Background: Salmonella enteritidis causes infections in humans and animals. Antibiotics are used to eliminate bacterial infections, which become resistant to antibiotics after a while. This study aimed to isolate S. enteritidis from cattle feces samples and also to evaluate the frequency of genes associated with multi-drug resistance (MDR). Methods: One hundred ten fecal samples of cattle were collected from Jul to Dec, 2017 in Khuzestan Province, southern Iran. Bacterial culture and molecular methods were used to isolate and identify S. enteritidis. Disk diffusion method was used to assess antibiotic susceptibility. Then Polymerase chain reaction (PCR), assay was used for definitive diagnosis of S. enteritidis and resistance genes. Results: Overall, 101 (91.81%) samples were detected to be contaminated with Salmonella genus and 86 samples (85.14%) were identified as S. enteritidis. The highest and lowest antibiotic resistance were belonged to gentamicin (n=70, 81.39%), and tetracycline (n=6, 6.97%). Besides, 64 samples (74.42%) had 2-10 drugs resistance patterns. Moreover, the highest and the least resistance were related to blaIMP-1 (n=73, 84.88%) and tet(B) (n=49, 56.97%) genes respectively. Conclusion: The drug-induced genes in S. enteritidis have a high frequency. Therefore, antibiotic resistance and high MDR to antibiotics can be due to the incorrect use of antibiotics and the lack of health monitoring in Cattle farms.

The aim of this study was to determine antibiotic resistance patterns and the prevalence of uropathogenes causing urinary tract infections (UTIs) in patients hospitalized in January–June 2020 in central Poland. Antimicrobial susceptibility testing was performed using the disk-diffusion method. Escherichia coli (52.2%), Klebsiella pneumoniae (13.7%), Enterococcus faecalis (9.3%), E. faecium (6.2%), and Proteus mirabilis (4,3%) were most commonly isolated from urine samples. E. coli was significantly more frequent in women (58.6%) (p = 0.0089) and in the age group 0–18, while K. pneumoniae was more frequent in men (24.4%) (p = 0.0119) and in individuals aged 40–60 and >60. Gram-negative species showed resistance to ampicillin. K. pneumoniae were resistant to amoxicillin plus clavulanic acid (75.0%), piperacillin plus tazobactam (76.2%), cefotaxime (76.2%), cefuroxime (81.0%), ciprofloxacin (81.0%), and trimethoprim plus sulphamethoxazole (81.0%). Carbapenems were effective against all E. coli and P. mirabilis. Some K. pneumoniae (13.6%) produced metallo-β-lactamases (MBLs). E. coli (22.6%), K. pneumoniae (81.8%), and all E. faecium were multidrug-resistant (MDR). Some E. coli (26.2%), K. pneumoniae (63.6%), and P. mirabilis (14.3%) isolates produced extended-spectrum beta-lactamases (ESBL). Vancomycin-resistant E. faecium was also found. This study showed that the possibilities of UTIs therapy using available antibiotics become limited due to the increasing number of antibiotic-resistant uropathogens.

The presence of Salmonella spp. in marine animals is a consequence of contamination from terrestrial sources (human activities and animals). Bacteria present in marine environments, including Salmonella spp., can be antibiotic resistant or harbor resistance genes. In this study, Salmonella spp. detection was performed on 176 marine animals stranded in the Sicilian coasts (south Italy). Antibiotic susceptibility, by disk diffusion method and MIC determination, and antibiotic resistance genes, by molecular methods (PCR) of the Salmonella spp. strains, were evaluated. We isolated Salmonella spp. in three animals, though no pathological signs were detected. Our results showed a low prevalence of Salmonella spp. (1.7%) and a low incidence of phenotypic resistance in three Salmonella spp. strains isolated. Indeed, of the three strains, only Salmonella subsp. enterica serovar Typhimurium from S. coeruleoalba and M. mobular showed phenotypic resistance: the first to ampicillin, tetracycline, and sulphamethoxazole, while the latter only to sulphamethoxazole. However, all strains harbored resistance genes (blaTEM, blaOXA, tet(A), tet(D), tet(E), sulI, and sulII). Although the low prevalence of Salmonella spp. found in this study does not represent a relevant health issue, our data contribute to the collection of information on the spread of ARGs, elements involved in antibiotic resistance, now considered a zoonosis in a One Health approach.

