[Comparative study of antibiotic resistance in bacteria isolated from burned patients during two periods (2005-2008, 2008-2011) and in two hospitals (Hospital Aziza Othmana, Trauma and Burn Center)].

Background: Continuous monitoring of the bacterial flora and antibiotic resistance of the main bacteria involved in nosocomial infections helps improve treatment and prevention strategies.

Aim: To compare the bacteriological profile and antibiotic susceptibility of the main bacterial isolates within the burned patients over two periods of 3 years and in two hospitals.

Methods: During two three-year periods: period 1 (P1): 1/7/2005-30/6/2008 and period 2 (P2): 1/7/2008-30/6/2011) and in two hospitals: Hospital Aziza Othmana (HAO) and the traumatology and burn center (CTGB), 2153 and 3719 non-repetitive strains were isolated from burn patients from different samples.

[Epidemiological profile and antibiotic resistance of Pseudomonas aeruginosa isolates in burn and traumatology center in Tunisia over a three-year period].

Background: Pseudomonas aeruginosa is a known opportunistic pathogen frequently causing serious infections in burned patients.

Aim: To analyze the epidemiological profile of Pseudomonas aeruginosa isolated in a Tunisian burn unit.

Methods: During a 3-year period (from 01 July 2008 to 30 June 2011), 544 non repetitive strains of P.
