Staphylococcus Aureus is a gram-positive coccus bacterium found in humans. It is frequently found on the mucus membrane in the nasal cavity and on the skin. It also infects many people in the hospital‚ also called a nosocomial infection. S. aureus has a large association with clinically significant infections and

bacterium because there is very little that is known about it. Though it is not as aggressive as its cousin Staphylococcus aureus‚ Staphylococcus epidermidis is the most frequent cause for nosocomial pathogens‚ especially among newborns‚ the elderly‚ and anyone who has a compromised immune system. These infections are usually associated with intravascular catheters and other indwelling medical devices ("Staphylococcus epidermidis"). S. epidermidis produces a biofilm that grows on medical devices and

A1. Procedure The preoperative procedure of using with chlorhexidine-alcohol (CHG) before surgery has been proven to be more effective to reduce the number of surgical site infections (SSI) than the use of povidone iodine. By reducing the number of infections post surgery‚ it can lower patient morbidity and can reduce hospital stay time and eliminate further unnecessary costs. A2a.

Discussion Questions – Urine 1. The results obtained for this urine sample (U19) shows that the patient is infected with urinary tract infection. This is identified by the high amount of colonies observed on Horse Blood Agar (>108/L)‚ mild amount of protein (30 mg/mL) and very high amount of red blood cells (Large+++) found in the urine. The bacterium identified in this specimen is Pseudomonas aeruginosa. This is confirmed by involving many tests and observation‚ such as Gram stain‚ oxidase test

Adenovirus infection Adenovirus infections most commonly cause illness of the respiratory system; however‚ depending on the infecting serotype‚ they may also cause various other illnesses‚ such as gastroenteritis‚ conjunctivitis‚ cystitis‚ and rash illness. Symptoms of respiratory illness caused by adenovirus infection range from the common cold syndrome to pneumonia‚ croup‚ and bronchitis. Patients with compromised immune systems are especially susceptible to severe complications of adenovirus

Franco Biology 1A Lab Erik Arevalo Parvovirus Parvovirus is one of the smallest eukaryotic viruses that exist. It is a disease that attacks an organism’s cells and can go into the bloodstream‚ allowing other types of illnesses such as subclinical infections‚ dermatologic‚ hematologic‚ and rheumatologic manifestations to attack the body (Cotmore et al.‚ 2013). A key characteristic of parvovirus is that it replicates itself rapidly through an organism’s cells. It is a part of the parvoviridae family

Molecular Characterization of Methicillin-Resistant Staphylococcus aureus (MRSA) Nasal Colonization and Infection Isolates in a Veterans Affairs Hospital Staphylococcus aureus (S. aureus) belongs to the genus Staphylococcus. It is Gram-positive‚ cocci shaped anaerobic bacteria that forms clusters and produces catalase‚ which catalyzes hydrogen peroxide to water and oxygen. It contains a cell wall structure (including peptidoglycan and teichoic acid) and a low G + C content of DNA between 30-40 mol

In order to identify the healthcare professional’s responsibility the author will be drawing from three different sources including documents from the Department of Health‚ the Nursing and Midwifery Council’s code of conduct and the Royal College of Nursing. After this‚ the essay will talk about two different practises that healthcare professionals can use to break the chain of infection. These will include
