| Changes in the genetic structure of Aedes aegypti (Diptera: Culicidae) populations in Queensland, Australia, across two seasons: implications for potential mosquito releases. | Diseases transmitted by mosquitoes could be controlled if vector populations were replaced with strains that have reduced vector competency. Such a strategy is being developed for control of dengue virus which is transmitted by Aedes aegypti (L.) (Diptera: Culicidae). Mosquitoes artificially infected with the bacterium, Wolbachia pipientis Hertig, are being assessed as candidates for release at the adult stage with the aim of replacement of the wild population. Wolbachia can reduce the capacity ... | 2011 | 21936318 |

| pcr analysis for wolbachia in human and canine demodex mites. | in many skin diseases such as demodex folliculitis, rosacea- or steroid-induced rosacea demodex mites are present in abundance and are at least partially held responsible for causing these disorders. although it is known that these diseases respond well to tetracyclines, it is unclear if this is due to the antiinflammatory effects of the antibiotics or to an antibacterial effect on so far unknown bacteria within the demodex mites. as in filariasis, where the response to doxycycline can be explai ... | 2009 | 19652990 |
| diversity of bacteria associated with collembola - a cultivation-independent survey based on pcr-amplified 16s rrna genes. | the bacterial communities found in eight different soil-inhabiting microarthropod species of the class collembola (springtails) were analyzed by analysis of pcr-amplified 16s rrna genes obtained without cultivation from total dna. to characterize the bacteria associated with the parthenogenetically-reproducing folsomia candida, the almost complete 16s rrna genes were amplified with three universal primers, i.e., the forward primer f27 and the reverse primer r1492 or r1525. with the reverse prime ... | 2004 | 19712416 |
