3 different types of bacteria

Also referred to as atypical pneumonia, walking pneumonia which health patient from diagnosis must not be hospitalized or bedridden. In contrast to normal or more often pneumonia patient in walking pneumonia is still mobile and move freely, despite the diagnosis of disease. Walking pneumonia resulting from infection of an organism called mycoplasma pneumonia, which consists of certain bacteria, viruses and other chemicals. In the beginning, walking pneumonia cause symptoms similar to colds and other respiratory infections. Some children will have a headache, congestion in the nose, and to report fatigue. Some also experience pain in the throat and even mild fever. The main difference between walking pneumonia and a cold that cold, usually improve or disappear within two weeks or less, but pneumonia symptoms will worsen walking within two weeks, and your child may develop a dry cough or heavy wet cough. Sleeping comfortably is also a problem with your child's cough may get worse during the night. Children may also face a different set of symptoms than in adults with walking pneumonia. Some children may show skin rash, or may experience nausea, diarrhea and vomiting. Children may also experience difficulty in breathing or have a fever and swollen tonsils. Despite the seemingly mild nature of disease, respiratory disease should always be addressed immediately. Abdominal pain and pain in the eyes, ears, chest and muscles


If left untreated, symptoms of pneumonia walking will be stored and can create a dry cough. There are some patients who are able to recover from the infection without treatment, but in other cases, conditions may worsen. Once signs and symptoms of pneumonia walking set, you should immediately seek medical attention. Most cases of pneumonia walking easily treated with certain types of antibiotics. These drugs can speed up recovery. Your advice pediatricians should strictly adhere to particular medication. Cough medicine can be prescribed to treat certain symptoms. Walking pneumonia is actually a contagious disease. It can be transmitted from patient to healthy person by direct contact. The primary means by which the disease can be transmitted from person to person by airborne droplets. Airborne droplets of liquid that comes out of your mouth and nose, also known as secretions from the respiratory tract. These drops may pass to another person through sneezing strattera side effects, laughing, coughing or talking. If your child shows symptoms of pneumonia walking or you suspect that it cold be something more serious, take your child to the pediatrician immediately for care and treatment. It's always better safe than sorry when receiving medical care for any illness your child. .

Researchers looked at a nationally representative ...

suppurative pneumonia

(Reuters) - Pediatricians in the U.S. to write more than 10 million unnecessary antibiotics each year on conditions such as flu and asthma, contribute to a potentially dangerous drug resistance, according to a study. Researchers looked at a national representative sample of nearly 65,000 outpatient visits to children under 18 in 2006 to 2008, the results presented in the journal Pediatrics. In general, physicians prescribed antibiotics in one out of every five visits, while most do for children with respiratory illnesses such as sinus infections and pneumonia. Some of these infections caused by bacteria that require antibiotics. But almost a quarter of all antibiotics were given to children with respiratory diseases, probably or definitely does not require antibiotics, such as bronchitis, influenza, asthma and allergy. This means more than 10 million antibiotics each year, most likely will not bring any benefit, but may hurt, says study leader Adam Gersh at the University of Utah in Salt Lake City. "One reason is excessive because the diagnosis is often not clear -. This is common with ear infections decision to appoint an antibiotic, although the diagnosis is uncertain, just to be on the safe side, "he said. Half of all antibiotics were intended "broad spectrum" drugs that act against a wide range of bacteria - kill some beneficial bacteria in the body, as well as possibly setting a child for more serious infections of antibiotic-resistant bacteria later. "Antibiotics are wonderful. There are times when you really need, the only question to be smart about when we use them, "said Betsy Foxman, Epidemiologist University of Michigan School of Public Health in Ann Arbor, who was not involved in the study. In addition, giving antibiotics to children when they are not needed increases the risk of antibiotic-resistant infections and the children themselves and society as a whole, she said. "We believe that antibiotics are useful as well, but they are not very specific, they affect everything in your body. Making our germs to be us away, we can cause other health problems, we do not know about. "


And to avoid over-prescription? Hersh said that one way might just wait a few days and check the child. "If the diagnosis is still a little unclear strattera prescription, ask if it is safe to wait a day or two with friends to watch, not to start antibiotic immediately," he added. Source:

But the role of bacteria as destroyers ...

