Abstract We experienced two cases of salmonellosis (bacteremia and urinary tract infection) caused by rare Salmonella spp. during early infancy. In the bacteremia case, serotype could not be determined using commercially available O antigens. Multi-locus sequence typing analysis, and O antigen and H antigen based on PCR and nucleotide sequence analysis were useful for determining specific serotype. The final diagnosis of these salmonellosis was bacteremia caused by Salmonella enterica subsp. enterica serovar Pomona and upper urinary tract infection caused by Salmonella Fluntern, respectively. Identification of Salmonella serotypes was clinically useful. Molecular biological techniques are useful for estimating the serotype of Salmonella spp. when matching antisera are not available.