Abstract This study aimed to investigate the prevalence, antibiogram of Pseudomonasaeruginosa (P.aeruginosa), and the distribution of virulence genes (oprL,exoS, phzM, and toxA) and the antibiotic-resistance genes (blaTEM, tetA, and blaCTX-M). A total of 285 fish (165 Oreochromisniloticus and 120 Clariasgariepinus) were collected randomly from private fish farms in Ismailia Governorate, Egypt. The collected specimens were examined bacteriologically. P. aeruginosa was isolated from 90 examined fish (31.57%), and the liver was the most prominent infected organ. The antibiogram of the isolated strains was determined using a disc diffusion method, where the tested strains exhibited multi-drug resistance (MDR) to amoxicillin, cefotaxime, tetracycline, and gentamicin. The PCR results revealed that all the examined strains harbored (oprL and toxA) virulence genes, while only 22.2% were positive for the phzM gene. On the contrary, none of the tested strains were positive for the exoS gene. Concerning the distribution of the antibiotic resistance genes, the examined strains harbored blaTEM, blaCTX-M, and tetA genes with a total prevalence of 83.3%, 77.7%, and 75.6%, respectively. Experimentally infected fish with P.aeruginosa displayed high mortalities in direct proportion to the encoded virulence genes and showed similar signs of septicemia found in the naturally infected one. In conclusion, P.aeruginosa is a major pathogen of O.niloticus and C.gariepinus.oprL and toxA genes are the most predominant virulence genes associated with P.aeruginosa infection. The blaCTX-M,blaTEM, and tetA genes are the main antibiotic-resistance genes that induce resistance patterns to cefotaxime, amoxicillin, and tetracycline, highlighting MDR P.aeruginosa strains of potential public health concern.

Resistance Patterns

Studies have shown that antibiotic resistance among wild animals is becoming a public health concern, owing to increased contact and co-habitation with domestic animals that, in turn, results in increased human contact, indirectly and directly. This type of farming practice intensifies the likelihood of antibiotic resistant traits in microorganisms transferring between ecosystems which are linked via various transfer vectors, such as rivers and birds. This study aimed to determine whether the practice of wildlife supplementary feeding could have an influence on the antibiotic resistance of the bacteria harboured by the supplementary fed wildlife, and thus play a potential role in the dissemination of antibiotic resistance throughout nature. Escherichia coli and Enterococcus were isolated from the faeces of various wildlife species from seven different farms across South Africa. The Kirby-Bauer disk diffusion method was used according to the Clinical and Laboratory Standards Institute 2018 guidelines. The E. coli (F: 57%; N = 75% susceptible) and Enterococcus (F: 67%; N = 78% susceptible) isolates from the supplementary fed (F) wildlife were in general, found to be more frequently resistant to the selection of antibiotics than from those which were not supplementary fed (N), particularly towards tetracycline (E. coli F: 56%; N: 71%/Enterococcus F: 53%; N: 89% susceptible), ampicillin (F: 82%; N = 95% susceptible) and sulphafurazole (F: 68%; N = 98% susceptible). Interestingly, high resistance towards streptomycin was observed in the bacteria from both the supplementary fed (7% susceptible) and non-supplementary fed (6% susceptible) wildlife isolates. No resistance was found towards chloramphenicol and ceftazidime.

Abstract Background Multidrug resistance is a serious problem in the treatment of urinary tract infections. Horizontal gene transfer, directed by strong selective pressure of antibiotics, has resulted in the widespread distribution of multiple antibiotic resistance genes. The dissemination of resistance genes is enhanced when they are trapped in integrons. Objectives To determine the prevalence of integrons among multidrug resistant Escherichia coli strains collected from regional hospitals and private clinical laboratories in Alborz province. Methods The susceptibility of 111 clinical Escherichia coli isolates was tested using a Kirby–Bauer disk diffusion method for common antibiotics. Isolates were screened for the production of extended spectrum β-lactamases (ESBLs) using a double disk synergy test. The existence of integrons was confirmed by amplification of the integrase gene and their class determined via analysis of PCR products by PCR-RFLP. Results Isolates showed the highest resistance to amoxicillin. Nitrofurantoin, amikacin, and ceftizoxime were the most effective antibiotics in vitro. Eighty-eight isolates of 111 (79%) were resistant to more than three unrelated drugs. We found 30% of the multidrug resistant isolates harbor integrons. Class 1 and 2 integrons were detected in 25 and 1 isolates, respectively. ESBL screening of strains showed 45 isolates (40%) were positive; 22% of the ESBL-positive isolates carried class 1 integrons and the frequency of MDR in ESBLpositive isolates was 93%. Conclusion The existence of integrons in only 29.5% of multidrug resistant isolates showed that besides integrons, antibiotic resistance genes were probably carried on other transferable elements lacking integrons, such as transposons or plasmids.

