A serious complication of hernioplasty with the use of a biomaterial implant is deep surgical site infection (SSI) encompassing the implant. Among the most common etiological factors of deep SSI in patients after hernioplasty are Staphylococcus aureus and Escherichia coli strains, which may create a biofilm on the surface of synthetic implants. The aim of this study was assessment of biofilm formation by S. aureus and E. coli on the surface ofpolypropylene mesh. The study included 108 strains (62 S. aureus and 46 E. coli) from the collection of Department of Microbiology Collegium Medicum im. L. Rydygier in Bydgoszcz, Nicolaus Copernicus University in Torun (CM UMK). Evaluation of biofilm formation was performed using the method of reduction of 2,3,5-triphenyltetrazolium chloride (TTC) and a scanning electron microscope. In the group of S. aureus strains, 88.7% isolates formed biofilm very strongly, 1.6% strongly, and 9.7% poor. Among E. coli strains, 54.3% isolates were characterized by very strong biofilm formation, while 45.7% strong biofilm formation. Strains ofS. aureus strongly than E. coli form a biofilm on the surface of monofilament polypropylene mesh.

Dental caries is a common disease resulting from tooth demineralization caused by bacterial plaque. Probiotics have shown great potential against caries by regulating the balance of oral flora. However, obstacles such as poor colonization and lysozyme sensitivity in oral cavity hinder their further application.

Despite major efforts toward its eradication, cholera remains a major health threat and economic burden in many low- and middle-income countries. Between outbreaks, the bacterium responsible for the disease, , survives in aquatic environmental reservoirs, where it commonly forms biofilms, for example, on zooplankton. -acetyl glucosamine-binding protein A (GbpA) is an adhesin that binds to the chitinaceous surface of zooplankton and breaks its dense crystalline packing thanks to its lytic polysaccharide monooxygenase (LPMO) activity, which provides with nutrients.

Background: Surgical site infections (SSIs) have been shown to increase patient morbidity and mortality, impact on quality of life and place a significant economic burden on healthcare systems worldwide. Irrigation using wound cleansing and antiseptic effective solutions during surgical procedures is a key part of SSI prevention. The optimal solution would have minimal cytotoxicity to the patient while maintaining a minimum concentration required for antimicrobial activity necessary to prevent opportunistic pathogens and biofilm formation.

Aim: Chronic wound infections present a prevalent medical issue and a multifaceted problem that significantly impacts healthcare systems worldwide. Biofilms formed by pathogenic bacteria are fundamental virulence factors implicated in the complexity and persistence of bacterial-associated wound infections, leading to prolonged recovery times and increased risk of infection. This study aims to investigate the antibacterial effectiveness of commonly employed bioactive wound healing compositions with a particular emphasis on their effectiveness against common bacterial pathogens encountered in chronic wounds - , , and to identify optimal wound product composition for managing chronic wound infections.

Purpose: To assess the impact of anodization and instrumentation on titanium abutment surface characteristics (surface roughness and wettability) and biofilm formation (viability and mass).
Materials And Methods: Titanium discs were obtained from pre-milled abutment blanks made of titanium-6aluminum-7niobium alloy. Polished samples were divided into three groups: un-anodized, gold-anodized, and pink-anodized.
