The degree of genetic diversity in 45 Bordetella (B.) bronchiseptica strains comprised of a vaccine strain (N = 1), reference strains (N = 3) and field isolates (N = 41) was evaluated using random amplified polymorphic DNA (RAPD) fingerprinting and pulsed-field gel electrophoresis (PFGE). Three candidate primers were selected for RAPD analysis after screening 20 random decamer oligonucleotides ...

Background: Occupational physical activity (OPA) is prevalent in the general population. However, its influence on the health status of manual workers is unclear. This study examined the impact of OPA on the health-related quality of life (HRQoL) of vocational-skilled workers (VSWs) in Nigeria.  Materials and Methods: This cross-sectional study was conducted on 354 male VSWs from six cities in...

Bacterial wilt, caused by Ralstonia solanacearum E.F. Smith, is one of the most destructive diseases of tomato (Lycopersicon esculentum Mill) in Sri Lanka. Twenty isolates of R. solanacearum from tomato plants grown in eleven different agro climatic zones from selected districts (Kandy, Matale, Monaragala) were characterized in terms of pathogenicity on susceptible check variety Marglobe and in...

the one photon absorption (opa) cross section of a current carrying two-orbital quantum dot (qd) with strong electron-phonon interaction (polaron regime) is considered. using the self-consistent non-equilibrium hartree-fock (hf) approximation, we determine the dependence of opa cross section on the applied bias voltage, the strength of effective electron-electron interaction, and level spacing ...

We investigated the role of gonococcal outer membrane protein PII (also called Opa protein) in nonopsonic adherence to human neutrophils. Gonococcal outer membranes, purified Opa in detergent (Opa), purified Opa in liposomes (Opa+ lips), and peptides composing the second hypervariable (HV2) region of OpaB (strain FA1090) in liposomes (pepHV2 lips) were tested for their abilities to inhibit subs...

Soybean (Glycine max L.) is an important crop plant which contains a high amount of oil and protein. The main goal the work was to use 13 RAPD (Random Amplified Polymorphic DNA) markers study genetic polymorphism in set 28 soybean genotypes construct dendrogram from obtained results, based on we will recommend for further breeding. In total, using markers, determined 108 fragments with average ...

T cells may interact with a number of bacterial surface antigens, an encounter which has the potential to downmodulate host immune responses. Neisseria meningitidis, a human colonizer and an agent of septicemia and meningitis, expresses Opa proteins which interact with the CEACAM1 receptor expressed on activated T cells. Since CEACAM1 can act as an inhibitory receptor and T cells in subepitheli...

The opacity (Opa) proteins of Neisseria gonorrhoeae are a family of outer membrane proteins demonstrating phase and antigenic variation. N. gonorrhoeae strain FA0190 has 11 opa loci that encode at least 8 antigenically distinct Opa proteins. To determine if expression of one Opa protein or a subset of them is favored during gonococcal infection, we inoculated Opa-negative variants of strain FA1...
