Survival of Enteroaggregative Hemorrhagic E coli(EAHEC)O104∶H4 and Monophasic Variant(O4,5,12∶1:-)of Salmonella Typhimurium in Organic Fertilizer such as Sewage Sludge,Slurry and Biogas Plant Effluents during Storage and Heat Inactivation

摘要

This paper describes investigations about the tenacity of enteroaggregative hemorrhagic Escherichia coli (EAHEC)serotype 0104∶ H4 and monophasic variant O4,[ 5 ],12∶I:-of Salmonella enterica serovar Typhimurium in organic fertilizers,such as sewage sludge,slurry and biogas plant effluents.In detail the investigations included experiments about the survival of both pathogens during storage of these fertilizers over month at IOoC and experiruents concerning their heat inactivation.The experiments are running and further results are still pending.Finally the studies should deliver information about the tenacity of tested bacteria,especially about the "new" enteroaggregative EAHEC serotype O104∶H4.The knowledge about the survival of pathogenic bacteria in organic fertilizer and their heat resistance can be used to estimate risks in use of these fertilizers on agricultural areas and optimize biotechnological treatments.
