Sources Of Contamination

Infections by Extended-Spectrum Beta-Lactamase producing Escherichia coli (ESBL-Ec) are on the increase in Ghana, but the level of environmental contamination with this organism, which may contribute to growing Antimicrobial Resistance (AMR), is unknown. Using the WHO OneHealth Tricycle Protocol, we investigated the contamination of E. coli (Ec) and ESBL-Ec in two rivers in Ghana (Odaw in Accra and Okurudu in Kasoa) that receive effluents from human and animal wastewater hotspots over a 12-month period. Concentrations of Ec, ESBL-Ec and percent ESBL-Ec/Ec were determined per 100 mL sample. Of 96 samples, 94 (98%) were positive for ESBL-Ec. concentrations per 100 mL (MCs100) of ESBL-Ec and %ESBL-Ec from both rivers were 4.2 × 104 (IQR, 3.1 × 103–2.3 × 105) and 2.79 (IQR, 0.96–6.03), respectively. MCs100 were significantly lower in upstream waters: 1.8 × 104 (IQR, 9.0 × 103–3.9 × 104) as compared to downstream waters: 1.9 × 106 (IQR, 3.7 × 105–5.4 × 106). Both human and animal wastewater effluents contributed to the increased contamination downstream. This study revealed high levels of ESBL-Ec in rivers flowing through two cities in Ghana. There is a need to manage the sources of contamination as they may contribute to the acquisition and spread of ESBL-Ec in humans and animals, thereby contributing to AMR.

ABSTRACT From 2002 to 2008, there was a significant increase in extended-spectrum beta-lactamase (ESBL)-positive Escherichia coli isolates in European intra-abdominal infections, from 4.3% in 2002 to 11.8% in 2008 (P < 0.001), but not for ESBL-positive Klebsiella pneumoniae isolates (16.4% to 17.9% [P > 0.05]). Hospital-associated isolates were more common than community-associated isolates, at 14.0% versus 6.5%, respectively, for E. coli (P < 0.001) and 20.9% versus 5.3%, respectively, for K. pneumoniae (P < 0.01). Carbapenems were consistently the most active drugs tested.

Escherichia coliremains as one of the most important bacteria causing infections in pediatrics and producing extended-spectrum beta-lactamases (ESBLs) making them resistant to beta-lactam antibiotics. In this study we aimed to genotype ESBL-producingE. coliisolates from pediatric patients for ESBL genes and determine their association with antimicrobial resistance. One hundred of theE. coliisolates were initially considered ESBL producing based on their MIC results. These isolates were then tested by polymerase chain reaction (PCR) for the presence or absence ofCTX,TEM,SHV,GES, andVEBbeta-lactamase genes. About 30.5% of isolatedE. coliwas ESBL-producing strain. TheTEMgene was the most prevalent (49%) followed bySHV(44%),CTX(28%),VEB(8%), andGES(0%) genes. The ESBL-producingE. coliisolates were susceptible to carbapenems (66%) and amikacin (58%) and showed high resistance to cefixime (99%), colistin (82%), and ciprofloxacin (76%). In conclusion, carbapenems were the most effective antibiotics against ESBl-producingE. coliin urinary tract infection in North of Iran. The most prevalent gene is the TEM-type, but the other resistant genes and their antimicrobial resistance are on the rise.

Aims: This study investigated the antimicrobial resistance profile and extended spectrum beta-lactamase resistance genes of Escherichia coli isolated from droppings of from selected poultry farms in Nasarawa, Nigeria. Study Design: Investigative Place and Duration of Study: Department of Microbiology, Nasarawa State University, Keffi, between November 2019 and February 2020. Methodology: A total of 90 samples from poultry droppings were collected from selected farms. Escherichia coli was isolated from the samples using standard cultural and microbiological methods. Antibiotic susceptibility testing and minimum inhibitory concentrations were evaluated as described by the Clinical and Laboratory Standards Institute (CLSI). The detection of extended-spectrum beta-lactamase (ESBL) production in E. coli isolates was carried out using double disc synergy test.  In addition, molecular detection of ESBL genes was carried out using Polymerase Chain Reaction (PCR) method. Results: The prevalence of E. coli was 100%. Antibiotic resistances of E. coli were recorded as follows: streptomycin (S: 94.4%), sulphamethoxazole / trimethoprim (SXT: 90.0%), ampicillin (AMP: 88.9%), gentamicin (CN: 68.9%), amoxicillin/clavulanic acid (AMC: 55.6%), ciprofloxacin (CIP: 41.1%), cefoxitin (FOX: 35.6%), ceftazidime (CAZ: 34.4%), cefotaxime (CTX: 22.2%), and imipenems (IPM: 17.8%). The most common antibiotic resistant resistance phenotype was AMP-CTX-CAZ-CIP-CN (11.1%). Multiple antibiotic resistance (MAR) was observed in 97.7% (88/90) of the isolates, with the common MAR index being 0.5 (33.3%). Twenty five of the thirty beta-lactam resistant isolates (83.3%) were confirmed ESBL producers. The 25 ESBL positive isolates carried bla genes as follows: blaTEM (11/25, 44.0%) and blaCTX-M (18/25, 72.0%). blaSHV was not found in any isolate. Conclusion: E. coli isolated from the droppings of selected poultry farms in Nasarawa were less resistant to imipenem, cefotaxime, ceftazidime and cefoxitin in the study location. This implies that the antibiotics are useful in the treatment of infection caused by E. coli. Also, ESBL-positive E. coli isolates harbored ESBL genes, with blaCTX-M as the most common.

