluenza type 4 has been associated only with mild upper respiratory illness in adults and children and is difficult to identify in cell culture (6). Parainfluenza viruses belong to the genus Paramyxovirus of the family Paramyxoviridae. They are enveloped viruses with a single-strand RNA genome of negative polarity and range in diameter from 150 to 200 nm (20). Parainfluenza viruses grow well in primary simian or human kidney cell lines and in LLC-¬MK2, a rhesus kidney heteroploid cell line (21). Trypsin is needed in the medium for the recovery of types 1 and 2, but not 3. Virus infection of tissue culture can be recognized by hemadsorption of guinea pig erythrocytes. Types 2 and 3 can be recognized by syncytium formation. Human adenoviruses belong to the family Adenoviridae, genus Mastadenovirus. They are icosahedral, non-enveloped, double stranded DNA viruses 70 90 nm in diameter (23). They have a protein coat of 240 hexon and 12 penton capsomeres. Adenoviruses are responsible for a significant number of clinical respiratory illnesses, particularly in children. Upper respiratory diseases in infants and young children can include colds, pharyngitis, and tonsillitis, while lower respiratory illnesses include bronchitis and bronchiolitis (23), and approximately 10% of childhood pneumonia (24). In children under 5, adenovirus is responsible for about 5% of cases of acute respiratory disease (ARD), which is manifested by nasal congestion, coryza, cough and, at times, tonsillitis, fever, and myalgia. The appearance of conjunctivitis with ARD constitutes pharyngoconjunctival fever. In addition to respiratory infections, adenoviruses can be a cause of other significant illnesses. Ocular disease resulting from adenovirus infection include epidemic keratoconjunctivitis (EKC), acute hemorrhagic conjunctivitis, and acute follicular conjunctivitis. In addition, adenovirus is related to several gastrointestinal disorders and is probably evident in 7 17% of all childhood gastroenteritis. Types 40 and 41 have been associated with diarrhea and acute gastroenteritis (25). Adenovirus has also been linked with intussusception (26), acute hemorrhagic cystitis (27), and meningoencephalitis. Research indicates that the incidence of adenovirus infection in immuno-compromised patients is probably no higher than in normal individuals; however, the severity and probability of death may be greater (28). With the exception of types 40 and 41 which grow only in Graham 293 cells, adenovirus can be cultured and isolated in a variety of cell lines such as HEp 2, A549, KB, and HEK. Infection is usually confirmed by immunofluorescence or enzyme immunoassay (EIA). Typical adenovirus cytopathic effects (CPE) manifest as grape-like clusters of rounded, refractive cells with intranuclear inclusions, which appear in 3 to 10 days post-infection (29). Viruses can be identified in patient specimens and by culture isolation/ confirmation. Light Diagnostics™ SimulFluor® Para 1, 2, 3/ Adeno Immunofluorescence Assay utilizes monoclonal antibodies to simultaneously detect parainfluenza 1, 2 and 3, and identify adenovirus following amplification in culture. Adenovirus can also be detected and identified in direct patient specimens. Test Principle Light Diagnostics™ SimulFluor® Para 1, 2, 3/ Adeno Immunofluorescence Assay utilizes a single reagent for the simultaneous detection of parainfluenza 1, 2 and 3, and identification of adenovirus. The SimulFluor® Para 1, 2, 3/ Adeno Reagent contains two components. The primary component is directed against parainfluenza 1, 2 and 3; the second component is specifically directed against adenovirus. The monoclonal antibodies in the components will bind to the appropriate viral antigen on the specimen slide. Unbound antibody is washed from the slide with phosphate buffered saline (PBS). Parainfluenza 1, 2 and 3-infected cells will exhibit an apple-green fluorescence; while, adenovirus-infected cells will exhibit a yellow-gold fluorescence. The primary component staining the parainfluenza 1, 2 and 3-infected cells bright apple-green does not differentiate between these viruses. The secondary component staining the adenovirus-infected cells bright yellow-gold allows for the differentiation of adenovirus from parainfluenza 1, 2 and 3 in a single well. Uninfected cells stain dull red due to the presence of Evans blue counterstain in the reagent. View All» Key Applications: Immunofluorescence View All» Usage Statement:
