Project description:Vibrio vulnificus is a marine zoonotic pathogen associated with fish farms that is considered a biomarker of climate change. Zoonotic strains trigger a rapid death of their susceptible hosts (fish or humans) by septicemia that has been linked to a cytokine storm in mice. A toxin called RtxA1 produced by the bacteria might play an important role in bacterial invasion and subsequent death by septic shock since animals infected with a mutant deficient in rtxA1 suffer from septicemia but do not die. The aim of this study was to globally analyze the early eel immune response in blood against V. vulnificus, as well as the role of the RtxA1 toxin on this interaction.
Project description:Differential expression was determined in Calu-3 cells between mock infected and infection with NS1trunc124: A/Vietnam/1203-CIP048_RG4/2004 (H5N1) or WT: A/Vietnam/1203/2004 (H5N1) at different times post infection.
Project description:The present study examines changes in global gene expression patterns and in virulence factor-associated genes in an extended spectrum beta-lactamase (ESBL)-producing UPEC (ESBL019) during the morphologic transitions induced by an ineffective antibiotic and in the presence of human primary bladder epithelial cells. The morphological shifts induced by ineffective antibiotics are associated with significant transcriptional virulence alterations in ESBL-producing UPEC, which may affect survival and persistence in the urinary tract.
Project description:A/Vietnam/1203-CIP048_RG3/2004 (H5N1) is a PB1-F2 deletion in wild type A/Vietnam/1203/2004 (H5N1). The goal of this study was to determine the host response (C57BL/6 mouse model) to the PB1-F2 mutation at a 10^4 PFU dose.
