Sexual transmitted Infection - Essay Example Chlamydia trachomatis is one of the most commonly diagnosed bacterial sexually transmitted infection. In women, it causes endometritis, mucopurulent cervicitis and urethritis. Mucopurulent cervicitis can cause of pelvic inflammatory disease, salpingitis, ectopic pregnancy, tubal factor infertility, chorioamnionitis, puerperal and neonatal infections and epididymitis. In men, untreated chlamydial infections can cause epididymitis and proctitis. Chlamydia is associated with an elevated risk of transmission of HIV and for the development of cervical carcinoma. Women are the potential source of infection to their partners since they carry the major burden of the disease (Malhotra, et al., 2013). In men, C. trachomatis can cause acute epididymis, nongonococcal urethritis and urethral strictures (Shaw, et al., 2011). Chlamydia is often asymptomatic but patients may experience pain during urination, unusual discharge from the vagina, penis and rectum. Women may experience abdominal pain, bl eeding during or after sex and bleeding in between periods while men have swelling in the testicles. Chlamydia trachomatis diagnosis is done through nucleic acid amplification tests such as polymerase chain reaction, ligase chain reaction, and transcription mediated amplification assays since they are non-invasive and perform well. The tests are highly specific and are more sensitive compared to the traditional method of tissue culture. Enzyme immune assays and direct nucleic acid probe assays can also be used in detecting chlamydial.

Can other parts of a crime lab be as scientific as the DNA lab Essay

Can other parts of a crime lab be as scientific as the DNA lab - Essay Example Many police and anti-crime organizations the world over still rely on fingerprint evidence to track down a criminal but this technique has recently been put into doubt. Part of the reason is that new DNA technique is more accurate and reliable but most organizations lack the expensive equipment and expertise to do DNA testing. However, experts claim fingerprinting is not 100% fool-proof or reliable. Overview of fingerprinting – the first-ever precedent-setting criminal case in which the only evidence of fingerprints left at the crime scene was used to convict a suspect was the Rojas murders; this was a case in Necochea, Argentina back in 1892 in which the mother killed her two young children but originally accused her neighbor of the twin murders. However, when she was confronted with the incriminating evidence of bloody fingerprints on her door post, she admitted to the crime. Prior to fingerprinting, there was also the Bertillion system that had utilized a set of body measurements to identify and classify people; it was named after Alphonse Bertillion who was a French anthropologist. However, the famous case of Will West – William West in which two people had the same measurements, had almost the same names also and almost identical facial features (based from their photographs) called his systems reliability into question and caused doubts among criminologists. Fingerprinting was found to be reliable than the Bertillion system, in the same way that DNA testing is today more reliable than fingerprinting. Basic scientific principles – the method of fingerprinting was first developed by a great British anthropologist named Sir Francis Galton who first suggested the use of fingerprints based on the uniqueness of very minute details. It was another Englishman named Sir Edward Henry, assigned to Bengal, India as inspector general of the police during the
