Monoclonal antibody (MAb) preparations specific for the enteric adenoviruses of subgenus F (AdF) were generated and evaluated as typing reagents in virus neutralization tests and enzyme-linked immunosorbent assays (ELISAs). A panel of 11 genome types of adenovirus 40 (Ad40), 24 genome types of Ad41, and 47 adenovirus prototype strains was used to determine the specificities of the MAbs in the t...

The DNA of 48 strains of adenovirus type 40 (Ad40) and of 128 strains of adenovirus type 41 (Ad41), isolated between 1971 and 1986 from various countries, was characterized by restriction enzyme analysis using nine and ten restriction endonucleases respectively. Five new DNA variants of Ad40 and 18 new DNA variants of Ad41 were detected. Most of the restriction sites which differed among the va...

Enteric adenovirus type 40 (Ad40) and Ad41 form the sixth subgenus of human adenoviruses. They are associated with infantile diarrhea but cannot be isolated in conventional cell cultures. The genome of the fastidious enteric Ad41 has been cloned, and the cleavage sites of the genome produced by restriction endonucleases BamHI, EcoRI, HpaI, NruI, PvuI, and SalI have been mapped. To develop usefu...

N-Trifluoroacetyladriamycin-14-valerate (AD32) and N-trifluoroacetyladriamycin (AD41) have been compared with Adriamycin and daunorubicin in CCRF-CEM human lymphoblastic cells. All four agents produce DNA damage, as measured by alkaline unwinding methods. Thymidine incorporation, a measure of DNA synthesis, is inhibited by AD32 and AD41 and completely blocked by the other drugs. AD32 and AD41 i...

EcoRI fragments B and C of the human enteric adenovirus type 41 strain TAK DNA(l) were cloned, sheared by sonication and rmbcloned in M13mpl8 vector. A 1315bp piece was assembled from sequences obtained from both strands by the Sanger method(2). This sequence contains the 3' end of the 33K phosphoprotein and the complete sequence of pVHI (hexon-assotiatedprecursor). Bases 1-231 overlap with the...

BACKGROUND Enteric adenoviruses 40 (Ad40) and adenovirus 41 (Ad41) have been shown to be a significant cause of paediatric gastroenteritis worldwide, but no data are available for nosocomial diarrhea due to adenovirus in Iran. AIM The present study was performed to determine the incidence of Ad40 and Ad41 in children less than five years with nosocomial diarrhea in Shahrekord, southwest Iran....

Genetic and antigenic characterizations of 70 strains of adenovirus type 41 (Ad41), isolated between 1998 and 2001 from children in Japan, Vietnam, and Korea, were done by DNA restriction enzyme (RE) analysis, sequencing analysis, and monoclonal antibody (MAb)-based enzyme-linked immunosorbent assay (ELISA). Eight genome types were observed in the present study, among which D25, D26, D27, and D...

During the period 1981 to 1992, 4,473 fecal specimens collected from children hospitalized with acute gastroenteritis at the Royal Children's Hospital, Melbourne, Australia, were examined by electron microscopy. A monoclonal antibody enzyme immunoassay for enteric adenovirus (EAd) types 40 (Ad40) and 41 (Ad41) was used when adenoviruses were visualized. Fecal samples were positive for adenoviru...

DNA sequencing of the human enteric adenovirus type 41 Tak position 83.1% to the AccI site at map position 87 .1%. Bases (1) genome upstream from the fiber protein gene (2) revealed 1161 to 1402 overlap the sequence published earlier by us (2). an open reading frame of 387 amino acids coding for a 41.4K protein. The first 42 amino acids of this protein show a high RFFERENCES degree of homology ...

Human enteric adenoviruses of species F contain two fibers in the same virion, a long fiber which binds to coxsackievirus and adenovirus receptor (CAR) and a short fiber of unknown function. We have determined the high-resolution crystal structure of the short fiber head of human adenovirus serotype 41 (Ad41). The short fiber head has the characteristic fold of other known fiber heads but has t...
