Опубликована: Май 27, 2022

The aim of the present study was to investigate presence, pathogenic potential and antimicrobial susceptibility profile Escherichia coli isolated from raw milk cheese, traditionally produced by farmers marketed directly consumer in Banat region, Romania. A total 81.1% (43/53) processed samples expressed positive results for E. coli, with a distribution 83.8% (31/37), 75.0% (12/16) cow- sheep-milk-origin assortments, respectively. Overall, 69.8% (30/43) specimens had contamination level ≤10 CFU/g. Molecular tests showed that, number isolates, 9.3% (4/43) harbored stx2, 2.3% (1/43), stx1 virulence genes. O157 (including H7) biovariety identified 7% (3/43) Vidas equipment. From 27 antimicrobials tested Vitek2 automated system, isolates displayed resistance enrofloxacin (100%, 15 out isolates), ampicillin (39.5%, 17/43), norfloxacin (28.6%, 8/28), fosfomycin (25%, 7/28), amoxicillin/clavulanic acid (23.3%, 10/43), cefalexin (20%, 3/15), cefalotin (13.3%, 2/15), tetracycline trimethoprim-sulfamethoxazole (9.3%, 4/43), piperacillin-tazobactam (7.1%, 2/28), cefotaxime cefepime ticarcillin/clavulanic (6.7%, 1/15), florfenicol ceftazidime (3.6%, 1/28), ertapenem 1/28). Ten (23.3%) strains were multidrug-resistant. obtained preliminary indicated hygienic-sanitary deficiencies throughout cheese production process, demonstrated that these products can harbor virulent multidrug-resistant strains, which constitute public health risk. However, future investigations, processing higher samples, are still necessary draw comprehensive conclusions.

Опубликована: Янв. 1, 2025

Introduction: Access to safe drinking water is crucial for health and survival, yet many developing countries face significant challenges in this regard. In West Africa, rapid urbanisation has outpaced efforts improve access potable water, compelling households rely on private vendors solutions, particularly through the growing market sachet water. Widely consumed Ghana, become a convenient affordable option, with over 37% of population depending it. However, concerns about its microbial safety persist, as studies indicate that often fails meet necessary standards. This review consolidated existing research contaminants aiming provide representative overview quality Ghana. Method: The systematic followed preferred reporting items reviews meta-analysis (PRISMA) guidelines. A thorough literature search was conducted across multiple databases, including PubMed, Web Science, ScienceDirect, Scopus engine Google Scholar, using relevant terms. Eligible were identified based established criteria, data subsequently extracted analysed. Results: total 28 published from 2003 2024 selected inclusion review. Notably, 96% these reported bacteria 17 different genera, while 11% examined parasites 5 genera. Some (7%) investigated both types contaminants. Overall, 2,276 samples analysed, 1,727 (76%) showing contamination. Escherichia coli most bacteria, Cyclospora cayetanensis Cryptosporidium parvum parasites.

Contamination of Kazakhstan cheeses originating from Escherichia coli and its resistance to antimicrobial drugs

Veterinary World, Год журнала: 2024, Номер unknown, С. 361 - 370

Опубликована: Фев. 1, 2024

Background and Aim: Escherichia coli, a commensal intestine bacterium of vertebrates, is widely distributed in the environment indicates microbiological quality food products relation to coliforms. In addition, virulent strains, particularly E. coli O157:H7, cause outbreaks toxic infections caused by consuming dairy products. Because safety studies regarding have not been conducted Central Asia, this research aimed study characteristics contamination, genotypic properties, resistance antimicrobial agents strains that contaminate various types commercialized cheeses originating from Kazakhstan. Materials Methods: retail outlets, 207 samples three cheese produced 22 industrial eight small enterprises central, eastern, southern, northern regions Kazakhstan were selected 2020–2023. contamination was examined using standard microbiological, mass spectrometric, molecular genetic methods. The discodiffuse European Committee on Antimicrobial Susceptibility Testing method used test identified isolates (65/207; 31.4%) 20 antibacterial drugs. Shiga toxin-producing (VT1 VT2) O157:H7 (eae) genes investigated all multiplex polymerase chain reaction. Results: An average 31.4% commercial Kazakhstani found be contaminated with almost geographical Kazakhstan, regardless productivity enterprises. Soft farms (80% samples) packaged at site (100%) most coli. index (colony-forming unit/g) unsatisfactory unsuitable 6.2% such samples. For first time enteropathogenic strain detected 0.5% resistant 65% drugs contained β-lactams, sulfonamides, quinolones groups. At same time, 25% multi-resistant or more agents. Conclusion: high level multi-antibiotic including pathogenic pathogens, poses risk public health highlights need for further monitoring control coliform enteropathogens Keywords: antibiotic resistance, cheese, microbial contamination.

Abstract Background Camels harbouring multidrug-resistant Gram-negative bacteria are capable of transmitting various microorganisms to humans. This study aimed determine the distribution anti-microbial resistance among Escherichia coli ( E. ) isolated from feces apparently healthy camels in Egyptian abattoirs. Additionally, we sought characterize Shiga toxin-producing (STEC) strains, assess their virulence potential, and investigate possibility spreading carbapenem- colistin-resistant . Methods 121 fecal swaps were collected different abattoirs Egypt. Isolation identification performed using conventional culture techniques biochemical identification. All isolates obtained examined samples underwent genotyping through polymerase chain reaction (PCR) toxin-encoding genes Stx1 Stx2 ), carbapenemase-encoding bla KPC , OXA−48 NDM VIM mcr for mcr-1 mcr-5 Result Bacteriological examination revealed 75 isolates. PCR results that one strain (1.3%) tested positive five (6.6%) Among total strains overall prevalence carbapenemase-producing was 27, with 7 carrying OXA48 14 6 Notably, no but a high rate detected. mcr-1, mcr-2, mcr-3, mcr-4 detected 3, 2, 21, 3 respectively. Conclusion The indicate Egypt may be primary source (AMR) which could potentially transmitted directly humans or food chain.

Antibiotics, Год журнала: 2022, Номер 11(12), С. 1688 - 1688

Опубликована: Ноя. 23, 2022

The occurrence of waterborne antimicrobial-resistant (AMR) bacteria in areas high-density oyster cultivation is an ongoing environmental and public health threat given the popularity shellfish consumption, water-related human recreation throughout coastal Thailand, geographical expansion Thailand’s industry. This study characterized association phenotypic genotypic AMR, including extended-spectrum β-lactamase (ESBL) production, virulence genes isolated from Escherichia coli (E. coli) (n = 84), Salmonella enterica (S. enterica) subsp. 12), Vibrio parahaemolyticus (V. parahaemolyticus) 249), cholerae cholerae) 39) aquaculture regions. All (100.0%) half V. (51.3%) isolates harbored their unique gene, invA ompW, respectively. majority E. coli, ~25% S. enterica, ~12% cholerae, exhibited AMR to multiple antimicrobials, with 8.9% all water exhibiting multidrug resistance (MDR). Taken together, we recommend that quality surveillance programs include monitoring for bacterial food safety recreational exposure resources.
