The part that is unconfined is the smaller recharge area. The Recharge Zone The Edwards aquifer is often referred to as a fault-zone aquifer because recharge in the recharge zone occurs because the limestone is heavily faulted and fractured as it follows the Balcones Fault Line.he Edwards is divided into three parts: the contributing zone, the recharge zone and the artesian zone. The aquifer is mostly confined, the contributing zone, which is the largest part,is confined below by a rock called Glen Rose Limestone and above by mostly impermeable Del Rio Clay.
Enteric diseases are infections that can be caused by viruses or bacteria entering the body through the intestinal system.
Enterococcus is a large genus of lactic acid bacteria of the phylum Firmicutes. Enterococci are Gram-positive cocci that often occur in pairs (diplococci) or short chains, and are difficult to distinguish from streptococci on physical characteristics alone.Two species are common commensal organisms in the intestines of humans: E. faecalis (90-95%) and E. faecium (5-10%).Rare clusters of infections occur with other species, including E. casseliflavus, E. gallinarum, and E. raffinosus.mportant clinical infections caused by Enterococcus include urinary tract infections, bacteremia, bacterial endocarditis, diverticulitis, and meningitis. Sensitive strains of these bacteria can be treated with ampicillin, penicillin and vancomycin.
