Pathology, Vector Studies, and Culture


Book Description

Malaria: Volume 2, Pathology, Vector Studies, and Culture is a collection of papers that deals with erythrocyte destruction mechanism in malaria, the pathology of malaria, colonization of laboratory mosquitoes, and their transmission of plasmodia. Other papers describe the culture of the invertebrate stages of plasmodia, of mosquito tissues, and also of erythrocytic and exoerythrocytic stages of plasmodia. One paper constructs a model to show the roles of the different destructive and regenerative processes in the mechanisms of erythrocyte destruction in malaria. Another paper describes the organ changes and physiopathological mechanism connected with Plasmodium infection. These organs concern the spleen, liver, heart, and vascular system. One paper reviews the procedures involved in malaria transmission by mosquitoes, as well as some specialized procedures unique in avian, rodent, simian, and human malarias. Another paper discusses the benefits and drawbacks of a culture medium based on the composition of adult anopheline hemolymph. This medium should lead to a rapid growth rate in primary cultures of mosquito cells and a shorter interval of adaptation for continuous cell lines. The collection can prove useful for pharmacologists, general medical practitioners, investigators, and laboratory technicians involved in mosquito borne diseases or tropical medicine research.




The Molecular Biology of Insect Disease Vectors


Book Description

Only one generation ago, entomology was a proudly isolated discipline. In Comstock Hall, the building of the Department of Entomology at Cornell University where I was first introduced to experimental science in the laboratory of Tom Eisner, those of us interested in the chemistry of life felt like interlopers. In the 35 years that have elapsed since then, all of biology has changed, and entomology with it. Arrogant molecular biologists and resentful classical biologists might think that what has happened is a hostile take-over of biology by molecular biology. But they are wrong. More and more we now understand that the events were happier and much more exciting, amounting to a new synthesis. Molecular Biology, which was initially focused on the simplest of organisms, bacteria and viruses, broke out of its confines after the initial fundamental questions were answered - the structure of DNA, the genetic code, the nature of regulatory genes - and, importantly, as its methods became more and more generally applicable. The recombinant DNA revo lution of the 1970s, the development of techniques for sequencing macromolecules, the polymerase chain reaction, new molecular methods of genetic analysis, all brought molecular biology face to face with the infinite complexity and the exuber ant diversity of life. Molecular biology itself stopped being an isolated diScipline, pre occupied with the universal laws of life, and became an approach to addressing fas cinating specific problems from every field of biology.




Expectations of Life


Book Description

Destined to become a classic epidemiological study, EXPECTA- TIONS OF LIFE surveys world mortality, describing and ex- plaining the declines of mortality which have become especi- ally evident in this century.







Traditional Medicinal Plants and Malaria


Book Description

Malaria is an increasing worldwide threat, with more than three hundred million infections and one million deaths every year. The worlds poorest are the worst affected, and many treat themselves with traditional herbal medicines. These are often more available and affordable, and sometimes are perceived as more effective than conventional antimala




Malaria


Book Description

Malaria: Volume 3, Immunology and Immunization is a collection of papers dealing with malaria parasites, the methods for measuring the immunological response to plasmodia, and the vertebrates host's immune response to plasmodia. Some papers discuss immunization against sporozoites, against the exoerythrocytic stages of malaria parasites, against asexual blood-inhabiting stages of plasmodia, as well as gamete immunization in malaria. One paper describes various separation methods to isolate malaria parasites and their constituents. Another paper discusses in detail the theory and practice of methods used in measuring antibody responses which occur during plasmodial infections, including the antibody response against sporozoites, exoerythrocytic forms, and in the different blood stages. Another paper explains the vertebrate host's immune response to plasmodial infection as a homeostatic physiological response changing along with the progression of the disease. The changes in the dynamic cellular cascade are different as the disease progresses causing death, than when these lead to recovery. Another paper enumerates the parameters which determine malarial infectiousness from one individual to another such as the time of onset, duration, intensity of the blood infections, as well as the maturity, longevity, and rate of production of gametocytes. Pharmacologists, general medical practitioners, investigators, and laboratory technicians involved in malarial research will find the collection very useful.







Avian Malaria Parasites and other Haemosporidia


Book Description

When studying the effects of parasites on natural populations, the avian haematozoa fulfills many of the specifications of an ideal model. Featuring a multitude of tables and illustrations, Avian Malaria Parasites and Other Haemosporidia summarizes more than a century of research on bird haemosporidians. For a long time, bird blood parasites served as important models in studying human diseases. Although now largely replaced, the wealth of data and research remain. With chapters addressing life cycles and morphology, pathogenicity, ultrastructure, geographical distribution, and illustrated keys to all known species of the parasites, this book is a masterful assessment of the biology of bird haemosporidian parasites.




Advances in Disease Vector Research


Book Description

Volume 9 in this series consists of four chapters on vectors that affect human or animal health and six chapters on plant pathogens and their vectors. In Chapter 1, Alex S. Raikhel discusses vitellogenesis in mosquitoes: the cornerstone of the reproductive cycle involving massive production of yolk precursors by the fat body and their accumulation in developing oocytes. In anautogeneous mosquitoes, vitellogenesis is dependent on the availability of a blood meal and, as a consequence, is linked to transmission of pathogens. Therefore, elucidation of mechanisms governing the mosquito vitellogenesis is critical for the successful development of novel strategies in vector and disease management. Previous reviews on mosquito vitellogenesis have dealt predominantly with hormonal control. The goal of this review, however, is to summarize significant progress which has been achieved in understanding mosquito vitellogenesis at the cellular, biochemical and molecular levels. It is with these disciplines that we expect to fully understand the mechanisms governing this key process in mosquito reproduction.
