Abstract Background: Antibiotic resistance is a public health concern in Democratic Republic Congo and worldwide. It is usually caused by antibiotic over prescription or dispensing practices. The consumption of animal source food (ASF) could be another source of antibiotic resistance but is rarely studied. The objective of the study was to evaluate the eating habits of ASF by outpatients with antimicrobial resistance through an analysis of (i) the association of their antimicrobial resistance with ASF consumption; (ii) the influence of the types of ASF on their antimicrobial resistance.Methods: This is a retrospective analytical study conducted at three major Hospitals in Bukavu City (D. R. Congo). A total number of 210 patients, whose samples (mainly faeces and urine) had been subjected to bacterial examination, was included in this study. Morphological, biochemical and antibiotic susceptibility (using disc diffusion method) tests were performed on the samples. This served to isolate and identify resistant bacteria. Afterwards, patients responded to questions about the types and quantity of ASF eaten in the last week. We analysed data using descriptive statistics, logistic regression and non-parametric ranking tests.Results: Escherichia coli (37.1%), Klebsiella pneumonae (14.7%), and Staphylococcus aureus (13.8%) were the most prevalent bacteria. E. coli (68.4%) and K. pneumonae (87.5%) were multidrug resistant (MDR), while S. aureus (7.7%) was minor. Low beef (O.R. 0.737, C.I. 0.542-1.002) and pork (O.R. 0.743, C.I. 0.560 – 0.985) consumption led to significantly (p<0.05) lower risks of resistance to ciprofloxacin. Patients eating three different ASF per week had the highest resistance score (20.67) and high consumption rates of goat meat, pork and milk (41.5%). Conclusion: The findings of this study suggest a contribution of human nutrition to antimicrobial resistance frequency. Our results show the existence of a high prevalence of multi-drug resistant bacteria in patients frequently consuming ASF in Bukavu. Therefore, a stricter control of antibiotic usage in livestock production and of their presence in ASF is recommended.

The current study investigated the impact of chicken litter application on the abundance of multidrug-resistant Enterococcus spp. in agricultural soil. Soil samples were collected from five different strategic places on a sugarcane farm before and after manure application for four months. Chicken litter samples were also collected. Enterococci were enumerated using the Enterolert®/Quanti-Tray 2000® system and confirm and differentiated into species using real-time PCR. The antibiotic susceptibility profile of the isolates was determined using the disk diffusion method following the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines. The overall mean bacterial count was significantly higher (p < 0.05) in manure-amended soil (3.87 × 107 MPN/g) than unamended soil (2.89 × 107 MPN/g). Eight hundred and thirty-five enterococci (680 from soil and 155 from litter) were isolated, with E. casseliflavus being the most prevalent species (469; 56.2%) and E. gallinarum being the least (16; 1.2%). Approximately 56% of all the isolates were resistant to at least one antibiotic tested, with the highest resistance observed against tetracycline (33%) and the lowest against chloramphenicol (0.1%); 17% of E. faecium were resistant to quinupristin-dalfopristin. Additionally, 27.9% (130/466) of the isolates were multidrug-resistant, with litter-amended soil harbouring more multidrug-resistant (MDR) isolates (67.7%; 88/130) than unamended soil (10.0%; 13/130). All isolates were susceptible to tigecycline, linezolid and gentamicin. About 7% of the isolates had a multiple antimicrobial resistance index > 0.2, indicative of high antibiotic exposure. Although organic fertilizers are regarded as eco-friendly compared to chemical fertilizers for improving soil fertility, the application of untreated animal manure could promote the accumulation of antibiotics and their residues and antibiotic-resistant bacteria in the soil, creating an environmental reservoir of antimicrobial resistance, with potential human and environmental health risks.

