A validated high-throughput method for assaying rat lungworm () motility when challenged with potentially anthelmintic natural products from Hawaiian fungi.

Parasitic nematodes devastate human and animal health. The limited number of anthelmintics available is concerning, especially because of increasing drug resistance. Anthelmintics are commonly derived from natural products, e.

Guidelines for the diagnosis and treatment of neuroangiostrongyliasis: updated recommendations.

A subcommittee of the Hawaii Governor's Joint Task Force on Rat Lungworm Disease developed preliminary guidelines for the diagnosis and treatment of neuroangiostrongyliasis (NAS) in 2018 (Guidelines, 2018). This paper reviews the main points of those guidelines and provides updates in areas where our understanding of the disease has increased. The diagnosis of NAS is described, including confirmation of infection by real-time polymerase chain reaction (RTi-PCR) to detect parasite DNA in the central nervous system (CNS).

Role of Gastropod Mucus in the Transmission of Angiostrongylus cantonensis, a Potentially Serious Neurological Infection.

Angiostrongylus cantonensis, the rat lungworm, is endemic to Hawaii. A recent increase in the number of cases has drawn intense local and national media attention. As a result there is an increased fear of acquiring the disease from local produce, which has the potential to adversely affect the income of local farmers.

The role of eosinophils in angiostrongyliasis: multiple roles for a versatile cell?

Human infection with the rat lungworm, Angiostrongylus cantonensis, is characterized by a vigorous eosinophil response that gives the disease its name, eosinophilic meningitis. The actual role eosinophils play, both protective and destructive, in this infectious process is still largely a mystery. Research since 2002 has indicated that eosinophils are a multifaceted granulocyte that contributes to a wide range of physiological and pathological processes depending on their location and activation status.

Global mass spectrometry based metabolomics profiling of erythrocytes infected with Plasmodium falciparum.

Malaria is a global infectious disease that threatens the lives of millions of people. Transcriptomics, proteomics and functional genomics studies, as well as sequencing of the Plasmodium falciparum and Homo sapiens genomes, have shed new light on this host-parasite relationship. Recent advances in accurate mass measurement mass spectrometry, sophisticated data analysis software, and availability of biological pathway databases, have converged to facilitate our global, untargeted biochemical profiling study of in vitro P.

Workshop on research priorities for management and treatment of angiostrongyliasis(1).

In a concluding session of the workshop, the participants developed a list of 115 research and outreach needs, outlining the top 5-7 needs in each of 8 areas (Table). For complete information, including presenter details and abstracts, visit the workshop website at www.hawaii.

T-cell activation and cytokine production via a bispecific single-chain antibody fragment targeted to blood-stage malaria parasites.

A novel bispecific single-chain antibody fragment (biscFv) has been constructed to address the possibility of a new approach to malaria therapeutic drug development. The biscFv consists of 2 different single-chain antibody fragments linked by a flexible peptide linker (Gly(4)-Ser)(3). Of the 2 scFv fragments, one is directed against a conserved epitope of the 19-kDa C-terminal fragment of the major surface protein of human malignant malaria parasite, Plasmodium falciparum, and the other is directed against the CD3 antigen of human T cells.
