Laboratory of Microbial Genetics

Research interests

The main objectives of Laboratory of Microbial Genetics are oriented to research of gastrointestinal and skin microflora of companion-, wild-, and farm- animals, including bee. The primary field of focus is monitoring of phenotypic and genotypic antibiotic resistance of gastrointestinal Gamma Proteobacteria (Escherichia coli, Klebsiella sp., Pseudomonas aeruginosa) with focusing to the most important resistance mechanisms such as plasmid ampicillinases, cephalosporinases, carbapenemases, plasmid resistance to fluoroquinolones and resistance to colistin and mammary gland and skin Staphylococcus sp. bacteria to detect dangerous types of resistance as MRSA; MRCoNS; VRSA or MLSB. Moreover, our lab explores the effect of progressive and new eco- friendly combating strategies against animal infection caused by multi-drug resistant biofilm producing bacteria, such as various natural substances (probiotics – bacteriocins; plant-derived bioactive compounds; organic acids; stem cells antimicrobial peptides; metallic element – nanoparticles; bacteriophages etc.). Research focused on testing the antibiotic and antibiofilm effects of selected natural substances provides the basis for the development of new therapeutics that are beneficial not only for veterinary practice (in the management of recurrent infections), but also respect the European Union’s “Farm to Fork” strategy, which represents an essential tool in the fight against antibiotic resistance.
