Serological cross reaction between legionella and campylobacter in the rapid microagglutination test.
AIMS To investigate the serological cross reaction between legionella and campylobacter using the rapid microagglutination test (RMAT). METHODS Serum samples from 49 patients with campylobacter infection were tested for legionella antibodies using the indirect fluorescent antibody test (IFAT) and the RMAT. Serum samples that had positive RMAT titres were retested in the presence of a campylob...
متن کاملValidation of Legionella pneumophila indirect immunofluorescence assay with epidemic sera.
Sera from six outbreaks of legionellosis and four outbreaks of pneumonia of other etiologies were tested with the indirect immunofluorescence assay (IFA) as currently performed. The current IFA is at least as sensitive as the original test in detecting cases of Legionnaires disease (78 to 91%). By using Center for Disease Control criteria for a positive (fourfold increase in titer during conval...
متن کاملSerological differences in Legionella pneumophila infections.
Guinea pigs were infected with two subtypes of Legionella pneumophila serogroup 1 (UH1 and RH1). Seroconversion by indirect fluorescent-antibody assay was demonstrated in 94 to 97% of guinea pigs when the challenge strain was used as the antigen. The standard Philadelphia 1 antigen demonstrated seroconversion in 94% UH1-challenged animals, but in only 66% of RH1-challenged animals.
متن کاملA rapid microagglutination test for the diagnosis of Legionella pneumophila (serogroup 1) infection.
A rapid microagglutination test has been developed which can be performed in 30 minutes. Ninety-seven percent of 96 patients diagnosed as having Legionella pneumophila (serogroup 1) infection by indirect immunofluorescence were also detected by the rapid microagglutination test.
متن کاملIndirect immunofluorescence antibodies to Legionella pneumophila: frequency in a rural community.
The background prevalence of indirect immunofluorescence antibody to Legionella pneumophila in a rural community was determined by testing sera from 517 volunteers. The upper limit of normal antibody titer was found to be 1:64 with L. pneumophila serogroup 1 (Philadelphia 1) used as antigen. High titers (greater than or equal to 1:128) were found in 13.2% of the sera and occurred with similar f...
