A series of episodes of acute otitis media were studied with reference to the bacterial findings in the nasopharynx and the specific antibody response in a group of children nine months to ten years of age, with previous frequent episodes of acute otitis media, Serum IgG, IgM and IgA antibody levels against five polysaccharide antigens, namely Haemophilus influenzae type b and Streptococcus pneumoniae types 3, 6, 19 and 23, were studied by means of an enzyme-linked immunosorbent assay. The selection of polysaccharide antigens was based on isolation frequency. The sera to be tested were tenfold serially diluted. An extinction of 0.2 over the base was taken as the end-point titer and expressed as in-log10. The results showed that most children including those under three years of age showed increasing homologous antibody titers at an infection, or had already initially very high antibody titers, especially of the IgG class. The titers reached levels of 104 to 105. In some cases, however, it could be shown that high serum antibody titers did not give protection against a new infection with the same serological type of bacteria. It was also demonstrated that most children, regardless of age, had IgG and IgM titers against the heterologous antigens. In some cases the levels were quite high (103 to 104). However, the IgA antibody levels were lower and in a considerable number of samples antibodies were not even detectable.

Aims: The aim of this study was to evaluate the presence of Porphyromonas gingivalis (Pg) the in subgingival biofilm, as well as to compare the immune responses of postpartum women and their newborns to Porphyromonas gingivalis using antibody serum levels.Methods: A total of 43 postpartum women and 24 newborns were selected in the municipal maternity hospital of Alagoinhas, Bahia, Brazil between February and December 2003, for this cross-sectional study. The presence of Pg was verified using polymerase chain reaction. The immunoglobulin serum levels: IgG1, IgG2, IgG3, IgG4 and IgA, reactive to Pg ATCC33277, were tested using ELISA. Results: 39,3% of the postpartum women biofilm samples were positive for Pg. The incidence of the pathogen in the women with periodontitis (70%) was higher than in the group of women without periodontitis (30,30%). Among the newborns, high serum levels of IgG4 anti-Pg were observed (p<0.001).Conclusion: Our findings confirm that postpartum women with periodontitis present remarkable incidence of Porphyromonas gingivalis which may influence systemic response, as represented by high levels of serum antibody levels against this pathogen in women and newborns. Furthermore, evidence suggests that some antibodies crossed the placental barrier in newborns.

SUMMARYThe serum antibody responses and 50% protective levels (PL50) of antibody were determined, using the SRH test, at one and twelve months post-vaccination in a group of student volunteers immunized with one of three dosages of a trivalent surface-antigen influenza virus vaccine, or with placebo.It was found that, for the H3, H1 and B haemagglutinin components present in the vaccine, a dose of 6 μg HA elicited high serum antibody responses at one month post-immunization. High mean antibody levels and a high incidence of volunteers with PL50 values of antibody against each of the HA components of the vaccine remained in the volunteer group twelve months later. The results are discussed in relation to the vaccine dosage used and the nature of the population immunized.

The humoral antibody response and the number of pronephric antibody-secreting cells were examined in naturally Bothriocephalus acheilognathi-infected carp. Cyprinus carpio, and in those injected intraperitoneally with an extract of the cestode. In the extract-injected fish, specific antibody was detected 3 weeks after a second injection given 2 weeks after the primary injection, and antibody levels persisted for more than 200 days. A third injection also enhanced the antibody level in the extract-injected carp. The numbers of antibody-secreting cells were significantly higher in carp injected 3 times with the extract than in the control. In naturally-infected fish, the serum antibody levels and the number of pronephric antibody-secreting cells were higher in infected fish than in uninfected individuals although this difference was not statistically significant. The relevance of these results to immune protection against infection is discussed.

Patients with chronic urinary and urogenital multidrug resistant bacterial infections received phage therapy (PT) using intravesical or intravesical and intravaginal phage administration. A single course of PT did not induce significant serum antibody responses against administered phage. Whilst the second cycle of PT caused a significant increase in antibody levels, they nevertheless remained quite low. These data combined with good therapy results achieved in some patients suggest that this mode of PT may be an efficient means of therapy for urogenital infections and a reliable model for a clinical trial of PT.
