conclusions according to the results, six strains were resistant to six or seven antibiotics and all strains were at least resistant to two antibiotics. however, for each of these resistant bacteria one bacteriophage was isolated from environmental samples, which showed the effectiveness of bacteriophages to remove clinically resistant e. coli strains. effective phages in vitro showed effective...

the effects of dietary supplementation of garlic (allium sativum)extract on the growth and disease resistance of african catfish, clarias gariepinus was evaluated. also in-vitro evaluation of susceptibility of fish-borne multidrug resistant (mdr) pathogenic bacteria to aqueous extract of garlic was done. aqueous garlic extract exhibited inhibitory activity against mdr bacteria and the degree of...

enterococcus and lactococcus are gram-positive cocci that often occur in pairs ( diplococci ) or short chains, and are difficult to differentiate from streptococci on physical characteristics alone. enterococcus faecium because have concern antibiotic resistant, consider difficult as probiotic. the results of an assay show that a probiotic e. faecium strain might be a potential recipient of van...

Several heavy metal resistant bacterial strains were isolated from sediment and water samples collected from the Persian Gulf and enclosed industrial areas. All the isolated bacteria were identified by 16S rRNA gene sequencing. Isolated bacteria were tested for the presence of plasmids using the modified alkaline lysate method. The method was effective for identification and characterization of...

Background: The aim of this study was to investigate the frequency and type of bacteria resistant to chloramphenicol (CHL), erythromycin (E), and sulfamethoxazole (SXT) antibiotics from untreated wastewater effluents to receiving river. Methods: In total, 32 samples were taken from eight sites located in the raw wastewater to the downstream of the receiving Ghotor river in Khoy city. Resistant...

We investigate the chemical composition of aqueous and hydroethanolic extracts Stryphnodendron adstringens by evaluating total polyphenolic tannin contents, antioxidant activity as well marker compounds UHPLC-MS. Through in silico approach molecular pharmacokinetic parameters were predicted for two major substances found extract, pyrogallol (1) chlorogenic acid (2). The antibacterial was verifi...

Our study was designed to evaluate antibacterial activities of ethanol extracts from Croton macrostachyus and Justicia schimperiana bark leaf against certain bacterial pathogens such as E. coli O157 H:7 ATCC 25922, Salmonella Typhi 13311, Staphylococcus aureus 25923 Streptococcus pyogenes 196151. Qualitative quantitative methods were followed screen the phytochemicals in plants estimate total p...
