Title: High-efficiency electroporation of chytridfungi
Abstract Two species of parasitic fungi from the phylum Chytridiomycota (chytrids)are annihilating global amphibian populations. These chytrid species— Batrachochytrium dendrobatidis and B. salamandrivorans —have high rates of mortality and transmission. Uponestablishing infection in amphibians, chytrids rapidly multiply within the skin anddisrupt their hosts’ vital homeostasis mechanisms. Current disease models suggest thatchytrid fungi locate and infect their hosts during a motile, unicellular ‘zoospore’ lifestage. Moreover, other chytrid species parasitize organisms from across the tree oflife, making future epidemics in new hosts a likely possibility. Efforts to mitigate thedamage and spread of chytrid disease have been stymied by the lack of knowledge aboutbasic chytrid biology and tools with which to test molecular hypotheses about diseasemechanisms. To overcome this bottleneck, we have developed high-efficiency delivery ofmolecular payloads into chytrid zoospores using electroporation. Our electroporationprotocols result in payload delivery to between 75 and 97% of living cells of threespecies: B. dendrobatidis, B. salamandrivorans, and anon-pathogenic relative, Spizellomyces punctatus .This method lays the foundation for molecular genetic tools needed to establishecological mitigation strategies and answer broader questions in evolutionary and cellbiology.  more » « less

    ABSTRACT Amphibian populations have been declining around the world for more than five decades, and the losses continue. Although causes are complex, major contributors to these declines are two chytrid fungi, Batrachochytrium dendrobatidis and Batrachochytrium salamandrivorans , which both cause the disease termed chytridiomycosis. Previously, we showed that B. dendrobatidis impedes amphibian defenses by directly inhibiting lymphocytes in vitro and in vivo by release of soluble metabolites, including kynurenine (KYN), methylthioadenosine (MTA), and spermidine (SPD). Here, we show that B. salamandrivorans cells and cell-free supernatants also inhibit amphibian lymphocytes as well as a human T cell line. As we have shown for B. dendrobatidis , high-performance liquid chromatography (HPLC) and mass spectrometry revealed that KYN, MTA, and SPD are key metabolites found in the B. salamandrivorans supernatants. Production of inhibitory factors by B. salamandrivorans is limited to mature zoosporangia and can occur over a range of temperatures between 16°C and 26°C. Taken together, these results suggest that both pathogenic Batrachochytrium fungi have evolved similar mechanisms to inhibit lymphocytes in order to evade clearance by the amphibian immune system.

    Chytrid fungi play key ecological roles in aquatic ecosystems, and some species cause a devastating skin disease in frogs and salamanders. Additionally, chytrids occupy a unique phylogenetic position– sister to the well-studied Dikarya (the group including yeasts, sac fungi, and mushrooms) and related to animals– making chytrids useful for answering important evolutionary questions. Despite their importance, little is known about the basic cell biology of chytrids. A major barrier to understanding chytrid biology has been a lack of genetic tools with which to test molecular hypotheses. Medina and colleagues recently developed a protocol for Agrobacterium -mediated transformation of Spizellomyces punctatus . In this manuscript, we describe the general procedure including planning steps and expected results. We also provide in-depth, step-by-step protocols and video guides for performing the entirety of this transformation procedure on protocols.io (dx.doi.org/10.17504/protocols.io.x54v9dd1pg3e/v1).

    Abstract Understanding the responses of naïve communities to the invasion of multihost pathogens requires accurate estimates of susceptibility across taxa. In the Americas, the likely emergence of a second amphibian pathogenic fungus (Batrachochytrium salamandrivorans, Bsal) calls for new ways of prioritizing disease mitigation among species due to the high diversity of naïve hosts with priorB. dendrobatidis(Bd) infections. Here, we applied the concept of pathogenic potential to quantify the virulence of chytrid fungi on naïve amphibians and evaluate species for conservation efforts in the event of an outbreak. The benefit of this measure is that it combines and summarizes the variation in disease effects into a single numerical index, allowing for comparisons across species, populations or groups of individuals that may inherently exhibit differences in susceptibility. As a proof of concept, we obtained standardized responses of disease severity by performing experimental infections withBsalon five plethodontid salamanders from southeastern United States. Four out of five species carried natural infections ofBdat the start of the experiments. We showed thatBsalexhibited its highest value of pathogenic potential in a species that is already declining (Desmognathus auriculatus). We find that this index provides additional information beyond the standard measures of disease prevalence, intensity, and mortality, because it leveraged these disease parameters within each categorical group. Scientists and practitioners could use this measure to justify research, funding, trade, or conservation measures.

    ABSTRACT Planktothrix agardhii dominates the cyanobacterial harmful algal bloom community in Sandusky Bay, Lake Erie (USA), from May through September. This filamentous cyanobacterium is host to a known obligate parasite, the chytrid Rhizophydium sp. During the 2018 bloom season, by utilizing dilution and single-filament isolation techniques, 7 chytrid and 12 P. agardhii strains were isolated from Sandusky Bay. These 7 chytrids and a selection of P. agardhii hosts were then characterized with respect to infection rates. Infections by the isolated chytrids were specific to Planktothrix planktonic species and were not found on other filamentous cyanobacterial taxa present in the bay ( Aphanizomenon sp. and Cuspidothrix sp.). Even among the potential P. agardhii host strains, individual chytrid isolates had different degrees of infectivity and showed preferences for different host isolates, suggesting possible ecological partitioning even within the same sample population. When mechanisms of chytrid pathogenesis were examined, the zoospores displayed a swarming pattern to attack and fracture the host filament and create new infection sites at the trichome termini. Infections by these parasitic chytrids also led to a release of intracellular microcystin toxins from the hosts. Additionally, infections were dependent on medium type, highlighting the importance of medium choice for experimental outcomes. Media in which chytrid swarming was observed closely matched the ionic strength of the natural environment. Understanding pathogenesis by fungal parasites will assist future efforts to determine environmental factors favoring loss mechanisms for Planktothrix agardhii -dominated blooms. IMPORTANCE Whereas many studies have focused on the factors contributing to the establishment and persistence of cyanobacterial harmful algal blooms (cHABs), few studies have examined bloom pathogenesis. Chytrid fungi infect cyanobacteria and stimulate food web interactions through manipulation of previously hard-to-digest filaments and the release of nutrients to support heterotrophic microbes. Specifically, chytrids infective for filamentous Planktothrix agardhii exhibit a species-specific infection that fragments trichomes into shorter units that can be consumed more easily by grazers. Chytrid zoospores also serve as a high-quality food source for the lower food web. Understanding host-pathogen relationships and mechanisms of pathogenesis on cyanobacteria will be necessary to effectively model the ecology of cHABs.
