Extreme heat and precipitation events, which are expected to increase in frequency and intensity due to climate change, are associated with increased risk of Salmonella infections, according to a study led by researchers from the University of Maryland School of Public Health. The study is the first to provide empirical evidence that Salmonella infections related to extreme weather events are disproportionately impacting those living in the coastal areas of Maryland.

A new study looks at how leaf litter in water influences the abundance of Culex pipiens mosquitoes, which can transmit West Nile virus to humans, domestic animals, birds and other wildlife. The study found that different species of leaf litter in standing water influence where Culex pipiens mosquitoes deposit their eggs, how quickly the larvae grow, how big they get and whether they survive to adulthood. Because the mosquitoes feed on bacteria that grow on leaf litter, the team also measured how native and non-native leaf species influenced bacterial abundance and diversity. The study is reported in the journal Parasites and Vectors.
