Susceptibility of Escherichia Coli to 3-Lactam Antibiotics
ANTIMICROBIAL AGENTS AND CHEMOTHERAPY, Mar. 1994, p. 494-498 Vol. 38, No. 3 0066-4804/94/$04.00+0 Copyright © 1994, American Society for Microbiology Effect of Hyperproduction of TEM-1 1-Lactamase on In Vitro Susceptibility of Escherichia coli to 3-Lactam Antibiotics PEI-JUN WU,t KEVIN SHANNON,*t AND IAN PHILLIPS Department of Microbiology, United Medical and Dental Schools, St. Thomas' Hospital, London SE1 7EH, United Kingdom Received 21 July 1993/Returned for modification 4 November 1993/Accepted 4 January 1994 The susceptibility of 173 TEM-1-producing isolates of Escherichia coli was assessed by determination of MICs by the agar dilution method. MICs of amoxicillin, mezlocillin, cephaloridine, and, to a smaller extent, amoxicillin-clavulanic acid (but not cephalexin, cefuroxime, cefotaxime, ceftazidime, or imipenem) were higher for isolates that produced large amounts of f8-lactamase than for isolates that produced smaller amounts. The effect of fixed concentrations of clavulanic acid on resistance to amoxicillin was assessed for 34 selected TEM-1-producing isolates. Low concentrations of the inhibitor (0.5 to 1 ,ug/ml) reduced the amoxicillin MICs substantially for almost all the isolates, although the reductions were not sufficient to render any of the isolates amoxicillin susceptible. Higher concentrations of clavulanic acid had progressively greater effects on amoxicillin MICs, but even at 8 ,ug/ml some of the isolates with high P-lactamase activities remained resistant or only moderately susceptible to amoxicillin. All the isolates were inhibited by clavulanic acid (in the absence of amoxicillin) at concentrations of 16 to 32 ,ug/ml. TEM-1 ,-lactamase activity was inhibited in vitro by clavulanic acid, but not totally, with approximately 2% of the initial activity remaining at 2 ,ug/ml and 0.4% remaining at 8 ,guml. -
Antibiotic Use Guidelines for Companion Animal Practice (2Nd Edition) Iii

Danish copyright law restricts all other use without written permission of the publisher. Exception is granted for short excerpts for review purposes. iv Foreword The first edition of the Antibiotic Use Guidelines for Companion Animal Practice was published in autumn of 2012. The aim of the guidelines was to prevent increased antibiotic resistance. A questionnaire circulated to Danish veterinarians in 2015 (Jessen et al., DVT 10, 2016) indicated that the guidelines were well received, and particularly that active users had followed the recommendations. Despite a positive reception and the results of this survey, the actual quantity of antibiotics used is probably a better indicator of the effect of the first guidelines. Chapter two of these updated guidelines therefore details the pattern of developments in antibiotic use, as reported in DANMAP 2016 (www.danmap.org). -

I Farrukh Javaid Malik THESIS PRESENTED TO OBTAIN THE GRADE OF DOCTOR OF THE UNIVERSITY OF BORDEAUX Doctoral School, SP2: Society, Politic, Public Health Specialization Pharmacoepidemiology and Pharmacovigilance By Farrukh Javaid Malik “Analysis of the medicines panorama in Pakistan – The case of antimicrobials: market offer width and consumption.” Under the direction of Prof. Dr. Albert FIGUERAS Defense Date: 28th November 2019 Members of Jury M. Francesco SALVO, Maître de conférences des universités – praticien hospitalier, President Université de Bordeaux M. Albert FIGUERAS, Professeur des universités – praticien hospitalier, Director Université Autonome de Barcelone Mme Antonia AGUSTI, Professeure, Vall dʹHebron University Hospital Referee Mme Montserrat BOSCH, Praticienne hospitalière, Vall dʹHebron University Hospital Referee II Abstract A country’s medicines market is an indicator of its healthcare system, the epidemiological profile, and the prevalent practices therein. It is not only the first logical step to study the characteristics of medicines authorized for marketing, but also a requisite to set up a pharmacovigilance system, thus promoting rational drug utilization. The three medicines market studies presented in the present document were conducted in Pakistan with the aim of describing the characteristics of the pharmaceutical products available in the country as well as their consumption at a national level, with a special focus on antimicrobials. The most important cause of antimicrobial resistance is the inappropriate consumption of antimicrobials. The results of the researches conducted in Pakistan showed some market deficiencies which could be addressed as part of the national antimicrobial stewardship programmes.

Belgian Veterinary Surveillance of Antibacterial Consumption National
Belgian Veterinary Surveillance of Antibacterial Consumption National consumption report 2020 Publication : 22 June 2021 1 SUMMARY This annual BelVet-SAC report is now published for the 12th time and describes the antimicrobial use (AMU) in animals in Belgium in 2020 and the evolution since 2011. For the third year this report combines sales data (collected at the level of the wholesalers-distributors and the compound feed producers) and usage data (collected at farm level). This allows to dig deeper into AMU at species and farm level in Belgium. With a consumption of 87,6 mg antibacterial compounds/kg biomass an increase of +0.2% is seen in 2020 in comparison to 2019. The increase seen in 2020 is spread over both pharmaceuticals (+0.2%) and antibacterial premixes (+4.0%). This unfortunately marks the end of a successful reduction in antibacterial product sales that was seen over the last 6 years resulting in a cumulative reduction of -40,2% since 2011. The gap seen in the coverage of the sales data with the Sanitel-Med collected usage data increased substantially compared to 2019, meaning continuous efforts need to be taken to ensure completeness of the collected usage data. When looking at the evolution in the number of treatment days (BD100) at the species level, as calculated from the SANITEL- MED use data, use increased in poultry (+5,0%) and veal calves (+1,9%), while it decreased in pigs (-3,1%). However, the numerator data for this indicator remain to be updated for 2020, potentially influencing the reliability of the result. -

Appraisal of multifarious brands of Cephradine for their in vitro antibacterial activity against varied microorganisms Sajid Bashir1, Shamshad Akhtar1, Shahzad Hussain*2, Farnaz Malik2, Sidra Mahmood3, Alia Erum1 and Ume-Ruqiatulain1 1Department of Pharmacy, Sargodha University, Sargodha, Pakistan 2National Institute of Health, Islamabad, Pakistan 3Department of Bioinformatics and Biotechnology, International Islamic University, Islamabad, Pakistan Abstract: The astounding and exceptional growth of generic pharmaceutical Industry in Pakistan has raised certain questions for drug regulatory authorities contemplating their efficacy and quality. The current study focuses on assessing the in-vitro antimicrobial activity of 24 brands of Cephradine 500mg capsules against 4 different strains by employing standardized methods. Disk diffusion method was performed on all brands to look into the susceptibility and resistance patterns. Standard disk of 5µg Cephradine powder were used during evaluation. The zones of inhibitions were ranged from 24-40mm against S. aureus, 24-40mm against E. coli, 20-25mm against K. pneumonia and 19-23mm P. mirabilis. On the basis of mean value, the multinational brands were found to have better zone of inhibitions and were better than local Pharmaceutical companies but ANOVA cooperative study showed that all brands of Cephradine showed similar comparable results. Further investigations by employing MIC method, quality of raw material with special emphasis on the shelf-life, excepients and method of manufacturing will be needed to obtain more authenticated results. The price of National and Multinational brands ranges from Rs.156.00-212.00 for 10 capsules. It is concluded that Public health is at risk because of noticeable growing widespread curse of the manufacture and trade of sub-standard or below par pharmaceuticals. -