ABSTRACT Enterobacteria may gain antibiotic resistance and be potent pathogens wherever they are present, including in fresh fruits and vegetables. This study tested the antibiotic resistance of enterobacteria isolated from 13 types of local and imported fresh fruits and vegetables (n = 105), using the standard Kirby-Bauer disk diffusion method. Phenotypic and genotypic characterizations of AmpC β-lactamases were determined in cefoxitin-resistant isolates. Ten percent of the enterobacteria tested (n = 88) were pansusceptible, 74% were resistant to at least one antibiotic, and 16% were multidrug resistant. Enterobacteria isolates showed the highest antibiotic resistance against ampicillin (66%), cephalothin (57%), amoxicillin–clavulanic acid (33%), cefoxitin (31%), tetracycline (9%), nalidixic acid (7%), trimethoprim (6%), and kanamycin (5%). Three isolates showed intermediate resistance to the clinically important antibiotic imipenem. Escherichia coli isolated from lettuce exhibited multidrug resistance against five antibiotics. Fifteen isolates were confirmed to have AmpC β-lactamase, using the inhibitor-based test and the antagonism test; the latter test confirmed that the enzyme was an inducible type. Four types of ampC β-lactamase genes (CIT, EBC, FOX, and MOX) were detected in eight isolates: four Enterobacter cloacae isolates and one isolate each of Citrobacter freundii, Enterobacter asburiae, Enterobacter hormaechei, and Enterobacter ludwigii. It was concluded that fresh fruits and vegetables might play a role as a source or vehicle for transferring antibiotic-resistant bacteria that might spread to other countries through exportation. The clinically significant AmpC β-lactamase was rarely documented in the literature on bacteria isolated from fruits and vegetables, and to our knowledge, this is the first report on the detection of an inducible type in such commodities.

Abstract Background: Surgical site infections are related to high morbidity, mortality and healthcare costs. As the emergence of multidrug-resistant bacterial pathogens in hospitals is becoming a worldwide challenge for surgeons who treat healthcare-associated infections, we wished to identify the causative agents involved in surgical site infections and their susceptibility pattern in six public hospitals in Benin. Methods: Using standard microbiological procedures, we processed pus specimens collected from obstetrics and gastrointestinal surgery wards. Mass spectrometry (MALDI-TOF) was used for confirmation. The antibiotic susceptibility test firstly used the Kirby-Bauer disc diffusion method. The secondary test by microdilution used the Beckton Dickinson Phoenix automated system (Becton Dickinson Diagnostic, USA). Results: We included 304 patients (mean age 32 ± 11 years), whose median length of stay was 9 days. A total of 259 wound swabs (85.2%) had positive aerobic bacterial growth. In obstetrics S. aureus (28.5%, n=42) was the most common isolate. In contrast, Gram-negative bacteria (GNB) were predominant in gastrointestinal surgery. The most dominant being E.coli (38.4%, n=31). Overall, 90.8% (n=208) of aerobic bacteria were multidrug resistant. Two-third of S. aureus (65.3%, n= 32) were methicillin-resistant Staphylococcus aureus (MRSA), three of which carried both MRSA and induced clindamycin resistance (ICR). GNB showed high resistance to ceftazidime, ceftriaxone and cefepime. Extended-spectrum beta-lactamases were presented by 69.4% of E.coli (n=43/62) and 83.3% of K. pneumoniae (n=25/30). Overall, twelve Gram negative bacteria (5.24%) isolates showed resistance to at least one carbapenem. No isolates showed a wild-type susceptible phenotype.Conclusion: This study shows the alarming prevalence of multidrug resistant organisms from surgical site infections in Benin hospitals. To reduce the spread of these multidrug-resistant bacteria, periodic surveillance of surgical site infections and strict adherence to good hand-hygiene practice are essential.

