Multidrug Resistance Gene Released By Chinese Wastewater Treatment Plants 111
MTorrice writes "In recent years, increasing numbers of patients worldwide have contracted severe bacterial infections that are untreatable by most available antibiotics. Some of the gravest of these infections are caused by bacteria carrying genes that confer resistance to a broad class of antibiotics called beta-lactams, many of which are treatments of last resort. Now a research team reports that some wastewater treatment plants in China discharge one of these potent resistance genes into the environment. Environmental and public health experts worry that this discharge could promote the spread of resistance."

Antibacterials don't 'weaken' the immune response. Your body will make whatever antibodies it can to the bacteria irregardless of whether you use antibiotics or not. The antibiotic, if used correctly, will stop / slow down the growth of the bacteria and allow the immune system to help clear the infection. The problem with too frequent or inappropriate use of an antibiotic is that is gives the bugs more chances to develop resistance to the drug.
