Escherichia coli O157 : H7 (E. coli O157 : H7) has been found to be the major cause of food-borne diseases and a serious public health problem in the world, with an increasing concern for the emergence and spread of antimicrobial-resistant strains. Hitherto, little is known about the carriage of E. coli O157 : H7 and its antimicrobial susceptibility profile in the food of animal origin in Ethiopia. This study aimed to determine the occurrence and multidrug resistance profile of E. coli O157 : H7 from food of animal origin at different catering establishments in the selected study settings of Arsi Zone. One hundred ninety-two animal origin food items, namely, raw/minced meat (locally known as “Kitfo,” “Kurt,” and “Dulet”), raw milk, egg sandwich, and cream cake samples were collected and processed for microbiological detection of E. coli O157 : H7. Out of 192 samples, 2.1% (4/192) were positive for E. coli O157 : H7. Two E. coli O157 : H7 isolates were obtained from “Dulet” (6.3%) followed by “Kurt” (3.1%, 1/32) and raw milk (3.1%, 1/32), whereas no isolate was obtained from “Kitfo,” egg sandwich, and cream cake samples. Of the 4 E. coli O157 : H7 isolates subjected to 10 panels of antimicrobial discs, 3 (75%) were highly resistant to kanamycin, streptomycin, and nitrofurantoin. Besides, all the isolates displayed multidrug resistance phenotypes, 3 to 5 antimicrobial resistance, amid kanamycin, streptomycin, nitrofurantoin, tetracycline, and chloramphenicol. The occurrence of multidrug-resistant E. coli O157 : H7 isolates from foods of animal origin sampled from different catering establishments reveals that the general sanitary condition of the catering establishments, utensils used, and personnel hygienic practices did not comply with the recommended standards. Thus, this finding calls for urgent attention toward appropriate controls and good hygienic practices in different catering establishments dealing with consuming raw/undercooked foods of animal origin.

A cross-sectional study was conducted in small, medium, and large-scale dairy farms of Holeta district to isolate, identify, and antimicrobial susceptibility profile of Escherichia coli O157 : H7 in raw milk of dairy cattle. A total of 210 lactating cows were selected for raw milk samples, and 19% (40/210) were found to be positive for E. coli whereas 5.2% (11/210) were confirmed as E. coli O157 : H7 positive using the Escherichia coli O157 latex test. Accordingly, all E. coli was highly susceptible to Ciprofloxacin (100%), Gentamycin (100%), Oxytetracycline (100%), and Tetracycline (63.63%). Furthermore, the resistance of 72.73%, 54.54%, 54.54%, and 45.45% was developed to Cefoxitin, Sulphamethoxazole, Cloxacillin, and Streptomycin, respectively. Factors such as parity, age, body condition, herd size, milk yield, udder hygiene, and udder lesion showed a statistically significant ( p < 0.05 ) association with the occurrence of E. coli infection in dairy cattle. In conclusion, in this study, a higher prevalence of Escherichia coli O157 : H7 and its drug susceptibility profile is an alarm for the health of the public, and awareness creation to the farm owners and the community is recommended.

Summary: Antibiotic-resistant bacteria are emerging threat to the global public health. Estimates suggests >10 million deaths by 2050 due to AMR alone. Six Indian institute collaborated along with 4 UK universities to address the issue of antimicrobial resistance (AMR) through One Health approach under NEOSTAR project jointly funded by Department of Biotechnology (DBT), Government of India and UK Research and Innovation (UKRI), United Kingdom. To address a question “Dose AMR in livestock contributes to AMR in people? A pilot study was conducted which is a collaborative effort to collect archival microbial isolates of Escherichia coli, Klebsiella spp., Staphylococcus aureus and coagulase negative S. aureus (CoNS). The current study deals with E. coli isolates collected from ICAR-NIVEDI, ICAR-CIFT, ICAR-IVRI, ICAR-RCNEH, IIT-Delhi and GMCH and were subjected to QC analysis at ICAR-NIVEDI’s BSL2+ facility, these isolates were further segregated into 5 components viz., Animal origin (including aquaculture) (n=50) food of animal origin (n=30), Human (community settings) (n=3), Hospital origin (n=15) and Environment origin (n=14). A total of 112 E. coli isolates sequenced for whole genome through Illumina’s HiSeq 2500 platform at Sangers Institute, UK and paired end libraries were generated for all the 112 isolates were assembled and subjected to genome characterization and gene mining through various bioinformatics tools revealed the frequency of resistance, co-resistance, and resistant genes are high and similar across Human-Animal-Aquaculture-Environment continuum in India. This emphasizes the need to collaborate and mitigate antibiotic resistance with a ‘One Health’ approach.

