Awesome Parasite Awesome

A curated list of amazingly awesome information and open-access databases related to parasites and host-pathogen interactions.

Parasites are unique organisms studied in a variety of disciplines due to their health burden, diversity, and complex ecologies.

Awesome parasite was created by Anna Willoughby and is maintained in partnership with EcoHealth Alliance. Contributions welcome, please read the contributing guidelines.

  • Arctos - A collective management database for museum specimens. See below for specific collections. Data includes locality and collection dates, and is downloadable for any registered accounts.
  • Benesh et al. 2017, Ecology - Extensive database with 8,510 host species associations of parasites with complex life cycles (acanthocephalans, cestodes, and nematodes). Includes life‐history data such as development time and body size for each life cycle stage of the parasites.
  • ENHanCEd Infectious Diseases Database (EID2) - A database that pulls organism associations from NCBI sequences and PubMed. See database and brief analysis in Wardeh et al. 2015.
  • Global Biotic Interactions (GloBI) - A species interaction repository that can be searched by 'parasite of', 'pathogen of', or 'host of'.
  • Global Mammal Parasite Database 2.0 - A database of the parasites of wild ungulates (artiodactyls and perissodactyls), carnivores, and primates.
  • Human Virus Database (HVD) - A database of human viruses, including information on infected tissues. See description and use in a predictive model in Ye et al. 2022
  • Interaction Web Data (iwdb) - Collation of fish host and parasites datasets from several Canadain liminological sites, including information on prevalence and intensity. Part of a larger database of species interactions in food webs and plant relationships originally developed in 2003 by NCEAS and is now hosted by the Department of Ecology at the University of São Paulo, Brazil.
  • MalAvi - A database of avian blood parasites from the Plasmodium, Haemoproteus and Leucocytozoon genera including select host and vector information. See database description by Bensch et al. 2009.
  • NHM Host-parasite database - A database of parasitic worms extracted from the scientific literature maintained by London Natural History Museum. Compilation started in 1922 by Dr H.A. Baylis, with curation through 2003 by LNHM staff. Wells et al. 2018 provides a broad analysis of this database, and you can access data through the R package helminthR.
  • Olival et al. 2017, Nature - Mammal-virus database with analysis.
  • PEARL - Conservation assessments of macroparasitic invertebrates.
  • PHI-base - A database with information on specific genes of fungal, Oomycete and bacterial pathogens that affect pathogenicity. Focused on agricultural and medical pathogens of importance.
  • PREDICT - Field data from the USAID PREDICT project 2008-2019, a global emerging virus surveillance program. This data is downloadable if you have a healthmap account.
  • Shaw et al. 2020 - A human-curated database of 12,212 host-pathogen associations: 2,595 bacterial and viral pathogens infecting 2,656 vertebrate host species across 90 host orders. It also contains a mitochondrial genome phylogeny for the host species. Analysis published in Molecular Ecology.
  • Virus-Host DB - A synthesis of host-virus associations from genomes posted in NCBI/RefSeq and GenBank.
  • Web of Life - An aggregated resource and graphical user interface for easily visualizing and downloading data on ecological networks, including host-parasite interactions. As of January 2024, the host-parasite communities are exclusively gleaned from Hadfield et al. 2013 whose original data files are provided on Dryad.
  • Zover - A conglomeration of the previous bat (DBatVir) and rodent virus (DRodVir) databases with the addition of mosquito- and tick- borne viruses. Database is described here.

Museums & Collections

Citizen Science Projects

  • Garden Wildlife Health - This is a UK collaborative project between the Zoological Society of London (ZSL), the British Trust for Ornithology (BTO), Froglife and the Royal Society for the Protection of Birds (RSPB) that historically has been running since the 1980's (previously as Garden Bird Health initiative and Frog Mortality Project). Citizens can submit sickness and mortality reports, as well as animal wildlife samples, for wild birds, amphibians, reptiles, and hedgehogs.
  • Project Monarch Health - A citizen science project running since 2006 to test adult monarch butterflies from the U.S. and Canada for the protozoan parasite Ophryocystis elektroscirrha. Participants submit spore samples collected from adult abdomems with tape for laboratory assessment at University of Georgia.

Reporting Systems

  • EMPRES-i+ Global Animal Disease Information System - A web platform maintained by FAO that provides geolocated data on animal diseases such as rabies, foot-and-mouth disease, or MERS coronavirus. This is a tracking service in which countries and veterinarians can opt-in to reporting.
  • Healthmap - A web platform that provides infectious disease outbreak alerts for humans and animals.
  • NORS - A web platform that provides human foodborne, waterborne, and other enteric infectious disease outbreaks for the United States. Available from 1971.
  • Program for Monitoring Emerging Diseases (ProMed) - An early warning of outbreaks of emerging and re-emerging diseases. Sources of information include media reports, official reports, online summaries, local observers, and others. EIDR-Connect parses ProMed reports into disease outbreak events, curated by disease experts.
  • The Contagion Outbreak Monitor - An interactive map of human bloodborne or foodborne outbreaks in the past two years. Targeted to practitioners and clinicians.
  • WHISPers - Wildlife Health Information Sharing Partnership event reporting system managed by USGS National Wildlife Health Center. Events of North American wildlife mortality (death) and morbidity (illness) involving five or more individuals are reported.
  • World Animal Health Information System (WAHIS) - The OIE archive of country alerts and regular reports of certain pathogens. They also have some nice interfaces to show disease distribution and timelines.
