Original Species

Using the complement fixation test, we found three different antigenic components in established cell strains originating from man and mouse:1. the antigenic property of the original species specifity. It resides in cell substances which, in a serological sense, are haptenes.2. an acquired antigenic property of species specifity of beef, which is a haptene too. The cells acquired this antigenic component from substances in the culture medium containing 20% of calf serum.3. an antigenic property characterized as a complete antigen which, probably, was acquired by the cells only during their in vitro-life. The nature of this third antigen is not yet entirely clear.

Abstract 1. A rabbit anti-DBA2-mouse-induced lymphogenous leukemia serum was prepared that contained antibodies to normal lymphocytic and to leukemic lymphocytic antigens, as determined by the complement fixation test of Thornton and his associates. 2. When this antiserum was incubated with normal lymphocytic antigen, all of its complement fixing activity was removed except that which reacted with the leukemic tissue. It appears that an antibody or group of antibodies was produced which was specific for this leukemia. 3. An antiserum to lymphogenous leukemia, induced in DBA2 mice, given prophylactically or therapeutically, did not significantly protect other DBA2 mice that had been inoculated with a transplantable leukemia of the same cell type. 4. The failure to induce leukemia in young, DBA2 female mice by painting them with 20-methylcholanthrene in benzene is reported.

Methodological Problems

ABSTRACT This report is a summary of 10 years of experience with the complement fixation test as adopted for the immunoassay of HCG in serum. It is based on published as well as unpublished material. The discussion centers mainly around methodological problems, criteria of reliability, and clinical observations. It is our impression that the complement fixation test is a reasonably rapid and simple technical procedure. It is standard practice in every bacteriological and virological laboratory. The precision of the HCG assay is high. Its accuracy is good. The complement fixation assay, as reported here, fulfils the criteria of specificity. It has been evaluated by means of serological techniques and through comparison between biopotency and immunopotency of HCG in serum with reference to a common standard. Its application for routine as well as research work is illustrated.

Abstract The study was carried out in seven reproductive herds of pigs. In three of them reproductive disorders were observed. Three herds consisted of 10-50 and four consisted of 120-500 adult sows and they were called small and medium, respectively. Fifty-seven adult sows were randomly selected from herds. Serum samples were tested using the complement fixation test and swabs from both eyes and from the vaginal vestibule were examined using real-time PCR. All serum samples were negative. Infected sows were present in each of the study herds. In total, there were 28 positive samples (53%, 28/48) in real-time PCR in sows with reproductive disorders and 35 (53%, 35/66) in sows selected from herds without problems in reproduction. One isolate proved to be Chlamydophila pecorum, whereas all the remaining were Chamydia suis

ABSTRACT The efficacy of Brucella abortus RB51 and hot saline extract (HSE) from Brucella ovis as antigens in complement fixation (CF) tests was comparatively evaluated in detecting immune responses of sheep vaccinated with B. abortus strain RB51. For this study, four 5-month-old sheep were vaccinated subcutaneously with 5 × 109 CFU of RB51, and two sheep received saline. Serum samples collected at different times after vaccination were tested for the presence of antibodies to RB51 by a CF test with RB51 as antigen, previously deprived of anticomplementary activity, and with HSE antigen, which already used as the official antigen to detectB. ovis-infected sheep. The results showed that vaccinated sheep developed antibodies which reacted weakly against HSE antigen and these antibodies were detectable for 30 days after vaccination. However, antibodies to RB51 could be detected for a longer period after vaccination by using homologous RB51 antigen in CF tests. In fact, high titers were still present at 110 days postvaccination with RB51 antigen. Sera from sheep naturally infected with B. ovisalso reacted to RB51 but gave lower titers than those detected by HSE antigen. As expected, all sera from RB51-vaccinated sheep remained negative when tested with standard S-type Brucella standard antigens.
