Abstract

• The present work was conducted to study the status of some indigenous bacterial species in wastewater from factories of noodles, confectioneries and rice vermicelli in Hlaingtharya industrial zone near Yangon city of Myanmar. The study was done from June to August, 2017 for preliminary studied. All samples were showed Escherichia coli positive on 3M petriflim. Among them, four E.coli isolates were tested for their antibiotics susceptibility patterns with Ampicillin and their generation time were studied. All E.coli isolates showed ampicillin resistance and generation time was between 20 to 22 min. Subsequently, genomic DNA and plasmid DNA profiling those antibiotics resistant Escherichia coli strains was done for future reference in further works on pollution estimation in this industrial zone.
