1. Factors associated with the presence of triatomines in rural areas of south Argentine Chaco
Abstract INTRODUCTION: The domestic and peridomestic presence of Triatoma infestans depends on several factors, such as human behavior, vector behavior, ecology, and the environment. METHODS: This work was conducted in 139 domiciliary units, where triatomines were captured and risk factors in domiciles and peridomicilies were recorded. Household dwellers

2. The eco-epidemiology of Triatoma infestans in the temperate Monte Desert ecoregion of mid-western Argentina
BACKGROUND The eco-epidemiological status of Chagas disease in the Monte Desert ecoregion of western Argentina is largely unknown. We investigated the environmental and socio-demographic determinants of house infestation with Triatoma infestans, bug abundance, vector infection with Trypanosoma cruzi and host-feeding sources in a well-defined rural area of

3. A simple, biologically sound, and potentially useful working classification of Chagas disease vectors
Current working classifications of Chagas disease vectors rely on a loose mix-up of biological and operational matters. They are therefore confusing and ineffective. I propose a very simple classification that makes biological sense and can be operationally useful. It considers a four-level hierarchy of species (which can be native or non-native); population

4. Where do these bugs come from? Phenotypic structure of Triatoma infestans populations after control interventions in the Argentine Chaco
House re-invasion by native triatomines after insecticide-based control campaigns represents a major threat for Chagas disease vector control. We conducted a longitudinal intervention study in a rural section (Area III, 407 houses) of Pampa del Indio, northeastern Argentina, and used wing geometric morphometry to compare pre-spray and post-spray (re-infestan

5. Positive deviance study to inform a Chagas disease control program in southern Ecuador
Chagas disease is caused by Trypanosoma cruzi, which is mainly transmitted by the faeces of triatomine insects that find favourable environments in poorly constructed houses. Previous studies have documented persistent triatomine infestation in houses in the province of Loja in southern Ecuador despite repeated insecticide and educational interventions. We a

6. Intrusive versus domiciliated triatomines and the challenge of adapting vector control practices against Chagas disease
Chagas disease prevention remains mostly based on triatomine vector control to reduce or eliminate house infestation with these bugs. The level of adaptation of triatomines to human housing is a key part of vector competence and needs to be precisely evaluated to allow for the design of effective vector control strategies. In this review, we examine how the

7. The peri-urban interface and house infestation with Triatoma infestans in the Argentine Chaco: an underreported process?
Peri-urban infestations with triatomine bugs, their sources and their dynamics have rarely been investigated. Here, we corroborated the reported occurrence of Triatoma infestans in a peri-urban area and in neighbouring rural houses in Pampa del Indio, in the Argentine Chaco, and identified its putative sources using spatial analysis and demographic questionn

8. Vector control intervention towards interruption of transmission of Chagas disease by Rhodnius prolixus, main vector in Guatemala
In Guatemala, the Ministry of Health (MoH) began a vector control project with Japanese cooperation in 2000 to reduce the risk of Chagas disease infection. Rhodnius prolixus is one of the principal vectors and is targeted for elimination. The control method consisted of extensive residual insecticide spraying campaigns, followed by community-based surveillan

10. Risk of dengue occurrence based on the capture of gravid Aedes aegypti females using MosquiTRAP
We assessed the risk classification of dengue fever based on the capture of Aedes aegypti adults using MosquiTRAP, a type of sticky trap, in comparison with traditional larval infestation indices. A total of 27 MosquiTRAPs were installed, with one trap per block, and were inspected weekly between November 2008-February 2009. Infestation baseline data were ob

Soropositividade para Brucella canis: sinais clínicos e fatores associados à infecção em cães atendidos em um centro de diagnóstico por imagem da cidade do Rio de Janeiro. / Seropositivity to Brucella canis: Clinical Signs and Factors Associated with Infection in Dogs Admitted to an Image Diagnosis Center in the City of Rio de Janeiro
The aims of this study were to analyze the clinical signs and factors associated with the seropositivity to Brucella canis in dogs admitted to a veterinary diagnosis center in the city of Rio de Janeiro. Serum samples were collected from 841 dogs, whose participation in the study was allowed by their owners. The samples were analyzed by the Agar Gel Immunodi

12. Current epidemiological trends for Chagas disease in Latin America and future challenges in epidemiology, surveillance and health policy
Chagas disease, named after Carlos Chagas, who first described it in 1909, exists only on the American Continent. It is caused by a parasite, Trypanosoma cruzi, which is transmitted to humans by blood-sucking triatomine bugs and via blood transfusion. Chagas disease has two successive phases: acute and chronic. The acute phase lasts six-eight weeks. Several
