Distinguishing the molecular diversity, nutrient content, and energetic potential of exometabolomes produced by macroalgae and reef-building corals.

Metabolites exuded by primary producers comprise a significant fraction of marine dissolved organic matter, a poorly characterized, heterogenous mixture that dictates microbial metabolism and biogeochemical cycling. We present a foundational untargeted molecular analysis of exudates released by coral reef primary producers using liquid chromatography-tandem mass spectrometry to examine compounds produced by two coral species and three types of algae (macroalgae, turfing microalgae, and crustose coralline algae [CCA]) from Mo'orea, French Polynesia. Of 10,568 distinct ion features recovered from reef and mesocosm waters, 1,667 were exuded by producers; the majority (86%) were organism specific, reflecting a clear divide between coral and algal exometabolomes. These data allowed us to examine two tenets of coral reef ecology at the molecular level. First, stoichiometric analyses show a significantly reduced nominal carbon oxidation state of algal exometabolites than coral exometabolites, illustrating one ecological mechanism by which algal phase shifts engender fundamental changes in the biogeochemistry of reef biomes. Second, coral and algal exometabolomes were differentially enriched in organic macronutrients, revealing a mechanism for reef nutrient-recycling. Coral exometabolomes were enriched in diverse sources of nitrogen and phosphorus, including tyrosine derivatives, oleoyl-taurines, and acyl carnitines. Exometabolites of CCA and turf algae were significantly enriched in nitrogen with distinct signals from polyketide macrolactams and alkaloids, respectively. Macroalgal exometabolomes were dominated by nonnitrogenous compounds, including diverse prenol lipids and steroids. This study provides molecular-level insights into biogeochemical cycling on coral reefs and illustrates how changing benthic cover on reefs influences reef water chemistry with implications for microbial metabolism.

Viral predation pressure on coral reefs.

BACKGROUND: Predation pressure and herbivory exert cascading effects on coral reef health and stability. However, the extent of these cascading effects can vary considerably across space and time. This variability is likely a result of the complex interactions between coral reefs' biotic and abiotic dimensions. A major biological component that has been poorly integrated into the reefs' trophic studies is the microbial community, despite its role in coral death and bleaching susceptibility. Viruses that infect bacteria can control microbial densities and may positively affect coral health by controlling microbialization. We hypothesize that viral predation of bacteria has analogous effects to the top-down pressure of macroorganisms on the trophic structure and reef health. RESULTS: Here, we investigated the relationships between live coral cover and viruses, bacteria, benthic algae, fish biomass, and water chemistry in 110 reefs spanning inhabited and uninhabited islands and atolls across the Pacific Ocean. Statistical learning showed that the abundance of turf algae, viruses, and bacteria, in that order, were the variables best predicting the variance in coral cover. While fish biomass was not a strong predictor of coral cover, the relationship between fish and corals became apparent when analyzed in the context of viral predation: high coral cover (> 50%) occurred on reefs with a combination of high predator fish biomass (sum of sharks and piscivores > 200 g m-2) and high virus-to-bacteria ratios (> 10), an indicator of viral predation pressure. However, these relationships were non-linear, with reefs at the higher and lower ends of the coral cover continuum displaying a narrow combination of abiotic and biotic variables, while reefs at intermediate coral cover showed a wider range of parameter combinations. CONCLUSIONS: The results presented here support the hypothesis that viral predation of bacteria is associated with high coral cover and, thus, coral health and stability. We propose that combined predation pressures from fishes and viruses control energy fluxes, inhibiting the detrimental accumulation of ecosystem energy in the microbial food web.

Coral larval settlement induction using tissue-associated and exuded coralline algae metabolites and the identification of putative chemical cues.

Reef-building crustose coralline algae (CCA) are known to facilitate the settlement and metamorphosis of scleractinian coral larvae. In recent decades, CCA coverage has fallen globally and degrading environmental conditions continue to reduce coral survivorship, spurring new restoration interventions to rebuild coral reef health. In this study, naturally produced chemical compounds (metabolites) were collected from two pantropical CCA genera to isolate and classify those that induce coral settlement. In experiments using four ecologically important Caribbean coral species, we demonstrate the applicability of extracted, CCA-derived metabolites to improve larval settlement success in coral breeding and restoration efforts. Tissue-associated CCA metabolites induced settlement of one coral species, Orbicella faveolata, while metabolites exuded by CCA (exometabolites) induced settlement of three species: Acropora palmata, Colpophyllia natans and Orbicella faveolata. In a follow-up experiment, CCA exometabolites fractionated and preserved using two different extraction resins induced the same level of larval settlement as the unfractionated positive control exometabolites. The fractionated CCA exometabolite pools were characterized using liquid chromatography tandem mass spectrometry, yielding 145 distinct molecular subnetworks that were statistically defined as CCA-derived and could be classified into 10 broad chemical classes. Identifying these compounds can reveal their natural prevalence in coral reef habitats and facilitate the development of new applications to enhance larval settlement and the survival of coral juveniles.

