La insuficiencia cardiaca (IC) es sin duda uno de los problemas médicos, y no solo cardiológicos, más relevantes a los que nos enfrentamos en la actualidad, sobre todo debido al aumento de la esperanza de vida de la población y el mejor tratamiento de los procesos cardiovasculares agudos. Debido a ello, la prevalencia de la IC va en aumento; en España alcanza tasas del 4-7%, y es la principal c...

Helicobacter pylori (H. pylori) infection has been reported in more than half of the world human population. It is associated with gastric inflammation and noticeable infiltration of the immune cells to the stomach mucosa by several cytokines secretion. IL-1&beta, IL-18 have been shown to contribute to H. pylori induced gastritis, but the details of inflammation and association of virulence fac...

Background: The aim of this study was to determine the prevalence of virulence-associated genes and enterobacterial repetitive intergenic consensus PCR (ERIC-PCR) analysis of Campylobacter spp. isolated from children with diarrhea in Iran. Methods: A total of 200 stool specimens were obtained from children under 5 years during July 2012 to July 2013. Detection of C. jejuni and C. coli was perfo...

background and objectives: brucella, causative of brucellosis, has some potential virulence factors involved in brucella replication and its strategies to circumvent the immune response. one of them is the virb gene that encodes the type іv secretion system proteins (t4ss) involved in intracellular replication of organism. brucella virulence factor a ( bvf a), and urease ( ure ) has also been d...

background: avian pathogenic escherichia coli (apec), which is the causative agent of colibacillosis, harbors several putative virulence genes. an important trait of apec for both poultry and public health is antibiotic resistance. objectives: in the present study, some potential virulence genes of apecs isolated from northeast of iran and their resistance to the quinolones antibiotics were stu...

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...

Pasteurella multocida possesses various virulence factors, including capsule, lipopolysaccharide, fimbriae, toxins, outer membrane proteins, and adhesions. Adhesins have a crucial role in mediating colonization and invasion of the host. The aim of the present study was to identify the prevalence of adhesion factor genes and resistance/sensitivity patterns among the avian P. multocida isolates f...

Objective: Considering the emergence of biofilm-associated pathogens with multidrug resistance, the objective(s) of the present study was to evaluate the anti-virulence property of Syzygium aromaticum extracts/fractions against 2 multidrug-resistant catheter isolates. Materials and Methods: Pulverized clove buds were subjected to bioactivity-guided isolation to identify the bioactive extract/fr...
