This study estimated the prevalence of Salmonella, Campylobacter, and Escherichia coli isolates in fresh retail grain-fed veal obtained in Ontario, Canada. The prevalence and antimicrobial resistance patterns were examined for points of public health significance. Veal samples (n = 528) were collected from February 2003 through May 2004. Twenty-one Salmonella isolates were recovered from 18 (4%) of 438 samples and underwent antimicrobial susceptibility testing. Resistance to one or more antimicrobials was found in 6 (29%) of 21 Salmonella isolates; 5 (24%) of 21 isolates were resistant to five or more antimicrobials. No resistance to antimicrobials of very high human health importance was observed. Ampicillin-chloramphenicol-streptomycin-sulfamethoxazole-tetracycline resistance was found in 5 (3%) of 21 Salmonella isolates. Campylobacter isolates were recovered from 5 (1%) of 438 samples; 6 isolates underwent antimicrobial susceptibility testing. Resistance to one or more antimicrobials was documented in 3 (50%) of 6 Campylobacter isolates. No Campylobacter isolates were resistant to five or more antimicrobials or category I antimicrobials. E. coli isolates were recovered from 387 (88%) of 438 samples; 1,258 isolates underwent antimicrobial susceptibility testing. Resistance to one or more antimicrobials was found in 678 (54%) of 1,258 E. coli isolates; 128 (10%) of 1,258 were resistant to five or more antimicrobials. Five (0.4%) and 7 (0.6%) of 1,258 E. coli isolates were resistant to ceftiofur and ceftriaxone, respectively, while 34 (3%) of 1,258 were resistant to nalidixic acid. Ciprofloxacin resistance was not detected. There were 101 different resistance patterns observed among E. coli isolates; resistance to tetracycline alone (12.7%, 161 of 1,258) was most frequently observed. This study provides baseline prevalence and antimicrobial resistance data and highlights potential public health concerns.

This study estimated the prevalence of Escherichia coli isolates in fresh retail milk-fed veal scallopini pieces obtained from grocery stores in Ontario, Canada. In addition, the prevalence and antimicrobial resistance patterns were examined for points of public health significance. One hundred fifty-three milk-fed veal samples were collected over the course of two sampling phases, January to May 2004 and November 2004 to January 2005. E. coli isolates were recovered from 87% (95% confidence interval, 80.54 to 91.83%) of samples, and antimicrobial susceptibility testing was conducted on 392 isolates. The prevalence of resistance to one or more antimicrobials was 70% (274 of 392), while the resistance to five or more antimicrobials was 33% (128 of 392). Resistance to ceftiofur (2.8%), ceftriaxone (3.6%), nalidixic acid (12%), and ciprofloxacin (3.8%) alone or in combination was observed. Eighty-five resistance patterns were observed; resistance to tetracycline only (7.4%) was observed most frequently. Individual antimicrobial resistance prevalence levels were compared with grain-fed veal and retail beef data from samples collected in Ontario. In general, resistance to individual antimicrobials was observed more frequently in E. coli isolates from milk-fed veal than in isolates from grain-fed veal and beef. Resistance to one or more antimicrobials and to five or more antimicrobials in E. coli isolates was more frequent in isolates from milk-fed veal than in isolates from grain-fed veal and beef. This study provides baseline data on the occurrence of resistance in E. coli isolates from milk-fed veal that can be compared with data for other commodities. Additionally, E. coli resistance patterns may serve as an indicator of antimicrobial exposure.

Susceptibility Profiles

Background: The ever-increasing magnitude of antimicrobial resistance encountered in human pathogens has led to limited treatment options for bacterial infections, consequently reducing antimicrobial efficacy while increasing treatment costs, morbidity, and mortality. In clinical setup, laboratory-based in vitro antimicrobial susceptibility testing is the cornerstone for guiding therapy and enables the monitoring of antimicrobial resistance trends. Aim: To characterize the distribution of bacteria isolated from various specimens and their antibiotic susceptibility profiles in Mary Begg Health facilities. Material & Methods: This was a retrospective, cross-sectional, quantitative, descriptive study that involved the review of 569 laboratory files from three Mary Begg Health facilities from the period of January 2019 to June 2020. A systematic random sampling method was used and SPSS version 21.0 was used for data analysis. Results: The distribution of bacteria based on Gram stain reaction found that most bacteria that were isolated were Gram negative bacilli, 79.5% (171/215). The most common bacterium isolated was Escherichia coli, 46.5% (100/215) followed by Staphylococcus aureus, 12.1% (26/215) and Klebsiella pneumoniae, 17 7.9% (17/215). The study found that E. coli was highly resistant to amoxicillin (95.0%), Ampicillin (90.0%) and Cotrimoxazole (77.0%), respectively. In contrast, E. coli was highly sensitive to Amikacin (96.0%), Ertapenem (91.0%) and Ceftriaxone (80.0%) S. aureus species isolated were sensitive to Gentamicin (65.4%) and Clindamycin (46.2%) but highly resistant to Cotrimoxazole (80.8%). Conclusion: The most frequent isolates were Escherichia coli followed by Staphylococcus aureus and majority of them were from urine specimens.