Herbivorous Fish Microbiome Adaptations to Sulfated Dietary Polysaccharides.

Marine herbivorous fish that feed primarily on macroalgae, such as those from the genus Kyphosus, are essential for maintaining coral health and abundance on tropical reefs. Here, deep metagenomic sequencing and assembly of gut compartment-specific samples from three sympatric, macroalgivorous Hawaiian kyphosid species have been used to connect host gut microbial taxa with predicted protein functional capacities likely to contribute to efficient macroalgal digestion. Bacterial community compositions, algal dietary sources, and predicted enzyme functionalities were analyzed in parallel for 16 metagenomes spanning the mid- and hindgut digestive regions of wild-caught fishes. Gene colocalization patterns of expanded carbohydrate (CAZy) and sulfatase (SulfAtlas) digestive enzyme families on assembled contigs were used to identify likely polysaccharide utilization locus associations and to visualize potential cooperative networks of extracellularly exported proteins targeting complex sulfated polysaccharides. These insights into the gut microbiota of herbivorous marine fish and their functional capabilities improve our understanding of the enzymes and microorganisms involved in digesting complex macroalgal sulfated polysaccharides. IMPORTANCE This work connects specific uncultured bacterial taxa with distinct polysaccharide digestion capabilities lacking in their marine vertebrate hosts, providing fresh insights into poorly understood processes for deconstructing complex sulfated polysaccharides and potential evolutionary mechanisms for microbial acquisition of expanded macroalgal utilization gene functions. Several thousand new marine-specific candidate enzyme sequences for polysaccharide utilization have been identified. These data provide foundational resources for future investigations into suppression of coral reef macroalgal overgrowth, fish host physiology, the use of macroalgal feedstocks in terrestrial and aquaculture animal feeds, and the bioconversion of macroalgae biomass into value-added commercial fuel and chemical products.

A Pilot Study of Adolescents with Psychotic Experiences: Potential Cerebellar Circuitry Disruption Early Along the Psychosis Spectrum.

A berrant connectivity in the cerebellum has been found in psychotic conditions such as schizophrenia corresponding with cognitive and motor deficits found in these conditions. Diffusion differences in the superior cerebellar peduncles, the white matter connecting the cerebellar circuitry to the rest of the brain, have also been found in schizophrenia and high-risk states. However, white matter diffusivity in the peduncles in individuals with sub-threshold psychotic experiences (PEs) but not reaching the threshold for a definitive diagnosis remains unstudied. This study investigates the cerebellar peduncles in adolescents with PEs but no formal psychiatric diagnosis.Sixteen adolescents with PEs and 17 age-matched controls recruited from schools underwent High-Angular-Resolution-Diffusion neuroimaging. Following constrained spherical deconvolution whole-brain tractography, the superior, inferior and middle peduncles were isolated and virtually dissected out using ExploreDTI. Differences for macroscopic and microscopic tract metrics were calculated using one-way between-group analyses of covariance controlling for age, sex and estimated Total Intracranial Volume (eTIV). Multiple comparisons were corrected using Bonferroni correction.A decrease in fractional anisotropy was identified in the right (p = 0.045) and left (p = 0.058) superior cerebellar peduncle; however, this did not survive strict Bonferroni multiple comparison correction. There were no differences in volumes or other diffusion metrics in either the middle or inferior peduncles.Our trend level changes in the superior cerebellar peduncle in a non-clinical sample exhibiting psychotic experiences complement similar but more profound changes previously found in ultra-high-risk individuals and those with psychotic disorders. This suggests that superior cerebellar peduncle circuitry perturbations may occur early along in the psychosis spectrum.

