Untreated strep throat can lead to serious...

Bacteria around us, in the air, on objects and are usually found in and on the human body. When bacteria in the human body in the absence of disease, it is called colonialists. However, people may become infected by pathogenic bacteria from food, water, abrasions and other wounds and even colonization of bacteria, if it enters the normally sterile parts of the body. Pathogenic bacteria is one that causes disease in the host. List of pathogenic bacteria is large enough, but there are some that are a common cause of disease in humans. Group of bacteria known as staphylococci, including Staphylococcus aureus, is one of the most common causes of human diseases. Most staphylococci colonize the skin and mucous membranes of people who have diseases. However, under certain conditions, staphylococci can cause superficial and systemic infection. Some of the most common superficial infections caused by S.aureus, including boils, impetigo and folliculitis. More serious and common infections caused by this organism strattera prescription is pneumonia, bacteremia and infections of bones and wounds. Staphylococcus aureus can produce toxins that can cause diseases such as various food poisoning and toxic shock syndrome. Other types of staphylococci, which usually cause disease in humans are Staphylococcus saprophyticus. This is the main cause of urinary tract infections in sexually active women. As staphylococcus, streptococcus are many kinds usually found in the human body. Some strains of streptococci causing some of the most serious diseases in humans. Streptococcus pyogenes (group A streptococcus) is the leading cause of bacterial pharyngitis (throat inflammation) in humans. Untreated strep throat can lead to serious consequences, as rheumatic fever (heart valves) and glomerulonephritis (kidney). Other infections include impetigo and destructive "flesh is bacteria", otherwise known as necrotizing fastsyyt. In necrotic fastsyyt, rapid destruction of soft tissues and muscles. This often fatal disease and prompt treatment. There are dozens of different species of gram-negative bacteria, with many species that are normally found in the gastrointestinal tract. In the gastrointestinal tract, they will favorably affect the body, preventing excessive growth of potentially pathogenic microorganisms. However, if surgery or trauma, these bacteria enter the gut, they can cause serious, life-threatening disease. One of the most common gram-negative bacteria that cause disease in humans is E. coli. According to Bailey and Scott's "Diagnostic Microbiology", E. coli, of course, is the most common cause of community acquired uncomplicated urinary tract infection and is often seen in wound infection. Some strains of E. coli (eg E. coli O157: H7) can cause severe diarrhea and kidney. Salmonella and shigella two gram-negative bacillus is well known as causes of food poisoning and dysentery, respectively. Gram-negative rods have been implicated in infections as diverse as pneumonia to ear infections. Most species of Neisseria are usually in the mouth and female genitalia. However, there are two types that can cause serious disease in humans. Gonococci cause infections, sexually transmitted gonorrhea. This is a major public health problems in the United States and worldwide. Untreated gonorrhea infections can lead to more serious diseases like arthritis and honokokkovoy pelvic inflammatory disease (PID). Neisseria meningitis is a causative agent of meningococcal meningitis, a serious, potentially life-threatening disease cerebrospinal fluid and meninges.