This study aimed to compare the antibiotic resistance levels of the indicator bacteria Escherichia coli in wastewater samples collected from two hospitals and two urban communities. Antimicrobial susceptibility testing was performed on 81 E. coli isolates (47 from hospitals and 34 from communities) using the disc diffusion method according to the European Committee on Antimicrobial Susceptibility Testing (EUCAST) methodology. Ten antibiotics from nine different classes were chosen. The strains isolated from the community wastewater, compared to those from the hospital wastewater, were not resistant to gentamicin (p = 0.03), but they showed a significantly higher susceptibility—increased exposure to ceftazidime (p = 0.001). Multidrug resistance was observed in 85.11% of the hospital wastewater isolates and 73.53% of the community isolates (p > 0.05). The frequency of the presumed carbapenemase-producing E. coli was higher among the community isolates (76.47% compared to 68.09%) (p > 0.05), whereas the frequency of the presumed extended-spectrum beta-lactamase (ESBL)-producing E. coli was higher among the hospital isolates (21.28% compared to 5.88%) (p > 0.05). The antibiotic resistance rates were high in both the hospital and community wastewaters, with very few significant differences between them, so the community outlet might be a source of resistant bacteria that is at least as important as the well-recognised hospitals.

Carriage Rate

Introduction: The nasals and hand carriage of Staphylococcus aureus in food handlers (FHs) represent a significant source of Staphylococcal food contamination and food poisoning. Antimicrobial resistance (AMR) is a microorganism’s ability to resist the action of one or more antimicrobial agents. S. aureus has demonstrated the ability to rapidly respond to each new antimicrobial with the development of a resistance mechanism. The aim of the study was to assess the prevalence of nasal carriage rate and AMR pattern of isolated strains S. aureus among FHs in Canton Sarajevo, Bosnia and Herzegovina. Methods: The retrospective study included laboratory results of 11.139 tested subjects between January 2014 and December 2018. The study was conducted in the laboratory of the Institute of Public Health of the Federation of Bosnia and Herzegovina in Sarajevo. Samples of nasal swabs were collected from FHs, employees in companies located in Canton Sarajevo, during sanitary surveillance prescribed by applicable legal standards. S. aureus isolates were identified according to conventional microbiological methods and antimicrobial susceptibility testing was performed by the agar disk diffusion method according to the European Committee on Antimicrobial Susceptibility Testing; 2013 standard. Results: Among the 11.138 subjects, 792 (7.1%) were carriers of S. aureus. Isolated strains were tested on eight different antibiotics, and the resistance to penicillin, ampicillin, and amoxicillin was 788 (99.5%), 776 (97.9%), and 752 (94.9%), retrospectively. In total, 86.36% of isolated strains were multidrug-resistant. Conclusions: The low percentage of S. aureus carriers indicates that preventive measures of carrier control are being actively implemented within the legally prescribed measures. The emergence of numerous isolated strains with multidrug-resistance characteristics is a significant public health problem and consequently limits the range of antibiotics available for therapeutic purposes. The results of this research indicate that AMR has increased in Sarajevo Canton and it is following the trend of global growth.

