Formalin-killed versus heat-killed Legionella pneumophila serogroup 1 antigen in the indirect immunofluorescence assay for legionellosis.

Indirect immunofluorescence assay titers of human sera obtained against the Legionella pneumophila serogroup 1 antigen (Philadelphia 1 strain) killed with 10% Formalin showed a tendency to be lower than those obtained against the reference heat-killed antigen (geometric mean titer of 194 and 370, respectively) when all other variables in the test were held constant. Test results were interprete...

Comparison of phenol- and heat-killed antigens in the indirect immunofluorescence test for serodiagnosis of Legionella pneumophila group 1 infections.

An antigen prepared with agar-grown Legionella pneumophila group 1 killed by 0.5% phenol and suspended in 0.5% yolk sac was examined for use in the indirect immunofluorescence test for legionellosis and compared with a heat-killed antigen. The serological results of the two antigens for single and paired sera agreed well. Morphological and staining characteristics were better for phenol-treated...

Polyvalent heat-killed antigen for the diagnosis of infection with Legionella pneumophila.

A polyvalent antigen composed of heat-killed agar-grown Legionella pneumophila serogroups 1-4 suspended in a suspension of yolk-sac from embryonated hens' eggs has been examined for use in the indirect fluorescent antibody test for Legionella infection. The serological response detected by monovalent antigen correlated well with that detected by polyvalent antigen. The use of polyvalent antigen...

Legionellosis from Legionella pneumophila Serogroup 13

We describe 4 cases of Legionella pneumophila serogroup 13-associated pneumonia. These cases originate from a broad geographic range that includes Scotland, Australia, and New Zealand. L. pneumophila serogroup 13 pneumonia has a clinically diverse spectrum that ranges from relatively mild, community-acquired pneumonia to potentially fatal severe pneumonia with multisystem organ failure. All cas...

Validation 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...
