this study was conducted to investigate hematophagic tendencies of the malaria vector based on a seasonal basis as well as by geographical region in a malaria endemic area in kahnouj, southern iran. this study was carried out for 14 months from apr/ 2002 up to the end of may 2003. female anophelines were collected from different shelters in hilly and plain regions of kahnouj district and their ...
BACKGROUND Malaria transmission is perennial in the Assam-Arunachal Pradesh interstate border areas in the Sonitpur district of Assam, India. A yearlong study was carried out on the incidence of symptomatic and asymptomatic malaria and the role of asymptomatic malaria carriers in persistent transmission of the disease. The relationships between malaria incidence and weather parameters were also...
Here we present a comprehensive review of the literature on the vectorial importance of the major Anopheles malaria vectors in Colombia. We provide basic information on the geographical distribution, altitudinal range, immature habitats, adult behaviour, feeding preferences and anthropophily, endophily and infectivity rates. We additionally review information on the life cycle, longevity and po...
Malaria is still one of the infectious diseases urgently requiring control and causes socioeconomic burdens on people residing in developing countries. Malaria vaccines are expected to control the disease. However, there is no effective vaccine available despite the intense efforts of malaria scientists. One strategy for a malaria vaccine is to prevent parasite spread by means of interfering wi...
Wolbachia pipientis bacteria are maternally inherited endosymbionts that are of interest to control the Anopheles mosquito vectors of malaria. Wolbachia does not infect Anopheles mosquitoes in nature, although cultured Anopheles cells can be infected. Here, we show that the virulent Wolbachia strain wMelPop can survive and replicate when injected into female Anopheles gambiae adults, but the so...
Wildlife on isolated oceanic islands is highly susceptible to the introduction of pathogens. The recent establishment in the Galápagos Islands of the mosquito Culex quinquefasciatus, a vector for diseases such as avian malaria and West Nile fever, is considered a serious risk factor for the archipelago's endemic fauna. Here we present evidence from the monitoring of aeroplanes and genetic analy...
In West and Central Africa endemic malaria and epidemic yellow fever are still main causes of morbidity and mortality. From Dakar in Senegal to Kinshasa in the Democratic Republic of Congo the pattern of malaria transmission shows a huge variability, in term of dynamics (rhythm and intensity) of transmission, as well as in terms of the vector species involved. The Plasmodium annual entomologica...
In India National Vector Borne Diseases Control programme is an umbrella organization for management and control of six out eight insect-borne human diseases, viz., Malaria, Lymphatic Filariasis (LF), Kala-azar, Dengue/ Chikungunya, Japanese Encephalitis. Of these, committed elimination the first three diseases from country. 8.6% India’s total population belongs to tribal community yet contribu...
Scale-up of the main vector control interventions, residual insecticides sprayed on walls or structures and/or impregnated in bed nets, together with prompt diagnosis and effective treatment, have led to a global reduction in malaria transmission. However, resistance in vectors to almost all classes of insecticides, particularly to the synthetic pyrethroids, is posing a challenge to the recent ...
