Increasing Antibiotic Resistance In Shigella Bacteria In The United States, William J. Pharr
Increasing Antibiotic Resistance In Shigella Bacteria In The United States, William J. Pharr
The Corinthian
Shigella bacteria cause half a million infections, 6,000 hospitalizations, and 70 deaths annually in the United States. These bacteria are of particular concern due to their high survivability, low infectious dose, and high adaptability. Cases of shigellosis from Shigella sonnei are becoming a more prevalent issue in the U.S. as the bacteria continues to develop higher resistance to today’s strongest antibiotics. Much of this resistance is connected to the exchange of genes between strains of Shigella due to insertion sequences (IS), intercontinental travel, and men who have sex with men (MSM). As a result of increased resistance, the use of …

Genetic Diversity Of Mycobacteriophages And The Unique Abilities Of Cluster K, Shea A. Morris
The Corinthian
Mycobacteriophage are a diverse set of viruses that infect a broad host range of mycobacterium. Genome analysis of this phage group reveals its diversity and provides evidence that they have experienced substantial horizontal gene transfer Collectively they have a large range of host bacteria they can infect, although each viral type may have a limited host range. However, this range is easily expanded and constantly changing in nature by mutation within and between virus types. These phages can lytically destroy their host mycobacteria, and it is this viral ability that have many mycobacteriophage researchers excited about the potential that phage …
