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 …
Impact Of Probiotics On Black Soldier Fly Larvae Transmission Of Stenotrophomonas Maltophilia, Emily Marie Mclaughlin
Impact Of Probiotics On Black Soldier Fly Larvae Transmission Of Stenotrophomonas Maltophilia, Emily Marie Mclaughlin
Honors College
Stenotrophomonas maltophilia is an opportunistic pathogen which can cause a variety of infections, especially in immunocompromised individuals. It has recently been found that black soldier flies can act as carriers for S. maltophilia (Callegari et al., 2020). I have investigated how probiotics impact their vector capabilities. Black soldier fly larvae have been fed substrate spiked with S. maltophilia. After several days of feeding, the larvae were investigated by PCR and plating (Sveensson-Stadler et al., 2011). Two groups of larvae were fed with potatoes infected with S. maltophilia. Persistence of S. maltophilia was determined using PCR by taking samples …
Host Pathogen Interactions: Is Arabidopsis Thaliana Remembered By Its Nemesis Pseudomonas Syringae?, Daniel Z. Kreiser
Host Pathogen Interactions: Is Arabidopsis Thaliana Remembered By Its Nemesis Pseudomonas Syringae?, Daniel Z. Kreiser
Lawrence University Honors Projects
Plants contain innate immune systems that deter pathogen infection. Pattern recognition receptors bind microbe-associated molecular patterns (MAMPs), triggering immunity. MAMPs are proteins exclusive to pathogens that are typically indispensable for their survival. For this reason, MAMPs cannot be mutated or removed without causing pathogen death. However, this does not necessitate constitutive expression of MAMPs. In this study, the MAMP response of Arabidopsis thaliana was utilized to determine differential detection of MAMPs expressed by Pseudomonas syringe pv. tomato DC3000 when pretreated with A. thaliana. Results demonstrated that more MAMPs are detected when P. syringae had previously encountered A. thaliana, …
