The Nuclear and Mitochondrial Genomes of Amoebophrya sp. ex Karlodinium veneficum.

Dinoflagellates are a diverse group of microplankton that include free-living, symbiotic, and parasitic species. Amoebophrya, a basal lineage of parasitic dinoflagellates, infects a variety of marine microorganisms, including harmful-bloom-forming algae. Although there are currently three published Amoebophrya genomes, this genus has considerable genomic diversity.

Tracking the sources of Leptospira and nutrient flows in two urban watersheds of Puerto Rico.

This study investigated the relationship between nutrient levels, source of fecal contamination, and pathogenic Leptospira in Puerto Rico's northern coast and San Juan Bay Estuary (SJBE) aquatic ecosystems. Microbial source tracking (MST) was also used to investigate the connections between sources of feces contamination and the presence of Leptospira. Eighty-seven water samples were collected during the June (n=44) and August (n=43) in 2020.
