Eczema also known as Atopic Dermititis, is a term used for different types of skin swelling. Eczema is an allergic condition that causes red, itchy, swollen skin. Eczema is a chronic disease that can show up on the face, scalp, the creases of the elbows and knees, neck, wrists, or ankles. Eczema is most common in children and babies, as it can occur as early as 2 to 3 months old. It shows up suddenly as a rash that makes the skin feel dry, scaly, and itchy, though itching may come and go.
In the 1920s, Griffith began an experiment that consisted of using two types of pneumonia causing bacteria, smooth and rough. The smooth bacteria that the experiment used had a capsule, while the rough lacked one. Griffith injected the types bacteria into the mice to determine the impact they had. When the mice were injected with live rough bacteria, they lived, and when the mice were injected with live smooth bacteria, they died. Griffith at this point had concluded that the capsule was the cause of death of these mice and he decided to conduct two more experiments.
Lyme disease first became known in 1975 in Lyme, Connecticut when a group of mothers had informed researchers their children all had been identified in having rheumatoid arthritis. This was unusual, and led the researchers to pinpoint the bacterial cause of the children’s illness. It was then in 1982 the condition was given the name “Lyme disease”. In the United States about 300,000 people are diagnosed each year, but because many of the symptoms resemble other diseases it is hard to diagnose and many cases go undiagnosed.
Infection control is very important to minimise cross infection of Micro-organisms. Many micro-organisms are good for us and are essential for life, such as bacteria in the intestine which helps break down food waste matter. However, when a micro-organism is capable of doing harm it is said to be pathogenic. There are four main micro -organisms that cause disease, these include, Viruses, Bacteria, Fungi, and Protozoa. Personal Protective Equipment (P.P.E) can act as a barrier to protect you against infectious material.
Health care associated infections (HAI) are one of the most common issues in hospital settings. These types of infections are not present during hospital administration but instead appear 48-72 hours after hospitalization. Common healthcare associated infections include bloodstream infections, urinary tract infections, pneumonia and surgical site infections. One of the most prevalent of these infections is a urinary catheter associated infection.
ABSTRACT Bacterial conjunctivitis occurs in persons of all races, although differences in frequencies may be reflected by geographical variations of pathogen prevalence. The study was therefore taken up to detect the prevalence of bacterial and fungal pathogens causing occular infections and to study their antibiotic resistant profiles. A total of 44 kerato-conjunctivitis samples were collected, out of which, 31/44 (73%) were fungal isolates . The prevalence of fungal isolates was as follows- 7 Aspergillus fumigatus (22.5%), 3 Aspergillus flavus (9.67%), 4 Aspergillus nidulans (12.9%), 7 Aspergillus niger (22.5%), 10 Fusarium
General Microbiology and Immunology PM204 Rickettsia Name: Khaled Sayed Khalil ID: 141199 Lab Group: B Characteristics: 1- They are naturally obligate intracellular parasites 2- They have the common feature of being spread by arthropod vectors (lice, fleas, mites and ticks) 3- They are rod-shaped or coccoid in nature 4- They range in size from 0.3 to 0.5 micrometer
Introduction: A microorganism is a microscopic living organism which is unicellular or multicellular. Microorganisms interact with human body continuously, but most tionof them do not cause any harm. Only few organisms are pathogenic to human beings. They may be a bacteria, virus, fungus or a parasite. Many of the bacteria are a part of the normal body flora and inhabit various areas in the body such as the oral cavity, nose, skin, nasopharynx, oropharynx, gastrointestinal tract, genitalia, urethra, vagina as well as the external ear.
First and foremost,infection control consideration refers to policies and procedures used to minimize the risk of spreading infections from one person to another especially in hospital or other health care facilities. By and large,we are able to minimize the risk of occurrence infection within the Diagnostic Radiology department by established procedures guidelines in the handling the equipment and awareness of transmission disease throughout the procedure of a radiology examination. Understanding the modes of transmission of infectious organisms and apply the basic protocol of infection prevention and control at all time is important to interrupt the chain of transmission of the bacteria or viruses and minimize the spread of disease among the society. In the first place,due to the routine patient contact in the diagnostic radiology department,any infectious agent transmitted by the contact or droplet route can potentially be transmitted by touch.
The Legionellaceae are thin, aerobic, pleomorphic, flagellated, Gram-negative opportunistic intracellular bacteria. They are non-capsulated rod-like bacterium of approximately 2 μm in length and 0.3-0.9 μm in width. Legionella pneumophila has suggested fastidious nutrient requirements, including ferric iron and L-cysteine. The family Legionellaceae consists of a single genus, Legionella. This genus includes the species Legionella pneumophila, the most frequent cause of human legionellosis and it known as Legionnaires’ disease.
How Long Is Strep Throat Contagious? Strep throat is a bacterial infection caused by Group A streptococcus bacteria. Although only 5 to 10 percent of sore throats are strep throat, up to 15 percent of doctor's visits for a sore throat are due to strep. It takes 2 to 5 days from the time of exposure until symptoms appear.
