Both animal welfare and conservation are ethical imperatives, but what promotes one does not inevitably advantage the other. That’s one among the many items that we’re learning as we work to conserve and look after chimpanzees. The prevalence of drug-resistant staph in sanctuary chimpanzees may also pose a risk to human beings, Gillespie says, because of the close genetic romantic relationship between primates and folks. The chimpanzee may serve as an incubator where the pathogen can adjust and evolve, and leap back to humans in a more virulent form perhaps, he says.In some cases, antibiotics encourage bacterial biofilms to create even. Lu and senior writer James Collins, professor of biomedical engineering at BU, try to eradicate these biofilms using bacteriophage, tiny infections that attack bacteria. Phage have always been found in Eastern Russia and European countries to treat illness. For a phage to work against a biofilm, it must both attack any risk of strain of bacterias in the film and degrade the film itself. Recently, a different band of researchers discovered many phages in sewage that match both requirements because, among other activities, they carry enzymes with the capacity of degrading a biofilm’s extracellular matrix.