Guidelines for Qualifications of Neurodiagnostic Personnel: A Joint Position Statement of the American Clinical Neurophysiology Society, the American Association of Neuromuscular & Electrodiagnostic Medicine, the American Society of Neurophysiological Monitoring, and ASET The Neurodiagnostic Society.

The Guidelines for Qualifications of Neurodiagnostic Personnel (QNP) document has been created through the collaboration of the American Clinical Neurophysiology Society (ACNS), the American Society of Neurophysiological Monitoring (ASNM), the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM), and ASET The Neurodiagnostic Society (ASET). The quality of patient care is optimized when neurophysiological procedures are performed and interpreted by appropriately trained and qualified practitioners at every level. These societies recognize that neurodiagnostics is a large field with practitioners who have entered the field through a variety of training paths. This document suggests job titles, associated job responsibilities, and the recommended levels of education, certification, experience, and ongoing education appropriate for each job. This is important because of the growth and development of standardized training programs, board certifications, and continuing education in recent years. This document matches training, education, and credentials to the various tasks required for performing and interpreting neurodiagnostic procedures. This document does not intend to restrict the practice of those already working in neurodiagnostics. It represents recommendations of these societies with the understanding that federal, state, and local regulations, as well as individual hospital bylaws, supersede these recommendations. Because neurodiagnostics is a growing and dynamic field, the authors fully intend this document to change over time.

A multiomic analysis of in situ coral-turf algal interactions.

Viruses, microbes, and host macroorganisms form ecological units called holobionts. Here, a combination of metagenomic sequencing, metabolomic profiling, and epifluorescence microscopy was used to investigate how the different components of the holobiont including bacteria, viruses, and their associated metabolites mediate ecological interactions between corals and turf algae. The data demonstrate that there was a microbial assemblage unique to the coral-turf algae interface displaying higher microbial abundances and larger microbial cells. This was consistent with previous studies showing that turf algae exudates feed interface and coral-associated microbial communities, often at the detriment of the coral. Further supporting this hypothesis, when the metabolites were assigned a nominal oxidation state of carbon (NOSC), we found that the turf algal metabolites were significantly more reduced (i.e., have higher potential energy) compared to the corals and interfaces. The algae feeding hypothesis was further supported when the ecological outcomes of interactions (e.g., whether coral was winning or losing) were considered. For example, coral holobionts losing the competition with turf algae had higher Bacteroidetes-to-Firmicutes ratios and an elevated abundance of genes involved in bacterial growth and division. These changes were similar to trends observed in the obese human gut microbiome, where overfeeding of the microbiome creates a dysbiosis detrimental to the long-term health of the metazoan host. Together these results show that there are specific biogeochemical changes at coral-turf algal interfaces that predict the competitive outcomes between holobionts and are consistent with algal exudates feeding coral-associated microbes.

'Pinholes in my arms': the vicious cycle of vascular access.

BACKGROUND: Vascular access devices (VADs) are essential for delivery of intravenous therapies. There are notable gaps in the literature regarding a focus on patient experience and meaning-making related to living with a VAD, specifically a central venous access device (CVAD). AIMS: To explore how patients make sense of living with a CVAD. METHODS: This study followed an interpretive phenomenological analysis (IPA) approach. Purposive sampling was used to identify 11 cancer patients who had a CVAD in situ. One-to-one semi-structured interviews were performed. Interviews were digitally recorded, transcribed and analysed by the lead author. FINDINGS: Four superordinate themes were identified: the self under attack; being rescued/being robbed; protection of others/protection of self; bewilderment and dismay at lack of staff competence. CONCLUSION: Having a CVAD affects the psychological, social, and personal self and impacts on self-esteem and self-image. Despite this, CVADs are accepted by patients and are eventually 'embodied' by them.

Elevated pCO2 alters marine heterotrophic bacterial community composition and metabolic potential in response to a pulse of phytoplankton organic matter.

