    Division of Parasitic Diseases and Malaria, Centers for Disease Control and Prevention, Atlanta, Georgia, United States of America.
    Background: During the past 20 years, enormous efforts have been expended globally to eliminate lymphatic filariasis (LF) through mass drug administration (MDA). However, small endemic foci (microfoci) of LF may threaten the presumed inevitable decline of infections after MDA cessation. We conducted microsimulation modeling to assess the ability of different types of surveillance to identify microfoci in these settings. Read More

    Measuring changes in transmission of neglected tropical diseases, malaria, and enteric pathogens from quantitative antibody levels.
    PLoS Negl Trop Dis 2017 May 19;11(5):e0005616. Epub 2017 May 19.
    Division of Parasitic Diseases and Malaria, United States Centers for Disease Control and Prevention, Atlanta, Georgia, United States of America.
    Background: Serological antibody levels are a sensitive marker of pathogen exposure, and advances in multiplex assays have created enormous potential for large-scale, integrated infectious disease surveillance. Most methods to analyze antibody measurements reduce quantitative antibody levels to seropositive and seronegative groups, but this can be difficult for many pathogens and may provide lower resolution information than quantitative levels. Analysis methods have predominantly maintained a single disease focus, yet integrated surveillance platforms would benefit from methodologies that work across diverse pathogens included in multiplex assays.

    Infect Dis Poverty 2017 May 1;6(1):52. Epub 2017 May 1.
    Centre for Neglected Tropical Diseases (CNTD), Liverpool School of Tropical Medicine, Liverpool, UK.
    It is widely known that the recent Ebola Virus Disease (EVD) in West Africa caused a serious disruption to the national health system, with many of ongoing disease focused programmes, such as mass drug administration (MDA) for onchocerciasis (ONC), lymphatic filariasis (LF) and schistosomiasis (SCH), being suspended or scaled-down. As these MDA programmes attempt to restart post-EVD it is important to understand the challenges that may be encountered. This commentary addresses the opinions of the major health sectors involved, as well as those of community members, regarding logistic needs and challenges faced as these important public health programmes consider restarting.

    Examining the role of macrolides and host immunity in combatting filarial parasites.
    Parasit Vectors 2017 Apr 14;10(1):182. Epub 2017 Apr 14.
    Boehringer Ingelheim, 3239 Satellite Boulevard, Duluth, GA, 30096, USA.
    Macrocyclic lactones (MLs), specifically the avermectins and milbemycins, are known for their effectiveness against a broad spectrum of disease-causing nematodes and arthropods in humans and animals. In most nematodes, drugs in this class induce paralysis, resulting in starvation, impaired ability to remain associated with their anatomical environment, and death of all life stages. Initially, this was also thought to be the ML mode of action against filarial nematodes, but researchers have not been able to validate these characteristic effects of immobilization/starvation of MLs in vitro, even at higher doses than are possible in vivo.

    A low technology emanator treated with the volatile pyrethroid transfluthrin confers long term protection against outdoor biting vectors of lymphatic filariasis, arboviruses and malaria.
    PLoS Negl Trop Dis 2017 Apr 7;11(4):e0005455. Epub 2017 Apr 7.
    Ifakara Health Institute, Environmental Health and Ecological Sciences Thematic Group, Coordination Office, Dar es Salaam, United Republic of Tanzania.
    Background: The vapor phase of the volatile pyrethroid transfluthrin incapacitates mosquitoes and prevents them from feeding. Although existing emanator products for delivering volatile pyrethroids protect against outdoor mosquito bites, they are too short-lived to be practical or affordable for routine use in low-income settings. New transfluthrin emanators, comprised simply of treated hessian fabric strips, have recently proven highly protective against outdoor-biting vectors of lymphatic filariasis, arboviruses and malaria, but their full protective lifespan, minimum dose requirements, and range of protection have not previously been assessed.

    Absence of a drug that kills adult filarial parasites remains the major challenge in eliminating human lymphatic filariasis (LF); the second leading cause of long-term and permanent disability. Thus, the discovery of novel antifilarial natural products with potent adulticidal activity is an urgent need. In the present study, methanol extracts of leaves, bark and winged seeds of Dipterocarpus zeylanicus (Dipterocarpaceae) were investigated for macro and microfilaricidal activity. Read More
