Since the turn of the century, certain parasitic diseases of livestock have frus trated efforts to bring them under control by vaccination techniques; East Coast fever and trypanosomiasis are two such diseases. East Coast fever (ECF) kills a half million cattle annually; and 3 million are killed each year by trypanosomia sis, which is widely spread over tropical Mrica. Together, these diseases have closed some 7 million square kilometers of land to livestock grazing-land that might otherwise support an additional 120 million head of cattle. In 1970 W.A. Malmquist of the U.S. Department of Agriculture, in collabora tion with K.N. Brown, M.P. Cunningham, and other associates at the East African Veterinary Research Organization in Kenya, succeeded in cultivating in vitro the protozoal organisms responsible for East Coast fever. This success, obtained utilizing tissue cultures, encouraged a number of organizations to support research on these parasites in an accelerated effort to develop field vaccines.

"The spread of parasitic diseases is a problem which faces most of the developing countries of the world. Many of the parasites of man do not cause obvious disease, but they do cause continual poor health. This book presents a study of the important parasites of man in Niugini. Its purpose is to achieve a scientific understanding of the causes of many of the parasitic diseases which afflict man, and to dispel the idea of witchcraft as the source and cure of these ailments. No disease-carrying parasite can be conquered unless man interferes with its life cycle. This can only be achieved when a large proportion of the population knows where, when, and how to do so effectively. Not only scientists, doctors, field and laboratory technicians and students, but all the people in the country must co-operate to understand and combat these diseases. The authors have outlined areas where future research should be carried out. A large part of the book is devoted to a study of malaria, an ever-present problem in Niugini. The high incidence of malaria causes continual poor health and decreased productivity. The information contained in this book is of local interest and is written in a language which can be easily understood by most people."--BOOK JACKET.

Los efectos negativos que los parásitos tienen sobre la eficacia biológica de sus hospedadores hacen del parasitismo uno de los principales agentes evolutivos. Por esta razón, conocer los factores que determinan la distribución espacial y temporal del impacto de los parásitos es crítico para anticiparnos a los problemas que las enfermedades emergentes pueden provocar en un contexto de cambio climático. Esta tesis emplea la curruca capirotada Sylvia atricapilla (Aves: Sylviidae) y sus parásitos sanguíneos hemosporidios (géneros Plasmodium, Haemoproteus y Leucocytozoon; Apicomplexa) como modelo de estudio para examinar cómo diversas fuentes de variación ambiental determinan las diferencias en el impacto de los parásitos. Se identificaron primero qué variables tienen mayor importancia en un contexto ibérico como determinantes de la diversidad de parásitos, encontrándose que si bien las variables ambientales (temperatura principalmente) son las más importantes, los modelos mejoran significativamente si se incluyen variables orográficas. Se usaron luego estos datos para examinar la distribución actual y la esperada a finales del S. XXI bajo tres escenarios de cambio climático de las zonas sujetas a un mayor impacto de estos parásitos en la Península, evidenciándose una reestructuración futura del mosaico actual de relaciones entre parásitos y hospedadores. Se realizó también una reconstrucción de cómo han evolucionado diferentes estrategias de transmisión estacional (transmisión estival, transmisión estival expandida y transmisión continua) a lo largo de la historia evolutiva de estos parásitos, encontrándose que paradójicamente la estructura ecológicamente más exitosa (transmisión continua) no es la más exitosa a largo plazo (transmisión estival). Finalmente, examinando las comunidades de parásitos de las currucas de Canarias y Madeira se descubrió que las relaciones parásito-hospedador habituales se ven comprometidas en ambientes insulares, y de que los síndromes insulares del parasitismo (riqueza baja, frecuentes cambios de hospedador y tendencia al generalismo) pueden desarrollarse incluso en la ausencia de aislamiento completo.

Investigation on the prevalence of blood-parasites in the hyperthermic pet dogs of Kathmandu Valley was carried out from September 2009 to December 2009. A total of 50 blood samples were collected from different clinics and hospitals of Kathmandu Valley and tested for blood parasites. The RBC, WBC, PCV, Hb, DLC of each sample were also assessed and analyzed. Data was analyzed to determine prevalence of various species of blood parasites to establish the correlation of these infections with age, sex and breed. An overall prevalence of blood-parasites was recorded as 14 %; Babesia canis, B. gibsoni and Ehrlichia spp being 8.00%, 2.00% and 4.00 % respectively. The percentage of infection was greater in males (12%) than females (2%). High occurrence was encountered in German shepherd breed of dog (85.71%) and rest (14.29%) was found in Japanese Spitz. The prevalence of blood parasites was found to be greater in the higher age group of canine population.

This book reviews flow cytometric methods (techniques for measuring and sorting of cells) used in hematology--ranging from those in routine use (such as leukocyte counting and immunophentotyping in diseases like leukemia and AIDS) to those that have potential future use in experimental and clinical hematology. This volume will be of interest to a wide audience, including cell biologists, hematologists, cancer researchers, and HIV/AIDS researchers.
