Abstract
Human adenoviruses (HAdVs) cause severe inflammatory respiratory infections, but previous epidemiological studies lacked analysis of the characteristics of the inflammation. Consecutive patients <13 years old with acute febrile illness during a 2‐year period were tested. HAdV strains were isolated from nasopharyngeal swabs, and molecular identification was performed by hexon, fiber, and species‐specific PCR methods. Blood inflammatory markers, including the white blood cell (WBC) count, CRP, and 29 cytokines, were measured. A total of 187 patients were enrolled, and HAdV types were identified from 175 patients (93.5%). Species C (types 2, 1, 5, and 6, in order of frequency) was most common at 37.1%, followed by B (type 3) at 30.9% and E (type 4) at 26.9%. Species C was detected predominantly in 1‐year‐old, whereas B and E were in older ages. Species C and B had seasonal circulation patterns, but E was found in only one season during the 2‐year study period. The WBC count was highest in patients with species C. Eleven of the 29 tested serum cytokines were detected. Seven kinds, including G‐CSF, IL‐6, and TNF‐α, were elevated in species C infections, whereas IL‐10 was lowest in species C. Species differences in inflammatory responses, especially regarding serum cytokines were described in common pediatric HAdV infections. Species C causes the strongest inflammatory responses in young children.

Abstract
Genome type analysis of adenovirus type 3 (Ad3) in Taiwan identified four types (Ad3a, Ad3a2, Ad3a1, Ad3-7) during 1983-2005. Ad3a was the major type during 1983-1999, while Ad3a2 was the predominant type from 2001 to 2005. Phylogenetic analysis of the hexon gene of 23 isolates revealed that most Ad3a2 and Ad3-7 isolates belonged to one cluster, and most Ad3a isolates to the other cluster. The clinical manifestations included respiratory tract infections, acute gastroenteritis, hand-foot-and-mouth disease, febrile convulsion and pharyngoconjunctival fever. In conclusion, Ad3a2 has replaced Ad3a as the most common genome type in Taiwan since 2001.

Abstract
A collection of 92 epidemiologically unrelated isolates of Ad1 (n = 14), Ad2 (n = 29), Ad3 (n = 19), Ad5 (n = 16), and Ad7 (n = 14) collected in the cities of Belem do Pará (1 degree S 48 degrees W) and Rio de Janeiro (23 degrees S 43 degrees W) between 1976 and 1995 from patients with respiratory disease and conjunctivitis were characterized by restriction enzyme analysis of genomic DNA. Among the strains of subgenus B, two different genome types of serotype 7, 7b and 7e, were identified. The analysis of their temporal distribution throughout the study period suggested an alternating appearance of these two DNA variants. Only one genome type of Ad3, 3p, was detected during the sampling period. Further analysis with Xba I, Bcl I, and Hpa I indicated that it is a p1-like genome type. Both previously described and new genomic variants were identified among subgenus C strains. Genome types D1, D7, D10, and one not previously described were identified among the 14 Ad1 strains analyzed. Genome types D2, D5, D25, and 13 new DNA variants were identified among the 29 Ad2 isolates. Genome type D38 and 5 new variants were found among the 16 strains of Ad5. In spite of the relatively small size of the sample analyzed, the results of this study confirm the important genetic variability previously observed for members of subgenus C by other authors.

Abstract
A collection of 165 adenovirus strains isolated from nasopharyngeal aspirates of children hospitalized for acute lower respiratory infection in Argentina, Chile, and Uruguay between 1991 and 1994 was studied by restriction enzyme analysis (work performed in the Department of Virology, University of Umeå). Of the isolates, 71% (n = 117) were identified as members of subgenus B. Of these, 101 (61.2%) corresponded to genome type 7h, four (2.4%) to genome type 3p2, four (2.4%) to genome type 11a, one (0.6%) to genome type 7b, and one (0.6%) to genome type 7c. Two isolates that were neutralized as serotype 3 and four isolates that were neutralized as serotype 7 exhibited novel BamHI cleavage profiles corresponding to three new genome types denominated 3x, 7i, and 7j. Subgenus C members represented 28.5% of all typed isolates. Five different genome types of Ad1, seven genome types of Ad2, and three genome types of Ad5 were identified of, which two, two, and one, respectively, were found to correspond to new DNA variants. Only one isolate (0.6%) corresponded to Ad4 of subgenus E. Ad7h was isolated from 17 of the 18 fatal cases recorded among the patients included in the study.

