Investigating the influence of <i>Diadematidae</i> scuticociliatosis on host microbiome composition Open
Mass mortality of Diadematidae urchins, caused by the Diadema antillarum scuticociliatosis Philaster clade (DScPc) , affected the Caribbean in spring 2022 and subsequently spread to the eastern Mediterranean, Red Sea, and western Indian Oc…

Detection of the Diadema antillarum scuticociliatosis Philaster clade on sympatric metazoa, plankton, and abiotic surfaces and assessment for its potential reemergence Open
A ciliate belonging to the Diadema antillarum scuticociliatosis (DaSc)-associated Philaster clade (DaScPc) caused catastrophic long-spined urchin mass mortality in spring and summer of 2022. The ciliate can be grown in culture in both the …

Viral metagenomic investigation of two Caribbean echinoderms, <i>Diadema antillarum</i> (Echinoidea) and <i>Holothuria floridana</i> (Holothuria) Open
Background Echinoderms play crucial roles in coral reef ecosystems, where they are significant detritivores and herbivores. The phylum is widely known for its boom and bust cycles, driven by food availability, predation pressure and mass m…

Transglobal spread of an ecologically relevant sea urchin parasite Open
Mass mortality of the dominant coral reef herbivore Diadema antillarum in the Caribbean in the early 1980s contributed to a persistent phase shift from coral- to algal-dominated reefs. In 2022, a scuticociliate most closely related to Phil…

Dynamics of the Apostichopus californicus-associated flavivirus under suboxic conditions and organic matter amendment Open
Flaviviruses cause some of the most detrimental vertebrate diseases, yet little is known of their impacts on invertebrates. Microbial activities at the animal-water interface are hypothesized to influence viral replication and possibly con…

Design and validation of a PCR protocol to specifically detect the clade of<i>Philaster</i>sp. associated with<i>Diadema antillarum</i>scuticociliatosis Open
Diadema antillarum scuticociliatosis (DaSc), caused by a scuticociliate closely related to Philaster apodigitiformis , has affected Caribbean long-spined urchins since at least January 2022. Quantitative PCR (qPCR) is currently the standar…

A scuticociliate causes mass mortality of <i>Diadema antillarum</i> in the Caribbean Sea Open
Echinoderm mass mortality events shape marine ecosystems by altering the dynamics among major benthic groups. The sea urchin Diadema antillarum , virtually extirpated in the Caribbean in the early 1980s by an unknown cause, recently experi…

Unique Features of the Gut Microbiome Characterized in Animal Models of Angelman Syndrome Open
Angelman syndrome (AS)-associated gastrointestinal (GI) symptoms significantly impact quality of life in patients. In AS models in mouse, rat, and pig, AS animals showed impaired colonization of the gut microbiota compared to wild-type (he…

Oral microbiota and periodontitis severity among Hispanic adults Open
Background Periodontitis, one of the most common bacterial infections characterized by chronic inflammation, is also known to be a risk factor for chronic conditions, including cardiovascular disease and cancer. This inflammation is driven…

Unique features of the gut microbiome characterized in animal models of Angelman Syndrome Open
A large subset of patients with Angelman syndrome (AS) suffer from concurrent gastrointestinal (GI) issues, including constipation, poor feeding, and reflux. AS is caused by the loss of ubiquitin ligase E3A ( UBE3A ) gene expression in the…

The Bacterial and Fungal Gut Microbiota of the Greater Wax Moth, Galleria mellonella L. Consuming Polyethylene and Polystyrene Open
Plastic production has been increasing exponentially in the last 60 years, but plastic disposal is out of control, resulting in the pollution of all ecosystems on Earth. Finding alternative environmentally sustainable choices, such as biod…

Soy and Frequent Dairy Consumption with Subsequent Equol Production Reveals Decreased Gut Health in a Cohort of Healthy Puerto Rican Women Open
The U.S. Hispanic female population has one of the highest breast cancer (BC) incidence and mortality rates, while BC is the leading cause of cancer death in Puerto Rican women. Certain foods may predispose to carcinogenesis. Our previous …

Geology and climate influence rhizobiome composition of the phenotypically diverse tropical tree Tabebuia heterophylla Open
Plant-associated microbial communities have diverse phenotypic effects on their hosts that are only beginning to be revealed. We hypothesized that morpho-physiological variations in the tropical tree Tabebuia heterophylla, observed on diff…
