| a comparison of type o foot and mouth disease virus field isolates from northern thailand. | a survey of type o foot and mouth disease (fmd) virus isolates from northern thailand was undertaken to determine the relationship between field viruses and the vaccine in use, and to gauge the range of antigenic variation among field viruses. isolates were collected from the two most recent epizootics, 1986-1987 and 1989-1990, and assessed using a two-dimensional neutralisation test to determine their relationship to fmd type o1 bangkok 1960 (o bkk/60) reference (vaccine challenge) virus. the c ... | 1992 | 1335305 |
| serological comparison of type asia 1 foot and mouth disease virus isolates from thailand. | antigenic variation of type asia 1 foot and mouth disease (fmd) virus in thailand was examined using a total of 50 field viruses isolated between 1986 and 1992. a two-dimensional serum neutralisation test was used to calculate r values for comparison of these isolates with a reference vaccine strain, asia 1 bangkok 1960 (bkk/60). viruses were also compared to two field isolates, asia 1 36-2/88 and asia 1 45/88, and some were compared to another vaccine strain, asia 1 nakhon pathom 1984 (npt/84). ... | 1995 | 8593388 |
| serological comparison of type a foot and mouth disease virus isolates from thailand. | antigenic variation of type a foot and mouth disease (fmd) virus in thailand was examined using a total of 82 field viruses isolated between 1986 and 1989. a two-dimensional serum microneutralisation test was used to compare these isolates to a reference strain, a15 bangkok 1960 (a bkk/60). viruses regarded as unrelated to a bkk/60 were compared to another reference strain, a22 nakhon pathom 1986 (a npt/86). this approach divided the viruses into two groups. most of the viruses shared a close an ... | 1995 | 8593389 |
| epidemiology and characterization of leptospirosis at an urban and provincial site in thailand. | patients with fuos at the children's hospital in bangkok and the chao phya abhai bhu bejhr hospital in prachinburi were screened for leptospirosis by blood and urine culture in addition to microagglutination testing of their serum. animal populations in urban and periurban areas of bangkok were surveyed for evidence of leptospira infection. three rural sites near the prachinburi provincial hospital were also surveyed. the rodents' and domestic animals' blood, urine, and/or kidney cell samples we ... | 1988 | 3227409 |
| a longitudinal study of japanese encephalitis in suburban bangkok, thailand. | a one-year study of japanese encephalitis (je) in a small focus of transmission was conducted in suburban bangkok in 1985. monthly data were collected on weather, vector density, sentinel pig and chick je antibody seroconversions, and epidemiology as related to human je cases. the primary vector species were found to be culex gelidus and culex tritaeniorhynchus; from which one isolate each was obtained in march and june, respectively. pig je antibody seroconversion peaked in april (the hottest m ... | 1987 | 2896391 |
| japanese encephalitis virus in bangkok: factors influencing vector infections in three suburban communities. | an unexpected outbreak of japanese encephalitis (je) in bangkok in 1985 led us to investigate the vector ecology of urban je from january 1986 to june 1987 at three suburban sites that displayed a wide range of factors imputed to influence je transmission. culex tritaeniorhynchus giles and cx. gelidus theobald, suspected vectors, comprised 71-96% of all mosquitoes collected by co2-baited cdc traps at the three sites. mean of mosquito abundance per two trap-nights per month ranged from 28 to 5,72 ... | 1992 | 1320699 |
| clinical presentations of pandemic 2009 influenza a (h1n1) virus infection in hospitalized thai children. | a novel influenza a (h1n1) virus of swine origin caused human infection and acute respiratory illness in mexico during the spring of 2009. after that, the virus spread globally, resulting in the influenza pandemic. | 2011 | 22043762 |
| risk factors and epidemiology of the ten most common salmonella serovars from patients in thailand: 2002-2007. | we conducted a retrospective observational study to assess epidemiological trends and risk factors associated with the 10 most common salmonella serovars isolated from humans in thailand between 2002 and 2007. a total of 11,656 salmonella isolates covering all 6 years were included in the study. the top 10 salmonella serovars identified during the course of this study were enteritidis, stanley, weltevreden, rissen, i [1],4,[5],12:i:-, choleraesuis, anatum, typhimurium, corvallis, and panama, whi ... | 2009 | 19735204 |
| the sarcocystis-cyst containing beef and pork as the sources of natural intestinal sarcocystosis in thai people. | human intestinal sarcocystosis is a zoonotic disease caused by two coccidians, i.e. sarcocystis fusiformis (syn. s. bovihominis, s. hominis) due to consumption of raw infected beef and sarcocystis meischeriana (syn. s. suihominis) due to consumption of infected raw pork. in 1987, survey of the macroscopic s. fusiformis cysts in market beef mainly from old water buffalos aged more than 15 years were commonly observed in bangkok. in 2005, the macroscopic cyst was no longer seen in beef of cattle a ... | 2007 | 18041433 |
| prevalence of foodborne microorganisms in retail foods in thailand. | worldwide, foodborne illness is often associated with consumption of meats and poultry products sold at retail markets. a cross-sectional retail food study was conducted in bangkok, thailand to assess the prevalence of bacterial pathogens on retail food samples. raw chicken, beef, pork, and chicken eggs were purchased from fresh markets and supermarkets and tested for salmonella spp., campylobacter spp., arcobacter spp., and enterococcus spp. suspect bacterial pathogens were isolated by differen ... | 2007 | 17600488 |
