ABSTRACT Industrial farms are unique, human-created ecosystems that provide the perfect setting for the development and dissemination of antibiotic resistance. Agricultural antibiotic use amplifies naturally occurring resistance mechanisms from soil ecologies, promoting their spread and sharing with other bacteria, including those poised to become endemic within hospital environments. To better understand the role of enterococci in the movement of antibiotic resistance from farm to table to clinic, we characterized over 300 isolates of Enterococcus cultured from raw chicken meat purchased at U.S. supermarkets by the Consumers Union in 2013. Enterococcus faecalis and Enterococcus faecium were the predominant species found, and antimicrobial susceptibility testing uncovered striking levels of resistance to medically important antibiotic classes, particularly from classes approved by the FDA for use in animal production. While nearly all isolates were resistant to at least one drug, bacteria from meat labeled as raised without antibiotics had fewer resistances, particularly for E. faecium. Whole-genome sequencing of 92 isolates revealed that both commensal- and clinical-isolate-like enterococcal strains were associated with chicken meat, including isolates bearing important resistance-conferring elements and virulence factors. The ability of enterococci to persist in the food system positions them as vehicles to move resistance genes from the industrial farm ecosystem into more human-proximal ecologies. IMPORTANCE Bacteria that contaminate food can serve as a conduit for moving drug resistance genes from farm to table to clinic. Our results show that chicken meat-associated isolates of Enterococcus are often multidrug resistant, closely related to pathogenic lineages, and harbor worrisome virulence factors. These drug-resistant agricultural isolates could thus represent important stepping stones in the evolution of enterococci into drug-resistant human pathogens. Although significant efforts have been made over the past few years to reduce the agricultural use of antibiotics, continued assessment of agricultural practices, including the roles of processing plants, shared breeding flocks, and probiotics as sources for resistance spread, is needed in order to slow the evolution of antibiotic resistance. Because antibiotic resistance is a global problem, global policies are needed to address this threat. Additional measures must be taken to mitigate the development and spread of antibiotic resistance elements from farms to clinics throughout the world.

Background and Aim: Antibiotic resistance is one of the most serious problems worldwide. One predictive factor of increasing antibiotics resistance is the use of antibiotics in animals. This study aimed to explore the use of antibiotics for animal husbandry in a general community in Indonesia. Materials and Methods: A concurrent mixed-methods study was conducted. Data were collected from 407 respondents using a questionnaire, followed by an in-depth interview in 12 respondents. Data were analyzed both quantitatively and qualitatively. Results: Forty-two (10.32%) of 407 respondents used antibiotics for animal husbandry. Of these 42, >60% occasionally bought antibiotics from the pharmacy without prescription and 50% used their leftover antibiotics. Respondents also bought antibiotics from food stalls and animal feed shops. Tetracycline and amoxicillin were the most common antibiotics used for animal husbandry. The majority of respondents used antibiotics for therapeutic purposes and received information about using antibiotics for animal husbandry from friends and neighbors. Most of the respondents used antibiotics for animal husbandry incorrectly and had never heard of antibiotics resistance. Conclusion: Inappropriate antibiotic use in animal husbandry was common in the community. Education on the prudent use of antibiotics for animal husbandry is needed.

Animal Pathogens

Food safety is a term broadly applied to food quality that may adversely affect human health. There are two major areas of concern over the presence of residues of antibiotics in animal-derived foodstuffs with regard to human health. The first is allergic reaction and the second is development of antibiotic resistance in the gut bacteria of human. Antibiotic resistance in human pathogens is now a major public health issue. Some of the resistance problem can be attributed to the transfer of resistant bacteria from animals to human and the transfer of resistance genes from animal pathogens and commensal bacteria to human pathogens. Control measures include improvements in food hygiene to reduce the spread of zoonotic bacteria to human via the food chain. However, to specifically address the issue, the livestock industries and their advisors must reduce and refine the use of antibiotics in animal production and replace antibiotics with alternative disease control measures as much as possible. In addition, the medical profession must control misuse and overuse of antibiotics in hospitals and community practice. DOI: http://dx.doi.org/10.3329/bjas.v38i1-2.9909 BJAS 2009; 38(1-2): 22-32

Metagenomic Approach

AbstractDrug resistance has been partly driven by the overuse of antimicrobials in agricultural animal feed. Better understanding of antibiotic resistance in bovine gut is needed to assess its potential effects based on metagenomic approach and analysis. In this study, we collected 40 fecal samples to explore drug resistance derived from antibiotic use in the bacterial community by an analysis of the diversities and differences of antibiotic-resistant genes (ARGs) in the gut microbiota from yak, beef, and dairy cattle. Overall, 1688 genes were annotated, including 734 ARG subtypes. The ARGs were related to tetracyclines, quinolones, β-lactam, and aminoglycosides, in accordance with the antibiotics widely used in the clinic for humans or animals. The emergence, prevalence, and differences in resistance genes in the intestines of yaks, beef, and dairy cattle may be caused by the selective pressure of different feeding patterns, where yaks were raised without antibiotics for growth promotion. In addition, the abundance of ARGs in yak was lower than in beef and dairy cattle, whereas the abundance of integron, a kind of mobile genetic elements (MGEs) was higher in yaks than those in beef and dairy cattle. Furthermore, the results of this study could provide the basis for a comprehensive profile of various ARGs among yak, beef, and dairy cattle in future.

