Gene duplication and deletion, not horizontal transfer, drove intra-species mosaicism of Bartonella henselae.

Genomics 2019 Mar 19. Epub 2019 Mar 19.

School of Biotechnology, Amrita Vishwa Vidyapeetham, Kollam 690 525, Kerala, India. Electronic address:

Bartonella henselae is a facultative intracellular pathogen that occurs worldwide and is responsible primarily for cat-scratch disease in young people and bacillary angiomatosis in immunocompromised patients. The principal source of genome-level diversity that contributes to B. henselae's host-adaptive features is thought to be horizontal gene transfer events. Read More

Bartonella infections in cats and dogs including zoonotic aspects.

Parasit Vectors 2018 Dec 4;11(1):624. Epub 2018 Dec 4.

Departament de Medicina i Cirurgia Animals, Facultat de Veterinària, Universitat Autònoma de Barcelona, 08193, Bellaterra, Spain.

Bartonellosis is a vector-borne zoonotic disease with worldwide distribution that can infect humans and a large number of mammals including small companion animals (cats and dogs). In recent years, an increasing number of studies from around the world have reported Bartonella infections, although publications have predominantly focused on the North American perspective. Currently, clinico-pathological data from Europe are more limited, suggesting that bartonellosis may be an infrequent or underdiagnosed infectious disease in cats and dogs. Read More

Cat-Scratch Disease in an AIDS Patient Presenting with Generalized Lymphadenopathy: An Unusual Presentation with Delayed Diagnosis.

Am J Case Rep 2018 Aug 2;19:906-911. Epub 2018 Aug 2.

Department of Internal Medicine, Icahn School of Medicine at Mount Sinai, New York, NY, USA.

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

Departamento de Biología Molecular and Instituto de Biomedicina y Biotecnología de Cantabria (IBBTEC), Universidad de Cantabria-CSIC-SODERCAN, Santander, Spain

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 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. Read More

Despite the publication of a number of case reports since the 1950s, physician awareness of the unique relationship between cat scratch disease (CSD) and acute encephalopathy remains limited. This report alerts emergency medicine physicians to include CSD encephalopathy (CSDE) in the differential diagnosis when a previously healthy child presents with status epilepticus. Prompt recognition of this relationship impacts the selection of initial diagnostic studies and antibiotic choices and permits reliable insight into prognosis. Read More

Am J Surg Pathol 2016 Mar;40(3):342-7

Mayo Clinic, Division of Hematopathology, Rochester, MN.

Bartonella henselae lymphadenitis, or cat-scratch lymphadenitis (CSL), is classically associated with stellate microabscesses, occasional giant cells, and extension of the inflammatory infiltrate into perinodal soft tissue. Availability of B. henselae molecular testing on tissue specimens has broadened our understanding of the morphologic variation in this disease. Read More

Bacillary Angiomatosis in Immunocompetent Patient with Atypical Manifestations.

Indian J Dermatol 2015 Sep-Oct;60(5):523

Department of Pathology, Isfahan University of Medical Sciences, Isfahan, Iran.

Bacillary angiomatosis is an infectious disease caused by two Gram-negative bacilli; this disease usually affects immunosuppressed hosts with a history of cat scratch. We report a rare case of bacillary angiomatosis in an immunocompetent 26-year-old woman with no history of exposure to cats, and with atypical clinical features (very pruritic vascular papules and nodules with ulceration and hemorrhage on the right arm and fingers). She was successfully treated with clarithromycin for 3 months. Read More

Indian J Sex Transm Dis AIDS 2015 Jan-Jun;36(1):92-4

Department of STD, SHIFA Hospitals, Tirunelveli, Tamil Nadu, India.

A 14 year old boy, said to have had multiple transfusions during infancy, was brought to the hospital for complaints of pain over right thigh for one week duration. MRI reveals multiple osteolytic lesions with enhancing hyperintense bone marrow lesions over iliac bones, right acetabulum and lumbar vertebral bodies and enlarged para-aortic, iliac and inguinal lymph nodes. CT of the whole body revealed osteolytic lesions on skull, mandible, right scapula, head of both humeri, L1 and L4 vertebrae, 5(th) and 10(th) ribs, both acetabulum and ala of sacrum along with enlargement of cervical, axillary and mesenteric, iliac and inguinal nodes.

[Dermatologic manifestations associated with HIV/AIDS].

Rev Chilena Infectol 2015 Feb;32 Suppl 1:S57-71

The ongoing human immunodeficiency virus (HIV) infection epidemic coupled with more efficacious and available treatments has led to a larger number of patients living with HIV or AIDS. As a result, skin manifestations related to HIV/AIDS or its therapy have become increasingly more common and are reported to occur in as many as 95% of patients. Herein, we review the most common HIV/AIDS related cutaneous pathologies and classify them into inflammatory, HAART-associated, neoplastic, and infectious manifestations. Read More

Reprogramming of myeloid angiogenic cells by Bartonella henselae leads to microenvironmental regulation of pathological angiogenesis.

Cell Microbiol 2015 Oct 19;17(10):1447-63. Epub 2015 May 19.

Institute for Medical Microbiology and Infection Control, Goethe University, Frankfurt am Main, Germany.

The contribution of myeloid cells to tumour microenvironments is a decisive factor in cancer progression. Tumour-associated macrophages (TAMs) mediate tumour invasion and angiogenesis through matrix remodelling, immune modulation and release of pro-angiogenic cytokines. Nothing is known about how pathogenic bacteria affect myeloid cells in these processes. Read More

Bartonella henselae infection-associated vasculitis and crescentic glomerulonephritis leading to renal allograft loss.

Transpl Infect Dis 2015 Jun 1;17(3):411-7. Epub 2015 Jun 1.

Department of Pathology, University of Maryland School of Medicine, Baltimore, Maryland, USA.

Bartonella henselae (BH) is the main cause of cat scratch disease (CSD), which more typically presents as a self-limited localized suppurative lymphadenopathy in immunocompetent individuals. In contrast, immunocompromised patients commonly have systemic disease with life-threatening complications. In addition to the angioproliferative lesions, such as bacillary angiomatosis, an increasing number of immune post-infectious complications are being recognized with BH infections, including glomerulonephritis, vasculitis, hemophagocytic syndrome, and neurological problems.

Infection with Bartonella henselae in a Danish family.

J Clin Microbiol 2015 May 4;53(5):1556-61. Epub 2015 Mar 4.

Intracellular Pathogens Research Laboratory, Center for Comparative Medicine and Translational Research, College of Veterinary Medicine, North Carolina State University, Raleigh, North Carolina, USA

Bartonella species constitute emerging, vector-borne, intravascular pathogens that produce long-lasting bacteremia in reservoir-adapted (natural host or passive carrier of a microorganism) and opportunistic hosts. With the advent of more sensitive and specific diagnostic tests, there is evolving microbiological evidence supporting concurrent infection with one or more Bartonella spp. in more than one family member; however, the mode(s) of transmission to or among family members remains unclear.
