Skin Samples

The present study aimed to determine the prevalence of Staphylococcus species, which pose risks for public health, by evaluating skin samples collected from dogs in an animal shelter in Timisoara. Skin samples were taken from 78 dogs, which were either clinically healthy or suffering from dermatological conditions. Staphylococcus spp. was isolated and recognized based on conventional methods based on colony appearance, microscopic morphology, sugar fermentation, and coagulase activity. Following biochemical analysis, Staphylococcus isolates were subject to PCR tests to detect sa-f and sa-r genes to confirm the isolates to genus level. The typical colonies were identified to species level using biochemical methods, namely the VITEK®2 ID-GP64 identification card (bioMerieux, France). The phenotypic antimicrobial resistance profiling was performed using the VITEK®2 AST GP Gram-positive specific bacteria card (bioMerieux, France). Forty-three samples were confirmed as positive for Staphylococcus spp. Staphylococcus isolates were classified into the following categories: S. aureus, S. pseudintermedius, S. intermedius, S. epidermitis, S. haemolyticus, and S. hyicus. Eight (18.60%, 8/43) out of all the samples harbored the mecA gene, highlighting the distribution among isolated staphylococcal species: Staphylococcus pseudintermedius (4/43, 9.30%), Staphylococcus intermedius (1/43, 2.32%) and Staphylococcus aureus (3/43, 9.30%), respectively. The phenomenon of resistance was present, to the following antimicrobial agents: erythromycin (38/43, 88.37%), benzylpenicillin, kanamycin, and tetracycline with 37 strains (37/43, 86.04%), gentamycin (30/43, 69.76%), chloramphenicol (29/43, 67.44%), trimethoprim/sulfamethoxazole (27/43, 62.79%), ampicillin (26/43, 60,46%), rifampicin (25/43, 58,13%), imipenem (14/43, 32,55%), nitrofurantoin (11/43, 25.58%), oxacillin (8/43, 18.60%), vancomycin (4/43, 9.30%) and clindamycin (3/43, 6.97%), respectively. The presence of multidrug-resistant zoonotic staphylococci in clinically healthy dogs and dogs with skin lesions is an animal health and human health concern.

The presence of Staphylococcus spp. has increasingly been reported in food products and poses a public health threat. The aim of this study was to determine the diversity of Staphylococcus spp. and the antibiotic resistance profiles of isolates obtained from freshly harvested and packed ready-to-eat mushrooms (n=432) and handlers’ hands (n=150). A total of 56 Staphylococcus isolates [46.4% (n=26) from hands and 53.6% (n=30) from mushrooms] were recovered belonging to 10 species. Staphylococcus succinus isolates (n=21) were the most prevalent, of which 52.4% came from mushrooms and 47.6% from hands. This was followed by S. equorum isolates [n=12; 91.7% (n=11) from mushrooms and 8.3% (n=1) from hands] and S. saprophyticus [n=9; 66.7% (n=6) from mushrooms and 33.3% (n=3) from hands]. Six isolates that were characterised as multidrug resistant were isolated from hands of handlers. Most (83.9%; n=47) of the 56 isolates were resistant to penicillin [53.2% (n=25) from mushrooms and 46.8% (n=22) from hands] and 14.3% (n=8) were resistant to cephalosporin classes [25% (n=2) from mushrooms and 75% (n=6) from hands], both of which are used to treat staphylococcal infections. Antibiotic resistance genes blaZ [25.0% (n=14) of all isolates of which 71.4% (n=10) were from hands and 28.57% (n=4) from mushrooms], tetL and tetK [both 1.8% (n=1) from hands], mecA [5.4% (n=3) from hands] and ermA [1.8% (n=1) from mushrooms] were detected from the 56 isolates. Only two (25.0%) of the eight methicillin-resistant staphylococci harboured the mecA gene, while only 11 (23%) of the 47 penicillin-resistant isolates harboured the blaZ gene [36.4% (n=4) from mushrooms and 63.6% (n=7) from hands]. Our results demonstrate that food handlers and harvested and packed ready-to-eat mushrooms could be a source of diverse Staphylococcus spp. that exhibit antimicrobial resistance. Clinically relevant S. aureus was only detected on one handler’s hand; however, the isolate was not multidrug resistant. The presence of diverse Staphylococcus spp. on mushrooms and the hands of handlers is a potential public health concern due to their potential to cause opportunistic infections.

