An alkaline agent, namely food additive grade calcium hydroxide (FdCa (OH)) in the powder form, was evaluated for its bactericidal efficacies in chicken feces at pH 13. The point for this evaluation was neutralization of the alkaline agent's pH at the time of bacterial recovery, since otherwise the results are substantially misleading. Without neutralization of the FdCa (OH) pH, the spiked bacteria were killed within min at the time of recovery in aqueous phase, but not in the solid form in feces, hence, it has been demonstrated that when bacteria were in solid, it took longer time than in liquid for the alkaline agent to inactivate them down to the acceptable level (≥3 log CFU/ml).

Neisseria gonorrhoeae is an on-going public health problem due in part to the lack of success with efforts to develop an efficacious vaccine to prevent this sexually transmitted infection. The gonococcal transferrin binding protein B (TbpB) is an attractive candidate vaccine antigen. However, it exhibits high levels of antigenic variability, posing a significant obstacle in evoking a broadly protective immune response.

The interaction of protein with nanoparticles (NPs) of varying shape and/or size boosts our understanding on their bioreactivity and establishes a comprehensive database for use in medicine, diagnosis, and therapeutic applications. The present study explores the interaction between lysozyme (LYZ) and different NPs like graphene oxide (GO) and zinc oxide (ZnO) having various shapes (spherical, 's', and rod-shaped, 'r') and sizes, focusing on their binding dynamics and subsequent effects on both the protein fibrillation and antimicrobial properties. Typically, GO is considered a promising medium due to its apparent inhibition and prolonged lag phase for LYZ fibrillation.

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.

A novel molecular design based on a quinazolinone scaffold was developed the attachment of aryl alkanesulfonates to the quinazolinone core through a thioacetohydrazide azomethine linker, leading to a new series of quinazolinone-alkanesulfonates 5a-r. The antimicrobial properties of the newly synthesized quinazolinone derivatives 5a-r were investigated to examine their bactericidal and fungicidal activities against bacterial pathogens like , (Gram-positive), , , (Gram-negative), in addition to (unicellular fungal). The tested compounds demonstrated reasonable bactericidal activities compared to standard drugs.

Multidrug-resistant (MDR) bacteria and their associated biofilms are major causative factors in eye infections, often resulting in blindness and presenting considerable global health challenges. Presently, mechano-bactericidal systems, which combine distinct topological geometries with mechanical forces to physically induce bacterial apoptosis, show promising potential. However, the physical interaction process between current mechano-bactericidal systems and bacteria is generally based on passive diffusion or Brownian motion and lacks the force required for biofilm penetration; thus, featuring low antibacterial efficacy.