Abstract Background: Escherichia coli O157:H7 is an emerging and major zoonotic foodborne pathogen with an increasing concern for the emergence and spread of antimicrobial-resistant strains which may results in sporadic cases to serious outbreaks in the whole world. Cattle have been identified as a major reservoir of the pathogen. This study aimed to isolate and characterize Shiga toxin-producing E. coli O157:H7 from raw milk, yogurt, and meat of bovine origin and determine their antimicrobial susceptibility pattern. Methods: A cross-sectional study was conducted from December 2014-June 2015 and a total of 284 milk and meat were collected from different sources in Mekelle. The collected samples were analyzed for the presence of E. coli and Shiga toxin-producing E. coli O157:H7 and determination of their antimicrobial susceptibility pattern following the standard bacteriological and molecular techniques and procedures, and antimicrobial sensitivity test. Results: Out of the total 284 samples, 70(24.64%) were positive bacteriologically to E. coli and 14.29% were found to be Shiga toxin-producing E. coli O157:H7. All (100%) E. coli isolates carried the pal and 41.67% eae gene (EHEC). Of these EHEC isolates 40% and 60% were positive for stx1 and stx2, respectively. E. coli isolates were showed the highest level of sensitivity for Gentamycin (91.7%) but the highest level of resistance to Amoxicillin (95.8%). Of the tested isolates, 18(75%) of E. coli showed multiple antimicrobial resistance.Conclusions: The current study revealed the occurrence of Shiga toxin-producing E. coli O157:H7 in foods of bovine origin in the study area. So, there is a chance of acquiring infection via the consumption of raw or undercooked food of bovine origin. Thus, awareness creation should be made on foodborne disease caused by Shiga toxin-producing E. coli O157:H7 with due consideration on the safe handling and consumption of food of animal origin.

The antimicrobial susceptibility ofEscherichia coliisolates associated with various types of infections in dogs and cats was determined. The studied isolates were most frequently susceptible to fluoroquinolones and the extended-spectrum cephalosporins (ESCs), antimicrobials commonly used in treatment of infections in companion animals. However, an increase in the percentage of strains resistant toβ-lactam antibiotics including ESCs was noted between January 2007 and December 2013. The frequency of multidrug-resistant (MDR)E. coliisolation (66.8% of isolates) is alarming. Moreover, the statistically significant increase of the percentage of MDR isolates was observed during the study period. No difference in the prevalence of multidrug resistance was found between bacteria causing intestinal and extraintestinal infections and between canine and feline isolates. NonhemolyticE. coliisolates were MDR more often than hemolytic ones. Our study showed the companion animals in Poland as an important reservoir of MDR bacteria. These results indicate that continuous monitoring of canine and felineE. coliantimicrobial susceptibility is required. Furthermore, introduction and application of recommendations for appropriate use of antimicrobials in small animal practice should be essential to minimize the emergence of multidrug resistance amongE. coliin companion animals.