Antimicrobial Resistance Genes

Antimicrobial resistance is a public health concern worldwide and it is largely attributed to the horizontal exchange of transferable genetic elements such as plasmids carrying integrons. Several studies have been conducted on livestock showing a correlation between the systemic use of antibiotics and the onset of resistant bacterial strains. In contrast, although companion birds are historically considered as an important reservoir for human health threats, little information on the antimicrobial resistance in these species is available in the literature. Therefore, this study was aimed at evaluating the antimicrobial resistance of Escherichia coli and Pseudomonasaeruginosa isolated from 755 companion birds. Cloacal samples were processed for E. coli and P. aeruginosa isolation and then all isolates were submitted to antimicrobial susceptibility testing. P. aeruginosa was isolated in 59/755 (7.8%) samples, whereas E. coli was isolated in 231/755 (30.7%) samples. Most strains showed multidrug resistance. This study highlights that companion birds may act as substantial reservoirs carrying antimicrobial resistance genes which could transfer directly or indirectly to humans and animals, and from a One Health perspective this risk should not be underestimated.

Background and Aim: There is currently no published information on the prevalence and antimicrobial susceptibility patterns of commensal Escherichia coli in dogs of Grenada origin. Monitoring antimicrobial resistance helps in the empirical selection of antibiotics. This study determined the occurrence of E. coli including the O157:H7 serotype in feces of non-diarrheic dogs of Grenada origin and the antibiotic resistance pattern of the E. coli isolates. Materials and Methods: Fecal samples from 142 of the 144 (98.6%) dogs were culture positive for E. coli. Selection of up to three colonies from each of the 142 E. coli-positive samples yielded a total of 402 E. coli isolates, which were analyzed for the presence of non-sorbitol fermenting colonies, and O157-agglutination. Results: Of the 402 E. coli isolates, 30 (7.5%) were non-sorbitol fermenters. However, none of the 402 isolates gave a positive reaction (O157:H7) to the E. coli O157:H7 latex kit. Antimicrobial susceptibility tests against 12 antibiotics revealed low resistance rates to all the tested antibiotics except for tetracycline (Te) (23.4%), cephalothin (CF) (13.2%), and ampicillin (AM) (7.7%). Thirty-nine out of the 402 (9.7%), E. coli isolates were resistant to two or more antibiotics of different classes. Conclusion: This is the first report of isolation and antimicrobial susceptibilities of commensal E. coli from non-diarrheic dogs in Grenada. Some of the isolates (39/402 isolates, 9.7%) were resistant to multiple antibiotics. This study showed that presently, dogs in Grenada should not be considered a reservoir for the E. coli O157:H7 serotype and for multiple antibiotic-resistant E. coli strains. Among the 402 E. coli isolates, the resistance rate to drugs other than Te, CF, and AM was very low.

Dairy cattle are common carriers of important foodborne pathogens. Escherichia coli, Salmonella and Campylobacter jejuni are among the commonest causes of foodborne diseases. The high prevalence of microbial infections is escalating antimicrobial usage in human health and for growth promotion and prophylaxis in animal health. Overuse of antimicrobials is increasing antimicrobial residues in animal source foods and accelerating antimicrobial resistance. The study collected 184 samples from 33 dairy farms and assessed the prevalence of Escherichia coli, Salmonella and Campylobacter jejuni and their AMR. Sample inoculation for bacterial isolation was by agar surface streaking method and broth dilution. Escherichia coli was isolated on Chromogenic Coliform agar at 37°C for 24 hour forming dark blue colonies confirmed by Indole, Methyl Red, Voges-Proskauer and Citrate biochemical tests. Escherichia coli antimicrobial susceptibility testing was done by a single disc diffusion method against eight standard antibiotics. Sensitive, Intermediate and Resistant system was used for reporting antimicrobial susceptibility testing results. Escherichia coli was isolated in 21.7% samples, Campylobacter jejuni and Salmonella were absent. Escherichia coli was isolated in fecal samples from 48.5% of study farms, 56.9% of fecal and 4.8% of water samples and not isolated in all milk samples tested. All Escherichia coli isolates were susceptible to gentamycin, ciprofloxacin, cefoxitin and cefotaxime but 9 were resistant to ampicillin, oxacillin, ceftazidime, and ceftriaxone, produced 4 penicillinase and 1 beta-lactamase while 4 didn’t exhibit any specific resistance mechanism. Aminoglycosides, quinolones, and furans showed no resistance. When stratified by sample, 7 fecal Escherichia coli isolates showed resistance compared to 2 water isolates. All fecal and water isolates were resistant to oxacillin. The majority of Beta-lactamase and penicillinase producing isolates were from fecal samples. Oxacillin was widely resisted hence it should not be used in routine treatment of bacterial infections to avoid treatment failures. All Escherichia coli isolates were susceptible to gentamycin, ciprofloxacin, cefoxitin and cefotaxime, 9 were resistant to ampicillin, oxacillin, ceftazidime, and ceftriaxone, produced 4 penicillinase and 1 beta-lactamase. Aminoglycosides, quinolones, and furans showed no resistance. There is a need to conduct continuous professional development training programmes for veterinarians and veterinary paraprofessionals to promote prudent use of antimicrobials. Access and use of gentamycin, ciproflaxacin, cefoxitin and cefotaxime by dairy farmers and unqualified people should be restricted to prevent or delay resistance to these four.

