This option leads to serious, life-threatening...

Next >> << "Superbug"? Researchers at the University of Buffalo expressed concern at the new, on-recognized, much more powerful version of the common bacteria that appeared in the U.S. "Historically, in Western countries, the classical strains of Klebsiella

pneumonia infection resulted in mainly in patients hospitalized patients receiving missiles at risk, "said Thomas Russo, MD, professor of medicine in the UB School of Medicine and Biomedical Sciences and Head of its Department of Infectious Diseases. "But in the last 10 to 15 years, a new version of this started cause of community acquired infections in young, healthy people," he says. "This option leads to serious, life-threatening, invasive infections and can spread to other organs from the original focus of infection."

Perhaps most important, says Russo, hypervirulent strains of these Klebsiella

pneumonia had the potential to become very resistant to antibiotics like

Escherichia coli and Klebsiella pneumonia classic. "These hypervirulent strains of these" superbakteriy "pending," he says. "If they become resistant to antibiotics, it will be difficult if not impossible to treat."

Given the recent funding from the National Institutes of Health under the program to fund high-risk, high reward research, Rousseau and his UB colleagues study a new variant of Microbiology

Klebsiella pneumonia in an attempt to identify genes that make it hypervirulent so they can figure out how to stop it in its path. "Infections caused by highly resistant bacteria is becoming more problematic," says Russo. "We are constantly threatened with" post-antibiotic "era. The combination of bacteria, which are both high virulence and resistance to antimicrobials is double trouble. " Concerns

research due to the fact that the classical Klebsiella pneumonia is a type of bacteria that can easily buy mobile genetic units called plasmids, which contain several genes that provide a high level of resistance to antimicrobial agents. "In particular, why we are concerned," says Russo. "We know that this bacterium has the potential to acquire these plasmids and that almost certainly will."

He notes that the majority of bacteria that were resistant to the majority of all drugs currently does not usually infect healthy members of the community. "What is alarming about hypervirulent pneumonia Klebsiella, that they have the potential to infect healthy people," says Russo. "If this hypervirulent bacteria become highly resistant to antibiotics, we have significant problems in management. We hope that our study and others may prevent such a possibility. "

Although the new hypervirulent variant was first shown exclusively in the Asia-Pacific region, it has now been found in several North American cities, including Buffalo, and in Europe, Canada, Israel and South Africa. UB researchers describe it as "not recognized" as physicians and microbiology laboratories. The disease usually manifests as liver abscess, which is not typical for healthy patients. "This new option presents unique features and scary: the first is a tendency to infect young, healthy people in society, and the second is its unique susceptibility to metastasis in other parts of the body," says Russo. "This applies to sites outside of the original source of infection, such as the lungs, central nervous system and eyes that can lead to vision loss. If infection spreads to the brain, there can be brain damage as well. From 10 to 30 percent of cases lead to death. "

In Buffalo, is hypervirulent variant >> << Klebsiella pneumonia was found in healthy, young man several years ago. The patient, who strattera no prescritpion was 20 years old, was hospitalized for several months before making a full recovery. These cases concern the entire international community of infectious diseases. Currently, in most cases hypervirulent

Klebsiella pneumonia decide if we consider aggressively with antibiotics and drainage of abscess, however, some infections, despite optimal treatment, resulting in permanent morbidity and death, says Russo. He notes that the potential for error to acquire drug resistance adding urgency to the work. Rousseau says that the microbiological laboratory should be aware that an important characteristic of these hypervirulent strains (also known as hypermucoviscous strains) that the bacterial colonies that grew on solid surfaces in the laboratory reached a common tool of microbiology is called a vaccination cycle, they form a viscous " ; line "more than 5 mm in length. Team Russo at UB now beginning to develop a clear picture of this huge bacterial enemy. In November, he and his colleagues published

PLoS ONE paper, showed that the hypervirulent Klebsiella pneumonia acquires iron more efficiently than conventional strains of K. pneumonia. "With NIH grant, we hope to further clarify the exact details of bacterial factors responsible for the hypervirulent

Klebsiella pneumonia acquisition of iron much more efficiently," he says. "The purpose of this line is that this iron acquisition factors had hypervirulent

Klebsiella pneumonia will themselves as therapeutic vaccines or targets so that we can better treat or prevent infection."

What are the symptoms of bacterial vaginosis?

What is bacterial vaginosis? Bacterial vaginosis is caused byan excessive growth of bacteria (bugs) that are usually present only in the vagina in small numbers. When these bacteria are present in large quantities they can cause symptoms such as abnormal discharge or odor. Bacterial vaginosis is sometimes called nonspecific vaginosis or hardnereloz. What are the symptoms of bacterial vaginosis? There may be an increase in normal vaginal discharge (leaking fluid from the vagina). There may be a strong odor from the vagina and smell can be worse after unprotected intercourse. Some women may not have any symptoms. Other infections may be present at the same time as bacterial vaginosis. It is therefore important to pass tests to exclude sexually transmitted infections as well. How isbacterial vaginosisdiagnosed? During the medical examination the doctor or nurse may notice discharge or odor. The normal acidity of vaginal secretions can be changed to become more alkaline, although a woman may not notice any symptoms. Bacterial vaginosis can be diagnosed easily vaginal swab test. Your test results will be available before you leave the clinic and sexual health doctor may prescribe treatment. How isbacterial vaginosistransmitted? It is not clear whether bacterial vaginosis is sexually transmitted, but is more common in women with more than onesexual partner. It often develops soon after intercourse with a new partner, and it may be associated with other sexually transmitted diseases. It also occurs in women who have sex with other women and it is possible that bacteria can be transferred to the fingers or sex toys. What is the treatment of bacterial vaginosis? If a woman has symptoms, usually no treatment is needed. Treatment should be carried out when a woman has symptoms, or if it is going to be gynecologic procedures (for example, the introduction of the Navy [intrauterine devices] or abortion), which can allow bacteria into the uterus (womb). Treatment is usually antibiotics metronidazole tablets, taken days forseven. Metronidazole can cause nausea and upset stomach, but these effects may be reduced by taking tabletswith food. Do not drink alcohol during treatment or you can get a serious hangover. If you are unable to take metronidazole doctor may prescribe other antibiotics or vaginal creams. May be buy strattera online repeated bacterial vaginosis? Yes. Return of symptoms very often, sometimes for several weeks of treatment. Treatment of male partners of infected women do not seem to prevent recurrences is not recommended. Sometimes the long course of treatment could reduce the return of symptoms. How can bacterial vaginosis be prevented? It is not clear, somewomen yetwhy get bacterial vaginosis. Despite the absence of infection is bacterial vaginosis in men, if you have sex withcasual friends insist thatyour male partner uses a condom. This may reduce the risk of contracting bacterial vaginosis, and protects you against other sexually transmitted diseases.
