The article discusses the problem of the role of pets as a source of zoonotic infections, representing a hidden threat to modern society. Since the content is now very popular at home, both traditional and exotic animals, it is necessary to develop an interdisciplinary program to control the spread of zoonotic infections and the risks of their infection with people. Since the problem lies in the intersection of several disciplines, joint efforts of doctors, veterinarians, health organizers and laboratory specialists are necessary. Read More

Cat-scratch disease (CSD) is usually a self-limiting infection that in the majority of cases occurs as lymphadenitis in children who have been scratched or bitten by a cat. Rarely, Bartonella henselae is cause of fever of unknown origin (FUO), with dissemination to various organs, mimicking an inflammatory rather than a lymphoproliferative disease. This manuscript will present a case of thoracic manifestations of CSD in an immunocompetent 2-years baby without history of cat contact, with fever of unknown origin, investigated by chest CT and MRI.

BACKGROUND Bartonella infection is the causative organism of cat-scratch disease (CSD), which typically presents with self-limited localized lymphadenopathy. In HIV-infected patients, Bartonella infection can cause systemic illnesses with significant morbidity and mortality manifesting as bacillary angiomatosis (BA), hepatic peliosis, splenitis, bacteremic febrile illness, and other organ involvement. To the best of our knowledge, there have been no reports of HIV-infected patients presenting with generalized lymphadenopathy caused by Bartonella infection. Read More
