The pathogenesis of respiratory syncytial virus infection in cotton rats. 1978

G A Prince, and A B Jenson, and R L Horswood, and E Camargo, and R M Chanock

The cotton rat is susceptible to respiratory synctial virus infection in both the upper and lower portions of the respiratory tract. Virus replicates to high titer in the nose and lungs and to relatively low titer in the trachea. Immunofluorescence studies demonstrated viral antigen in the nasal epithelium and the bronchial and bronchiolar epithelium but not in the trachea or the alveolar cells of the lungs. Histopathologic changes included a desquamative, exudative rhinitis of moderate severity and a mild proliferative bronchiolitis. Serum neutralizing antibody developed in all animals by the ninth day after infection, reaching extremely high titer in several instances. Unlike the previously described response of experimentally infected infant ferrets, cotton rats are uniformly susceptible to pulmonary infection throughout life, thereby offering a model for long-term pulmonary studies heretofore not available.

UI	MeSH Term	Description	Entries
D008168	Lung	Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood.	Lungs
D009500	Neutralization Tests	The measurement of infection-blocking titer of ANTISERA by testing a series of dilutions for a given virus-antiserum interaction end-point, which is generally the dilution at which tissue cultures inoculated with the serum-virus mixtures demonstrate cytopathology (CPE) or the dilution at which 50% of test animals injected with serum-virus mixtures show infectivity (ID50) or die (LD50).

D010253	Respirovirus Infections	Infections with viruses of the genus RESPIROVIRUS, family PARAMYXOVIRIDAE. Host cell infection occurs by adsorption, via HEMAGGLUTININ, to the cell surface.	Infections, Respirovirus
D012136	Respiratory Syncytial Viruses	A group of viruses in the PNEUMOVIRUS genus causing respiratory infections in various mammals.

D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
