摘要：
The present study was undertaken to assess the efficiency of a typical semi-urban wastewater treatment plant in Eastern Cape Province of South Africa for the removal of Listeria pathogens in wastewater. The abundance of Listeria pathogens in the final effluent as well as their in vitro antibiogram characteristics was evaluated. Total Listeria counts ranged from 9.0 X 10(3) to 3.40 X 10(5)cfu/ml; 7.60 X 10(3) to 8.10 X 10(4) cfu/ml and 2.0 X 10(1) to 3.5 X 10(4) cfu/ml for mixed liquor, pre-chlorinated and final effluents respectively. The final effluents did not meet the standards limits for turbidity, EC, TDS, DO, COD, PO4 and Listeria abundance, but fell within recommended limits for pH, temperature and salinity after treatment. Listeria strains showed resistance to at least one antibiotic, multiple antibiotic resistances ranging from 2 to 7 antibiotics. The study showed that treated final effluents in South Africa could be an important source of resistant Listeria pathogens in the environment.
