Public and Environmental Health MicrobiologyChlortetracycline Enhances Tonsil Colonization and Fecal Shedding of Multidrug-Resistant Salmonella enterica Serovar Typhimurium DT104 without Major Alterations to the Porcine Tonsillar and Intestinal MicrobiotaSalmonella spp. are an important cause of foodborne illness in North America, and pork products are associated with sporadic cases and outbreaks of human salmonellosis. Isolates of Salmonella may be resistant to multiple antibiotics, and infections with multidrug-resistant (MDR) Salmonella spp. are more difficult to treat, leading to increased...
Food Microbiology | SpotlightHigh-Resolution Identification of Multiple Salmonella Serovars in a Single Sample by Using CRISPR-SeroSeqSalmonella enterica is the leading bacterial cause of foodborne illness in the United States and is represented by over 2,600 distinct serovars. Some of these serovars are pathogenic in humans, while others are not. Current surveillance for this pathogen is limited by the detection of only the most abundant serovars, due to the culture-based approaches that are used....
Public and Environmental Health MicrobiologyAlterations of Salmonella enterica Serovar Typhimurium Antibiotic Resistance under Environmental PressureAntibiotic resistance is attributed to the misuse or overuse of antibiotics in agriculture, and antibiotic resistance genes can also be transferred to bacteria under environmental stress. In this study, we report a unidirectional alteration in antibiotic resistance from susceptibility to increased resistance. Highly sensitive Salmonella enterica serovar Typhimurium...
- PhysiologyiTRAQ-Based Global Proteomic Analysis of Salmonella enterica Serovar Typhimurium in Response to Desiccation, Low Water Activity, and Thermal Treatment
Salmonella enterica is able to survive in dry environments for very long periods. While it is well known that the initial exposure to desiccation is fundamental to trigger thermal tolerance in this organism, the specific physiological and molecular processes involved in this cross-protection phenomenon have not been fully characterized. Several studies have focused on...