Aim: Prevalence of multidrug resistant bacteria on apparently health animals has turned antibiotic resistance to multifaceted process and threatens global food security and public health. The aim of the present study was to investigate the resistance profile of isolates from apparently healthy cattle in Maiduguri, Nigeria. Methodology: A total of 120 nasal swab samples were collected from cattle. Colony identification was according to the guidelines of Bergey’s Manual of Determinative Bacteriology. The susceptibility pattern of the isolates was conducted on the identified isolates according to the Modified Kirby-Baur disc diffusion method on Muller-Hilton agar and interpreted according to the procedures of Clinical Laboratory Standards Institute (CLSI, 2018) guidelines. Multiple Antibiotic Resistance Index (MARI) was calculated using the formula, MARI=a/b where “a” is the number of antibiotic resisted and “b” is the total number of antibiotic used in the study. Results: Of the total samples (120) from cattle 96 (80%) detected the following isolates; E. coli was the most commonly recovered isolates (33, 34.4%), followed by Klebsiella spp (28, 29.2%), Salmonella spp (21, 21.9%) and Pseudomonas aeruginosa (14, 14.5%). In this study, all the recovered isolates were found to be multidrug resistant gram negative bacteria, with highest resistance was shown by Salmonella spp. The high MARI observed in all the isolates in this study ranging from 0.7 to 0.9. MARI value of 0.2 > is suggests multiple antibiotic resistant bacteria and indicate presence of highly resistant bacteria. Conclusion: The study indicates highly resistant bacteria are carried by healthy food animals. Thus, there is need for continued monitoring of antibiotics use in animal husbandry to prevent further spread of resistance in Maiduguri, Nigeria.

Antibiotics are one of the most significant advancements of modern medicine. They have changed the prognosis of several bacterial infections, and made possible advanced medical practices associated with a high risk of infectious complications. Unfortunately, antibiotics are affected by the phenomenon of antibiotic resistance, which jeopardizes their efficacy. In recent years, antibiotic discovery and development has been lagging, due to a lower appeal of this sector for the pharmaceutical industry, while antibiotic resistance has continued to evolve with the eventual emergence and dissemination of bacterial strains which are resistant to most available antibiotics and pose a major challenge to antimicrobial chemotherapy. This worrisome scenario, indicated as the “antibiotic resistance crisis”, has been acknowledged by Scientific Societies and Public Health Agencies, and is now gathering an increasing attention from the Media and Governments. This article reviews the antibiotic-resistant pathogens which currently pose major problems in terms of clinical and epidemiological impact, and briefly discuss future perspective in this field.

AbstractAntibiotic resistance has emerged as a key determinant of outcome in patients with serious infections along with the virulence of the underlying pathogen. Within the intensive care unit (ICU) setting, ventilator-associated pneumonia (VAP) is a common nosocomial infection that is frequently caused by multidrug-resistant bacteria. Antimicrobial resistance is a growing challenge in the care of critically ill patients. Escalating rates of antibiotic resistance add substantially to the morbidity, mortality, and cost related to infection in the ICU. Both gram-positive organisms, such as methicillin-resistant Staphylococcus aureus and vancomycin-intermediate S. aureus, and gram-negative bacteria, including Pseudomonas aeruginosa, Acinetobacter species, carbapenem-resistant Enterobacteriaceae, such as the Klebsiella pneumoniae carbapenemase–producing bacteria, and extended spectrum β-lactamase organisms, have contributed to the escalating rates of resistance seen in VAP and other nosocomial infections. The rising rates of antimicrobial resistance have led to the routine empiric administration of broad-spectrum antibiotics even when bacterial infection is not documented. Moreover, there are several new broader-spectrum antibiotics that have recently become available and others scheduled for approval in the near future. The challenge to ICU clinicians is how to most effectively utilize these agents to maximize patient benefits while minimizing further emergence of resistance. Use of rapid diagnostics may hold the key for achieving this important balance. There is an urgent need for integrating the administration of new and existing antibiotics with the emerging rapid diagnostic technologies in a way that is both cost-effective and sustainable for the long run.

