Malaria, the most common parasitic disease in the world, is transmitted to the human host by mosquitoes of the genus Anopheles. The transmission of malaria requires the interaction between the host, the vector and the parasite.The four species of parasites responsible for human malaria are Plasmodium falciparum, Plasmodium ovale, Plasmodium malariae and Plasmodium vivax. Occasionally humans can...
Sub-Saharan Africa suffers by far the greatest malaria burden worldwide and is currently undergoing a profound demographic change, with a growing proportion of its population moving to urban areas. Urbanisation is generally expected to reduce malaria transmission; however the disease still persists in African cities, in some cases at higher levels than in nearby rural areas. Objective. This pap...
Your publication of the assessment of Zambia’s National Malaria Control Program by Elizabeth Chizema-Kaweshia and others 1 documents successful outcomes using evidencebased Integrated Vector Management in Zambia. World Health Organization (WHO) recommendations and goals of the Global Roll Back Malaria Partnership contributed a proven framework for implementing Zambia’s national malaria control ...
background : malaria remains a serious public health problem with significant morbidity and mortal-ity. this study was conducted to identify whether ficolin-a could play an active role of against mala-ria infection. methods : the function of ficolin-a was analyzed in mouse model. the open reading frame of fico-lin-a was cloned from the liver of new born c57bl/6 mice by rt-pcr and then inserted ...
background: malaria is the most important vector-borne disease in many tropical countries all over the world. because of the widespread use of pyrethroid insecticide treated mosquito nets in the world, the effects of excito-repellency (er) phenomenon of pyrethroids against main malaria vector, anopheles stephensi were studied. methods: the er phenomenon of three concentrations of two synthetic ...
While the malaria outlook in recent years has either remained the same or shown improvement in some parts of South America, the number of reported malaria cases in certain parts of Middle America has continued to increase (I). The eighteenth report of the WHO Expert Committee on Malaria, published in 1980 (2), lists twelve constraints impeding the progress of antimalaria activities. These inclu...
BACKGROUND Robust malaria vector surveillance is essential for optimally selecting and targeting vector control measures. Sixty-two vector surveillance sites were established between 2005 and 2008 by the national malaria surveillance program in China to measure Anopheles sinensis human biting rates. Using these data to determine the primary ecological drivers of malaria vector human biting rate...
The reasons for the resurgence of malaria in the African highlands have been subject of debate. Because vector abundance is important for malaria transmission, gaining a better understanding of vector biology is a key to understanding the mechanisms of highland malaria. We studied vector productivity in relation to the highland environment and compared productivity between lowland and highland ...
BACKGROUND Community involvement has become an important component of the National Malaria Control Strategy in Kenya, resulting in the organization of groups charged with addressing mosquito and malaria-related concerns within the community. OBJECTIVES The purpose of this study was to identify community groups involved with intended malaria vector control activity in Malindi, Kenya. METHODS...
Malaria control is increasingly recognised as playing a key role in poverty reduction in high burdened countries. The programme for malaria eradication based on vector control using very large quantities of DDT started in 1949 in the country and resulted in a dramatic reduction in malaria incidence. Vector population recovery, mainly due to resistance to DDT in Anopheles populations as well as ...
