SIUSLAW NEWS ❚ WEDNESDAY, JANUARY 6, 2016 3 B Discovery of new bacteria complicates salmon poisoning CORVALLIS — Researchers at Oregon State University have identified for the first time another bacterium that can cause symptoms simi- lar to “salmon poisoning” in dogs — and may complicate the efforts of Pacific Northwest pet owners to keep their dogs protected and healthy. The Pacific Northwest, from northern California to central Washington, is the only region of the world in which dogs face this potentially deadly health threat. It’s caused by a compli- cated life cycle that includes a common freshwater snail that harbors a fluke worm, and the fluke, in turn, carries the bac- terium Neorickettsia helminthoeca. The bacterium is the actual cause of salmon poisoning. The underlying problem is not new. Dogs that died after eating uncooked, infected salmon were first noted in the Astoria Journal in 1814, not long after Lewis and Clark vis- ited the region. The conventional wisdom, however, has been that dogs are usually immune to salmon poi- soning after they have once been infected, treated with antibiotics and recovered — giving pet owners at least some assurance that it’s a problem they no longer need be con- cerned about. The new discovery makes it clear the issue is not that sim- ple. In the infectious process that leads to salmon poisoning, the fluke is released from snails, which then infect salmon and other freshwater fishes. The life cycle is completed when a mammal eats an infected fish — in this case, dogs get sick from eating raw or under- cooked salmon. The possible occurrence of “salmon poison- ing” is actually dictated by the geographic distribution of the snail. Another bacterium called “SF agent,” however, has been found for the first time in a salmonid fish anywhere in the world, researchers report in a recent study in Veterinary Parasitology. The fluke host for this bac- terium is Stellanchasmus falca- tus. “SF agent can infect dogs that eat salmon or trout, and it can cause a mild fever in dogs and other symptoms that can resemble salmon poisoning,” said Michael Kent, a professor of microbiology in the OSU College of Science and College of Veterinary Medicine, and co- author of the study. “It can also be treated with antibiotics, but may not offer immunity to dogs that could be later exposed to the actual salmon poisoning bacterium. “A pet owner might believe their dog is protected, when it isn’t.” The larval stages of the worm that carries Neorickettsia helminthoeca were first associ- ated with the disease in 1911, and in 1950 the actual bacteri- um was confirmed as the cause of salmon poisoning. It’s in the same bacterial family as SF agent – meaning pet owners must now understand their dogs may face two related Neorickettsia pathogens — but one causes only a mild illness, while the other can be deadly. Veterinary doctors, Kent said, routinely have treated ani- mals based on their clinical signs, because the eggs of the fluke may be hard to find in dog feces, and the bacterium is difficult to culture from dog blood. Left untreated, dogs with salmon poisoning can die in a week to 10 days, often from severe hemorrhaging and inter- nal ruptures. The ultimate fatal- ity rate can approach 90 per- cent of untreated cases. The bottom line, he said, is that pet owners should not make any assumptions about whether or not their dogs may have immunity to salmon poi- soning. Kent said he has received several reports from local veterinarians document- ing dogs contracting salmon poisoning more than once. With the new awareness that different bacteria can cause similar initial symptoms, pet owners should know that dogs displaying such symptoms may or may not have a serious health problem. The fluke worm, but not the bacterium, can also infect humans. Humans do not con- tract salmon poisoning, but may develop a relatively mild gastrointestinal illness. Either freezing or cooking infected fish will kill the worms. This research was supported by the National Institutes of Health and done in collabora- tion with researchers from the University of North Dakota, Georgia Southern University, and the Woodburn Veterinary Clinic in Woodburn, Ore. Eclipse The eclipse will begin at 9 a.m. and end at 11:30 a.m. on Aug. 21, 2017. The 60-mile wide path of totality — when the moon completely blocks the sun — will last for about two minutes starting at 10:15 a.m. on the coast between Newport and Lincoln City. The path of totality then sweeps through the state and on to Idaho, then runs across the United States toward South Carolina.

For the Viking boys, it was a mere three points that allowed Marshfield to edge out Siuslaw for second place, 50 to 53. North Bend won the Far West team title with 41 points, qualify- ing the Bulldogs, along with the Pirates, for today’s state meet in the team division. However, the Viking boys will still be represented thanks to sen- ior Jack Pickell, who ran a per- sonal best (17 minutes, 11 sec- onds) at district to finish fourth and qualify individually for state. The varsity girls race will start at 11:15 a.m., followed by the boys race at 11:50 a.m. Results will be available after each race at www.osaa.org/activ- ities/bxc. river as the season progresses. Parking can be limited at Knight Park during the fall salmon return. Anglers are reminded that from Knight Park boat ramp to Sulphur Creek from Sept. 1 to Dec. 31, angling is restricted to single point hook metal lures, fly angling, or salmon bobber angling. SILETZ RIVER: Steelhead, Chinook The Siletz River and bay is open for Chinook salmon. Fishing is slow. Fish are throughout the bay and river. Trolling herring in the lower bay is an effective technique. Eggs and bobber or drifting eggs can be productive in the upper bay and river as the sea- son progresses. Consult the regulations for changes in deadline locations through the season. Steelhead fishing is slow. The majority of the summer steelhead are in the upper Siletz gorge. Casting spinners, drifting bait or using a bobber and jig can be effective. For cutthroat trout, casting small spinners, spoons or fly fishing streamers or dry flies can be very effective. YAQUINA RIVER : Chinook The Yaquina River and bay is open for Chinook salmon. Fishing is slow. Fish are throughout the bay and river to the angling deadlines. Trolling herring in the lower bay is an effective technique. Eggs and bobber can be pro- ductive in the upper bay and river as the season progresses. For cutthroat trout casting small spinners, spoons or fly fishing streamers or dry flies can be very effective. from 1B oregonstateparks.org, and 8 a.m. by phone at 1-800-452- 5687.

Due to extremely low water levels, Lower Empire Lake was not stocked. Trout that were destined for Lower Empire Lake were stocked into Upper Empire and Butterfield lakes. Currently fishing for trout has been decent in the deeper lakes like Eel Lake. Anglers are having success slowly trolling wed- ding rings. TENMILE BASIN: Trout, bass, yellow perch, coho Trout angling in the streams of the Tenmile Basin are now closed until May 22, 2017. Trout fishing in Tenmile Lakes is open all year. There is no wild coho fish- ery in Tenmile Lakes this fall. Largemouth bass fishing has been good over the past month. Siuslaw News + www.shoppelocal.biz
