  • Our ‘killer’ cells’ role in life-long flu vaccine

    19 February 2019 - The University of Melbourne

    Dr Nerissa Hannink

    In the battle against the flu, our ‘killer’ immune cells are like the body’s border control. These microscopic killers are white blood cells that can maintain a memory of previous exposure to a flu strain. And if they recognise an invader, these cells start an immune response to target and kill off the virus – stopping the infection. But the problem is that there are three types of influenza virus that can infect humans – strains A, B and C. They circulate in the human population globally, and mutate every flu season.

    Scientists have identified how deadly bacteria resist antibiotics at a molecular level for the first time, in a discovery that could have significant implications for the development of much-needed new drugs. According to a report published in Nature Scientific Communications this week, bacteria develop stronger cell membranes as they become resistant, repelling antibiotics and preventing effective treatment.

    Persistence of antibiotic resistance genes in beef cattle backgrounding environment over two years after cessation of operation

    15 February 2019 - Plos One

    Via CIDRAP

    Getahun E. Agga et al.,

    Confined animal feeding operations can facilitate the spread of genes associated with antibiotic resistance. It is not known how cattle removal from beef cattle backgrounding operation affects the persistence of antibiotic resistance genes (ARGs) in the environment. We investigated the effect of cessation of beef cattle backgrounding operation on the persistence and distribution of ARGs in the beef cattle backgrounding environment.
