| biological transmission of arboviruses: reexamination of and new insights into components, mechanisms, and unique traits as well as their evolutionary trends. | among animal viruses, arboviruses are unique in that they depend on arthropod vectors for transmission. field research and laboratory investigations related to the three components of this unique mode of transmission, virus, vector, and vertebrate host, have produced an enormous amount of valuable information that may be found in numerous publications. however, despite many reviews on specific viruses, diseases, or interests, a systematic approach to organizing the available information on all f ... | 0 | 16223950 |
| a tropical menace of co-infection of japanese encephalitis and neurocysticercosis in two children. | japanese encephalitis (je) is a mosquito borne encephalitis caused by flavivirus. neurocysticercosis (ncc) is a parasitic disease of the central nervous system caused by taenia solium. in this report, we describe the clinical profile, imaging findings, and outcome of two children with je and coexisting ncc. eleven and thirteen-year-old boys from the same town of jharkhand state were brought with history of fever, seizures, altered sensorium, and extrapyramidal symptoms. dystonia, hypomimia, brad ... | 0 | 27606026 |
| climate change impacts on west nile virus transmission in a global context. | west nile virus (wnv), the most widely distributed virus of the encephalitic flaviviruses, is a vector-borne pathogen of global importance. the transmission cycle exists in rural and urban areas where the virus infects birds, humans, horses and other mammals. multiple factors impact the transmission and distribution of wnv, related to the dynamics and interactions between pathogen, vector, vertebrate hosts and environment. hence, among other drivers, weather conditions have direct and indirect i ... | 0 | 25688020 |

| epidemiological studies on japanese encephalitis in kyoto city area, japan. iii. seasonal prevalence of virus infections in several pig populations shown by virus recovery from engorged culex tritaeniorhynchus summorosus. | when vector mosquitoes engorged by feeding on pigs are tested for virus recovery after incubation for 7 to 10 days, the results may show mosquito infection itself. therefore, seasonal prevalence of infection in each pig population can be estimated from course of the infection rate among mosquitoes. many mosquitoes of the main vector of japanese encephalitis virus, culex tritaeniorhynchus summorosus, collected by light traps everyday or every other day in some pig sheds from 1967 to 1970 were tes ... | 1978 | 215807 |
| epidemiological studies on japanese encephalitis in kyoto city area, japan. iv. natural infection in sentinel pigs. | natural infection with japanese encephalitis virus in three sentinel pigs held in separate experimental huts was examined daily by virus recovery from blood samples of the pigs and from mosquitoes after incubation for about 7 days from their blood feeding and by hi antibody titration of the blood samples. after a period of low infection rates, below 6%, for about two weeks in engorged culex tritaeniorhynchus summorosus, high mosquito infections of over 30% from each viremic pig occurred for two ... | 1978 | 213633 |
| epidemiological studies on japanese encephalitis in kyoto city area, japan. ii. annual patterns of virus dissemination on virus recoveries from unfed culex tritaeniorhynchus summorosus. | annual patterns of dissemination of japanese encephalitis virus in vector mosquitoes have been investigated at the main collection station from 1965 through 1973 at some other stations from 1969 through 1971. the virus was recovered usually from culex tritaeniorhynchus summorosus during a period of about a month from july to august every year till 1969, and from august to september after 1970, although at some of the stations the virus was recovered intermittently for longer or shorter terms. hi ... | 1978 | 207914 |
| epidemiological studies on japanese encephalitis in kyoto city area, japan. i. evidence for decrease of vector mosquitoes. | mosquito collections by using light traps have been carried out at 10 to 11 stations in kyoto city area at intervals of about 10 days every year. mean percent indexes (mpi), being calculated from the data of mosquito collections, were used for comparison of the annual abundance of mosquitoes. it is no doubt that culex tritaeniorhynchus summorosus has decreased recently and this decrease is correlated with the reduction of human patients of japanese encephalitis. wide use of two herbicides, cnp a ... | 1978 | 207913 |

| japanese encephalitis virus in mosquito salivary glands. | culex tritaeniorhynchus and c. pipiens mosquitoes were infected with japanese encephalitis virus either by intrathoracic injection or by membrane feeding. the virus maturation sites and the process of virus particle concentration in salivary gland cells were studied by electron microscopy. occurrence of mature virions was primarily associated with intracytoplasmic viral matrices which were extraordinarily large and had a perinuclear location in c. pipiens mosquitoes. the other sign of virus repl ... | 1979 | 219722 |
| isolation of japanese encephalitis virus from the republic of the philippines. | a total of 33, 274 mosquitoes was collected from tagudin, ilocos sur province, philippines during july 1977. isolates made from one pool of culex tritaeniorhynchus and one pool of c. vishnui were identified as japanese encephalitis virus (jev) by a micro-neutralization test using reference hyperimmune mouse ascitic fluids. this is the first known isolation of jev from the philippines. | 1980 | 6108000 |
