Scientists Cage Dead Zebras in Africa to Understand the Spread of Anthrax
Scavengers might not play as key a role in spreading anthrax through wildlife populations as previously assumed, according to findings from a small study conducted in Etosha National Park in northern Namibia.
Wildlife managers currently spend large amounts of money and time to control anthrax outbreaks by preventing scavengers from feeding on infected carcasses. The effort might be ill spent, according to results published in Applied and Environmental Microbiology by an international consortium of researchers led by Steven Bellan, an ecologist at The University of Texas at Austin.
Wildlife Health Bulletin - Snake Fungal Disease in the United States
Snake Fungal Disease (SFD) is an emerging disease in certain populations of wild snakes in the eastern and midwestern United States. While fungal infections were occasionally reported in wild snakes prior to 2006, recently the number of free-ranging snakes with fungal dermatitis submitted to the USGS National Wildlife Health Center (NWHC) and other diagnostic laboratories has been increasing.
Laboratory analyses have demonstrated that the fungus Chrysosporium ophiodiicola is consistently associated with SFD, but often, additional fungi are isolated from affected snakes. At this time, definitive evidence that C. ophiodiicola causes SFD is inconclusive. As its name implies, SFD is only known to afflict snakes.
To date, the NWHC has confirmed fungal dermatitis (or the suspected fungal pathogen in association with skin lesions) in wild snakes from nine states, including Illinois, Florida, Massachusetts, Minnesota, New Jersey, New York, Ohio, Tennessee, and Wisconsin. However, it is suspected that SFD is more widespread in the United States than is currently documented. Multiple species of snakes have been diagnosed with SFD at the NWHC (see attached figures), including northern water snake (Nerodia sipedon), eastern racer (Coluber constrictor), rat snake (Pantherophis obsoletus species complex), timber rattlesnake (Crolatus horridus), massasauga (Sistrurus catenatus), pygmy rattlesnake (Sistrurus miliarius), and milk snake (Lampropeltis triangulum).

Humans Passing Drug Resistance to Wildlife in Protected Areas in Africa
A team of Virginia Tech researchers has discovered that humans are passing antibiotic resistance to wildlife, especially in protected areas where numbers of humans are limited.
In the case of banded mongoose in a Botswana study, multidrug resistance among study social groups, or troops, was higher in the protected area than in troops living in village areas. The study also reveals that humans and mongoose appear to be readily exchanging fecal microorganisms, increasing the potential for disease transmission.
Rabies Detected in New Area of State
A wolf killed in late March this year after it closely approached a trapper around the Chandalar Lakes area has tested positive for rabies. Rabies had not previously been documented in this area south of the Brooks Range.
The Alaska Department of Fish and Game (ADF&G) is asking the public to report any wolves, wolverines, foxes or other wildlife acting abnormally to the nearest ADF&G office, and by sending an email to email@example.com. Animals with rabies might be fearless in approaching people, attack inanimate moving objects, or be unable to run or move normally, said Dr. Kimberlee Beckmen, wildlife veterinarian with the department.
