The species composition and abundance of the zooplankton community of seven reservoirs of the Paranapanema River, located between 22 degrees 37'-23 degrees 11'S and 48 degrees 55'-50 degrees 32'W, were analysed over four periods, in the year of 1979. The zooplankton community was composed of 76 species of Rotifera, 26 species of Cladocera and 7 species of Copepoda. For a large part of the perio...

Changes in nutrient concentrations groundwater were investigated to determine the impact of agriculture on water quality artificial lakes. The study covered three reservoirs an agricultural area Wielkopolska (central-western part Poland). Assessing required a network piezometers around reservoirs, used degree pollution from nutrients supplied reservoirs. Moreover, analysis streams flowing into ...

to improve our understanding of helicobacter  infection in cats and to determine whether they are reservoirs for h. pylori  and sources of zoonotic transmission to humans, we selected cats as an experimental animal model for gastric colonization by h. pylori. sixteen stray cats underwent helicobacter  eradication treatment followed by three consecutive oral inoculations of a cocktail of human h...

the recently emerged middle east respiratory syndrome coronavirus (mers-cov) emerged in the middle east region in 2012. the virus is phylogenetically related to bat cov, but other animal species like camels and goats may potentially act as an intermediate host by spreading the virus to humans. this virus is thought to cause a severe disease in patients with underlying comorbidities. laboratory ...

NEW CHALLENGES FOR PUBLIC HEALTH Emergence of new pathogens has been the reality of the 21st century; the role of animal reservoirs and changes in human behaviors may be the main key factors for disease dynamics. Human population growth and territory expansion have lead to habitat sharing between human beings, domestic animals, wild animals, and their pathogens; bringing new opportunities for s...

To study the relationships between the biomass of reservoir communities and to examine the differences between reservoirs with different fish assemblages, we used limnological and fish data for 31 Argentinean reservoirs. Despite conspicuous systemic differences with lakes, reservoirs dominated by visual zooplanktivorous fishes have had phytoplankton biomass drastically higher than reservoirs wi...
