NOSOCOMIAL INFECTIONS Nosocomial Infection is an infection that occurs in a hospital of hospital-like setting. Approximately 10% of American hospital patients contract this infection. There are three factors as to why nosocomial infection exists: 1. A high prevalence of pathogens. 2. A high prevalence of compromised hosts. 3. Efficient mechanisms of transmission from patient to patient. These three factors alone lead not just to a higher chance of transmission

People with Ecythma will have painful blisters that may turn into ulcers‚ scars and swollen

Introduction Hepatitis B infection is one of the major and common liver infectious diseases worldwide‚ and caused by a small enveloped DNA virus‚ the hepatitis B virus (HBV). (Tong 2005Int J med Sci) Importantly‚ over 20 million people are infected annually with HBV and there are globally 350-400 million chronic carrier of HBV. (McMahon 2005.) Routes of infection include vertical transmission (through childbirth)‚ early life horizontal transmission (bites‚ lesions‚ and sanitary habits)‚ and adult

Disseminated gonococcal infection is caused by hematogenous infection of N. gonorrhoeae from the primary site of infection. It occurs in both men and women‚ but is seen more frequently in women‚ because women with gonorrhea are often asymptomatic‚ which allows the dissemination of infection before the patient experiences symptoms. Pregnancy‚ menses‚ and terminal component complement deficiencies also increase the risk for disseminated gonococcal infection as a result of endometrial exposure of submucosal

Urinary tract infections refer to the presence of pathogenic microorganisms within the urinary tract and its classification is usually done on the basis of infection sites:-bladder [cystitis]‚ kidney [pyelonephritis]‚ or urine [bacteriuria] and also can be asymptomatic or symptomatic (Quigley R 2009‚ Schlager TA2001). They are among the most commonly acquired bacterial infections and they account for an estimated 25-40% of the nosocomial infections (Bagshaw SM‚ Laupland KB 2006). Urinary tract infection

Causes and spread of infection 1.1: Bacteria are single-celled microorganisms with a simple cellular organization whose nucleus lacks a membrane. Viruses are DNA wrapped in a thin coat of protein that replicates only within the living hosts. Fungi come in many different varieties and we eat quite a few. Mushrooms are fungi as is the mould that forms the blue or green veins in some types of cheese. Yeast is another type of fungi and is the necessary ingredient to make most types of bread.
