The Effect Of Staphylococcus Aureus On Stiffness Of Cortical Bone, Ariel N. Kunde
The Effect Of Staphylococcus Aureus On Stiffness Of Cortical Bone, Ariel N. Kunde
Graduate Theses
Osteomyelitis, a term for bone infection, is a common cause of hospitalization in the United States. Infection leading to osteomyelitis is almost always a product of bacterial origin. Although polymicrobial presence is seen at infection sites of osteomyelitis, Staphylococcus aureus is most commonly isolated and found to be the cause of more than 95% of bone infection in adults. This organism is a common commensal of humans that is carried by an estimated 60% of the US population. S. aureus is transferred by infected asymptomatic individuals, and its ability to proliferate under a variety of environmental conditions contributes to the …
Role Of The Interleukin-22 And Stat3 Signaling Pathway In Gut Barrier Maintenance Following Intoxication And Burn Injury, Adam M. Hammer
Role Of The Interleukin-22 And Stat3 Signaling Pathway In Gut Barrier Maintenance Following Intoxication And Burn Injury, Adam M. Hammer

More than half of patients admitted to burn centers for treatment have measurable alcohol levels in their blood. Intoxication that precedes a traumatic burn injury leads to worsened patient outcomes, including higher rates of infection and sepsis. The intestines harbor the largest concentration of bacteria in the human host. Any disruption of the intestinal barrier as a result of intoxication and burn injury could contribute to infection and/or sepsis from gut-derived microbes. Previous work has demonstrated that the intestinal barrier becomes leaky, and that administration of interleukin-22 (IL-22) significantly reduces gut barrier leakiness following alcohol and burn injury. However, the …
Role Of Intracellular Growth During The Gastrointestinal Stage Of Listeria Monocytogenes Infection, Grant Steven Jones
Role Of Intracellular Growth During The Gastrointestinal Stage Of Listeria Monocytogenes Infection, Grant Steven Jones
Theses and Dissertations--Microbiology, Immunology, and Molecular Genetics
Listeria monocytogenes is a facultative intracellular bacterium that causes foodborne disease in humans. L. monocytogenes invade the gut mucosa and then disseminate, causing systemic infections associated with high mortality rates in immunocompromised individuals. It is unknown how L. monocytogenes traffic to the mesenteric lymph nodes, which represent an important bottleneck for systemic spread. In addition, little is known about the gastrointestinal stage of infection due to the general resistance of mice to oral infection with L. monocytogenes. Our laboratory developed a novel foodborne mouse model of listeriosis utilizing a murinized strain of L. monocytogenes to investigate the gastrointestinal stage …
