Mahidol University Library and Knowledge Center, 2005) Peerasak Nichayapun; Sumalee TungpradabkulPublication Metadata only Identification of uncommon pathogenic bacteria by MALDI-TOF mass spectrometry using a custom library of siriraj hospital(2018-03-01) Kanda Ekcharoenkul; Popchai Ngamskulrungroj; Keerati Joyjamras; Amornrut Leelaporn; Azian Harun; Pattarachai Kiratisin; Faculty of Medicine, Siriraj Hospital, Mahidol University; School of Medical Sciences - Universiti Sains Malaysiafor bacterial identification in microbiology laboratories. This study aimed to determine the performance of MALDI-TOF MS for identifying uncommon and/ or fastidious bacteria comparing with automated identification method. Methods: We observed the performances... of original and extended databases after adding of in-house MALDI-TOF MS database for a total of 54 isolates belonging to 16 genera of uncommon and/or fastidious bacteria. Results: The extended database improved identification of these bacteria significantlyItem Metadata only Identification and purification of a bacteriocin secreted by lactic acid bacteria isolated from traditional thai fermented food(Mahidol University. Mahidol University Library and Knowledge Center, 2007) Kanjana Wittayacom; Wilai NoonpakdeeItem Metadata only FTIR as possible tool for bacterial identification and bound carbonyl in poly (methl methacrylate) adsorbed on silica(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Suntree Kulkeratiyut; Byaporn na NagaraPublication Metadata only Rapid identification and enumeration of antibiotic resistant bacteria in urban canals by microcolony-fluorescence in situ hybridization(2006-12-18) Takehiko Kenzaka; Nobuyasu Yamaguchi; Fuangfa Utrarachkij; Orasa Suthienkul; Masao Nasu; Faculty of Environment and Resource Studies, Mahidol University; Osaka University; Mahidol UniversityThe abundance and phylogenetic composition of antibiotic resistant bacteria in canals of metropolitan Bangkok, Thailand, were investigated using a microcolony method and fluorescence in situ hybridization (FISH). Cells were directly trapped from... of Escherichia coli (E. coli) determined by FISH with rRNA-targeted probe accounted for approximately 1% of bacteria detectable by probe EUB338 among microcolony-forming bacteria on nonselective medium. However, they accounted for approximately 10% of bacteriaItem Metadata only An investigation of concentration and identification of bacterial and fungal aerosols in indoor air environments in Siriraj Hospital(Mahidol University. Mahidol University Library and Knowledge Center, 2009) Suwat Damnin; Suttinun ChantanakulPublication Metadata only Identification and antimicrobial susceptibility of microorganisms isolated from severe corneal ulcers of dogs in Thailand(2018-08-01) Daneeya Ekapopphan; Athicha Srisutthakarn; Walasinee Moonarmart; Ruangrat Buddhirongawatr; Norasuthi Bangphoomi; Mahidol University.02) and the depth (P=0.04) of ulcers predicted greater risk of yielding resistant bacteria. The identification of antimicrobial-resistant bacteria prompts practitioners to be prudent when choosing ophthalmic antibiotics for severe corneal ulcers....©2018 The Japanese Society of Veterinary Science. This study aims to determine the microbiological profile and risk factors associated with antimicrobial-resistant bacteria in canine severe corneal ulcers. Thirty-two corneal and conjunctival swabsPublication Metadata only Identification of entomopathogenic nematodes and symbiotic bacteria from Nam Nao National Park in Thailand and larvicidal activity of symbiotic bacteria against Aedes aegypti and Aedes albopictus(2018-04-01) Temsiri Yooyangket; Paramaporn Muangpat; Raxsina Polseela; Sarunporn Tandhavanant; Aunchalee Thanwisai; Apichat Vitta; Naresuan University; Mahidol Universityare credited. Entomopathogenic nematodes (EPNs) that are symbiotically associated with Xenorhabdus and Photorhabdus bacteria can kill target insects via direct infection and toxin action. There are limited reports identifying such organisms in the National Park... of Thailand. Therefore, the objectives of this study were to identify EPNs and symbiotic bacteria from Nam Nao National Park, Phetchabun Province, Thailand and to evaluate the larvicidal activity of bacteria against Aedes aegypti and Ae. albopictus. A totalPublication Metadata only Identification and characterization of soil-isolated Streptomyces SJE177 producing actinomycin(2010-09-01) Jirayut Euanorasetr; Arjaree Nilvongse; Srisurang Tantimavanich; Takuya Nihira; Yusuhiro Igarashi; Watanalai Panbangred; Mahidol University; Osaka University; Toyama Prefectural UniversityOne hundred seventy-seven actinomycetes strains were isolated from soils collected from fruit orchards in Thailand. All were tested for antibacterial activity against seven pathogenic bacteria using co-cultivation methods. Forty strains (22.6%) were... active against at least one indicator bacteria. Twenty-seven strains (15.3%) inhibited only gram-positive bacteria, four strains (2.3%) inhibited only gram-negative bacteria, and nine strains (5.1%) showed activity against both. Strain SJE177 had potentItem Metadata only Identification and functional validation of kynureninases from oral bacteria(2025-01-01) Charoenwongwatthana P.; Ahmed H.; Charlton A.; Gidley M.D.; Telezhkin V.; Coulter J.; Chang C.Y.; Charoenwongwatthana P.; Mahidol University(KynU), which catalyses kynurenine to anthranilic acid (AA), in oral bacteria. Methods: Bioinformatic analysis identified putative kynU genes in oral bacterial genomes, and structural similarity of the predicted proteins was evaluated using Template...-MS). Results: Among 71 species, seven oral bacteria were identified to possess the kynU. Structural analyses indicated KynU from four species may fold into functional enzymes. Three recombinant KynU from Burkholderiacepacia, Ralstoniapickettii
