| a cross-sectional study of salmonella in pork products in chiang mai, thailand. | the occurrence of salmonella in food of animal origin in chiang mai province was investigated by using a cross-sectional study during several phases of the pork production chain (cutting, transport, and retail) and of the environment in the cutting unit of a slaughterhouse. in total, 173 pork samples were obtained during the cutting phase, 173 samples from transported pork, 200 samples from retail products, and 300 samples from the slaughterhouse environment. salmonella was detected in 55.5% of ... | 2010 | 20482229 |
| experimental infection of thailand taenia (chiengmai strain) in domestic animals. | twenty-five gravid proglottides of a thailand taenia were obtained from a patient in chiengmai, thailand, and brought to our laboratory. the tapeworm was determined to be t. saginata-like by counting uterine branches (mean number 16, range 12-19 on each side). the eggs from these proglottides remained infective under storage at room temperature for 14 days followed by refrigeration (4-8 degrees c) for 131 days. eight small-ear-miniature pigs and two holstein calves were each fed with 3000 eggs a ... | 1990 | 2312220 |

| novel porcine rotavirus of genotype p[27] shares new phylogenetic lineage with g2 porcine rotavirus strain. | a novel and unusual strain of porcine rotavirus (porv) cmp034 was isolated from a 7-week-old piglet during the epidemiological survey of porcine rotavirus infection in chiang mai province, thailand from june 2000 to july 2001. molecular characterization of gene vp4 by sequence analysis showed a low level of amino acid sequence identity, ranging from 56.7% to 76.6%, while comparison of vp8* portion showed 41.8% to 69.9% identity, with the 26 p genotypes recognized to date. phylogenetic analysis o ... | 2007 | 17215015 |
| streptococcus suis infection: a series of 41 cases from chiang mai university hospital. | the objectives of this study were (1) to assess the clinical manifestations, treatment, and outcome of streptococcus suis infection in adult patients in northern thailand, (2) to evaluate the anti-microbial sensitivity pattern and (3) to determine the predicting factors of high mortality rate. | 2006 | 16690131 |
| prevalence of salmonella and e. coli, and their resistance to antimicrobial agents, in farming communities in northern thailand. | a cross-sectional pilot study was conducted in chiang mai, thailand, to determine the prevalence of salmonella and escherichia coli in swine, broiler chickens and human workers from farms and abattoirs in northern thailand, and compare their antimicrobial resistance profiles. fecal samples and cloacal swabs were collected from 150 swine and 150 chickens at the farm. fecal samples from swine, cloacal swabs from chickens, and carcass swabs from both animals were collected from 100 swine and 100 ch ... | 2002 | 12971491 |
| identification of virulence-associated antigens and plasmids in rhodococcus equi from patients with acquired immune deficiency syndrome and prevalence of virulent r. equi in soil collected from domestic animal farms in chiang mai, thailand. | the prevalence of virulent rhodococcus equi in soil collected from 17 domestic animal farms (from 12 cattle, 1 pig, and 4 horse farms) and in 6 clinical specimens from patients with acquired immune deficiency syndrome (aids) in chiang mai, thailand, was investigated. the isolates were tested for the presence of 15-17-kda antigens (vapa) and a 20-kda antigen (vapb) by immunoblotting and for the presence of virulence plasmid dna. rhodococcus equi was isolated from most soil samples (68 of 80) obta ... | 2002 | 12135268 |
| heterogeneity in the host preference of japanese encephalitis vectors in chiang mai, northern thailand. | experiments, using the capture-mark-release-recapture technique inside large nets, were carried out in chiang mai, northern thailand, to examine heterogeneity in the host preference of japanese encephalitis (je) vectors. a significantly higher proportion of the vector species that were initially attracted to a cow fed when released into a net with a cow than when released into a net containing a pig. however, culex vishnui individuals that had been attracted to a pig had a higher feeding rate in ... | 2000 | 10974986 |
