| japanese encephalitis in sri lanka--the study of an epidemic: vector incrimination, porcine infection and human disease. | a prospective study of mosquito vectors, porcine infection and human disease was carried out during a japanese encephalitis (je) epidemic in the north central province of sri lanka (november-december 1987) and a subsequent non-epidemic year (1988). the epidemic involved 361 cases of human encephalitis, virologically confirmed by immunoglobulin m enzyme-linked immunosorbent assay (elisa), and was preceded 2-3 weeks earlier by sentinel porcine seroconversion. virus isolation and viral antigen dete ... | 1992 | 1329275 |
| survey of adult mosquitoes (diptera: culicidae) during irrigation development in the mahaweli project, sri lanka. | a survey of adult mosquitoes was done during 1986-1987 in an area undergoing irrigation development in the mahaweli project of sri lanka. the study encompassed two 12-mo phases of settlement and irrigation, respectively. diurnal human bait catches yielded 1,427 female mosquitoes in 27 species. nocturnal collections (human bait, cdc light traps, indoor resting catches) produced a total of 30,491 females in 67 species. comparisons with an earlier survey in the predevelopment forest showed that the ... | 1991 | 1678784 |
| viruses isolated from mosquitoes collected in sri lanka. | attempts to isolate viruses from 178,181 unengorged female mosquitoes collected from different ecologic areas of sri lanka yielded 31 isolates: 17 of japanese encephalitis (je) virus, nine of getah virus, three of a batai-related bunyavirus, and two of arkonam virus. culex tritaeniorhynchus and mansonia uniformis mosquitoes were found to carry je virus in a dry zone nonepidemic area, and cx. pseudovishnui was found to carry it in a wet zone nonepidemic area. japanese encephalitis virus was isola ... | 1994 | 7915499 |
| human dirofilariasis caused by dirofilaria (nochtiella) repens in sri lanka. | human dirofilariasis due to dirofilaria (nochtiella) repens is a common zoonotic infection in sri lanka. todate 70 cases are on record, and they include 3 expatriates from russia, england and korea, who were undoubtedly infected in sri lanka. around 30-60% of dogs are infected with d. repens in various parts of the country and the mosquito vectors are aedes aegypti, armigeres subalbatus, mansonia uniformis and m. annulifera. unlike in other countries of the old world infection is most common in ... | 1997 | 9802095 |
| filarial diseases in ceylon: a geographic and historical analysis. | medical records concerning filarial diseases in ceylon date from the account of davy[1], though there are hints as to the more obvious manifestations in the old chronicles of the country, too. a first survey was conducted in 1912/1913 concentrating on urban areas, followed by a second survey in the 1930s with emphasis on the rural parts. the results displayed a remarkable distribution pattern: wuchereria bancrofti, the so-called "urban type", concentrated in galle and matara towns, whereas brugi ... | 1983 | 6152421 |
| larval survey of surface water-breeding mosquitoes during irrigation development in the mahaweli project, sri lanka. | a survey of ground water-breeding mosquitoes was done during 1986-1987 in an area undergoing irrigation development in the mahaweli project of sri lanka. forty-nine species were collected during the 12-mo phase of humans settlement and infrastructure construction, and 42 species during the succeeding 12-mo period under irrigated rice culture. development resulted in the elimination of some preexisting breeding habitats, the modification of others, and the creation of new habits. the overall chan ... | 1990 | 1977912 |
| [virus manombo (mg ar 966), a provisionally new arbovirus isolated from culicidae in madagascar]. | in april 1987, a virus strain was isolated from a pool of mansonia uniformis caught on human bait, in a tropical primary rain forest area of the south-east coast of madagascar. antigenically, this virus may not be related to other known viruses, and constitutes a provisionally new arbovirus called virus manombo. | 1991 | 1688286 |
