The cat scratch disease (CSD, for its acronym in English) is caused by a bacterial infection called Bartonella infection. It affects the lymph nodes draining the area where it occurs as a scratch or a cat bite, which causes a regional lymphadenopathy.<\/p>\n\n\n\n

The CSD is a common infection, and usually mild, which usually goes away by itself. However, some people with compromised immune systems may develop more serious infections, or have issues with the spread of the bacteria to other parts of the body.<\/p>\n\n\n\n

Symptoms<\/h2>\n\n\n\n

The cat scratch disease is caused by a bacterium called Bartonella henselae. It can be transmitted to humans by a scratch or bite from an infected cat. Kittens are more likely to carry the bacteria that senior cats.<\/p>\n\n\n\n

Usually is self-limited in healthy individuals, so that will go away by itself without treatment. But in some people, especially those who have HIV\/AIDS or other problems with your immune system, the CSD can worsen and cause more serious complications.<\/p>\n\n\n\n

A person who is sick with this infection can have many swollen lymph nodes in different places (lymph nodes are small glands filled with fluid in the body). The lymph nodes may become larger or more painful as the infection progresses. They can also change shape.<\/p>\n\n\n\n

Symptoms begin within 2 weeks of having been scratched or bitten by an infected cat. Include fever, headache, pain, nausea, vomiting, fatigue, loss of appetite, chills, or a general feeling of malaise.<\/p>\n\n\n\n

These symptoms usually disappear within 3 to 6 months. However, they can last a year or more.<\/p>\n\n\n\n

The swelling and pain may be relieved by taking anti-inflammatory medications-the-counter, such as ibuprofen (Advil, Motrin, Nuprin) or naproxen sodium (Aleve, Anaprox, Naprosyn). A hot compress can also help.<\/p>\n\n\n\n

You can also take antibiotics if you have problems with swelling and pain. These medicines can reduce the amount of swollen lymph nodes in your body and may also delay the spread of infection by Bartonella.<\/p>\n\n\n\n

Your doctor may do a blood test to see if you have the bacteria Bartonella in your body. There may also be a lymph node biopsy to see if the bacteria are in the lymph nodes.<\/p>\n\n\n\n

If the tests and the biopsy results show that you have the cat scratch disease, your doctor will talk with you about the symptoms you are experiencing. They will also talk about your health history, and other factors that may help make the diagnosis.<\/p>\n\n\n\n

Your doctor may use a special type of bacterial test call immunofluorescence assay to verify the presence of the bacteria Bartonella in your body. This test can detect the presence of bacteria in your body to observe a small portion of tissue that will grow under a microscope when the bacteria were exposed to the test.<\/p>\n\n\n

Diagnosis<\/h2>\n\n\n\n

The cat scratch disease is caused by bacterial infection Bartonella henselae. It is spread to people through bites or scratches from cats and can cause disease in immunocompromised patients.<\/p>\n\n\n\n

The symptoms usually occur a few days after the cat scratch. Begin with a small lump or blister that looks like an insect bite. The skin over the lump or blister becomes red and warm. The bulge or blister goes away in 3 weeks.<\/p>\n\n\n\n

Swollen lymph nodes (white spots enlarged) are another common symptom. These lymph nodes are usually found under the arm, or neck. The swelling can last from two to four months, but eventually will disappear.<\/p>\n\n\n\n

If a patient presents with lymphadenopathy, a biopsy can be taken of the affected area. This sample is then sent to a laboratory for analysis. A positive result of a laboratory test is sufficient to make the diagnosis of CSD.<\/p>\n\n\n\n

Laboratory testing for CSD include serological tests and PCR. These tests detect antibodies against Bartonella henselae in the blood. You can also use other tests to identify the type of Bartonella infection, which is important if there is more than one type of Bartonella involved.<\/p>\n\n\n\n

These tests usually performed by a veterinarian or a health care provider who has special training in the diagnosis and treatment of this infection. The tests can help your doctor make a diagnosis and provide information on the type of infection, cat-scratch disease your child has.<\/p>\n\n\n\n

Most healthy people do not get sick from this infection, but if your child develops symptoms, it is important to see a health professional. This will allow you to to your child's doctor to check if there are other conditions that may be causing the symptoms.<\/p>\n\n\n\n

