Antibiotic resistance impacting wildlife

Bottlenose dolphins and humans have a lot in common…at least when it comes to developing resistance to antibiotics. After looking at over 700 pathogens collected from 171 wild Bottlenose dolphins captured in the Indian River Lagoon in Florida, researchers discovered that 88.2% of the pathogens were resistant to at least one antibiotic. The pathogens were especially resistant to erythromycin (91.6%) and ampicillin (77.3%). The animals were likely exposed to antibiotics […]

Polar bears (Ursus maritimus) living near the southern Beaufort Sea are spending more time on land during the summer months than in years past as a result of climate change and melting sea ice. Researchers wanted to know whether bears that spent more time on land were exposed to more pathogens compared to those who spent more time on sea ice.¬†Their results, published in the journal¬†Physiological and Biochemical Zoology, showed […]
