Poultry production has boomed in Bangladesh in recent years. The poultry sector has contributed significantly to meet the increased demand for animal source proteins in the country. However, increased use of antimicrobials and antibiotics appeared to be a significant threat to food safety in the poultry sector. The poultry drug and feed sellers are at the frontline position involving selecting and delivering the antimicrobials to the poultry farmers. Studies assessing the poultry drug and feed sellers’ knowledge, attitudes, and practices (KAPs) are limited. The current study aimed to assess the community poultry drug and feed sellers’ KAPs of antimicrobial use (AMU) and antimicrobial resistance (AMR) in some selected areas of Bangladesh. We determined the respondents’ (drug and the feed sellers) KAPs of AMU and AMR using a tested and paper-based questionnaire. The study demonstrated that most respondents have insufficient knowledge, less positive attitudes, and inappropriate practices regarding AMU and AMR. The factor score analysis further showed that the type of respondents and their years of experience, level of education, and training on the drug were the significant factors impacting the current knowledge, attitudes, and practices of AMU and AMR. The adjusted logistic regression analysis revealed that the drug sellers who completed their education up to 12th grade and had training on the drug had adequate knowledge of AMU and AMR. The data also showed that the drug sellers belong to the age group 31–35 and 36–40 years and who completed 12th grade had good attitudes on the same. Likewise, the analysis further determined that drug sellers belonging the age category 18–25 and 26–30 years, and interestingly, the respondents who completed education up to 12th grade, had better practices. Spearman’s rank-order correlation revealed a positive association between each pair of the KAPs scores for the respondents. The correlation was fair between knowledge–attitudes, knowledge–practices, and attitudes–practices. Based on the current study results, we recommend educational interventions and appropriate training for the poultry drug and feed sellers to raise awareness and to upgrade their current knowledge on the appropriate use of antimicrobials. This will ultimately lead to reducing the chances of developing AMR in the poultry sectors of the country.

Objective.Clinical practice guidelines and recommended practices to control use of antibiotics have been published, but the effect of these practices on antimicrobial resistance (AMR) rates in hospitals is unknown. The objective of this study was to examine relationships between antimicrobial use control strategies and AMR rates in a national sample of US hospitals.Design.Cross-sectional, stratified study of a nationally representative sample of US hospitals.Methods.A survey instrument was sent to the person responsible for infection control at a sample of 670 US hospitals. The outcome was current prevalences of 4 epidemiologically important, drug-resistant pathogens, considered concurrently: methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci, ceftazidime-resistant Klebsiella species, and quinolone (ciprofloxacin)-resistant Escherichia coli Five independent variables regarding hospital practices were selected from the survey: the extent to which hospitals (1) implement practices recommended in clinical practice guidelines and ensure best practices for antimicrobial use, (2) disseminate information on clinical practice guidelines for antimicrobial use, (3) use antimicrobial-related information technology, (4) use decision support tools, and (5) communicate to prescribers about antimicrobial use. Control variables included the hospitals' number of beds, teaching status, Veterans Affairs status, geographic region, and number of long-term care beds; and the presence of an intensive care unit, a burn unit, or transplant services. A generalized estimating equation modeled all resistance rates simultaneously to identify overall predictors of AMR levels at the facility.Results.Completed survey instruments were returned by 448 hospitals (67%). Four antimicrobial control measures were associated with higher prevalence of AMR. Implementation of recommended practices for antimicrobial use (P< .01) and optimization of the duration of empirical antibiotic prophylaxis (P<.01) were associated with a lower prevalence of AMR. Use of restrictive formularies (P = .05) and dissemination of clinical practice guideline information (P<.01) were associated with higher prevalence of AMR. Number of beds and Veterans Affairs status were also associated with higher AMR rates overall.Conclusions.Implementation of guideline-recommended practices to control antimicrobial use and optimize the duration of empirical therapy appears to help control AMR rates in US hospitals. A longitudinal study would confirm the results of this cross-sectional study. These results highlight the need for systems interventions and reengineering to ensure more-consistent application of guideline-recommended measures for antimicrobial use.

