Human cases caused by <jats:italic>Trichuris suis<\/jats:italic> and <jats:italic>Trichuris vulpis<\/jats:italic> have also been reported. Molecular identifications of <jats:italic>Trichuris<\/jats:italic> species infecting human populations in Lao PDR and Myanmar are lacking. Here, we explored molecular data obtained from <jats:italic>Trichuris<\/jats:italic> eggs recovered from human fecal samples from these countries and compared these with new and existing data from Thailand. Nuclear ribosomal DNA (18S and ITS2) sequences were amplified from <jats:italic>Trichuris<\/jats:italic> eggs and sequenced. Forty-one samples showed 99\u2013100% similarity in their 18S sequences to published sequences of <jats:italic>T. trichiura<\/jats:italic> and one sample showed 99% similarity to a sequence of <jats:italic>T. suis<\/jats:italic>. Similarly, 41 samples showed 92\u2013100% similarity in their ITS2 sequences to published sequences of <jats:italic>T. trichiura<\/jats:italic> and one sample showed 94\u201397% similarity to sequences of <jats:italic>T. suis<\/jats:italic>. This study is the first molecular confirmation of human infection with <jats:italic>T. suis<\/jats:italic> in northeast Thailand and the first molecular confirmation of the species of
