background shiga-toxigenic escherichia coli is an important human pathogen cause of diarrhea, hemorrhagic colitis, hemolytic uremic syndrome and thrombotic thrombocytopenic purpura in humans is a significant public health. objectives the aim of this study was to determine the molecular characteristics and antimicrobial resistance properties of shiga toxigenic escherichia coli (stec) strains wit...

In vivo expression technology was used for testing Pseudomonas aeruginosa in the rat lung model of chronic infection and in a mouse model of systemic infection. Three of the eight ivi proteins found showed sequence identity to known virulence factors involved in iron acquisition via an open reading frame (called pvdI) implicated in pyoverdine biosynthesis, membrane biogenesis (FtsY), and adhesi...

Escherichia coli J96 (O4:K6) was isolated from a human pyelonephritis patient. Here, we report the draft genome sequence of E. coli J96, which contains virulence genes, including adhesion factors, alpha-hemolysins, and cytotoxic necrotizing factor. J96 infects the kidney and bladder, making it an important tool for studying E. coli pathogenesis.

Diabetic foot ulcers are recognized to be a severe complication of diabetes, increasing the risk amputation and death. The bacterial infection with virulent resistant bacteria as Proteus mirabilis greatly worsens wound may not treated conventional therapeutics. Developing new approaches target virulence can helpful conquer such infections. In current work, we evaluated anti-virulence activities...

Candidiasis are life-threatening systemic fungal diseases, especially of gastro intestinal track, skin and mucous membranes lining various body cavities like the nostrils, the mouth, the lips, the eyelids, the ears or the genital area. Due to increasing resistance of candidiasis to existing drugs, it is very important to look for new strategies helping the treatment of such fungal diseases. One...

background:urinary tract infections (utis) are the most common infectious diseases in childhood. the uropathogenic escherichia coli (upec) strains account for as much as 80% of utis. objective:from a clinical perspective, it is important to know which virulence factors and antibiotic resistance properties are present in upec strains in pediatrics. therefore, this study was carried out to invest...

Shiga toxin-producing Escherichia coli (STEC) cause hemorrhagic colitis (HC) and hemolytic uremic syndrome (HUS) in humans. Outbreaks are linked to bovine food sources. STEC O157:H7 has been responsible for the most severe outbreaks worldwide. However, non-O157 serotypes have emerged as important enteric pathogens in several countries. The main virulence factor of STEC is the production of Shig...

The virulence of fungi is dependent on multiple factors, including the immune status of patients and biological features of fungi. In particular, the virulence of Aspergillus fumigatus is due to the complex interaction among various molecules involved in thermotolerance (such as ribosomal biogenesis proteins, α-mannosyltransferase and heat shock proteins), pigment production (DHN-melanin), immu...

OBJECTIVE The bacterium Oceanimonas sp. (O. sp.) GK1 is a member of the Aeromonadaceae family and its genome represents several virulence genes involved in fish and human pathogenicity. In this original research study we aimed to identify and characterize the putative virulence factors and pathogenicity of this halotolerant marine bacterium using genome wide analysis. MATERIALS AND METHODS Th...

Helicobacter pylori (H. pylori) is a kind of chronic infectious pathogen which can cause chronic gastritis, peptic ulcer, gastric cancer and other diseases. The genetic structure of the pathogenic genes of H. pylori varies largely, which contributes to the differences in virulence among various strains, and in clinical symptoms. Virulence genes of H. pylori can be categorized into three main cl...
