Chronic inflammation is a significant health concern, damaging tissues and cells, leading to serious diseases like cancer, heart disease, and diabetes. Many anti-inflammatory treatments, suc…
Microbiology
Staphylococcus aureus is a gram-positive pathogenic bacteria that causes community-onset and nosocomial infections, making it a global healthcare threat. Its ability to evade host responses…
Microbiology
Tardigrades are one of the many organisms that have the capability of surviving extreme environments. They do this by going into a stasis known as cryptobiosis including the lack of water kn…
Microbiology
Plant-based natural products are utilized as active ingredients in herbal medicines, and studying their bioactivities is necessary for evaluating their medicinal value. The present study aim…

Second Award
Antibiotic resistance is a major global health threat projected by the World Health Organization to cause 10 million deaths annually by 2050. Autolysins like AtlA, essential for bacterial ce…
Microbiology
Importance: The likelihood of another COVID-19-level pandemic occurring within 100 years is currently predicted to be 17% and is expected to increase to 44% after the next six decades. Emerg…
Microbiology (inferred)
Small Intestinal Bacterial Overgrowth (SIBO) is a poorly understood disease characterized by the overgrowth of bacteria in the small intestine. The current treatment for SIBO is rifamycin an…
Microbiology
Fourth Award
Water contamination poses a global challenge, particularly in regions relying on unlicensed artesian wells for agriculture and livestock without regulatory oversight. This study examines the…
Microbiology
Antibiotic-resistant bacteria threaten a future where even minor infections may become untreatable. This growing concern has renewed interest in an old alternative—phage therapy. Phage thera…
Microbiology
Antibiotics have been the main solution to combat bacterial infections, however their inappropriate use has caused health problems, like dysbacteriosis as well as the development of resistan…
Microbiology
E. coli outbreaks linked to romaine lettuce in Yuma, Arizona, have been a persistent public health concern. This study explores a solution to mitigating bacterial contamination using sonific…
Microbiology
The use of mouthwash is widely recommended by dental professionals and endorsed by organizations such as the American Dental Association for its potential to improve oral hygiene. This exper…
Microbiology
Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 is a powerful technology used for gene editing. While this method has opened many opportunities for scientific advance…
Microbiology
Since the 1930s, antibiotics have revolutionized medicine and saved countless lives from bacterial infections. However, the rise of antimicrobial resistance has increasingly compromised thei…
Microbiology
Halophiles have a vast range of uses, from biofuel production to pharmaceutical applications. Escherichia coli has one of the fastest duplication times of any organism, as low as twenty minu…
Microbiology
Antibiotics are the most commonly used type of medicine currently available. Although this medicine is greatly beneficial towards those who need it, the cost of it can be expensive and dange…
Microbiology
Whole-body deodorants are widely used, yet their impact on the vaginal microbiome is unknown. Many contain antibacterial components that may disrupt Lactobacillus, the dominant bacteria of t…
Microbiology (inferred)
Antibiotic resistance is a critical global health challenge, with the UN estimating that drug-resistant infection deaths will surpass cancer deaths by 2050. Bacteriophages offer a potential…
Microbiology
Aliivibrio fischeri is a single-celled, gram-negative, rod-shaped bacterium that lives within the ocean. When in healthy waters, its cell membrane quorum senses with other bacterium near it…
