“…Anthropogenic drivers of AMR included intensive and non-intensive (small-scale/extensive) animal production systems [ 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 ] and agricultural practices [ 49 , 50 , 52 , 53 , 54 ], such as the use of recycled or composted animal or human manure as fertiliser. Resende et al [ 53 ] showed microbiological evidence of survival of AMR bacteria after biodigestion treatment of cattle manure, which could contaminate soils when applied as fertiliser.…”

“…Poultry was the most common livestock [ 35 , 37 , 39 , 42 , 43 , 44 , 45 , 49 , 50 , 52 ], but fish [ 36 , 48 ], swine [ 38 , 40 , 41 , 42 , 43 , 49 ], and cattle [ 41 , 42 , 46 , 49 , 51 ] were also studied. Only dos Vieira et al [ 47 ] focused on AMR in shrimp production.…”

“…Only dos Vieira et al [ 47 ] focused on AMR in shrimp production. Some studies considered the input of other domestic animal species [ 41 , 42 , 43 , 55 ] such as sheep, ducks, pigeons, horses, dogs, or guinea pigs. Corzo-Ariyama et al [ 54 ] did not specify the type of animal under study; their focus was solely on identifying AMR patterns from bacteria in produce; therefore, they recognised the animal role in the spread of AMR more generally.…”

“…Corzo-Ariyama et al [ 54 ] did not specify the type of animal under study; their focus was solely on identifying AMR patterns from bacteria in produce; therefore, they recognised the animal role in the spread of AMR more generally. By far, animal AMR carriage and/or transfer of AMR determinants or bacteria was the most widely identified animal contribution [ 36 , 37 , 38 , 44 , 46 , 47 , 48 , 50 , 51 , 52 , 53 , 54 ], while several studies mentioned the inadequate or unregulated use of veterinary antimicrobials [ 39 , 40 , 41 , 43 , 47 , 48 , 49 ]. The role of food of animal origin in the spread of AMR bacteria in the human food chain was mentioned as well [ 35 , 36 , 38 , 39 , 42 , 46 , 47 ].…”

Other environmental inputs included: soil [ 37 , 38 , 46 , 49 , 50 , 51 , 52 , 53 , 54 ], farm/bird coop’s environment (which included surfaces, feed, shoe soles, and/or hands of workers) [ 37 , 44 , 45 , 54 ], vectors (flies) [ 40 ], and pond sediments [ 47 ].…”

Antimicrobial resistance (AMR) in rural Latin America is not fully understood. The transmission pathways are partially known since research predominantly focuses on the urban hospital setting. The contribution to AMR from environmental factors is usually only mentioned in large-scale animal production. To understand the state of the literature on AMR in rural LA, we carried out a scoping review using the One Health (OH) perspective. OH recognises the concomitant contributions and interconnectedness of humans, animal, and the environment, thus, we used the OH perspective to select those articles adopting a holistic view of the problem. We searched original articles in English, Spanish, and Portuguese in four peer-reviewed databases and included 21 publications in the analysis. We charted data on bibliometrics, design, data collection sources, and instruments. We identified the human, animal, and environmental contributions to AMR in rural locations, and information gaps on AMR transmission routes and AMR drivers. Intensive and non-intensive animal production systems and agricultural practices were the most frequently found human contributions to AMR. Poultry, swine, cattle, and fish were the most frequent livestock mentioned as sources of AMR bacteria. Animal carriage and/or transfer of AMR determinants or bacteria was recognised as the primary contribution of livestock to the problem, while water, soil, and farming were predominant environmental contributions. We found that only 1 article out of 21 considered the OH approach as a framework for their sampling scheme, whereas 5 out 21 discussed all the three OH components. There were hardly any descriptions of humans or human waste as reservoirs for AMR in rural locations, and rural health centres or hospitals and wildlife were not represented. No studies identified mining as an anthropogenic activity driving AMR. More OH-oriented studies, with emphasis on molecular approaches—for identification and comparison of AMR genes—are sorely needed to understand better the existence of a network of interconnected transmission routes in rural Latin America and provide efficient strategies to prevent further AMR emergence.

Escherichia coli, Species C Human Adenovirus, and Enterovirus in Water Samples Consumed in Rural Areas of Goiás, Brazil

Rural environments lack basic sanitation services. Facilities for obtaining water and disposing sewage are often under the initiative of each resident, who may not be able to build and maintain them properly. Thus, water for human consumption is subject to fecal contamination and, consequently, the presence of waterborne pathogens, such as enteric viruses. This study evaluated fecal contamination of water samples from individual sources used for domestic water supply on small farms in the state of Goiás, Brazil. Samples were collected from 78 houses whose water sources were tubular wells, dug wells, springs, and surface waters. Escherichia coli (EC) bacteria, analyzed by the defined chromogenic substrate method, was used as a traditional indicator of fecal contamination. The enteric viruses Human mastadenovirus (HAdV) and Enterovirus (EV), analyzed by qPCR, were tested as complementary indicators of fecal contamination. At least one of these markers was found in 89.7% of the samples. Detection rates were 79.5% for EC, 52.6% for HAdV, and 5.1% for EV. The average concentration for EC was 8.82 × 10 1 most probable number (MPN) per 100 mL, while for HAdV and EV the concentrations were 7.51 × 10 5 and 1.89 × 10 6 genomic copies (GC) per liter, respectively. EC was the most frequent marker in ground and surface water samples. HAdV was detected significantly more frequently in groundwater than in surface water and was more efficient in indicating contamination in tubular wells. There was no association of frequencies or correlation of concentrations between EC and HAdV. HAdV indicated human fecal contamination and performed well as a complementary indicator. The results reveal that a large part of the analyzed population is vulnerable to waterborne diseases caused by enteric pathogens.