Aims: Multidrug resistant (MDR) bacteria pose a major public health issuer globally. The genes for antibiotic resistance are transferred vertically in the form of genomic DNA and horizontally in the form of plasmids or transposons. Antibiotic are extensively used in animal farming to treat and prevent animal diseases, and at sub-therapeutic doses, they are used to promote animal growth. This extensive use of antibiotics is causing an increase in resistance among bacteria. More frequent, chicken meat available at retail shops is reported to be contaminated with a variety of drug resistant bacteria including E. Coli. The aim of the present study was to investigate antibiotic resistance in Escherichia coli strains isolated from chicken meat available in the local shops of Rafha, Saudi Arabia. Place and Duration of Study: Department of basic health sciences, College of Pharmacy, Northern Border University, Rafha, Saudi Arabia, between February and October, 2019 Methodology: Eighty-six E. coli strains, isolated from chicken meat, were tested for their antibiotic resistance profile, using the disc diffusion method.    Results: All the isolated E. coli strains were tested against 14 antibiotics. The maximum resistance was found against penicillin G (95%) followed by amoxicillin (85%), Cephalothin (81%), Erythromycin (72%), and Tetracycline (50%). Imipenem was the most effective agent of all with only 1% resistance followed by Cefepime with almost 6% resistance. A high percentage of the isolates (57%,) were multidrug resistant as they were non—susceptible to at least one antimicrobial in ≥3 antimicrobial classes including amoxicillin, erythromycin and tetracycline. Conclusion: The prevalence of MDR E. coli in retail chicken meat is very high and could pose a serious threat to public health.

Background: Emergence of multidrug-resistant uropathogenic strains mainly the global spread of extended-spectrum betalactamase (ESBL) genes accompanied both by uncontrolled use of antibacterial agents and a considerable decrease in their activities makes the monitoring of the resistance pattern one of necessary means that could help the medical practitioners to choose the best treatment. For this purpose and during four months from March 1 to June 30 (2019), an experimental study has been carried out on urine specimens of 123 inpatients (IP) and outpatients (OP) at infectious disease service Boudjemaa TOURABI Public Hospital of Bechar (Algeria), aiming the detection of ESBL-producing Enterobacteriaceae uropathogenic strains. Methods: Firstly, the antibiotic susceptibility testing has been carried out by using the disk diffusion method to determine not only the multidrug resistance patterns, but also the multiple antibiotic resistance indexes of uropathogenic strains isolated from clinical IP and OP samples. Secondly, the ESBL detection was done by using the following methods: synergy tests based on the synergy between a thirdgeneration cephalosporin and clavulanate, double-disc synergy test (DDST) and phenotypic tests on a cloxacillin-containing agar. Results: As a result, 56 patients had a urinary tract infection (UTI) in overall 123 patients; a frequency of 45,52%. Through a UTI’s frequency of 64,7%, the female gender was the most affected. All age groups were affected by UTI, with a mean age of 38,47±19,97 years old. Knowing that UTIs’ patients having ages ranged from 16 to 49 years old were most affected compared to other ages’ groups, with a frequency of 66,6 and 50% for female and male gender, respectively. The microbial strains represented by the bacteria group were predominant, ie (98,22%) followed by yeasts (1,78%), where Gram-negative bacilli showed (96,36%) of the uropathogenic agents, so (3,64%) were Gram-positive bacteria. The antibiotic resistance profile of isolated Enterobacteriaceae showed very high resistance rates for the species of Escherichia coli, Klebsiella spp, and Proteus spp to aminopenicillins, cephalosporins, and less against carbapenems and other drug groups. E. coli had presented the highest multidrug resistance followed by Klebsiella spp with a MAR index ranged from 0,53 to 0,82. Within this range, a total of 28 isolate (25 E. coli, 2 Klebsiella spp, and 1 Proteus mirabilis) had shown resistance against 9 to 14 out of the 17 tested antibiotics. The rate of ESBL-producing Enterobacteriaceae strains was 23,07 and 55,26% for inpatients and outpatients respectively, where E.coli was the most important ESBL producers out of all isolated strains. Conclusion: An alarming ESBLs rate for outpatients which is usually higher among inpatients with UTI, who receive several classes of antibiotics. Such condition should be considered as a major public health concern, and measures must be taken to establish the sources and drivers of this issue. Thus, the findings of this research pushes health sector stakeholders as well as scientific communities to act on reducing the transmission of the multidrug-resistant strains that threatens several classes of life-saving antibiotics.
