“…However, four new variants were observed in 1992. In 1990, a nationwide epidemiological surveillance of infectious conjunctivitis in Japan detected only one genotype, Ad3f, in 45 isolates of Ad3 [Shiao et al, 1996]. In contrast to the finding of only one genotype of Ad3, Ad3f, in 1990, it is notable that we have identified the emergence of four new genotypes in 8 of 55 Ad3 isolates in this study, from patients with acute conjunctivitis only 2 years after the former investigation.…”

“…Li et al [1996] found that Ad3a2 was predominant in children with pneumonia over a 27year period in China, except in 1984 when Ad3a4 was the most prevalent genotype. In contrast, Guo et al [1988] and Shiao et al [1996] identified solely Ad3f in patients with conjunctivitis in 1986and 1990, respectively. Itakura et al [1990 also reported that Ad3f predominated (84%) in conjunctivitis in 1986 in Japan.…”

“…In the present study, the aim was the detection of the chronological changing of genotype of Ad3 in Japan. Restriction endonuclease analysis using four enzymes was sufficient to compare the isolates with the strains reported previously, because in Japan, these four enzymes (BamH I, Bgl II, Hind III, and Sma I) have been used to detect changing genotypes of Ad3 [Guo et al, 1988;Itakura et al, 1990;Mizuta et al, 1994;Shiao et al, 1996]. Each new genotype was identified as a change in one restriction enzyme and their digestion patterns with the other three enzymes were the same as that for Ad3f.…”

“…Therefore, we have demonstrated that these isolates are new genotypes. The letters h, i, j, and k were assigned to each new genotype following our paper [Shiao et al, 1996]. This nomenclature is convenient for following the major changing trend of genotype of Ad3 in Japan.…”

“…The Ad3 genotype recovered from most conjunctivitis cases in Japan in 1983 was Ad3g [Guo et al, 1988]; however, this changed to Ad3f in 1986 [Itakura et al, 1990]. In 1990, all 45 isolates of Ad3 in Japan from patients with acute conjunctivitis were Ad3f [Shiao et al, 1996]. No Ad3g was detected in the same year.…”

Four new genotypes of adenovirus type 3 isolated from patients with conjunctivitis in Japan

et al. 1999

Adenovirus type 3 (Ad3) was the most frequently isolated serotype from patients with conjunctivitis during the period from 1989 to 1991 in Japan. All Ad3 strains isolated in 1990 had an identical genotype, Ad3f. However, in 1992, the predominant serotype was replaced by Ad4. The genome type was examined to determine whether genetic changes existed in Ad3 isolates in 1992. Ad3 isolated from 55 patients with acute conjunctivitis during the period from June 1992 to February 1993 in Japan was assessed by genome typing with restriction endonucleases BamH I, Bgl II, Hind III, and Sma I recognizing 6-base-pair sequences. The emergence of four new genotypes of Ad3 was identified; one with a new Bam HI site (one isolate), one with a new Bgl II site (two isolates), one with a new Hind III site (three isolates) and one with a new Sma I site (two isolates). This study demonstrates that the emergence of a new genotype of Ad3 may contribute to the replacement of the predominant serotype associated with adenovirus conjunctivitis in Japan.

Twelve strains of adenovirus serotype 19, isolated from cases of epidemic keratoconjunctivitis in Japan in 1992, 1993, 1997, and 1998, were analyzed by DNA restriction analysis, using restriction endonucleases BamHI, BglI, BglII, EcoRI, HindIII, KpnI, PstI, SacI, SalI, SmaI, and XhoI. Among these 11 restriction endonucleases, EcoRI, PstI, SacI, and SmaI were discriminative enzymes, showing restriction patterns different from those reported previously for the prototype and the variant 19a. This new genome type was isolated in 1997 and 1998, when an increase of epidemic keratoconjunctivitis cases caused by adenovirus serotype 19 was observed for both sporadic and nosocomial infections. Strains from 1992 and 1993 showed restriction patterns similar to those of the worldwide reported variant 19a for all enzymes used. The changes detected in strains from 1997 and 1998 could be the reason for the recent epidemic.

In a study of acute respiratory disease, two collections of nasopharyngeal aspirates (NPA) were obtained from children hospitalized at the Pediatric Clinic of the University Hospital, São Paulo, in 1995 and 2000. Adenovirus was detected in 33 (8.2%) of 401 children followed. These viruses were isolated in HEp-2, HEK-293, or NCI-H292 cells and serotyped by neutralization. The genome types were determined after restriction analyses of the genomic DNA extracted from infected cells. Nineteen isolates were characterized as Human adenovirus B, genome types HAdV-3a, HAdV-7h, and HAdV-7h1; 11 as Human adenovirus C, genome types HAdV-1D10, HAdV-2D25, HAdV-5D2, and HAdV-6D3. Our findings show that species C adenoviruses present an endemic infection pattern, with co-circulation of different serotypes and genome types; no new genomic variant was observed. Species B adenoviruses showed epidemic infection patterns, with shifts in the predominant genome type. The isolates from 1995 belong to genome type 7h, or the variant 7h1, with a clear substitution of the type 7b, prevalent in São Paulo for more then 10 years. In 2000, the variant 7h1 predominated and the emergence of the type 3a was observed. Almost 10 years passed between the identification of HAdV-7h in Argentina and its detection in São Paulo. The geographic isolation of these two countries was reduced by the increase in population mobility due to growing commercial relationships.
