In addition, close human-animal interactions and unregulated antibiotic use in livestock facilitate the spread of resistant bacteria. We use metagenomic sequence data and multivariate models to assess how animal exposure and WASH conditions affect the gut resistome and microbiome in 53 pregnant women and 84 children in Ecuador. Here we show improving WASH infrastructure and managing animal exposure may be important in reducing AMR but could also reduce taxonomic diversity in the gut. Escherichia coli , Klebsiella pneumoniae , and clinically relevant antimicrobial resistance genes (ARGs) are detected across all age groups, but the highest abundance is found in children compared to mothers. In mothers, higher animal exposure trends towards a higher number of unique ARGs compared to low animal exposure and is significantly associated with greater taxonomic diversity. In addition, mothers with sewer systems or septic tanks and piped drinking water have fewer unique ARGs compared to those without, and mothers with longer duration of drinking water access have lower total ARG abundance. In contrast, few associations are observed in children, likely due to the dynamic nature of the gut microbiome during early childhood.
Antimicrobial Resistance Gene Profiles in Integron-Positive and Integron-Negative Third-Generation Cephalosporin-Resistant E. coli from Human and Animal Sources Tin Ho, Liseth Salinas, Gabriel Trueba, Heather K. Amato, Nikolina Walas, Mihir Pandya, Timothy Johnson, Jay Graham Antibiotics, 2026 Background/Objectives: Integrons are genetic platforms that allow bacteria to acquire antimicrobial resistance (AMR) genes, making them a focal point for many AMR studies and surveillance programs. This study investigated how the prevalence of integrons (intI and attI genes) in third-generation cephalosporin-resistant E. coli (3GCR-Ec) varied across three different sources (i.e., healthy children, domestic animals and urinary tract infections). The study aimed to determine how different classes of AMR genes vary among 3GCR-Ec with integrons present versus those where integrons are absent. Methods: We analyzed 3GCR-Ec isolates collected from semirural parishes of Eastern Quito, Ecuador, that included: (1) 3GCR-Ec from healthy children (n = 946), (2) 3GCR-Ec from domestic animal species (n = 673), and 3GCR-Ec from patients with urinary tract infections (UTIs) (n = 138). Genomic analyses were performed for all 1757 sequences to determine how the presence and absence of integrons was associated with AMR gene carriage. Results: Among the total sequences of 3GCR-Ec evaluated across all datasets, nearly one-third (31%) were integron-negative. 3GCR-Ec from UTI patients, however, had a higher percentage containing integrons (79%). Across all sets of 3GCR-EC, integron-positive isolates carried an average of 10.3 (±3.0 SD) AMR genes versus 4.8 (±2.5 SD) AMR genes in integron-negative isolates. This study found that between 21% to 33% of 3GCR-Ec across the three different sources lacked integrons but maintained the ability to carry diverse classes of AMR genes, including beta-lactams, aminoglycosides, tetracyclines, and multidrug resistance mechanisms (e.g., general-purpose efflux pumps). Conclusions: While integrons were associated with greater AMR genes on average, the study highlights that solely relying on integrons for tracking drug-resistant bacteria misses a substantive portion of AMR that is present in integron-negative strains.
Extreme Rainfall Modifies the Association between Piped Water Intermittency and Water Quality in Low-Resource Settings Andrea Sosa-Moreno, Gwenyth O. Lee, Rebecca S. Kann, Josefina Coloma, Gabriel Trueba, William Cevallos, Zhenke Wu, Dimitrios Gounaridis, Karen Levy, Joseph N. S. Eisenberg ACS Es and T Water, 2026 Intermittent water supply (IWS), where piped water is not continuously available, can compromise water security and quality. Extreme rainfall may exacerbate these risks by enabling microbial contaminants to enter distribution systems. We assessed the association between household piped water intermittency and Escherichia coli concentrations in drinking water samples sourced from piped systems ( n = 1098) and whether extreme rainfall events (>90th percentile) modified this relationship. Participants included 234 households from six Ecuadorian communities in the ECoMiD birth cohort. We measured intermittency as days/week, hours/day, and hours/week without water supply. Households in IWS communities had significantly more contaminated water samples than those in the city, which had a nearly continuous water supply (CWS) (OR: 10.4 [95% CI: 5.9–18.4]). Extreme rainfall modified the association between IWS and water contamination ( p for interaction = 0.014): each additional day without water was associated with 42% higher odds of contamination when an extreme rainfall event occurred within 4 days prior to sampling (1.42 [1.09–1.84]). Effect modification was also observed for rainfall lag windows of 3–7 days but not for other intermittency definitions. These findings suggest that more frequent water service interruptions per week may exacerbate household vulnerability to extreme weather events, reinforcing the need for a resilient, well-maintained water infrastructure.
