During the last two or three years, the three largest hospitals in Stockton (St. Joseph’s, Dameron and San Joaquin General Hospitals) have modified their procedures to include the search for Campylobacter. On the other hand, the incidence of Yersinia in California is unknown, as most clinical laboratories do not specifically culture for it. There have been only a few reports of Yersinia in this state (personal communication of Dennis Ferrero, Director of the San Joaquin County Public Health Laboratory). This study has a threefold purpose: to investigate the incidences of Campylobacter and Yersinia, especially in relation to the incidence of Salmonella and Shigella, to study the biochemical and antibiogram characteristics of enteric isolates, particularly the “newer” pathogens, and to review the state of routine culture methods and assess their adequacy.
