Cat Scratch Disease and Bartonellaceae: The Known, the Unknown and the Curious.

Pediatr Infect Dis J 2021 May;40(5S):S11-S15

From the Division of Pediatric Infectious Diseases, Harbor-UCLA Medical Center, Los Angeles, California.

Since the early 1900s, Bartonella species were known only to cause human disease resulting from very restricted geographic (bartonellosis) or environmental influences ("trench fever"). In the 1990s, and in parallel, cat scratch disease and bacillary angiomatosis were definitively linked to Bartonella species. Subsequently, widespread use of modern diagnostic methods revealed the broad ecologic niche of this organism and greatly expanded our knowledge of the epidemiology and clinical presentations associated with this genus.

Detection of Bartonella sp. in ticks and their small mammal hosts in mangrove forests of Peninsular Malaysia.

Trop Biomed 2020 Dec;37(4):919-931

Department of Biological Sciences and Biotechnology, Faculty of Science and Technology, Universiti Kebangsaan Malaysia, 43600 UKM Bangi, Selangor, Malaysia.

Bacteria of the genus Bartonella have been known as emerging zoonotic pathogens for several human diseases including cat scratch disease, Carrion's disease and trench fever. Numerous species of small mammals have been reported to play a role as a suitable reservoir to many pathogenic Bartonella. These infections are thought to be transmitted through blood-feeding arthropod vectors such as ticks, fleas and lice. Read More

Cutis 2020 Nov;106(5):233-235

Department of Dermatology and Dermatologic Surgery, Medical University of South Carolina, Charleston, USA.

The human flea, Pulex irritans, is an important vector in the transmission of human diseases. This flea has been identified as a vector for the bubonic plague as far back as the 14th century, causing millions of deaths. Pulex irritans also has been identified as a vector for Bartonella bacteria species, which can cause trench fever. Read More

A Case of Bartonella Quintana Culture-Negative Endocarditis.

Am J Case Rep 2019 Apr 26;20:602-606. Epub 2019 Apr 26.

Institute of Human Virology, Department of Medicine, University of Maryland School of Medicine, Baltimore, MD, USA.

BACKGROUND Culture-negative Bartonella quintana endocarditis is challenging to diagnose and is associated with high mortality rates. Diagnostic confirmation of Bartonella quintana infection requires specialized assays, as identifying Bartonella henselae endocarditis by serology can be difficult due to the high rate of serological cross-reactivity. This is a case report of culture-negative Bartonella quintana endocarditis that was diagnosed with epidemiologic data, histology, and nucleic acid amplification testing. Read More

Evaluation of cell culture-grown Bartonella antigens in immunofluorescent antibody assays for the serological diagnosis of bartonellosis in dogs.

J Vet Intern Med 2018 Nov 11;32(6):1958-1964. Epub 2018 Oct 11.

Department of Clinical Sciences and the Intracellular Pathogens Research Laboratory, Center for Comparative Medicine and Translational Research, College of Veterinary Medicine, North Carolina State University, Raleigh, North Carolina.

Background: Because of poor sensitivity and questionable specificity of immunofluorescent antibody assays (IFAs), serological diagnosis of Bartonella species infections in dogs remains challenging. Despite limitations, IFA testing is the historical "gold standard" for Bartonella serodiagnosis in animals and humans. Because most diagnostic laboratories test against only 1 or 2 Bartonella spp. Read More

Detection of bacterial pathogens including potential new species in human head lice from Mali.

PLoS One 2017 20;12(9):e0184621. Epub 2017 Sep 20.

Aix Marseille Univ, CNRS, IRD, INSERM, AP-HM, URMITE, IHU - Méditerranée Infection, Marseille, France.

In poor African countries, where no medical and biological facilities are available, the identification of potential emerging pathogens of concern at an early stage is challenging. Head lice, Pediculus humanus capitis, have a short life, feed only on human blood and do not transmit pathogens to their progeny. They are, therefore, a perfect tool for the xenodiagnosis of current or recent human infection. Read More
