The cat scratch disease in humans is caused by the bacteria Bartonella henselae. The disease can take many different forms: from asymptomatic cases, cases of skin lesions, fever of unknown origin, enlargement of lymph nodes, ophthalmologic disorders, to severe cases involving inflammation of the brain and spinal cord or endocarditis. The reservoir of B. henselae for humans are domestic animals, especially cats. The diagnosis of the disease is based on data from the anamnesis, the patient’s confirmed exposure to cats, and the results of serological tests showing an increase in antibody titres for B. henselae. The disease can also be confirmed by positive results of the polymerase chain reaction (PCR). No vaccines against bartonellosis are available. The most important in preventing the disease is to maintain appropriate hygiene in contact with cats and dogs, and to eradicate the vectors of Bartonella, such as fleas.