2b. Bacteria: Good, bad, evil and >> << Have you ever seen dead dinosaurs in your area? Why not? The land formerly covered them. They should be everywhere. There are no dead dinosaurs around partly because bacteria destroyers, which feed on dead plants or animals. Tissue dead organisms are divided into nitrogen-and carbon-molecules. Decomposed animals can be quite rude! But next time you see a dead bird or squirrel, carefully look at it. Then check it again in about a month. There will be nothing left but bones. And that's what happened to the dinosaurs. Well ... Bacteria use some molecule dead body as food, but the rest of the molecule lost in the soil for plants to use for their growth. Different species feed on plants, to build cells for themselves until they die. Then the cycle repeats as bacteria decompose animals. That's why bacteria are so important for life on Earth. Without them, plants and animals could not get the nutrients they require to survive. But the role of bacteria as destroyers not only because people need them around. Most bacteria are harmless and offers useful features live and humanity. Some bacteria such as Escherichia coli


live in the intestines of animals and people to help them digest food and produce vitamins. Other animals (including cows, goats, deer and giraffes) depend even more than people on bacteria to digest food. Billions of them live in the rumens of animals (a special type of stomach), where they break down grass and hay into nutrients the animal can absorb into your blood. The sample from the cow rumen, for example, includes all types of eubacteria, including the spirochete (spiral bacteria) and several species of bacilliform bacteria. Plants also depend on bacteria to help them absorb nutrients into their roots. Plants need nitrogen to build proteins, but atmospheric nitrogen (which is 78% air) can not be used because of its chemical properties. In the soil, and even in native plants most bacteria help convert atmospheric nitrogen into protein. For example, ryzobiy live in the roots of legumes such as peas, clover, and peanuts. Ryzobiy change nitrogen into nitrogen compounds (such as nitrates and ammonia) that plants and then convert into proteins. Ryzobiy bacteria and leguminous plants living in relationships


This means that everyone benefits from living together. The plant uses nitrogen compounds in bacteria for protein and bacteria gets food from plants. Together, these bacteria are called bacteria


also used in many commercial and industrial applications. Bacteria are used all the time in the food industry. Yogurt is not sharp, without the help of bacteria is called


Lactobacillus acidophillus. Yogurt with milk. Lactobacillus strains devour milk, rich type of sugar called lactose, as well as acid production process, which makes yogurt sour. Acid in yogurt can help save it, because the acidity makes yogurt, bad for the other bacteria. The benefits are endless bacteria. One type of bacteria eats oil and is used to help clean up oil spills. Sewage plants use bacteria to clean water. And all other bacteria are a source of essential medicines such as antibiotics. Poor ... So what bad bacteria? The bad news is that sometimes bacteria cause diseases of plants and animals sick and even kill them. Pathogenic bacteria can infect organisms in two different ways. Most cells attack the body itself. Other produce chemicals called


Anthrax is a deadly type of bacteria that infects animals, especially cattle and sheep. Plants can be infected as well as a number of dangerous bacteria. Care is a bacterial disease of plants, which occurs in apple trees and pear .... , Evil >> << People also have to deal with bacterial diseases on a daily basis. Worldwide, hundreds of thousands of people every year die from bacterial infections that can penetrate the body in several ways. Some bacteria enter the body through the intestines. This occurs when eating or drinking contaminated food or liquids. Cholera, for example, a disease caused by bacteria in unsanitary water. Food poisoning caused by eating contaminated by bacteria such as salmonella and


E.coli. Other bacteria enter the body through the lungs. Tuberculosis and pneumonia caused by breathing the air of bacteria. Bacteria may also enter into the body of stab wounds (eg, tetanus) or insect or animal bites and cause different diseases. One of the most ugly episodes in human history has been associated with bacillary bacterium Yersinia plague is called, otherwise known as bubonic plague or Black Death (so named because of dark color on the face of the victim after death). During the 14th century, this tiny organism millions of people died, more than half the population of Europe. Transmitted by the bite of fleas, the plague has spread across the continent, flea-carriers of animals such as mice and rats strattera 25mg. Even now, bubonic plague still occurs in some parts of the world. But it is treatable with antibiotics and does not cause massive epidemics before. However, something else more sinister lurking in the environment. Today, they cause some of the worst diseases known people, including AIDS. These viruses! However, scientists have not even sure they are alive. How do I stop them? Life on Earth needed bacteria, viruses, but we need? | | | | | | | | | | | | | | Copyright 2007 Apex Learning Inc.

