Quorum Sensing and Biofilm Dynamics in Pathogens: An Evolving Frontier in Infectious Disease
Abstract: Bacterial and fungal pathogens rarely act as solitary invaders. Instead, they engage in sophisticated chemical communication known as quorum sensing (QS) to coordinate population-wide behaviours and construct structured, multicellular biofilm communities. These biofilms, composed of extracellular polymeric substances, not only facilitate microbial persistence on biotic and abiotic surfaces but also confer remarkable protection against host immune defenses and antimicrobial therapies. QS systems act as central regulators of biofilm dynamics, orchestrating …

Overview of Virulence Factor of Staphylococcus sp.
Abstract: Staphylococcus is a highly virulent genus of bacteria that can cause a range of infections in humans and animals. The production of toxins, enzymes, and biofilms contributes to its ability to establish infections and evade host defenses. Understanding the characteristics and virulence factors of Staphylococcus is crucial for the development of effective prevention strategies and treatment options. Staphylococcus aureus is a significant etiological agent of nosocomial infections on a global …

Antimicrobial Peptides and Bacteriophages as Next-Generation Alternatives to Conventional Antibiotics
Abstract: The growing threat of antibiotic-resistant bacteria has underscored the urgent need for innovative alternatives to conventional antibiotics. Antimicrobial peptides (AMPs) and bacteriophages are gaining recognition as next-generation therapeutics due to their distinct mechanisms of action and ability to target resistant pathogens effectively. AMPs, which can be natural or synthetic, disrupt microbial membranes and offer broad-spectrum antimicrobial activity with a reduced likelihood of resistance development. Bacteriophages, as bacteria-specific viruses, provide precise …

Chemical Composition and Antimicrobial Efficacy of Ferula persica Extracts: A Phytochemical and Bioactivity Assessment in Iraq
Abstract: The research presented in the tables focuses on analyzing the chemical content of extracts from the Ferula persica plant, a wild species in Iraq with significant medical and therapeutic importance dating back to ancient times. This study involved testing some chemical and physical properties of the alcoholic extract of the plant's aerial parts and evaluating its antimicrobial activity, specifically against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). The …

Plant Bioactive Metabolites and Their Role in the Prevention and Control of Dental Diseases and Infections.
Abstract: The oral diseases, including dental caries and periodontitis, affect masses worldwide, and have historically been managed with synthetic antimicrobials that cause deleterious side effects, leading to mounting bacterial resistance. Consequently, contemporary dentistry is rapidly shifting toward phytomedicine using plant bioactive molecules, such as polyphenols, terpenes, anthraquinones (berberin, eugenol, curcumin, catechins, allicin, and azadirachtin. These compounds offer potent antimicrobial, anti-inflammatory, and tissue-regenerative properties that are crucial for preventing and curing dental …

Disease: A Major Stumbling Block in the Growth of Aquaculture
Abstract: Aquaculture plays a crucial role in ensuring food security, fostering economic development, and providing recreational opportunities worldwide. However, the intensification of aquaculture practices has led to a surge in environmental challenges, including water pollution, soil acidification, eutrophication, chemical contamination, and the spread of diseases. Among these, diseases caused by bacteria, viruses, fungi, and parasites pose significant threats to the sustainability of global aquaculture. Despite the implementation of various diagnostic methods …

Review: Virulence factors, resistance genes and pathogenicity of Moraxella catarrhalis
Abstract: An estimated 2-4 million cases of chronic obstructive pulmonary disease(COPD) in adults are exacerbated by Moraxella catarrhalis annually in the US, making it a pathogen of increasing significance for respiratory tract infections. It often colonizes the nasopharynx without causing any symptoms and an opportunistic bacterial infection of the respiratory mucosa that is exclusive to humans. In our study, we reviewed references about the important virulence factors that M. catarrhalis possess …

Pathogens in Nosocomial Infections: Epidemiology, Resistance, and Control Measures
Abstract: Nosocomial infections, also known as healthcare-associated infections (HAIs), are a serious global health issue, leading to higher patient morbidity, prolonged hospital stays, and increased medical costs. Various pathogens—such as bacteria, viruses, fungi, and parasites—are responsible for these infections, especially in healthcare environments where they easily spread. They can be transmitted through direct contact with infected patients, contaminated medical equipment, or even airborne particles.Patients with weakened immune systems, those requiring prolonged …

Marine Fungi – An Expandable Source for Production of Novel Bioactive Metabolites: A Comprehensive Review
Abstract: The marine environment, representing the largest and most extreme biome on Earth, serves as an unparalleled reservoir of biodiversity. Within this vast ecosystem, marine fungi have emerged as a prolific source of structurally diverse and pharmacologically active secondary metabolites. Dwelling in habitats characterized by extreme high salinity, high hydrostatic pressure, and low temperatures, these microorganisms have evolved unique biochemical and metabolic pathways to synthesize novel compounds, including pyrrole-imidazole alkaloids, cyclic …
