Cat scratch disease (CSD) is caused by Bartonella henselae, which mainly affects children. The cat is the reservoir. The laboratory diagnosis is based on the detection of antibodies by the Indirect Immunofluorescence (IFI) assay. The objective of this study was to analyze the serological evidence of B. henselae infection in pediatric patients that met the clinical/epidemiological criteria for suspected CSD. We studied 92 patients, who were categorized into four serological groups: 1) IgG (+)/IgM(+), 31,5% (n=29); 2) IgG (-)/IgM(+), 10,9% (n=10); 3) IgG (+)/IgM(-), 9,8% (n=9); 4) IgG (-)/IgM(-), 47,8% (n=44)...

Bartonella henselae infection is a frequent zoonosis from the domestic cat. It is presented with regional lymphadenitis in the majority of cases. Searching and characterization of lymph nodes by diagnostic imaging can be useful in the differential diagnosis approach, with a clear advantage, because it is a noninvasive method. Currently, new diagnostic imaging techniques improves the quality of screening and characterization of adenopathies, such is the case of PET/CT, which allows a better evaluation of hypermetabolic lymph nodes, without considering the individual growth of each lymph node...

Bartonella henselae infection is a prevalent illness in Chile. It presents generally as a cat scratch disease or as a prolonged fever syndrome. There are atypical manifestations, which include central nervous system, bone, cardiac and hepato-esplenic compromised. We present an adolescent case with a history of fever, vomiting and ataxia, whose diagnosis was a central nervous system infection by Bartonella henselae associated with a choroid plexus papilloma. This case corresponds to an unusual presentation, with a challenging diagnosis...

Cat-scratch disease-associated vertebral osteomyelitis and epidural involvement are rare and may manifest with nonspecific chronic symptoms in children, such as fever or torticollis. We present only the fourth case in the literature describing epidural involvement in an immunocompetent boy presenting with fever, torticollis, and indiscriminate left upper back tenderness. Bartonella henselae serologies are important to consider because such atypical complications often are responsive to conservative management with antibiotics...

We evaluated the utility of Western blot (WB) bands of Bartonella henselae in detecting anti-B. henselae immunoglobulin M (IgM) for serodiagnosis of cat scratch disease (CSD). IgM band patterns were examined using sera from 92 patients clinically suspected of having CSD and from 130 healthy individuals. Positive WB bands were observed in 49 (53.5%) of the 92 patient sera. Three bands at 8 to 10, 31 to 35, and 70 kDa were regarded as relevant for B. henselae because all of the positive sera yielded at least one of the three bands, and none of the healthy control sera showed reactivity to any of them...

The cat flea Ctenocephalides felis felis (Bouché) is the most important ectoparasite of domestic cats and dogs worldwide. It has been two decades since the last comprehensive review concerning the biology and ecology of C. f. felis and its management. Since then there have been major advances in our understanding of the diseases associated with C. f. felis and their implications for humans and their pets. Two rickettsial diseases, flea-borne spotted fever and murine typhus, have been identified in domestic animal populations and cat fleas...

PURPOSE: Bartonella is an increasingly isolated emerging pathogen that can cause severe illness in humans, including cat scratch disease (CSD). The bacteria are difficult to grow and thus many detection methods have been developed, especially molecular. We previously developed a PCR method targeting ribC to identify Bartonella sp. A manufactured kit (RealCycler BART, Progenie Molecular) was commercialised shortly thereafter for the detection of Bartonella infection, including Bartonella henselae...

In brain cortex-ablated cats (BCAC), hind limb motoneurons activity patterns were studied during fictive locomotion (FL) or fictive scratching (FS) induced by pinna stimulation. In order to study motoneurons excitability: heteronymous monosynaptic reflex (HeMR), intracellular recording, and individual Ia afferent fiber antidromic activity (AA) were analyzed. The intraspinal cord microinjections of serotonin or glutamic acid effects were made to study their influence in FL or FS During FS, HeMR amplitude in extensor and bifunctional motoneurons increased prior to or during the respective electroneurogram (ENG)...

BACKGROUND: Cat scratch disease is a common infectious disorder caused by Bartonella henselae that is transmitted primarily by kittens. It typically exhibits a benign and self-limiting course of subacute regional lymphadenopathy and fever lasting two to eight weeks. The most severe complication of cat scratch disease is involvement of the nervous system, such as encephalitis, meningitis, and polyneuritis. Peripheral facial nerve palsy associated with Bartonella infection is rare; few reported pediatric and adult cases exist and the precise pathogenesis is unknown...

Bartonella henselae the causative agent of cat scratch disease (CSD), is a gram-negative, coccobacillus, facultative intracellular bacterium CSD usually presents as a clinical form of benign local lymphadenopathy (LAP) but sometimes it may progress to severe life threatening complications. Despite the fact that CSD is known to be a common disease, which is one of the important causes of local LAPs in the world, there are few publications in our country. For the diagnosis, the clinician should suspect for CSD and has to ask to the patient whether there is a story of cat scratch or not...

Vector-borne diseases (VBDs) are caused by a wide range of pathogens, which are transmitted by a variety of vectors, such as ticks and fleas. As a result of climate changes, more vector-borne diseases are becoming endemic in Germany, not only in dogs, but also in cats. For some of the pathogens prevalence data still need to be investigated in Germany. However, natural infections with Bartonella, Anaplasma, haemotropic Mycoplasma and Borrelia species have already been described in German cats. Clinical relevance of these pathogens is not fully understood, and it is still unknown, why most infected cats stay asymptomatic and which predisposing factors contribute to the development of clinical signs in cats...

REVIEW
Fateme Shamekhi Amiri
Systemic cat scratch disease or bartonellosis is a clinical entity caused by Bartonella henselae, which manifests with necrotizing granulomas in visceral organs. The cat flea, Ctenocephalides felis, is the vector responsible for horizontal transmission of the disease from cat to cat, and its bite can also infect humans. In immunocompromised patients including chronic kidney disease and renal transplant recipients, it can cause persistent and disseminated cat scratch disease. The aim of this paper is to perform a systematic review of the studies that have addressed the diagnostic methods of cat scratch disease in chronic kidney disease and renal transplant recipients...
