In silico and empirical analyses of the evolution and activity of diverse AB5 toxins found within the Salmonella genus
DownloadFall 2023
Bacterial AB5 toxins are secreted protein complexes composed of an enzymatic A subunit that disrupts host cell functions and a pentameric B subunit that facilitates cellular entry of the toxin by binding to specific cell surface receptors. AB5 toxins are widely recognized for their roles in the...

Inactivation of Salmonella spp. in wheat flour by 395 nm pulsed light emitting diode (LED) treatment and the related functional and structural changes of gluten
Download2020-01-01
Du, Lihui, Prasad, Amritha Jaya, Gänzle, Michael G., Roopesh, M.S.
Salmonella spp. is one of the top foodborne pathogens associated with low-moisture foods and they exhibit significant resistance to conventional thermal treatments. UV light pulses emitted from light emitting diode (LED) has shown antimicrobial potential in high-moisture foods and water. However,...

Influence of water activity on thermal resistance of microorganisms in low-moisture foods: A review
Download2016-01-01
Syamaladevi, Roopesh M., Tang, Juming, Villa-Rojas, Rossana, Sablani, Shyam S., Carter, Brady, Campbell, Gaylon
A number of recent outbreaks related to pathogens in low-moisture foods have created urgency for studies to understand the possible causes and identify potential treatments to improve low-moisture food safety. Thermal processing holds the potential to eliminate pathogens such as Salmonella in...

Influence of Water Activity on Thermal Resistance of Salmonella enterica and Quality changes in Low-moisture Foods
DownloadSpring 2019
Low-moisture foods (with aw < 0.85) including pet foods and black pepper powder have been associated with major recalls due to contamination by Salmonella spp. Increased thermal resistance and prolonged survival at low-moisture conditions are major challenges to achieve effective inactivation of...

Integration of Nanomechanical Resonators in Microfluidic Systems for Specific Protein Detection
DownloadFall 2009
Nanomechanical resonators offer a pathway towards highly sensitive and label-free detection of biomolecules by transducing the mass of bound analytes into resonant frequency shifts. Zeptogram level and even single cell detections have been successfully achieved by others. However, these...

Lethality of high-pressure carbon dioxide on Shiga toxin-producing Escherichia coli, Salmonella and surrogate organisms on beef jerky
Download2020-05-16
Schultze, Danielle M., Couto, Ricardo, Temelli, Feral, McMullen, Lynn M., Gänzle, Michael G.
Low water activity (aW) foods permit the survival of low-infectious dose pathogens including Escherichia coli and Salmonella. Desiccation of non-heat resistant E. coli and Salmonella enterica increases their heat resistance; therefore, alternative methods are necessary to ensure the safety of low...

Microbiological quality of organic vegetables produced in soil treated with different types of manure and mineral fertilizer
Download2006
Maia, Carla M., Carvalho, Isabel D., Serafini, Álvaro B., da Silva, Natan F., André, Maria C. P. B., Machado, Débora C.
An attempt was made to evaluate microbiological quality of horticultural crops grown organically. Three species of vegetables were used, lettuce (Lactuva sativa), radish (Raphanus sativus) and spinach (Tetragonia expansa), grown organically, in fertile soil. Six different treatments were applied:...

MicroRNA Buffering and Altered Variance of Gene Expression in Response to Salmonella Infection
Download2014
Plastow, G. S., Bao, H., Kommadath, A., Guan, L. L., Tuggle, C. K., Stothard, P.
One potential role of miRNAs is to buffer variation in gene expression, although conflicting results have been reported. To investigate the buffering role of miRNAs in response to Salmonella infection in pigs, we sequenced miRNA and mRNA in whole blood from 15 pig samples before and after...

Neonatal Exposure to Amoxicillin Alters Long-Term Immune Response Despite Transient Effects on Gut-Microbiota in Piglets
Download2019-01-01
Fouhse, Janelle M., Yang, Kaiyuan, More-Bayona, Juan, Gao, Yanhua, Goruk, Susan, Plastow, Graham, Field, Catherine J., Barreda, Daniel R., Willing, Benjamin P.
Antibiotic exposure during neonatal development may result in transient or persistent alterations of key microbes that are vital for normal development of local and systemic immunity, potentially impairing immune competence later in life. To further elucidate the relationship between antibiotic...

Neutrophil elastase alters the murine gut mirobiota resulting in enhanced Salmonella colonization
Download2012
Hartmann, Martin, Sekirov, Inna, Finlay, B. Brett, Al-Zahrani, Fatimah, Willing, Benjamin P., Ferreira, Rosana B. R., Gill, Navkiran, Antunes, L. Caetano M.
The intestinal microbiota has been found to play a central role in the colonization of Salmonella enterica serovar Typhimurium in the gastrointestinal tract. In this study, we present a novel process through which Salmonella benefit from inflammatory induced changes in the microbiota in order to...