Abstract
In a prospective one-year study of acute gastroenteritis in hospitalized children less than 2 years of age, in São Paulo (Brazil), adenoviruses were detected by specific enzyme immunoassay (El-ARA) in 7 of 67 (10%) ill children and in 9 of 79 (11.4%) controls. They were the sole recognizable agent of diarrhea in 6 ill children. In another child these viruses were detected in a dual infection with astrovirus. Enteric adenoviruses (Ad40/41) were the most common serotypes detected in children with diarrhea (3/7) and Ad7 the serotype most detected in the controls (5/9), associated with lower respiratory tract infection. Thirteen adenovirus strains, isolated in HEp2 or HEK-293 cells, were characterized by seroneutralization and restriction enzyme analysis. The established adenoviruses were typed as AV-7-D5 (five associated to lower respiratory tract infection and one to diarrhea), AV-1-D10 (one diarrhea case), AV-31-D2 (two controls with respiratory infection), and two isolates as AV-12-D7, a new genome type. One subgenus D isolate, serotype 28, with restriction patterns different from those of the prototype, remained untyped. Only one enteric adenovirus could be typed. The restriction patterns of this isolated were similar to those of the prototype AV-41-D1. The genome type of the other three enteric adenoviruses could not be determined.

Abstract
Adenoviruses recovered from the northern Stockholm area during 1987-1992 have been subjected to restriction endonuclease analysis. Adenoviruses of all subgenera (A-F) were represented and a considerable degree of serotype variation was seen, e.g. the rarely encountered subgenus A viruses were frequently isolated in the present study. Of 16 subgenus A isolates, Ad31 predominated with 12 strains which were equally distributed into the DNA-variants D2 and D7. Analysis of 38 Ad3 isolates revealed four DNA-variants: D1, D3, D10, and "Sto1". The ten Ad7 isolates belonged all to the DNA-variant D5 of Ad7. Of 27 Ad1 strains, 11 belonged to D10, followed by the DNA-variants D4 and D7 with four strains each. Among Ad2 isolates, D2 or D2-like strains prevailed (23/28). Of six Ad5 strains, three belonged to the DNA-variant D2. The most notable subgenus D event was a nosocomial outbreak of keratokonjunctivitis due ot Ad19a. In addition, a collection of heterogenous subgenus D strains was detected, most of which untypable by RE-analysis. Among the six Ad4 isolates of subgenus E, both genomic clusters (p and a, respectively) of Ad4 were recognized. Concerning the clinical important subgenus F adenoviruses, only two strains of Ad40 were detected as compared to 12 strains of Ad41, all of which ascribed to the DNA-variant D12 of Ad41.

Abstract
Five hundred eighty-seven adenovirus type 3 (Ad3) isolates were established from children with acute respiratory infections (ARI) from 1986 to 1991, in Yamagata, Japan. Ad3 could be found in almost all the months during the 6 years when two epidemics occurred, in 1987 and 1989. A molecular epidemiological study was done on 346 of the 587 isolates, using restriction endonucleases; BamHI, HindIII, SmaI, and BgIII were used. The Ad3 isolates were classified into seven genome types. The genetic differences among the seven genome types were < 0.9%, and their phylogenetic tree, estimated by the neighbor-joining method, correlated highly with their monthly distribution. One genome type predominated for 56 months, while the other six related genome types cocirculated for a short period. These results suggested that the predominant genome type of Ad3 might have been endemically perpetuated in the Yamagata area with minor genomic variations. Furthermore, the outbreaks of Ad3 may have been due not to the appearance of a new genome type but rather to the endemic genome type.

Abstract
In a study designed to evaluate the genetic variability of adenovirus strains associated with infantile cases of respiratory disease requiring hospitalization, a collection of 136 adenovirus isolates obtained in the Roberto del Rio Children's Hospital of Santiago, Chile between June 1988 and November 1990 was studied by restriction enzyme analysis. Nasopharyngeal aspirates were obtained on admission from children under 2 years. During the study period a total of 227 adenovirus respiratory infections (ARI) were diagnosed at the ward for ARI by immunofluorescence, representing 23% of all admissions. Fifty percent of the 136 typed strains were found to belong to subgenus B, and the other 50% corresponded to subgenus C. Digestion with a set of seven enzymes allowed the identification of nine different genome types of subgenus C, three of which had not been previously described, exhibiting novel restriction patterns with either BgI II or BstEII. Ad7h, identified in 66 isolates, was the predominant genome type and was associated with the nine cases requiring mechanical respiratory assistance and with the two fatalities recorded during the 29 months. No differences were found between the age and sex distribution of subgenus B and C genomic variants, but the mean length of hospital stay (X +/- 2 SE) recorded among patients infected with subgenus B types was significantly higher (17.72 + 4.52 days (n = 55) vs. 7.54 + 1.70 days (n = 53); F = 17.22; P < 0.0001).

