Resistant Escherichia coli isolated from wild mammals from two rescue and rehabilitation centers in Costa Rica: characterization and public health relevance. Sci Rep 2024; 14:8039. [PMID: 38580725 PMCID: PMC10997758 DOI: 10.1038/s41598-024-57812-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2024] [Accepted: 03/21/2024] [Indexed: 04/07/2024] Open
Abstract
This study aimed to characterize the antimicrobial resistance (AMR) and virulence profiles of 67 Escherichia coli isolates obtained from faecal samples of 77 wild mammals from 19 different species, admitted in two rescue and rehabilitation centers in Costa Rica. It was possible to classify 48% (n = 32) of the isolates as multidrug-resistant, and while the highest resistance levels were found towards commonly prescribed antimicrobials, resistance to fluoroquinolones and third generation cephalosporins were also observed. Isolates obtained from samples of rehabilitated animals or animals treated with antibiotics were found to have significantly higher AMR levels, with the former also having a significant association with a multidrug-resistance profile. Additionally, the isolates displayed the capacity to produce α-haemolysins (n = 64, 96%), biofilms (n = 51, 76%) and protease (n = 21, 31%). Our results showed that AMR might be a widespread phenomenon within Costa Rican wildlife and that both free-ranging and rehabilitated wild mammals are potential carriers of bacteria with important resistance and virulence profiles. These results highlight the need to study potential sources of resistance determinants to wildlife, and to determine if wild animals can disseminate resistant bacteria in the environment, potentially posing a significant threat to public health and hindering the implementation of a "One Health" approach.

Abstract
Antimicrobial resistance (AMR) - the ability of microorganisms to adapt and survive under diverse chemical selection pressures - is influenced by complex interactions between humans, companion and food-producing animals, wildlife, insects and the environment. To understand and manage the threat posed to health (human, animal, plant and environmental) and security (food and water security and biosecurity), a multifaceted 'One Health' approach to AMR surveillance is required. Genomic technologies have enabled monitoring of the mobilization, persistence and abundance of AMR genes and mutations within and between microbial populations. Their adoption has also allowed source-tracing of AMR pathogens and modelling of AMR evolution and transmission. Here, we highlight recent advances in genomic AMR surveillance and the relative strengths of different technologies for AMR surveillance and research. We showcase recent insights derived from One Health genomic surveillance and consider the challenges to broader adoption both in developed and in lower- and middle-income countries.

Extended-spectrum beta-lactamase in Escherichia coli isolated from humans, animals, and environments in Bangladesh: A One Health perspective systematic review and meta-analysis. One Health 2023; 16:100526. [PMID: 37363210 PMCID: PMC10288049 DOI: 10.1016/j.onehlt.2023.100526] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Revised: 03/07/2023] [Accepted: 03/07/2023] [Indexed: 03/12/2023] Open
Abstract
Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli has been linked to both life-threatening hospital- and community-acquired infections across the globe. Here, we conducted a systematic review and meta-analysis to evaluate the prevalence of ESBL in E. coli isolated from humans, animals, and environments in Bangladesh. Following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines, the current systematic review and meta-analysis was taken into account for studies published between 2010 and 2021 in peer-reviewed journals. The meta-analysis was performed on "R" version 4.2.2. A total of 36 studies were included in this systematic review and meta-analysis; among them, 22 were human, seven were animal, four were environmental, and three were multidisciplinary studies. The meta-analysis revealed that the pooled prevalence of ESBL-producing E. coli in Bangladesh was 21% (95% CI: 15%-27%). On the sample basis, the pooled prevalence of ESBL-producing E. coli in humans, animals, and environments was 17% (95% CI: 11%-23%), 22% (95% CI: 9%-34%), and 39% (95% CI: 16%-62%), respectively. All the pooled prevalence of ESBL-producing E. coli showed substantial heterogeneity (I2 > 75%; p < 0.05) among the selected studies. This systematic review reported 13 different types of resistance genes encoding ESBL, such as blaTEM-1 (37.5%), blaCMY (34.6%), blaCTX-M-1 (20.7%), blaCTX-M-15 (16.1%), blaTEM (12.3%), blaCTX-M and blaOXA (9.6%), blaOXA-1 (5.8%), blaampC (3.9%), blaSHV (3.8%), blaCMY-2 (2.3%), blaCTX-M-14 (1.3%), and blaCTX-M-9 (0.3%). Moreover, 39 types of epidemiologically important clones (including ST10 and ST131) were detected in ESBL-producing E. coli isolated from humans, animals, and environments in Bangladesh. To the best of our knowledge, this is the first systematic review and meta-analysis of integrated studies on ESBL-producing E. coli using the One Health approach in Bangladesh. The high prevalence of ESBL-producing E. coli, their resistance genes, and epidemiologically important clones in humans, animals, and environments highlights the importance of implementing comprehensive antimicrobial resistance (AMR) surveillance under a One Health perspective to mitigate the AMR consequences in Bangladesh.

Abstract
Antibiotic stewardship (AS) programs have become a priority for health authorities to reduce the number of infections by super-resistant microorganisms. The need for these initiatives to minimize the inadequate use of antimicrobials is essential, and the election of the antibiotic in the emergency department usually impacts the choice of treatment if the patients need hospital admission, becoming an opportunity for antibiotic stewardship. In the pediatric population, broad-spectrum antibiotics are more likely to be overprescribed without any evidence-based management, and most of the publications have focused on the prescription of antibiotics in ambulatory settings. Antibiotic stewardship efforts in pediatric emergency departments in Latin American settings are limited. The lack of literature on AS programs in the pediatric emergency departments in Latin America (LA) limits the information available. The aim of this review was to give a regional perspective on how pediatric emergency departments in LA are working towards antimicrobial stewardship.

