DNA restriction analysis was carried out on a sample of 73 adenovirus strains isolated in Buenos Aires from nasopharyngeal aspirates of children with lower acute respiratory infection between 1984 and 1988. Thirty-five isolates (47.9%) were classified as members of subgenus B. Of these, three were identified as a new genome type of Ad3p denominated Ad3p3; five strains corresponded to genome type 7b and two to genome type 7c. The other 25 isolates were identified as the recently recognized genome type 7h. All 6 fatalities recorded within this group of 73 children were associated with infection by Adenovirus genome type 7h. Thirty-seven isolates (50.7%) were classified within subgenus C that corresponded to 9 different genome types denominated 1p (n = 5); 1# (n = 2); 2p (n = 4); 2b (n = 6); 2# (n = 5); 5# (n = 4); 5* (n = 7) and 5+ (n = 2). All genome types of subgenus C were compared with the data reported by Adrian et al. (Archives of Virology 112:235-238, 1990). The Ad1p and Ad1# genome types could be allocated to AV1 genome types D1 and D10, respectively. Ad2b genome type could be allocated to AV2 genome type D25. No counterparts were found for the remaining 6 genomic variants. Only one isolate was identified as Ad4a of subgenus E. The comparison of the results of the present study with those of the molecular characterization of Chilean strains isolated between 1984 and 1987 suggests that the adenovirus strains associated with respiratory disease of children may be common in both countries.

Adenovirus 3 was found associated with ten cases of infantile lower acute respiratory infection in patients aged 2-18 months. Of these, five had a fatal outcome, with severe lung damage. Restriction enzyme analysis with Bam HI, Bcl I, Bgl II, Bst E II, Hind III, Sal I, Sma I, Xba I, and Xho I revealed the presence of the same genome type in all ten specimens. The genomic variant was different from those previously reported for serotype 3 and therefore was tentatively denominated 3f.

A total of 80 nasopharyngeal secretions collected from malagasy children (53 boys and 27 girls) with viral acute respiratory infection, aged from 6 days to 10 year old admitted to the Pediatric Department of Antananarivo General Hospital from may to July 1983, were investigated by indirect immunofluorescence method. 54--samples were found positive for respiratory viruses. Distribution according age groups and sex has been studied: children belonging to 25-36 month age group and male sex were more infected. Following viral strains were detected in increasing frequency: Para-influenzae 3: 25 p. 100; RSV: 18 p. 10/; Adenovirus: 18 p. 100; Influenzae A: 13 p. 100; Influenzae B: 9 p. 100; Para-influenzae 1: 5 p. 100.

Sixteen infants and toddlers from four kibbutz day nurseries contracted an illness comprising fever, conjunctivitis, respiratory infection, lymphadenopathy, otitis media, and a new sign, migratory palpebral erythema. Adenovirus type 3 was isolated from the pharynx of the first three children taken ill.

Enteropathogens were investigated in 406 children aged 0-3 years with diarrhoea attending the Salles Neto Municipal Hospital. Enteric bacterial pathogens were isolated from 49 per cent of the children. Enterotoxigenic Escherichia coli (ETEC) (20.9 per cent), enteropathogenic E. coli (EPEC) (16.5 per cent), rotavirus (11.6 per cent), and Campylobacter (9.9 per cent) were the most common agents. Among clinical features, vomiting and fever were significantly associated with Rotavirus isolation (50.0 per cent), respiratory infection with Adenovirus (14.3 per cent), bloody diarrhoea with Campylobacter (12.5 per cent), and dehydration with EPEC (71.6 per cent).

Viral laboratory diagnosis was correlated with clinical and epidemiological data from 80 hospitalized children with acute lower respiratory infection (ALRI). They all were less than 5 years-old and were studied from May to September 1993. Fifteen percent of them were malnourished and 75% had some unsatisfied basic necessity. Nasopharingeal aspirates were obtained the first day of hospitalization, and diagnosis for respiratory viruses was performed by the immunofluorescence test with monoclonal antibodies. Routine laboratory determinations, x-ray studies, and clinical data were not conclusive to determine viral etiology. Forty-one percent of the children had a positive viral diagnosis: the most important agent was Respiratory Syncytial Virus (78.7%) followed by Adenovirus (9.1%), Influenza A (6.1%) and Parainfluenza (3%). The peak of incidence was observed in June and the majority of the patients remained hospitalized less than 10 days. Six children died: two of them had viral pneumonia and could not receive mechanical respiratory assistance. The percentage of children who received antibiotics was high, 61.2%, in spite of the fact that 34.7% of these patients had a laboratory confirmed viral etiology. The availability of rapid laboratory viral diagnosis may contribute to decrease the use of antibiotics and improve the management of patients.

Adenovirus (ADV) is increasingly recognized as a cause of morbidity and mortality in transplant recipients, but ADV pneumonitis has rarely been reported after lung transplantation. The few reported instances of ADV pneumonitis occurred mostly in children immediately after lung transplantation suggesting "primary" infection. We report a fatal case of ADV pneumonitis occurring in an adult, 4 years after unilateral lung transplantation, in whom the premortem diagnosis was not determined. Autopsy revealed severe necrotizing bronchitis, bronchiolitis, and interstitial pneumonitis. Characteristic smudgy intranuclear inclusions, immunohistochemistry for viral protein, in situ hybridization for viral genome, and postmortem lung cultures established ADV as the etiologic agent. ADV can cause fatal, occult respiratory infection in adult lung transplant recipients, remote from transplant surgery.

An immunoglobulin G of mouse was purified from sera by affinity chromatography in protein A. The rabbits whose sera were able to recognize the antigen injected by double immunodiffusion were immunized with this preparation. The antibodies were precipitated from the rabbit's serum and purified by ion exchange chromatography. This preparation was conjugated to fluorescin isothiocyanate according to the conventional technique. The conjugated obtained was evaluated with the reference strains of Parainfluenza virus 1, 2, 3; Adenovirus; respiratory syncytial virus; and influenza virus A and B, by an indirect immunofluorescence technique and HIV positive samples by flow citometry. Specific monoclonal antibodies were used in both cases. Clinical specimens of patients with acute respiratory infection were evaluated.

Adenovirus are important pathogen primarily associated to respiratory infections of children and military personnel, even though it is also associated to cases of conjunctivitis and keratoconjunctivitis. We analyzed respiratory secretion collected from subjects with and without respiratory infection symptoms, being 181 civilians and 221 military subjects. The samples were inoculated in HEp-2 and/or A549 tissue cultures for viral isolation. Samples presenting cytopathogenic effect (CPE) in any tissue culture were tested by a polymerase chain reaction (PCR) assay to confirm adenovirus isolation. The isolates confirmed as adenovirus were further analyzed by restriction endonuclease assay for determination of viral species. Three isolates were identified as specie A (two from civilian and one from military), one isolate from military was identified as specie C, and one isolate from civilian was identified as specie D. For two isolates the specie could not be identified.

In April 2004, two patients were admitted to hospital in Berlin, Germany, with clinical signs of acute respiratory infection after returning from a military exercise in their home country of Turkey. They were admitted to a high security infectious disease unit as epidemiological data pointed to an outbreak of unknown etiology. Samples taken at the time of admission proved to be strongly positive for Adenovirus by PCR, but negative for Influenza A/H1N1 virus, Influenza A/H3N2 virus, Influenza B virus, Respiratory syncytial virus, and SARS coronavirus. No evidence for bacterial infection was obtained by serological tests and blood cultures. The adenovirus detected was characterized further by genotyping and was identified as a species B2 virus with the highest similarity to adenovirus type 11a.