Abstract Objectives The emergence of colistin-resistant Enterobacteriaceae from human and animal sources is one of the major public health concerns as colistin is the last-resort antibiotic for treating infections caused by multidrug-resistant Gram-negative bacteria. We aimed to determine the prevalence of the prototype widespread colistin resistance genes (mcr-1 and mcr-2) among commensal and pathogenic Escherichia coli strains isolated from food-producing and companion animals in Iran. Results A total of 607 E. coli isolates which were previously collected from different animal sources between 2008 and 2016 used to uncover the possible presence of plasmid-mediated colistin resistance genes (mcr-1 and mcr-2) by PCR. Overall, our results could not confirm the presence of any mcr-1 or mcr-2 positive E. coli among the studied isolates. It is concluded that despite the important role of food-producing animals in transferring the antibiotic resistance, they were not the main source for carriage of mcr-1 and mcr-2 in Iran until 2016. This study suggests that the other mcr variants (mcr-3 to mcr-9) might be responsible for conferring colistin resistance in animal isolates in Iran. The possible linkage between pig farming industry and high level of mcr carriage in some countries needs to be clarified in future prospective studies.

The status of Salmonella and its antimicrobial susceptibility profile in animal origin food items from different catering establishments in Ethiopia is scarce. Hence, this study aimed to investigate the occurrence and antimicrobial susceptibility profile of Salmonella isolates from animal origin food items in the selected areas of Arsi Zone. One hundred ninety-two animal origin food samples were collected and processed for Salmonella isolation. Isolates were tested for their susceptibility to 13 antimicrobials using Kirby–Bauer disk diffusion assay. An overall prevalence of 9.4% (18/192) Salmonella spp. isolates were recovered from animal origin food samples collected from different catering establishments. Seven (21.9%) of “Dulet,” 4 (12.5%) of “Kitfo,” 3 (9.4%) of “Kurt,” 2 (6.3%) of raw milk, 1 (3.1%) of egg sandwich and 1 (3.1%) of cream cake samples were positive for Salmonella. Catering establishments, protective clothing, source of contamination, manner of hand washing, and money handling were among the putative risk factors that were significantly associated ( p < 0.05 ) with Salmonella spp. occurrence. Ampicillin, nitrofurans, and sulphonamide resistance were significantly associated ( p < 0.05 ) with Salmonella spp. occurrence in the selected food items. Three (16.7%), 5 (27.8%), 5 (27.8%), and 4 (22.2%) of the isolates were resistant to 3, 4, 5, and 6 antibiotics, respectively, whereas only a sole isolate was resistant to two antibiotics (viz. ampicillin and kanamycin). In conclusion, the general sanitary condition of the catering establishments, utensils used, and personnel hygienic practices were not to the recommended standards in the current study. Besides, detection of multidrug-resistant strains of Salmonella in animal origin food items from different catering establishments suggests the need for detailed epidemiological and molecular characterization of the pathogen so as to establish the sources of acquisition of resistant Salmonella strains. Hence, implementation of Salmonella prevention and control strategies from farm production to consumption of animal origin food items are crucial.

Objectives/Aim: Urinary tract infections (UTI) are a serious public health problem and caused by many pathogens, most often by Escherichia coli and Klebsiella pneumoniae.Aim of this study was to show the frequency and antimicrobial susceptibility pattern of E. coli and K. pneumoniae in hospital isolates, following the GLASS methodology.Methods: This is a retrospective study that was conducted in the Laboratory for Urinary Infections OU Clinical Microbiology CCUS in the period from January till December 2018.A total of 13760 urine samples were processed, using standard laboratory methods, in which significant bacteriuria was detected in 3218 (23.4%) of specimens.Results: Out of the total number of positive samples, E. coli was isolated in 1166 (36.2%) and K. pneumoniae at 341 (10.6%) patients. The presence of E. coli and K. pneumoniae isolates is dominant in females (1103/73.2%) and age group 60 and older (812/54.7%). Out of the total E. coli isolates, the ESBL strain was presented with 79 (6.8%) and K. pneumoniae with 145 (42.5%). The proportion of carbapenemase (CPE) produced by K. pneumoniae isolates was 8 (2.4%). The ESBL strain distribution analysis on clinics showed the highest prevalence of both isolates at the Clinic for Nephrology: K. pneumoniae 26/17,9%; E. coli: 12/15.4%. Isolated E. coli showed the highest resistance to ampicillin 673/1166 (57,7%), trimethoprim-sulfamethoxazole 454/1166 (38.9%) and ciprofloxacin 253/970 (26.1%), while K. pneumoniae to ciprofloxacin and trimethoprim-sulfamethoxazole with 151/285 (53.0%) and 164/341 (48.1%), respectively.Conclusions: Our study has shown that the most common cause of urinary infections in hospital settings are E. coli and K. pneumoniae. Data analysis showed that the presence of ESBL isolates was significantly higher in K. pneumoniae than E. coli. CPE isolates of K. pneumoniae were also detected.