Abstract
Salmonella is an important enteric pathogen that poses a threat to human and livestock animal health, with emerging multidrug resistance (MDR) a major public health issue globally. We investigated the prevalence of Salmonella in healthy and diseased pigs from Thai pig farms and determined their phenotypic and genotypic antimicrobial resistance profiles. A total of 150 fecal samples were collected from pigs housed in pens from four separate pig farms in southern Thailand and tested for the presence of Salmonella. Confirmed Salmonella isolates were tested for their susceptibility to 11 antimicrobials, and PCR used to detect known antimicrobial resistance genes (ARGs). Salmonella isolates were cultured from 69% (103/150) of all fecal samples, with higher prevalence in disease pigs (12/15; 80%), compared with healthy pigs (91/135; 67%). Serotype Rissen was the most frequently identified serotype among the Salmonella isolates. Resistance to ampicillin (AMP) (97%), sulfonamide-trimethoprim (SXT) (97%), and tetracycline (TET) (94%) were the most common phenotypes observed. The most common ARGs identified were blaTEM gene (99.%), tetA (87%), sul1 (77%), and dfrA1 (74%), and more than 95% of the Salmonella isolates tested were MDR - based on resistance to three or more antimicrobial classes. The most common antimicrobial resistance pattern exhibited was AMP-TET-SXT (76%), and resistance to colistin (via the mcr-1 gene) was observed in both healthy and diseased pigs. The clonal groups of PFGE analysis in serotype Typhimurium revealed the genetic relationship among Salmonella isolated from healthy and diseased pigs from different pig farms.

Abstract
BACKGROUND Monitoring of antimicrobial resistance (AMR) is of great importance due to the frequency of strains becoming increasingly resistant to antibiotics. This review, using a public health focused approach, which aims to understand and describe the current status of AMR in Morocco in relation to WHO priority pathogens and treatment guidelines. METHODS PubMed, ScienceDirect and Google Scholar Databases and grey literature are searched published articles on antimicrobial drug resistance data for GLASS priority pathogens isolated from Morocco between January 2011 and December 2021. Articles are screened using strict inclusion/exclusion criteria. AMR data is extracted with medians and IQR of resistance rates. RESULTS Forty-nine articles are included in the final analysis. The most reported bacterium is Escherichia coli with median resistance rates of 90.9%, 64.0%, and 56.0%, for amoxicillin, amoxicillin-clavulanic acid, and co-trimoxazole, respectively. Colistin had the lowest median resistance with 0.1%. A median resistance of 63.0% is calculated for amoxicillin-clavulanic acid in Klebsiella pneumonia. Imipenem resistance with a median of 74.5% is reported for Acinetobacter baumannii. AMR data for Streptococcus pneumonie does not exceed 50.0% as a median. CONCLUSIONS Whilst resistance rates are high for most of GLASS pathogens, there are deficient data to draw vigorous conclusions about the current status AMR in Morocco. The recently join to the GLASS system surveillance will begin to address this data gap.

Abstract
Among chronic skin autoinflammatory diseases, Hidradenitis Suppurativa (HS) stands out for its chronicity, highly variable condition, and profound impact on the patients' quality of life. HS is characterized by suppurative skin lesions in diverse body areas, including deep-seated painful nodules, abscesses, draining sinus, and bridged scars, among others, with typical topography. To date, HS is considered a refractory disease and medical treatments aim to reduce the incidence, the infection, and the pain of the lesions. For this purpose, different classes of drugs, including anti-inflammatory molecules, antibiotics and biological drugs are being used. Antimicrobial peptides (AMPs), also called defense peptides, emerge as a new class of therapeutic compounds, with broad-spectrum antimicrobial action, in addition to reports on their anti-inflammatory, healing, and immunomodulating activity. Such peptides are present in prokaryotes and eukaryotes, as part of the innate eukaryotic immune system. It has been proposed that a deregulation in the expression of AMPs in human epithelial tissues of HS patients may be associated with the etiology of this skin disease. In this scenario, plant AMPs stand out for their richness, diversity of types, and broad antimicrobial effects, with potential application for topical systemic use in patients affected by HS.

Abstract
Background The black spiny‐tailed iguana (Ctenosaura similis) is an endemic animal in Mesoamerica, whose meat is consumed by the local population. Objectives Because the black spiny‐tailed iguana may be potential reservoirs of pathogens, this study aimed to isolate and characterise Salmonella spp. in their meat commercialised in markets of the city of León, Nicaragua. Methods Thirteen specimens were analysed for the isolation of Salmonella spp., as well as their antimicrobial resistance patterns, including the presence of genes encoding extended‐spectrum β‐lactamases. Results Salmonella spp. isolates were found in eight out of 13 samples, with S. enterica serovar Enteritidis being found in six out of eight samples. Moreover, eight Salmonella spp. isolates were resistant to amoxicillin plus clavulanic acid and cephalexin, but sensitive to other tested antibiotics. The blaSHV gene was detected in seven out of eight Salmonella spp. isolates, followed by the blaTEM (two out of eight) and blaCXT‐M (one out of eight) genes. Conclusions These findings represent an important contribution to the implementation of appropriate strategies to prevent foodborne diseases. A high frequency of Salmonella was observed in Ctenosura similis meat in markets of the city of León. Salmonella enterica serovar Enteritidis was the most frequent. Moreover, high antimicrobial resistance to amoxicillin/clavulanic acid and cephalexin was observed coinciding with the presence of the blaSHV gene.
