Conventional anti–malarial drugs (chloroquine, Artesunate, Quinine, Amodiaquine etc) are used by most malaria-endemic countries as first-line treatment for uncomplicated malaria. However, resistance plasmodium parasite against these conventional has necessitated the need herbal medicine alternative. So in this study, we formulate a mathematical model of malaria transmission two interacting popu...
Anopheles gambiae, the main mosquito vector of human malaria, is a challenging organism to manipulate genetically. As a consequence, reverse genetics studies in this disease vector have been largely limited to RNA interference experiments. Here, we report the targeted disruption of the immunity gene TEP1 using transgenic expression of Transcription-Activator Like Effector Nucleases (TALENs), an...
abstract background and purpose:vector-borne diseases such as malaria and leishmaniasis are still a public health problem in iran. one of the effective ways to prevent of these diseases is to improve the vector control program. we carried out this study for assessment managers of school knowledge, attitude and practice regarding vector control programs. materials and methods:a cross-sectional s...
Insecticide resistance might reduce the efficacy of malaria vector control. In 2013 and 2014, malaria vectors from 50 villages, of varying pyrethroid resistance, in western Kenya were assayed for resistance to deltamethrin. Long-lasting insecticide-treated nets (LLIN) were distributed to households at universal coverage. Children were recruited into 2 cohorts, cleared of malaria-causing parasit...
Vector-borne diseases such as malaria and dengue constitute a major obstacle to socio-economic development in much of the tropics and remain high on the list of priorities for the improvement of public health. Sadly, financial as well as logistical constraints prevent a rapid amelioration of this situation (Reducing risks, promoting healthy life 2002). Unlike other infectious diseases, vector-b...
Malaria is the leading cause of death in Kenya highlands. Malaria is a vector-borne disease and mosquito is the vector that transmits the parasites from infected people to others. Controlling mosquito larval habitats is important in eradicating malaria. Modeling the spatially distributed mosquito larval habitats is challenging. This study explores a mosquito habitat modeling approach, which int...
The role of Anopheles triannulatus as a local vector has not yet been defined for malaria-endemic regions of Colombia. Therefore, the aim of this work was to detect An. triannulatus naturally infected with Plasmodium spp., as an approximation to determining its importance as malaria vector in the country. A total of 510 An. triannulatus were collected in six malaria-endemic localities of NW and...
Insecticide-treated nets (ITNs) are among the three major intervention measures that have reduced malaria transmission in the past decade. However, increased insecticide resistance in vectors, together with outdoor transmission, has limited the efficacy of the ITN scaling-up efforts. Observations on longitudinal changes in ITN coverage and its impact on malaria transmission allow policy makers ...
The public health and economic significance of malaria is enormous, and its control remains a great challenge. Many established malaria control methods are hampered by drug resistance and insecticide-resistant vectors. Malaria control measures built around environmental management are non-toxic, cost-effective, and sustainable. However, there has been no comprehensive review of the literature o...
