Staphylococcus aureus is a bacteria that can exist asymptomatically, but can be dangerous due to it’s individual toxin profile. These various toxins, however, seem to be mutually exclusive from another in some cases. Samples of S. aureus often have superantigen SELX and some samples have Staphylococcal Enterotoxin (SE) A, B, or C. Through the use of Airtable and various methods of data organization and comparison on the strains we’ve collected on campus, we found that SELX exhibits an inverse relationship with SE- A/B/C, and that SE- A/B/C also exhibits exclusivity between the three toxins. Through thorough research on S. aureus, …

Acinetobacter was discovered in 1911 by Martinus Beijerinck. Acinetobacter baumannii didn't receive its scientific name until 1986. A. baumannii is now commonly referred to as "Iraqibacter" due to a rise in infections among US military personnel returning from Iraq and Afghanistan. After the Iraq War began in 2003, the frequency of cases began to rise, especially among patients in intensive care units. Patients using ventilators, catheters, have postoperative wounds, stay in the hospital for an extended period of time, or are immunocompromised are at a considerably higher risk of getting A. baumannii. Because of its large number of virulence …
Syndemics And Social Factors: Infectious Disease Patterns Within The Population Of People Experiencing Homelessness In The United States, Kathleen Berzonsky
Syndemics And Social Factors: Infectious Disease Patterns Within The Population Of People Experiencing Homelessness In The United States, Kathleen Berzonsky

Individuals experiencing homelessness are at increased risk of suffering from infectious diseases. This is due to a number of social factors and healthcare disparities, as well as the idea of syndemics, by which diseases cluster together to worsen disease burden. Current intervention strategies approach treatment from a post-infection perspective, but reducing transmission rates of infectious diseases within the population of people experiencing homelessness will require a shift in the healthcare framework. The issue of people experiencing homelessness must be viewed through a biosocial lens, focusing on preventative care and treatment. I provide an overview of the social factors governing infectious …

(Summary) Tick microbiota can be targeted for the control of tick-borne diseases such as human granulocytic anaplasmosis (HGA) caused by model pathogen, Anaplasma phagocytophilum. Frankenbacteriosis is inspired by Frankenstein and defined here as paratransgenesis of tick symbiotic/commensal bacteria to mimic and compete with tick-borne pathogens. Interactions between A. phagocytophilum and symbiotic Sphingomonas identified by metaproteomics analysis in Ixodes scapularis midgut showed competition between both bacteria. Consequently, Sphingomonas was selected for frankenbacteriosis for the control of A. phagocytophilum infection and transmission. The results showed that Franken Sphingomonas producing A. phagocytophilum major surface protein 4 (MSP4) mimic pathogen and reduce infection …

Spatial heterogeneity and migration of hosts and ticks have an impact on the spread, extinction and persistence of tick-borne diseases. In this paper, we investigate the impact of between-patch migration of white-tailed deer and lone star ticks on the dynamics of a tick-borne disease with regard to disease extinction and persistence using a system of Itô stochastic differential equations model. It is shown that the disease-free equilibrium exists and is unique. The general formula for computing the basic reproduction number for all patches is derived. We show that for patches in isolation, the basic reproduction number is equal to the …
