BACKGROUND Toxins are important Staphylococcus aureus virulence factors, but little is known about their immunogenicity during infection. Here, additional insight is generated. METHODS Serum samples from 206 S. aureus-infected patients and 201 hospital-admitted control subjects were analyzed for immunoglobulin (Ig) G binding to 20 toxins, using flow-cytometry based technology. Antibody levels...
Background: Though previous studies have investigated the roles of dysfunctional attitudes and overgeneral autobiographical memory (OGM) in depression, a few focused on relationships among attitudes, OGM, anxiety. Moreover, moderating role OGM has received limited scholarly attention. Aims: This study anxiety, as well relationship between state ...
staphylococcus spp., is a common bacteria in cattle mastitis. detection of the low number of bacteria requires a sensitive method. we used multiplex polymerase chain reaction (m-pcr) assay to detect the genes encoding sea, seb, sec toxins, that are specific in s. aureus bacteria. the gene of 23s rrna that is conserved in all staphylococcus spp., also was used. due to the stiffness and low effec...
Background: Several virulence factors have been described in pathogenesis of Staphylococcus aureus strains. Staphylococcal Enterotoxins(SEs) that is one of the most factors, are belonging to important members of bacterial superantigens. Superantigens are defined by their ability to stimulate cytokine release from both T cells and macrophages. 13 different SEs are known that their function is no...
Background and Aims: Staphylococcus aureus (S. aureus) is considered as one of the most dangerous pathogenic bacteria due to the production of extracellular toxins. The objective of this study was to determine the prevalence of S. aureus and to characterize the recovered strains for their enterotoxin-producing genes in raw cow milk. Materials and Methods: During 9 months duration of the s...
the 1rs chromosome segment derived from petkus rye carries genes for resistance to three wheat rust diseases, namely lr26 for resistance to leaf rust (caused by puccinia triticina), yr9 for resistance to stripe rust (p.striiformis f. sp. tritici) and sr31 for resistance to stem rust (p. graminis f. sp. tritici). since sec-1 is tightly linked with the three rust resis-tance genes electrophoresis...
