A temperature increase of this size would alter the biology and the ecology of many mosquito vectors and the dynamics of the diseases they transmit such as malaria. Changes in climate and global warming have significant influences on the biology and distribution of vector-borne diseases, parasites, fungi, and their associated illnesses ...
Reduction of fecal coliform in wastewater may require the use of chlorine and other disinfectant chemicals, or UV disinfection treatment. Such materials may kill the fecal coliform and disease bacteria. They also kill bacteria essential to the proper balance of the aquatic environment, endangering the survival of species dependent on those ...
P. multocida causes a range of diseases in wild and domesticated animals, as well as humans. The bacterium is found in birds, cats , dogs, rabbits, cattle, and pigs. In birds, P. multocida causes avian or fowl cholera disease; a significant disease present in commercial and domestic poultry flocks worldwide, particularly layer flocks and parent ...
As the summer season gets underway, a new report finds that many coastal U.S. waterways, including popular beaches for swimming, are contaminated with unsafe levels of fecal bacteria.
The incidence of this disease has nearly tripled in the last 70 years. Notable among the species of birds most heavily affected were house sparrows, great tits, and Eurasian blackcaps. Prior to 1990, when global temperatures were cooler than now, less than 10 percent of house sparrows (Passer domesticus) were infected with malaria. In recent ...
The bird flu outbreak has taken concerning turns, with more than 60 human cases confirmed. Experts outlined four signs that the virus is going in the wrong direction. Key warning signs about bird ...
The disease presents in two very different forms: acute and chronic. Birds with chronic avian cholera, more common in domestic fowl, exhibit prolonged illness with more localized infections. Chronic infection has been demonstrated in snow geese, and these individuals are believed to be long term migrating reservoirs for the disease.
Without immediate curbs, temperatures are set to follow the red track, and increase between 3.2 and 5.4 degrees Celsius by 2100. The green line shows how we can minimize warming if emissions immediately drop -- a highly unlikely scenario. Global fossil fuel and cement emissions, in gigatons of carbon dioxide
