Abstract Background: Escherichia coli is the most important and widespread bacteria in worldwide, which mainly found in contaminated food, human and animal faeces. Unfortunately, Some of E. coli strains are multidrug-resistant (MDR) pathogen leading significant public health concern globally. Biofilm is a multicellular community of microorganisms. Phages and their derivatives are ideal candidates for replacing or compensating for antibiotic problems in the future. Method: Here, we aimed to isolation and characterization of Escherichia coli phage and research its bactericidal activity that individually or collaborative with kanamycin sulfateResults: In this study, three virulent phages Flora, T4 and WJ were isolated from the laboratory and drug sample in Wuxi, China. It’s belonged to the Myoviridae family and optimum temperature is 42 ℃, optimum pH= 7, optimum MOI is 0.0001 and the genome size of Flora, T4 and WJ were 168, 909, 168903 and 168, 900 bp respectively. Flora has two exonuclease, whereas T4 and WJ have only one. Antibiotics have better bactericidal activity than phages in a low concentration medium of bacteria, nonetheless, phages have better bactericidal activity than antibiotics in a high concentration of bacteria, and that, collaboration of phages and antibiotics have better bactericidal activity effect than alone of phages or antibiotics in a low concentration medium of bacteria. Conclusion: The excellent performance of phage Flora for its therapeutic potential on clinic. The data of this study provided the strong evidence that the application of phage could reduce the growth and biofilm of E. coli that are important to maintain public health.

SummaryPlasminogen activator was isolated from disrupted pig leucocytes by the aid of DEAE chromatography, gel filtration on Sephadex G-100 and final purification on CM cellulose, or by preparative gel electrophoresis.Isolated plasminogen activator corresponds No. 3 band of the starting sample of leucocyte cells (that is composed from 10 gel electrophoretic bands).pH optimum was found to be in pH range 8.0–8.5 and the highest pH stability is between pH range 5.0–8.0.Inhibition studies of isolated plasminogen activator were performed with EACA, AMCHA, PAMBA and Trasylol, using Anson and Astrup method. By Astrup method 100% inhibition was found with EACA and Trasylol and 30% with AMCHA. PAMBA gave 60% inhibition already at concentration 10–3 M/ml. Molecular weight of plasminogen activator was determined by gel filtration on Sephadex G-100. The value obtained from 4 different samples was found to be 28000–30500.
