In a test area (suburbs of Nouméa), a survey on acute infantile gastro-enteritis showed an annual incidence of 2.2% and a hospitalization rate of 27.5%. The 0 to 23 months age group was the most exposed. The factors of severity were: a low age, a high frequency of liquid stool, vomits, fever and associated acute respiratory infection. The etiologic(More)
Enterotoxigenic Escherichia coli (ETEC) of infant origin from the Popular Democratic Republic Lao were characterized with respect to there 0 serogroups, biotypes, anti-bioresistances, fimbrial antigens and types of enterotoxins produced. Enterotoxin production was determined by the suckling mice assay, competitive GM1-erythroassay, and cell cultures (CHOK1(More)
After an outbreak in 1956, poliomyelitis appears to get a sporadic development. Consequently, it has not been a major medical concern. In 1982, 5 cases of paralytic manifestations due to a polio virus of type 1 underlined the relationship between this reappearance of the disease, some neglecting in mass vaccination and some deficiency in sanitary conditions(More)
Eight viral isolates were recovered from Eidolon helvum bats collected in Nigeria and Cameroon in 1971 and from the Central African Republic in 1974. Subsequent studies showed that the agents from the three countries were similar and were strains of a new virus of the Orbivirus genus, family Reoviridae. This new virus was characterized with respect to its(More)
During an outbreak of arboviral diseases in the South-West Pacific islands, from 1979 to 1980, patients sera examined in New Caledonia revealed 43 cases of epidemic polyarthritis due to Ross River virus. Viral strains were obtained from 16 of these patients. After isolation of the virus in newborn mice, the inoculation of C6/36, PS-EK and Vero cells allowed(More)
During an outbreak occuring in Futuna (Horne Islands) from October 1976 to January 1977, II strains quite similar to dengue virus type I were isolated from blood of patients in acute phase. Immunitary responses were noted on 8/12 paired sera submitted to IH test; 4/17 serum samples showed antibody titer presumptive of a recent infection. Entomological(More)
From 1975, epidemiological studies on arboviral diseases, conducted in New Caledonia, Vanuatu, Wallis and Horne Islands, have shown that 11 species of mosquitoes may harbour viruses in natural conditions. Virus isolations were attempted from 1,025 pools of Culicidae totalizing 32,182 individuals belonging to 5 genera and 21 species. Viral infections have(More)