С течением времени подходы к изучению резистентности к антибиотикам трансформировались от сосредоточения на выделенных в виде чистой культуры патогенных микроорганизмах к исследованию резистентности на уровне микробных сообществ, составляющих биотопы человека и окружающей среды. По мере того, как продвигается изучение устойчивости к антибиотикам, возникает необходимость использования комплексного подхода для улучшения информирования мирового сообщества о наблюдаемых тенденциях в этой области. Все более очевидным становится то, что, хотя не все гены резистентности могут географически и филогенетически распространяться, угроза, которую они представляют, действительно серьезная и требует комплексных междисциплинарных исследований. В настоящее время резистентность к антибиотикам среди патогенов человека стала основной угрозой в современной медицине, и существует значительный интерес к определению ниши, в которых бактерии могут получить гены антибиотикорезистентности, и механизмов их передачи. В данном обзоре мы рассматриваем проблемы, возникшие на фоне широкого использования человечеством антибактериальных препаратов, в свете формирования микрофлорой кишечника резервуара генов резистентности. Over the time, studies of antibiotic resistance have transformed from focusing on pathogenic microorganisms isolated as a pure culture to analysis of resistance at the level of microbial communities that constitute human and environmental biotopes. Advancing studies of antibiotic resistance require an integrated approach to enhance availability of information about observed tendencies in this field to the global community. It becomes increasingly obvious that, even though not all resistance genes can geographically and phylogenetically spread, the threat they pose is indeed serious and requires complex interdisciplinary research. Currently, the antibiotic resistance of human pathogens has become a challenge to modern medicine, which is now focusing on determining a potential source for bacterial genes of drug resistance and mechanisms for the gene transmission. In this review, we discussed problems generated by the widespread use of antibacterial drugs in the light of forming a reservoir of resistance genes by gut microflora.

The Difference

The inappropriate use or misuse of antibiotics, particularly by outpatients, increases antibiotic resistance. A lack of public knowledge about “Responsible use of antibiotics” and “How to obtain antibiotics” is a major cause of this. This study aimed to assess the effectiveness of an educational video about antibiotics and antibiotic use to increase outpatients’ knowledge shown in two public hospitals in East Java, Indonesia. A quasi-experimental research setting was used with a one-group pre-test—post-test design, carried out from November 2018 to January 2019. The study population consisted of outpatients to whom antibiotics were prescribed. Participants were selected using a purposive sampling technique; 98 outpatients at MZ General Hospital in the S regency and 96 at SG General Hospital in the L regency were included. A questionnaire was used to measure the respondents’ knowledge, and consisted of five domains, i.e., the definition of infections and antibiotics, obtaining the antibiotics, directions for use, storage instructions, and antibiotic resistance. The knowledge test score was the total score of the Guttman scale (a dichotomous “yes” or “no” answer). To determine the significance of the difference in knowledge before and after providing the educational video and in the knowledge score between hospitals, the (paired) Student’s t-test was applied. The educational videos significantly improved outpatients’ knowledge, which increased by 41% in MZ General Hospital, and by 42% in SG General Hospital. It was concluded that an educational video provides a useful method to improve the knowledge of the outpatients regarding antibiotics.

Background: Antibiotic resistance is a global health crisis. The aim of this study was to explore dentists’ perceptions of antibiotic resistance. Methods: A qualitative method was used. Seventeen dentists practising in the Nancy (Lorraine, France) region were surveyed. They were general practitioners or specialised in oral surgery, implantology, or periodontology. The practitioners took part in semi-structured interviews between September 2019 and July 2020. All of the interviews were transcribed in full and analysed thematically. Results: Four major themes have been selected: attitudes of the dentists in regard to the guidelines, clinical factors that influence prescriptions, non-clinical factors that influence prescriptions, and the perception of antibiotic resistance. The dentists stated that they were very concerned regarding the public health issue of antibiotic resistance. However, they often prescribe according to their own interests and habits rather than according to the relevant guidelines. Conclusions: Although dentists are generally well aware of antibiotic resistance, they often do not adequately appreciate the link between their prescribing habits and the phenomenon of antibiotic resistance. Regular updating of practitioners’ knowledge in this regard is necessary, but patients and the general public should also be made more aware of the issue.

