A systematic review was carried out to identify and compile data on infectious agents known to cause pandemics and those that pose future concerns. One hundred and fifteen articles were included in the review. They provided insights on 25 pathogens that could start or contribute to creating pandemic situations. Diagnostic procedures, clinical symptoms, and infection transmission routes were analyzed for each of these pathogens. Each infectious agent's potential is discussed, shedding light on the crucial aspects that render them potential threats to the future.

The accumulated QS signals in the external environment reach a threshold concentration when the bacterial population attains a certain density, enabling effective recognition and interaction of bacterial QS signals with their receptors. This leads to coordinated gene expression and various biological activities across the bacterial population. Targeting the QS system presents a promising strategy to hinder biofilm formation and virulence factor secretion, providing a potential approach to control bacterial growth and reproduction. This study aims to analyze the intercellular mechanisms of quorum quenching (QQ), which focuses on disrupting bacterial signal molecules to keep their concentration below the threshold and preventing the expression of specific pathogenic factors.

Although much research has been done on human lactoferrin (hLF), LF derived from different animals is equally essential for physiology and health. Depending on the intended application and mechanism of action, goods containing LF and its peptide derivatives may be classified as medical devices under FDA rules or EU Directives. For EU and FDA regulations, a product may be categorized as a medical device if it primarily provides antimicrobial or health advantages. However, LFs are not considered as medical device when used as a food addition or supplement without particular medicinal claims. Safety and efficacy data are examined for regulatory approval in this category to guarantee its appropriate usage and usefulness in clinical settings. When utilized in various medicinal applications, including wound healing, gastrointestinal problems, and immune system stimulation, the complex nature and potential health advantages of LFs and their derivatives would be consistent with their categorization as a class II medical device.

Oral infections are major health problems that affect the standard of living. Compromised oral health is related to chronic conditions and systemic disorders. Microbes responsible for dental caries are acid-producing and aciduric Gram-positive bacteria (Streptococci, Lactobacilli).

Due to the high prevalence of oral diseases, negative effects associated with the use of antimicrobial agents and increased antibiotic resistance in oral pathogens, suitable alternative methods (effective, economical and safe) to suppress microbes disturbing oral health need to be adopted. Side effects associated with the chemical antimicrobial agents are vomiting, diarrhea and tooth staining.
