Plant-Derived Antimicrobials as Next-Generation Solutions to Multidrug Resistance
Abstract: The steady rise of multidrug-resistant (MDR) pathogens is reshaping how clinicians, researchers, and policymakers think about infection control. When bacteria acquire the ability to survive exposure to three or more antibiotic classes at once—whether through efflux pumps, enzyme-mediated drug destruction, target modifications, or reduced membrane permeability—treatment options narrow dramatically, hospital stays lengthen, and mortality climbs. Conventional pharmaceutical pipelines have struggled to keep pace with this biological arms race, pushing the …

Comparison of the Keratinase Gene Sequences of Fast, Slow and Intermediate Feather Degrading Strains of Bacillus licheniformis
Abstract: Feathers are composed of beta keratin which is an insoluble protein resistant to degradation. Bacillus licheniformis has a gene that codes for a keratinase enzyme that hydrolyzes feathers. The DNA sequences of the genes coding for keratinase enzymes of various strains of B. licheniformis were compared. Some strains of the bacteria hydrolyze feathers rapidly, some slowly, and some at an intermediate rate. The mature keratinase enzyme is composed of 274 …

Occupational Infections and Preventive Measures: An Update
Abstract: There are many infections which are closely associated with certain occupations, whereby the workers are put at a higher risk of being contracted with certain infections in the work setup. Occupational hazards are classified as being either physical (high temperature or pressure) or chemical (organic solvents and chemicals) or biological (virus, bacteria, fungi) hazard. Sometimes the prevalent occupation-associated life-style results in higher risk of exposure to the infections. These hazards …

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 …
