Abstract
In salt marsh ecosystems, daggerblade grass shrimp, Palaemon (Palaemonetes) pugio, play a crucial role in food webs and serve as the definitive host for the bopyrid isopod Probopyrus pandalicola. These ectoparasites infest the branchial chambers of grass shrimp, which can lead to decreased energy availability and sterilization of infected hosts. Although bopyrid isopod infestation of daggerblade grass shrimp has been frequently reported in literature from coastal marshes of the southeastern United States, the prevalence of this parasite has not been recently documented in daggerblade grass shrimp from marshes of the northeastern United States. The goal of this project was to quantify the prevalence of Pr. pandalicola infestations in Pa. pugio across Cape Cod, Massachusetts. We evaluated bopyrid isopod prevalence from shrimp collected from 5 different salt marsh habitats along Cape Cod in August 2021. Bopyrid isopod infestations were found in shrimp at 4 of 5 salt marshes, with prevalence ranging from 0.04 to 14.1%. Seasonal resampling of one of the salt marshes revealed the highest average infestation prevalence in spring (<17.1%) and an isolated high of 30.3% prevalence in a single salt panne. A series of linear and multivariate models showed that panne area, shrimp abundance, and distance to shoreline were related to Pr. pandalicola shrimp infestations in salt pannes in summer. This study describes the prevalence of the bopyrid isopod infesting daggerblade grass shrimp in salt marshes in New England, with implications for how parasitized shrimp influence salt marsh food webs in which they are found.

FISH & SHELLFISH IMMUNOLOGY 2022; 128:260-268. [PMID: 35934240 DOI: 10.1016/j.fsi.2022.07.074] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Revised: 07/19/2022] [Accepted: 07/25/2022] [Indexed: 06/15/2023]
Abstract
Diplothylacus sinensis is reported as an intriguing parasitic barnacle that can negatively affect the growth, molting, reproduction in several commercially important portunid crabs. To better understand the molecular mechanisms of host-parasite interactions, we characterized the gene expression profiles from the healthy and D. sinensis infected Portunus sanguinolentus by high-through sequence method. Totally, the transcriptomic analysis generated 52, 266, 600 and 51, 629, 604 high quality reads from the infected and control groups, respectively. The clean reads were assembled to 90,740 and 69,314 unigenes, with the average length of 760 bp and 709 bp, respectively. The expression analysis showed that 18,959 genes were significantly changed by the parasitism of D. sinensis, including 4769 activated genes and 14,190 suppressed genes. The differentially expressed genes were categorized into 258 KEGG pathways and 647 GO terms. The GO analysis mapped 13 DEGs related to immune system process and 32 DEGs related to immune response, respectively, suggesting a potential alteration of transcriptional expression patterns in complement cascades of P. sanguinolentus. Additionally, 4 representative molting-related genes were down-regulated in parasitized group, indicating D. sinensis infection appeared to suppress the producing of ecdysteroid hormones. In conclusion, the present study improves our understanding on parasite-host interaction mechanisms, which focuses the function of Ecdysone receptor, Toll-like receptor and cytokine receptor of crustacean crabs infestation with rhizocephalan parasites.

Abstract
The Palaemonetes sinensis aquaculture industry in Panjin City, Liaoning Province, China, experienced heavy losses in October 2018. Morbidity of cultured shrimp reached 50% and was characterized by cloudiness of muscle and the gradual spread of disease within the population. When the infection was mild, histopathological examinations revealed that the muscle cells contained a considerable number of microorganisms. In extreme cases, the structure of the hepatopancreatic glandular and muscle fiber was obscured or even vanished. Electron microscope observations revealed the presence of granular cytoplasmic inclusions in cells from hepatopancreas and muscle tissues. The 16S rDNA sequence of the intracytoplasmic organism was 94.7% identity to that of Coxiella burnetii. This is the first report of infection by C. burnetii in P. sinensis.

Abstract
The Chinese grass shrimp (Palaemonetes sinensis) was found with white turbidity appearance in the Panjin area. After dissection, typical symptoms of milky disease with hemolymph emulsification and noncoagulation were observed; however, the pathogen was unknown. In this study, we aimed to isolate the pathogen of the diseased P. sinensis. We found that the pathogen could grow on the fungal medium Bengal red, and microscopic examination showed that it reproduced by budding. Molecular identification of the isolated and purified yeast strain LNMB2021 based on 26S rDNA sequence showed that the pathogenic pathogen was Metschnikowia bicuspidata (GenBank OK094821), with 98.74% homology with M. bicuspidata strain LNES0119 (GenBank OK073903) and 98.56% with M. bicuspidata strain Liao (GenBank MT856369). The results of an artificial infection test showed that M. bicuspidata caused the same clinical symptoms in P. sinensis, and the isolated pathogen was still the same, which proved that P. sinensis was a new host of M. bicuspidata. Histopathological analysis showed that there were obvious pathological changes in the hepatopancreas and muscle tissue of the diseased P. sinensis. Identification of the pathogen is essential for the prevention and control of the disease and the healthy culture of P. sinensis. Furthermore, considering the transmissibility and cross-host transmission of M. bicuspidata, its risk of infecting other aquatic animals deserves high attention.

