Statistical Optimization of Bacterial Cellulose Production and Its Application for Bacteriophage Immobilization.

Bacterial cellulose (BC), an extracellular polysaccharide synthesized by various bacterial strains. It exhibits high tensile strength, water retention, crystallinity, and biocompatibility, making it valuable in biomedical, cosmetic, food, textile, and paper industries. This study examined the effects of six carbon sources on BC production by , identifying fructose as the most effective.

Bacteriophages Improve the Effectiveness of Rhamnolipids in Combating the Biofilm of .

Biofilms formed by pose therapeutic challenges due to their resistance to conventional antimicrobials, highlighting the need for more effective treatments. Rhamnolipids (RLs) are biosurfactants with diverse antimicrobial properties. Bacteriophages are viruses that target specific bacterial strains.

Application of UPWr_E124 phage cocktail for effective reduction of avian pathogenic Escherichia coli in mice and broiler chickens.

Avian pathogenic Escherichia coli (APEC) is the main causative agent of colibacillosis, causing poultry respiratory infections, mortality and economic loss. APEC poses a serious threat to public health and food safety due to its multi-drug resistance and capacity to form biofilms. Bacteriophages (phages) have emerged as an alternative to antibiotics.

Avian pathogenic Escherichia coli-targeting phages for biofilm biocontrol in the poultry industry.

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 and its ability to form biofilms on food and processing surfaces contributes to its persistence within farms. Bacteriophages are promising antibacterial agents for combating APEC.

Bioinorganic Chemistry Meets Microbiology: Copper(II) and Zinc(II) Complexes Doing the Cha-Cha with the C-t-CCL-28 Peptide, Dancing till the End of Microbes.

The necessity to move away from conventional antibiotic therapy has sparked interest in antimicrobial peptides (AMPs). One fascinating example is human CCL-28 chemokine produced by acinar epithelial cells in the salivary glands. It can also be released into the oral cavity with saliva, playing a crucial role in oral protection.

Metal coordination governs the antimicrobial efficacy of calcitermin derivatives.

Antimicrobial peptides are promising alternatives to classical antibiotics. Their microbicidal activity can arise from different mechanisms, one of which is known as nutritional immunity and has metal micronutrients and metal-binding biomolecules as its main players. Calcitermin is an antimicrobial peptide and an effective metal chelator.

Freeze-Drying of Encapsulated Bacteriophage T4 to Obtain Shelf-Stable Dry Preparations for Oral Application.

Therapeutic application of bacterial viruses (phage therapy) has in recent years been rediscovered by many scientists, as a method which may potentially replace conventional antibacterial strategies. However, one of the main problems related to phage application is the stability of bacterial viruses. Though many techniques have been used to sustain phage activity, novel tools are needed to allow long-term phage storage and application in versatile forms.

Effective reduction of Enteritidis in broiler chickens using the UPWr_S134 phage cocktail.

is a poultry-associated pathogen that is considered one of the most important zoonotic bacterial agents of contaminated food of animal origin including poultry products. Many efforts are taken to eliminate it from the food chain, and phages are one of the most promising tools to control in poultry production. We investigated the usefulness of the UPWr_S134 phage cocktail in reducing in broiler chickens.

Characterization and Comparative Genomic Analysis of Three Virulent Bacteriophages with the Potential to Reduce Antibiotic-Resistant Bacteria in the Environment.

The emerging global crisis of antibiotic resistance demands new alternative antibacterial solutions. Although bacteriophages have been used to combat bacterial infections for over a century, a dramatic boost in phage studies has recently been observed. In the development of modern phage applications, a scientific rationale is strongly required and newly isolated phages need to be examined in detail.

Bacteriophage Cocktail Can Effectively Control Biofilm in Poultry Housing.

serovar Enteritidis (. Enteritidis) is the major contaminant of poultry products, and its ability to form biofilms on produced food and poultry farm processing surfaces contributes to transmission to humans. Bacteriophages have come under increasing interest for anti- biofilm control.

Genomic and functional characterization of five novel Salmonella-targeting bacteriophages.

Background: The host-unrestricted, non-typhoidal Salmonella enterica serovar Enteritidis (S. Enteritidis) and the serovar Typhimurium (S. Typhimurium) are major causative agents of food-borne gastroenteritis, and the host-restricted Salmonella enterica serovar Gallinarum (S.

Applications of bacteriophages against intracellular bacteria.

Infectious diseases pose a significant threat to both human and animal populations. Intracellular bacteria are a group of pathogens that invade and survive within the interior of eukaryotic cells, which in turn protect them from antibacterial drugs and the host immune system. Limited penetration of antibacterials into host cells results in insufficient bacterial clearance and treatment failure.

Bacteriophage amplification - A comparison of selected methods.

The bactericidal properties of bacteriophages have been used almost since the moment of the discovery of bacterial viruses. In the light of the rapidly growing number of antibiotic-resistant bacteria, phage therapy is considered one of the most promising alternatives to classical treatment. Phage amplification is one of the most common procedures of working with phages, and high-titer preparations are beneficial at the experimental stage of studies as well as in practice.

The Efficacy of Isolated Bacteriophages from Pig Farms against ESBL/AmpC-Producing from Pig and Turkey Farms.

Extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases are plasmid (but also chromosomally) encoded enzymes found in Enterobacteriaceae, determining resistance to a variety of important antibiotics including penicillins, cephalosporins, and monobactams. In recent decades, the prevalence of ESBL/AmpC-producing bacteria has increased rapidly across the world. Here, we evaluate the potential use of bacteriophages in terms of a reduction of antibiotic-resistant bacteria in healthy animals.
