The data of numerous studies carried out in Spain are conclusive: the children of families who have a pet present a more stable immune system than those that do not live with pets. Without a doubt, home animals can give us a lot of Healthy benefits, both physical and emotional.
However, in specific cases in which the animal is a bearer of a bacterium (something that should not happen if we have them up to date in veterinary vaccines and reviews), could spread. It is true that The young usually have a greater repertoire of ‘Bartonella’ ... In the disease called the cat scratch, it can happen that street felines scratch, call or bite, or enter in some way with their infected saliva, so that the disease would overeverate.
These are the symptoms of cat scratch disease

Once we know that the disease is transmitted by the scratch of a cat, or through its saliva, the most common symptoms go through the formation of A blister, which is usually the first alarm sample. The contagion of this infection that is not usually serious produces a sensation of inexplicable tiredness, headache, inflammation of lymph nodes and, in some cases, some fever.
Much less common are symptoms such as weight loss that does not respond to any concrete cause, lack of appetite and even throat. Experts warn that this infection is not only transmitted through a specific action of the cat that carries it, but also We can spread if the animal has fleasthat house different species of this bacterium; That is, fleas act as vectors.
Another curiosity has to do with what The most affected children are For this transmission. As the MSD manual experts explain, in the 3 to 10 days after suffering the bite or the scratch, most patients with cat scratch disease develop a Erythematous indolor papule with crust (rarely a pustule) at the site of the lesion.
Diagnosis and treatment of cat scratch infection

The way in which doctors will confirm the diagnosis of the disease will be through titles of positive serum antibodies (It is recommended to analyze the serum in the acute phase and in the conventions, with 6 weeks of difference) or through PCR tests, in sucking samples of the lymph nodes.
Another step for confirmation is a biopsy of lymph nodes. The problem arises when suspicions occur in patients with Immunocompromiso, which will need the reinforcement of antibiotics. In all others, those who have strengthened defenses, the treatment is based on administering local heat and analgesics.
