...Danielle Sauter-Henson Professor Davis BIOL 215-01 14 March 2017 Chlamydia Etiology Chlamydia trachomatis is among the most common bacteria transmitted within the united states. This specific type of chlamydia can cause several sexually transmitted and congenital diseases such as lymphogranuloma venereum and trachoma. They are nonmotile and their replication can only occur within vesicles of host cells. Originally, scientists believed that chlamydia was a virus because the size of it was small, and also because of its intracellular lifestyle. They later found this to be false because Chlamydia has functional 70s ribosomes, RNA and DNA, (Insert book citation). Two membranes surround chlamydia similar to that of a Gram-negative bacterium, however, they do not possess peptidoglycan and therefore also lack cell wall. The pathogenic structure of Chlamydia trachomatis is the elementary bodies. These elementary bodies start by attaching to the host receptor. They continue, initiating endocytosis within the host cell, causing them to be brought into the vesicle of the host cell. It is at this point that they transform into and initial body while within the vesicle. This initial body is the key to reproduction. These initial bodies multiply very quickly, and the vesicle...

...Journal Article November 22, 2011 “Chlamydia trachomatis Infection Among Women Reporting Sexual Activity With Women Screened in Family Planning Clinics in the Pacific Northwest ,1997 to 2005” Devika Singh ,David Fine, and Jeanne Marrazzo Introduction In 1907 Chlamydia trachomatis was discovered by scientists, chylamydia is a bacterial infection that has been said to have plagued the world for hundreds of years prior to its discovery according to The University of Oregon. Chylamydia is the most common bacterial sexually transmitted infection (STI) in the United States, surpassing gonorrhea infection with an estimated 4 million to 5 million reported cases annually to the CDC. The purpose of this study was to describe the prevelance of and risk associated with Chlamydia infection among women aged 15 to 24 . Specifically those who reported engaging in same sex behavior and attended family planning clinics in the Pacific Northwest from 1997 to 2005. This study is of great significance because “according to the 2002 National Survey of Family Growth ,11% of US women aged to 44 years reported same-sex behavior in their lifetime”( Singh et al. 2011).[1] In the Perspective On Sexual and Reproductive Health Journal there was an article published “Gonorrhea and Chlamydia Infection among Women Visiting Family Planning Clinics: Racial Variation in Prevalence and Predictors” that examined the disproportional infection rate of black women vs. that of white...

...Running head: CHLAMYDIA Chlamydia Case Study with Questions Chlamydia “The bacterial infection chlamydia trachomatis is one of the most common sexually transmitted infections (STI). The Chlamydia bacterium can infect the cervix, fallopian tubes, throat, anus and male urethra”. (Henning, D., Alice, R., Sanci, L., Dunning. T., 2006) Chlamydiae are obligate intracellular organisms from bacteria that now comprise 3 species. “They include the following: Chlamydia trachomatis, Chlamydia psittaci, and Chlamydia pneumoniae.” (Bashour, 2007) It is a kind of bacteria that can infect the penis, vagina, cervix, anus, urethra, eye, or throat. Chlamydia is the name of several types of bacteria. One strain occurs primarily in the tropics and causes lymphogranuloma venerum – symptoms include skin lesions and swelling of certain glands in the genital area. According to Kirkland (2006), it is stated that an estimated 2.8 million cases of Chlamydia are reported in the United States each year. It is also mentioned that according to the CDC, there is an increase of more than 60% of Chlamydia cases undiagnosed and untreated. This percentage remains higher among females 15 to 19 and 20 to 24 years of age. Chlamydia can be transmitted during vaginal, anal or oral sex. Chlamydia can also be passed from an infected mother to her baby during vaginal childbirth. Since Chlamydia is known as a silent disease because about three quarters of infected...