Child exposure to animal feces and zoonotic pathogens in northwest Ecuador: A mixed-methods study Viviana Albán, April M. Ballard, Kelsey J. Jesser, Gwenyth O. Lee, Joseph N.S. Eisenberg, Daniel Garzon-Chavez, Gabriel Trueba, Bethany A. Caruso, Karen Levy Plos Neglected Tropical Diseases, 2026 In low- and middle-income countries (LMICs), close cohabitation with animals and limited access to water, sanitation, and hygiene (WASH) infrastructure increase the risk of zoonotic enteric pathogen transmission to young children. This mixed-methods study combined (A) microbiological analysis of 120 animal fecal samples, and (B) go-along, semi-structured interviews with 35 mothers of children under two years across urban (n = 10), intermediate (n = 15), and rural (n = 10) communities in Ecuador to investigate: (Q1) What zoonotic enteric pathogens are present in animal feces and at what concentrations? (Q2) How are children exposed to animals and their feces? and (Q3) Which animals may serve as key sources of child exposure? Microbiological analysis revealed high prevalence and concentrations of zoonotic pathogens, most commonly E. coli aEPEC (57%), Salmonella sp. (36%), and E. coli STEC (25%), with frequent co-infections (33%) and concentrations (4.97-9.29 log10 gc/g) often exceeding infectious dose thresholds. Qualitative findings showed risks from free-roaming animals, poor feces management, and frequent child–animal contact, often indirectly through caregivers and siblings. Triangulation identified chickens and dogs as the most likely potential exposure sources due to their behaviors, proximity to children, and pathogen carriage. These findings highlight the need for targeted interventions to limit animal roaming, improve animal feces management, and increase caregiver awareness, while underscoring how mixed-methods approaches can help identify context-specific exposure pathways that should be considered when designing interventions.
Fitness costs and persistence of plasmid-mediated cephalosporin resistance in Escherichia coli: an integrative review Lázaro López, Pamela Cangui, Denyss Guilcazo, Antonio Machado, Zachary D. Blount, Gabriel Trueba Frontiers in Microbiology, 2026 The global spread of resistance to third-generation cephalosporins (TGCs) in Escherichia coli limits therapeutic options and poses major challenges for human, animal, and environmental health. The spread of resistance genes, including those for extended-spectrum β-lactamases (ESBLs), AmpC-type β-lactamases, and carbapenemases, has been facilitated by horizontal gene transfer (HGT), often via conjugative plasmids. This plasmid-mediated mobilization has enabled rapid adaptation to front-line antibiotics across diverse bacterial populations and ecological niches. Here, we bring together an integrative synthesis of molecular mechanisms, genetic vehicles, and ecological dynamics of cephalosporin resistance in E. coli , alongside a PRISMA-guided quantitative synthesis of 40 studies that provide data on the fitness consequences of resistance plasmids. We have analyzed a total of 154 experimental observations to identify patterns related to plasmid host background, resistance gene family, and fitness-assay framework. Because multiple observations were frequently contributed by the same study, we accounted for hierarchical structure using mixed-effects models with Study_ID as a random intercept and evaluated key patterns in the full dataset and stratified by assay type (growth curves vs. head-to-head competition assays). Moreover, we found that fitness estimates were sensitive to assay type. For instance, head-to-head competition experiments captured a broader range of deviations from neutrality than growth curve assays, although the apparent difference in mean standardized fitness between assay types was attenuated after accounting for study-level clustering. Across the curated dataset, host-associated and resistance gene-family-associated signals were method-dependent: both were evident overall and in head-to-head competition assays, but were not retained in growth-curve-only subsets. Our analysis supports a context-dependent interpretation in which plasmid-host compatibility, resistance-gene context, ecological setting, and the measurement framework jointly shape the observed fitness consequences and dissemination potential of resistance plasmids across environments.
