Prevalence, virulence factors and antimicrobial resistance of salmonella species from beef in retail outlets from KwaZulu-Natal province, South Africa
… serotypes are one of the leading causes of foodborne infections worldwide. Furthermore, the emergence and spread of antimicrobial-resistant Salmonellastrains is a potential global challenge. This study was aimed at determining the prevalence, serovars, virulence factors and antimicrobial …

An investigation of biosurfactant-mediated disruption and biological activity in mature biofilms formed on plastic surfaces by LPS mutants of Salmonella enterica serovar Typhimurium
… subsp. enterica serovar Typhimurium is a major foodborne pathogen. Its ability to form biofilms (a community of microorganisms) contributes to contamination in the food industry and clinical environments, posing challenges for disinfection and increasing the risk of spread. Biosurfactants, …

Investigation of molecular mechanisms of biofilm formation by <i>Listeria monocytogenes</i>
… the persistence of bacteria can lead to infections and outbreaks of foodborne diseases. Listeria monocytogenes is a Gram-positive Firmicute that causes foodborne infections. Frequently, infection is caused by ingesting food that has been contaminated in processing plants. L. monocytogenes …

Assessment of microbial quality and safety of ground beef/product sold in differrent retailers around Thohoyandou Area, Vhembe District, Limpopo
… industry. Despite the control measures in place, foodborne infections continue to be an immense problem, with millions of cases occurring annually worldwide. In South Africa, illnesses and deaths related to food consumption continue to be reported. In addition to the misery caused, the financial …

Characterisation of bacteriophage dynamics associated with foodborne pathogens
… modulating microbial communities and treating infections. However, much remains unknown about how phages behave in the gut ecosystem where microbial dynamics are complex and are influenced by host factors and acute events such as foodborne infections. This thesis explores the ecological roles …

CHARACTERISTICS OF CLINICAL NONTYPHOIDAL SALMONELLA ISOLATES FROM A HISTORICAL BIOBANK WITH A FOCUS ON THE INVASIVE SEROTYPE CHOLERAESUIS, LOMBARDY REGION (2001-2016)
… Salmonella enterica is a leading cause of foodborne infections worldwide, with clinical presentations ranging from self-limiting gastroenteritis to invasive systemic disease. While typhoidal serotypes are well recognized as agents of enteric fever, a subset of nontyphoidal serotypes also …

Structural and Mechanistic Roles of Novel Chemical Ligands on Quorum Sensing Transcription Regulator SdiA in Enterohemorrhagic Escherichia coli
… E. coli (EHEC) O157:H7. Although EHEC causes foodborne infections worldwide that result in bloody diarrhea and hemolytic uremic syndrome (HUS), cattle is the major reservoir of EHEC. In cattle, EHEC colonizes predominately at the recto-anal junction (RAJ). Colonization at the RAJ poses a …

Resistencia a beta-lactámicos y fluoroquinolonas en Salmonella enterica. Mecanismos moleculares y elementos de movilización génica
… zoonotic pathogen frequently implicated in human foodborne infections. The emergency of clinical isolates resistant to antibiotics involves serious limits for their treatments. The first objective of this thesis was to study the resistance phenotype and its relation with the serotype in 280 S. …

Disinfection of fresh produce contaminated by enteric viruses and their inactivation mechanisms
… has been identified as the major cause of foodborne viral illnesses in the United States. Viruses from contaminated irrigation water could be carried to crops, resulting in foodborne infection risks, especially for fresh produce eaten raw. Upon harvest, vegetables are commonly washed by a …

Characterization of the type VI protein secretion system encoded in the Salmonella pathogenicity island 19 and its role in the pathogenicity of serotypes Gallinarum and Enteritidis
… entre los años 1995 y 2008 (WHO Global Foodborne Infections Network Country Databank). Existen pocos trabajos realizados sobre los mecanismos moleculares detrás de la adaptación al hospedero aviar y sobre las implicancias clínicas de las infecciones causadas por los serotipos Enteritidis …
