Syphilis is primarily a venereal disease, but it can also be obtained from direct exposure to infected blood. The pathogen is capable of crossing the placenta and infecting an unborn child. Untreated, the disease typically goes through four stages of development: the primary stage, the secondary stage, the latent stage, and the tertiary stage (Wikipedia)…

Introduction

T pallidum is a labile organism that will not endure drying or exposure to disinfectants (CDC). It is primarily a human pathogen, and does not seem to occur naturally in other species. Soon after the early infection sets in, the pathogen enters the lymphatic system and the blood stream. It then spreads throughout the entire body. Nearly all of the organs can be invaded by the pathogen, including the central nervous system.
The primary symptoms associated with Syphilis are characterized by a painless chancre sore at the area of entry near the genital region (Wikipedia). This lesion does not always develop, and sometimes multiple sores appear. Lymphadenopathy often accompanies the chancre sores (Department of Health). Most of these initial sores heal within 3-6 weeks of the original infection. The emergence of secondary Syphilis, which usually begins as the first outbreak is healing, is associated with a scattered rash, condyloma lata, lymphadenopathy, and several other symptoms such as high fever (CDC). Because the active bacteria is present in the lesions any physical contact-sexual or otherwise-may spread the infection to another person during this stage. ...

Tuskegee Syphillis study and Johns Hopkins lead paint research are some of the controversial medical researches conducted in the past without taking permission from the subjects. This paper critically analyses these two studies. Tuskegee Syphillis study was arguably the most infamous medical study conducted in the history of American medical science. This controversial clinical study was conducted…

Neurosyphilis, ocular syphilis and other visceral syphilis are mentioned. Co-infection with HIV is a significant feature in United States and it has been discussed in relation to the syphilitic infection. The treponemal and nontreponemal tests are two diagnostic tests used for the detection of syphilis in individuals. The antibiotic treatment, penicillin benzathione G, is an established treatment…

The Tuskegee experiment is the most prominent example of the conflicts between medical research and ethics. Instead of treating the participants with penicillin during the experiment, medical researchers withheld it. They ignored the ethical rules recommended for an effective research. The negative impact of the experiment affected future medical research related to venereal diseases such as…
Ethics
While the initial study was designed to last for a year and where participants with syphilis were given minimal treatment which would have definitely not cured them, the extended study examined men with untreated syphilis over the 40 year period and in case they died during that period their bodies autopsied to study the exact course of the infection (Angell, 1997; Sugarman, 2002). The PHS took…
Disease report
Healthcare providers will usually suspect the presence of Q fever in people who are suspected to have been exposed to the pathogen and who develop pneumonia, hepatitis, flu-like symptoms, and endocarditis (Mandell et al 51). Symptoms usually occur after approximately 20 days of exposure with most cases presenting mildly, although some severe cases do occur. Common initial symptoms of the disease…

The first report of a syphilis epidemic was in the mid 1490s when it occurred among French soldiers laying siege to Naples.

Yet, syphilis still represents a sizeable morbidity. Some factors are specifically blamed for the last 20 years…
