Mastitis is one of the most important diseases cows and expensive pathology for dairy industry. Therefore, this study was conducted to explore role microorganisms isolated from with mastitis in formation biofilms under conditions farm biogeocenosis Moscow region.Periodic visits 12 farms region were microbial profile udder mastitis. During visits, 103 milk samples sick animals collected examined. Through microbiological analyses, 486 cultures identified, which are assigned 11 genera. caused...

Candida albicans was the first eukaryotic microorganism to exhibit quorum-sensing through secretion of sesquiterpene E, farnesol. This molecule is generated by dephosphorylation farnesyl pyrophosphate in mevalonate biosynthetic pathway mammalian and yeast cells. Exogenous farnesol inhibits yeast-to-hyphal formation a concentration- time-dependent manner at earliest stage hyphal development. Much research has been devoted studying role as an inhibitor morphogenesis; however, little published...

Expandable metallic stent placement is often the only way to treat airway obstructions. Such treatment with an uncoated causes granulation proliferation and subsequent restenosis, resulting in procedure’s adverse complications. Systemic administration of steroids drugs high dosages slows down tissue overgrowth but leads long-term side effects. Drug-eluting coatings have been used widely cardiology for many years suppress local reduce organism’s systemic load. Still, so far, there are no...

Clinical strains of microorganisms, including pathogenic yeast-like fungi (YLF), are resistant to currently used antifungal agents. Thus, it is relevant study the combinations existing antimicrobial drugs and a medicinal extract plant origin (farnesol). In previous studies, farnesol showed relatively strong anti-biofilm effect against Candida albicans. This aimed determine how much resistance profile non-biofilm microorganisms can change. Six clinical isolates C. albicans one reference...
