The Nipah virus (NiV) is a member of the Paramyxoviridae family of zoonotic viruses that is extremely contagious and potentially fatal. The Nipah virus was first discovered in 1999 during an outbreak in Malaysia. Since then, it has periodically caused outbreaks throughout South and Southeast Asia, especially in Bangladesh and India, and it continues to be a serious public health concern. The virus is primarily transmitted to humans through direct contact with infected fruit bats, which serve as natural reservoir hosts for the Nipah virus. Human-to-human transmission can also happen when infected people's body fluids come into close contact with one another. The Nipah virus has a high death rate that varies depending on the outbreak and can cause a variety of clinical presentations, including encephalitis, severe respiratory illnesses, and asymptomatic infections. Fever, headache, dizziness, drowsiness, and confusion are common signs of Nipah virus infections, which may lead to the rapid onset of coma in the patient. The Nipah virus does not presently have a specific antiviral treatment; instead, infection control methods and supportive care are the foundation of management to stop the virus from spreading. Nipah virus outbreaks must be stopped with an approach that includes community involvement, public health education, and surveillance of both human and animal populations. Additionally, efforts are directed toward developing vaccines as a more potent form of prevention. The Nipah virus is a clear reminder of the continuous threat that newly emerging infectious diseases pose, as well as the necessity of having strong surveillance systems and quick response times in place to lessen the effects that these outbreaks have on public health.

“…Intrinsic factors like an individual's sex, age, genetic makeup, and immune reactivity all have been recognized to alter the skin 9 . For example, males tend to sweat more and harbour a lot more hair than females, thus creating more niches in moist environments 3,10 . Age is also an influencing factor on which organisms can proliferate on the skin; as the skin matures over time, it can become weaker, more wrinkled, looser, and drier 9,10 .…”

Investigating Microbial Interactions of Pseudomonas Aeruginosa and Staphylococcus Epidermidis in Mixed Biofilms: Implications for Chronic Biofilm Infections

Chronic wounds are sores that typically take longer than three months to heal as the key mechanisms involved are impaired. In tandem with an impaired immune system, biofilms are observed and found to impact wound repair processes. The microbial composition of wounds is diverse, and the bacterial bioburden influences wound outcome. Commensals and environmental microbes occupy these wounds, however, only pathogenpathogen interactions have been explored thoroughly whereas commensals like Staphylococcus epidermidis (S. epidermidis) have only recently garnered interest. Established a mixed biofilm of S. epidermidis and common chronic wound pathogen Pseudomonas aeruginosa (P. aeruginosa) to investigate commensal-pathogen interspecies interactions, specifically on the antimicrobial resistance and virulence factor production of P. aeruginosa. Attenuated susceptibility of P. aeruginosa to anti-pseudomonal antibiotic ciprofloxacin was documented when co-cultured together with S. epidermidis in mixed biofilm. Proteins and extracellular metabolites within the supernatant of S. epidermidis demonstrated similar attenuation in antibiotic resistance of P. aeruginosa, although the active biological compounds remain unknown. Virulence factors of P. aeruginosa, pyocyanin and pyoverdine, were analyzed and demonstrated varying effects in dual-mixed biofilms with S. epidermidis based on iron availability. However, follow-up analyses revealed pyoverdine was not a major factor in contributing to the decrease in S. epidermidis viability in co-cultured biofilms. The research completed advances the knowledge of microbial interactions within chronic wounds, particularly the interactions between S. epidermidis and P. aeruginosa, and contributes to our understanding of how antibiotic resistance is affected in polymicrobial biofilms. This data provides new avenues to vii developing therapies that utilize probiotics to weaken once-resistant microbes to antibiotics in an effort to combat the rising antimicrobial resistance issue. viii Acknowledgments ‫بسم‬ ‫هللا‬ ‫الرحمن‬ ‫الرحيم‬ In the name of Allah, the Most Gracious, the Most Merciful This research project would not have been possible without the support of the brilliant colleagues, family, and friends I have made over these past two years. First, I would like to express my deepest gratitude to my supervisor Dr. Joerg Overhage who has continuously been a bright light throughout this journey. Your guidance and mentorship allowed me to develop as a student and thrive as a researcher in this fascinating, neverending field. You have been a constant cheerleader in my work and have always saw the potential in me, especially in times when I could not. Thank you for inspiring us to be our best selves, think outside the box, and making the MicrO lab my second family. I am forever grateful for this opportunity and will never forget the time I was your student. I am extremely thankful to my graduate advisory committee, Dr. Edana Cassol and Dr. Daniel Pletzer for their guidance and advice to help me gro...