Objective:Failure to achieve success with penicillin treatment in some cases observed in the pediatric group and the decrease in macrolide activity have brought about the necessity of a new study aiming to differentiate bacteria at the species level in throat infections. Antibiotic resistance studies are of great importance for the treatment of bacterial infections in terms of public health and rational antibiotic use. For this purpose, we aimed to perform a species-level differentiation of streptococci isolated from the throat cultures of pediatric patients presenting to our hospital, to determine their antibiotic susceptibility, and to identify the macrolide resistance genes of mef(A), mef(E), erm(B) and erm(TR) in patients with Streptococcus pyogenes. The study included 51 samples taken from pediatric cases presenting with a sore throat as the patient group and 36 samples from children without this complaint as the control group. Material and Method: The throat culture samples taken from 51 children presenting to the hospital with the complaint of sore throat were evaluated in the laboratory, and streptococcus was diagnosed using tests; gram staining, catalase and PYR, and the susceptibility profile was determined with the Kirby-Bauer disk-diffusion method. Bacteria were identified at the species level according to 16srRNA sequences, and possible macrolide resistance genes of mef(A), mef(E), erm(B) and erm(TR) were determined by PCR in species detected to have S. pyogenes. Results: Our antibiotic susceptibility results were consistent with the general results reported in Turkey. The sequence analysis of bacteria was performed according to 16srRNA sequences, and S. pyogenes, Streptococcus pneumoniae, Streptococcus anginosus, Streptococcus agalactiae, and Streptococcus dysgalactiae were isolated. In patients with S. pyogenes, the genetic determinants of macrolide resistance, mef(A), mef(E), erm(B) and erm(TR), were investigated with the PCR method using primers specific to each gene. Different levels of expression were observed in five patients. Macrolide resistance in S. pyogenes, which is reported at various percentages in the world, was found to be 9.8% in our study. Discussion: The results of our study show that penicillin resistance genes were found in five of the patients evaluated. When the anamnesis of these patients was examined, it was determined that there were patients that frequently presented to the hospital with throat infections and experienced re-infection within a few weeks after receiving treatment. The common discourse of clinicians is that there may be an unknown resistance development. Therefore, our research should be supported by new hypotheses and studies that are open to development.

Background: Paper banknotes would be a vector for transmission of pathogenic microorganisms through handling. Objective: This study aimed to determine bacterial contamination of Iranian paper currencies in circulation and their antibiotic resistance patterns. Materials and Methods: In this study, 337 currency notes of different value were collected from markets, shops, restaurants, bus stations and banks in Kashan, Iran during April 2015 to March 2016. The currency notes transferred to microbiology laboratory and were tested for bacterial contamination using standard microbiological methods. Antibiotic resistance patterns of isolated bacteria were determined by disk diffusion method according to the Clinical and Laboratory Standards Institute (CLSI) standards. The results and data were analyzed using descriptive statistics. Results: Of 337 currency notes, 262 (77.7%) were identified with bacterial contamination. Bacteria isolated from currency notes were as follows: Bacillus spp 113 (43.1%), coagulase-negative staphylococci 99 (37.7%), Escherichia coli 20 (7.6%), Enterococci species 14 (5.3%), Staphylococcus aureus 8 (3.1%), Klebsiella spp 4 (1.5%), Shigella species 2 (0.8%), and Pseudomonas species 2 (0.8%). The most and least contaminated currency notes were 50000 and 500 Rials, respectively. The highest resistance rates in gram-negative rods were against nalidixic acid, and ampicillin. However, the highest resistance rates in S. aureus, coagulase-negative staphylococci and Enterococci species were against ampicillin, erythromycin and tetracycline. Conclusion: Our study revealed that the bacterial contamination among Iranian paper currency in circulation especially those obtained from certain sources including shops and bus stations is high and in most cases these bacterial isolates are antibiotic-resistant strains.

