identification by dna hybridization of enterotoxigenic escherichia coli in a longitudinal study of villages in thailand. | radioactively labeled enterotoxin genes were used to study the epidemiology of enterotoxigenic escherichia coli infections in two thai villages. when e. coli that were isolated from 674 specimens were fixed on nitrocellulose paper and examined for hybridization with e. coli enterotoxin gene probes in bangkok, the technique had a sensitivity of 94% (31 of 33) and a specificity of 100% (641 of 641), when compared with tests of e. coli for enterotoxin production in the y-1-adrenal cell and suckling ... | 1985 | 3880798 |
cholera-like illness due to aeromonas sobria. | a thai woman from bangkok was admitted to a hospital in paris for a cholera-like illness. a culture of her "rice-water" diarrhea was negative for vibrio cholerae and enterotoxigenic escherichia coli but was positive for aeromonas sobria. this strain produced enterotoxin, cytolysin, proteolysin, hemolysin, and a cell-rounding factor. acute -and convalescent-phase sera showed an increase in neutralizing antibodies to enterotoxin, cytolysin, and hemolysin. the enterotoxin, which was labile at 100 c ... | 1982 | 7054327 |
new initiatives for the control of japanese encephalitis by vaccination: minutes of a who/cvi meeting, bangkok, thailand, 13-15 october 1998. | japanese encephalitis (je) is a leading cause of viral encephalitis in asia that, in several countries, has been controlled effectively through national vaccine programs. however, in recent years, transmission has been recognized or has intensified in new locations where the available vaccines are either unaffordable or unlicensed. in addition, the near-eradication of poliomyelitis from asia has elevated je in the public health agenda of preventable childhood diseases, and surveillance of acute ... | 2000 | 10821969 |
prevalence of antibodies to leptospira serovars in rodents and shrews trapped in low and high endemic areas in thailand. | to investigate the prevalence of antibodies to leptospira serovars in rodents and shrews trapped in urban and rural areas in low and high endemic areas in thailand. | 2003 | 12678151 |
seroprevalence of rickettsial infection in commensal rodents and shrews trapped in the bangkok metropolitan area. | murine typhus and scrub typhus are important human rickettsial diseases in thailand. small mammals, including many species of rodents and shrews, serve as the reservoir host of rickettsial diseases. rickettsia typhi can be transmitted to humans by fleas causing murine typhus, while infection with orientia tsutsugamushi causing scrub typhus in humans is transmitted by chiggers. the prevalence of rickettsial infection depends on the geographic area. the seroprevalence of antibody to r. typhi and o ... | 2003 | 12924799 |
surveillance of commensal rat and shrew populations in the bangkok area with references to flea index as the risk indicator of plague. | commensal rats and shrews were trapped from 47 fresh food markets in bangkok during the two study periods in the same markets: 21st june to 28th december 1999 and 1st march to 31st may 2000. trapping was performed using wire live traps on three consecutive nights in each period. the trapped animals were identified for taxonomic species and flea infestation. fleas were collected, identified and counted. four species of rodents: rattus norvegicus, rattus rattus, rattus exulans and mus musculus, an ... | 2003 | 14649963 |
prevalence of rabies virus and hantaan virus infections in commensal rodents and shrews trapped in bangkok. | five hundred rodents and shrews (rattus norvegicus: 458, rattus rattus: 28, rattus exulans: 5, mus musculus: 4 and suncus murine: 5) trapped from the fresh food markets around bangkok area were investigated for rabies virus and hantaan virus infections. no rabies viral antigens in the animals' brains were detected by direct immunofluorescence. on the other hand, antibodies to hantaan virus were demonstrated in the sera of 7 (1.53%) r. norvegicus caught in various markets using a particle aggluti ... | 2003 | 14696782 |
