Background: Gram-negative bacteria with quinolone resistance and extended-spectrum beta-lactamases (ESBLs) present significant treatment challenges. This study evaluated the prevalence and characteristics of quinolone resistance in Gram-negative strains, investigating the relationship between plasmid-mediated quinolone resistance (PMQR), ESBLs, and integrons.
Methods And Results: We collected 146 Gram-negative isolates from patients in three Palestinian hospitals.
1. Shiga toxin-producing (STEC) strains are associated with disease outbreaks which cause a public health problem. The aim of this study was to determine the frequency of STEC strains, their virulence factors, phylogenetic groups and antimicrobial resistance profiles in broiler chickens.

Article Synopsis
- * A study involving 119 bed bug samples found DNA from bacteria Rickettsia and Ehrlichia, showing strong genetic similarities to strains present in dogs and ticks from other countries.
- * This research is the first of its kind in Tunisia and emphasizes the importance of further exploring how bed bugs may contribute to the spread of these diseases.
Article Synopsis
- - The study focused on detecting Shiga-toxin-producing E. coli O157:H7 in diarrheic camels in Tunisia, collecting 120 fecal samples between January 2018 and April 2019.
- - Out of 70 E. coli isolates, 4 (5.7%) were identified as STEC O157:H7, with key genes for virulence and antibiotic sensitivity tests revealing their resistance patterns.
- - This research marks the first finding of E. coli O157:H7 in camels in Tunisia, emphasizing the need for regular screening programs in food-producing animals to manage foodborne pathogens effectively.
Antimicrobial resistance is one of the most serious threats to human and animal health. Evidence suggests that the overuse of antimicrobial agents in animal production has led to the emergence and dissemination of multidrug-resistant isolates. The objective of this study was to assess the rate of extended-spectrum beta-lactamase (ESBL)-producing in calf feces and to characterize their resistance genes for antibiotics like beta-lactams and colistin, but also to determine their virulence genes.