Background. Diarrheagenic E. coli (DEC) is an etiological agent of childhood diarrhea. Resistance against commonly used drugs in the empirical treatment of enteric infections has increased among DEC. Relationship between antibiotic resistance and biofilm formation in microorganisms have been widely reported. This study was aimed to determine the antibiotic resistance and biofilm production pattern among DEC pathotypes isolated from stools of children aged 0–5 years with acute diarrheal disease in Abakaliki, Nigeria. Materials and methods. Diarrheal stool samples were obtained from 60 children and E. coli were isolated and identified using standard guidelines provided for laboratory diagnosis of enteric pathogens. Molecular identification was done by amplification of E. coli universal stress protein A (uspA) using polymerase chain reaction (PCR) method. Detection of virulent genes of DEC pathotypes was performed in a group of multiplex PCR using their specific primers. Kirby–Bauer disk diffusion method was used to determine the antibiotic susceptibility patterns of the isolates while biofilms production was detected by thiazolyl blue tetrazolium bromide dye in a 96-well plate. Results. DEC was isolated in 40 stools among which EIEC [40% (n = 16)] was commonly detected followed by ETEC [30% (n = 12)], EAEC [20% (n = 8)] and typical EPEC [10% (n = 4)]. Half of EAEC showed the highest multidrug resistance against ampicillin, cefoxitin, ciprofloxacin, levofloxacin, and tetracycline with the strongest biofilm production followed by all the EPEC which were resistant to ampicillin, ciprofloxacin, levofloxacin, and tetracycline with moderate biofilm production. All the LT-ETEC exhibited the least resistance to ampicillin and tetracycline with the weakest biofilm production. Conclusion. High frequency of the EIEC pathotype suggests its role as the primary etiological agent of diarrhea in children. Correlation between high drug resistance and biofilm production among the pathotype may indicate that biofilms may provide compatible uptake of resistance genes.

Antibiotic Resistance Patterns

Antibiotic resistant E. coli are prevalent in Bangladesh. The indiscriminate use of antimicrobials and ready availability of over the counter drugs are responsible for this. This study was conducted to investigate the susceptibility of clinical Escherichia coli to the antibiotics Imipenem, Ceftriaxone, Ceftazidime and Azithromycin. Kirby-Bauer disk diffusion method was used to determine sensitivity to antimicrobials. Agar based assay was employed for the detection of efflux pumps. PCR was used amplify antibiotic resistance genes.All isolates were resistant to Ceftriaxone whereas most were sensitive to Imipenem. The MICs of Ceftazidime and Azithromycin ranged between 128 μg/ml and 256 μg/ml. The prevalence of ²-lactamase producers was 57.89 % with 36.84 % of the isolates exhibiting ESBL activity. No specific correlation could be found between plasmid sizes and antibiotic resistance patterns. Efflux pump was found to be involved in Azithromycin resistance in 63.15% of the isolates. The gene for phosphotransferase, mph(A) was the most common among the macrolide modifying genes, being present in 73.68% (14/19) of the isolates followed by both erm(A) anderm(C) esterases each present in 10.53% (2/19) isolates. This study concluded that clinical isolates of E. coli in Bangladesh could be resistant to multiple classes of antibiotics through different mechanisms of resistance.

Meats are important potential sources of foodborne pathogens including Escherichia coli. This study was conducted to determine the prevalence and antimicrobial resistance of Escherichia coli isolated from meats in the Tamale metropolis of Ghana. Isolation of Escherichia coli was done using the procedure according to the USA-FDA Bacteriological Analytical Manual. Antibiotic resistance patterns in the Escherichia coli isolates were determined by the Kirby-Bauer disk diffusion method against 8 antibiotics. The overall prevalence of Escherichia coli in the meat samples was 84.00% (189/225). Mutton (88.89%), guinea fowl (88.89%), beef (86.67%), local chicken (80.00%), and chevon (75.56%) were contaminated by Escherichia coli. The average coliform count was 4.22 cfu/cm2 and was highest in guinea fowl (4.94 log cfu/cm2) and lowest in local chicken (3.23 log cfu/cm2). The Escherichia coli isolates were highly resistant to erythromycin (85.00%), tetracycline (73.33%), and ampicillin (71.67%). The multiple antibiotic resistance (MAR) index ranged from 0.13 to 1. The Escherichia coli isolates exhibited 23 antimicrobial resistance patterns with resistant pattern TeAmpE (tetracycline-ampicillin-erythromycin) being the most common. Multidrug resistance was 68.33% (41/60) among the Escherichia coli isolates. The results showed that Escherichia coli was commonly present in the various meat types and exhibited multidrug resistances, necessitating efficient antibiotic stewardship guidelines to streamline their use in the production industry.
