Prevalence, infected density or individual probability of infection? Assessing vector infection risk in the wild transmission of Chagas disease
(The Royal Society, 2020)
Vector-borne infectious disease dynamics result mainly from the intertwined effect of the diversity, abundance, and behaviour of hosts and vectors. Most studies, however, have analysed the relationship between host-species ...
Prevalence, infected density or individual probability of infection? Assessing vector infection risk in the wild transmission of Chagas disease
(2020-03-11)
Vector-borne infectious disease dynamics result mainly from the intertwined effect of the diversity, abundance, and behaviour of hosts and vectors. Most studies, however, have analysed the relationship between host-species ...
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 ...
Vector competence of Culex quinquefasciatus Say, 1823 exposed to different densities of microfilariae of Dirofilaria immitis (Leidy,1856)
(Soc Brasileira EntomologiaCuritibaBrasil, 2008)
High levels of human infection with Trypanosoma cruzi associated with the domestic density of infected vectors and hosts in a rural area of northeastern Argentina
(BioMed Central, 2018-08)
Background: Insecticide spraying campaigns designed to suppress the principal vectors of the Chagas disease usually lack an active surveillance system that copes with house reinvasion. Following an insecticide campaign ...
Somatic Wolbachia (Rickettsiales: Rickettsiaceae) Levels in Culex quinquefasciatus and Culex pipiens (Diptera: Culicidae) and Resistance to West Nile Virus Infection
(Entomological Society Of America, 2014-01)
The endosymbiotic bacteria Wolbachia pipientis Hertig infects a wide variety of insect species and can increase viral resistance in its host. Wolbachia naturally infects Culex quinquefasciatus Say and Culex pipiens L. ...
Relative contribution of low-density and asymptomatic infections to Plasmodium vivax transmission in the Amazon: pooled analysis of individual participant data from population-based cross-sectional surveys
(Elsevier, 2022)
Background: Low-density and asymptomatic Plasmodium vivax infections remain largely undetected and untreated and may contribute significantly to malaria transmission in the Amazon. Methods: We analysed individual participant ...
Effects of mammal host diversity and density on the infection level of Trypanosoma cruzi in sylvatic kissing bugs
(Blackwell Publishing Ltd, 2014)
© 2014 The Royal Entomological Society. Several reports have described host species diversity and identity as the most important factors influencing disease risk, producing either dilution or amplification of the pathogen ...
Landscape determinants of Saint Louis encephalitis human infections in Córdoba city, Argentina during 2010
(Elsevier Science, 2013-03-17)
Saint Louis encephalitis virus (SLEV) is endemic in Argentina. During 2005 an outbreak occurred in Córdoba. From January to April of 2010 a new outbreak occurred in Córdoba city with a lower magnitude than the one ...
