Mupirocin (pseudomonic acid A, or Bactroban or Centany) is an antibiotic originally isolated from Pseudomonas fluorescens. It is used topically, and is primarily effective against Gram-positive bacteria. Mupirocin is bacteriostatic at low concentrations and bactericidal at high concentrations. Mupirocin has a unique mechanism of action, which is selective binding to bacterial isoleucyl-tRNA synthetase, which halts the incorporation of isoleucine into bacterial proteins. Because this mechanism of action is not shared with any other antibiotic, mupirocin has few problems of antibiotic cross-resistance.
An affect of oil spills on penguins is that their feathers will  lose its way to insulate the body, resulting in hypothermia. The  birds may even swallow the oil when trying â¦ to clean their feathers  that could lead to poisoning.1 person found this useful.irds are effected by oil spills as well as fish, and the oil travels up the food chain. Krill and other food eaten by fish, or further down the food chain are also affected. Generally their populations are lowered, creating food shortages for fish.
Although Dr Kingston recommends that the polluted areas are cleaned quickly, he argues that animals are used to adapting to new conditions. The long-term effect of an oil spill is the subject of much debate among scientists.Some argue that animals and birds are harmed many years after the event, but others believe wildlife is more resilient.il spills, such as that of Brittany in 1999, can kill huge numbers of birds and animals. BBC News Online's Kate Milner examines oil spills to see how much damage they cause and whether and how well wildlife recovers.
