Genomic diversity and genomic typing of Salmonella enterica serovar Typhimurium
Salmonella enterica serovar Typhimurium (S. Typhimurium) is one of the most frequently reported serovars in Australia. In the first study of this thesis, 21 S. Typhimurium genomes from Salmonella reference collection A (SARA) were sequenced. Together with 47 publicly available S. Typhimurium …

Mechanisms of anaerobic nitric oxide detoxification by Salmonella enterica serovar Typhimurium
Salmonella is the cause of millions of food- and water-borne infections worldwide. Systemic infection and gastroenteritis are the main diseases and often prove fatal to immunocompromised patients. Key to Salmonella’s pathogenicity is the survival of several components of the innate immune system …

Fatty Acid Degradation in Escherichia Coli and Salmonella Enterica Serovar Typhimurium
Wild type strains of S. enterica grow on decanoic acid whereas wild type E. coli strains cannot. Mutant strains (fadR) of both organisms are readily isolated in which the genes (fad) of fatty acid degradation are expressed constitutively. The S. enterica fadR strains grow more rapidly than the wild …

Finding Typhoid Mary: Identifying Latent Carriers of Salmonella enterica serovar Typhimurium
Salmonella enterica serovar Typhimurium (S. Typhimurium) is an important human pathogen. The Centers for Disease Control and Prevention (CDC) estimates that 1,027,561 people become ill with nontyphoidal Salmonellosis annually, and S. Typhimurium is one of the most common disease causing serovars. …

Considerations for Automating Salmonella Serovar Identification within an Electronic Public Health Reporting Environment
… surveillance reporting include submission of serovars from the recognized naming scheme, Kauffmann-White (K-W), using identifiers curated by the Systematized Nomenclature of Medicine-Clinical Terms (SNOMED CT®). Translating the serotype formula of a Salmonella isolate to the correct identifier …

Role of Salmonella enterica subspecies enterica serovar Enteritidis pathogenicity island-2 in chickens
Salmonella enterica subspecies enterica serovar Enteritidis (S. Enteritidis) has been identified as a significant cause of salmonellosis in humans. Salmonella pathogenicity islands 1 and 2 (SPI-1 and SPI-2) each encode a specialized type III secretion system (T3SS) that enables Salmonella to …

Mode of Entry and Survival of Salmonella Enterica Serovar Typhimurium in Trophoblast Cells
Salmonella enterica species are intracellular bacteria causative agents of gastroenteritis and typhoid fever in humans. Pregnancy poses an increased risk of severe Salmonellosis in many mammalian species contributing to miscarriage and/or maternal illness. Previous studies indicated that Salmonella …

Role of Bacterial Effectors SopD and SopB in Pathogenicity of Salmonella enterica serovar Typhimurium.
Salmonella enterica serovar Typhimurium is a facultative intracellular pathogen that has evolved to take advantage of the eukaryotic host cells it inhabits during infection. It uses bacterial effectors translocated into the host cell cytosol to manipulate host cell machinery and establish a …

Ethanol Mist to Control Salmonella enterica serovar Newport on Fresh Tomato and Cantaloupe Surfaces
Water used in fresh produce washing is a potential vehicle of foodborne pathogen contamination. This work focused on assessing the sanitizing efficacy of ethanol mist to reduce Salmonella populations on the surfaces of tomatoes and cantaloupes. Ethanol (70%) mist was applied to whole tomatoes and …

The role of AcrA in the antibiotic resistance and virulence of Salmonella enterica serovar Typhimurium
AcrA is the periplasmic adaptor protein component of the major efflux system AcrB-TolC of \(Salmonella\) Typhimurium. AcrA of S. \(Typhimurium\) SL1344 was inactivated and the mutant phenotype characterised. RT-PCR and western blotting were used to confirm expression of \(acrB/AcrB\) was retained …

Mutagenic Studies of RdoA, a Eukaryotic-Like SER/THR Protein Kinase in Salmonella Enterica Serovar Typhimurium
RdoA is a eukaryotic-like serine/threonine protein kinase found in Salmonella typhimurium. It is a downstream effector of the Cpx stress response pathway and has been phenotypically characterized to have a functional role in flagellin phase variation and long-term bacterial survivability. …

OmpD but not OmpC is involved in adherence of Salmonella enterica serovar Typhimurium to human cells
<p>Salmonella enterica serovar Typhimurium expresses three major outer membrane proteins: OmpC, OmpF, and OmpD. Conflicting reports exist regarding the role of OmpC and OmpD in the pathogenesis of this organism. This study investigated the role of OmpC and OmpD in adherence to human U937 …

Endogenous production and detoxification of a potent cytotoxin, nitric oxide, in Salmonella enterica serovar Typhimurium and Escherichia coli
Salmonella serovars are harmful enteric pathogens of economical and clinical importance that possess sophisticated strategies to rapidly adapt to various host (human and animal) and non-host (soil, water and industrial) environments. Nitrosative stress, in the form of RNS such as the potent …

Deciphering Metabolic Adaptations in Salmonella Enterica Serovar Typhimurium 14028S During Batch Growth and Gentamicin Exposure Using Absolute Quantitative Proteomics
… in the food-borne pathogen Salmonella enterica serovar Typhimurium (S. Typhimurium) using data-independent acquisition (DIA) mass spectrometry (MS)-based approach. We first mapped the metabolic activities of S. Typhimurium cells throughout batch growth (early, mid, and late logarithmic and early …

Optimizing main spectrum profiles for use in real-time MALDI-TOF mass spectrometry identification of Leptospira serovars
… human and non-human animals. Over 250 pathogenic serovars of Leptospira, the causative agents of leptospirosis, have been identified. Given the proclivity for certain associations between these serovars and reservoir hosts, identification of clinical isolates to the serovar-level is key to …