Abstract
Tachaea chinensis, a parasitic isopod, negatively affects the production of several commercially important shrimp species. To better understand the interaction between shrimp immunity and isopod infection, we performed a transcriptome analysis of the hepatopancreas of Palaemonetes sinensis challenged with T. chinensis. After assembly and annotation, 75,980 high-quality unigenes were obtained using RNA-seq data. Differential gene expression analysis revealed 896 significantly differently expressed genes (DEGs) after infection, with 452 and 444 upregulated and downregulated genes, respectively. Specifically, expression levels of genes involved in detoxification, such as the interferon regulatory factor, venom carboxylesterase-6, serine proteinase inhibitor, and cytochrome P450, were upregulated. Furthermore, expression levels of genes corresponding to retinol dehydrogenase, triosephosphate isomerase, variant ionotropic glutamate receptor, and phosphoenolpyruvate carboxykinase were significantly upregulated after isopod parasitization, indicating that the shrimp's visual system was influenced by isopod parasitization. Moreover, quantitative real-time PCR of 10 DEGs helped validate the RNA-seq findings. These results provide a valuable basis for future studies on the elucidation of immune responses of P. sinensis to T. chinensis infection.

[PMID: 34488635 PMCID: PMC8422745 DOI: 10.1186/s12862-021-01893-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Accepted: 08/20/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Chinese grass shrimp (Palaemonetes sinensis) is an important species widely distributed throughout China, which is ecologically relevant and possesses ornamental and economic value. These organisms have experienced a sharp decline in population due to overfishing. Therefore interest in P. sinensis aquaculture has risen in an effort to alleviate fishing pressure on wild populations. Therefore, we investigated the genetic diversity and variation of P. sinensis to verify the accuracy of previous research results, as well as to assess the risk of diversity decline in wild populations and provide data for artificial breeding. METHODS Palaemonetes sinensis specimens from seven locations were collected and their genetic variability was assessed based on mitochondrial COI gene segments. DNA sequence polymorphisms for each population were estimated using DNASP 6.12. The demographic history and genetic variation were evaluated using Arlequin 3.11. At last, the pairwise genetic distance (Ds) values and dendrograms were constructed with the MEGA 11 software package. RESULTS Our study obtained sequences from 325 individuals, and 41 haplotypes were identified among the populations. The haplotype diversity (Hd) and nucleotide diversity (π) indices ranged from 0.244 ± 0.083 to 0.790 ± 0.048 and from 0.0004 ± 0.0001 to 0.0028 ± 0.0006, respectively. Haplotype network analyses identified haplotype Hap_1 as a potential maternal ancestral haplotype for the studied populations. AMOVA results indicated that genetic variations mainly occurred within populations (73.07%). Moreover, according to the maximum variation among groups (FCT), analysis of molecular variance using the optimal two-group scheme indicated that the maximum variation occurred among groups (53.36%). Neutrality and mismatch distribution tests suggested that P. sinensis underwent a recent population expansion. Consistent with the SAMOVA analysis and haplotype network analyses, the Ds and FST between the population pairs indicated that the JN population was distinctive from the others. CONCLUSIONS Our study conducted a comprehensive characterization of seven wild P. sinensis populations, and our findings elucidated highly significant differences within populations. The JN population was differentiated from the other six populations, as a result of long-term geographical separation. Overall, the present study provided a valuable basis for the management of genetic resources and a better understanding of the ecology and evolution of this species.