Background. Staphylocci are the leading pus-forming Gram-positive bacteria in the childrens hospitals. The prevalence of the antibiotic resistant strains among them limits therapeutic effects of infections in children. Aim. The research is aimed at characterizing the species of staphylococcus, which are isolated from the different clinical specimens of the patients at the clinics of Saint Petersburg State Pediatric Medical University in 2019, and analysis of their susceptibility to antimicrobial agents. Materials and metods. According to the clinical recommendations of 2018, susceptibility to antimicrobial drugs (AMD) was revealed in 860 strains of staphylococci determined by the disc diffusion method, which were identified by the automated analyser Vitek-2 compact. Results. Six species of staphylococci were represented at the hospital departments, among which Staphylococcus epidermidis prevailed in the departments of the neonate pathology department and intensive care units (63.0% and 46.2% respectively), Staphylococcus aureus is commonly found at the departments of surgery and the departments of the therapeutic profiles (61.7% and 46.2% respectively). More than a half of the staphylococci strains (63.0%) were resistant to at least one of the antimicrobial drugs. Vancomycin and line solid showed the highest activity to these staphylococci. High specific weight of multidrug resistant (MDR) bacteria (37.8%) and extensively drug resistant (XDR) strains of the phenotype (33.0%) was revealed. The level of antibiotic resistant strains was the highest in Staphylococcus haemolyticus (98.1%) and S. epidermidis (82.0%), while the specific weight of the resistant ones, MDR and XDR strains was extremely low among S. aureus (16.2%, 1.5% and 0.4 respectively), as well as in methicillin-resistant isolates (0.8%). Conclusions. A great variety of antibiotic resistance was revealed among the staphylococci. The prevalence of these strains in the pediatric hospitals requires constant local monitoring of the antibiotic resistant staphylococci.

Abstract Many pathogenic strains have acquired multidrug-resistant patterns in recent a year, which poses a major public health concern. The growing need for effective antimicrobial agents as novel therapies against multidrug-resistant pathogens has drawn scientist attention toward nanotechnology. Silver nanoparticles are considered capable of killing multidrug-resistant isolates due to their oligo-dynamic effect on microorganisms. In this research study NPs were synthesized using the gram-positive bacteria Lactobacillus bulgaricus and its activity against selected pathogenic strains. Lactobacillus bulgaricus pure cultures were isolated from raw milk and grown in “De Man, Rogasa, and Sharp” broth for synthesis of nanoparticles. Lactobacillus bulgaricus culture was centrifuged and Cell- free supernatant of it was employed with aqueous silvery ions and evaluated their antibacterial activities against bacterial strains i.e. Staphylococcus aureus, Staphylococcus epidermidis and Salmonella typhi using agar well diffusion assay. Antibiotic profiling against selected pathogenic strains were also conducted using disc diffusion method. The synthesis and characterization of silver nanoparticles were monitored primarily by the conversion of the pale-yellow color of the mixture into a dark-brown color and via ultraviolet-visible absorption spectroscopy and Scanning electron microscopy respectively. The result showed that that AgNPs with size (30.65-100 nm) obtained from Lactobacillus bulgaricus were found to exhibit antibacterial activities against selected bacterial strains. Taken together, these findings suggest that Lactobacillus bulgaricus has great potential for the production of AgNPs with antibacterial activities and highly effective in comparison to tested antibiotics.

Abstract Background Antimicrobial resistance (AMR) in foodborne pathogens of animal origin, including nontyphoidal Salmonella (NTS), is a public health concern. Pennsylvania conducts integrated surveillance for AMR in NTS from human and animal sources in collaboration with the FDA and CDC National Antimicrobial Resistant Monitoring System (NARMS). Methods We reviewed pulsed-field gel electrophoresis (PFGE), antimicrobial susceptibility (SST) and whole-genome sequencing (WGS) data for isolates from animal and food sources, including 96 NTS from 2,520 meat samples (poultry, ground beef and pork chops) purchased during 2015–2017 from randomly selected retail outlets in Pennsylvania. SST to 15 antimicrobial agents was done on 109 NTS clinical isolates that had similar PFGE patterns to meat isolates. SST and WGS were used to characterize all isolates from meat and two clinical isolates from 2017. Results 28 (29.2%) and 17 (17.7%) NTS isolated from meat sources were resistant to ≥3 and ≥5 antibiotics classes, respectively. Resistance to ceftriaxone rose from 12% (3/25) in 2015 to 27% (10/37) in 2016 and resistance to amoxicillin/clavulanate also increased. Plasmid-mediated bla CMY-2 β-lactam resistance genes that hydrolyze extended-spectrum cephalosporins (ESC) increased from 12% in 2015 (3/25) to 18.9% (7/37) in 2016. Four blaCTX-M-65 genes that confer resistance to extended-spectrum β-lactamases (ESBLs) were identified in 2016 (n = 3) and 2017. Of the 109 clinical isolates, 25.7% demonstrated resistance to ≥3 and 11% to ≥5 antibiotics classes, respectively. No clinical isolates were resistant to ceftriaxone in 2015, 12.5% (6/48) and 24.3% (9/37) were resistant in 2016 and 2017, respectively. Resistance to amoxicillin/clavulanate was demonstrated in 8.3% (4/48) of isolates in 2016 (figure). Two clinical isolates carried blaCTX-M-65 ESB Ls genes and were resistant to eight antimicrobial agents (ACSSuTCxNalCot. Phenotype). Conclusion NTS (≥25%) from animal and human sources were multidrug-resistant and harbored CMY-2 and CTX-M-65 genes. Dissemination of genes that confer resistance to ESBLs and ESCs in NTS undermines recommended treatment for severe infections and underscores the need for One-Health surveillance and antimicrobial stewardship efforts.

