Phylogenetic analysis and characterization of hybrid enteroaggregative/uropathogenic Escherichia coli strains isolated from urinary tract infection.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHybrid EAEC/UPEC Escherichia coli strains are emerging uropathogens that combine intestinal and extraintestinal virulence traits through horizontal gene transfer. Although relatively uncommon, these hybrids exhibit strong biofilm formation, enhanced epithelial adherence, and notable antimicrobial resistance, underscoring the need for detailed molecular characterization and epidemiological assessment. The present study aimed to determine the frequency of hybrid EAEC/UPEC isolates among E. coli recovered from patients with urinary tract infections and to characterize their lineage using PCR-based sequence type screening, phylogenetic grouping, and antibiotic resistance profiling.
methodsThis study analyzed 199 archived E. coli isolates from UTI patients, assessing antimicrobial resistance, ESBL production, and virulence genes. PCR was used to characterize their lineage using PCR-based sequence type screening and phylogenetic grouping.
resultsAnalysis of 199 isolates identified 17 EAEC/UPEC hybrids (8.5%), predominantly from female patients and children. All hybrids carried aatA, fyuA, and fimH, with variable presence of aap, aggR, and chuA. High resistance rates were observed, with 94.1% classified as MDR and 47.1% as ESBL producers. bla
conclusionsThis study identified 8.5% of urinary E. coli isolates as hybrid EAEC/UPEC strains. High multidrug resistance, particularly to trimethoprim-sulfamethoxazole, nalidixic acid, and cefotaxime, underscores major therapeutic challenges. These findings highlight the clinical importance of emerging hybrid pathotypes and the need for strengthened molecular surveillance.