Microbial source tracking of human and animal fecal contamination in Ecuadorian households Kelsey J. Jesser, Viviana Alban, Aldo E. Lobos, Javier Gallard-Góngora, Gabriel Trueba, Gwenyth O. Lee, Joseph N. S. Eisenberg, Valerie J. Harwood, Karen Levy Applied and Environmental Microbiology, 2026 Exposures to both human and animal feces pose human health risks, particularly for young children in low- and middle-income country (LMIC) settings where domestic animals are common, water and sanitation infrastructure is often limited, and enteropathogen transmission is high. Microbial source tracking (MST) markers specific to feces from humans and particular animal types can be used to identify the provenance of microbial contamination, yet most MST studies explore few household environmental sample types, limiting the understanding of how marker utility varies by matrix. We validated qPCR assays for six MST markers and quantified their prevalence in 585 samples from 59 households spanning an urban–rural gradient in northwestern Ecuador. We used GenBac3 to test for general fecal contamination and HF183, Rum2Bac, Pig2Bac, DG37, and GFD to test for human, ruminant, swine, dog, and avian contamination, respectively. Approximately 10 sample types were collected per household, including the following: rinses of child and adult hands, swabs of floors and surfaces, soil, domestic and drinking water, and food. GenBac3 and HF183 were detected in 77.82% and 15.36% of samples, respectively. Animal-associated markers were detected less frequently, in 0.5%–4.1% of samples. However, when present, animal marker concentrations were comparable to HF183. Host-associated markers were most often detected in adult and child hand rinse and floor samples, and GenBac3 concentrations were highest in hand rinse samples. HF183 detection on adult caregiver hands was associated with increased odds of HF183 detection on children’s hands and floors. Together, these findings identify hands and floors as reservoirs of fecal contamination and highlight the need for integrated interventions that address both human and animal sources to address household exposures to reduce exposures to enteric pathogens. IMPORTANCE Understanding the sources and pathways of detectable household environmental fecal contamination is critical for identifying how exposures occur and for developing targeted interventions to reduce risk of enteric infection. By linking contamination on caregiver hands to that on children’s hands and floors, we highlight a likely route for pathogen transfer in the home. The inclusion of multiple host-associated markers across a wide range of sample types reveals patterns that narrower studies may miss, offering new insights into the complex ecology of fecal contamination. These findings can inform sampling strategies, guide risk assessments, and support the design of interventions aimed at reducing child exposure to enteric pathogens in similar high-risk settings.
Socioecological drivers of water, sanitation, and hygiene (WASH) choices: A qualitative analysis of maternal perspectives in northwest Ecuador Molly K. Miller-Petrie, Gwenyth O. Lee, Marie L. Spiker, Adriana Lupero, Mauricio Ayovi, William Cevallos, Gabriel Trueba, Joseph N. S. Eisenberg, Karen Levy Plos Water, 2026 Household-level water, sanitation, and hygiene (WASH) interventions do not always achieve sustainable uptake. Research that considers WASH within a socioecological framework, where multi-level factors are interconnected in influencing choices, can inform more effective interventions. To understand WASH preferences and priorities under different socioeconomic and community contexts, we conducted in-depth interviews and freelisting activities with 33 mothers of children under age two participating in the ECoMiD study in northwest Ecuador. Data were inductively coded and connected thematically to the socioecological framework. Select survey data from ECoMiD were analyzed to provide additional context. Maternal WASH choices are driven by factors at each level of the framework. Climatic: seasonal flooding decreases the appeal of WASH investments like cisterns, and household wealth facilitates access in times of climatic stress. Geographic: benefits of WASH access via proximity to piped systems are complicated by quality and consistency concerns, while access from proximity to rivers is complicated by labor requirements. Community: local infrastructure dictates individual options for accessing WASH, and local conditions are dictated by national sociopolitical context and policy decisions. Household: consistent, quality piped water for drinking and chores is the most common maternal WASH preference. WASH choices respond to financial and labor constraints. Individual: mothers value time-savings associated with WASH technologies and access. Maternal decision making operates at the terminus of a chain of broader and interconnected socioecological conditions. The burden of obtaining WASH access is greatest for the poorest households with the least community infrastructure, compounded by seasonal conditions. This contextually grounded study draws attention to how socio-spatial, economic, and environmental constraints interact in the Ecuadorian context to shape lived experience. Improving community-level WASH and taking a multisectoral approach to health interventions would better address barriers to WASH access, and support mothers in making WASH-related choices that can ultimately improve child health and wellbeing.
