BACKGROUND The hepatitis B, hepatitis C, human immunodeficiency viruses and Treponema pallidum are important causes of infectious diseases concern to public health. METHODS Between 2010 and 2014, we used an automated chemiluminescence microparticle immunoassay to detect the hepatitis B, hepatitis C, and human immunodeficiency viruses as well as Treponema pallidum (the rapid plasma regain test...

Syphilis is considered one of the greatest imitators which can mimic any skin disease. Keen examination together with a sound brain and high degree suspicion required for its diagnosis. Syphilis, sexually transmitted disease caused by spirochete Treponema pallidum pallidum, was more common during Second World War. Later, as human immunodeficiency virus cases increased, there increased,incidence...

We have recently shown that syphilitic rabbits are resistant to challenge with Listeria monocytogenes. This resistance was thought to reflect stimulation of cell-mediated immunity by active infection with Treponema pallidum. We now report data which show that the growth of Listeria was not suppressed in mice inoculated with T. pallidum. Re-inoculation with T, pallidum or with a large dose of an...
