Pneumonia is usually cold complications. Although colds can be transmitted from person to person, bacterial pneumonia is not contagious. Pneumonia is a disease that results from infection of the respiratory tract and lungs, some microbes. When a person has pneumonia, lung tissue can fill with pus and other liquids, making it difficult for oxygen in the air bags light to reach the blood. With pneumonia, a person may be shortness of breath and cough and fever are. Sometimes a person may have chest or abdominal pain and nausea, too. This makes it difficult for the patient to breathe properly and can cause death within 3 -4 days if not treated. This affacks mainly children under 5 years old, but adults can also have it. Each year over 60,000 Americans die of pneumonia - pneumonia usually caused by infection with bacteria, viruses, fungi or other organisms. Pneumonia is a particular concern for the elderly and people with chronic illnesses or impaired immune system, but can also affect young, healthy people. Worldwide is the leading cause of death of children, many under the age of the year. About 80% of cases of pneumonia caused by viruses, bacteria and 20%. Viral pneumonia is usually milder than bacterial pneumonia. Bacterial pneumonia in the elderly is often atypical clinical presentation and poor prognosis. Clinical manifestations are often atypical. Fever is recorded only in 58% of cases and extra-respiratory symptoms are common. Pneumococcus and Haemophilus influenzae bacteria are the most common pathogens. Diagnosing pneumonia may be severe in some people, especially those with other diseases. With the advent of modern microbiology, classification based on the causative microorganism became possible. Determine which organism causes pneumonia rights is an important step in determining the type and length of treatment. Sputum, blood cultures, tests on respiratory and specific blood tests to determine the microbiological classification. Because such laboratory testing typically takes several days, microbiologic classification is usually not possible at the time of initial diagnosis. Although antibiotics can treat some of the most common forms of bacterial pneumonia antibiotic-resistant strains growing problem. Many patients arrive in U.S. hospital emergency receiving antibiotics based on federal guidelines for treatment of pneumonia do not need drugs, says a new study. This means that the user may not be feasible and may contribute to the growing problem of antibiotic resistance, the study authors said. Researchers studied in 2004, the main provision that provides that emergency physicians manage antibiotic within four hours in adult patients displaying symptoms of pneumonia. Centers for Medicare and Medicaid Services (CMS) and Joint Commission on Accreditation of Health Organizations (JCAHO) established the direction as the main measure hospital performance. Earlier studies have shown that the use of antibiotics during this time window was associated with a small decrease in mortality. University HealthSystem Consortium is to achieve 90 percent in accordance with management. The University of California, San Francisco, where research was done without physician staff bonuses depend on this show. A study conducted in 2005, after which the group of 152 emergency room patients who met the criteria for receiving antibiotics. Of this group 65. 1 percent received antibiotics within four hours of arrival at hospital. The remaining 34. 9 percent were defined as "emissions", and more than half (58. 5 percent) emissions are not the final diagnosis of pneumonia. And 43 percent of emissions was abnormal chest x-ray, compared with 95 percent of those who received antibiotics. "It was not possible in many cases actually gave them antibiotics because many of them do not actually have pneumonia or got a diagnosis later," said Dr. Jesse Pine, author of the accompanying editorial in the journal, and a doctor in the emergency medical care in the hospital of the University of Pennsylvania. It supports the cheap strattera results of the study. The authors concluded that it may be possible to identify 90 percent of emergency department patients hospitalized with pneumonia using the current JCAHO / CMS case definitions. Or purpose or determining to change, say researchers. Pneumonia is the leading cause of emergency visits, Pine said. Many experts criticize the leadership and research, in which they are based. "I think it is extremely difficult and controversial when CMS and Joint Commission to establish national performance standards based on retrospective, clinically unconfirmed retrospective studies," said Dr. Tareg Bay, Professor of Medical Emergencies and Director of International Emergency Medicine at the University of California in Irvine. "I can easily imagine that this program will lead to increased resistance to antibiotics of bacteria pneumonia just because doctors prescribe antibiotics earlier and more frequently to achieve the objectives of the program CMS." Performance of medicine is fundamentally a good thing, but it should be based on very strong scientific data, "Bay added." Retrospective studies alone, and do not recognize the complex interdependence of our highly stressed health care system is not good enough to link 4:00 a rule to pay for performance program. "