Factors that affect the respiration of organic carbon by marine bacteria can alter the extent to which the oceans act as a sink of atmospheric carbon dioxide. We designed seawater dilution experiments to assess the effect of pCO2 enrichment on heterotrophic bacterial community composition and metabolic potential in response to a pulse of phytoplankton-derived organic carbon. Experiments included treatments of elevated (1000 p.p.m.) and low (250 p.p.m.) pCO2 amended with 10 µmol L-1 dissolved organic carbon from Emiliana huxleyi lysates, and were conducted using surface-seawater collected from the South Pacific Subtropical Gyre. To assess differences in community composition and metabolic potential, shotgun metagenomic libraries were sequenced from low and elevated pCO2 treatments collected at the start of the experiment and following exponential growth. Our results indicate bacterial communities changed markedly in response to the organic matter pulse over time and were significantly affected by pCO2 enrichment. Elevated pCO2 also had disproportionate effects on the abundance of sequences related to proton pumps, carbohydrate metabolism, modifications of the phospholipid bilayer, resistance to toxic compounds and conjugative transfer. These results contribute to a growing understanding of the effects of elevated pCO2 on bacteria-mediated carbon cycling during phytoplankton bloom conditions in the marine environment.

Risk factors and outcome of repair of obstetric anal sphincter injuries as followed up in a dedicated perineal clinic.

INTRODUCTION AND HYPOTHESIS: Faecal incontinence can be a devastating outcome with social, psychological and physical repercussions, and it occurs in 10-61% following obstetric anal sphincter injury (OASIS). The aim of our study was to determine the contributing factors in the development of severity of OASIS and to correlate anal sphincter tone with the extent of anal sphincter injury. METHODS: A prospective cohort study was performed of all patients attending the postnatal perineal clinic at 4-12 months postpartum, from January 2016 until October 2017. Women were categorised into minor tears (3a and 3b) and major tears (3c and 4th degree). RESULTS: The mean age was 33.9 years (4.2); the mean parity was 1.6 (range 1-5). A total of 75 women (17%) were reviewed following a major tear (4th degree, n = 28, 3c, n = 47) and 362 (83%) were reviewed following a minor tear (3a n = 188, 3b, n = 174). Following analysis of numerous obstetric variables, it was shown that women who had an instrumental delivery were more likely to have a major tear compared with those who had a spontaneous vaginal delivery (p = 0.05). A significant difference was found in the distributions of symptom score between groups (p < 0.001). Women with combined defects were most likely to have reduced anal tone (p < 0.001) compared with any other group. CONCLUSIONS: The perineal clinic provides a valuable resource for investigation and treatment of OASIS, providing a targeted pathway for management. We suggest that endoanal ultrasound and digital rectal examination are complimentary investigations which correlate well with each other.

Health professionals' lack of knowledge of central venous access devices: the impact on patients.

BACKGROUND: the literature on the patient experience of living with a central venous access device (CVAD) is growing, but remains sparse. It suggests that patients accept having a CVAD as it should reduce episodes of repeated cannulations. However, a recent doctoral study found the reality did not live up to this hope. AIM: the study objective was to uncover the global, cross-disease experience of patients with CVADs. METHOD: an online survey was sent to an international sample of people living with CVADs. FINDINGS: 74 people from eight countries responded. Respondents corroborated the PhD findings: painful cannulation attempts continued after CVAD insertion because of a lack of clinical knowledge. Participants lost trust in clinicians and feared complications due to poor practice. CONCLUSION: clinicians often lack the necessary skills to care and maintain CVADs. This leads to a negative patient experience.

Plugging the patient evidence gap: what patients with swallowing disorders post-stroke say about thickened liquids.

BACKGROUND: Oropharyngeal dysphagia post-stroke is well known, with its presence increasing the risk of poor outcomes in particular aspiration and aspiration pneumonia. Management to minimize the risk of aspiration and improve swallow safety post-stroke includes the treatment of thickened liquids (TL), an established bolus modification intervention. Despite widespread use, there is a lack of robust empirical evidence and minimal patient evidence as to the experience and acceptability of using thickeners by people who experience dysphagia after a stroke. AIMS: To explore people with swallowing disorders post-stroke experiences of and acceptability regarding the bolus modification treatment of thickened liquids. METHODS & PROCEDURES: A qualitative, descriptive study exploring the experiences of individuals given TL after their stroke. A purposive sample of 14 adults was obtained with data collection and generation through the medium of individual semi-structured interviews. Inductive thematic analysis was used to analyse the data. OUTCOMES & RESULTS: Three overarching themes of 'uncertainty', 'an unpleasant experience' and 'a trade-off' were identified. These themes highlight that participants disliked TL and this dislike may have impacted clinically in terms of adherence, hydration and quality of life. Lack of sensory appeal was important in framing patient dislike. Participants' involvement in and understanding of reasons for prescription of TL was poor leading to uncertainty regarding the treatment. Notwithstanding, some participants felt it was necessary for their stroke recovery. CONCLUSIONS & IMPLICATIONS: TL can be considered a burdensome treatment from multiple perspectives including product palatability, treatment uncertainty and treatment adherence issues. Despite intensely disliking this treatment, some patients ultimately understand why the treatment is prescribed. Improvements in product palatability are required in order to improve adherence and patient quality of life. Consideration of other treatment options and newer products to manage aspiration post-stroke is also warranted.

