Pulmonary Aspergillosis in Ostrich

Serological tests for syphilis.

Many of the nontreponemal or serological tests for syphilis involve the detection of serum antibodies (reagin) which are not directed against a component of the causative organism itself but may arise as a result of pathological changes brought about by proliferation of Treponema pallidum in host tissue. Test antigens for the detection of reagin are lipoidal, the main active component being the...

Serological Tests for Syphilis.

In a pilot study by field-screening in two different sauna baths, a day-sauna and a night-sauna, 318 homosexual men were investigated for syphilis and hepatitis B surface antigen (HBsAg) and its antibody (anti-HBs). Of the 134 visitors to the day-sauna 35 1-o were seroreactive for syphilis, four (3%) carried HBsAg, and 95 (70' 9%) anti-HBs. Of the 184 visitors to the night-sauna 33' 2% were ser...

Serological Tests

Serological diagnosis of an acute infection can be done by the demonstration of seroconversion and/or agent-specific IgM antibodies in the serum samples. Seroconversion describes 4 fold or more increase in antibody levels of the serum samples which is collected at the acute and convelescent phase (10-15 days intervals) of an infection. As the detection of seroconversion is time-consuming, the a...

Evaluation of a Quantitative Serological Assay for Diagnosing Chronic Pulmonary Aspergillosis

The purpose of this study was to evaluate the clinical utility of a quantitative Aspergillus IgG assay for diagnosing chronic pulmonary aspergillosis. We examined Aspergillus-specific IgG levels in patients who met the following criteria: (i) chronic (duration of >3 months) pulmonary or systemic symptoms, (ii) radiological evidence of a progressive (over months or years) pulmonary lesion with s...
