Construction of an Expression Vector Containing Mtb72F of Mycobacterium tuberculosis.

Objective: Despite using the Bacille Calmette Guerin (BCG) vaccine, tuberculosis (TB) is still a worldwide disease that kills 2-3 million people each year. Developing a new and more effective vaccine is one way to possibly reduce the morbidity and mortality of TB. The Mtb72F vaccine is one of the important subunit vaccines applied in human clinical trials.

The Prevalence of TEM and SHV Genes among Extended-Spectrum Beta-Lactamases Producing Escherichia Coli and Klebsiella Pneumoniae.

Objectives: Production of extended-spectrum beta-lactamases (ESBLs) by enteric bacteria continues to be a major problem in hospitals and community. ESBLs producing bacteria cause many serious infections including urinary tract infections, peritonitis, cholangitis and intra-abdominal abscess. The aim of this study was to determine the prevalence of ESBLs producing Escherichia coli and Klebsiella pneumoniae bacteria isolated from clinical samples of patients attending Imam Reza and Ghaem University Hospitals, Mashhad, Northeast of Iran.

Construction and Evaluation of an Expression Vector Containing Mtb32C (Rv0125) of Mycobacterium tuberculosis.

Expressions of recombinant proteins for different applications are important objectives in molecular biotechnology; however, expression of some recombinant proteins is difficult. Several methods have been designed for expression of these proteins. The aim of this study was to construct a vector containing Mtb32C fragment of Mycobacterium tuberculosis (M.
