| pharyngoconjunctival fever caused by adenovirus type 4: report of a swimming pool-related outbreak with recovery of virus from pool water. | during the summer of 1977, an outbreak of pharyngoconjunctival fever (pcf) occurred at a private recreational facility in georgia. a total of 72 cases of pcf was identified. adenovirus type 4 (av-4) was recovered from conjunctival or pharyngeal swab specimens from 20 of 26 persons in the group of cases tested. av-4 was also recovered, for the first time reported in the literature, from two concentrated samples of water obtained from the swimming pool at the facility on different dates. all perso ... | 1979 | 222852 |
| [virusenteritis in childhood (author's transl)]. | about 20% of infantile enteritis are caused by bacterial infections. the most cases of non bacterial infantile enteritis are supposed to be viral infections. arguments for the existence of enterotropic viruses arised the first time in 1943. since the middle of the fifties, various kinds of enteroviruses are known to be causative agents of infantile gastroenteritis. the same is true occasionally for some types of adenovirus. in 1973 the norwalk-agent was discovered provocing enteritis mainly in a ... | 1979 | 222939 |
| interferon induction by adenoviruses. | all human, simian, bovine and avian adenovirus types tested so far and the canine hepatitis virus induce interferon production in chick cells. this finding indicated this property to be characteristic for viruses belonging to the adenovirus group. trypsin treatment, which had no effect upon the infectivity, diminished or eliminated the interferon-inducing abilities of crude adenoviruses, and thus the need for a trypsin-sensitive protein in interferon induction was suggested. t antigen and interf ... | 1979 | 223139 |
| some aspects of the role of viruses in cancer. | the cells of tumours induced by many oncogenic dna viruses, or cells transformed in vitro, contain virus-specific t and transplantation antigens; these have been described for sv40 virus, polyoma virus and adenoviruses. the investigation of viruses as causes of malignant disease in man has sought to establish whether tumour cells possess these virus-specific proteins; however, to date and with the limitations of present techniques, this enquiry has not demonstrated the above viruses as causal of ... | 1979 | 223141 |
