The brown planthopper (BPH), Nilaparvata lugens Stål, is an insect pest that severely damages rice (Oryza sativa L.) in Asia, causing huge yield loss. Use of resistant variety a cost-effective and eco-friendly strategy for maintaining BPH populations below the economic injury level. However, current have been changed to virulence against varieties. In this study, estimate effective combinations...

The aim of this study was to investigate whether or not surgical biopsy of sinus tissue in chronic sinusitis, not responsive to treatment, would detect E. coli. We intended to evaluate E. coli virulence genes, therefore dispute the causal role of such an unusual microorganism in chronic sinusitis, as well as consider effective pathogen-targeted therapy. Patients with E. coli isolated by intra-o...

Avian pathogenic Escherichia coli (APEC) are responsible for wide ranges of extra-intestinal diseases in poultry including colibacillosis, cellulitis, coligranuloma and yolk sac infection. Numbers of virulence are considered important in the pathogenicity of these diseases. The aims of the present study were phylogenetic typing and virulence genes detection in Escherichia coli </em...

Brucellosis is a widespread zoonotic disease causing considerable economic and public health problems. Despite animal vaccination, brucellosis remains endemic in some areas such as Iran, especially in the western Iranian province of Hamadan. We sought to detect some of the most common virulence-associated genes in Brucella isolated from human blood cultures to determine the prevalence of some v...

Tumour markers are substances that are produced either by the tumour itself or by the body in response to the presence of cancer or certain benign conditions that can aid in the diagnosis of cancer. The subject of tumour markers is a broad one, and there is an abundance of data. A literature review of potential molecular markers relevant to oral neoplasia was undertaken in terms of a perspectiv...

conclusions by studying the profiles of virulence genes and mlva, it can be concluded that eiec isolates do not have high heterogeneity and are derived from a limited number of clones. background enteroinvasive escherichia coli (eiec) isolates cause dysentery in humans. several virulence factors associated with eiec pathogenesis have been characterized. multilocus variable-number tandem-repeat ...

The duodenal ulcer promoting (dupA) gene, located in the plasticity region of Helicobacter pylori, is associated with duodenal ulcer development. dupA was predicted to form a type IV secretory system (T4SS) with vir genes around dupA (dupA cluster). We investigated the prevalence of dupA and dupA clusters and clarified associations between the dupA cluster status and clinical outcomes in the U....

Orobanche cumana Wallr. (sunflower broomrape) is a holoparasitic weed that infects roots of sunflower in large areas of Europe and Asia. Two distant O. cumana gene pools have been identified in Spain, one in Cuenca province in the Center and another one in the Guadalquivir Valley in the South. Race F has been hypothesized to have arisen by separate mutational events in both gene pools. In the G...
