Avian pathogenic Escherichia coli (APEC) is a principal etiologic agent of avian colibacillosis, responsible for significant economic losses in the poultry industry due to high mortality and disease treatment with antibiotics. APEC its ability form biofilms on food processing surfaces contributes persistence within farms. Bacteriophages are promising antibacterial agents combating APEC. This study focused characterization newly isolated phages UPWr_E1, UPWr_E2, UPWr_E4 as well UPWr_E124 phage...
Due to the rapid spread of antibiotic resistance, and difficulties treating biofilm-associated infections, alternative treatments for
Listeriosis is an infection caused by the consumption of food contaminated with Listeria monocytogenes. It leads to febrile gastroenteritis, central nervous system infections, and even death in risk populations. Bacteriophage endolysins selectively kill bacteria hydrolyzing their cell walls have emerged as a potential tool for listeriosis control. Ply511 anti-Listeria endolysin that has activity against all serovars L. The yeast Saccharomyces cerevisiae been used produce biocontrol, but...
This study focused on the performance of dextran producer Leuconostoc citreum as starter culture during 30 days wheat flour type I sourdough propagation (back-slopping). As confirmed by RAPD-PCR analysis, strain dominated throughout procedure, consisting daily fermentations at 20 °C. The sourdoughs were characterized consistent lactic acid bacteria cell density and acidification parameters, reaching pH values 4.0 mild titratable acidity. Carbohydrates consumption remained leading to...
Salmonella is a poultry-associated pathogen that considered one of the most important zoonotic bacterial agents contaminated food animal origin including poultry products. Many efforts are taken to eliminate it from chain, and phages promising tools control in production. We investigated usefulness UPWr_S134 phage cocktail reducing broiler chickens. For this purpose, we analyzed survivability harsh environment encountered chicken gastrointestinal tract, which has low pH, high temperatures,...
Abstract Cellodextrins are non-digestible oligosaccharides that have attracted interest from the food industry as potential prebiotics. They typically produced through partial hydrolysis of cellulose, resulting in a complex mixture with varying degree polymerisation (DP). Here, we explore defined synthesis cellotriose product since this oligosaccharide is believed to be most potent prebiotic mixture. To end, cellobiose phosphorylase (CBP) Cellulomonas uda and cellodextrin (CDP) Clostridium...
Alternative treatments for Escherichia coli infections are urgently needed, and phage therapy is a promising option where antibiotics fail, especially urinary tract (UTI). We used wastewater-isolated phages to test their lytic activity against panel of 47 E. strains reflecting the diversity found in UTI, including sequence type 131, 73 69. The plaquing host range (PHR) was between 13 63%. In contrast, kinetic (KHR), describing percentage which growth suspension suppressed 24 h, 0% 19%,...
S. aureus is a pathogen that frequently causes severe morbidity and phage therapy being discussed as an alternative to antibiotics for the treatment of infections. In this in vitro animal study, we demonstrated activity anti-staphylococcal phages severely impaired 0.5% plasma or synovial fluid. Despite replication these matrices, lysis bacteria was slower than propagation, no reduction bacterial population observed. The inhibition associated with adsorption, quantified 99% at 10% plasma....
Abstract S. aureus is a pathogen that frequently causes severe morbidity and phage therapy being discussed as an alternative to antibiotics for the treatment of infections. In this in vitro animal study, we demonstrated activity anti-staphylococcal phages severely impaired plasma synovial fluid. Despite replication these matrices, lysis bacteria was slower than propagation, no reduction bacterial population observed. This inhibition due 99% adsorption, already at 10% concentration....