Rejecting the advice of a doctor to go ahead...

Insignificant league pitcher in his youth, Richard Armbruster continued to play baseball and recreation in 70 years, until his right hip began to bother him. In February last year he went to St. Louis hospital for what should have been planned replacement hip joint. In late March, Mr. Armbruster, then 78, was dead. After a series of postoperative complications, the last shot was blood infection that sent him into shock and resistance to treatment. Never in the wildest dreams I think my dad went in for hip joint and be dead in two months, said Amy Fix, one of his daughters. Not until the day Mr. Armbruster died or laboratory culture to identify the organism that infected him: Acinetobacter baumannii. Rostock is one of the categories of bacteria, which by some estimates, has killed tens of thousands of hospital patients every year. While the body does not get as much attention as one known as


methicillin-resistant staphylococcus gold of some infectious disease specialists say they can turn into a big threat. This is because there are several drugs, including approved in the last few years that can treat MRSA. But the combination of business considerations and scientific problems, the industry


holds very little drugs for Acinetobacter and other organisms of the type known as gram-negative bacteria. However, microbes develop and become increasingly resistant to existing antibiotics. In many ways it is much worse than MRSA, said Dr. Louis B. Rice, infectious diseases specialist at Cleveland Louis Stokes VA Medical Center and Case Western Reserve University. There are strains out there, and they become more and more common, are resistant to antibiotics almost everything we have. Bacteria classified as gram-negative, so that their reaction to the so-called Gram test, can lead to serious >> << and urinary tract infections, blood and other body parts. Their cell structure makes them more difficult to attack with antibiotics than Gram-positive bacteria, as MRSA. Acinetobacter, which killed Mr. Armbruster, came to him wide attention a few years ago infection soldiers wounded in Iraq. Meanwhile, in New York, perhaps because of the large number of patients to whom they belong, have become global stage for other drug-resistant Gram-negative germ, Klebsiella pneumonia. According to researchers at SUNY Downstate Medical Center, over 20 percent of Klebsiella infections in hospitals in Brooklyn are now resistant to virtually all modern antibiotics. And they, supergerms now spread worldwide. Health authorities are not good indicators of how many infections and deaths in the United States caused by gram-negative bacteria.


Considers that approximately 1. 7000000 hospital-associated infections of all types of bacteria combined, cause or contribute to 99,000 deaths per year. But in Europe, where hospital surveys have been conducted, Gram-negative infections is estimated to comprise two-thirds of the 25,000 deaths per year caused some of the most problematic nosocomial infections, according to the report published in September by health authorities. It should be noted that MRSA is the most common source of infection. This is especially feared because it can also infect people outside the hospital. There have been serious, even fatal, infections >> << and. In comparison, drug-resistant Gram-negative germs usually only threaten hospitalized patients whose immune system is weak. Microbes can survive for a long time on surfaces in hospitals, and enter the body through wounds, catheters and ventilators. The most alarming of gram-negative is not their frequency but their strattera without prescritpion drug resistance. For gram-positive, we need better drugs for gram-negative we need any medication, said Dr. Brad Spellberg, infectious disease specialist Harbor


