Serological Studies of Swine Erysipelas with Particular Reference to Agglutination
نویسندگان
چکیده
When the results of previous investigations ^ on the agglutination test for swine erysipelas were reported, information was not available as to the time of the appearance and stability of agglutinins in the blood stream of swine following infection. To obtain data on this point, a series of observations and agglutination tests on artificially infected swine was made. Information on the subject also has recently been received from the field. These data are reported in the present paper, together with other experimental data obtained from the agglutination tests of blood serum from swine and from persons who were suspected of being infected with Erysipelothrix rhusiopathiae. A rapid serological method of identifying cultures of E. rhusiopathiae is also reported.

Potency Testing of Swine Erysipelas Vaccines by Serology Results of a Pre-validation Study.
The European Pharmacopoeia (Ph. Eur.) monograph on Swine Erysipelas Vaccine (inactivated) (Ph. Eur., 1997) requires the potency of each batch to be demonstrated in a mouse protection test. In this parallel-line bioassay, mice are challenged with a virulent strain of Erysipelothrix (E.) rhusiopathiae after immunisation with different doses of either the standard preparation or of the test vaccin...

The conclusions to be drawn from this study are that while there appears to be evidence of serological distinctions between B. abortus and B. melitensis cultures as studied by earlier workers, the experiments reported in this paper show no serological distinctions among the six strains used in the study. B. melitensis II and B. melitensis III were found to be identical with the bovine and swine...
متن کاملOccurrence of leptospiral infections in swine population in Poland evaluated by ELISA and microscopic agglutination test.
Swine are one of significant reservoirs and sources of Leptospira infections for man. Serological screenings help to effectively control the epidemiological situation in swine herds and to prevent transmission of Leptospira from animals to man. The purpose of this study was to investigate, by the use of serological methods, the prevalence of infections caused by selected Leptospira serogroups i...

1. Strains of hemolytic streptococci isolated from cases of erysipelas agglutinate in a high percentage of instances with erysipelas immune sera. When agglutination occurs with one serum, the strain usually agglutinates with all other erysipelas sera. 2. Erysipelas immune sera agglutinate strains from erysipelas in a higher percentage of instances than they agglutinate scarlatinal strains. 3. S...
متن کاملOccurrence of Leptospira Sp. Antibodies in Swine in Poland
The aim of the study was to evaluate the prevalence of antibodies specific to different serogroups of Leptospira sp. in swine populations in Poland. The serological survey was conducted in 2006. A total of 7 252 swine serum samples coming from all provinces of the country were investigated. The samples were examined by the use of a microscopic agglutination test. As antigens, six Leptospira ser...