Medical device classification: focus on vascular access.

Developments in the medical device industry are driven by a rapidly changing healthcare arena in combination with advances in technological fields such as materials science, bio-engineering and electronics. Subsequently, it is now estimated that over 500 000 different types of medical devices are produced globally. This article aims to give a simple explanation of device classification as it relates to vascular access devices. It aims to provide the reader with information to increase their knowledge and understanding of this topic.

Asenapine for the treatment of adults with an acute exacerbation of schizophrenia: results from a randomized, double-blind, fixed-dose, placebo-controlled trial with olanzapine as an active control.

OBJECTIVE: Evaluate the efficacy and safety of asenapine 2.5 mg twice daily (bid; n=97) or 5 mg bid (n=113) versus placebo (n=101) in adults with acute exacerbation of schizophrenia. METHODS: Adults with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) schizophrenia diagnosis were randomized to asenapine 2.5 mg bid, 5 mg bid, placebo, or olanzapine 15 mg once daily. The primary objective was to test superiority of asenapine versus placebo as measured by the change from baseline to day 42 in the Positive and Negative Syndrome Scale (PANSS) total score. The key safety objective was to evaluate weight change in asenapine versus olanzapine at day 42. RESULTS: The primary efficacy endpoint was met; the difference in least squares mean change from baseline to day 42 in PANSS total score between asenapine 5 mg bid and placebo was -5.5 points (unadjusted 95% CI: -10.1, -1.0; multiplicity adjusted P=0.0356). Neither asenapine 2.5 mg bid nor olanzapine 15mg were superior to placebo. Both asenapine groups demonstrated significantly less weight gain than olanzapine at day 42. Significantly higher incidences of oral hypoesthesia and dysgeusia (combined) for asenapine 2.5 mg bid (5.2% vs 0.0%; P=0.0217) and 5 mg bid (7.1% vs 0.0%; P=0.0033) were observed versus placebo. There were no significant differences between asenapine and placebo for insomnia, extrapyramidal symptoms, akathisia, dizziness, or combination of somnolence/sedation/hypersomnia. CONCLUSION: This study supports previous efficacy and safety findings of asenapine; asenapine 5 mg bid is the lowest effective dose in adults with schizophrenia. Asenapine was associated with significantly less weight gain than olanzapine at day 42.

Local genomic adaptation of coral reef-associated microbiomes to gradients of natural variability and anthropogenic stressors.

Holobionts are species-specific associations between macro- and microorganisms. On coral reefs, the benthic coverage of coral and algal holobionts varies due to natural and anthropogenic forcings. Different benthic macroorganisms are predicted to have specific microbiomes. In contrast, local environmental factors are predicted to select for specific metabolic pathways in microbes. To reconcile these two predictions, we hypothesized that adaptation of microbiomes to local conditions is facilitated by the horizontal transfer of genes responsible for specific metabolic capabilities. To test this hypothesis, microbial metagenomes were sequenced from 22 coral reefs at 11 Line Islands in the central Pacific that together span a wide range of biogeochemical and anthropogenic influences. Consistent with our hypothesis, the percent cover of major benthic functional groups significantly correlated with particular microbial taxa. Reefs with higher coral cover had a coral microbiome with higher abundances of Alphaproteobacteria (such as Rhodobacterales and Sphingomonadales), whereas microbiomes of algae-dominated reefs had higher abundances of Gammaproteobacteria (such as Alteromonadales, Pseudomonadales, and Vibrionales), Betaproteobacteria, and Bacteriodetes. In contrast to taxa, geography was the strongest predictor of microbial community metabolism. Microbial communities on reefs with higher nutrient availability (e.g., equatorial upwelling zones) were enriched in genes involved in nutrient-related metabolisms (e.g., nitrate and nitrite ammonification, Ton/Tol transport, etc.). On reefs further from the equator, microbes had more genes encoding chlorophyll biosynthesis and photosystems I/II. These results support the hypothesis that core microbiomes are determined by holobiont macroorganisms, and that those core taxa adapt to local conditions by selecting for advantageous metabolic genes.

