Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry as a useful tool for the rapid identification of wild flea vectors preserved in alcohol.

Med Vet Entomol 2018 Dec 5. Epub 2018 Dec 5.

Institut de Recherche pour le Développement (IRD), Assistance Publique-Hôpitaux de Marseille (AP-HM), Service de Santé des Armées (SSA), Vecteurs-Infections Tropicales et Méditerranéennes (VITROME), Institut Hospitalo-Universitaire (IHU) Méditerranée Infection, Aix Marseille University, Marseille, France.

Flea identification is a significant issue because some species are considered as important vectors of several human pathogens that have emerged or re-emerged recently, such as Bartonella henselae (Rhizobiales: Bartonellaceae) and Rickettsia felis (Rickettsiales: Rickettsiaceae). Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has been evaluated in recent years for the identification of multicellular organisms, including arthropods. A preliminary study corroborated the usefulness of this technique for the rapid identification of fleas, creating a preliminary database containing the spectra of five species of flea. 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

Molecular detection and clinical characteristics of Bartonella bacilliformis, Leptospira spp., and Rickettsia spp. in the Southeastern Peruvian Amazon basin.

BMC Infect Dis 2018 Dec 4;18(1):618. Epub 2018 Dec 4.

School of Medicine. Faculty of Health Sciences. Research and Innovation Centre of the Faculty of Health Sciences, Universidad Peruana de Ciencias Aplicadas, Lima, Peru.

Background: Acute febrile illness (AFI) represent a significant health challenge in the Peruvian Amazon basin population due to their diverse etiologies and the unavailability of specific on-site diagnostic methods, resulting in underreporting of cases. In Peru, one of the most endemic regions to dengue and leptospirosis is Madre de Dios, a region also endemic to emergent bacterial etiologic agents of AFI, such as bartonellosis and rickettsiosis, whose prevalence is usually underreported. We aimed to molecularly identify the presence of Leptospira spp. Read More

Human Exposure to Novel Bartonella Species from Contact with Fruit Bats.

Emerg Infect Dis 2018 Dec;24(12):2317-2323

Twice a year in southwestern Nigeria, during a traditional bat festival, community participants enter designated caves to capture bats, which are then consumed for food or traded. We investigated the presence of Bartonella species in Egyptian fruit bats (Rousettus aegyptiacus) and bat flies (Eucampsipoda africana) from these caves and assessed whether Bartonella infections had occurred in persons from the surrounding communities. Our results indicate that these bats and flies harbor Bartonella strains, which multilocus sequence typing indicated probably represent a novel Bartonella species, proposed as Bartonella rousetti.

Untangling the knots: Co-infection and diversity of Bartonella from wild gerbils and their associated fleas.

Mol Ecol 2018 Oct 24. Epub 2018 Oct 24.

Koret School of Veterinary Medicine, The Hebrew University of Jerusalem, Rehovot, Israel.

Based on molecular data, previous studies have suggested a high overall diversity and co-infection rates of Bartonella bacteria in wild rodents and their fleas. However, partial genetic characterization of uncultured co-infecting bacteria limited sound conclusions concerning intra- and inter-specific diversity of the circulating Bartonella. To overcome this limitation, Bartonella infections of wild populations of two sympatric gerbil species and their fleas were explored by multiple isolations of Bartonella organisms. Read More

Zoonotic pathogens in fluctuating common vole (Microtus arvalis) populations: occurrence and dynamics.

Parasitology 2018 Sep 24:1-10. Epub 2018 Sep 24.

Instituto de Investigación en Recursos Cinegéticos,IREC (CSIC-UCLM-JCCM), Ronda de Toledo s/n, 13071, Ciudad Real,Spain.

Diseases and host dynamics are linked, but their associations may vary in strength, be time-lagged, and depend on environmental influences. Where a vector is involved in disease transmission, its dynamics are an additional influence, and we often lack a general understanding on how diseases, hosts and vectors interact. We report on the occurrence of six zoonotic arthropod-borne pathogens (Anaplasma, Bartonella, Borrelia, Coxiella, Francisella and Rickettsia) in common voles (Microtus arvalis) throughout a population fluctuation and how their prevalence varies according to host density, seasonality and vector prevalence.
