Two epidemiological studies, designed to expand our knowledge of morbidity and
mortality indicators concerning malaria and Bacillus Calmette-Guerin vaccination in the
Hospital Albert Schweitzer health district located in Central Haiti's Artibonite Valley, are
presented. The hospital serves a rural population of 190,000 in its 610 square mile
district. A large...
The myxozoan parasite, Ceratomyxa shasta, is the most significant pathogen of juvenile Chinook salmon (Oncorhynchus tshawytscha) in the Klamath River, CA, USA. This parasite requires two hosts - a freshwater polychaete (Manayunkia speciosa) and a salmonid - to complete its life cycle. The complex life cycle and large geographic area...
The phantom midges (Diptera: Chaoboridae) are a relatively small fly family composed of 50 extant species in six genera. Larvae are of interest to limnologists and ecologists because of their tolerance to toxicants, predatory avoidance strategies, and the role chaoborids play in zooplankton community dynamics. Relative to mosquitoes, systematists have...
The rapid growth of aquaculture and concomitant growth in the use of compound aquafeeds have resulted in aquaculture using 35% of global fishmeal and 54% of global fish oil in 2000, up from just 10% and 16% respectively in 1988. Meanwhile, landings of reduction fish have hovered near 30 mmt,...
This study describes and quantifies some microprocesses of malaria
transmission including blood vessel location by Anopheles stephensi and
sporozoites delivery of An. stephensi infected by Plasmodium berghei. The
study models the effects of malaria parasite-induced changes in probing
behavior and mosquito mortality on disease transmisson. Finally, host, vector,
and parasitological...