Baseline Information

This study was conducted to investigate antimicrobial resistance profiles of Escherichia coli isolates from broiler chickens in Alberta, Canada. Cecal contents of broiler chickens from 24 flocks were collected at slaughter between January and March 2005 for culture and antimicrobial susceptibility testing against a panel of 15 antimicrobials using a broth microdilution technique. Of 600 E. coli isolates tested, 475 (79.2%) were resistant to one or more antimicrobials, 326 (54.3%) were resistant to three or more antimicrobials, 65 (10.8%) were resistant to five or more antimicrobials, and 15 (2.5%) were resistant to seven or more antimicrobials. The most common resistance was to tetracycline (69.2%), followed by streptomycin (48.2%), kanamycin (40.3%), and sulfisoxazole (38.0%). None of the E. coli isolates were resistant to amikacin, ceftriaxone, or ciprofloxacin. Of the isolates that were resistant to two or more antimicrobials, the most common multidrug resistance patterns were streptomycin-tetracycline (44.0%), streptomycin-sulfisoxazole-tetracycline (30.7%), and kanamycin-streptomycin-sulfisoxazole-tetracycline (23.5%). Resistance to tetracycline and kanamycin (odds ratio = 46.7, P = 0.0001) was highly associated, followed by resistance to streptomycin and sulfisoxazole (odds ratio = 12.0, P = 0.0001), and streptomycin and tetracycline (odds ratio = 10.3, P = 0.0001). The flock level prevalence of resistance varied from 16.7% for chloramphenicol to 100.0% for ampicillin, streptomycin, sulfisoxazole, and tetracycline. The results of this study provided baseline information on antimicrobial susceptibility of E. coli isolates of broiler chickens at slaughter in Alberta, which can serve as a bench mark for future research.

Fosfomycin Trometamol

ZusammenfassungDie Behandlung der akuten unkomplizierten Zystitis soll entsprechend nationaler und internationaler Leitlinien primär mit Fosfomycin-Trometamol, Nitrofurantoin, Nitroxolin oder Pivmecillinam erfolgen. Die weitaus meisten ambulant erworbenen Harnwegsinfektionen werden durch Escherichia coli verursacht. Pivmecillinam (X-SYSTO®) ist das oral verfügbare Prodrug des Penicillin-Derivats Mecillinam, das seit März 2016 wieder auf dem deutschen Markt zur Verfügung steht. Das Ziel der Studie war, den Anteil der Mecillinam-resistenten Stämme bei E. coli-Isolaten vor der Einführung von X-SYSTO® in Deutschland zu ermitteln.Im Rahmen einer In-vitro-Studie wurden die minimalen Hemmkonzentrationen (MHK) von Mecillinam für 494 E.-coli-Urinisolate (einschließlich multiresistenter Stämme) bestimmt. Die Bakterienisolate waren im Zeitraum Oktober bis Dezember 2013 in 25 Laboren von Patienten aus dem niedergelassenen Bereich gesammelt worden. Die Bewertung der Erregerempfindlichkeit als Mecillinam-sensibel (MHK ≤ 8 mg/l) bzw. resistent (MHK > 8 mg/l) erfolgte mithilfe der Grenzwerte des European Committee on Antimicrobial Susceptibility Testing (EUCAST).Die Konzentrationen von Mecillinam, die zur Hemmung von 50 % bzw. 90 % der getesteten Isolate benötigt wurden, betrugen 1 und 4 mg/l für Isolate mit dem Extended-Spektrum-β-Laktamase-Phänotyp und 0,25 und 4 mg/l für die übrigen Isolate. Insgesamt wurden 98 % der Isolate als Mecillinam-sensibel und 2 % als resistent bewertet.Die Ergebnisse stützen die Empfehlung, Pivmecillinam als eine primäre Option zur Erstlinientherapie der akuten unkomplizierten Zystitis zu betrachten.
