Cat-scratch disease (CSD) is a zoonosis in children, result of infection by Bartonella henselae, a gram-negative bacillus. Infection is generally characterized by regional and self-limited lymphadenopathy after exposure to a scratch or bite from a cat. Rarely, B. henselae is cause of fever of unknown origin (FUO), with dissemination to various organs, most often involving the reticuloendothelial system (liver, spleen, bone marrow), mimicking an inflammatory rather than a lymphoproliferative disease. Whole-body Magnetic Resonance Imaging (WBMRI), in association with diffusion-weighted imaging (DWIBS), allows a comprehensive evaluation of pediatric patients, without the risks inherent to ionizing radiation...

Bartonellosis is caused by the genus Bartonella. Bartonella is widely distributed in the ruminants, cats, dogs, rodents and other mammals including humans. At least 13 species or subspecies of Bartonella are zoonotic, and each species appears to be highly adapted to one or a limited number of reservoir animals in which it is asymptomatic, while it can be transmitted to humans in which a variety of clinical manifestations can be caused. It was reported that Bartonella henselae infection rate among domestic cats was high in nature, making it one of the leading, important, and easily neglected zoonotic diseases...

Infections in immunocompromised patients after hematopoietic stem cell transplantation can have a severe and atypical course. Some opportunistic pathogens are difficult to detect in microbiological tests, and that is why treatment success depends on an accurate clinical diagnosis. This article presents a case of a 7-year-old girl with severe aplastic anemia treated with bone marrow transplantation with post-transplantation period complicated by persistent, hectic fever, with peak episodes of 39-40°C, lasting several weeks...

Severe anemia and cholestatic hepatitis are associated with bartonella infections. A putative vertical Bartonella henselae infection was defined on the basis of ultrastructural and molecular analyses in a three-year-old child with anemia, jaundice and hepatosplenomegaly since birth. Physicians should consider bartonellosis in patients with anemia and hepatitis of unknown origin.

Cat scratch disease (CSD) - bartonellosis, is zoonosis caused by the intracellular gram negativebacterium Bartonellahenselae or Bartonellaquintana. The pathogens of this disease enter the human body usually as a consequence of a bite or scratch by young cats which are the natural source of such bacteria. The illness proceeds asymptomatically or with topical symptoms of infection such as a lump, spot or blister. Within 14 days a high fever and topical lymphadenopathy are observed. Lymph nodes are sore and start suppurating...

BACKGROUND: Cat-scratch disease (CSD) is a common infection in children; however, the wide spectrum of its clinical picture may lead to delayed diagnosis. An unusual presentation of CSD includes in the differential diagnosis malignant diseases, Epstein-Barr and cytomegalovirus infections, tuberculosis, and mycobacterioses. The diagnostic procedure is difficult, and it is important to consider CSD as the etiology of untypical lesion. PATIENTS AND METHOD: We present the analysis of 22 immunocompetent children treated with the clinical diagnosis of CSD in our hospital...

Several rodent-associated Bartonella species cause disease in humans but little is known about their epidemiology in Brazil. The presence of Bartonella spp. in wild rodents captured in two municipalities of the Mato Grosso do Sul state was assessed by polymerase chain reaction (PCR). Fragments of heart tissue from 42 wild rodents were tested using primers targeting the Bartonella 16S-23S intergenic transcribed spacer (ITS) region and citrate synthase gltA gene. The wild rodents were identified based on external and cranial morphology and confirmed at species level by mitochondrial DNA (cytochrome B) sequencing and karyotype...

BACKGROUND: Bartonellosis is an emerging zoonotic infection responsible for a variety of clinical syndromes in humans and animals. Members of the genus Bartonella exhibit high degrees of genetic diversity and ecologic plasticity. The infection is usually transmitted to animals and humans through blood-feeding arthropod vectors such as fleas, lice, ticks and sandflies. This study was conducted to investigate the prevalence of Bartonella species in 184 beef cattle, 40 dairy cattle, 40 sheep and 40 goats in eight animal farms across Peninsular Malaysia...

Cat scratch disease is caused by Bartonella henselae and usually manifests as localized lymphadenopathy and fever in immunocompetent patients. Immunocompromised patients are at risk for developing disseminated disease affecting the liver, spleen, eyes, central nervous system, and other organs. Bartonellosis is infrequently reported in solid organ transplant recipients, and published case reports usually discuss disseminated infection. Localized ocular disease with B. henselae, while well documented in immunocompetent hosts, is uncommon in immunocompromised patients...

Bartonella henselae, a flea-transmitted bacterium, causes chronic, zoonotic, blood stream infections in immunocompetent and immunocompromised patients throughout the world. As an intra-erythrocytic and endotheliotropic bacterium, B. henselae causes a spectrum of symptomatology ranging from asymptomatic bacteremia to fever, endocarditis and death. Veterinary workers are at occupational risk for acquiring bartonellosis. As an emerging, and incompletely understood, stealth bacterial pathogen, B. henselae may or may not have been responsible for the deaths of two veterinarians; however, recent evidence indicates that this genus is of much greater medical importance than is currently appreciated by the majority of the biomedical community...

We report a case of Bartonella henselae, an agent of cat scratch disease, C1-C2 osteoarthritis with osteolysis of the lateral mass of C2 in a 14-year-old boy. Oral antibiotics did not successfully treat the infection and surgery was necessary to treat the septic arthritis. The case opens discussion about bacterial osteoarthritis of the cervical spine and bone involvement in disseminated bartonellosis.

This is the case of a middle-aged male with no other medical issues who presented with acute, unilateral visual disturbance. In lieu of specific ophthalmologic findings, his age and presentation, he was treated for presumed inflammatory process. It was only after steroids and the results of serological testing that an infectious agent was determined. He was eventually diagnosed with ocular Bartonellosis. He was treated with oral doxycycline and rifampin and slowly improved. The thesis of this case report is that a thorough history prior to rapid and somewhat presumptive treatment may have prevented unnecessary immunosuppression and delay in appropriate antimicrobial therapy...
