Scabies is a disease that dates back at least 2,500 years. It is a disease of the integumentary system that causes rashes and extremely itchy skin. It is spread from skin-to-skin contact and caused by a small mite that burrows into the skin. Scabies affects 300 million people all over the world, every single year. Scabies can cause other problems with the body such as chronic heart and kidney disease. Trying to diagnose scabies can be rather tricky. Even the most experienced of people in the medical profession can have problems determining if there are scabies mites in a patient’s skin. A negative result does not necessarily mean that a patient does not have scabies. There is no definite test for scabies, doctors just have to base their
After the end of the experiment the unknown 10 sample was Staphylococcus epidermidis. Came to this conclusion by first beginning with a Gram Stain test. By doing this test it would be easier to determine which route to take on the man made flow chart. Gram positive and gram negative bacteria have a set of different tests to help determine the unknown bacterium. Based on the different tests that were conducted in lab during the semester it was determined that the blood agar, MSA, and catalase test are used for gram positive bacteria while Macconkey, EMB, TSI, and citrate tests are used for gram negative bacteria. The results of the gram stain test were cocci and purple. This indicated that the unknown bacteria were gram positive. The gram stain test eliminated Escherichia coli, Klebsiella pneumonia, Salmonella enterica, and Yersinia enterocolitica as choices because these bacteria are gram negative. Next a Blood Agar plate was used because in order to do a MSA or a Catalase test there needs to be a colony of the bacteria. The result of the Blood Agar plate was nonhemolytic. This indicated that there was no lysis of red blood cells. By looking at the plate there was no change in the medium. Next an MSA test was done and the results showed that there was growth but no color change. This illustrates that the unkown bacteria could tolerate high salt concentration but not ferment mannitol. The MSA plate eliminated Streptococcus pneumonia and Streptococcus pyogenes as choices since the bacteria can’t grow in high salt concentration. Staphylococcus aureus could be eliminated because not only did the unknown bacteria grow but also it didn’t change color to yellow. Lastly a Catalase test was done by taking a colony from the Blood Agar plate...
Most people in the U.S. learn STDs in their health class in high school. Syphilis is a sexually transmitted disease (STD) that causes sores over private parts or all over the body in a later stage. Syphilis is caused by a bacteria called spirochete. The spirochete cannot survive outside the body. The only way to get the disease is by intimate contact, but catching it is rare. Having more than one partner could increase the chances to catch the disease. The spirochete enters in a break in your skin genitals area or mouth. Once in your body, about three weeks it becomes a sore or have multiple sores. The sore looks like a crater on the surface of the skin. In the first stage it can be treated easily with antibiotics or penicillin. The second stage the syphilis spreads to the rest of the body. It is visible in your hand and soles on your feet. It can cause cardio-vascular disease, mental problems, paralysis, blindness and tumors. Syphilis has links to HIV/AIDS. It also attacks your nervous system. After infection it takes 21 to develop any symptoms for other people it takes from 10 to ninety days. It acts like no other disease known. The last stage is the deadliest if ignored, by the person. The damage obtained by syphilis is irreversible. By practicing safe sex (condoms), or having one sex partner can prevent these
Clinical Manifestation: Unlike pubic lice, the symptoms of scabies are not easily visible. If there so happens to be symptoms, they may include: severe itching that usually occurs at night, dirty looking small bumps or rashes that a...
If having dry skin isn’t bad enough, witnessing it in front of you get into clumps and morphing into a patch of dry skin most be the worst. Ichtyosis Vulgaris (or also called fish scale disease) is a skin disorder that is passed down the family line that leads to dry, scaly skin. Ichtyosis Vulgaris is one type of skin disorder that is very common. You are born with this skin disease which it is inherited in an autosomal dominant pattern. This type of skin disease is not life threating at all but there really isn’t a way to cure it at you just have to go on living with it. They symptoms of Ichtyosis Vulgaris are: dry skin, scaly skin, mild itching of the skin, and maybe some skin thickening. With time the dry skin can actually begin to bunch up together and start to create patches on your skin covering large areas of your body such as the back, arms, and legs. Unless spotted at a young age most cases of Ichtyosis Vulgaris go undiagnosed due people thinking that it is only “dry skin”
T. vaginalis is a pear-shaped organism that moves itself with four whip-like flagellas that protrude from its front end. A fifth flagellum attached to a flowing membrane that extends rearward. T. vaginalis is a non civilized eukaryotic organism that is in most respects similar to other eukaryotes, but its energy metabolism bears a stronger resemblance to that of anaerobic bacteria. Trichomoniasis is a very common sexually transmitted disease (STD) that is caused by infection with the protozoan parasite called Trichomonas vaginalis. Even though the symptoms of trich varies from host to host , most people who have STI parasite can't tell they are infected. The scientific name is Trichomonas Vaginalis. More common names are trich, vaginitis, ureitis. Trichomonas vaginalis is one of the common sexually transmitted microorganisms in the world, with an estimated 170 million cases occurring each year. The disease is still poorly understood, and some practitioners continue to question its value. However, there is growing evidence that shows that T vaginalis is an important pathogen, in its own right due to the “immediate” morbidity associated with the disease, and more importantly for its role in the promotion of premature rupture of membranes, premature labor, and low birth weight and the likely capability of getting HIV. While a slightly increased risk for HIV (Bowen,2000) transmission may have minor significance for an individual, it may be of considerable value at the community level. T vaginalis was first discovered by Alfred Donne in 1836, when he notice the presence of motile microorganisms in women with frothy vaginal discharge and pruritus. (Beigi,2012) Decades later In the United States, the number of ...
What are these red patches of skin on my body that I can’t ever help from scratching? It is eczema, which is defined as a medical condition in which patches of skin become inflamed, with blisters that cause itching and bleeding. Genetics take a role in the possibility of having eczema, after comes the diagnosis, then being prescribed the treatment needed, and lastly their prognosis.
Even though S. aureus is mainly associated with food poisoning, the bacterium can penetrate the skin or other mucous membranes to invade a range of tissues which will cause a variety of infections. Superficial infection of the skin can cause boils, impetigo, styes (infection of the glands or hair follicles of the eyelids), folliculitis, and furnacles. All of these infections are charac...

This parasite is spread through the bite of sandflies. There are three different types of infections and they each show varying degrees of severity. The cutaneous form produces mild skin ulcers, mucocutaneous produces ulcers in the mouth and nose, and the visceral form of the disease starts with skin ulcers and then fever, low red blood cell count, and an enlarged spleen and liver. The parasite is detected by a microscope and visceral can also be found by doing blood tests. 12 million people are in infected in 98 different countries and 2 million new cases are found every year. The disease also kills around 20 to 50 thousand people a year.

Scabies mites are distributed worldwide, affecting all races, ages and socioeconomic classes in all climates. Sarcoptes scabei, human itch, or mange mites, are in the arthropod class Arachnida, subclass Acari, family Sarcoptidae. These mites burrow under the skin, living in linear burrows. Other races of scabies may cause infestations in other mammals such as domestic cats, dogs, pigs, and horses. It should be noted that races of mites found on other animals could not establish infestations in humans. They may cause temporary itching due to dermatitis but they do not tunnel into the skin.
