Abstract Chagas disease caused by Trypanosoma cruzi is a public health issue in Latin America. This highly diverse parasite divided into at least seven discrete typing units (DTUs) TcI-TcVI and Tcbat. Some DTUs have been associated with geographical distribution epidemiological scenarios clinical manifestations, but these aspects remain poorly understood. Many studies focused on studying the its vectors/hosts, using wide variety of genetic markers methods. Here, we performed systematic...
Reactivation of Trypanosoma cruzi transmission by native vectors with different domiciliation capabilities is a major concern for Chagas disease control programs . T. via intra-domestic Rhodnius prolixus was certified as interrupted the Pan American Health Organization in Miraflores municipality (Boyacá, Colombia) 2019. However, Triatoma venosa, vector infected has been increasingly found inside human dwellings across rural areas. In this study, aim to describe eco-epidemiological aspects...
Abstract Background Triatomines are hematophagous insects that play an important role as vectors of Trypanosoma cruzi , the causative agent Chagas disease. These have adapted to multiple blood-feeding sources can affect relevant aspects their life-cycle and interactions, thereby influencing parasitic transmission dynamics. We conducted a characterization feeding individuals from primary circulating triatomine genera in Colombia using amplicon-based next-generation sequencing (NGS). Methods...
Abstract Urban water bodies serve as critical reservoirs of microbial diversity, with major implications for public health and environmental quality. This study aimed to characterize the diversity surface waters wastewater from Pasto River in Colombian Andean Highlands, offering insights that may support quality monitoring efforts. Sampling was conducted at three river sites one location. Standard physicochemical microbiological analyses were performed, including real-time PCR detect...
Chagas Disease (CD), a chronic infection caused by the Trypanosoma cruzi parasite, is Neglected Tropical endemic to Latin America. With re-emergence in Venezuela during past two decades, spread of CD has proved susceptible to, and inhibitable digital, real-time surveillance system effectuated Citizen Scientists communities throughout country. The #TraeTuChipo (#BringYourKissingBug) campaign implemented January 2020, served as such strategy counting on community engagement define current...
Chagas disease (CD) is caused by the protozoan parasite Trypanosoma cruzi, and transmitted hematophagous insects of family Reduviidae. Psammolestes arthuri a sylvatic triatomine distributed in Colombia Venezuela which feeds on birds there are few studies that have reported Ps. naturally infected with T. cruzi. In Colombia, has been found dwellings, making it important to evaluate its possible role cruzi transmission cycle. We aimed presence feeding sources elucidate new scenarios country.A...
Triatomines (Hemiptera: Reduviidae) are the insect vectors of Trypanosoma cruzi , causative agent Chagas disease. The gut bacterial communities affect development T . inside vector, making characterization its composition important in understanding infection development. We collected 54 triatomine bugs corresponding to four genera different departments Colombia. DNA extraction and PCR were performed evaluate presence determine discrete typing unit (DTU) parasite. products 16S rRNA gene...
Trypanosoma cruzi, the causal agent of Chagas disease, is mainly transmitted by insects Triatominae subfamily. In Colombia, there are 26 triatomine species, and 16 them naturally infected with parasite. The parasite loads vectors can be significant in targeting specific species that affect epidemiology disease. Studying their ecology behavior vital to understand role T. cruzi transmission dynamics. We evaluated 182 field-collected triatomines corresponding 10 13 departments across Colombia....
Chagas disease is considered a public health issue in Colombia, where many regions are endemic. Triatoma dimidiata an important vector after Rhodnius prolixus , and it gaining importance Boyacá, eastern Colombia. Following the recent elimination of R . region, pivotal to understand behavior T transmission dynamics cruzi We used qPCR Next Generation Sequencing (NGS) evaluate infection, parasite load, feeding profiles, genotyping for specimens collected nine municipalities Boyacá explored...
Background Chagas disease, affecting approximately eight million individuals in tropical regions, is primarily transmitted by vectors. Rhodnius prolixus , a triatomine vector, commonly inhabits ecotopes with diverse palm tree species, creating optimal conditions for vector proliferation. This study aims to explore the transmission ecology of Trypanosoma cruzi causative parasite investigating feeding patterns and natural infection rates R . specimens collected from various wild species...
Chagas disease affects millions of people in Colombia and worldwide, with its transmission influenced by ecological, environmental, anthropogenic factors. There is a notable correlation between vector cycles the habitats insect vectors parasite. However, scale at which these operate remains uncertain. While individual triatomine ecotopes such as palms provide conditions for isolated cycles, recent studies examining blood sources various suggest more intricate network linking wild human...
Chagas disease (CD) is a parasitic zoonosis (Trypanosoma cruzi) that endemic in Colombia. Vector control of Rhodnius prolixus, the main domestic T. cruzi vector, has been achieved large part area with historically vector transmission CD. It necessary to understand ecological behavior characteristics local native vectors ensure sustainability programs. To evaluate long-term success recent campaign Boyacá department (Colombia), we used combined strategy entomological surveillance co-existing...
