14574_lores.jpg | This photomicrograph of a vaginal smear specimen depicts two epithelial cells, a normal cell, and an epithelial cell with its exterior covered by bacteria giving the cell a roughened, stippled appearance known as a “clue cell”. Clue cells are epithelial cells that have had bacteria adhere to their surface, obscuring their borders, and imparting a stippled appearance. The presence of such clue cells is a sign that the patient has bacterial vaginosis. [http://phil.cdc.gov/Phil/ <font size="-2">''Adapted from CDC''</font>]

Bacterial vaginosis02.jpeg | This photograph depicted a single ''Gardnerella vaginalis'', formerly ''Haemophilus vaginalis'', or ''Corynebacterium vaginalis'', bacterial colony. The vagina is normally colonized by ''Lactobacillus'' spp., which help to regulate the region’s pH, maintaining it in the low range, thereby, inhibiting the growth of potentially-pathogenic organisms. The Gram-positive ''Gardnerella vaginalis'' bacterium is one such organism, and is a common cause for bacterial vaginosis (BV). [http://phil.cdc.gov/Phil/ <font size="-2">''Adapted from CDC''</font>]

1048_lores.jpg | Under a relatively-low magnification of 63X, this Gram-stained photomicrograph of a vaginal specimen revealed the presence of squamous epithelial cells, polymorphonuclear leukocytes (PMNs), or white blood cells (WBCs), and numerous Gram-positive bacilli, or rods. Vaginal specimens are reviewed for many reasons including the Pap test, tests for STDs such as human papilloma virus (HPV) and ''Chlamydia trachomatis'', as well as others. The vagina is normally home to a number of bacterial organisms, referred to as vaginal microbiota, or vaginal microflora, composed primarily of rod-shaped ''Lactobacillus'' spp., as well as others.

15564_lores.jpg | Viewed from the right posterior-oblique view, the male patient depicted here was in bed, in a clinical setting, and had presented with a pancorporeal maculopapular rash, which was initially thought to be a possible case of smallpox, but which later, was diagnosed as herpes simplex. Here you see the patient’s feet from a left lateral perspective revealing papules on the dorsal surface of the left foot. Herpes simplex virus, otherwise known as ''Herpesvirus hominis'' is a member of a group of viruses including those which cause oral herpes, i.e., usually HSV-1, and genital herpes, i.e., usually HSV-2. The virus can become disseminated, as was the case here, usually involving patients who are immunocompromised such as in the case of AIDS, or undergoing chemotherapeutic treatment.

14427_lores.jpg | This image depicts the perineal region of a male patient which displayed a perianal mucocutaneous lesion caused by a herpes simplex infection. Genital herpes is a sexually transmitted disease (STD) caused by the herpes simplex viruses type 1 (HSV-1) or type 2 (HSV-2). Most genital herpes is caused by HSV-2. Most individuals have no or only minimal signs or symptoms from HSV-1 or HSV-2 infection. When signs do occur, they typically appear as one or more blisters on or around the genitals or rectum. The blisters break, leaving tender ulcers (sores) that may take two to four weeks to heal the first time they occur. Typically, another outbreak can appear weeks or months after the first, but it almost always is less severe and shorter than the first outbreak. Although the infection can stay in the body indefinitely, the number of outbreaks tends to decrease over a period of years. [http://phil.cdc.gov/Phil/ <font size="-2">''Adapted from CDC''</font>]

6510_lores.jpg | This neonate displayed a maculopapular outbreak on his feet due to congenitally acquired herpes simplex virus. In this instance, due to the age of the patient, this condition is known as herpes simplex neonatorum. See PHIL 15115, for a closer view of these lesions. Genital HSV can cause potentially fatal infections in babies. It is important that women avoid contracting herpes during pregnancy because a first episode during pregnancy causes a greater risk of transmission to the baby. If a woman has active genital herpes at delivery, a cesarean delivery is usually performed. Fortunately, infection of a baby from a woman with herpes infection is rare.[http://phil.cdc.gov/Phil/ <font size="-2">''Adapted from CDC''</font>]

Lice are parasitic insects that can be found on people's heads, and bodies, including the pubic area. Human lice survive by feeding on human blood. Lice found on each area of the body are different from each other. The three types of lice that live on humans are: ''Pediculus humanus capitis'' (head louse), ''Pediculus humanus corporis'' (body louse, clothes louse) and ''Phthirus pubis'' ("crab" louse, pubic louse). Only the body louse is known to spread disease. Lice infestations are spread most commonly by close person-to-person contact. Dogs, cats, and other pets do not play a role in the transmission of human lice. Lice move by crawling; they cannot hop or fly.

Note that the scabies had burrowed into the upper layers of this patient’s skin, into the epidermis, superficial to the stratum basale, also known as the stratum germinativum. The most common signs and symptoms of scabies are intense itching (pruritus), especially at night, and a pimple-like (papular) itchy rash. The itching and rash each may affect much of the body or be limited to common sites such as the wrist, elbow, armpit, webbing between the fingers, nipple, penis, waist, belt-line, and buttocks. The rash also can include tiny blisters (vesicles) and scales. Scratching the rash can cause skin sores; sometimes these sores become infected by bacteria.

