About 10% of mrsa infections now ca-mrsa...

From MicrobeWiki, student edited microbiology resource


necrotizing fastsyyt, also known as carnivores disease is a fatal bacterial infection in the deeper layers of skin and refers to tissue death. It destroys soft tissue and can cause damage as


muscles and skin and can cause fatal toxic shock syndrome (TSS) [and there is a wide range of people, and may be executed in different ways. Causes Bacteria cause most cases of necrotic fastsyyt, but there are rare cases where some fungi and cause the same infection. This disease is often caught bacteria coming into contact with open wounds. Bacteria can enter the body through the small opening, such as paper cuts, but can also occur after surgery. Sometimes it can also pass through the area where the skin is weakened, but still intact, as slaughter or blister. Bacteria travel in droplets and in some cases was transmitted from person to person through who were in close contact, through body fluids, such as cough. Necrotizing fastsyyt damage subcutaneous tissue and causes a rapid destruction of fat and fascia and by weakening the immune system and turn off its ability to fight bacterial infections that can cause death if not treated. This disease, which attacks the young and old, healthy and sick people alike. [


Necrotizing fastsyyt can be caused by various bacteria and are divided into three types. Type 1 polymicrobial


bacteria harmful

Type 2 or streptococcus group A;


Type 3 gas gangrene [2]


The most common cause is group A streptococcus, also called "GAS", which typically causes strep throat. This group of bacteria rapidly multiply in the body, rapidly progressing in all this. Other groups of bacteria that can cause necrotizing fastsyyt is Staphylococcus aureus, Vicrio vulnificus, Clostridium perfringens and Bacteroudes brittle. [1], various bacteria usually works well on their way to attack the tissues and reduce the immune response by producing toxins by blocking the mechanism of protection. New bacteria that cause necrotizing fastsyyt was recorded as an increase in the last couple of years. This bacterium called metytsyllyn resistant golden Auerus (MRSA) and is a growing concern because of its resistance to antibiotics. Warning some ways to reduce the risk of getting necrotizing fastsyyt should always wash the wound and small holes in the skin of antibiotic substances and cover your mouth with them while coughing or sneezing and generally avoid contact with people who show symptoms of angina. Symptoms The symptoms appear at different stages, from early usually appear during the first 24 hours. Necrotizing fastsyyt


Early symptoms symptoms develop rapidly throughout the body and can become a critical stage in a short period of time. The first thing people usually show pain in the wound, where is. The pain gradually increased, and the tissue becomes swollen and the skin color may change. This is accompanied by flu-like symptoms such as fever, nausea, weakness and diarrhea. The body becomes gradually more and more dehydrated and the person experiences increased thirst. Additional signs These symptoms usually appear within a few days and include signs of shock, drop in blood pressure that makes people seem crazy or difficulty breathing. Critical symptoms when the body was bacteria within a few days it starts to close. The body feels "toxic shock", which makes the pressure of the blood drop dramatically and can lead to loss of consciousness and multiple organ failure. [1]


Treatment of patients who show signs of necrotizing fastsyyt should be taken to the hospital immediately. Mortality of people who do not receive treatment was measured to be higher than 25%. [2] The first step in treatment is that of surgical treatment, removal of infected tissue to prevent further spread. The patient should be treated with antibiotics immediately stop the spread of disease. Early diagnosis is crucial to the health of patients and can make a significant impact, but doctors often fail to recognize the disease because the symptoms are very similar to those of the chimney. There are several ways to diagnose and detect disease, but X-rays and surgical biopsy is rarely carried out in connection with flue symptoms. One of the most serious threats to the continued spread of necrotizing fastsyyt new Methicilin prevalence of S. auerous (MRSA). The bacterium was unusual cause of disease, but has increased alarmingly in recent years. The emergence of MRSA has become a growing concern and has become one of the most difficult to treat pathogens in hospitals today. The bacteria was first seen in 1961 and has strattera 25mg since mutated and developed resistance to almost all β-lactam antibiotics, which makes the implementation of more aggressive treatment with antibiotics. [5]


Estimates show that there are 2. 3000000 people living in the United States today hosting the bacteria MRSA, but this so-called «Superbug is a common worldwide [9]. The bacteria are reported to account for about 19. 000 people each year throughout the country. [6]. Bacteria can be transmitted through the skin and body fluids contact and indirect contact, such as a form of coins, toys, etc. MRSA causes skin and tissue infections, and skin begins as a small rash, which then develop into an open wound. There are effective antibiotics for treating MRSA in the market, such as rimethoprim-sulfamethoxazole (Bactria), doxycycline and clindamycin, but recent reports suggest that resistance to these antibiotics are now growing rapidly. [9] Some doctors say that simply is not enough developed and tested products available to keep pace with the development of drug-resistant bacteria. The fact that antibiotic-resistant bacteria MRSA causing necrotizing fastsyyt is a serious problem, because the disease damages the tissue quickly and usually treated with antibiotics. MRSA bacteria are also know to cause pneumonia, which intensifies the problem. MRSA, which fell in the hospital is called hospital-related methicillin-resistant staphylococcus gold (MRSA-HA), while MRSA contracted outside a hospital called Community Associated methicillin-resistant staphylococcus gold (CA-MRSA). CA-MRSA refers to people who are infected, even if they are not subjected to the influence of risk factors such as hospitalization or surgery. [7] Despite CA-MRSA spread among the communities currently making its way to the hospital, and further increases the problems MRSA hospital deal. CA-MRSA has shown that often more common among drug addicts, people with HIV or AIDS, and diabetes. [5] About 10% of MRSA infections now CA-MRSA, but only 20% of patients come to hospitals. People infected with CA-MRSA, usually does not face the same risks as men with HA-MRSA, if they are diagnosed early and offer the correct treatment. However, if there are complications they can be more serious because it can cause crashes body, damage the lungs, kidneys and endocarditis. [8] The main difference between the two strains of MRSA is that CA-MRSA contains a powerful toxin leykotsydynu pantones, Valentina, which targets white blood cells, white blood cells used to fight infections. Warning increased resistance. It is important to educate hospital personnel and the general public about the importance of hygiene and disinfection of isolation and encourage infected patients in hospitals. [9] accurate and early diagnosis is necessary to in order to prevent the spread of disease and raising awareness among doctors that the symptoms of attention can help detect infections before they intensify. People who recently treated with antibiotics to high risk if infected with MRSA or necrotizing Fasciiti and is a big debate going now about how excessive and over-prescription of antibiotics should be taken into consideration in this matter. Current prescription of antibiotics, where people with viral infections are treated with antibiotics contributes to resistance and the risk it represents. It is important that antibiotics are used carefully and when considered necessary. [10], the Association of Surgical Technologists (AST), necrotic fastsyyt Valentin Rodriguez.
