| antigenic characterization of intermediate adenovirus 14-11 strains associated with upper respiratory illness in a military camp. | an unusual variant of adenovirus (av) 11 was isolated from throat and rectal swabs from six persons with upper respiratory illness in a spanish military camp in march 1969. the same strain was serologically related to the upper respiratory illness of seven other men among 25 sample cases studied in detail. after strain purification, the virus was grouped as an av by standard biological tests; it possessed the usual titers of group-specific hexon antigen but only low hemagglutinin titers (1:4 to ... | 1976 | 177365 |
| electron microscope study of experimental enteric adenovirus infection in mice. | using fluorescent antibody techniques (fa) and light microscopy (lm) and electron microscopy (em), this paper describes the morphological features of the ileum in the dk1 mouse orally challenged with adenovirus k87. at the peak of infection, virus is easily identified by fa in the epithelium of the villi and crypts of the ileum. lm shows that fluorescent cells have large, bizarre, uniformly basophilic nuclei containing deoxyribonucleic acid, as indicated by histochemical tests. em further identi ... | 1976 | 177370 |
| coxsackievirus and adenovirus infection. association with acute febrile and juvenile rheumatoid arthritis. | the prearthritic manifestations of juvenile rheumatoid arthritis in a 16-year-old boy were associated with a rise in coxsackievirus b3 and a9 neutralizing antibody titers from 1:16 to larger than or equal to 1:512, and 1:64 to 1:512, respectively. recurrent polyarthritis followed and has persisted for three years. adenovirus 7 was isolated from the pericardial fluid of a 9-year-old girl in whom juvenile rheumatoid arthritis then developed. of 11 patients with acute, nonspecific, febrile arthriti ... | 1976 | 177792 |