All infections are potentially curable as long as the etiological agents are susceptible to antimicrobials. The increased rate at which antimicrobials are becoming ineffective is a global health risk of increasing concern that threatens withdrawal of beneficial antimicrobials for disease control. The increased demand for food of animal origin, in particular eggs, meat and milk has led to intensification and commercial production systems where excessive use and misuse of antimicrobials may prevail. Antimicrobials, handled and used by farmers and animal attendants with no formal education, may be predisposed to incorrect dosages, misuse, incorrect applications and non-adherence to withdrawal periods. This study was conducted to assess the regulatory roles and governance of antimicrobials, establish the pattern and extent of their use, evaluate the antimicrobial residues and resistance in the food animals and crop agriculture value chains, and relate these findings to existing strategies in place for combating the emergence of antimicrobial resistance in Tanzania. A multimethod approach (desk review, field study and interviews) was used. Relevant establishments were also visited. High levels of resistance to penicillin G, chloramphenicol, streptomycin and oxytetracycline have been reported, especially for Actinobacter pyogenes, Staphylococcus hyicus, Staphylococcus intermedius and Staphylococcus aureus from dairy cattle with mastitis and in humans. Similar trends were found in poultry where eggs and meat are contaminated with Escherichia coli strains resistant to amoxicillin + clavulanate, sulphamethoxazole and neomycin. An increasing trend of emerging multidrug resistant E. coli, Klebsiella pneumoniae, Staphylococcus aureus and Salmonella was also found in food animals. An increase in methicillin resistant Staphlococcus aureus (MRSA) and extended-spectrum beta-lactamase (ESBL) in the livestock sector in Tanzania have been reported. The pathogens isolated in animals were resistant to ampicillin, augmentin, gentamicin, co-trimoxazole, tetracycline, amoxicillin, streptomycin, nalidixic acid, azithromycin, chloramphenicol, tylosin, erythromycin, cefuroxime, norfloxacin and ciprofloxacin. An increased usage of antimicrobials for prophylaxis, and therapeutics against pathogens and for growth promotion in livestock, aquaculture and crop production were observed. A One Health strategic approach is advocated to combat antimicrobial resistance (AMR) in the food and agriculture sectors in Tanzania. Practical recommendations include (a) legislation review and implementation; (b) antimicrobial use (AMU), AMR and antimicrobial residue (AR) awareness and advocacy among stakeholders along the value chain; (c) strengthening of surveillance and monitoring programs for AMU, AMR and AR; (d) enhanced development and use of rapid and innovative diagnostic tests and the promotion of biosecurity principles; and (e) good husbandry practices. The utilization of this information to improve public health policies and reduce the burden of AMR will be beneficial.

Abstract Background Antimicrobial resistance (AMR) is a global health threat affecting treatment outcome in animals and humans. A pre-requisite for development of AMR reduction strategies is knowledge of antimicrobial use patterns, and how these affect resistance development. The aim of this study was to determine antimicrobial usage (AMU) and whether such usage was associated with AMR in Salmonella from poultry farms in Northwest Nigeria. Results Fifteen (37%) of antimicrobial products observed contained compounds that are of highest priority and critically important for human medicine. Broilers chicken consumed higher (28 ± 14 mg/kg active ingredients) amounts of antimicrobials compared to layers (13 ± 8 mg/kg) per week (p = 0.0009). Surprisingly, chickens raised under backyard system consumed higher amounts of antimicrobials (34 ± 7 mg/kg) than poultry in other systems (p = 0.02). High levels of resistance to tetracycline (58%), sulphonamides (65%), ciprofloxacin (46%) and gentamicin (42%) correlated with high farm level usage of these antimicrobials, and there was a strong correlation (r = 0.9) between farm usage and resistance of isolates to the same antimicrobials (p = 0.03). Conclusion High AMU, including use of highest priority critically important antimicrobials was observed at poultry farms in Northwest Nigeria. AMU correlated with high levels of resistance. Communication of prudent use of antimicrobials to farmers and regulation to obtain reduction in AMU should be a priority.

BackgroundMedical curricula need to provide adequate knowledge on antimicrobial medicine use and antimicrobial resistance (AMR). Such knowledge is critical in shaping correct attitudes and perceptions among future prescribers. However, the extent of preparation provided by medical curricula remains unknown.AimThe current study sought to determine knowledge, attitude and perception on antimicrobial use and AMR among final year medical students in Malawi.MethodsA descriptive cross-sectional study was undertaken among all final year medical students at the College of Medicine, University of Malawi in 2016. Total population sampling and self-administered questionnaires were used. Data were entered using Microsoft Excel and analysed with Epi info. Descriptive analysis for categorical data was done using frequencies and proportions, and for continuous data using measures of central tendency.ResultsThe response rate in this study was 95%. The mean and median aggregated scores were 7.2 and 7, respectively, for the 11 knowledge questions. Over 88% of the respondents answered more than half of the knowledge questions correctly. Respondents agreed that antimicrobials are overused both at national (50; 69%) and at hospital (52; 72%) levels.ConclusionThis study reports high aggregated knowledge scores on antimicrobial use and resistance with wide variations on correct knowledge scores per question. The study further shows varying level in attitudes and perceptions among medical students. Overall, there were gaps on antimicrobial use and knowledge of AMR which the medical curriculum should addresses.

