conclusions findings of this study demonstrate no significant difference between levels of h. pylori specific antibodies of iga, igg, anti-caga and the presence of pcos disorders, and also indicate that serologic testing is a sensitive method for the detection of h. pylori antibodies. the high prevalence of h. pylori positive antibody levels in both pcos and non-pcos patients can be probably as...

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...

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...

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...
