Representative type strains as well as field strains of Pasteurella multocida from fowl cholera were examined by the indirect hemagglutination procedure and by a rapid plate agglutination test. The former method identified the specific capsular or K substance, and the latter identified the somatic antigens. Inagglutinable organisms were made agglutinable for the rapid procedure by treatment wit...

Immunity to adenoviruses is an important hurdle to be overcome for successful gene therapy. The presence of antibodies to the capsid proteins prevents efficacious adenovirus vector administration in vivo. We tested whether immunity to a particular serotype of adenovirus (Ad5) may be overcome with a vector that encodes the hexon sequences from a different adenovirus serotype (Ad12). We successfu...

From January to December 1998, nasopharyngeal aspirates were obtained from 482 children with acute respiratory infections attended in emergence department and wards of a teaching hospital in the city of Salvador, Brazil. The samples were tested for the presence of adenovirus by isolation in tissue culture and indirect immunofluorescence assay. Eleven adenoviruses were detected by both methods i...

The prevalence of Adenovirus was determined among children with gastroenteritis/ diarrhea in Warri, Southern, Nigeria. Adenovirus was detected using a lateral flow immunochromatographic test kit (Gastro Vir-Strip, Coris Bioconcept, Belgium). The prevalence of Adenovirus was 11 (14.7%) and there were no association with age and gender of subjects. There is need for routine screening of Adenoviru...

Adenoviral vectors can be used to generate potent humoral and cellular immune responses to transgene products. Use of adenoviral vectors based on non-human isolates may allow for their utilization in populations harbouring neutralizing antibodies to common human serotypes. A vector chimera was constructed using simian adenovirus 22 (a serotype belonging to the species Human adenovirus E) and si...

Until now, the only published ovine adenovirus DNA sequence was the complete genome of ovine adenovirus isolate 287 (OAV287) which, compared to other mammalian adenoviruses, possesses strikingly unique genomic organisation and should properly be classified into a new adenovirus genus. The protease gene sequence of ovine adenovirus type 3 (OAdV-3) was determined and analysed. The results of phyl...