Abstract
In this study, we describe in detail the life cycle of Tachaea chinensis (Isopoda: Corallanidae), a branchial ectoparasitic isopod that infests the freshwater shrimp Palaemonetes sinensis in China. We obtained 14 ovigerous T. chinensis females (8.22-11.92 mm in length) and observed the development of embryos through 5 sequential ontogenetic stages within the brood pouches (marsupium) of these females. The number of eggs or mancae (post-larval juveniles) held in the female marsupium ranged from 31 to 86, with a mean ± SD of 61.25 ± 16.16 eggs. Female T. chinensis were semelparous, i.e. individuals died following the release of mancae from the marsupium. Released mancae were non-planktonic and immediately infective to host shrimps. However, only a few mancae successfully established contact with a host, and it is thus assumed that the remainder were predated by shrimp. Attached T. chinensis fed on the host hemolymph, and subsequent to host death, these isopods typically searched for a new host. We also found that T. chinensis exhibits a host preference: most mancae attached to P. sinensis rather than to Neocaridina sp. or Macrobrachium nipponense. This study provides valuable empirical data that will support future research on the prevention and control of parasitic isopod infections.

MicroRNA transcriptome analysis of oriental river prawn Macrobrachium nipponense in responding to starvation stress. COMPARATIVE BIOCHEMISTRY AND PHYSIOLOGY D-GENOMICS & PROTEOMICS 2021; 38:100820.

Abstract
Food deprivation or fasting is an important environmental factor, and a regular occurrence in both natural aquatic habitats and artificial ponds. However, the potential immunoregulatory mechanisms underlying starvation stress in crustaceans remain unclear. MicroRNAs (miRNAs) are a new class of non-coding RNAs that can regulate various biological processes, such as stress and immune responses. In the present work, miRNAs related to starvation stress responses and immune properties were identified and characterised in oriental river prawn Macrobrachium nipponense using high-throughput sequencing and bioinformatics analyses. Twelve small RNA libraries from hepatopancreas tissue were sequenced across four fasting stages lasting 0, 7, 14 or 21 days. In total, 550 miRNAs were identified including 198 putative novel miRNAs and 352 conserved miRNAs belonging to 57 families. Moreover, compared with expression levels at 0 days, 27, 27 and 43 miRNAs were differentially expressed (DE-miRNAs) at 7, 14 and 21 days, respectively. Among these, four DE-miRNAs (ame-miR-190-5p, dme-miR-307a-3p, hme-miR-2788-3p and novel_68) were co-expressed at all three timepoints. Furthermore, 661 target genes regulated by these DE-miRNAs were identified, and associated functional annotations were derived by GO enrichment and KEGG pathway analyses, which showed that most DE-miRNAs were mainly participated in metabolic processes and immune responses. Furthermore, 26 host DE-miRNAs potentially participated in interactions with white spot syndrome virus (WSSV) were identified by predicting and analysing target genes from WSSV. The further WSSV challenge under starvation stress showed that dme-miR-307a-3p played a part in the antiviral responses against WSSV. Our results demonstrate that dme-miR-307a-3p may play vital regulatory roles in responding to starvation stress and WSSV infection. The findings contribute new insight into the molecular mechanisms associated with immune responses to environmental stress in crustaceans.

Abstract
Gyrodactylid monogeneans are widespread parasites of teleost fishes, and infection with these parasites results in high host morbidity and mortality in aquaculture. To comprehensively elucidate the immune mechanisms against Gyrodactylus kobayashii, the transcriptome profiles of goldfish (Carassius auratus) skin after challenge with G. kobayashii were first investigated using next-generation sequencing. Approximately 21 million clean reads per library were obtained, and the average percentage of these clean reads mapped to the reference genome was 82.25%. A total of 556 differentially expressed genes (DEGs), including 344 upregulated and 212 downregulated genes, were identified, and 380 DEGs were successfully annotated and assigned to 95 signaling pathways in Kyoto Encyclopedia of Genes and Genomes (KEGG). In addition, 14 pathways associated with immune response were identified mainly including mTOR signaling pathway, cytokine-cytokine receptor interaction, intestinal immune network for IgA production, toll-like receptor signaling pathway, and phagosome. Twelve genes were selected and validated using qRT-PCR. A similar trend of these genes between RNA-Seq and qRT-PCR was observed, indicating that RNA-Seq data was reliable. Besides, the ALP activity and NO content in serum were significantly higher in the infected goldfish compared with the non-infected goldfish. In summary, this study provides better understandings of immune defense mechanisms of goldfish against G. kobayashii, which will support future molecular research on gyrodactylids and facilitate the prevention and treatment of gyrodactylosis in aquaculture.

Abstract
Tachaea chinensis is a parasitic isopod that negatively affects the production of several commercially important shrimp species in China. To date, there have been no reports on the antioxidant and immune responses of host shrimps to isopod parasite infection or their underlying molecular mechanisms. In this study, we examined the specific activities of the immune and antioxidant enzymes of the shrimp Macrobrachium nipponense during the course of a 15-day isopod infection and evaluated expression of related genes. Acid phosphatase (ACP) and alkaline phosphatase (AKP) activities and malondialdehyde (MDA) levels showed significant peaks over 15 days of exposure in both the hepatopancreas and muscle (P < 0.05), whereas catalase (CAT) activity increased continuously during infection (P < 0.05), and lysozyme (LZM) activity increased only in the hepatopancreas (P < 0.05). After 6 days of exposure, expressions of glutathione S-transferase (GST), ACP, and AKP were significantly higher than at 12 days. Compared with the control group, at 12 days, S-(hydroxymethyl) glutathione dehydrogenase activity and glutathione metabolism pathways were significantly inhibited (P < 0.05). Furthermore, the NOD-like receptor signaling pathway and antigen processing and presentation pathways were also significantly inhibited at 12 days compared with that at 6 days (P < 0.05), indicating that T. chinensis parasitism could perturb the antioxidant and immune systems of shrimp hosts during the latter stages of infection. Additionally, the molting and mortality rates of M. nipponense increased the duration of parasitism. These findings indicate that M. nipponense can activate antioxidant and immune defense systems during the early period during isopod parasitism, whereas the parasite can negatively affect these host defense systems during the latter period. Our findings accordingly provide valuable insights into the antioxidant defense systems and immune function characterizing parasite-host interactions.

Abstract
Tachaea chinensis, a parasitic isopod, negatively affects the production of several commercially important shrimp species in China. The mechanism of parasite-host interaction cannot be accurately described by transcriptomic and proteomic approaches individually. Here, comparative metabolite profiling was used to achieve a broad coverage of primary metabolite changes in Chinese grass shrimp Palaemonetes sinensis following T. chinensis parasitization. In total, 66 metabolites were significantly differentially accumulated between the control and infected groups; of these, 19 were upregulated and 47 were downregulated after T. chinensis infection. Moreover, the Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis revealed that 10 pathways were significantly enriched. The protein digestion and absorption pathways were highly enriched, followed by the mineral absorption, aminoacyl-tRNA biosynthesis, biosynthesis of amino acids, and metabolic metabolism pathways. Parasitization by T. chinensis enhanced the glycolytic pathway and tricarboxylic acid (TCA) cycle in P. sinensis, thereby releasing more energy for swimming, foraging, and evading predation. Glucogenic amino acids such as alanine, histidine, glutamine, and proline were consumed to generate glutamate and enhance the TCA cycle. Nucleotide-related metabolic pathways were downregulated, possibly because T. chinensis can secrete molecules to degrade nucleotides and inhibit hemostasis and inflammatory responses. These results suggest that the isopod parasite can increase the host's metabolic burden by enhancing the host's TCA cycle and secreting molecules to degrade host proteins, thereby enabling the parasite to feed on the host and inhibit an inflammatory response. The results will be a valuable contribution to understanding the metabolic responses of crustaceans to isopod parasitism.

Abstract
Tachaea chinensis Thielemann, 1910 (Isopoda: Corallanidae) is a branchial ectoparasite that attaches onto shrimps and prawns. However, the distribution of T. chinensis in China, especially its epidemiology, remains unclear. We determined the prevalence of T. chinensis on the ridgetail white prawn (Exopalaemon carinicauda Holthuis, 1950) in Jiangsu Province. Fifty ponds in 10 shrimp farms were assessed. Isopod species were identified by morphological features and mitochondrial 16S rRNA gene analysis. A literature review was performed to determine the geographical distribution of T. chinensis in China. Published data revealed that T. chinensis was geographically distributed throughout five provinces in China, including Liaoning, Tianjin, Henan, Hubei, and Guangxi. A total of 998 T. chinensis were collected from 50 ridgetail white prawn ponds in Yancheng City and Rudong County. Tachaea chinensis prevalence ranged from 0.98% to 4.42% in Yancheng City and 0.62% to 0.92% in Rudong County. This is the first study to investigate the geographical distribution of T. chinensis in China and determine the prevalence of T. chinensis on the ridgetail white prawn in Jiangsu Province. Overall, we provide available data that fill gaps in the epidemiology of T. chinensis.

