ANTIBIOTIC RESISTANCE OF BACTERIA A GROWING THREAT FOR ANIMALS AND PUBLIC HEALTH

, 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

BACTEROIDES SPP. – CLINICAL SIGNIFICANCE, ANTIBIOTIC RESISTANCE AND IDENTIFICATION METHODS

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

Characterization of Staphylococcal Cassette Chromosome mec (SCCmec) in Methicillin-Resistant Staphylococcus epidermidis Strains Isolated from Biomaterial-Associated Infections and their Antibiotic Resistance Patterns

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 purpose of this review is to provide an overview of current knowledge about the mechanism of antibiotic resistance in bacteria on the example of the Pseudomonas species, antimicrobial activity as well as EOs mode of action and their constituents. 2. 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

The presence of numerous UPEC cells in the urine (≥ 105 CFU/ml) without the clinical symptoms is called asymptomatic bacteriuria (ABU) and in healthy non-pregnant women is not treated in 20–80% of cases (Schneeberger et al. 2014).

This initial in vitro study aimed at increasing our understanding of the mechanism of action of these phytochemicals to control APEC strain (the causative agent of colibacillosis disease in poultry) with multiple antibiotic-resistance, which will

Carbapenem-resistant Acinetobacter baumannii from Air and Patients of Intensive Care Units

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

Safety Evaluation of Enterocin Producer Enterococcus sp. Strains Isolated from Traditional Turkish Cheeses

. Multiple enterocin structural genes were found in 7 strains. None of the tested enterococci demonstrated anyβ-haemolytic activity and only one strain had gelatinase activity. 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.

Epidemiological situation regarding SAG infections in Poland has been unrecognized, therefore we performed a retrospective analysis of strains isolated between 1996 and 2012. 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

Emergence of High-level Gentamicin Resistance among Enterococci Clinical Isolates from Burn Patients in South-west of Iran: Vancomycin Still Working

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

Expression of the Fluoroquinolones Efflux Pump Genes acrA and mdfA in Urinary Escherichia coli Isolates

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

Bacteriological, Clinical and Virulence Aspects of Aeromonas-associated Diseases in Humans

scepticemia, skin, eye, wound and respiratory tract infections in humans. 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

Moreover, in the bacilli of K. pneumoniae blaNDM genes are located mainly on the following plasmids, i.e. IncA/C, IncF, IncR, IncH, IncN, IncL/M or IncX [45].

Polish Physicians’ Attitudes Towards Antibiotic Prescription and Antimicrobial Resistance

Antimicrobial resistance has been one of the biggest global current issues in medicine and public health. 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