Antimicrobial resistance has become a major global public health threat. Extended-spectrum beta-lactamase (ESBL) producing E. coli appears as an emergence cause of treatment failure and increase mortality due to limited available effective antimicrobial agents. This study was conducted to determine the occurrence and antimicrobial resistance of ESBL producing E. coli in broilers, farm workers and environment in broiler farms in Chiang Mai-Lamphun, Thailand. The prevalence of ESBL producing E. coli in the broiler farms was 60.4% (29/48). The prevalence of ESBL producing E. coli from boot swabs, farm worker’s rectal swabs, feed and water samples were 43.8%, 55.7%, 12.5% and 2.1%, respectively. All isolates showed susceptible to imipenem and, in contrast, resistant to ampicillin. The results demonstrated high antimicrobial resistant rate to streptomycin (94.3%), gentamicin (86.8%), tetracycline (77.4%), chloramphenicol (66.0%), nalidixic acid (58.5%), and sulfamethoxazole/trimethoprim (56.6%). High percentage (96.2%) of isolates was classified as multidrug resistance (MDR). Thirty-five antimicrobial resistance profiles were identified with AMP-GEN-SXT-NAL-TET-CHL-STR, AMP-GEN-SXT-TET-CHL-STR (14.3%) as the 2 most prevalent profiles. The common resistance profiles between farm workers and broilers was demonstrated. These findings are suggestive for possible transmission between poultry and humans in broiler farms, most likely via close contact. Antimicrobial usage should be strictly controlled together with increase awareness on hygiene practices in broiler farms.

Extended Spectrum Beta Lactamase (ESBL)-producing Escherichia coli (E. coli) infections are a global health challenge resulting from human contact with infected animals and contaminated farm environments. This study aims to identify antimicrobial resistance patterns of ESBL-producing E. coli isolated from dairy farms in the Sleman District of Yogyakarta Province, Indonesia. Ninety-three dairy farms with a history of antibiotic use in the previous 6 months were identified. Samples were collected from 6 different sources (feces, milk, wastewater, animal drinking water, feed and rinses of workers’ hands) on each farm during August through November 2020. These samples were cultured with conventional microbiological methods for the isolation of ESBL-producing E. coli. ESBL-producing E. coli was identified in one or more of the sources in 54% (50/93) of the dairy farms sampled. Fecal samples were the most commonly positive (25%) while wastewater, animal drinking water feed, milk and hand rinses were positive at 16%, 10%, 5%, 4% and 3% respectively. Colonies from each positive sample were screened for antibiotic susceptibility test using the Vitek-2 system. Resistance to trimethoprim/sulfamethoxazole, tetracycline and gentamicin were found in 74%, 63% and 48% of the isolates, respectively. Multidrug resistant (MDR) was identified in 50% (63/127) of the isolates. In conclusion, ESBL-producing E. coli appears widespread in dairy farms using antibiotics and antimicrobial resistance among these bacteria is common in this study area. Further study of the risk of human transmission from contaminated cattle and their environments could benefit the national antimicrobial resistance strategic plans.

ABSTRACTWe assessedEscherichia coliST131 and its H30 and H30-Rx subclones for virulence genes, antimicrobial resistance, and extended-spectrum beta-lactamase (ESBL) type. Although both subclones were associated with ESBL production, H30-Rx isolates had higher resistance scores and were associated specifically with CTX-M-15. Three virulence genes (iha,sat, andiutA) were more prevalent among H30 than non-H30 ST131 isolates. Thus, the H30 and H30-Rx subclones are more antimicrobial resistant and have virulence profiles that are distinct from those of non-H30 ST131 isolates.

During winter, a large number of rooks gather and defecate at the park of a university clinic. We investigated the prevalence of extended-spectrum beta-lactamase (ESBL)–producing Escherichia coli in these birds and compared recovered isolates with contemporary human isolates. In 2016, fecal samples were collected from 112 trap-captured rooks and investigated for presence of ESBL producers using eosin methylene blue agar supplemented by 2 mg/L cefotaxime; 2,455 contemporary human fecal samples of patients of the clinics sent for routine culturing were tested similarly. In addition, 42 ESBL-producing E. coli isolates collected during the same period from inpatients were also studied. ESBL genes were sought for by PCR and were characterized by sequencing; E. coli ST131 clones were identified. Epidemiological relatedness was determined by pulsed-field gel electrophoresis and confirmed using whole genome sequencing in selected cases. Thirty-seven (33%) of sampled rooks and 42 (1.7%) of human stools yielded ESBL-producing E coli. Dominant genes were blaCTX–M–55 and blaCTX–M–27 in corvid, blaCTX–M–15 and blaCTX–M–27 in human isolates. ST162 was common among rooks. Two rook-derived E. coli belonged to ST131 C1-M27, which was also predominant (10/42) among human fecal and (15/42) human clinical isolates. Another potential link between rooks and humans was a single ST744 rook isolate grouped with one human fecal and three clinical isolates. Despite possible contact, genotypes shared between rooks and humans were rare. Thus, rooks are important as long-distance vectors and reservoirs of ESBL-producing E. coli rather than direct sources of infections to humans in our setting.
