Background And Objectives: Rv1733c is a latency antigen from , a probable integral-membrane protein with promiscuous T-cell and B-cell epitopes, making it a potential vaccine candidate against tuberculosis. This study aimed to clone and optimize the expression of recombinant Rv1733c in for purification.
Materials And Methods: Chemically synthesized coding sequence was cloned in pET-23a(+) followed by transforming BL21 (DE3) cells.
Background: Some genetic and phenotypic variables are associated among distinct microbial populations.
Objectives: The associations between multi-drug resistance (MDR) phenotypes, prevalence of antibiotic resistance integrons (ARIs), bla SHV, bla TEM and bla CTX-M gene carriage and genetic fingerprints of random amplified polymorphic DNA (RAPD), confirmed by pulsed field gel electrophoresis (PFGE), were investigated among extended-spectrum β-lactamases (ESBL)-producing nosocomial isolates of Klebsiella pneumoniae.
Materials And Methods: Susceptibility of 35 ESBL-producing K.
The present study describes integron mediated multiple antibiotic resistance in extended-spectrum β-lactamase producing clinical isolates of Klebsiella pneumoniae. One hundred and four clinical isolates of K. pneumoniae from two Iranian hospitals were screened for extended-spectrum β-lactamase production and susceptibility of the extended-spectrum β-lactamase producing isolates was determined to 17 antibiotics by disc diffusion.

All isolates were typeable by RAPD, while 3.6% of them were not typeable by PFGE.

Methods: 129 pediatric patients with CF were enrolled in this cross-sectional study. Microbiological cultures were performed based on sputum or pharyngeal swabs.
