a social psychologic model of female adolescents' compliance with contraceptives.a theoretical model is proposed to help the clinician organize the multiple interrelationships between factors that may influence a female adolescent's compliance with her birth control method. 1 variable that has been found to be predictive for compliance in adults that was not included in the model is the quality of the patient-physician relationship. this variable was excluded because the model is a social psychological model that focuses on the attitudes and behavior of the female adolescent ...20133629018
independent origins of vectored plant pathogenic bacteria from arthropod-associated arsenophonus endosymbionts.the genus arsenophonus (gammaproteobacteria) is comprised of intracellular symbiotic bacteria that are widespread across the arthropods. these bacteria can significantly influence the ecology and life history of their hosts. for instance, arsenophonus nasoniae causes an excess of females in the progeny of parasitoid wasps by selectively killing the male embryos. other arsenophonus bacteria have been suspected to protect insect hosts from parasitoid wasps or to expand the host plant range of phyt ...201121892672

the host range of the male-killing symbiont arsenophonus nasoniae in filth fly parasitioids.the son-killer bacterium, arsenophonus nasoniae, infects nasonia vitripennis (hymenoptera: pteromalidae), a parasitic wasp that attacks filth flies. this gammaproteobacterium kills a substantial amount of male embryos produced by an infected female. aside from male death, the bacterium does not measurably affect the host, and how it is maintained in the host population is unknown. interestingly, this bacterial symbiont can be transmitted both vertically (from mother to offspring) and horizontall ...201021147118
arsenophonus nasoniae and rickettsiae infection of ixodes ricinus due to parasitic wasp ixodiphagus hookeri.arsenophonus nasoniae, a male-killing endosymbiont of chalcid wasps, was recently detected in several hard tick species. following the hypothesis that its presence in ticks may not be linked to the direct occurrence of bacteria in tick's organs, we identified a. nasoniae in wasps emerging from parasitised nymphs. we confirmed that 28.1% of ixodiphagus hookeri wasps parasitizing ixodes ricinus ticks were infected by a. nasoniae. moreover, in examined i. ricinus nymphs, a. nasoniae was detected on ...201626901622
disentangling a holobiont - recent advances and perspectives in nasonia wasps.the parasitoid wasp genus nasonia (hymenoptera: chalcidoidea) is a well-established model organism for insect development, evolutionary genetics, speciation, and symbiosis. the host-microbiota assemblage which constitutes the nasonia holobiont (a host together with all of its associated microbes) consists of viruses, two heritable bacterial symbionts and a bacterial community dominated in abundance by a few taxa in the gut. in the wild, all four nasonia species are systematically infected with t ...201627721807
characteristics of the genome of arsenophonus nasoniae, son-killer bacterium of the wasp nasonia.we report the properties of a draft genome sequence of the bacterium arsenophonus nasoniae, son-killer bacterium of nasonia vitripennis. the genome sequence data from this study are the first for a male-killing bacterium, and represent a microorganism that is unusual compared with other sequenced symbionts, in having routine vertical and horizontal transmission, two alternating hosts, and being culturable on cell-free media. the resulting sequence totals c. 3.5 mbp and is annotated to contain 33 ...201020167019
the draft genome sequence of arsenophonus nasoniae, son-killer bacterium of nasonia vitripennis, reveals genes associated with virulence and symbiosis.four percent of female nasonia vitripennis carry the son-killer bacterium arsenophonus nasoniae, a microbe with notably different biology from other inherited parasites and symbionts. in this paper, we examine a draft genome sequence of the bacterium for open reading frames (orfs), structures and pathways involved in interactions with its insect host. the genome data suggest that a. nasoniae carries multiple type iii secretion systems, and an array of toxin and virulence genes found in photorhab ...201020167018
asymmetrical brain modulation of the immune is now well known that the central nervous system can regulate the immune system. interestingly the two sides of the brain have been demonstrated to be differently involved in the modulation of immune responses. in rodents, lesions of right or left neocortex induced opposite effects on various immune parameters including mitogen-induced lymphoproliferation, interleukin-2 production, macrophage activation or natural killer cell activity. furthermore in humans, left-handedness has been reported ...20061393189
host-symbiont interactions of the primary endosymbiont of human head and body lice.the first mycetome was discovered more than 340 yr ago in the human louse. despite the remarkable biology and medical and social importance of human lice, its primary endosymbiont has eluded identification and characterization. here, we report the host-symbiont interaction of the mycetomic bacterium of the head louse pediculus humanus capitis and the body louse p. h. humanus. the endosymbiont represents a new bacterial lineage in the gamma-proteobacteria. its closest sequenced relative is arseno ...200717227954
evidence for multiple acquisition of arsenophonus by whitefly species (sternorrhyncha: aleyrodidae).whiteflies contain primary prokaryotic endosymbionts located within specialized host cells. this endosymbiotic association is the result of a single infection of the host followed by vertical transmission of the endosymbiont to the progeny. whiteflies may also be associated with other bacteria called secondary (s-) endosymbionts. the nucleotide sequence of the 16s-23s ribosomal dna from s-endosymbionts of 13 whitefly species was determined. a phylogenetic analysis of these sequences indicated th ...200415057483
