*3.2. MRSA*

Three MRSA isolates from three different activated sludge samples were detected. All three isolates harboured the mecA gen but were tested negative for PVL. Spa typing revealed one t032, with resistance to erythromycin, norfloxacin and gentamycin and one t067 with resistance to erythromycin, clindamycin and norfloxacin. The third MRSA with spa type t6613 was susceptible to all tested non beta-lactam antibiotics (Table 1).
