“There are nymphs all over the place in Marin but very few as you come south of San Mateo and Santa Clara (counties). “It seems easier to collect nymphs north of San Francisco,” he said. Studies show that the longer a tick is on the body, the more the likelihood of disease increases, Salkeld and Paulson both noted. The danger is in the size, as larvae and nymphs can latch on and hang on for days at a time. Then they develop into nymphs, which Salkeld called “the obnoxious teenager stage.” Finally, they become large, identifiable adults. “Immature life stages, called nymphs, are really small like poppy seeds and come out in abundance in April through June.”Ī tick’s life cycle begins with larvae, which are comparable to babies and children. Adults … try to persist through the rainy season,” he said. Ticks are present in northern California year-round - just with different levels of abundance, Salkeld said. The pathogens studied were Borrelia burgdorferi, Borrelia miyamotoi and anaplasma phagocytophilum.
“For this study we looked at three different pathogens, (so) it just comes as a surprise when you notice that if you start looking across different pathogens, a much higher portion of ticks are infected,” Salkeld said. The locations and those like it were chosen by ecologists for the way they are widely used by the public this is how the county’s vector control agency studies and collects ticks too, manager Amanda Poulsen told the Sentinel. The scientist said he was also surprised by the number of ticks found in areas such as Santa Cruz County, but that readers who roamed the studied areas - Forest of Nisene Marks and Wilder Ranch State parks, to name a few - likely wouldn’t be. (Shmuel Thaler – Santa Cruz Sentinel file) That was, however, the case when Henry Cowell and other state parks were studied by Salkeld and his team. Redwoods, lead author of the study published by the American Society for Microbiology, were not often an area associated with those that could house infected ticks. So I would have assumed that disease would have been lower.” Redwoods reach for the sky in Henry Cowell Redwoods State Park last year. “If you go to the open coastal areas, the squirrel isn’t there. “That’s the classic kind of evolved picture of California Lyme disease ecology,” Salkeld said Friday. This is largely due to Western gray squirrels who make a home in the woods and transmit the infection. Places such as Mendocino County, he said, are a hot spot where scientists can regularly find infected ticks. Daniel Salkeld, the lead author of the study and research scientist at Colorado State University, said that a lot of the work on Lyme disease done by ecologists such as himself focuses on the woodland habitat. Without treatment Lyme disease can infect the joints, the heart and the nervous system most cases can be treated with antibiotics.ĭr.
SANTA CLARA COUNTY LAB TICK LYME TEST SKIN
Lyme disease, according to the Centers for Disease Control and Prevention, often shows up in individuals through fevers, headaches, fatigue and a skin rash. SANTA CRUZ - A recent study of coastal counties in Northern California, including Santa Cruz County, showed a surprising result to ecologists - Western black-legged ticks infected with pathogens that cause diseases such as Lyme disease roam the redwood forests and the coastal beaches, not just the woodlands.