Investigating the zoonotic origins of ESBL-producing E. coli in community-acquired urinary tract infections in Ecuador Yashan Wang, Daniel E. Park, Maliha Aziz, Liseth Salinas, Edward Sung, Søren Hallstrøm, Cindy M. Liu, Marc Stegger, Zhenke Wu, Gabriel Trueba, Joseph N. S. Eisenberg, Jay P. Graham, Lance B. Price Microbiology Spectrum, 2026 Extended-spectrum β-lactamase-producing Escherichia coli (ESBL-producing E. coli ) pose a growing global health threat. Although Latin America has been identified as a global hotspot of antimicrobial resistance, the zoonotic contribution to drug-resistant infections in the region remains poorly defined. We analyzed 137 clinical ESBL-producing E. coli isolates from urinary tract infections (UTIs) in Quito, Ecuador, applying a Bayesian latent class model informed by host-associated mobile genetic elements to estimate the fraction of infections attributable to food-animal sources. We estimated that 25.5% (35/137) of UTI isolates were putative zoonotic cases. This proportion rose to 42.5% after excluding ST131- H 30, a human-associated pandemic lineage. Putative zoonotic isolates were enriched for animal-associated β-lactamase genes (e.g., bla TEM-1B , bla CTX-M-65 ), lacked human-associated markers such as bla OXA-1 , and exhibited diverse antimicrobial resistance gene profiles resembling those observed among food-animal isolates. These isolates were also enriched for ColV-associated virulence genes typically linked to avian pathogenic E. coli . Putative zoonotic strains contributed substantially to third-generation cephalosporin-resistant UTIs in Quito, Ecuador, challenging assumptions derived from high-income settings that such infections are driven predominantly by human-to-human transmission. These findings highlight the importance of integrated One Health surveillance and mitigation, particularly in low- and middle-income countries where gaps in water, sanitation, and hygiene (WASH) may interact with antimicrobial use in food production to amplify antimicrobial resistance transmission. IMPORTANCE ESBL-producing E. coli have rapidly emerged as a major global antimicrobial resistance threat. In Latin America, cephalosporins are commonly used in food-animal production, fueling the emergence of ESBL-producing E. coli . In low- and middle-income countries, excessive antimicrobial use driven by poorly regulated over-the-counter sales, combined with inadequate water, sanitation, and hygiene (WASH) infrastructure, can facilitate antimicrobial-resistant pathogen transmission from food animals to humans. Using a novel statistical-genomic approach, we found that over one in four cephalosporin-resistant UTIs in Quito, Ecuador, may be caused by E. coli strains originating from food animals. Our findings highlight the public health risks associated with antimicrobial use in food-animal production and the role of environmental and infrastructure-related vulnerabilities. As global demand for animal protein continues rising in middle-income countries, controlling zoonotic antimicrobial resistance transmission becomes increasingly urgent for protecting human health through integrated One Health strategies.
Global health at crossroads: uniting together to overcome challenges, restore trust and advance priorities for a sustainable future Massimo Sartelli, Elías Mossialos, Federico Coccolini, Ib Jammer, Francesco M. Labricciosa, et al. World Journal of Emergency Surgery, 2025 The world is currently facing an unprecedented convergence of crises that threaten the core pillars of public health, scientific integrity, and social stability. These challenges are profoundly interconnected and have the potential to exacerbate global inequalities, jeopardize health security, and undermine the progress achieved through decades of international collaboration. Our viewpoint declaration, developed by 366 healthcare workers and scientists from 119 countries across six continents, highlights the urgent need for global solidarity and collective action to address these interconnected global health challenges. As healthcare workers and scientists, we must prioritize the protection of scientific integrity, combat political interference, and restore public trust in the scientific process. This will require a commitment to transparency, ethical responsibility, and evidence-based decision-making that can stand strong in the face of political and social adversity. The COVID-19 pandemic has underscored the critical importance of resilient healthcare systems, emphasizing that preparedness, capacity building and coherent leadership and coordination are essential for future global health crises. In addition, our call for a One Health approach, acknowledging the intricate relationship between human, animal, and environmental health, has never been more pressing, especially as zoonotic diseases and antimicrobial resistance spread across borders. As we confront ongoing wars, environmental destruction, and global persistent health inequalities, it is only through unity, solidarity, collaboration, and innovation that we hope to build a healthier, more equitable world. Together, we must ensure that science and medicine remain a force for good, capable of addressing both the immediate and long-term needs and challenges facing our shared future.
