Abstract
We report the major conclusions of the online open-access workshop "Computational Applications in Secondary Metabolite Discovery (CAiSMD)" that took place from 08 to 10 March 2021. Invited speakers from academia and industry and about 200 registered participants from five continents (Africa, Asia, Europe, South America, and North America) took part in the workshop. The workshop highlighted the potential applications of computational methodologies in the search for secondary metabolites (SMs) or natural products (NPs) as potential drugs and drug leads. During 3 days, the participants of this online workshop received an overview of modern computer-based approaches for exploring NP discovery in the "omics" age. The invited experts gave keynote lectures, trained participants in hands-on sessions, and held round table discussions. This was followed by oral presentations with much interaction between the speakers and the audience. Selected applicants (early-career scientists) were offered the opportunity to give oral presentations (15 min) and present posters in the form of flash presentations (5 min) upon submission of an abstract. The final program available on the workshop website ( https://caismd.indiayouth.info/ ) comprised of 4 keynote lectures (KLs), 12 oral presentations (OPs), 2 round table discussions (RTDs), and 5 hands-on sessions (HSs). This meeting report also references internet resources for computational biology in the area of secondary metabolites that are of use outside of the workshop areas and will constitute a long-term valuable source for the community. The workshop concluded with an online survey form to be completed by speakers and participants for the goal of improving any subsequent editions.

Abstract
A sensitive and specific test for the routine diagnosis of active Onchocerca infection is currently lacking. A major drawback in the development of such a test has been the paucity of knowledge of suitable parasite antigens that can serve as targets in antigen-detection assays. In the present investigation, we employed mass spectrometry, bioinformatics and molecular techniques to identify and characterize several potentially diagnostic Onchocerca antigens in the in vivo nodular fluid, which is being investigated for the first time. The majority of the 27 identified antigens lacked a secretory signal. One of them, also identified and characterized in greater detail with the aid of previously developed monoclonal antibodies (Mabs), was a dominant circulating cytoplasmic intermediate filament protein, previously identified and named, OV1CF. Although OV1CF lacks a secretory signal in its amino acid sequence and is not detected in the pure 42 h in vitro released products, it is easily detected in the in vivo nodular fluid. We conclude that these in vivo released products offer promise as diagnostics markers in onchocerciasis.
