High Burden of Extended-Spectrum β-Lactamase–Producing Escherichia coli and Klebsiella pneumoniae Bacteremia in Older Adults: A Seven-Year Study in Two Rural Thai Provinces
Pongpun Sawatwong,Pongpun Sawatwong,Patranuch Sapchookul,Toni Whistler,Christopher J. Gregory,Ornuma Sangwichian,Sirirat Makprasert,Possawat Jorakate,Prasong Srisaengchai,Somsak Thamthitiwat,Chidchanok Promkong,Pongnapat Nanvatthanachod,Muthita Vanaporn,Julia Rhodes +13 more
TL;DR: In this article, the authors aimed to expand their understanding of ESBL-producing pathogen disease burden by estimating trends in population-based E. coli and K. pneumoniae bacteremia incidence, changes over time in the proportion of these cases due to ESBL producing organisms, susceptibility profiles to other antibiotics, and the probability of recurrent infections.
Journal ArticleDOI

Watson,Maria Deloria Knoll,Wantana Paveenkittiporn,Chuwattana Chara,Cameron Hurst,Pasakorn Akarasewi,Julia Rhodes,Susan A. Maloney,Katherine L. O'Brien,Henry C. Baggett +16 more
TL;DR: Pneumococcal colonization is common among children aged <5 years in Thailand, however, colonization density was not higher among children with severe pneumonia compared to controls, which can inform discussions about PCV introduction and provide baseline data to monitor PCV impact after introduction in Thailand.
Short Report: Incidence of Bacteremic Melioidosis in Eastern and Northeastern Thailand
Saithip Bhengsri,Henry C. Baggett,Somsak Thamthitiwat,Somrak Chantra,Prasert Salika,Surang Dejsirilert,Leonard F. Peruski,Susan A. Maloney +7 more
TL;DR: In a recent study as discussed by the authors, the authors estimated the incidence of Melioidosis in Thailand as 4.4 cases per 100,000 and a population mortality rate (PMR) of 0.01 per 100 000 in 2008.
Journal ArticleDOI

TL;DR: Influenza-associated hospitalization rates in Thailand during 2009–10 were substantial and exceeded rates described in western countries, and expanded influenza vaccination coverage could have considerable public health impact, especially in young children.
Journal ArticleDOI
Population-based bloodstream infection surveillance in rural Thailand, 2007–2014

TL;DR: The most commonly observed pathogens including resistance profiles were similar to leading pathogens and resistance profiles worldwide, thus; prevention strategies with demonstrated success elsewhere may prove effective in Thailand.
