Global 06/01/15 medicalexpress.com: Excerpts – “Northeastern University researchers have found that the bacterium that causes Lyme disease forms dormant persister cells, which are known to evade antibiotics. This significant finding, they said, could help explain why it’s so difficult to treat the infection in some patients.”

NEUniv.ggf643kjg6“In addition to identifying the presence of these persister cells, Lewis’ team also presented two methods for wiping out the infection—both of which were successful in lab tests. One involved an anti-cancer agent called Mitomycin C, which completely eradicated all cultures of the bacterium in one fell swoop. However, Lewis stressed that, given Mitomycin C’s toxicity, it isn’t a recommended option for treating Lyme disease, though his team’s findings are useful to helping to better understand the disease.

“The second approach, which Lewis noted is much more practical, involved pulse-dosing an antibiotic to eliminate persisters. The researchers introduced the antibiotic a first time, which killed the growing cells but not the dormant persisters. But once the antibiotic washed away, the persisters woke up, and before they had time to restore their population the researchers hit them with the antibiotic again. Four rounds of antibiotic treatments completely eradicated the persisters in a test tube.”

” Lewis and his colleagues presented their findings in a paper published online last week in the journal Antimicrobial Agents and Chemotherapy.” – For complete article see http://medicalxpress.com/news/2015-06-discovery-difficulty-lyme-disease.html

BLACK BEAR:

Seventeen-year-old Carly Hall of Belchertown tells The Daily Hampshire Gazette (http://bit.ly/1K44KMz ) she was walking a family friend’s dog with three other teens in Amherst on Saturday night when they encountered a black bear. The teens scattered, but the bear followed Hall, who had the dog on a leash. She let go of the leash when the bear got too close, and the dog ran. She says the bear scraped her back twice before she jumped on the roof of a parked car and the bear went after the fleeing dog. – See http://www.bostonherald.com/news_opinion/local_coverage/2015/06/massachusetts_teen_taken_to_hospital_after_bear_attack

Though she was reported to have the more serious form of the illness, neuroinvasive disease, she is now home recovering. – See article at http://krqe.com/2015/05/29/12-year-old-girl-diagnosed-with-first-human-case-of-west-nile-in-2015/

TULAREMIA (RABBIT FEVER):

tularemia.rr7788rr3New Mexico 05/29/15 Santa Fe County: Two rabbits found in the vicinity of the City of Santa Fe have tested positive for tularemia, a disease most commonly carried by rabbits and rodents in the wild. Pets such as dogs and cats often become infected. – See http://www.washingtontimes.com/news/2015/may/29/2-rabbits-from-santa-fe-area-test-positive-for-tul/

RABIES:

Henry County Animal Control supervisor Vince Farah said a rabies alert was issued Tuesday after multiple members of a family reported being bitten or scratched by a cat that later tested positive for the virus, according to multiple news outlets. Walter McElreath says he was scratched by the cat, which his family had interacted with for a few months, while trying to get it into a cage. All eight members of McElreath’s family, including six children, will begin rabies treatments in the next several days. – See http://wabe.org/post/henry-county-family-8-undergoing-rabies-treatments

South Carolina 05/29/15 Abbeville County: Four people have been referred to their health care providers for consultation after being exposed to rabies in (the city of) Abbeville by a sheep that tested positive for the disease, the Department of Health and Environmental Control reported today. The sheep was potentially exposed to an aggressive skunk, which was not available for testing, roughly one month ago. Three of the four victims provided routine husbandry care for the sheep. The fourth victim was potentially exposed on May 25, 2015. The sheep tested positive for rabies on May 27. – For complete article see http://thetandd.com/news/sheep-exposes-four-to-rabies/article_6dfdc8f5-c118-5b93-95fb-0970d8704d8c.html
