To determine the prevalence of CTX-M β-lactamase-producing Enterobacteriaceae and to study risk factors associated with faecal carriage in asymptomatic rural Thai people. In all, 417 stool samples were obtained from people screened for extended-spectrum β-lactamases (ESBLs) using MacConkey agar supplemented 2 mg/L cefotaxime. Results confirmed cefotaxime ceftazidime without clavulanic acid. The blaCTX-M genes identified genotyped PCR bacterial DNA samples. Multivariate analysis was performed...
ObjectivesTo determine the prevalence of CTX-M β-lactamase-producing Enterobacteriaceae in stool specimens obtained from healthy individuals a rural area Thailand.
Abstract: Recent studies have reported a widespread distribution of extended-spectrum β-lactamase (ESBL)-producing bacteria, not only in the nosocomial setting, but also community; some local communities Southeast Asia been to show high prevalence ESBL-producing bacteria. However, details regarding quantitative/qualitative state bacterial spread are currently unclear. Thus, aim this study was assess community residents from Indochinese peninsula, as representative region Asia. In order...
The prevalence of and risk factors associated with extended-spectrum β-lactamase (ESBL)-producing micro-organisms have not been well studied in healthy individuals. aim this study was to determine individuals Thailand. Stool samples questionnaires obtained from 445 participants three provinces Thailand were analysed. antimicrobial susceptibility the isolates assessed using phenotypic genotypic methods. PCR analysis performed detect group bla CTX-M genes. CTX-M-type ESBL-producing...
Blastocystis sp. is a common zoonotic intestinal protozoa which has been classified into 17 subtypes (STs). A cross-sectional study was conducted to determine the prevalence and subtype distribution of in villagers living on Thai-Myanmar border, where risk parasitic infection high. total 207 stool samples were collected DNA extracted. PCR sequencing using primers targeting small-subunit ribosomal RNA (SSU rRNA) gene performed. The 37.2% (77/207). ST3 (19.8%; 41/207) predominant subtype,...
In 2006, the Thailand Ministry of Public Health studied 28 patients from a village in northern Thailand. All had myalgia, edema, fever, and gastrointestinal symptoms; most eaten wild boar. A muscle biopsy specimen patient showed nonencapsulated larvae with cytochrome oxidase I gene sequence Trichinella papuae.
A human trichinellosis outbreak caused by Trichinella papuae occurred in the Uthai Thani Province of Thailand September 2007. total 34 villagers suffering at least one symptoms suggestive trichinellosis, or those who were asymptomatic but had a history ingesting raw wild pig meat, enrolled study. Twenty-two ingested undercooked pork from hunted (Sus scrofa). One patient with severe clinical picture was hospitalised and more than 80 non-encapsulated larvae detected muscle biopsy. The...
Travelers' diarrhea is the most common disease reported among travelers visiting developing countries, including Southeast Asia, a region visited by large numbers of backpackers each year. Currently, knowledge travelers' this group limited. This study aimed to determine incidence and impact in group.Foreign Khao San road, Bangkok, Thailand, were invited fill out questionnaire, which they queried about their demographic background, travel characteristics, pretravel preparations actual...
The effect of origin and destination country on traveler's diarrhea incidence rates in Southeast Asia is poorly understood, research generally only addresses travelers from the developed world. This study evaluated attack rate effects by analyzed key risk factors. A self-administered questionnaire was provided to foreign departing Suvarnabhumi Airport, Bangkok, Thailand. It traveler demographics, relevant knowledge practices, experiences diarrhea, details consequences each diarrheal episode....
Abstract Gastrointestinal helminth infection likely affects the gut microbiome, in turn affecting host health. To investigate effect of intestinal parasite status on parasitic surveys were conducted communities Nan Province, Thailand. In total, 1047 participants submitted stool samples for examination, and 391 parasite-positive cases identified, equating to an prevalence 37.3%. Intestinal protozoan species less prevalent (4.6%) than species. The most was minute fluke Haplorchis taichui...
Quantitative fecal egg counts represented as the number of eggs per gram feces (EPG) are generally a reliable parameter to estimate worm burden intestinal and hepatic parasitoses. Although Haplorchis taichui (Digenea: Heterophyidae) is one most common minute human flukes, little known about relationship between EPG actual in patients or severity disease. In present study, samples were collected from 25 villagers northern Thailand before after praziquantel treatment. The values each...
The first workshop towards the control of cestode zoonoses in Asia and Africa was held Asahikawa Medical University, Japan on 15 16 Feb 2011. This meeting fully supported by Asian Science Technology Strategic Cooperation Promotion Programs sponsored Special Coordination Funds for Promoting Technology, Ministry Education (MEXT) 3 years from 2010 to Akira Ito. A total 24 researchers 9 countries joined together discussed present situation problems zoonoses. As simultaneously establishment joint...
Enterocytozoon bieneusi and Cryptosporidium spp. are prevalent zoonotic parasites associated with a high burden among children. To date only limited molecular epidemiological data on E. in humans living Thailand has been published.PCR-based tools were used to detect characterize The internal transcribed spacer (ITS) region of the rRNA gene was investigate bieneusi, small subunit (SSU) spp., 697 fecal samples from villagers school children rural areas analyzed.The infection rates 2.15%...
AbstractAbstractSoil-transmitted helminthiases are major parasitic diseases that cause health problems world-wide. School-based education is one of several basic interventions currently recommended by the World Health Organization for control these infections. A 3-year programme soil-transmitted helminths (STH) has recently been completed in four primary schools Hauykayeng subdistrict Thong Pha Phum district, Kanchanaburi province Thailand. Overall, percentage schoolchildren found infected...
Taenia saginata is the most common human in Thailand. By cox1 sequences, 73 isolates from four localities north and northeast were differentiated into 14 haplotypes, 11 variation sites haplotype diversity of 0.683. Among A was major (52.1%), followed by B (21.9%). Clustering diagram Thai GenBank sequences indicated mixed phylogeny among localities. MJ analysis, clustering relationships showed paired-stars-like network, having two main cores surrounded minor haplotypes. Tajima's D values...
Taeniasis remains a prevalent public health problem in Thailand. National helminthiasis surveys report only the incidence of Taenia spp. eggs. The ability to differentiate species using morphological and molecular techniques is vital for epidemiological surveys. This study detected taeniasis carriers other helminthic infections by Kato's thick smear technique identified multiplex PCR. subjects were ethnic Karen people Tha Song Yang District, Tak Province, Thailand, bordering Myanmar. In...
Abstract As part of the international joint projects working towards control taeniosis/cysticercosis in Asia Pacific, epidemiological studies on Taenia solium cysticercosis have been carried out high-incidence populations, such as minority groups Thailand. To assess epidemiology cysticercotic infections pigs hill-tribe villages (Karen) Tak province, Thailand, we conducted serological screening and necropsies. The patterns antibody response to T. antigens were then investigated using...
