A monoclonal antibody, SBY1 (IgM, kappa), against the Salmonella O-antigen was generated by using the myeloma cell line Sp2/O-Ag14 as a fusion partner with spleen cells from BALB/c mice immunized with S. senftenberg 963 K. SBY1 was characterized by the slide agglutination and absorption test. SBY1 was believed to show the specificity to O1-, O3- or O19-antigens of Salmonella because S. Senftenberg 963 K (O1, 3, 19) was used as the antigen for immunization. The slide agglutination test with the Salmonella serovars indicated the responsiveness of SBY1. SBY1 was reactive only with strains that possessed O19-antigen. The agglutinating ability of SBY1 was absorbed completely with bacilli possessing O19-antigen. These finding indicates that SBY1 is specific for O19-antigen. Polyclonal factor sera for he serotyping of the O3, 10 group of Salmonella cross-reacted with Salmonella group O1, 3, 19 in the slide agglutination test. In contrast, SBY1 did not cross-react with serovars from several other Salmonella groups. These data suggest the usefulness of SBY1 as a serodiagnostic tool for serotyping of Salmonella.

Positive blood cultures reported between 1986 and 1993 at the Tokyo Metropolitan Komagome Hospital were evaluated and all patients with an intravenous hyperalimentation catheter who developed candidemia, a total of 94 patients, were analyzed further, while patients with neutropenia were excluded. The primary diagnosis was malignancy in 87.2% of the cases, and Candida albicans and C. parapsilosis were the main organisms detected. A total of 17 patients died from candidemia. The patients who were positive for C. parapsilosis, however, all survived in spite of the fact that their main treatment was only removal of the catheter (20/32 cases), while eight of 25 patients who developed fungemia due to C. albicans died from the fungemia (p = 0.001). There were no significant differences in their risk factors. Because of the better outcome for the patients who developed candidemia due to C. parapsilosis, we might be able to consider less aggressive treatment for such patients.

Campylobacter jejuni strains isolated from gastroenteritis at 4 general hospitals of Tokyo Metropolitan during the period from 1981 to 1987 were serotype according to the slide agglutination test (TCK system) developed by the Tokyo Metropolitan Research Laboratory of Public Health. Two thousand four hundred seventy-nine strains isolated from sporadic cases among infants and children, 1,962 (78.5%) were typed by 33 typing sera numbered TCK 1 through TCK 33 and leaving 537 strains (21.5%) untypable. Out of the typable strains, 1,643 strains reacted with only single serum, while 319 strains reacted with 2 or more antisera. The most common serogroups included TCK 21, 20, 7, 1, 4, 23, 24, 10, 30 and 12. Out of the 1,250 strains isolated from sporadic cases among adults, 974 strains (77.9%) were typed and 276 strains were untypable. The most common serogroups were similar to those of infants and children. Serogroups TCK 1, 7, 4 and 21 were consistently the common serogroups every year during the 7 year study. Isolation frequency of serogroup TCK 30 have increased remarkably since 1986, while TCK 23, 14 and 9 have decreased.