3 beneficial effects of bacteria

Pine said that the leadership can not even solve the basic underlying problem that ambulances crowding." That is why ambulances are so overcrowded, obtain chest x-ray and doing all the things that go for a quick diagnosis of pneumonia is not possible, "he said." What happens to performance measures is that patients with suspected pneumonia end to receive antibiotics before they have a diagnosis in order to meet mandatory state standards. "

Aspiration pneumonia is an inflammatory lung disease that occurs when your dog inhales foreign substances. This often occurs with disorders that cause regurgitation or vomiting. However, neuromuscular disorders that cause difficulty in swallowing or paralysis of the esophagus may lead to aspiration pneumonia. Dogs often so than cats, and depending on the main causes of all ages and breeds suffer. Causes of esophageal disorders such as esophageal obstruction with alien bodies or masses, inflammation of the esophagus, or paralysis and expansion of the esophagus (megaesophagus)


Reducing mentation or alertness causes reduced swallowing reflex induced by general anesthesia, sedation, head trauma, or seizure

exercise tolerance, weakness Diagnosis


thorough physical examination of chest auscultation (listening to the chest by stethoscope) and palpation of the abdomen is very useful to detect changes that may indicate the presence of aspiration pneumonia. Additional tests may include:


Your veterinarian may choose to run some laboratory tests such as complete blood count (CBC), biochemical profile and urinalysis to look for signs of infection and availability reasons. A chest radiograph may show lung abnormalities that may indicate aspiration pneumonia. The liquid can be obtained from the lower airways and lungs to examine under a microscope, and it can be cultivated to isolate the causative bacteria and determine the correct antibiotic use in the treatment. If the animal is in respiratory failure, the blood gas analysis may be considered. Various other tests may be necessary to determine the cause of vomiting, regurgitation or dysfunction. Such tests include abdominal X-rays, X-ray or esophageal barium and fluoroscopy (X-ray video) to evaluate the esophagus in motion. If found, then further testing is indicated to seek the cause of paralysis of the esophagus. Treatment Hospice may need hospitalization with oxygen, intravenous fluids, antibiotics and supportive therapy. Slightly injured pets that are well hydrated and eat right can be treated outpatient with frequent following tests to monitor the progression of infection. Additional treatments may include:


attenuation secretions. This can be done with humidifier or knock the chest wall (blend). Surgery. In some cases, removing the affected lobe of the lung, foreign body or tumor can be done. Home Care and Prevention of aspiration pneumonia, including stomach contents, may be serious, life-threatening condition. Animals may need several days in intensive care before it stabilized, and some animals with great difficulty craps from this condition, especially if the main problem is due to paralysis of the esophagus. Once the animal is discharged from the hospital to administer all medications as directed by veterinarian. Back to the examination, blood tests and X-ray according to the recommendations of the veterinarian. Many times, aspiration pneumonia can not be prevented. However, treatment and control of underlying disease can significantly reduce the risk of aspiration pneumonia or to prevent recurrence of the state. .

Other examples for targeted proteins ...

3 bacteria shapes

Envelope cell wall of gram-positive bacteria, macromolecular, exoskeleton organelles that are collected and submitted in prescribed areas. Cell wall also functions as a surface organelles that allows gram-positive pathogens to interact with the environment, particularly in the tissues of the infected host. All these functions require that surface proteins and enzymes, properly targeted to the cell wall envelope. Two major mechanisms of cell wall sorting and targeting, have been identified. Cell sorting and covalent joining surface proteins peptidoglycan through C-terminal sorting signal that contains a consensus LPXTG sequence. More than 100 proteins with cell wall sorting signals, including the M proteins of Streptococcus pyogenes, Staphylococcus aureus protein, and several internalins of Listeria, were found. Targeting cell wall involves attachment nekovalentnyh proteins on the cell surface via specialized binding domains. Some of these wall-binding domains appear to interact with secondary wall strattera price polymers that are associated with the peptidoglycan, for example teyhoevye acids and polysaccharides. Proteins targeted to the cell surface muralytic include enzymes such as autolysins, and phage lytic lizostafin enzymes. Other examples for targeted proteins surface S-layer proteins of bacteria and clostridia, as well as virulence factors required for pathogenesis monotsytohenes L. (Internalin B) and pneumococcus (PVNS) infection. In this review we examine the mechanisms for sorting proteins to the membrane attack gram-positive bacteria and review the functions of known surface proteins. .
