What are the symptoms of salmonellosis
Salmonella can cause many forms of infections, from strongly expressed to asymptomatic. The incubation period for salmonellosis usually lasts from 6 to 72 hours, but there is evidence that in some cases it can last more than ten days. The most common symptoms of salmonellosis are diarrhea, intestinal infection, nausea, vomiting, and abdominal cramps, fever (usually 38 to 39 degrees Celsius). Some patients have had symptoms such as blood in the stool, headache and muscle pain.
Usually the symptoms of salmonellosis are just 3-7 days. However, the bacteria remain for a while in the gut, and complete recovery of Salmonella in adult takes about a month, and for children - even longer.
How dangerous salmonella?
Approximately 5% of the gastrointestinal forms of salmonellosis lead to the development of bacteremia - a condition in which bacteria are present in the blood. A small percentage of these patients develop severe complications such salmonellosis as abscesses (including abscess

brain), and endocarditis. Overall, approximately 20% of patients who have diagnosed salmonella, require hospitalization, 5% of them develop any complications, and 0.5% among these patients, complications lead to death. Severe consequences of salmonellosis is especially common in children under one year, people over 65 years old and in immunocompromised patients caused by how different diseases and medications. Infections caused by antibiotic-resistant strains of Salmonella, are also associated with increased risk of serious complications.
It is estimated that 2-15% of cases of salmonellosis in humans leads to the development of complications such as reactive arthritis

. The symptoms of this disorder are pain and swelling in the joints, sometimes - an inflammation of the tendon. The most common reactive arthritis

It affects joints of the feet, much less - the joints of the hands, fingers, and lower back. In some patients, the disease also results in inflammation of the prostate, cervix or urethra, the eye, and even causes extensive skin rashes.
The symptoms of reactive arthritis occur, on average, 18 days after the first signs of salmonellosis. According to polls, to the doctor complaining of the above symptoms are treated, only about 15% of the total number of patients who develop this complication. In most cases, the disease takes several months later, but sometimes the symptoms of reactive arthritis may persist for several years. This disease is studied rather poorly and cure it is not currently possible; primary goal of treatment for reactive arthritis is to relieve his symptoms.
Finally, severe salmonellosis may lead to severe dehydration, which is extremely hazardous to health. Fortunately, timely hospitalization in most cases allows to avoid it.
Diagnosis of salmonellosis
In most cases, the diagnosis is prescribed a stool

to salmonellosis. When bacteremia and other complications of Salmonella could be detected in urine and, rarely, in different tissues of the body. Salmonella can also be detected by a blood test, but this method of diagnosis is used relatively infrequently.
Today, as a rule, doctors do a smear on salmonellosis from the anus. The resulting samples microflora on two or three days, are placed in culture medium, after which they were studying microbiologist. Such an analysis on salmonella can not only confirm the presence of an intestinal infection, but also to identify its originator.
If you are taking antibiotics, be sure to tell your doctor before carrying out tests - these drugs can lead to lozhnooritsatelnym results in infected patients.