For almost a decade, the number of Salmonella enterica subspecies enterica serovar Infantis-positive broiler flocks has been steadily increasing in Slovenia, doubling the number of positive holdings in only a few years. Since multidrug resistant S. Infantis isolates are highly prevalent in the broiler meat industry and may represent a public health concern through the food chain, we aimed to investigate the antimicrobial susceptibility, genetic diversity, and biofilm-forming ability of S. Infantis from Slovenian broiler flocks. A total of 87 S. Infantis strains isolated from broiler faeces in the period between 2007 and 2013 were studied. The samples originated from 41 farms which were subcontractors of three major food business operators and from two autonomously operating holdings (farms). Isolates were phenotypically tested for their susceptibility to 14 antimicrobials from nine classes by determining the minimum inhibitory concentration with the microdilution method. Only 8% of the isolates were susceptible to all of the antimicrobial agents tested, while 88.5% of the isolates were multidrug resistant, with the most common resistance pattern CipNxSSuT (65.5%) followed by CipNxSuT (17.2%). Pulsed-field gel electrophoresis (PFGE) divided the strains into five clusters (A-E) comprising 16 distinct XbaI PFGE profiles. Sixty-five out of 87 isolates were grouped in clusters A and B, with the predominant PFGE profiles A1 and B1 encompassing 33 and 28 isolates, respectively. A vast majority of the isolates (75/87) showed >90% PFGE profile similarity. The biofilm-forming capacity of the tested isolates, determined with crystal violet assay in polystyrene microwell plates, was generally weak. The average biofilm formation for persistent strains was higher than for presumably nonpersistent strains; however, the difference was not significant. It seems that S. Infantis persistence on broiler farms is more related to its widespread occurrence in the broiler production chain and ineffective disinfection protocols than to its ability to form biofilm.

Abstract The presence of emerging contaminants (ECs) in the environment has been consistently recognized as a worldwide concern. ECs may be defined as chemicals or materials found in the environment at trace concentrations with potential, perceived, or real risk to the “One Health” trilogy (environment, human, and animal health). The main concern regarding pharmaceuticals and in particular antibiotics is the widespread dissemination of antimicrobial resistance. Nevertheless, non-antimicrobials also interact with microorganisms in both bulk phase and in biofilms. In fact, drugs not developed for antimicrobial chemotherapy can exert an antimicrobial action and, therefore, a selective pressure on microorganisms. This review aims to provide answers to questions typically ignored in epidemiological and environmental monitoring studies with a focus on water systems, particularly drinking water (DW): Do ECs exposure changes the behavior of environmental microorganisms? May non-antibiotic ECs affect tolerance to antimicrobials? Do ECs interfere with biofilm function? Are ECs-induced changes in microbial behavior of public health concern? Nowadays, the answers to these questions are still very limited. However, this study demonstrates that some ECs have significant effects in microbial behavior. The most studied ECs are pharmaceuticals, particularly antibiotics, carbamazepine and diclofenac. The pressure caused by antibiotic and other antimicrobial agents on the acquisition and spread of antibiotic resistance seems to be unquestionable. However, regarding the effects of ECs on the development and behavior of biofilms, the conclusions of different studies are still controversial. The dissimilar findings propose that standardized tests are needed for an accurate assessment on the effects of ECs in the microbiome of water systems. The variability of experimental conditions, combined with the presence of mixtures of ECs as well as the lack of information about the effects of non-pharmaceutical ECs constitute the main challenge to be overcome in order to improve ECs prioritization.

