We present crystal structures of the butenolide receptor AvaR1 in is olation, and in complex with avenolide, as well as AvaR1 bound to an oligonucleotide derived from its operator. Biochemical studies guided by the co-crystal structures enable identification of 90 new actinobacteria that may be regulated by butenolides, two of which are experimentally verified. These studies provide a foundation for understanding regulation of microbial secondary metabolite production, which may be exploited for the discovery and production of novel medicines.

(Washington University School of Medicine) Researchers at Washington University School of Medicine in St. Louis have received two grants from the National Institutes of Health (NIH) totaling more than $5 million to study two types of parasitic worm infection that cause devastating illness in millions of people worldwide. One project will focus on onchocerciasis, commonly known as river blindness. The second project will target fascioliasis, commonly found in cattle-farming operations.

Abstract Onchocerciasis is a neglected tropical disease caused by a nematode parasite, Onchocerca volvulus, and transmitted by bites of Simulium blackflies which breed near fast-flowing rivers. In humans thousands of microfilariae (immature worms) migrate to the skin and eyes where they cause pathology. Historically, much research was devoted to the serious effect of blindness, from which the disease earns its alternative name of "river blindness". Mapping the burden of onchocercal skin disease (OSD) was expedited by the development of a clinical classification and grading system which facilitated compar...

Answer toParasite Case of the Week 580:Loa loamicrofilariae. As noted by several readers, the nuclei go to the tip of the tail, the microfilariae are relatively large, and there is faint evidence of a sheath, all of which are characteristic features for this species. As I teach my students, the nuclei " flow-a flow-a " (to the tip) in Loa loa. Another memory trick from William Sears is that the nuclei go " lower and lower " in Loa loa. Take your pick for your favorite! Remember that the sheath will not always be seen. Size is a more definitive feature in differentiating Mansonella spp. from th...

ConclusionsNational programs need to regularly monitor and evaluate the performance and progress of their interventions, while envisaging the complete elimination of onchocerciasis from their territory. Factors hindering the targeted goal of interruption of parasite transmission need to be identified and remedial actions should be taken. If possible and appropriate, ATSs need to be implemented to accelerate disease elimination by 2025.

ConclusionThe culture system we have established forO.volvulus young adult worms offers a promising new platform to advance drug discovery against the human filarial parasite,O.volvulus and thus supports the continuous pursuit for effective macrofilaricidal drugs. However, thisin vitro culturing system will have to be further validated for reproducibility before it can be rolled out as a drug screen for decision making in macrofilaricide drug development programs.
