CoQ10 and lycopene are isoprenoid compounds with nutraceutical and pharmaceutical benefits. In this study, the effect of concomitant lycopene biosynthesis on CoQ10 accumulation in transformed Escherichia coli DH5α was studied. A lycopene production pathway including geranylgeranyl diphosphate synthase (crtE), phytoene synthase (crtB), and phytoene desaturase (crtI) from Erwinia herbicola was co...

Bovine ephemeral fever (BEF) is an acute epidemic disease in cattle and water buffalo, spanning tropical and subtropical zones of Asia, Australia, and Africa. In recent years, BEF has been distributed in many provinces of Iran and caused economic losses. In this study the sequence encoding the G1 epitope of bovine ephemeral fever virus (BEFV) G glycoprotein was amplified by PCR, ligated into th...

Colibacillosis caused by avian pathogenic Escherichia coli (APEC) is an economic threat to the poultry industry throughout the world. Some of the virulence genes may enhance the ability of E. coli isolates to grow in the tissues of broilers. The APEC strains are assigned to a few distinct phylogenetic groups. The purpose of the present study was to detect the virulence genes a...

BACKGROUND:The bacterial contamination of fertile eggs isthe most common cause of embryonic death in ostrich hatcheryunits leading to financial loss in ostrich industry. OBJECTIVES:The aim of this research was to investigate the bacterialcontamination status, with emphasis on Escherichia coli, ofostrich hatcheries and the antimicrobial resistance profile ofisolated Escherichia coli. METHODS:Ato...

considering the emergence of antibiotic resistance, scientists are interested in using new antimicrobial agents in the treatment of infectious diseases including infections of the enteric systems. lactic acid bacteria have the great potential to produce antimicrobial compounds that inhibit and control pathogenic bacteria. the aim of this study was to determine the anti-bacterial and anti-adhere...

Objective(s) Extensive use of quinolones has been associated with raising level of resistance. In the current, we focused on assessing the prevalence of Escherichia coli resistance to quinolones and frequency of qnrA, qnrB and qnrS in non ESBLs (extended spectrum beta-lactamases) and ESBLs producing E. coli with blaSHV and blaTEM. Materials and Methods One hundred and fifty E. coli isolates ...
