Vitro Bacteriophage Treatment For A Staphylococcus Aureus And Pseudomonas Aeruginosa Co-Culture, Alexis Perry
Arkansas Women in STEM Conference
Recent studies show that up 27-36% of all infections are polymicrobial, involving more than one bacteria species. In all categories, polymicrobial infections are often more virulent and harmful to the patient. Since different types of bacteria can communicate with each other through quorum-sensing when in the presence of each other, they can display different genomic characteristics. Further research into polymicrobial infections needs to be done because these changing characteristics can prevent treatment from working, such as antibiotics or bacteriophage therapy. This experiment focused on the co-culture between the two bacteria, Pseudomonas aeruginosa and Staphylococcus aureus, which can be found co-existing …

Antibiotic resistance is a global healthcare concern because it poses a threat to effectively treating bacterial infections and the need for alternative therapeutics are urgently required. Phage therapy, which uses viruses to treat bacterial infections, is a promising alternative to conventional antibiotics. Phages have also been widely used in the food industry to prevent microbial growth on certain foods and are currently being explored as a method for bioremediation of oil spills and wastewater treatment. Although phages are ubiquitous in nature, many have yet to be discovered. Through the SEA-PHAGES (Science Education Alliance-Phage Hunters Advancing Genomics and Evolutionary Science) program …

Enteroviruses are single stranded RNA viruses which have caused many public health concerns, particularly in children. These viruses are responsible for polio, hand, foot, and mouth disease, many polio-like neurological diseases, and the common cold. The enterovirus called Coxsackievirus B3 (CVB3), a close relative to poliovirus, has been shown responsible for severe human disease, including pancreatitis, myocarditis, and type 1 diabetes. A unique advantage of studying CVB3 is the existence of a naturally occurring strain (CVB3/GA) which displays no known pathogenicity. Earlier comparative genomic studies have shown that the primary difference between avirulent CVB3/GA and the virulent strains of CVB3 …

Bacteriophages are viruses that infect bacteria and reproduce using host bacterial components. Part of the bacteriophage reproduction is assembly of the tail complex, which requires two assembly chaperone (TAC) proteins. In many phages the TAC’s are produced from a single gene through a non-canonical process called programmed translational frameshifting (PTF). The SEA-PHAGES program has produced hundreds of TAC genes that are accessible through phagesdb, a database of sequenced and annotated phage genomes. The sequences for the TAC gene were gathered from phagesdb and analyzed using ClustalOmega; a multiple sequence alignment (MSA) tool which revealed several positions where total conservation was …

Human cytomegalovirus (HCMV) is a prevalent pathogen that causes little disease except in immune-compromised hosts. HCMV establishes life-long latency by manipulating host immune responses. We have found that the US27 protein profoundly alters the activity of host chemokine receptor CXCR4. Cells expressing US27 and CXCR4 exhibited greater migration and calcium signaling than cells expressing CXCR4 alone. The mechanism for this enhanced signaling appears to be increased expression of CXCR4, and we are continuing to investigate how US27 causes up-regulation of CXCR4. This work is expected to clarify the role of US27 in immune evasion and provide insights into treatment strategies.