Medical Center in Torrance, California, and author, The book is about drug-resistant pathogens. Dr. Spellberg is a consultant to some antibiotics companies and co-founder of two companies operating in other antimicrobial approaches. Condoleezza Rice Cleveland was also a consultant of some pharmaceutical companies. Physicians treating resistant strains of Gram-negative bacteria are often forced to rely on two similar antibiotics developed in the 1940s and polymyxin B. kolistyn These drugs were largely abandoned decades ago because they can lead to kidney and nerve damage, but because they were not used much, bacteria were not likely to develop resistance to them yet. You really had no choice, said Dr. Azza Elemam, infectious disease specialist in Louisville, Kentucky If a person has a life-threatening infection, you should take the risk of injury in the kidney. Such a compromise before Kimberly Dozier, Correspondent CBS News, who developed Acinetobacter infection after injury in a car bomb explosion in 2006, while on mission in Iraq. After two weeks on kolistyn, Ms. Doziers kidneys began to sit, she said in her book. Rejecting the advice of a doctor to go ahead and look for Ms. Dozier stopped taking antibiotics to save her kidneys. Eventually she recovered from the infection. Even this terrible trade-off may not be available for some patients. Last year, doctors in St-Vincents Hospital in Manhattan published an article describing two cases of pan-resistant Klebsiella, incurable kidney, even harmful to older antibiotics. One patient died and one recovered on its own initiative, after antibiotics were stopped. It is rare for doctors in the developed world, the patient died of overwhelming infection, there is no therapeutic opportunities


in the journal Clinical Infectious Diseases. In some cases, resistance to antibiotics extends to Gram-negative bacteria that can infect people outside the hospital. Sabiha Khan, 66, went to the emergency hospital in Chicago New Year's Day suffering from urinary tract and


caused by Escherichia coli resistant to conventional antibiotics. Instead sent home to take pills, Ms. Khan had to stay in the hospital 11 days to get a powerful intravenous antibiotics. This month, the infection returned, sending her back to hospital for an additional two weeks. Some groups of patients say hospital propaganda should take better measures to prevent such infections as ensure that health workers wash their hands frequently and disinfect surfaces and instruments. And antibiotics should not be abused, they say, because it contributes to the development of resistance. To encourage prevention, Atlanta couple, Armando and Victoria Nahum


started after 27-year-old son, Joshua, died of nosocomial infection in October 2006. Jesus, skydiving instructor in Colorado, a broken skull and femur hard landing. During treatment, he twice acquired MRSA, and was infected with Enterobacter Aeho ^ epez, gram-negative bacteria. MRSA they got rid of with antibiotics, said Mr. Nahum. But, they just could not do anything with it. .

Key Q & A How do I know if I want my health professional? Pay attention to your body. If you experience symptoms such as changes in color and consistency of vaginal fluid, genital itching or burning, you may have a vaginal infection which if left untreated, can lead to health complications. What makes bacterial vaginosis (BV) serious consequences for women who are pregnant? Studies have shown that women with untreated BV have a higher risk of having premature or low birth weight baby. Not all vaginal infections cause pregnancy problems, but BV is potentially serious and require attention. Screening strattera cost and treatment

suitable for pregnant women with symptoms of BV. The following measures may be needed during pregnancy. Do all pregnant women receiving treatment for BV? No. Regardless of other risk factors for preterm delivery, all pregnant women with BV who have symptoms should be treated. However, treatment of pregnant women with a positive response to BV, but who


have no symptoms (asymptomatic), is controversial. Generally, pregnant women with asymptomatic BV does not require treatment. What are my chances of BV return? As many as 30 percent of women treated for recurrent BV experience within 90 days of treatment. Do not handle your prescribed medicines could lead to relapse. Why excessive douching increases the risk of BV? Healthy ecosystem of the vagina to correct balance of bacteria flora. Nearly 95 percent of the vaginal mucous membrane, which protects against bacteria and other pathogens, are beneficial bacteria called lactobacillus. These bacteria make natural acids, which keep harmful bacteria get out of control. Too much douching can disrupt bacterial balance and lead to infection. What drugs are not effective against BV? Antibiotics are not effective against BV include ampicillin, erythromycin, tetracycline / doxycycline, triple sulfanilamidnye and ciprofloxacin. Also, vaginal creams and suppositories to treat "yeast" (


Candida) infection is left untreated BV. Why is it important to determine what type of vaginitis I have? BV, trichomoniasis and candidiasis (thrush) caused by different pathogens and should be treated differently. Each type of infection requiring specific treatment, and some infections have more than one reason. What about the diagnosis and treatment of BV in men? Organisms that cause BV in women is not known, or remain in the male urethra. Clinical studies have shown that treatment of male partners with antibiotics does not affect a woman's risk of recurrence or response to therapy. .