Often, the infection will go away by itself, without any treatment. However, if the infection is severe or if your child has a disorder of the immune system, it is possible that your doctor will prescribe antibiotics to treat the infection.<\/p>\n\n\n\n

Bartonella henselae is a common cause of cat scratch disease, angiomatosis bacilar, endocarditis, and failure in immunocompromised patients. It can also cause a rare complication called osteomyelitis.<\/p>\n\n\n\n

Treatment<\/h2>\n\n\n\n

A person can become infected with cat scratch disease Bartonella Infection when you get a scratch or a bite from an infected cat. This is more common in children because they have a lot of contact with cats.<\/p>\n\n\n\n

The symptoms of cat scratch disease usually develop within 3 to 10 days after initial contact with an infected cat. The first sign of this infection is a bump or pustule develops in the place of the scratch. Then, within 1 to 7 weeks, the lymph nodes in the region of the scratch will swell.<\/p>\n\n\n\n

Inflammation of the lymph node is often painful and can measure up to 6 cm in diameter. This swelling is a sign of the Bartonella infection, the cat scratch disease, and should be examined by your doctor.<\/p>\n\n\n\n

This condition is caused by the bacterium rickettsial (similar to bacteria) Bartonella henselae and it can be spread to people who have contact with fleas infected. Infected fleas carried the bacterium Bartonella in their feces and in the products of the digestive produced when you digest your food.<\/p>\n\n\n\n

If the infection is caught early, the disease is a benign and self-limiting, that tends to get better by itself with time. Usually, you do not need to be treated with antibiotics, but may be useful if the infection is severe and affects the lungs or the liver.<\/p>\n\n\n\n

A patient can be diagnosed by a doctor who has the history and physical examination, correct, as well as through tests for the presence of the bacterium Bartonella in the blood. This is usually done with an ELISA assay or indirect fluorescence.<\/p>\n\n\n\n

The doctor might also take a sample of the lymph gland swollen and analyze it to detect Bartonella henselae. This can help to confirm the diagnosis and prevent other conditions that cause inflammation of the lymph nodes.<\/p>\n\n\n\n

The infection can cause more serious health problems, such as a bacterial infection that reaches the brain and cause encephalitis or meningitis in children. Other complications include follicular conjunctivitis, neurorretinitis and pos.<\/p>\n\n\n\n

Prevention<\/h2>\n\n\n\n

Bartonella is a group of bacteria that is transmitted to humans through insect carriers (vectors) as fleas, ticks, and lice. There are at least 22 species named Bartonella and several can cause disease in animals and humans. The species of Bartonella more associated with common human diseases are Bartonella henselae.<\/p>\n\n\n\n

The cat scratch disease occurs when a person is infected with Bartonella henselae after being bitten or scratched by a cat. The most common way for a cat to transmit Bartonella is through a wound-bite, but some cases of cat scratch disease can occur when people touch a cat, contaminated or her litter box.<\/p>\n\n\n\n

Patients generally develop a red nodule on the site of the scratch or bite and fever, headache, muscle pain, and fatigue within 3 to 10 days. Usually, it develops a lymphatic gland inflamed in the first 2 weeks and can ulcerate or drain fluid. The condition usually improves with time alone.<\/p>\n\n\n\n

The patient's treatment includes the application of local heat and antimicrobial to help reduce the infection in the lymph nodes affected. Needle aspiration of the lymph node is inflamed can relieve the pain.<\/p>\n\n\n\n

The prevention is based on avoiding scratches and bites from a cat, and the use of flea control. The most effective prevention is to avoid contact with cats and kittens, feral. If you have a cat, keep it inside and treat it regularly with medications for fleas.<\/p>\n\n\n\n

The infection in cats can also be spread to a person through a wound by the bite of a flea, although it is not known how often this occurs. Fleas eat blood that contains Bartonella in cats infected, replicated the bacteria in their bodies and eliminated in your stools.<\/p>\n\n\n\n

It is estimated that 5% of the population has been infected with Bartonella, and many of these infections are not diagnosed or not reported. The majority of infections are mild and go away in a few weeks without any treatment.<\/p>\n\n\n\n

However, the bacterial load in the system of a person and the virulence of the organism will determine if the infection is serious or not. People infected with a weakened immune system have a higher risk of complications. This explains why the CSD is most often seen in children and in immunocompromised individuals.<\/p>","protected":false},"excerpt":{"rendered":"