Background: Antimicrobials are used on dairy farms for preventing disease and treating common infections such as mastitis. Objective: We aimed to understand farmworker practices that potentially contribute to transmission of antimicrobial resistance bacteria and their genes (ARG) among animals and farm workers, and to identify human behavioral interventions to reduce risk. Methods: Focus groups with farm workers were held at 8 dairy farms across Wisconsin selected to represent a range of antibiotic use in cattle. We explored the nature of potentially high-risk practices and farm-worker knowledge and experiences with antibiotic use and resistance. Farm workers were asked to describe common tasks, including hand hygiene and eating practices, and the policies guiding these practices. Focus groups were conducted in English and Spanish guided by the Systems Engineering in Patient Safety (SEIPS) framework, adapted for an agricultural context. Discussions were recorded, transcribed, and translated. A content analysis was conducted to identify themes. Dedoose version 8.0.35 software was used to organize the data. Results: In total, 10 focus groups were conducted on 8 farms. Knowledge of when to use antibiotics for human health varied; upset stomach, headache, and flu symptoms were suggested as appropriate uses. Few workers had personal experience with antibiotic resistance at home or on the farm. Some displayed knowledge of the role of antibiotic stewardship in preventing the spread of ARG (“I guess all dairy farmers have a responsibility not to overdo it”). Others associated the risk of spread with the consumption of raw milk or meat from cows receiving antibiotics. Knowledge of personal protective equipment was stronger among workers who commonly reported glove use. Some perceived glove use to be mandatory, and others chose to wear gloves in the perceived absence of written rules. Some workers reported changing gloves numerous times throughout the day, and others did so less frequently or “only when they rip.” In general, hand hygiene practices are guided by individual knowledge of established rules, beliefs about risk, and personal discretion. Conclusions: Knowledge about mechanisms of spread of ARGs varies among workers on Wisconsin dairy farms and reflects a combination of farm-level rules, experience, individual knowledge, and beliefs. Applying knowledge from the healthcare setting to reduce ARG spread into agriculture is crucial to the tenets of One Health. Programs to reduce ARG spread on dairy farms should focus on proper hand hygiene and PPE use at the level of knowledge, beliefs, and practices.Funding: Funding: was provided by the USDA-NIFA Food Safety Challenge (grant no. 2017-68003-26500).Disclosures: None

More research is needed on the drivers of irrational antibiotic prescribing among healthcare professionals and to ensure effective prescribing and an adequate understanding of the issue of antibiotic resistance. This study aimed at evaluating prescribers’ knowledge, attitudes and behaviors about antibiotic use and antibiotic resistance. A cross-sectional study was conducted utilizing an online questionnaire and included physicians and dentists from all sectors in Jordan. A total of 613 prescribers were included (physicians n = 409, dentists n = 204). Respondents’ knowledge on effective use, unnecessary use or associated side effects of antibiotics was high (>90%), compared with their knowledge on the spread of antibiotic resistance (62.2%). For ease of access to the required guidelines on managing infections, and to materials that advise on prudent antibiotic use and antibiotic resistance, prescribers agreed in 62% and 46.1% of cases, respectively. 28.4% of respondents had prescribed antibiotics when they would have preferred not to do so more than once a day or more than once a week. Among respondents who prescribed antibiotics, 63.4% would never or rarely give out resources on prudent use of antibiotics for infections. The findings are of importance to inform antibiotic stewardships about relevant interventions aimed at changing prescribers’ behaviors and improving antibiotic prescribing practices.

Abstract Background Rational antibiotic prescribing is crucial to combat antibiotic resistance. Optimal strategies to improve antibiotic use are not known. Strama, the Swedish strategic program against antibiotic resistance, has been successful in reducing antibiotic prescription rates. This study investigates whether two specific interventions directed toward healthcare centers, an informational visit and a self-evaluation meeting, played a role in observed reduction in rates of antibiotic prescriptions in primary healthcare. Methods The study was a retrospective, observational, empirical analysis exploiting the variation in the timing of the interventions and considering past prescriptions through use of estimations from dynamic panel data models. Primary healthcare data from 2011 to 2014 were examined. Data were from public and private primary healthcare centers in western Sweden. The key variables were prescription of antibiotics and indicator variables for the two interventions. Results The first intervention, an educational information intervention, decreased the number of prescriptions among public healthcare centers, but this effect was only temporary. We found no proof that the second intervention, a self-evaluation meeting at the healthcare center, had an impact on the reduction of prescriptions. Conclusions Single educational interventions aimed at influencing rates of antibiotic prescriptions have limited impact. A multifaceted approach is needed in efforts to reduce the use of antibiotics in primary health care.
