Herpes zoster

( Shingles)

Shingles is a skin rash caused by the same virus that causes chickenpox. The virus responsible for these conditions is called the Varicella zoster virus (VZV). After an individual has chickenpox, this virus lives in the nervous system and is never fully cleared from the body.

Herpes Simplex

(HSV)

Herpes is an infection that is caused by a herpes simplex virus (HSV). Oral herpes causes cold sores around the mouth or face. Genital herpes affects the genitals, buttocks or anal area. Genital herpes is a sexually transmitted disease (STD). You can get it from having sex, even oral sex. The virus can spread even when sores are not present. Mothers can also infect their babies during childbirth.

B-Virus

B-Virus

Cercopithecine Herpesvirus-1, also known as B-Virus, is a member of the herpes group of viruses that occurs naturally in Macaque monkeys and possible in other Old World monkeys. Infection with B-Virus produces very mild disease in the monkey. Most have no obvious evidence of infection. Some monkeys may have vesicles (small blisters) which progress to ulcers in the mouth, on the face, lips, or genitals and/or eye. These lesions spontaneously heal after a few days, but the virus resides permanently in the monkey, and may reactivate and cause ulcerative lesions periodically. These relapses are especially likely to occur when the monkey is "stressed" (like cold sores or fever blisters in humans). During these periods, the virus is shed by the monkey to the environment. However, the virus may also be shed by monkeys without visible lesions or symptoms.

Enterobacter

Enterobacter

Enterobacter is a genus of common Gram-negative, facultatively-anaerobic, rod-shaped bacteria of the family Enterobacteriaceae. Several strains of the these bacteria are pathogenic and cause opportunistic infections in immunocompromised (usually hospitalized) hosts. The urinary and respiratory tract are the most common sites of infection. Enterobacter can be distinguished from other GNR by virtue of being a ‘fast fermenter’ of lactose (as are Escherichia coli and Klebsiella). Two clinically-important species from this genus are E. aerogenes and E. cloacae.

Chronic Kidney Disease (CKD):

Chronic Kidney Disease (CKD):

Chronic Kidney Disease (CKD): Chronic kidney disease includes conditions that damage your kidneys and decrease their ability to keep you healthy by doing the jobs listed. If kidney disease gets worse, wastes can build to high levels in your blood and make you feel sick. You may develop complications like high blood pressure, anemia (low blood count), weak bones, poor nutritional health and nerve damage. Also, kidney disease increases your risk of having heart and blood vessel disease. These problems may happen slowly over a long period of time. Chronic kidney disease may be caused by diabetes, high blood pressure and other disorders. Early detection and treatment can often keep chronic kidney disease from getting worse. When kidney disease progresses, it may eventually lead to kidney failure, which requires dialysis or a kidney transplant to maintain life.

Gas Gangrene

 

A variety of species of clostridium are associated with invasive infection in humans i.e. C. perfringens, novyi, septicum, histolyticum, tertium, bifermentans, sporogenes. They are not highly pathogenic when introduced into healthy tissues; but in the presence of tissue injury, in particular damaged muscle, they can cause a rapidly progressive devastating infection characterised by the accumulation of gas and the extensive destruction of muscle and connective tissue. Pathogenesis is due to the production of various toxins with necrotising, haemolytic or other destructive properties.

Corynebacterium infections

corynebacterium infections are gram-positive, catalase-positive, aerobic or facultatively anaerobic, generally nonmotile rods. The genus is composed of the species Corynebacterium diphtheriae and the nondiphtherial corynebacteria, collectively referred to as diphtheroids. Nondiphtherial corynebacteria, originally thought to be mainly contaminants, recently have been recognized as pathogenic, especially in immunocompromised hosts.

Cholera is an acute, diarrheal illness caused by infection of the intestine with the bacterium Vibrio cholerae. The infection is often mild or without symptoms, but sometimes can be severe.

Cellulitis

Cellulitis is a spreading bacterial infection of the skin and tissues beneath the skin. Cellulitis usually begins as a small area of tenderness, swelling, and redness. As this red area begins to enlarge, the person may develop a fever—sometimes with chills and sweats—and swollen lymph nodes ("swollen glands") near the area of infected skin.
