Biological Resources of the ATCC Protistology Collection

September 06, 2012, at 12:00 PM ET


Protists are eukaryotic microorganisms commonly studied due to their ecological relevance in aquatic food chains and their impact on human health. Protistology research and comparative studies are dependent on the accessibility of authenticated biological standards. To meet this need, the Protistology Collection at ATCC houses the largest and most diverse repository of protist cultures in the world. The primary role of the collection has been the acquisition, authentication, preservation, and distribution of reference strains. Characterization of deposited cultures includes a variety of tests such as viability, purity, phenotypic properties, and genotypic analysis. Additionally, over the last decade, resources within the collection have expanded to include genomic DNA. This presentation will provide an overview of biological resources available in the ATCC Protistology Collection, a discussion on the methods of characterization, benefits of depositing, current research projects, and future perspectives.

Senior Scientist, ATCC

Robert Molestina, PhD, is a Senior Scientist at ATCC. He manages the parasitic protozoa collection of BEI Resources and has served as the subject matter expert in the Protistology Laboratory overseeing the development of assays for molecular authentication of protists, optimization of culture and cryopreservation protocols, and implementation of small animal models for in vivo parasite propagation. More recent work at ATCC resulted in the development of quantitative PCR assays to detect babesiosis in blood, proteomic analysis of Babesia infection in vivo, and the development of enhanced in vitro culture systems for Cryptosporidium. His publication record over the last 15 years covers a diversity of scientific interests, including host-parasite interactions, molecular parasitology, and eukaryotic microbiology.
