Surveillance for zoonotic vector-borne infections using sick dogs from southeastern Brazil
(Mary Ann Liebert, Inc., 2007-12-01)
For many vector-borne organisms, dogs can be used as sentinels to estimate the risk of human infection. The objective of this study was to use dogs as sentinels for multiple vector-borne organisms in order to evaluate the ...
Estimation of R(0) from the initial phase of an outbreak of a vector-borne infection
(WILEY-BLACKWELL PUBLISHING, INC, 2010)
The magnitude of the basic reproduction ratio R(0) of an epidemic can be estimated in several ways, namely, from the final size of the epidemic, from the average age at first infection, or from the initial growth phase of ...
A hypothesis for explaining single outbreaks (like the Black Death in European cities) of vector-borne infections
(CHURCHILL LIVINGSTONE, 2009)
We propose a mechanism by which single outbreaks of vector-borne infections can happen even when the value of the basic reproduction number, R(o), of the infection is below one. With this hypothesis we have shown that ...
Vectorial capacity, basic reproduction number, force of infection and all that: formal notation to complete and adjust their classical concepts and equations
(FUNDACO OSWALDO CRUZRIO DE JANEIRO, RJ, 2012)
A dimensional analysis of the classical equations related to the dynamics of vector-borne infections is presented. It is provided a formal notation to complete the expressions for the Ross' threshold theorem, the Macdonald's ...
Modeling Vaccine Preventable Vector-borne Infectations: Yellow Fever As A Case Study
(World Scientific Publ CO PTE LTDSingapore, 2016)
Ehrlichia sp infection in carthorses of low-income owners, Southern Brazil
(Elsevier B.V., 2016-10-01)
Although well established in dogs, Ehrlichia sp. infection has been scarcely reported in horses. The aim was to perform a comprehensive serological and molecular survey for the detection of Ehrlichia spp. in carthorses ...
Babesia conradae infection in coyote hunting dogs infected with multiple blood-borne pathogens
(Wiley-Blackwell, 2018-09-01)
BackgroundObjectivesBabesia conradae is an intraerythrocytic piroplasm infecting dogs in the southern United States. Ticks have been suspected, but unproven, as vectors. We identified B. conradae and other blood-borne ...
Vector within-host feeding preference mediates transmission of a heterogeneously distributed pathogen
(WILEY-BLACKWELL, 2010)
2. We documented the within-host distribution of two vector species that differ in transmission efficiency, the leafhoppers Draeculacephala minerva and Graphocephala atropunctata, and which are free to move throughout ...
Mathematical modelling of vector-borne diseases and insecticide resistance evolution
(2017-07-06)
Background: Vector-borne diseases are important public health issues and, consequently, in silico models that simulate them can be useful. The susceptible-infected-recovered (SIR) model simulates the population dynamics ...
