Disease monitoring in wildlife herds is critical to wildlife management and to identify potential zoonotic risks. New positive tests in Lancaster County, Pennsylvania, represent the latest in 46 positives since 2012. Although Chronic Wasting Disease (CWD) is a contagious fatal disease among deer and elk, research suggests that humans, cattle and other domestic livestock are … [Read more...]

Opinion – California raccoon distemper cases expose risks (includes video)
Cases of infected wildlife are not unusual. But, the human population encroachment into wildlife habitats has forced raccoons, skunks, coyotes and opossums to adapt to city living. In some areas, garbage cans, pet food dishes and potted gardens provide a more sustainable food supply than previous habitats. The result is an abundant, unbalanced critter population that inevitably … [Read more...]
7 things to know about Giardia in dogs
“Giardia is found in a lot of different locations,” says Tracey Jensen, DVM, Dipl. ABVP, founding partner of Wellington Veterinary Hospital in Wellington, Colorado. “Certainly, places where there is wildlife, particularly water fowl, or other dogs, so dog parks and places where there is standing water, can be areas where you can find quite a bit of giardia.” Giardia is not … [Read more...]

Rabies is still a public health issue
Despite that rabies continues to be a public health threat, some animal health pros fail to recognize its persistence. Vaccination alone is not the "silver bullet" for continued control of this nearly 100 percent fatal disease. If vaccination is the foundation of rabies control, then animal control is the cornerstone of it. Source: Vetted, April 14, 2017. Since the 1960s … [Read more...]
U.S. Court of Appeals puts gray wolf back on endangered list

Speaking of tapeworms
Sometimes there’s more to the human-animal bond than we want to admit. More interactions with wildlife as our cities expand into their habitat increase opportunities for new challenges, including a wide variety of Echinococcus spp. tapeworms. Dogs act as an intermediate host between wildlife and humans in some species. Source: Clinician’s Brief, July 2017. Surveillance in … [Read more...]
Deer steal feed in summer, create TB infection possibilities
“Isn’t she just so cute,” is not the best statement when seeing a doe and twin fawns eating farm-stored feed on an early August morning. Deer movements studied by scientists with USDA National Wildlife Research Center and Michigan State University showed more visits by deer to farm-stored feed in December and January than in the fall or spring. But, what stood out in the data … [Read more...]
Human noise pollution is disrupting parks and wild places
Human-caused noise has consequences for wildlife, entire ecosystems and people. It reduces the ability to hear natural sounds, which can mean the difference between life and death for many animals, and degrade the calming effect that we feel when we spend time in wild places. Source: The Conversation, July 17, 2017. Strategies to reduce noise include establishing quiet … [Read more...]
Fungal disease threatens wild and captive snakes
More than a dozen species of captive and wild snakes in at least 15 states have been affected by what’s being called snake fungal disease (SFD). Researchers are exploring the disease, including its epidemiology, how it grows, how it is transmitted, how to treat it and even which disinfectants work or don't work against the primary fungus associated with it, Ophidiomyces … [Read more...]
EPM continues to be a threat
Advances in diagnostics and treatments have greatly reduced the number of horses who succumb to Equine protozoal myeloencephalitis (EPM).

Plague still poses risks
The widespread impact of the “black death” is not likely to be repeated in our time. However, plague still poses substantial risk to exposed humans, including pet owners and veterinarians. Yersinia pestis, the cause of plague, is maintained in various wildlife populations, particularly wild rodents, and is spread through close contact and fleas. Spillover infections of domestic … [Read more...]

Texas expands fever tick quarantine zone
Fever ticks carry Babesia protozoa, which cause cattle fever. It is characterized by acute anemia, high fever, and enlargement of the spleen and liver, ultimately causing death for many infected cattle.

Screwworms in Florida after 30-year absence
Some of us have vivid memories of screwworm larvae burrowed into the flesh of livestock. A full-grown screwworm looks like any other fly. It is an insect small in size, dark, six-legged and compound-eyed. Its life cycle is quite different than other flies, however. A pregnant screwworm seeks out the bodies of much larger animals. Upon finding an open wound or other fleshy … [Read more...]
Cedar troubles
The disruptive invasion of cedar trees, such as eastern red cedar, blueberry juniper and redberry juniper, has become a major issue for rangelands, wildlife and landowners. While providing habitat benefits for some species, they push out other species. These invasive trees are also very thirsty. An acre of them absorbs 55,000 gallons of water per year. One report indicated a … [Read more...]