ABSTRACT: This study focused on counting Staphylococcus spp. in curd cheeses “requeijão” and “especialidade láctea type requeijão” sold in Brazil, assessing the presence of mecA gene in obtained isolates and establishing antimicrobial resistance profile of the mecA gene positive isolates. To this, a set of 200 samples of these dairy products were evaluated. Low counts of Staphylococcus spp. were observed in these dairy products. All the isolates were determined as coagulase-negative strains using coagulase test and PCR. However, two isolates (3.70%) were carriers of mecA gene and they can be considered as risk for public health. These isolates presented resistance to penicillin, oxacillin and erythromycin. In conclusion, low counts of Staphylococcus were detected in curd cheese “requeijão” and “especialidade láctea type requeijão” sold in Brazil. However, coagulase-negative methicillin-resistant Staphylococcus spp. was detected in these dairy products. This is the first report of the detection of methicillin-resistant Staphylococcus spp. in heat-treated dairy products in Brazil. Results served as a warning to public sanitary authorities to control multidrug-resistant strains in veterinary and human medicine.

Aim. To study the nature of microbiota and estimating the susceptibility to antibiotics and bacteriophages of conditionally pathogenic microflora of the nasopharynx in children-pneumococcal carriers with recurrent respiratory infections. Methods. Researching microflora was conducted in 182 pneumococcal carriers receiving help in Kazan Scientific and Research Institute of Epidemiology and Microbiology. Microbial identification, testing of susceptibility to antibiotics and bacteriophages was carried out following the regulatory documentation. Bacterial isolates were confirmed by mass spectrometry. The phage titer was determined by the method of agar layers according to Grazia. Results. Nasopharyngeal S. pneumoniae species was presented by Staphylococcus spp., Moraxella spp., Haemophilus spp., Corynebacterium spp., Klebsiella spp and Candida spp. The antimicrobial resistance profiles of Streptococcus pneumoniae: resistant to oxacillin was detected in 20.7% of strains, to erythromycin in 45.9%, to clindamycin in 20%, to trimethoprim-sulfamethoxazole in 18.4%. 19.6% of isolates were multidrug-resistant (MDR, resistant to 3 or more antimicrobial agents). Phage susceptibility test of S. pneumoniaе showed that 97.2% of isolates were resistant to streptococcal bacteriophage, 75% to pyobacteriophage. All antibiotic-resistant strains remained susceptible to Streptococcus phages. The phage titer of Klebsiella in agreement with Grazia method of Kl. pneumoniae ranged from 9106 to 5105 PFU/mL. The ranking results of activities of antistaphylococcal antibiotics (effectiveness descending): fusidic acid mupirocin chloramphenicol cyprofloxacin erythromycin. Conclusion. Nasopharyngeal microbiota of pneumococci carriers children is represented by a variable polymicrobial association; nasopharyngeal strains are effectively lysed by bacteriophages; mono- and polyvalent bacteriophages can be used as an alternative to antibacterial treatment in Streptococcus pneumoniae carriers children with recurrent respiratory infections.

Salmonella are the major pathogenic bacteria in humans as well as in animals. Salmonella species are leading causes of acute gastroenteritis in several countries and salmonellosis remains an important public health problem worldwide, particularly in the developing countries. Isolation of Salmonella from a wide range of sources suggests that Salmonella is widespread in food animals and meat products and underlines the necessity for a joint and coordinated surveillance and monitoring programs for salmonellosis and other major food borne zoonotic diseases. Food animals harbor a wide range of Salmonella and so act as sources of contamination, which is of paramount epidemiological importance in non-typhoid human salmonellosis. Salmonellosis is more aggravated by the ever increasing rate of antimicrobial resistance strains in food animals. The high prevalence and dissemination of multidrug resistant (MDR) Salmonella have become a growing public health concern. Multidrug resistant (MDR) strains of Salmonella are now encountered frequently and the rates of multidrug resistance have increased considerably in recent years. Food animal consumption is a potential cause for antimicrobial resistant Salmonella illnesses besides, the common factors such as overcrowding, poverty, inadequate sanitary conditions, and poor personal hygiene. Practicing good sanitary measures, extensive education programs for proper hygiene and improvement of managements are solutions to eliminate the high bacteriological load as well as prevalence of Salmonella in cattle carcass. Furthermore, restricting the use of antimicrobial agents in food animals, designation of multidrug-resistant Salmonella as an adulterant in ground beef, improving the mechanisms for product trace-back investigations and wise and discriminate use of antimicrobials should be practiced to combat the ever increasing situation of antimicrobial resistance. So, this review used for updating information on their prevalence and resistance patterns is very important to suggest the acceptance of the carcass in relation to the standards and for proper selection and use of antimicrobial agents in a setting.