Food Of Animal Origin

Background. Salmonella has been recognized as a major cause of food-borne illness associated with the consumption of food of animal origin. The present cross-sectional study was conducted from December 2017 to May 2018 in Ambo and Holeta towns to assess the prevalence, risk factors, and antimicrobial susceptibility patterns of nontyphoidal Salmonella isolates from raw beef samples from abattoirs, butchers, and restaurants in Ambo and Holeta towns, Oromia region, Ethiopia. Methods. A total of 354 beef samples were collected from abattoirs, butchers, and restaurants. Salmonella isolation and identification were carried out using standard bacteriological methods recommended by the International Organization for Standardization. Antimicrobial susceptibility testing was performed using the disk diffusion method. Besides, a structured questionnaire was used to collect sociodemographic data and potential risk factors for contamination of meat. Chi-square tests and logistic regression were used for data analyses. Results. Of the total 354 meat samples examined, 20 (5.7%, 95% confidence interval (CI): 3.5–8.6) were positive for Salmonella. Two serotypes belonging to S. typhimurium (11 isolates) and I:4,5,12: i:- (9 isolates) were identified. The Salmonella detection rate in abattoirs, butchers, and restaurants was 4.2% (5/118), 8.5% (10/118), and 4.2% (5/118), respectively. The antimicrobial susceptibility test showed that 40%, 30%, and 20% of the Salmonella isolates were resistant to azithromycin, amoxicillin, and ceftriaxone, respectively. The odds of Salmonella isolation when meat handlers are illiterate were 7.8 times higher than those when they are educated to the level of secondary and above ( P = 0.032 ). Similarly, the likelihood of Salmonella isolation was 6.3 and 7.6 times higher among workers of butcher and restaurants, respectively, who had no training ( P = 0.003 ) and no knowledge ( P = 0.010 ) on food safety and hygiene. Conclusions. The study showed widespread multidrug-resistant Salmonella isolates in the study areas. Therefore, raw meat consumption and indiscriminate use of antimicrobial drugs should be discouraged. Provision of food safety education for meat handlers and further surveillance of antimicrobial-resistant isolates are suggested.

Objectives: The study aimed to search for E. coli O157 and non-O157 in milk, meat and faeces of cattle, sheep and pigs slaughtered in Cotonou. Methodology and Results: One hundred and Seventy-Five (175) samples including 25 meat, 25 faeces per species and 25 milk from cattle were analysed for E. coli O157; O26 and O111 and the virulence genes were identified by PCR. The SAS software (1998) and the bilateral Z test were used to calculate and compare the identification frequencies. E. coli O157 was identified in 4% of cattle faeces, 4% of sheep faeces, and 20% of beef and, in 20% of milk samples. E. coli O26 was identified in 12% of cattle faeces and, in 8% of beef samples. E. coli O111 was identified at frequencies of 8%, and 12% in faeces of sheep and pigs, respectively. The eae gene was detected in 4% of beef, ovine meat, milk, pig faeces and in sheep faeces. stx1 was detected in 8% of milk, and in 4% of bovine and sheep faeces. The strains possessing the gene were all of E. coli O157 with the exception of one from pig faeces identified as O111. Conclusions and application of findings: The presence of these serogroups of E. coli with virulence genes poses a real food safety problem in Benin. This study findings must be taken into account for risk assessment and management related to the consumption of food of animal origin. Keywords: Benin, E. coli O157, O26, O111, faeces, meat, milk
