Ticks then thrive on the rodents, which are poor groomers.
Studies suggest that larval ticks have a 50% chance of surviving when they feed on mice, but only a 3.5% chance on opossums.

Two Dead From Raw Milk Cheese Contaminated With Listeria

Unpasteurized milk is an important vehicle for transmission of pathogens, which include Brucella species, Mycobacterium bovis, Salmonella species, Listeria monocytogenes, Campylobacter species, Yersinia species, Coxiella burnetii, and Shiga toxin-producing Escherichia coli.

they’re food for fish and other insect predators and birds. They pollinate plants.

the biting midge, a tiny bloodsucker that can spread diseases to animals and filarial worms to humans.
Dina Fonseca, a professor of entomology at Rutgers University, is that the biting midge is the only known pollinator of cacao.

Fighting the ‘Cockroach of Mosquitoes’
The Zika-carrying Aedes aegypti species bites by day and hides indoors by night, making it hard to eliminate

Experts working to halt the spread of the Zika, dengue and chikungunya viruses face a stubborn foe in the main mosquito that transmits them, and some of the many methods under consideration for fighting them are stirring controversy.
The Aedes aegypti mosquito primarily responsible for spreading these diseases has been called “the cockroach of mosquitoes.” It thrives around people, particularly in the densely packed neighborhoods that are common in the tropics. It bites during the day and hides at night in dark corners,…

Long-term measles-induced immunomodulation increases overall childhood infectious disease mortality
Science 8 May 2015: Vol. 348 no. 6235 pp. 694-699
Michael J. Mina, et al.
Immunosuppression after measles is known to predispose people to opportunistic infections for a period of several weeks to months. Using population-level data, we show that measles has a more prolonged effect on host resistance, extending over 2 to 3 years. We find that nonmeasles infectious disease mortality in high-income countries is tightly coupled to measles incidence at this lag, in both the pre- and post-vaccine eras. We conclude that long-term immunologic sequelae of measles drive interannual fluctuations in nonmeasles deaths. This is consistent with recent experimental work that attributes the immunosuppressive effects of measles to depletion of B and T lymphocytes. Our data provide an explanation for the long-term benefits of measles vaccination in preventing all-cause infectious disease. By preventing measles-associated immune memory loss, vaccination protects polymicrobial herd immunity.
Bad Flu Season Overshadows Other Winter Miseries
January 17, 2013
Dr. Beth Zeeman says she can spot a case of influenza from 20 paces. It’s not like a common cold.
“People think they’ve had the flu when they’ve had colds,” Zeeman, an emergency room specialist at MetroWest Medical Center in Framingham, Mass., tells Shots. “People use the word ‘flu’ for everything. But having influenza is really a different thing. It hits you like a ton of bricks.”
Joachim Santos, a carpenter from Brazil in a nearby examining room, says he’s never been as sick in all his 57 years. “I worry that it’s going to get more serious and I could die,” he says.
Dr. Andrew Pavia, an infectious disease specialist at the University of Utah, says flu has certain hallmarks. “A classic case of flu starts off suddenly with high fever, maybe shaking chills, severe muscle and body aches,” he says. “It’s not uncommon for people to say their hair hurts, they hurt so badly.”