...Chlamydia Chlamydia is one of the most common diseases in the United States. The infection is part of a 'silent epidemic' as most cases do not show symptoms and are left untreated. It can cause pelvic inflammatory disease and lead to scarring of the Fallopian tubes causing infertility and higher risk of ectopic pregnancy. The research was carried out at the Molecular Microbiology Group, at the University of Southampton, in conjunction with the Department of Virology, at the Ben Gurion University of the Negev, in Israel. Professor Ian Clarke, from the University of Southampton, says: "This is a very significant advance in the study of chlamydia and we are proud to be the first people to achieve this. "Previously people have been unable to study chlamydial genetics and this has created a barrier to the comprehensive study of this disease. "We, together with our colleagues in Israel, discovered that by treating the chlamydia with calcium ions we were able to introduce a piece of foreign DNA. "This will open up the field of chlamydia research and will enable a better understanding of chlamydial genetics. It could lead to the development of new approaches to chlamydial vaccines and therapeutic interventions." To prove that they had accessed the chlamydial genome, the research team inserted the gene for a fluorescent protein into C. trachomatis which identified the chlamydial-infected cells by making them glow green. Their paper detailing the breakthrough in the study of chlamydia...

...Chlamydia is classified as bacteria, but despite being obligate intracellular organisms that lack mitochondria do not produce their own energy and depend on the host cell metabolism. Chlamydia affects both men and women. Usually, people often have no symptoms or they are mild, making complications associated with the disease, can occur without being aware of the problem. Some of these complications may be irreversible, such as infertility in women. History of the disease: Chlamydia is the most common bacterial sexually transmitted diseases in the United States. It is estimated that around 92 million chlamydia infections occurred worldwide in 1999, affecting more women approximately 50 million than men 42 million. Prevalence of chlamydia fluctuates...

...mother to baby during vaginal delivery, if the mother is affected. Men usually have no symptoms, although infrequently they may have pain when urinating, swollen testicles and/or discharge from the penis. According to a Study completed by the European Journal of Obstetrics and Gynecology, it was discovered that 15% of male infertility are caused by bacteria, parasites or viruses. These infections affect the testicles, the epididymis (a reservoir where the sperm is collected after it leaves the testicles), and the production of male sex hormones. If a woman has a partner that has been diagnosed with a low sperm count, this might have originated from a urinary tract infection or a previous infection of venereal disease. Sperm themselves can also be affected since micro-organisms can affect their development, maturation and motility (how they swim). Another common type of urinary infection is from Escherichia Coli (E-coli). The e-coli bug grows in the intestines of humans and is usually good for you. They are part of the immune system as well as being responsible for the production of a type of vitamin K, which helps with the coagulation of blood; the e-coli bacteria prevent pathogenic infections by eating the bad bacteria in the gut. In many cases, too many e-coli multiply and they can spill out of the intestinal tract and end up clinging to the urethra (the tube which carries urine from the bladder to the outside of the body) and infect...

...Case Study: Ectopic Pregnancy A 28 year old female patient whom is about 8 weeks pregnant was rushed to the ER (Emergency Room) after noticing some vaginal spotting. She also had two abortions in the past 3 years. The patient has been diagnosed and treated for gonorrhea and chlamydia once. She’s been having chills throughout the night but no fever. Some nausea and vomiting was reported. Her weight is at 110 lbs and her BP (Blood Pressure) is 97/54 mmHg. She complained about cloudy urine and pain after urination. She was treated for recurrent UTI (Urinary Tract Infection) and bacterial vaginosis. The RN (Register Nurse) had her to take a urine test, draw blood and orders a CBC (Complete Blood Work) and following up with a pelvic exam. The examination revealed normal external genitalia. The patient was diagnosis for different test to rule out any UTI, GTI (Genital Tract Infection), Ectopic pregnancy, and normal pregnancy. The doctor ordered an ultrasound exam. Her hCG (Human Chorionic Gonadotropin) was at 15,900 mUI/mL. The radiologist reported the patient’s ultrasound shows a thickened endometrium and slightly enlarged uterus. The result shows increased vascularity adjacent in the right ovary while the left ovary was normal. The doctor rushed in the room and told the patient that ectopic pregnancy was suspected. After being rushed in the surgery room, they prepare the patient for surgery. During the diagnostic laparoscopy, a corneal pregnancy was noted on the left side. They removed...

