Milan Kolář
Bacterial resistance may be defined from a microbiological, clinical and pharmacological perspective. Microbiological resistance refers to the presence of genetic information coding for the relevant mechanism of resistance of a bacterium to a particular antibiotic. In case of clinical interpretation, breakpoints are of key importance as their role is to distinguish bacterial pathogens in which successful therapy is highly probable from isolates with a high likelihood of failure. However, it is questionable whether this approach is suitable for all patients, particularly those receiving intensive care for life-threatening infections...

Lyme borreliosis is the most frequent tick-borne infection in Europe. It is a multisystemic disease affecting the skin, joints, heart, in rare cases the eyes and regularly the nervous system. Taking current clinical and microbiological guidelines into account, neuroborreliosis can in general be diagnosed and treated successfully. An appropriate guideline-conform antibiotic treatment is effective and in most cases recovery from acute neuroborreliosis is complete. Nevertheless, the evidence base regarding pharmacological treatment needs reform and improvement...

This study presented a septic shock occurring with striking speed during the percutaneous drainage of a large abscess of the liver in an 18-year-old female patient after an appendectomy performed 3 months earlier using the laparoscopic method because of its phlegmonous and gangraenosus inflammation. The post-operative course was complicated by increased suppuration in places after removal of the trocars. After including the intravenous antibiotic therapy and under the USG control, the percutaneous drainage of the abscess was performed...

An interventional study was performed to determine and compare the MICs of aqueous garlic extract (AGE) and Imipenem against standard strains of Staphylococcus aureus ATCC 25923 & Eschericha coli ATCC 25922. The study was conducted in Department of Pharmacology and Therapeutics in collaboration with Department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to January 2015. The MIC of AGE and antibiotic Imipenem were determined with the help of broth dilution method. The MIC of AGE was determined as 400μg/ml and 700μg/ml against Staphylococcus aureus, and Escherichia coli respectively and the MIC of Imipenem was 1μg/ml against Staphylococus aureus and 1...

Omadacycline is a first-in-class aminomethylcycline antibiotic that circumvents common tetracycline resistance mechanisms. In vitro omadacycline has potent activity against Gram-positive aerobic bacteria including methicillin-resistant Staphylococcus aureus, penicillin-resistant and multidrug-resistant Streptococcus pneumoniae, and vancomycin-resistant Enterococcus spp. It is also active against common Gram-negative aerobes, some anaerobes and atypical bacteria including Legionella spp. and Chlamydia spp. Ongoing Phase III clinical trials with omadacycline are investigating once daily doses of 100 mg intravenously followed by once daily doses of 300 mg orally for the treatment of acute bacterial skin and skin structure infections and community-acquired bacterial pneumonia...

Omadacycline is novel, aminomethyl tetracycline antibiotic being developed for oral and intravenous (IV) administration for the treatment of community-acquired bacterial infections. Omadacycline is characterized by an aminomethyl substituent at the C9 position of the core 6-member ring. Modifications at this position result in an improved spectrum of antimicrobial activity by overcoming resistance known to affect older generation tetracyclines via ribosomal protection proteins and efflux pump mechanisms. In vitro, omadacycline has activity against Gram-positive and Gram-negative aerobes, anaerobes, and atypical pathogens including Legionella and Chlamydia spp...

The research on antibiotics requires the integration of broad areas, such as microbiology, organic chemistry, biochemistry and pharmacology. It is similar to the field of chemical biology that is recently popular as an approach for drug discovery. When we isolate a new compound from a microorganism, we can pursue the interesting research on chemistry and biology. In this review, I would like to introduce our achievements in relation to reveromycin A.The Journal of Antibiotics advance online publication, 8 June 2016; doi:10...

Bone cement has the capacity to release antibiotic molecules if any antibiotic is included in it, and these elution properties are improved as cement porosity is increased. In vitro studies have shown high local antibiotic concentration for many hours or few days after its use. Antibiotic loaded bone cement (ALBC) is helpful when treating an infection in total knee arthroplasty (TKA) revision surgery. The purpose of this paper was to review the evidence for the routine use of ALBC in TKA in the literature, its pros and cons...

BACKGROUND: The last years have witnessed progressive growth of antimicrobial resistance (AMR) both in hospital-acquired and community-acquired respiratory infections. Regional guidelines (2006) presented standard approaches to pharmacotherapy and provided an important contribution to improvement of antimicrobial therapy at healthcare facilities of both the City of Stavropol and the Stavropol Region. At the same time, recent years have witnessed substantial changes in sensitivity to antimicrobials; besides, newer antibiotics have become available now...

Although pharmacological treatment of COPD exacerbation (COPDE) includes antibiotics and systemic steroids, a proportion of patients show worsening of symptoms during hospitalization that characterize treatment failure. The aim of our study was to determine in-hospital predictors of treatment failure (≤ 7 days). Prospective data on 110 hospitalized COPDE patients, all treated with antibiotics and systemic steroids, were collected; on the seventh day of hospitalization, patients were divided into treatment failure (n = 16) or success (n = 94)...

Limited data exist evaluating outcomes in patients with serious Streptococcus anginosus group infections, particularly bacteraemia. A retrospective, single-centre cohort study was conducted to characterize potential risk factors along with clinical and microbiological outcomes in patients with S. anginosus group bacteraemia (SAGB). Adult inpatients with SAGB identified using the Verigene Gram-positive blood culture assay between March 2013 and April 2014 were included. Patients aged ≤ 18 or >89 years, those with SAGB identified at an outside facility and those who were incarcerated were excluded...

Bacterial infections are major complications after Hematopoietic Stem Cell Transplant (HSCT). They consist mainly of bloodstream infections (BSI), followed by pneumonia and gastrointestinal infections, including typhlitis and Clostridium difficile infection. Microbiological data come mostly from BSI. Coagulase negative staphylococci and Enterobacteriaceae are the most frequent pathogens causing approximately 25% of BSI each, followed by enterococci, P. aeruginosa and viridans streptococci. Bacterial pneumonia is frequent after HSCT, and Gram-negatives are predominant...

Management of acute dental infections requires an understanding of microbiology, anatomy, pharmacology, wound healing, and oral surgery. Recognizing early signs of inflammation and differentiating them from characteristics of an infection facilitates timely intervention and avoids further complications. This article addresses various aspects of the diagnosis and treatment of acute oral infections. Suggestions are made to help differentiate between swelling associated with an infection and edema related to inflammation of nonpathogenic origin...

Pharmaceutical industry has been encountering antimicrobial activity of non-antibiotics during suitability tests carried out prior to routine pharmacopoeial microbiological purity analysis of finished dosage forms. These properties are usually ignored or perceived as a nuisance during pharmaceutical analysis. The aim of this study was: (i) to compare the available data to our method suitability test results carried out on products containing ibuprofen, i.e. to demonstrate that method suitability can be a valuable tool in identifying new antimicrobials, (ii) to demonstrate the antimicrobial activity of ibuprofen and ibuprofen lysine...
