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...

Outer membrane proteins (OMPs) of gram-negative bacteria constitute the first line of defense that protects the cells against environmental stresses including chemical, biophysical, and biological attacks. Although 43-kDa outer membrane protein (OMP43) is major porin protein among the Bartonella henselae-derived OMPs, its function remains unknown. In this study, OMP43-deficient mutant B. henselae (Δomp43) was generated to investigate function of OMP43. Interestingly, Δomp43 showed a weaker proliferative ability compared to wild type (WT) of B...

Cat scratch disease is a relatively rare infection that is caused by the bacterium Bartonella henselae. This disease occurs after cat scratch or bite. The course of the disease depends on the patients immunity status. In immunocompetent patients, the disease typically runs as a lymph node syndrome. Sometimes, mild general symptoms may appear, or the course can be atypical with a more serious clinical manifestation involving various organs. In immunocompromised patients, Bartonella henselae can cause bacillary angiomatosis or peliosis with a severe course...

Bartonella henselae, the agent of cat scratch disease (CSD), appears to be a common organism responsible for lymphadenitis in both adults and children. There is a very low isolation rate for B. henselae from lymph nodes of patients with CSD. Our objective was to evaluate B. henselae viability in a large series of lymph nodes from patients with CSD. From January to November 2016, we analyzed lymph node biopsy samples from patients diagnosed with CSD. We used reverse transcription-quantitative polymerase chain reaction (RT-qPCR) to detect B...

Recently, BAPGM enrichment culture has documented Bartonella bacteremia in previously healthy, "nonimmunocompromised" patients following arthropod exposures. Neurobartonellosis should be among the differential diagnoses for patients with persistent or recurrent neurological symptoms of undetermined etiology. Microbiological and immunological testing should be concurrently pursued to determine whether defective immune function accompanies Bartonella bacteremia.

Since the reclassification of the genus Bartonella in 1993, the number of species has grown from 1 to 45 currently designated members. Likewise, the association of different Bartonella species with human disease continues to grow, as does the range of clinical presentations associated with these bacteria. Among these, blood-culture-negative endocarditis stands out as a common, often undiagnosed, clinical presentation of infection with several different Bartonella species. The limitations of laboratory tests resulting in this underdiagnosis of Bartonella endocarditis are discussed...

Bacterial conjugation is a mechanism of horizontal DNA transfer. The relaxase TrwC of the conjugative plasmid R388 cleaves one strand of the transferred DNA at the oriT gene, covalently attaches to it, and leads the single-stranded DNA (ssDNA) into the recipient cell. In addition, TrwC catalyzes site-specific integration of the transferred DNA into its target sequence present in the genome of the recipient bacterium. Here, we report the analysis of the efficiency and specificity of the integrase activity of TrwC in human cells, using the type IV secretion system of the human pathogen Bartonella henselae to introduce relaxase-DNA complexes...

Two children with congenital heart disease status post surgical correction presented with prolonged constitutional symptoms, hepatosplenomegaly and pancytopenia. Concern for malignancy prompted bone marrow biopsies that were without evidence thereof. In case 1, echocardiography identified a multilobulated vegetation on the conduit valve. In case 2, transthoracic, transesophageal and intracardiac echocardiography were performed and were without evidence of cardiac vegetations; however, pulmonic emboli raised concern for infective endocarditis...

Acute worsening of visual acuity with optic disc edema is commonly assumed to be due to idiopathic intracranial hypertension. Bartonella henselae is an unusual cause to abrupt vision loss that is associated with optic disc edema and exudative macular stars seen on examination. It is an important cause to be aware of because it responds very well to antibiotic treatment. We present a case of a female adolescent with unilateral vision loss cause by cat-scratch neuroretinitis.

In this study, we examine the prevalence of three infectious pathogens with different transmission modes (Bartonella henselae, hemoplasma and Toxoplasma gondii) in feral cats (Felis catus) from two unique habitat types, urban and rural. We determined the infection status of three pathogens in blood samples (total N=117) through molecular or serological diagnostic methods. Overall prevalence of hemoplasma, T. gondii and B. henselae was 47.9%, 50% and 35.7%, respectively. Only seroprevalence of B. henselae was significantly higher in urban cats...

Bartonellae are blood-borne and vector-transmitted pathogens, some are zoonotic, which have been reported in several Mediterranean countries. Transmission from dogs to humans is suspected, but has not been clearly demonstrated. Our objectives were to determine the seroprevalence of Bartonella henselae, Bartonella vinsonii subsp. berkhoffii, Bartonella clarridgeiae, and Bartonella bovis (as a proxy for Candidatus Bartonella merieuxii) in stray dogs from Tunisia, identify the Bartonella species infecting the dogs and evaluate potential risk factors for canine infection...

Each year in the United States, 500 patients are hospitalized for cat-scratch disease, caused by Bartonella henselae infection. We report a case of rare but serious neurologic B. henselae infection. When typical features of cat-scratch disease occur with neurologic findings, Bartonella infection should be suspected and diagnostic testing should be performed.

BACKGROUND: Bartonella henselae is a highly prevalent, vector-borne pathogen. Transmission to humans and animals by ticks is discussed controversially. Here, we present a case report, where eleven Ixodes ricinus ticks all harbouring B. henselae DNA were removed from one single cat. RESULTS: The first feeding tick was tested positive for B. henselae DNA. The cat was also found to be seropositive for anti-B. henselae IgG antibodies (titer 1:640). Bartonella henselae was not cultivatable from cat blood...