However, this form of scabies is mild, and the mites die in a couple of days without reproducing. [http://phil.cdc.gov/Phil/ <font size="-2">''Adapted from CDC''</font>]

15625_lores.jpg | This image depicts the soles of both feet of a syphilis patient revealing the presence of secondary syphilitic lesions consisting of erosive dermal regions of the toes, mainly involving the intertriginous spaces between the toes. Secondary syphilitic lesions consist of skin rashes and/or sores in the mouth, vagina, or anus (also called mucous membrane lesions) mark the secondary stage of symptoms. This stage usually starts with a rash on one or more areas of the body. Rashes associated with secondary syphilis can appear from the time when the primary sore is healing to several weeks after the sore has healed. The rash usually does not cause itching. This rash may appear as rough, red, or reddish brown spots both on the palms of the hands and/or the bottoms of the feet. However, this rash may look different on other parts of the body and can look like rashes caused by other diseases Large, raised, gray or white lesions may develop in warm, moist areas such as the mouth, underarm or groin region. Sometimes rashes associated with secondary syphilis are so faint that they are not noticed. Other symptoms of secondary syphilis include fever, swollen lymph glands, sore throat, patchy hair loss, headaches, weight loss, muscle aches, and fatigue. The symptoms of secondary syphilis will go away with or without treatment. Without appropriate treatment, the infection will progress to the latent and possibly late stages of disease. <br>[http://phil.cdc.gov/Phil/ <font size="-2">''Adapted from CDC''</font>]

15566_lores.jpg | This image depicted the umbilicus of an infant, which displayed an inflamed lesion that under a darkfield examination revealed the presence of Treponema pallidum spirochetes, and hence, a diagnosis of congenital syphilis. Syphilis is a sexually transmitted disease (STD) caused by the bacterium ''Treponema pallidum''. It has often been called "the great imitator" because so many of the signs and symptoms are indistinguishable from those of other diseases. It is passed from person to person through direct contact with a syphilis sore. Sores occur mainly on the external genitals, vagina, anus, or in the rectum. Sores also can occur on the lips and in the mouth. Transmission of the organism occurs during vaginal, anal, or oral sex. Pregnant women with the disease can pass it to the babies they are carrying. Syphilis cannot be spread through contact with toilet seats, doorknobs, swimming pools, hot tubs, bathtubs, shared clothing, or eating utensils.<br>[http://phil.cdc.gov/Phil/ <font size="-2">''Adapted from CDC''</font>]

12605_lores.jpg | This photograph depicts the destruction of a patient’s left knee joint, which was determined to be a case of neuropathic arthropathy, also known as Charcot’s joint, brought on by a tertiary syphilitic infection. See PHIL 12606, for a radiographic view (x-ray) of a patient's knee with this arthritic deformity. Late and Latent Stages: The latent (hidden) stage of syphilis begins when primary and secondary symptoms disappear. Without treatment, the infected person will continue to have syphilis even though there are no signs or symptoms; infection remains in the body. This latent stage can last for years. The late stages of syphilis can develop in about 15% of people who have not been treated for syphilis, and can appear 10-20 years after infection was first acquired. In the late stages of syphilis, the disease may subsequently damage the internal organs, including the brain, nerves, eyes, heart, blood vessels, liver, bones, and joints. Signs and symptoms of the late stage of syphilis include difficulty coordinating muscle movements, paralysis, numbness, gradual blindness, and dementia. This damage may be serious enough to cause death.<br>[http://phil.cdc.gov/Phil/ <font size="-2">''Adapted from CDC''</font>]

12597_lores.jpg | This image depicts the perineal region and upper thighs of an infant born with what was diagnosed as congenital syphilis. In this particular case, one will note the presence of early cutaneous syphilids. How does syphilis affect a pregnant woman and her baby: The syphilis bacterium can infect the baby of a woman during her pregnancy. Depending on how long a pregnant woman has been infected, she may have a high risk of having a stillbirth (a baby born dead) or of giving birth to a baby who dies shortly after birth. An infected baby may be born without signs or symptoms of disease. However, if not treated immediately, the baby may develop serious problems within a few weeks. Untreated babies may become developmentally delayed, have seizures, or die. Infants born to mothers who have reactive nontreponemal and treponemal test results should be evaluated with a quantitative nontreponemal serologic test (RPR or VDRL) performed on infant serum because umbilical cord blood can become contaminated with maternal blood and could yield a false-positive result. Conducting a treponemal test (i.e., TP-PA or FTA-ABS) on a newborn’s serum is not necessary. No commercially available immunoglobulin (IgM) test can be recommended. All infants born to women who have reactive serologic tests for syphilis should be examined thoroughly for evidence of congenital syphilis (e.g., nonimmune hydrops, jaundice, hepatosplenomegaly, rhinitis, skin rash, and/or pseudoparalysis of an extremity). Pathologic examination of the umbilical cord by using specific fluorescent antitreponemal antibody staining is suggested. Darkfield microscopic examination or DFA staining of suspicious lesions or body fluids (e.g., nasal discharge) also should be performed.<br>[http://phil.cdc.gov/Phil/ <font size="-2">''Adapted from CDC''</font>]

Note that some of the rash sparsely included areas of her forearms, as well. The secondary stage of syphilis is characterized by the manifestation of a skin rash and mucous membrane lesions. This stage typically starts with the development of a rash on one or more areas of the body. The rash usually does not cause itching. Rashes associated with secondary syphilis can appear as the chancre is healing or several weeks after the chancre has healed. The characteristic rash of secondary syphilis may appear as rough, red, or reddish brown spots both on the palms of the hands and the bottoms of the feet. However, rashes with a different appearance may occur on other parts of the body, sometimes resembling rashes caused by other diseases. Sometimes rashes associated with secondary syphilis are so faint that they are not noticed. In addition to rashes, symptoms of secondary syphilis may include fever, swollen lymph glands, sore throat, patchy hair loss, headaches, weight loss, muscle aches, and fatigue. The signs and symptoms of secondary syphilis will resolve with or without treatment, but without treatment, the infection will progress to the latent and possibly late stages of disease.<br>[http://phil.cdc.gov/Phil/ <font size="-2">''Adapted from CDC''</font>]
