The effect of environmental and anthropogenic factors on the microbiome of the sponge, Halichondria panicea, at three coastal sites with different bathing water quality in North east England

Aquatic Sciences, Journal Year: 2024, Volume and Issue: 87(1)

Published: Oct. 26, 2024

Abstract The breadcrumb sponge, Halichondria panicea , is a cosmopolitan marine species. Life functions, such as feeding, metabolism and defence, are maintained through microbial symbiosis. As such, perturbations to the symbiotic balance can be expected affect health survival of sponge. Although generally tolerant environmental variables, temperature, pH salinity, responses anthropogenic factors poorly understood. In this study, community H . was examined over course 1 year. Sponge seawater samples were collected in January, April, July October 2022, from three locations with different levels bathing water quality, according UK’s Environment Agency. Samples sequenced using 16S ribosomal RNA (rRNA) gene, amplicon sequence variants (ASVs) inferred generated data. Differences bacterial diversity abundance among sponge examined.

Molecular investigation of waterborne protozoan contamination using marine Demospongiae

Ecological Indicators, Journal Year: 2023, Volume and Issue: 158, P. 111298 - 111298

Published: Nov. 25, 2023

Sponges play important role within aquatic ecosystems due to their diverse abilities including filter-based feeding mechanisms. Hence, this study evaluated the potential use of sponges as ecological biomonitors for water safety surveillance, especially in presence Waterborne protozoan pathogens WBPP. Sponge specimens were collected from different Qatari marine and subjected gDNA extraction real-time PCR using specific primer sets most common Two coastal found be positive Blastocystis sp., one sponge was Dientamoeba fragilis offshore site. No Cryptosporidium spp., Giardia duodenalis, nor Toxoplasma gondii detected. Further genotyping analysis revealed that sp. samples subtype ST3 (allele 34), which matched local clinical isolates D. specimen unambiguously clustering with Genotype 2. In conclusion, demonstrates WBPP screening provide insights into these widespread transmission terrestrial organisms human.

The microbiome of the sponge Aplysina caissara in two sites with different levels of anthropogenic impact

FEMS Microbiology Letters, Journal Year: 2023, Volume and Issue: 370

Published: Jan. 1, 2023

Abstract Despite the important roles that marine sponges play in ecosystem functioning and structuring, little is known about how sponge holobiont responds to local anthropogenic impacts. Here we assess influence of an impacted environment (Praia Preta) on microbial community associated with endemic Aplysina caissara comparison a less-impacted area do Guaecá) from coast São Paulo state (Brazil, southwestern Atlantic coast). We hypothesized impacts will change microbiome A. assembly be driven by different process (i.e. deterministic versus stochastic) under distinct levels impact. The at amplicon sequence variants level was found statistically between sites, this also seen for communities surrounding seawater sediments. Microbial both sites were assembled processes, even though presented impacts, showing pivotal role host selecting its own microbiome. Overall, study revealed altered caissara; however, processes are largely determined host.

Does the microbial community play a role in the different colour morphs of the breadcrumb sponge Halichondria panicea?

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Halichondria panicea has two different seasonal colours, green and yellow, which may reflect the effect of temperature on abundance microalgal species. There is, however, no definitive identification strain responsible for colour change. This question was addressed by metagenomic analysis 16S 18S rRNA V4 regions comparison chlorophyll fluorescence morphs epifluorescence microscopy. H. samples were collected in four seasons 2022 along Northumberland coast, North East England. The concentration sponges higher than yellow sponges. Moreover, bacterial cyanobacterial abundance, diversity, predicted functions significantly morph. eukaryotic community contained an specific genera abundance. Interestingly, had a golden-brown dinoflagellates known as Dino-Group-I-Clade-I genus. These exhibit parasitic behaviour marine organisms. It is suggested, therefore, that sign diseased rather A comprehensive sequences from sponge their provided deeper understanding variations.
