Characterization of Faecal Enterococci from Wild Birds in Turkey and Its Importance in Antimicrobial Resistance

ΔΕΝ ΔΙΑΤΙΘΕΤΑΙ ΠΕΡΙΛΗΨΗThis research aimed to investigate the diversity of faecal enterococci isolated from wild birds, to detecttheir antibiotic resistance patterns and to determine their distribution of genes related to vancomycin resistance. Additionally, to investigate their virulence factors that are important in the development of the disease. One hundred seven cloacal/rectal samples were inoculated onto Enterococcus Agar, and presumptive colonies were identified and confirmed by PCR. Multiplex PCR assays were used to screen vanA, vanB, vanC1 and vanC2/3. The virulence-related genes; ace, gelE, efa and agg were determined by PCR. Among the 103 enterococci, 62 E.faecalis, 23 E.faecium 3 E.gallinarum, 2 E.durans, 1 E.casseliflavus and 12 Enterococcus spp. were identified. Of the 103 enterococci, 26 were found to be resistant against to three or more antibiotics. The highest percentages were detected for chloramphenicol (52%), tetracycline (33%) and erythromycin (30%). Two E.gallinarum isolates were harboring three virulence factors, and one isolate was carrying a single virulence factor. There is no virulence factor in the E.casseliflavus isolate. Also, vanA and vanB genes were not found. Forty-two of 103 enterococci were harboring virulence factors, more frequently in E.faecalis. Forty-two enterococci carried efa A, 31 isolates carried gel E, and ace was found in 18 isolates. Virulence gene agg was not detected. When the results of the study were evaluated in general, multiple drug resistance was described as 25%. Considering the risk of polluting the water resources of wild animals, it is suggested that the continuity of this type of epidemiological study in wildlife animals is necessary. In conclusion, the wild birds may act as substantial reservoirs carrying antimicrobial resistance among enterococci and estimate the potential risk for man, pets and farm animals

Isolates from Raw Chicken Meats

Globally, the spread of antibiotic resistance via chicken meat consumption cause serious public health concerns. With this respect, the current study aimed to investigate the prevalence of thermophilic Campylobacter species isolated from raw meat chicken samples and their genetic determinants of resistance to various classes of antibiotics. A total of 540 chicken raw meat samples collected from various supermarkets and slaughterhouses in Istanbul, Turkey were analyzed according to EN ISO 10272-1:2006 standard procedure. For Identification of the genus and species of the isolates, multiplex PCR assay was held. Minimum inhibitory concentrations of the antimicrobial agents (nalidixic acid, ciprofloxacin, tetracycline, gentamicin, kanamycin, and erythromycin) were initially determined using the broth microdilution method. In addition, the genetic determinants of antimicrobial resistance were investigated by PCR assays. In total, 357 (66.1%) Campylobacter isolates were obtained including 268 Campylobacter jejuni and 89 Campylobacter coll. Resistance to quinolones (nalidixic acid and ciprofloxacin) was the most common in all strains (80.1%), followed by resistance to tetracycline's (703%). The lowest resistance was determined as resistance to kanamycin (4.2%). Gentamicin and erythromycin resistance was not observed in this study. Only five C coil isolate (1.4%) was classified as multidrug resistant. On the basis of these data, execute widely presence of antimicrobial resistance to quinolones and tetracycline's in C. jejuni and C. coil isolates from chicken raw meat samples and emphasizes that further multidisciplinary studies and novel strategies in the concept of 'One Health' are needed

Dermatophytosis caused by a Chrysosporium species in two cats in Turkey: a case report

Dermatophytes are infectious agents and can cause the zoonotic disease dermatophytosis in animals and humans. Keratinophilic fungi and especially dermatophytes can be detected on the hair coat and skin of cats. The aim of this report is to present a rarely seen dermatophytic skin disease in cats. Two Persian cats, living in the same house, were found to be positive for Chyrososporium spp. using mycological culture. At that time the owner of the cats was undergoing chemotherapy for a mammary tumour. This treatment led to low immunity, intensive pruritus and also to scaling on the inside of her arms. Chrysosporium spp. were also detected in the cats' owner. Antifungal therapy was applied with fluconazole to both cats. Because of widespread lesions and alopecia, intravenous fluconazole was administered with a saline solution. The lesions improved inside a six week period after fluconazole therapy and no adverse effects were observed

Antimicrobial effects of curcumin against L. monocytogenes, S. aureus, S. Typhimurium and E. coli O157:H7 pathogens in minced meat

The aim of this study was to determine the antimicrobial efficacy of curcumin, one of the active components of the Curcuma longa (turmeric) plant, against food pathogens in a minced meat medium. Salmonella Typhimurium ATCC 14028, Listeria monocytogenes ATCC 7644, Escherichia coli O157:H7 ATCC 33150 and S. aureus ATCC 25923 strains were used as food pathogens. Minimum inhibitory concentrations (MICs) were determined using the macrodilution method. MIC values for curcumin were found to be 125 mu g/ml for L. monocytogenes and S. aureus, and 250 mu g/ml for S. Typhimurium and E. coli O157: H7. Food pathogens were added to the minced meat at 104 CFU/g (including the control group) and curcumin at doses of 0.5%, 1% and 2% (except the control). The curcumin-supplemented minced meat and control were analysed 0-7 days later. At the end of seven days, it was seen that the 2% dose of curcumin had lowered L. monocytogenes and S. aureus counts by approximately 3 log CFU/g, and E. coli O157: H7 and S. Typhimurium counts by approximately 2 log CFU/g; the 1% dose had lowered L. monocytogenes, S. aureus, E. coli O157: H7 and S. Typhimurium counts by approximately 2 log CFU/g; and that the 0.5% curcumin dose had lowered L. monocytogenes and S. aureus count by approximately 2 log CFU/g, and E. coli O157: H7 and S. Typhimurium count by approximately 1 log CFU/g. Changes in bacterial counts were found to be statistically significant (P = 0.05). It was observed that antibacterial effect increased in direct proportion to dose, while sensory approval decreased. In this study, 0.5% and 1% curcumin doses were determined to be sensorily acceptable. It was concluded that, in view of the scientific benefits and antimicrobial efficacy of curcumin, it may be used instead of, or in smaller doses together with preservative additives in foods where colour change is not important

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

Aims The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. Methods and results Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (inhospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, prehospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. Conclusion The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality
