“…The three sponge species, seawater, and sediment samples were collected along the north coast of São Paulo state (São Sebastião, Brazil). This region is characterized by the transition between tropical and temperate southwestern Atlantic marine ecoregions ( Spalding et al, 2007 ) and encompasses over 70 sponge species belonging to the classes Calcarea and Demospongiae ( Custódio and Hajdu, 2011 ). It could be considered a local hotspot of sponge diversity in Brazil.…”

Marine sponges are known to harbor a diverse and complex microbiota; however, a vast majority of surveys have been investigating the prokaryotic communities in the north hemisphere and Australia. In addition, the mechanisms of microbial community assembly are poorly understood in this pivotal player of the ecosystem. Thus, this survey addressed the holobiome of the sponge species in the São Paulo region (Brazil) for the first time and investigated the contribution of neutral and niche processes of prokaryotic, fungal, and unicellular eukaryotic assemblage in three sympatric species Aplysina caissara, Aplysina fulva, and Tedania ignis along with environmental samples. The compositions of the holobiome associated with the sponges and detected in environmental samples were strikingly different. Remarkably, between 47 and 88% of the assigned operational taxonomic units (OTUs) were specifically associated with sponge species. Moreover, around 77, 69, and 53% of the unclassified OTUs from prokaryotic, fungal, and unicellular eukaryotic communities, respectively, showed less than 97% similarity with well-known databases, suggesting that sponges from the southwestern Atlantic coast are an important source of microbial novelty. These values are even higher, around 80 and 61% of the unclassified OTUs, when excluding low abundance samples from fungal and unicellular eukaryotic datasets, respectively. Host species were the major driver shaping the sponge-associated microbial community. Deterministic processes were primarily responsible for the assembly of microbial communities in all sponge species, while neutral processes of prokaryotic and fungal community assembly were also detected in the sympatric A. caissara and T. ignis replicates, respectively. Most of the species-rich sponge-associated lineages from this region are also found in the Northern seas and many of them might play essential roles in the symbioses, such as biosynthesis of secondary metabolites that exhibit antimicrobial and antiviral activities, as well as provide protection against host predation. Overall, in this study the microbiota was assembled by interactions with the host sponge in a deterministic-based manner; closely related sponge species shared a strong phylogenetic signal in their associated prokaryotic and fungal community traits and Brazilian sponges were a reservoir of novel microbial species.

“…Brazil has a quite representative fauna of freshwater Porifera, with 52 of the 200 species described worldwide (Custódio & Hajdu, 2011). In several areas, these animals are an important fraction of the invertebrate biomass, known as cauxi by the local populations, and recognized as the cause of dermatitis and other health problems (Volkmer-Ribeiro et al , 2006; Cruz et al ., 2013).…”

Reduction of RBL–2H3 cells degranulation by nitroaromatic compounds from a Bacillus strain associated to the Amazonian sponge Metania reticulata

Symbionts in sponges must interact with the host immune system, and this can be mediated by immunomodulators. As the bases of the immune system in sponges resemble those of higher metazoans, it is possible that compounds from this microbiota show similar effects in other phyla. It is also known that several antibiotics, in special macrolides, can modulate many components of the immune response and sponges and their associated microorganisms are a rich source of these compounds. Therefore, we tested the immunosuppressive capacity of antibiotic substances produced by bacterial and fungal strains isolated from the Amazon freshwater sponge Metania reticulata. Fourteen bacterial and six fungal strains were obtained from samples of M. reticulata collected in the Negro River (Amazon Central Basin region), during the dry season. These cultures were monitored for natural antimicrobial activity, and two Bacillus strains (MERETb.761 and MERETb.762) and one fungus (MERETf.010) were selected. One Bacillus strain, MERETb.762, showed strong and specific antibiosis on Staphylococcus aureus and two fractions of its extract inhibited the degranulation of RBL–2H3 cells. The predicted formulas of these fractions were C12H6N4O8 and C25H4N2O6, both corresponding to nitroaromatic compounds.

“…Vários grupos foram redescritos em estudos recém-publicados, com notícias de novos registros de espécies, contribuindo, desse modo, para um conhecimento mais sólido da fauna sul-americana de esponjas com ocorrência em ecossistemas aquáticos continentais brasileiros. Para a região Centro-Oeste do Brasil, Batista e Volkmer--Ribeiro (2002) Custódio & Hajdu (2011) comentam que as esponjas são historicamente consideradas um grupo de taxonomia complexa, sendo comuns discussões em torno da sua sistemática. Disto decorre que muitos grupos ainda não possuem uma posição taxonômica precisamente definida, havendo problemas de sinonímia e com chaves de identificação, cenário que orienta para a necessidade de contínua e profunda revisão dos táxons julgados válidos, objetivando assim uma base taxonômica mais sólida.…”

This work presents an updated review of scientific studies involving the fauna of freshwater sponges in South America, especially of studies conducted in Brazil. A study was conducted of the scientific production regarding the occurrence and distribution of freshwater sponges, and of the use of their siliceous spicules, preserved in sedimentary deposits, as proxy for paleoenvironmental reconstruction studies. The studies are relatively more developed in the South-Central and North of the country. However, it is evident that there is a need for more comprehensive and intensive studies of the description of current species and their identification in sedimentary sequences. IntroduçãoAs esponjas são animais exclusivamente aquá-ticos (marinhos e/ou dulciaquícolas) membros do filo Porifera. São metazoários, de vida bentônica séssil, que vivem aderidos a substratos rochosos ou mesmo sobre restos de vegetação submersa, incrustando raízes de macrófitas, galhos ou troncos de árvores em regiões que sofrem inundações sazonais, como nas várzeas dos grandes rios amazônicos (Volkmer-Ribeiro 1999, Volkmer-Ribeiro e Pauls 2000). Uma característica fundamental comum a todas as esponjas é sua função filtradora, atuando no meio aquático como verdadeiras bombas aspirante-prementes, uma vez que a água do ambiente é absorvida pelos poros, filtrada nas câmaras coanocitárias e expelida novamente para o meio aquático através dos ósculos, orifícios de saída de água (Volkmer-Ribeiro e Parolin 2010). O esqueleto das esponjas é constituído por espículas (silicosas ou carbonáticas) que ao entrelaçarem-se formam uma trama complexa que dá sustentação ao corpo principal e proporciona uma estrutura de sustentação para as células vivas do animal.Este trabalho atualiza o estado da arte das principais pesquisas sobre o registro e ocorrência de esponjas de água doce na América do Sul, com destaque para o Brasil, assim como da sua utilização como dado proxy em estudos de reconstrução paleoambiental, através das espículas presentes em colunas de sedimentos, sendo observadas majoritariamente em depósitos lacustres do Quaternário.Até a primeira metade do século XX, os levantamentos e descrições da fauna de esponjas continentais brasileiras eram escassos e incipientes, atingindo maior notoriedade e repercussão no meio científico a partir da década de 1960, incluindo as pesquisas operadas por um considerável número de especialistas dedicados ao estudo e compreensão dessas comunidades bênticas. Por sua vez, a produção científica relativa à utilização de espículas de esponjas continentais como indicadoras de condições paleoambientais, adquiriu maior regularidade na segunda metade do século XX, com a intensificação das investigações no início do século XXI, destacando-se as abordagens principalmente na região Centro-Sul e Norte do Brasil.
