Multiplex PCR assay for identification of human diarrheagenic Escherichia coli.
Claudia Toma,Yan Lu,Naomi Higa,Noboru Nakasone,Isabel Chinen,Ariela Baschkier,Marta Rivas,Masaaki Iwanaga +7 more
TL;DR: This assay allowed the categorization of a diarrheagenic E. coli strain in a single reaction tube and selected targets selected for each category were eae for enteropathogenic E coli, stx for Shiga toxin-producing E. bacteria, and aggR for enteroaggregative E coli.

Culture conditions for stimulating cholera toxin production by Vibrio cholerae O1 El Tor.
Masaaki Iwanaga,Koichiro Yamamoto,Naomi Higa,Yoshio Ichinose,Noboru Nakasone,Masao J. Tanabe +5 more
TL;DR: A method that stimulates cholera toxin (CT) production by Vibrio cholerae O1 biotype El Tor (El Tor vibrios) to the level of several micrograms per ml in the culture fluid was established and a large amount of CT was obtained.

A Vibrio cholerae protease needed for killing of Caenorhabditis elegans has a role in protection from natural predator grazing.
Karolis Vaitkevicius,Barbro Lindmark,Gangwei Ou,Tianyan Song,Claudia Toma,Masaaki Iwanaga,Jun Zhu,Agneta Andersson,Marie-Louise Hammarström,Simon Tuck,Sun Nyunt Wai +10 more
TL;DR: A key role for PrtV is demonstrated in V. cholerae interaction with grazing predators, and Caenorhabditis elegans is established as a convenient organism for identification of V. Cholerae factors involved in host interactions and environmental persistence.

Efficacy of agar-plate culture in detection of Strongyloides stercoralis infection.
TL;DR: Agar-plate culture of feces using a modified petri dish proved to be highly efficient in the detection of Strongyloides stercoralis infection.

Antibiotic Resistance Conferred by a Class I Integron and SXT Constin in Vibrio cholerae O1 Strains Isolated in Laos
Masaaki Iwanaga,Claudia Toma,Tomoko Miyazato,Sithat Insisiengmay,Noboru Nakasone,Masahiko Ehara +5 more
TL;DR: Analysis of SXTLAOS showed that there is a continuous flux of genes among V. cholerae SXT constins which should be carefully monitored.