Abstract
All human adenoviruses isolated in Iceland during 1988-1990 have been subjected to restriction endonuclease analysis. Of 55 isolates altogether, subgenus C (Ad1, Ad2, and Ad5) predominated with 42 isolates followed by subgenus B (Ad3 and Ad7) with 12. Analysis of the 9 Ad1 isolates revealed 6 DNA-variants. Among these the established DNA-variants D4, D7, and D10 were recognized. The remaining 3 DNA-variants were primarily found in Iceland. Among the 22 Ad2 isolates, 7 DNA-variants could be distinguished. D2 predominated with 15 isolates whereas the prototype was isolated only once. The novel 5 DNA-variants of Ad2 were all closely related to D2. Analysis of the 11 Ad5 isolates revealed 6 DNA-variants, 2 of which (D2 and D5) were already established. Ice2 and D3 were the most common occurring DNA-variants of Ad5. Ad5 showed the highest degree of genomic variability within subgenus C, both in terms of the low degree of pair-wise comigration of restriction fragments and the number of principal variants of RE-patterns. Analysis of the 9 Ad3 isolates revealed 3 DNA-variants: D3, D10, and Ice1 (a novel DNA-variant that resembles D10). The DNA-variants D3 and D10 were each represented by 4 isolates. The three Ad7 isolates belonged all to the DNA-variant D5.

Abstract
A collection of 148 adenovirus strains of subgenus C collected in Argentina, Chile, and Uruguay were studied by restriction enzyme analysis of genomic DNA with endonucleases BamHI, BglII, BstEII, EcoRI, HindIII, KpnI, and SmaI. Only strains corresponding to serotypes 1, 2, and 5 were identified representing both already described and new genome types. The most frequently detected type was Ad 2 followed by Ad 1 and Ad 5. Three different genomic variants of both Ad 1 and Ad 5 were discriminated. Ad 2 with 9 genome types exhibited the greatest variability. Novel profiles emerged only in strains corresponding to this serotype by restriction with BglII and BstEII. The circulation of prototype-like strains of Ad 1 throughout the study period is note-worthy. Thirty-six of 43 strains corresponded to genome type D 1. Clearly, one genome type of each serotype predominated over the 7-year period (Ad 1 D 1, n = 36; Ad 2 D 5, n = 32, Ad 5 D 36, n = 17). Some genomic variants were detected sporadically and only in Argentina, Chile, or Uruguay whereas others were widely distributed and circulated for years. A high proportion of the analysed strains was isolated from children under one year and males were more frequently infected than females.

Abstract
We propose to classify "genome types" of human adenoviruses in the same way as the "genomic clusters" defined by Li and Wadell, i.e. groups of closely related DNA variants of a given serotype named by the use of indices, P (standing for prototype) a, b etc. Variants within the genome type are named by letter-number indices (p1, p2; a1, a2 etc.). The percentage of comigrating restriction fragments and common restriction sites is significantly higher in variants than between genome types. The new naming system is applicable to adenoviruses from 5 subgenera, but requires additional work for subgenus C strains. Renaming is required mainly for adenovirus 7.

Abstract
Adenovirus (AV) types 1, 2, and 5, isolated from about 480 patients from 1960 to 1985, most from the United States and Central Europe, were studied by DNA restriction analysis with the endonucleases BamHI, BglII, BstEII, EcoRI, HindIII, KpnI, and SmaI and compared with the respective prototypes. All different fragment patterns are presented as schematic drawings and their distribution on the genome types was analyzed. Prototype-like strains were isolated in all three types. AV2 exceeded AV1 and AV5 in its genetic variability. Among the many genome types found (36, 61, and 35 for AV1, 2, and 5 respectively), only one or few of each type prevailed, whereas many others were found only once. The temporal and geographic distribution of the genome types is presented.
