Multiresistant Bacteria: Invisible Enemies of Freshwater Mussels

Freshwater mussels are among the most endangered groups of fauna anywhere in world. The indiscriminate use antibiotics has led to emergence resistant strains. These antibiotic-resistant bacteria play a key role increasing risk allied with surface water and spread resistance genes. Two freshwater mussel species, Margaritifera margaritifera Potomida littoralis, were sampled at 4 sampling sites along 50km stretch River Tua. Water samples taken same sites. Of total 135 isolates, 64.44% (39.26% from 25.19% mussels) coliform bacteria. Site T1, lowest concentration bacteria, site T2 only ones where M. was found. No E. coli isolates found this species pattern between similar. P. which present T3/T4 sites, is one that faces highest bacterial toxins, treated wastewater effluents around population centers. Sites have (water pattern, mainly β-lactams. littoralis (T3/T4) showed penicillins their combination clavulanic acid, cephalosporins, precisely fourth generation cephalosporin antibiotics. We discuss conservation status systems need for research into possible management measures. It suggested future studies on health bivalves should incorporate measures indicate bacteriological quality.
