Comparison of in Vitro Activity of Doripenem versus Old Carbapenems against Pseudomonas Aeruginosa Clinical Isolates from both CF and Burn Patients.

Purpose: The antimicrobial activity of doripenem in comparison of imipenem, meropenem and ertapenem among Pseudomonas aeruginosa isolated from burn and Cystic Fibrosis (CF) patients were determined.

Methods: Metallo-β-lactamase (MBL) genes in imipenem non susceptible P. aeruginosa isolates were detected using PCR method.

Study of the carbapenem resistance mechanisms in clinical isolates of Acinetobacter baumannii: comparison of burn and non-burn strains.

We examined the prevalence of various carbapenem resistance mechanisms in clinical isolates of Acinetobacter baumannii collected from hospitalized burn and non-burn patients. Antimicrobial susceptibility testing was performed for 43 burn and 32 non-burn isolates. Carbapenem resistance genes were identified and repetitive extragenic palindromic PCR (REP-PCR) was used to define clonal relatedness.

Infection with Mycoplasma pneumoniae is not related to asthma control, asthma severity, and location of airway obstruction.

Background: Mycoplasma pneumoniae is an organism that reportedly has a strong relationship to asthma. However, asthma severity and location of airway obstruction have not been compared between asthmatic patients with and without evidence for remote mycoplasma infection.

Objectives: The aim of this research was to study the relationship between previous M.

Detection of metallo-β-lactamase-encoding genes among clinical isolates of Pseudomonas aeruginosa in northwest of Iran.

The prevalence of metallo-β-lactamase (MBL) production among 104 clinical isolates of Pseudomonas aeruginosa from northwest of Iran was investigated by phenotypic and polymerase chain reaction (PCR) methods. Thirty-nine (37.50%) of isolates were MBL positive by double-disk synergy test.
