Abstract
This research paper aimed to evaluate the association between feeding waste milk to calves and the occurrence of antimicrobial multi-resistance by extended spectrum β-lactamase (ESBL) enzymes through determining their production by E. coli isolates from 32 dairy farms. Among β-lactamase enzymes, ESBL provide resistance to a wide variety of β-lactam antimicrobials including penicillin and 2nd, 3rd and 4th generation cephalosporins. Feeding waste milk to calves has been observed to lead to increased antimicrobial resistance in faecal isolates of calves. In each farm included in this study, faecal samples were collected from the rectum of five healthy calves in the first month of life and pooled into a single container. Five isolates from each pool were selected and confirmed to be E. coli by amplification of the 16S rRNA gene. ESBL production was confirmed phenotypically on 148 isolates from 31 farms by use of the double-disk synergy test. Genotypic confirmation of ESBL production was performed by PCR for the genes blaCTX-M-1, -2, -8, -9 and blaCMY-2. A questionnaire was also performed and a mixed logistic regression model was used to identify risk factors for the occurrence of antimicrobial resistance. A negative binomial regression model was also used, in order to assess whether there was any association between certain farm management practices and the number of ESBL-producing E. coli isolates from each farm. Phenotypic confirmation of ESBL production was obtained on 40 E. coli isolates from 15 farms (48.4%), whereas genotypic confirmation was obtained on 55 isolates from 20 farms (64.5%). The use of three or more different intramammary antimicrobials to treat mastitis within the previous year significantly impacted the number of ESBL-producing E. coli isolates; on farms that did so, there were more isolates in which ESBL-producing E. coli was present, when compared to farms that had used less formulations within the same time span.

Front Microbiol 2019; 10:1941.

Abstract
In the last decade, extended-spectrum cephalosporin and carbapenem resistant Gram-negative bacilli (GNB) have been extensively reported in the literature as being disseminated in humans but also in animals and the environment. These resistant organisms often cause treatment challenges due to their wide spectrum of antibiotic resistance. With the emergence of colistin resistance in animals and its subsequent detection in humans, the situation has worsened. Several studies reported the transmission of resistant organisms from animals to humans. Studies from the middle east highlight the spread of resistant organisms in hospitals and to a lesser extent in livestock and the environment. In view of the recent socio-economical conflicts that these countries are facing in addition to the constant population mobilization; we attempt in this review to highlight the gaps of the prevalence of resistance, antibiotic consumption reports, infection control measures and other risk factors contributing in particular to the spread of resistance in these countries. In hospitals, carbapenemases producers appear to be dominant. In contrast, extended spectrum beta lactamases (ESBL) and colistin resistance are becoming a serious problem in animals. This is mainly due to the continuous use of colistin in veterinary medicine even though it is now abandoned in the human sphere. In the environment, despite the small number of reports, ESBL and carbapenemases producers were both detected. This highlights the importance of the latter as a bridge between humans and animals in the transmission chain. In this review, we note that in the majority of the Middle Eastern area, little is known about the level of antibiotic consumption especially in the community and animal farms. Furthermore, some countries are currently facing issues with immigrants, poverty and poor living conditions which has been imposed by the civil war crisis. This all greatly facilitates the dissemination of resistance in all environments. In the one health concept, this work re-emphasizes the need to have global intervention measures to avoid dissemination of antibiotic resistance in humans, animals and the environment in Middle Eastern countries.

WHO Global Priority Pathogens List: A Bibliometric Analysis of Medline-PubMed for Knowledge Mobilization to Infection Prevention and Control Practices in Bahrain. Oman Med J 2019; 34:184-193.

Abstract
Objectives In 2017, the World Health Organization (WHO) published a list of global priority pathogens (GPP) – 12 species of bacteria with critical, high, and medium antibiotic resistance (AR). In this review, our goal was to quantify published reports of AR in this group of pathogens using the Medline-PubMed databases. We also sought to quantify, compare and rank the top five reported AR pathogens globally, regionally and for Bahrain, and describe the evidence from Bahrain for the purpose of infection prevention and control, and to help research and development. Methods We conducted a bibliometric, retrospective, descriptive review to search the Medline-PubMed database for reports specific to the WHO GPP list published up to 19 April 2017. Results Our search revealed 42 136 documents with an increase in the last five years. Globally, there were more high tier pathogen documents (33 640) than critical (6405) and medium (2091). Methicillin-resistant Staphylococcus aureus (MRSA) was the highest reported, followed by extended-spectrum beta-lactamases (ESBL) resistant Enterobacteriaceae and vancomycin-resistant Enterococcus faecium. Nine out of the 12 pathogens were gram-negative. MRSA was the topmost documented pathogen globally and in the Gulf Cooperation Council (GCC) region zone of classification, whereas ESBL resistant Enterobacteriaceae ranked the top in Bahrain. There were two critical tier pathogens in the global, GCC region, and Bahrain. We found 14 articles from Bahrain, four articles on ESBL resistant Enterobacteriaceae, three on MRSA, two on carbapenem-resistant Acinetobacter baumannii, and five on different pathogens. Conclusions Our findings suggest the need for a comprehensive, multipronged policy response particularly at the time when the antibiotic pipeline is nearly empty. We recommend thoughtful, integrated infection prevention and control strategies to address the immediate and long-term threats of AR in Bahrain and the GCC.
