Global 03/14/15 poughkeepsiejournal.com: by John Ferro – They come out at night. They have scary teeth. They have a weird name with an extra vowel most people don’t pronounce. And they are where Lyme disease goes to die. Say hello to the opossum, the American marsupial with a pointy nose and prehensile tail that dines on ticks like a vacuum dines on dust. (Most people drop the first vowel when speaking of ‘possums, but possums actually belong to a different species native to Australia.) . . . (T)iny adolescent ticks that carry Lyme disease bacteria are most active during the late spring months, typically May and even as early as April during warmer years. But whereas these ticks can be found in large numbers on mice, shrews and chipmunks, they are eaten in large numbers by opossum. Research led by scientists based at the Cary Institute of Ecosystem Studies in Millbrook placed different species into cages, covered them with ticks and waited for the biting arachnids to jump off. The scientists then counted how many survived. Opossums can eat or remove as much as 96 percent of the ticks that land on them.

Cary scientists are continuing to examine the correlation between the frequency of different types of mammals, and the infection rates of ticks found in the same area. The initial thought? Where foxes thrive, Lyme doesn’t. That’s because foxes are good hunters of the small mammals that serve as the most effective reservoirs of the Lyme pathogen. – For complete article see http://www.poughkeepsiejournal.com/story/tech/science/environment/2015/03/14/lyme-disease-opossum-ticks/70221442/ and for relative video about foxes see http://www.poughkeepsiejournal.com/videos/news/health/lyme-disease/2014/10/27/18000483/

EBOLA VIRUS:

ebola-virus32Maryland 03/12/15 medscape.com: by Robert Lowes – An American healthcare worker who has tested positive for the Ebola virus is expected to arrive tomorrow from Sierra Leone at an infectious-disease containment unit of the National Institutes of Health (NIH) in Bethesda, Maryland, the federal agency announced today. The American had been volunteering in an Ebola treatment facility in Sierra Leone, one of three nations bearing the brunt of the disease’s outbreak in West Africa since it began in December 2013. A chartered aircraft will transport the individual while in isolation to the Special Clinical Studies Unit (SCSU) at the NIH Clinical Center. The NIH did not release any further details about the identity of the American. The SCSU is one of a handful of high-level containment units in the country designed to treat patients with a virulent infectious disease such as Ebola and prevent further disease transmission. The healthcare worker, due to arrive tomorrow at the SCSU, will be the second patient with Ebola treated there. – See http://www.medscape.com/viewarticle/841408?src=wnl_edit_newsal&uac=218349HV

help7689Ontario 03/12/15 Grey Bruce Health Services: Officials are looking for the owner of a cat that bit a man in Owen Sound on Saturday. Staff at the health unit need to confirm that the cat, found in the 1500 block of 3rd Ave. E. at approximately 12:30 p.m., has had a current rabies vaccination. The grey cat was hiding under a vehicle and when the man reached under the vehicle to remove it, he was bitten. The cat is believed to be an indoor cat. If it is determined the cat has been vaccinated, the man can avoid post-exposure rabies treatment. Anyone with information about the incident is asked to contact the health unit at 519-376-9420. – See http://www.owensoundsuntimes.com/2015/03/12/health-unit-seeking-cats-owner
