J Invertebr Pathol 2019; 169:107304. [PMID: 31816303 DOI: 10.1016/j.jip.2019.107304] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2019] [Revised: 12/03/2019] [Accepted: 12/05/2019] [Indexed: 12/29/2022]
Abstract
Perkinsus marinus, a World Organisation for Animal Health (OIE) notifiable parasite, infects several species of oyster, including Crassostrea virginica and Crassostrea corteziensis. There is little information on possible treatments for this parasite, but the biocidal properties of silver nanoparticles (AgNP) suggest their potential use. The lethal effects of the Argovit™ formulation of AgNP was evaluated for the first time against hypnospores of P. marinus, a particularly resistant stage of the parasite that persists in the environment until favorable conditions occur for zoosporulation to be induced. Hypnospores were exposed to 1, 10 and 100 µg/mL of silver compounded in Argovit™ (corresponding to 0.009, 0.093 and 0.927 mM of Ag), to 157.47 µg/mL (0.927 mM) of silver nitrate (AgNO3) used as a positive control, and to polyvinylpyrrolidone (PVP, 1570 µg/mL) used as a vehicle control. Hypnospores in culture medium without treatment served as a negative control. Dose-dependence after 24 h of exposure to AgNP was observed. A concentration of 0.093 mM AgNP resulted in 50% mortality of P. marinus. Treatment with 0.927 mM of silver, as AgNP or AgNO3, was highly lethal, with greater than 90% mortality. Silver nanoparticles were implicated in the deformation of hypnospores. Transmission electron microscopy (TEM) revealed AgNP within the hypnospore wall and involved in the degradation of lipid droplets in the cytoplasm. AgNP were effective in a saline medium, suggesting the utility of detailed studies of the physicochemical interactions of AgNP under these conditions. These results suggest investigations of possible effect of Argovit™ formulation of AgNP against stages of the parasite like trophozoites and tomonts that develop in tissues or hemolymph of infected oysters as well as studies on its effects in the host and environment.

Abstract
In this study, a multiplex RT-PCR-ELISA was developed to detect and differentiate four tospovirus species found in Thailand, namely Capsicum chlorosis virus (CaCV), Melon yellow spot virus (MYSV), Tomato necrotic ringspot virus (TNRV), and Watermelon silver mottle virus (WSMoV). In this system, nucleocapsid (N) gene fragments of four tospoviruses were simultaneously amplified and labeled with digoxigenin (DIG) in a single RT-PCR reaction using a pair of degenerate primers binding to the same conserved regions in all four tospovirus N genes. The DIG-labeled amplicons were distinguished into species by four parallel hybridizations to species-specific biotinylated probes in streptavidin-coated microtiter wells followed by ELISA detection using a peroxidase-conjugated anti-DIG antibody. Results indicated that the multiplex RT-PCR-ELISA assay could specifically identify each of these four tospoviruses without cross-reactivity between species or reactivity to healthy plant negative controls. Assay sensitivity was 10- to 1000-fold higher than conventional RT-PCR. When applied to naturally infected plants, all samples yielded concordant results between RT-PCR-ELISA and the reference RT-PCR. In conclusion, the multiplex RT-PCR-ELISA developed in this study has superior specificity, sensitivity, and high-throughput capacity compared to conventional RT-PCR and is an attractive alternative for the identification of different tospovirus species.

Abstract
Bivalve molluscs are key components of the estuarine environments as contributors to the trophic chain, and as filter -feeders, for maintaining ecosystem integrity. Further, clams, oysters, and scallops are commercially exploited around the world both as traditional local shellfisheries, and as intensive or semi-intensive farming systems. During the past decades, populations of those species deemed of environmental or commercial interest have been subject to close monitoring given the realization that these can suffer significant decline, sometimes irreversible, due to overharvesting, environmental pollution, or disease. Protozoans of the genera Perkinsus, Haplosporidium, Marteilia, and Bonamia are currently recognized as major threats for natural and farmed bivalve populations. Since their identification, however, the variable publication rates of research studies addressing these parasitic diseases do not always appear to reflect their highly significant environmental and economic impact. Here we analyzed the peer- reviewed literature since the initial description of these parasites with the goal of identifying potential milestone discoveries or achievements that may have driven the intensity of the research in subsequent years, and significantly increased publication rates. Our analysis revealed that after initial description of the parasite as the etiological agent of a given disease, there is a time lag before a maximal number of yearly publications are reached. This has already taken place for most of them and has been followed by a decrease in publication rates over the last decade (20- to 30- year lifetime in the literature). Autocorrelation analyses, however, suggested that advances in parasite purification and culture methodologies positively drive publication rates, most likely because they usually lead to novel molecular tools and resources, promoting mechanistic studies. Understanding these trends should help researchers in prioritizing research efforts for these and other protozoan parasites, together with their development as model systems for further basic and translational research in parasitic diseases.

Abstract
Perkinsus species are protistan parasites of molluscs. In Chesapeake Bay, Perkinsus marinus, Perkinsus chesapeaki, and Perkinsus andrewsi are sympatric, infecting oysters and clams. Although P. marinus is a pathogen for Crassostrea virginica, it remains unknown whether P. andrewsi and P. chesapeaki are equally pathogenic. Perkinsus species have been reported in C. virginica as far north as Maine, sometimes associated with high prevalence, but low mortality. Thus, we hypothesized that, in addition to P. marinus, Perkinsus species with little or no pathogenicity for C. virginica may be present. Accordingly, we investigated the distribution of Perkinsus species in C. virginica and Mercenaria mercenaria, collected from Maine to Virginia, by applying PCR-based assays specific for P. marinus, P. andrewsi, and a Perkinsus sp. isolated from M. mercenaria. DNA samples of M. mercenaria possessed potent PCR inhibitory activity, which was overcome by the addition of 1 mg/ml BSA and 5% (v/v) DMSO to the PCR reaction mixture. All 3 Perkinsus species were found in both host species throughout the study area. Interestingly, the prevalence of P. marinus in M. mercenaria was significantly lower than in C. virginica, suggesting that M. mercenaria is not an optimal host for P. marinus.

Abstract
Species of Perkinsus are responsible for high mortalities of bivalve molluscs world-wide. Techniques to accurately estimate parasites in tissues are required to improve understanding of perkinsosis. This study quantifies the number and tissue distribution of Perkinsus marinus in Crassostrea virginica by modern stereology and immunohistochemistry. Mean total number of trophozoites were (mean +/- SE) 11.80 +/- 3.91 million and 11.55 +/- 3.88 million for the optical disector and optical fractionator methods, respectively. The mean empirical error between both stereological approaches was 3.8 +/- 1.0%. Trophozoites were detected intracellularly in the following tissues: intestine (30.1%), Leydig tissue (21.3%), hemocytes (14.9%), digestive gland (11.4%), gills (6.1%), connective tissues (5.7%), gonads (4.1%), palps (2.2%), muscle (1.9%), mantle connective (0.8%), pericardium (0.7%), mantle epithelium (0.1%), and heart (0.1%). The remaining 0.6% were found extracellularly. Percentages of trophozoite stages were (mean +/- SE): large, log-phase trophonts, i.e., signet rings, 97.0 +/- 1.2%; meronts, 2.0 +/- 0.9%; clusters of small, log-phase trophonts, i.e., merozoites, 1.0 +/- 0.5%. Levels of infection in hemocytes and Leydig tissue were representative of total parasite intensity. These techniques are a powerful tool to follow parasite distribution and invasion, and to further explore mechanisms of Perkinsus spp. pathogenesis in bivalves.
