Cryptosporidium Genomics – Current Understanding, Advances, and Applications

Donna Huber on May 31, 2024

Purpose of review: Here we highlight the significant contribution that genomics-based approaches have had on the field of Cryptosporidium research and the insights these approaches have generated into Cryptosporidium biology and transmission. Recent findings: There are advances in genomics, genetic manipulation, gene expression, and single-cell technologies. New and better genome sequences have revealed variable sub-telomeric …

Temporal gene expression during asexual development of the apicomplexan Sarcocystis neurona

Donna Huber on May 29, 2024

Asexual replication in the apicomplexan Sarcocystis neurona involves two main developmental stages: the motile extracellular merozoite and the sessile intracellular schizont. Merozoites invade host cells and transform into schizonts that undergo replication via endopolygeny to form multiple (64) daughter merozoites that are invasive to new host cells. Given that the capabilities of the merozoite vary …

What is new in FungiDB: a web-based bioinformatics platform for omics-scale data analysis for fungal and oomycete species

Donna Huber on March 26, 2024

FungiDB (https://fungidb.org) serves as a valuable online resource that seamlessly integrates genomic and related large-scale data for a wide range of fungal and oomycete species. As an integral part of the VEuPathDB Bioinformatics Resource Center (https://veupathdb.org), FungiDB continually integrates both published and unpublished data addressing various aspects of fungal biology. Established in early 2011, …

Genomic and virulence analysis of in vitro cultured Cryptosporidium parvum

Donna Huber on February 28, 2024

Recent advances in the in vitro cultivation of Cryptosporidium parvum using hollow fiber bioreactor technology (HFB) have permitted continuous growth of parasites that complete all life cycle stages. The method provides access to all stages of the parasite and provides a method for non-animal production of oocysts for use in clinical trials. Here we …

Genetic crosses within and between species of Cryptosporidium

Donna Huber on January 2, 2024

Parasites and their hosts are engaged in reciprocal coevolution that balances competing mechanisms of virulence, resistance, and evasion. This often leads to host specificity, but genomic reassortment between different strains can enable parasites to jump host barriers and conquer new niches. In the apicomplexan parasite Cryptosporidium, genetic exchange has been hypothesized to play a prominent role …

VEuPathDB: the eukaryotic pathogen, vector and host bioinformatics resource center in 2023

Donna Huber on November 11, 2023

The Eukaryotic Pathogen, Vector and Host Informatics Resource (VEuPathDB, https://veupathdb.org) is a Bioinformatics Resource Center funded by the National Institutes of Health with additional funding from the Wellcome Trust. VEuPathDB supports >600 organisms that comprise invertebrate vectors, eukaryotic pathogens (protists and fungi) and relevant free-living or non-pathogenic species or hosts. Since 2004, VEuPathDB has analyzed …

Massive invasion of organellar DNA drives nuclear genome evolution in Toxoplasma

Donna Huber on November 2, 2023

Toxoplasma gondii is a zoonotic protist pathogen that infects up to one third of the human population. This apicomplexan parasite contains three genome sequences: nuclear (65 Mb); plastid organellar, ptDNA (35 kb); and mitochondrial organellar, mtDNA (5.9 kb of non-repetitive sequence). We find that the nuclear genome contains a significant amount of NUMTs (nuclear integrants …

All the pieces matter: UGA researchers collaborate to solve malaria puzzle

Super-resolution microscopy showing malaria parasites infecting human red blood cells. credit: Muthugapatti Kandasamy, Biomedical Microscopy Core They say what doesn’t kill you makes you stronger. Whoever coined that adage had probably never heard of Plasmodium. It’s a microscopic parasite, invisible to the naked eye but common in tropical and subtropical regions throughout the world. Each …

TriTrypDB: An integrated functional genomics resource for kinetoplastida

Donna Huber on January 19, 2023

Parasitic diseases caused by kinetoplastid parasites are a burden to public health throughout tropical and subtropical regions of the world. TriTrypDB (https://tritrypdb.org) is a free online resource for data mining of genomic and functional data from these kinetoplastid parasites and is part of the VEuPathDB Bioinformatics Resource Center (https://veupathdb.org). As of release 59, TriTrypDB hosts …