AbstractBackgroundAs the numbers of people with COVID-19 continue to increase globally, concerns have been raised regarding the widespread use of antibiotics for the treatment of COVID-19 patients and its consequences for antimicrobial resistance during the pandemic and beyond. The scale and determinants of antibiotic use in the early phase of the pandemic, and whether antibiotic prescribing is beneficial to treatment effectiveness in COVID-19 patients, are still unknown. Unwarranted treatment of this viral infection with antibiotics may exacerbate the problem of antibiotic resistance, while antibiotic resistance may render presumptive treatment of secondary infections in COVID-19 patients ineffective.MethodsThis rapid review was undertaken to identify studies reporting antimicrobial use in the treatment of hospitalised COVID-19 patients. The review was conducted to comply with PRISMA guidelines for Scoping Reviews (http://www.prisma-statement.org/Extensions/ScopingReviews) and the protocol was registered with the Open Science Framework (OSF): http://osf.io/vp6t5. The following databases: Web of Science, EMBASE, PubMed, CNKI & VIP were searched to identify the relevant studies from 1 Dec 2019 up to 15 June 2020; no limits were set on the language or the country where studies were conducted. The search terms used were: ((“Covid-19” or “SARS-CoV-2” or “Coronavirus disease 2019” or “severe acute respiratory syndrome coronavirus-2”) and ((“antibiotic prescribing” or “antibiotic use” or “antibiotic*”) or “antimicrobial *” or “antimicrobial therapy” or “antimicrobial resistance” or “antimicrobial stewardship”)). A total of 1216 records were identified through database searching and 118 clinical studies met the inclusion criteria and were taken into data extraction. A bespoke data extraction form was developed and validated through two independent, duplicate extraction of data from five Records. As all the included studies were descriptive in nature, we conducted descriptive synthesis of data and reported pooled estimates such as mean, percentage and frequency. We created a series of scenarios to capture the range of rationales for antibiotic prescribing presented in the included studies.ResultsOur results show that during the early phase of the pandemic, 8501 out of 10 329 COVID-19 patients (82·3%) were prescribed antibiotics; antibiotics were prescribed for COVID-19 patients regardless of reported severity, with a similar mean antibiotic prescribing rate between patients with severe or critical illness (75·4%) and patients with mild or moderate illness (75·1%). The top five frequently prescribed antibiotics for hospitalised COVID-19 patients were azithromycin (28·0 % of studies), ceftriaxone (17·8%), moxifloxacin (14·4%), meropenem (14·4%) and piperacillin/tazobactam (12·7%). The proportion of patients prescribed antibiotics without clinical justification was 51·5% vs 41·9 % for patients with mild or moderate illness and those with severe or critical illness respectively. Comparison of patients who were provided antibiotics with a clinical justification with those who were given antibiotics without clinical justification showed lower mortality rates (9·5% vs 13·1%), higher discharge rates (80·9% vs 69·3%) and shorter length of hospital of stay (9·3 days vs 12·2 days). Only 9·7% of patients in our included studies were reported to have secondary infections.ConclusionsAntibiotics were prescribed indiscriminately for hospitalised COVID-19 patients regardless of severity of illness during the early phase of the pandemic. COVID-19 related concerns and lack of knowledge drove a large proportion of antibiotic use without specific clinical justification. Although we are still in the midst of the pandemic, the goals of antimicrobial stewardship should remain unchanged for the treatment of COVID-19 patients.

Abstract Antimicrobial agents have been used in meat production for decades and its consumption is considered an key driver for the emergence and dissemination of antimicrobial resistance (AMR). However, large-scale studies on AMR changes in animal isolates since the introduction of antimicrobial usage remain scarce. We applied whole genome sequencing analysis to 982 animal-derived Escherichia coli collected in China from 1970s to 2019 and found increasing trends for the presence of numerous antimicrobial resistance genes (ARGs), including those conferring resistance to critically important agents for veterinary (florfenicol and norfloxacin) and human medicine (colistin, cephalosporins, and meropenem). Extensive diversity and increasing complexity of ARGs and their associated mobile genetic elements (MGEs) such as plasmids were also observed. The plasmids, IncC, IncHI2, IncK, IncI, IncX and IncF played a key role as highly effective vehicles for disseminating ARGs. Correlation analysis also revealed an association between antimicrobial production and emergence of ARGs at a spatial and temporal level. Prohibiting or strictly curtailing antimicrobial use in animals will potentially negate the current trends of AMR as the bacterial genome is highly changeable and using different drugs of the same class, or even unrelated classes, may co-select for MGEs carrying a plethora of co-existing ARGs. Therefore, limiting or ceasing antimicrobial use in animals to control AMR requires careful consideration.
