Oral sex is now the leading risk factor for throat cancer, says researcher

Over the past two decades, there has been a rapid increase in throat cancer in the west, to the extent that some have called it an epidemic. This has been due to a large rise in a specific type of throat cancer called oropharyngeal cancer (the area of the tonsils and back of the throat). The main cause of this cancer is the human papillomavirus (HPV), which are also the main cause of cancer of the cervix. Oropharyngeal cancer has now become more common than cervical cancer in the US and the UK.

Colistin-resistant E. coli gains resistance to innate human immunity

Researchers from the University of Oxford, U.K., have investigated the evolution of antibiotic resistance properties of antimicrobial peptides (AMPs). In the paper “The evolution of colistin resistance increases bacterial resistance to host antimicrobial peptides and virulence,” published in eLife, researchers detail a disturbing discovery of how a specific type of antimicrobial agent, colistin, could be training E. coli and possibly other pathogens to evade the human immune system better.
