To see if small mammalian predators influence tick infection rates, researchers placed camera traps at dozens of sites throughout Dutchess County in the summers of 2012 and 2013. Trap visitors included coyote, fox, bobcat, fisher, raccoon, and opossum. Then the investigators surveyed and tested ticks at the camera trap sites.
Locations with high predator diversity had lower infection prevalence of nymphal ticks than sites dominated by coyotes. Numbers of nymphal ticks were lowest where forest cover was higher, and bobcats, foxes, and opossums were associated with a reduction in tick infection.
The chlorine washing of food, the controversial “cleaning” technique used by many US poultry producers who want access to the British market post-Brexit, does not remove contaminants, a new study has found. The investigation, by a team of microbiologists from Southampton University and published in the US journal mBio, found that bacilli such as listeria and salmonella remain completely active after chlorine washing. The process merely makes it impossible to culture them in the lab, giving the false impression that the chlorine washing has been effective. Apart from a few voluntary codes, the American poultry industry is unregulated compared with that in the EU, allowing for flocks to be kept in far greater densities and leading to a much higher incidence of infection. While chicken farmers in the EU manage contamination through higher welfare standards, smaller flock densities and inoculation, chlorine washing is routinely used in the US right at the end of the process, after slaughter, to clean carcasses. This latest study indicates it simply doesn’t work.

Today’s WHO statement reflects 3 new cases, pushing the outbreak total to 44. There are now 3 confirmed cases, along with 21 suspected and 20 probable ones. Doctors Without Borders (MSF), which leads the clinical treatment arm of the response, said 23 deaths have been reported, an increase of 3 since the WHO’s last update.

Antibiotic resistance adds nearly $1,400 to the bill for treating a bacterial infection and costs the nation more than $2 billion annually, according to a study yesterday in Health Affairs.
The study, which is the first national estimate of the incremental costs for treating antibiotic-resistant infections, also found that the share of bacterial infections in the United States that were antibiotic resistant more than doubled over 13 years, rising from 5.2% in 2002 to 11% in 2014.
The potential risks associated with “toilet plume” aerosols produced by flush toilets is a subject of continuing study. This review examines the evidence regarding toilet plume bioaerosol generation and infectious disease transmission.
