“…E. coli has already been isolated and detected in several parts of the world (Şeker & Yardimci 2008, Parvez et al 2017, Aijuka et al 2018, Maniha & Noor 2020. Studies on the characterization of this pathogen are little explored.…”

This study aimed to map the world's scientific production of bacterial and fungal microbiota in mollusks. The research was carried out in the Web of Science database, using "Fungi AND Mollusk" and "Bacteria AND Mollusk" descriptors and publication time between 2001 and 2021. Indexes were built by years, countries, research areas, and two maps of the co-occurrence of terms. There was a progressive increase in the production of microbiota in mollusks, with more research on bacteria during the investigated period. China and USA were the countries with the highest percentage of publications. Research with fungi and bacteria accounted for 28.41 and 17.66% in China, respectively. While the USA, the percentage was 21.05% for fungi and 16.02% for bacteria. Areas such as marine and freshwater biology (24.77%), fisheries (23.86%), biochemistry and molecular biology (18.60%), and pharmacy (17.83%) showed a higher percentage of indexed articles. There was also a high concentration of deposits of publications in the immunology area for both themes. The groups formed for bacteria and fungi indicated that studies had described the immune responses of mollusks, the genetic aspects associated with their defense mechanisms, pathogen virulence factors, and symbiotic and pathogenic microbiota, highlighting genera Vibrio, Aspergillus, and Escherichia coli pathogenic pathotypes. The bacterial and fungal microbiota in mollusks have been studied in several areas of knowledge and have given rise to research that can support the proper management of mollusks, application in the pharmaceutical industry, and implementation of measures in public health.

“…Cytotoxic Necrotizing Factor 1,2 genes are found in enterotoxigenic E. coli (Jarquin et al, 2022). While Bundle-forming Pilus (bfpA) and Enteropathogenic Attachment and Effacement (eaeA) genes are responsible for encoding Enteropathogenic E. coli (EPEC) (Maniha and Noor, 2020). Additionally, Heat-stable and Heat-labile toxin genes are responsible for encoding Enterotoxigenic E. coli and Shiga-like toxin (Stx1) and ( Stx2) genes are responsible for encoding Shiga-like toxin-producing E. coli (STEC) (Huang et al, 2021).…”

Multidrug-resistant Escherichia coli (MDR-E. coli) presents a formidable healthcare challenge, continuously evolving resistance to conventional antibiotics. The aim of this study focuses on assessing the synergistic effect and enhance the effectiveness of traditional antibiotics of mannan extracted from Saccharomyces cerevisiae on MDR-E. coli. Clinical samples (n=150) were collected from several hospitals in Baghdad for both sexes between August and December 2022, including 73 urine, 10 catheter, 13 wound, and 54 stool samples. Among the total collected samples, 112 E. coli isolates were obtained, with 54 derived from urine, 9 from catheter samples, 6 from wound samples, and 43 from stool samples. Antimicrobial susceptibility test (AST) revealed resistance to imipenem (0%) and amikacin (2%), with sensitivity observed for cefotaxime (25%), gentamicin (29%), ceftriaxone (28%), ciprofloxacin (41%), norfloxacin (34%), trimethoprim-sulfamethoxazole (48%), and tetracycline (35%). Mannan purified from S. cerevisiae demonstrated inhibitory effects on E. coli growth, with Minimum Inhibitory Concentrations (MIC) ranging from 100 to 12.5 mg/mL and Minimum Bactericidal Concentrations (MBC) from 25 to 200 mg/mL. Furthermore, mannan exhibited a synergistic effect with conventional antibiotics, pointedly boosting the efficacy of gentamicin (250%), cefotaxime (160%), ceftriaxone (340%), ciprofloxacin (344.4%), norfloxacin (337.5%), and trimethoprim-sulfamethoxazole (237.5%). This research addresses the public health threat posed by MDR-E. coli, highlighting the potential of S. cerevisiae mannan as a promising solution for inhibiting E. coli and improving antibiotic efficacy.
