BACKGROUND: The genus Bartonella includes fastidious, facultative intracellular bacteria mainly transmitted by arthropods and distributed among mammalian reservoirs. Bartonella spp. implicated as etiological agents of zoonoses are increasing. Apart from the classical Bartonella henselae, B. bacilliformis or B. quintana, other species (B. elizabethae, B. rochalimae, B. vinsonii arupensis and B. v. berkhoffii, B. tamiae or B. koehlerae, among others) have also been associated with human and/or animal diseases...

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 patients' sera. Three bands at 8--10, 31--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...

Vector-borne infections are persistent public health threats worldwide. In recent years, a number of mosquito-borne viruses have emerged or re-emerged to cause major disease outbreaks. Other vector-borne pathogens, however, remain understudied and much neglected especially in the developing regions of the world including Southeast Asia. In this study, the brown dog tick Rhipicephalus sanguineus sensu lato, cat louse Felicola subrostratus, and cat fleas Ctenocephalides felis and Ctenocephalides orientis collected from free-ranging cats and dogs in Malaysia were molecularly screened for the presence of Bartonella and Rickettsia bacteria, and Dipylidium tapeworm...

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...

BACKGROUND: Bartonellosis is an emerging vector-borne disease caused by different intracellular bacteria of the genus Bartonella (Rhizobiales: Bartonellaceae) that is transmitted primarily by blood-sucking arthropods such as sandflies, ticks and fleas. In Tunisia, there are no data available identifying the vectors of Bartonella spp. In our research, we used molecular methods to detect and characterize Bartonella species circulating in fleas collected from domestic animals in several of the country's bioclimatic areas...

We compared a qualitative in-clinic (IC)-PCR for the detection of Mycoplasma haemofelis DNA with the results of a commercial qualitative laboratory-based, conventional (c)PCR. In order to determine the specificity of both tests, Bartonella spp. samples were included. Forty-three previously tested blood samples with known PCR results for hemoplasmas and Bartonella spp. were selected. The samples were split between 2 laboratories. At the first laboratory, DNA was purified and run on 2 cPCR assays for the detection of hemoplasmas and Bartonella spp...

Bacillary angiomatosis (BA) is an angioproliferative disease of immunocompromised patients that usually presents as vascular tumors in the skin and subcutaneous tissues. It is caused by chronic infections with either Bartonella henselae or B. quintana. Oral cavity BA is exceedingly rare and even rarer without simultaneous cutaneous disease. We report herein the case of a 51-year-old HIV-infected man who presented severe odynophagia and an eroded lesion on the hard palate that progressed to an oronasal fistula...

Cat-scratch disease is due to Bartonella henselae and commonly presents as a localised papular lesion with regional lymphadenopathy. We report the case of a young man suffering general symptoms and dysautonomy characterised by an erectile dysfunction due to an invasive cat-scratch disease. He was successfully treated by tetracyclines during 3 weeks.

Infectious diseases have been increasingly recognized in cats worldwide. The objective of this study was the molecular investigation of the prevalence of selected pathogens in healthy and sick cats from Greece, a country highly endemic for several canine vector-borne pathogens. Blood and/or bone marrow samples from 50 clinically healthy and 50 sick adult (>1 year-old) cats were retrospectively examined for the amplification of Bartonella spp., haemoplasmas, Ehrlichia spp., Anaplasma spp., Babesia spp., and Cytauxzoon spp...

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...

We explore the potential of bacterial secretion systems as tools for genomic modification of human cells. We previously showed that foreign DNA can be introduced into human cells through the Type IV A secretion system of the human pathogen Bartonella henselae. Moreover, the DNA is delivered covalently attached to the conjugative relaxase TrwC, which promotes its integration into the recipient genome. In this work, we report that this tool can be adapted to other target cells by using different relaxases and secretion systems...

Bartonella henselae is a relevant causative agent of bartonelloses in humans. We described an immunocompetent patient with clinical manifestation of chronic cervical lymphadenopathy after a cat-scratch in her forearm. This case shows B. henselae infection persistence even after prolonged antibiotic treatment.

Cat-scratch disease (CSD) is a common cause of chronic benign lymphadenopathy in the child and the young adult. Bartonella henselae is the agent responsible for this disease. Common symptoms include regional lymphadenopathy associated with fever. We report a clinically atypical and potentially misleading case of a 18-year old girl with CSD revealed by elbow abscess.

Cats are known to be the main reservoir for Bartonella henselae and Bartonella clarridgeiae, which are the agents of 'cat-scratch disease' in humans. In the present study, we investigated the prevalence of the two Bartonella species on 1754 cat bloods collected from all prefectures in Japan during 2007-2008 by a nested-polymerase chain reaction (PCR) targeting the 16S-23S rRNA internal transcribed spacer region. Overall, Bartonella DNA was detected in 4·6% (80/1754) of the cats examined. The nested-PCR showed that 48·8% (39/80) of the positive cats were infected with B...

Cat scratch disease (CSD) is a zoonotic infection caused primarily by the bacterium Bartonella henselae. An estimated 12,000 outpatients and 500 inpatients are diagnosed with CSD annually, yet little is known regarding clinician experience with and treatment of CSD in the United States. Questions assessing clinical burden, treatment and prevention of CSD were posed to 3,011 primary care providers (family practitioners, internists, paediatricians and nurse practitioners) during 2014-2015 as part of the annual nationwide DocStyles survey...
