The poultry industry is a very important agricultural and industrial sector in Tunisia and Nigeria, with little information about occurrence of diarrheagenic Escherichia coli in the farmers and chickens. This study aimed to detect the prevalence of diarrheal E. coli in humans and poultry and to investigate plasmid-mediated quinolone resistance (PMQR) genes in both countries.

Article Synopsis
- Acinetobacter baumannii, a major nosocomial pathogen, has shown a worrying trend of high antibiotic resistance, specifically with six pandrug-resistant (PDR) strains identified in a Tunisian ICU, leading to one patient’s death and raising outbreak concerns.
- Environmental screenings revealed contamination of ICU equipment, including a respirator and hygiene supplies, further highlighting the risk of transmission.
- Genetic testing showed that all isolated PDR strains belonged to a pandemic clone (ST2) and harbored specific resistance genes, emphasizing the importance of systematic screening to control their spread in healthcare settings.
Antibacterial and antibiofilm activity of Peganum harmala seed extract against multidrug-resistant Pseudomonas aeruginosa pathogenic isolates and molecular mechanism of action.

Laboratory of Bioactive Substances, Biotechnology Center of Borj Cedria, BP-901, 2050, Hammam-Lif, Tunisia.
Article Synopsis
- * A study analyzed the antibacterial and antibiofilm effects of Peganum harmala seed extract, revealing that its n-butanol extract was more effective against drug-resistant strains than traditional antibiotics.
- * The active compound identified as harmaline demonstrated both strong antibacterial properties and significant biofilm inhibition, making it a promising candidate for treating P. aeruginosa-related infections.
Identification and characterization of multidrug-resistant ESBL-producing Salmonella enterica serovars Kentucky and Typhimurium isolated in Tunisia CTX-M-61/TEM-34, a novel cefotaxime-hydrolysing β-lactamase of Salmonella.

Aims: Molecular characterization of extended-spectrum β-lactamases (ESBLs) among Salmonella Kentucky and Typhimurium isolates: partial sequence analysis of the types of β-lactamases found in these isolates, clonality, resistance and supposed emergence of ESBL-producing strains.
Methods And Results: A retrospective study surveyed the ESBLs occurring in a total of 1404 Salmonella Kentucky and Typhimurium isolates collected over a 5-year period in Tunisia. Antimicrobial susceptibility tests, ESBL phenotype determination (double-disc synergy) were performed.

Aims: Characterization of quinolone-resistant Salmonella Kentucky and Typhimurium isolates in Tunisia from various sources, detection of some plasmid-mediated quinolone resistance genes and the genetic relatedness.
Methods: A total of 1404 isolates of S. Kentucky (n = 1059)/S.