...What is Sexually Transmitted Disease? What are the Common Sexually transmitted diseases? What are the Cause of Each Sexually Transmitted Diseases? What are the signs/symptoms and Diagnosis? What is the complications? What is the Effect of sexually transmitted disease? \ S exually transmitted infection is a broader term than sexually transmitted disease. An infection is a colonization by a parasitic species, which may not cause any adverse effects. In a disease, the infection leads to impaired or abnormal function. In either case, the condition may not exhibit signs or symptoms. Increased understanding of infections like HPV, which infects most sexually active individuals but cause disease in only a few has led to increased use of the term STI. Public health officials originally introduced the term sexually transmitted infection, which clinicians are increasingly using alongside the term sexually transmitted disease in order to distinguish it from the former. STD may refer only to infections that are causing diseases, or it may be used more loosely as a synonym for STI. Most of the time, people do not know that they are infected with an STI until they are tested or start showing symptoms of disease. Moreover, the term sexually transmissible disease is sometimes used since it is less restrictive in consideration of other factors or means of transmission. For instance, meningitis is transmissible by means of sexual contact but is not labeled as an STI...

...pain. STIs acquired before or during birth may result in poor outcomes for the baby. Some STIs may cause problems with the ability to get pregnant.[1] More than 30 different bacteria, viruses, and parasites can cause STIs.[1] Bacterial STIs include chlamydia, gonorrhea, and syphilis among others. Viral STIs include genital herpes, HIV/AIDS, and genital warts among others. Parasitic STIs include trichomoniasis among others. While usually spread by sex, some STIs can also be spread by non-sexual contact with contaminated blood and tissues, breastfeeding, or during childbirth.[1] STI diagnostic tests are easily available in the developed world, but this is often not the case in the developing world.[1] The most effective way of preventing STIs is by not having sex.[4] Some vaccinations may also decrease the risk of certain infections including hepatitis B and some types of HPV.[4] Safer sex practices such as use of condoms, having a smaller number of sexual partners, and being in a relationship where each person only has sex with the other also decreases the risk.[1][4] Circumcision in males may be effective to prevent some infections.[1] Most STIs are treatable or curable.[1] Of the most common infections, syphilis, gonorrhea, chlamydia, trichomoniasis are curable, while herpes, hepatitis B, HIV/AIDS, and HPV are treatable but not curable.[1] Resistance to certain antibiotics is developing among some...

...Preface A well-developed knowledge of clinical microbiology is critical for the practicing physician in any medical field. Bacteria, viruses, and protozoans have no respect for the distinction between ophthalmology, pediatrics, trauma surgery, or geriatric medicine. As a physician you will be faced daily with the concepts of microbial disease and antimicrobial therapy. Microbiology is one of the few courses where much of the "minutia" is regularly used by the practicing physician. This book attempts to facilitate the learning of microbiology by presenting the information in a clear and entertaining manner brimming with memory aids. Our approach has been to: 4) Create a conceptual, organized approach to the organisms studied so the student relies less on memory and more on logical pathophysiology. The text has been updated to include current information on rapidly developing topics, such as HIV and AIDS (vaccine efforts and all the new anti-HIV medications), Ebola virus, Hantavirus, E. coli outbreaks, Mad Cow Disease, and brand-new antimicrobial antibiotics. The mnemonics and cartoons in this book do not intend disrespect for any particular patient population or racial or ethnic group but are solely presented as memory devices to assist in the learning of a complex and important medical subject. We welcome suggestions for future editions. 1) Write in a conversational style for rapid assimilation. 2) Include numerous figures serving as "visual memory tools" and summary charts...
