Multidimensional perspectives of geo-epidemiology: from interdisciplinary learning and research to cost–benefit oriented decision-making Open
Research typically promotes two types of outcomes (inventions and discoveries), which induce a virtuous cycle: something suspected or desired (not previously demonstrated) may become known or feasible once a new tool or procedure is invent…
<i>Brucella microti</i> and Rodent‐Borne Brucellosis: A Neglected Public Health Threat Open
Brucellosis is one of the most important zoonoses worldwide, primarily affecting livestock but also posing a serious threat to public health. The major Brucella species are known to cause a feverish disease in humans with various clinical …

Ectoparasite and bacterial population genetics and community structure indicate extent of bat movement across an island chain Open
Few studies have examined the genetic population structure of vector-borne microparasites in wildlife, making it unclear how much these systems can reveal about the movement of their associated hosts. This study examined the complex host–v…

Geo-temporal patterns to design cost-effective interventions for zoonotic diseases -the case of brucellosis in the country of Georgia Open
Introduction Control of zoonosis can benefit from geo-referenced procedures. Focusing on brucellosis, here the ability of two methods to distinguish disease dissemination patterns and promote cost-effective interventions was compared. Meth…
Assessing complexity and dynamics in epidemics: geographical barriers and facilitators of foot-and-mouth disease dissemination Open
Introduction Physical and non-physical processes that occur in nature may influence biological processes, such as dissemination of infectious diseases. However, such processes may be hard to detect when they are complex systems. Because co…
Bartonella in Norway rats (Rattus norvegicus) from the urban slum environment in Brazil Open
Bartonella are rodent-borne bacteria that cause varied human etiologies. Studies on synanthropic rodents are rare, causing gaps in epidemiological knowledge. We tested bloodclot samples from 79 rats from an urban slum in Salvador, Brazil t…
Plague and Trace Metals in Natural Systems Open
All pathogenic organisms are exposed to abiotic influences such as the microclimates and chemical constituents of their environments. Even those pathogens that exist primarily within their hosts or vectors can be influenced directly or ind…

Comparison of sand fly trapping approaches for vector surveillance of Leishmania and Bartonella species in ecologically distinct, endemic regions of Peru Open
Background In Peru, the information regarding sand fly vectors of leishmaniasis and bartonellosis in the Amazon region is limited. In this study, we carried out sand fly collections in Peruvian lowland and highland jungle areas using diffe…
Exposure of Domestic Cats to Three Zoonotic Bartonella Species in the United States Open
Cat-associated Bartonella species, which include B. henselae, B. koehlerae, and B. clarridgeiae, can cause mild to severe illness in humans. In the present study, we evaluated 1362 serum samples obtained from domestic cats across the U.S. …
Manipulating vector transmission reveals local processes in bacterial communities of bats Open
Infectious diseases result from multiple interactions among microbes and hosts, but community ecology approaches are rarely applied. Manipulation of vector populations provides a unique opportunity to test the importance of vectors in infe…
Trypanosoma (Herpetosoma) diversity in rodents and lagomorphs of New Mexico with a focus on epizootological aspects of infection in Southern Plains woodrats (Neotoma micropus) Open
Protozoan parasites of the genus Trypanosoma infect a broad diversity of vertebrates and several species cause significant illness in humans. However, understanding of the phylogenetic diversity, host associations, and infection dynamics o…
Flea Presence and Abundance Are not Predictors of <i>Bartonella tribocorum</i> Carriage in Norway Rats ( <i>Rattus norvegicus</i> ) from an Underserved Neighborhood of Vancouver, Canada Open
Urban Norway rats (Rattus norvegicus) carry pathogenic Bartonella spp. that are transmitted among rats and from rats to people through arthropod vectors, particularly fleas. There is marked temporospatial variation in Bartonella spp. carri…
Molecular detection of<i>Bartonella henselae, Bartonella clarridgeiae</i>and<i>Rickettsia felis</i>in cat and dog fleas in Tenerife, Canary Islands, Spain Open
The cat flea Ctenocephalides felis is the main vector of Bartonella henselae and Bartonella clarridgeiae, the causative agents of cat-scratch disease (CSD) and the spotted-fever agent Rickettsia felis. In spite of their worldwide distribut…
Pentaplex real‐time PCR for differential detection of <i>Yersinia pestis</i> and <i>Y</i>.<i> pseudotuberculosis</i> and application for testing fleas collected during plague epizootics Open
Upon acquiring two unique plasmids (pMT1 and pPCP1) and genome rearrangement during the evolution from Yersinia pseudotuberculosis , the plague causative agent Y . pestis is closely related to Y . pseudotuberculosis genetically but became …
Identification of a Novel Yersinia enterocolitica Strain from Bats in Association with a Bat Die-Off That Occurred in Georgia (Caucasus) Open
Yersinia entercolitica is a bacterial species within the genus Yersinia, mostly known as a human enteric pathogen, but also recognized as a zoonotic agent widespread in domestic pigs. Findings of this bacterium in wild animals are very lim…
Bats are key hosts in the radiation of mammal-associated <i>Bartonella</i> bacteria Open
Bats are notorious reservoirs of several zoonotic diseases and may be uniquely tolerant of infection among mammals. Broad sampling has revealed the importance of bats in the diversification and spread of viruses and eukaryotes to other ani…
