Geographies [spatial and temporal] of Malaria: a type case of relations between humans and other organismsAt Stanford I happened upon Robert Desowitz' The Malaria Capers : More Tales of Parasites and People, Research and Reality, which answers a number of the above questions very well. And here's a troll in Annie for books.?what's the history of understanding malaria?How do we find the history of geographies of malaria, and how do we deal with the complexity once found? Need to factor in subsequent medical knowledge...
?what were the big steps?
?what means to control (viz: draining the Pontine Marshes)
?drugs? other interventions [DDT, etc] and implications/effects?
?what does malaria DO in populations where it's endemic? And what happened (demographically) where malaria was 'controlled'?
The Big Question this example asks: ?what must be taken into account if one is going to intervene in natural systems?

Malaria is the most important insect-transmitted human disease, but progress in its control has been slow, especially in Africa where approximately 90% of the infections occur. Several factors have contributed to the problem. Parasites and vectors have developed resistance to antimalarial drugs and insecticides; differences in the biology of major malaria vectors preclude the development of simple, universally applicable strategies for malaria control; and the cost of available malaria-control tools often exceeds the public health resources in the most malarious parts of the world. New tools are desperately needed. Current efforts include the testing of tools such as insecticide-impregnated bed nets that could become available in the near term, as well as long-term projects such as the development of malaria vaccines and mosquito-targeted genetic control strategies. The success or failure of any of these approaches will depend ultimately on understanding the natural patterns of malaria transmission in the field.

The introduction of novel biochemical, genetic, molecular and cell biology tools to the study of insect immunity has generated an information explosion in recent years. Due to the biodiversity of insects, complementary model systems have been developed. The conceptual framework built based on these systems is used to discuss our current understanding of mosquito immune responses and their implications for malaria transmission. The areas of insect and vertebrate innate immunity are merging as new information confirms the remarkable extent of the evolutionary conservation, at a molecular level, in the signaling pathways mediating these responses in such distant species. Our current understanding of the molecular language that allows the vertebrate innate immune system to identify parasites, such as malaria, and direct the acquired immune system to mount a protective immune response is very limited. Insect vectors of parasitic diseases, such as mosquitoes, could represent excellent models to understand the molecular responses of epithelial cells to parasite invasion. This information could broaden our understanding of vertebrate responses to parasitic infection and could have extensive implications for anti-malarial vaccine development.

The current knowledge on genomes of non-falciparum malaria species and the potential of model malaria parasites for functional analyses are reviewed and compared with those of the most pathogenic human parasite, Plasmodium falciparum. There are remarkable similarities in overall genome composition among the different species at the level of chromosome organisation and chromosome number, conserved order of individual genes, and even conserved functions of specific gene domains and regulatory control elements. With the initiative taken to sequence the genome of P. falciparum, a wealth of information is already becoming available to the scientific community. In order to exploit the biological information content of a complete genome sequence, simple storage of the bulk of sequence data will be inadequate. The requirement for functional analyses to determine the biological role of the open reading frames is commonly accepted and knowledge of the genomes of the animal model malaria species will facilitate these analyses. Detailed comparative genome information and sequencing of additional Plasmodium genomes will provide a deeper insight into the evolutionary history of the species, the biology of the parasite, and its interactions with the mammalian host and mosquito vector. Therefore, an extended and integrated approach will enhance our knowledge of malaria and will ultimately lead to a more rational approach that identifies and evaluates new targets for anti-malarial drug and vaccine development.

mosquito resistance to insecticides. A strain of Anopheles gambiae, normally a major vector for human malaria in Africa, can
encapsulate and kill the malaria parasites within a melanin-rich capsule in the mosquito midgut. Genetic mapping revealed one major and
two minor quantitative trait loci (QTLs) for this encapsulation reaction. Understanding such antiparasite mechanisms in mosquitoes may
lead to new strategies for malaria control.
