Viral Diseases 2013-11-17 .txt text/plain 15852 898 46 The number of viruses known to be naturally infectious for laboratory rats is small, and most cause inapparent infections which usually are detected by serological monitoring (Table I) . Significance: Latent, vertically-transmissible agent isolated from submaxillary gland; no signs or lesions; induces HAI antibody; unre lated antigenically to rat coronaviruses or cytomegalovirus; must dif ferentiate isolates from coronaviruses, cytomegaloviruses C. Infected rats excrete virus from the respiratory tract for about 7 days, at which time anti-SDAV antibody is first detectable in serum by either NT or CF tests ( Fig. 30 and Table V) (61) . Infections of SDAV or RCV can be diagnosed on the basis of clinical signs, lesions, and serological profiles of NT and CF antibody and confirmed by isolation of the causative virus. The pathogenesis and lesions of natural and experimental Sendai virus infection have been well described for mice (2, 132, 160) , but only limited information on rats is available. ./cache/cord-022305-uvor9rts.txt ./txt/cord-022305-uvor9rts.txt
