Trends in the Incidence of Culture-Confirmed Human Salmonellosis Reported in Virginia During 2012-2022
… established disease reduction goals for salmonellosis incidence. Surveillance data are used to monitor progress toward these goals, and to characterize salmonellosis epidemiology (e.g., specific serotype causing disease, model national and regional trends in incidence). This study used …

Disease Surveillance and Implications on Public Health Decisions: Example of invasive Salmonellosis in sub-Saharan Africa
… the epidemiology and transmission of invasive Salmonellosis, particularly iNTS disease, evaluates trends identified through the now over 10 year running surveillance, including potential relationships with other pathogens (i.e., *Plasmodium falciparum* malaria and COVID-19), and eventually …

Risk Analysis Based on Performance Criteria: A Food Safety Control System and Decision-making Tool to Control Salmonella from Whole Broilers
… were followed to analyze the risk of acquiring salmonellosis from whole broiler (meat chickens) consumption within the United States. At the first stage, the risk of Salmonella on whole broilers was quantitatively estimated by attributing reported annual salmonellosis to whole broilers. A …

The role of the inositol phosphatase, SHIP, in the innate immune response to Salmonella Typhimurium
… unknown. Salmonella enterica causes human salmonellosis, a disease that ranges in severity from mild gastroenteritis to severe systemic illness, resulting in significant morbidity and mortality worldwide. The focus of this work was to determine the role of SHIP in a murine model of systemic …

Finding Typhoid Mary: Identifying Latent Carriers of Salmonella enterica serovar Typhimurium
… 1,027,561 people become ill with nontyphoidal Salmonellosis annually, and S. Typhimurium is one of the most common disease causing serovars. Quantification of the true number of cases of salmonellosis is hampered by the presence of a carrier state. These carriers are animals and humans that …

CHARACTERISTICS OF CLINICAL NONTYPHOIDAL SALMONELLA ISOLATES FROM A HISTORICAL BIOBANK WITH A FOCUS ON THE INVASIVE SEROTYPE CHOLERAESUIS, LOMBARDY REGION (2001-2016)
… demographic data corresponding to the related salmonellosis case. Furthermore, this thesis sought to better characterize the burden of invasive Salmonella serotypes in Lombardy, with a specific focus on S. Choleraesuis, a swine-adapted yet highly invasive human pathogen. Materials and Methods. …

Power in numbers: quantitative microbial risk assessments of Salmonella in federally sampled ground meat products and the resulting impact of risk management strategies on public health
Salmonellosis is the most common bacterial foodborne illness in the United States, and it is estimated that more than 40% of annual illnesses are attributable to the consumption of contaminated meat products. Incidence rates have not declined over the last 15 years in the US despite a significant …

Molecular basis of NAIP/NLRC4 inflammasome activation by flagellin
… to the host protective immune response against salmonellosis. Inflammasomes are multi-protein complexes formed in response to the activation of pattern recognition receptors (PRRs). The NOD-like receptor (NLR)-family of inflammasome complexes are formed from the cytosolic NLR receptors, ASC …

Correlation of Environmental Temperature, Precipitation, and Humidity with Salmonella Culture Results from Cattle in Virginia
… of weather conditions and the diagnosis of salmonellosis in cattle. Spearman's correlation coefficients were calculated for the correlations between the monthly number of samples positive for salmonella culture and weather parameters: temperature, precipitation, and relative humidity. …

Effects of Cavitation on the Removal and Inactivation of Listeria and Salmonella from the Surface of Tomatoes and Cantaloupe
… cause human illnesses, including listeriosis and salmonellosis. Microbial pathogens may attach and form biofilms on raw fruit surfaces and can be difficult to remove. A cavitation process (formation of bubbles in water) was studied for its effectiveness for removal and inactivation of Listeria …

Impacts of inoculation strategy on survival of Salmonella enterica and Enterococcus faecium at low water activity on dry peppercorn and cumin seeds
… the food industry due to increased frequency of salmonellosis outbreaks and detection-based product recalls. The impact of inoculation preparation on the survival of a Salmonella enterica and its proposed surrogate, Enterococcus faecium NRRL B-2385, on the whole black peppercorns and cumin seeds …

Association of Salmonella enterica serotype Newport with Tomato Plants through Irrigation Water, Grown under Controlled Environmental Conditions
… have been associated with numerous outbreaks of salmonellosis in recent years. Trace back suggests tomato fruit may become contaminated during pre-harvest, however exact routes are unclear. The objective of this study was to determine the potential for Salmonella enterica serotype Newport to be …

Investigating the potential of Sodium Butyrate to Control Salmonella Enteritidis in Poultry
… post-harvest intervention strategies to reduce Salmonellosis, SE infection is still an extensive problem in the poultry industry with increased incidences since SE has developed multiple strategies to adapt in the chicken intestinal tract particularly in the ceca. Therefore, reducing SE in the …

Mode of Entry and Survival of Salmonella Enterica Serovar Typhimurium in Trophoblast Cells
… Pregnancy poses an increased risk of severe Salmonellosis in many mammalian species contributing to miscarriage and/or maternal illness. Previous studies indicated that Salmonella infection in pregnant mice caused rapid fetal and maternal death due to massive bacterial proliferation in the …

An integrated approach to ciprofloxacin susceptibility analysis and high-throughput bacterial phenotyping in Salmonella
… are responsible for much of the burden of salmonellosis in sub-Saharan Africa. In recent years, there has been a drastic rise in multidrug resistance within this lineage, including fluoroquinolone resistance, a first line antimicrobial against invasive Salmonella species. In this thesis, I …

High Hydrostatic Pressure Processing Reduces Salmonella enterica from Diced and Whole Tomatoes
… have been associated with numerous outbreaks of salmonellosis in recent years. While the exact routes of contamination are unknown, high pressure processing (HPP) is being evaluated as a post harvest treatment to eliminate Salmonella enterica from tomatoes. The objectives of the study were to …

The Potential Interaction of Salmonella enterica and Ralstonia solanacearum in Tomato Plants
… been implicated in at least four outbreaks of Salmonellosis associated with tomato all originating from the same strain, Salmonella enterica serovar Newport. In addition to S. Newport contamination, the devastating plant disease, bacterial wilt, caused by the phytopathogen Ralstonia …

The role of wzz genes in Salmonella typhimurium virulence.
… for food-borne enteritis and systemic fever. Salmonellosis continues to be a serious health burden worldwide. Lipopolysaccharide (LPS) is the dominant lipid component of the outer membrane of Salmonella. LPS is composed of lipid A, an oligosaccharide core, and a polymer of O units known as O …

The Structural and Biochemical Characterization of Salmonella Host Specificity Determinant Gifsy-2 Gene E
… an estimated 93.8 million cases of non-typhoidal salmonellosis and 21 million cases of typhoid fever worldwide each year. There are thousands of Salmonella enterica serovars, some with a very specific host set, and others that cause disease in rodents, birds, livestock, domestic fowl, and humans …

Isolation of Bacterial pathogens from dead- in- shell Chicken embryos from local Hatcheries
… as a prophylactic measure to diseases like Salmonellosis and to boost production. The enforcement of legislature regulating the use of antibiotics hasn't been effectively done. This may partly explain the high levels of antimicrobial resistance observed in this limited study. The presence of …