Abstract
The aim of this study was to determine the complete mitochondrial genome (mitogenome) and the phylogenetic location of the Palaemonetes sinensis. The mitogenome was 15,736 bp in length, containing 22 transfer RNA genes (tRNAs), 13 protein-coding genes (PCGs), 2 ribosome RNA genes (rRNAs), and a control region (CR). The overall nucleotide composition is as follows: A, 35.69%; C, 21.66%; G, 12.39%; T, 30.26%. Nine and four PCGs were encoded on the heavy and light strands, respectively. Phylogenetic analysis suggested that P. sinensis shares a close relationship with Palaemon serenus and Palaemon capensis. These findings are helpful for better understanding the phylogenetic relationship among Caridea, as well as investigating the population genetics of P. sinensis in the future.

Abstract
As a crucial neuroendocrine-immune factor, dopamine (DA) could regulate the immune system of Litopenaeus vannamei. To understand the immune mechanisms and regulatory pathways of DA in L. vannamei, the transcriptome analysis of hemocytes of L. vannamei with injection of DA (10-6 mol/shrimp) at 3 and 12 h were performed in this study. Moreover, quantitative real-time PCR (qPCR) method was applied to validate the accuracy of transcriptome sequencing and analyze the expression pattern of candidate differentially expressed genes (DEGs) at different time points (0, 3, 6, 12, and 24 h) after DA injection. The results showed that a total of 51382 unigenes with a N50 length of 2341 bp were generated. And 1397 and 457 DEGs were obtained by comparative transcriptome at 3 and 12h respectively. Moreover, the results of functional annotation and enriched pathway showed that the DEGs were involved in phagosome (ko04145), lysosome (ko04142), Endocytosis (ko04144), and NOD-like receptor signaling pathway (ko04621). Besides, the Pearson's correlation coefficient (R) between transcriptome sequencing and qPCR was 0.845, which confirmed the reliability of the transcriptome sequencing results and the accuracy of assembly. Furthermore, the expression pattern of 15 candidate DEGs, containing 9 up-regulated and 6 down-regulated DEGs at 3 h, indicated the regulation of DA in physiological functions especially in the immune system. Therefore, these results revealed that DA induced the expressions of membrane receptors or proteins, activated intracellular signaling pathways, regulated cellular and humoral immune systems, controlled antioxidation and apoptosis, and was involved in the regulation of neuroendocrine system. These findings are helpful to promote the understanding on the effects of biogenic amines on physiological functions and regulatory networks of crustacean, and offer a substantial material and foundation for researching the immune response of crustacean.

Abstract
Parasitic isopods perforate and attach to the host integument via the mandibles and then feed on hemolymph and exudate from the wounds. Such isopods attack a variety of commercially important fish and crustacean hosts. Similar to other hematophagous parasites, isopods may also employ biomolecules that affect host blood conglutination and defense systems. In the present study, a tandem mass tag-based quantitative proteomic approach was used to identify differentially expressed proteins in Tachaea chinensis parasites of shrimp, by comparing parasitic (fed) and pre-parasitic (unfed) individuals. We identified 888 proteins from a total of 1,510 peptides, with a significant difference in 129 between the fed and unfed groups. Among these, 37 were upregulated and 92 were downregulated in unfed T. chinensis. This indicates that T. chinensis may require more energy before parasitism during its search for a host. In addition, as is the case for other blood-sucking parasites, it might secrete antihemostatic, anti-inflammatory, and immunomodulatory molecules to facilitate blood meal acquisition. To our knowledge, this study is the first to use a TMT-based proteomic approach to analyze the proteome of isopod parasites, and the results will facilitate our understanding of the molecular mechanisms of isopod parasitism on crustaceans.

Abstract
BACKGROUND Although parasitic isopods can negatively affect the reproduction and ingestion of several commercially important crustaceans, little is known regarding the mechanisms that underlie these effects. METHODS In the present study, the iTRAQ (isobaric tags for relative and absolute quantification) approach was applied to identify differentially expressed proteins in the Chinese grass shrimp Palaemonetes sinensis infected with the parasitic isopod Tachaea chinensis. RESULTS On the basis of our analysis, we identified 1262 proteins from a total of 4292 peptides. There was a significant difference in the expression of 182 proteins between the control and infected groups, among which 69 were upregulated and 113 were downregulated after T. chinensis infection. The differentially expressed proteins revealed that parasitism may inhibit the immune response, thereby increasing host vulnerability to additional lethal infection. Furthermore, T. chinensis may secrete anticoagulants to inhibit hemolymph clotting. Moreover, the isopod parasite placed a heavy metabolic burden on the host, particularly with respect to glucose metabolism. CONCLUSIONS Our study is the first to use the iTRAQ-based proteomic approach to analyze the effects of an isopod parasite on its host. The results we obtained using this approach will make a valuable contribution to understanding the molecular mechanisms underlying isopod parasitism on crustaceans.
