, which determine their pathogenic nature and allow survival in extreme conditions. Comparison of the antibiotic resistance genes found in the microorganisms living in humans and animals indicates that many of them are identical and only few are present exclusively in bacteria that live in humans or certain species of animals [51]. In recent decades, the number of companion animals, i. e. dogs, cats or horses, has increased significantly. The social function of these animals has also changed and they

Anaerobic Bacteroides species are dominant microbiota of the digestive tract of mammals. Along with other symbiotic bacteria located in the gastrointestinal tract, they contribute to the proper functioning of the organism. Some Bacteroides species are highly pathogenic. Virulence of these bacteria is related to their polysaccharide capsule, lipopolysaccharide and a variety of enzymes and enterotoxin. In recent years, an increase of antibiotic resistance in Bacteroides spp. has been noted

This work aims to provide an insight into staphylococcal cassette chromosome mec elements and antibiotic resistance in clinical isolates of Staphylococcus epidermidis. The dominating type was SCCmec – IV. Fifteen isolates were assigned to SCCmec type III, two isolates to SCCmec type II. Most isolates were resistant to at least three of the non-β-lactam antibiotics tested. None of the strains exhibited resistance to new generation antibiotics, such as daptomycin and linezolid. Also

The characteristics of Pseudomonas genus
The genus Pseudomonas was first described by Migula in 1894 in just two concise sentences: “Cells with polar organs of motility. Formation of spores occurs in some species, but it is rare” [61

To understand the molecular epidemiology and antibiotic resistance of air and clinical isolates of Acinetobacter baumannii, the intensive care unit settings of a hospital in Northern China were surveyed in 2014. Twenty non-duplicate A. baumannii isolates were obtained from patients and five isolates of airborne A. baumannii were obtained from the wards’ corridors. Pulsed field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) were used to analyze the homology relationships of

Six strains showed multiple antibiotic resistance patterns and in addition, vanA and several virulence genes were detected in many strains. Only E. faecalis MBE1-9 showed tyrosine decarboxylase activity and tdc gene was detected only in this strain.

Strains suspected of belonging to SAG were re-identified using an automated biochemical approach (Vitek2) and MALDI-TOF MS. We performed first analysis of antibiotic resistance among SAG strains isolated in Poland using automated methods (Vitek2), disk

Enterococcus faecalis and Enterococcus faecium are among the main agents associated with nosocomial infections with high mortality in immunocompromised patients. Antibiotic resistance, especially against gentamicin and vancomycin among Enterococci, is a risk factor that could increase the morbidity and mortality rate. 179 Enterococci isolates from burn patients were included in this study. Antibiotic susceptibility testing was done using the disk diffusion test and minimum inhibitory

Escherichia coli is one of the most frequent causes of urinary tract infections. Efflux system overexpression is reported to contribute to E. coli resistance to several antibiotics. Our aim in this study was to investigate the relation between antibiotic resistance and the expression of the efflux pump genes acrA and mdfA in E. coli by real-time reverse transcription-PCR. We tested the in vitro susceptibilities to 12 antibiotics in 28 clinical isolates of E. coli obtained from urine

Several virulence and antibiotic resistance genes have been identified and isolated from this group, which if present in their mobile genetic elements, may be horizontally transferred to other naive environmental bacteria posing threat to the society. The extensive and indiscriminate use of antibiotics has given rise to many resistant varieties of bacteria. Multidrug resistance genes, such as NDM1, have been identified in this group

This speech turned out prophetic, and currently, over 90 years after discovering penicillin, antibiotic resistance is spreading rapidly worldwide, causing a crisis to public health. The following are the well-known causes of the spread of antibiotic resistance: overuse of antibiotics in agriculture, veterinary, and human medicine; use of antibiotics as growth promoters; illegal and uncontrolled antibiotic markets; and use of antibiotics without taking a

metal contamination could directly or indirectly impact the maintenance and proliferation of antibiotic resistance (Summers 2002). Several studies reported the co-occurrence of heavy metal and antibiotic resistance. It has been proven that heavy metals in environmental reservoirs, water, wastewater, and soil, may contribute to the selection of antibiotic-resistant strains through co-resistance and cross-resistance mechanisms (Nguyen et al. 2019). It is important to underline that co-resistance

Overuse and imprudent use of antimicrobial agents are recognized as one of the leading causes of antibiotic resistance. The aim of this study was to analyze the attitudesof Polish physicians practicing at the community level towards antibiotics and antimicrobial resistance. The majority of physicians taking part in the survey believed that Polish people overuse antibiotics (98%). Most