Needle-free devices: keeping the system closed.

Health professionals are under increasing pressure to reduce costs while ensuring patient safety. As the number of vascular access devices (VADs) used in health care continues to increase, there is a need to reduce the complications of infection and occlusion associated with them. Needle-free devices (NFDs), also known as needleless connectors, have been available since the early 1990s and the type and variety of these devices has continued to develop. As well as the original aim of NFDs to maintain a closed system and to reduce the risk of needlestick injuries and blood spillage, NFDs are now designed with the aim of improving clinical outcomes by reducing the common complications of infection and catheter occlusion. As there are a number of NFDs available with specific designs, it is imperative that health professionals have an understanding of the different types and functions. This article provides an explanation of NFD design and functions and guidance and information about their benefits, as well as advice on preventing complications associated with their use.

A blended learning approach to teaching CVAD care and maintenance.

Nurses working within both acute and primary care settings are required to care for and maintain central venous access devices (CVADs). To support these nurses in practice, a higher education institution and local health board developed and delivered CVAD workshops, which were supported by a workbook and competency portfolio. Following positive evaluation of the workshops, an electronic learning (e-learning) package was also introduced to further support this clinical skill in practice. To ascertain whether this blended learning approach to teaching CVAD care and maintenance prepared nurses for practice, the learning package was evaluated through the use of electronic questionnaires. Results highlighted that the introduction of the e-learning package supported nurses' practice, and increased their confidence around correct clinical procedures.

Hickman catheter and implantable port devices for the delivery of chemotherapy: a phase II randomised controlled trial and economic evaluation.

BACKGROUND: In the United Kingdom, totally implantable venous access systems (TIVAS) are not routinely used. Compared with Hickman catheters, these devices are more expensive and complex to insert. However, it is unclear whether the higher costs may be offset by perceived greater health benefits. This pilot trial aimed to generate relevant data to inform the design of a larger definitive randomised controlled trial. METHODS: This was a phase II prospective, randomised, open trial from two UK oncology centres. The primary end point was overall complication rate. Secondary end points included individual complication rates, time to first complication and quality of life. Analysis was by intention to treat. An economic evaluation was also carried out. RESULTS: A total of 100 patients were randomised in a 3 : 1 ratio to receive a Hickman or a TIVAS. Overall, 54% of patients in the Hickman arm suffered one or more complications compared with 38% in the TIVAS arm (one-sided P=0.068). In the Hickman arm, 28% of the devices were removed prematurely due to a complication compared with 4% in the TIVAS arm. Quality of life based on the device-specific questionnaire was greater in the TIVAS arm for 13 of the 16 questions. The economic evaluation showed that Hickman arm was associated with greater mean cost per patient £1803 (95% CI 462, 3215), but similar quality-adjusted life years -0.01 (95% CI -0.15, 0.15) than the TIVAS arm. However, there is much uncertainty associated with the results. CONCLUSIONS: Compared with Hickman catheters, TIVAS may be the cost-effective option. A larger multicentre trial is needed to confirm these preliminary findings.

Using viromes to predict novel immune proteins in non-model organisms.

Immunity is mostly studied in a few model organisms, leaving the majority of immune systems on the planet unexplored. To characterize the immune systems of non-model organisms alternative approaches are required. Viruses manipulate host cell biology through the expression of proteins that modulate the immune response. We hypothesized that metagenomic sequencing of viral communities would be useful to identify both known and unknown host immune proteins. To test this hypothesis, a mock human virome was generated and compared to the human proteome using tBLASTn, resulting in 36 proteins known to be involved in immunity. This same pipeline was then applied to reef-building coral, a non-model organism that currently lacks traditional molecular tools like transgenic animals, gene-editing capabilities, and in vitro cell cultures. Viromes isolated from corals and compared with the predicted coral proteome resulted in 2503 coral proteins, including many proteins involved with pathogen sensing and apoptosis. There were also 159 coral proteins predicted to be involved with coral immunity but currently lacking any functional annotation. The pipeline described here provides a novel method to rapidly predict host immune components that can be applied to virtually any system with the potential to discover novel immune proteins.
