Isolation and genome sequencing of five lytic bacteriophages from hospital wastewater in the Philippines.

Here, we report the genome sequences of five bacteriophages isolated from hospital wastewater, including two new species and two candidates for therapeutic application. No virulence, temperate marker and antibiotic resistance genes were found in the genomes of phage vB_VIPECOOM03 and phage vB_VIPKPNUMC01, making them suitable candidate for therapy.

Microbial community structure and settlement induction capacity of marine biofilms developed under varied reef conditions.

Coral larval settlement relies on biogenic cues such as those elicited by microbial biofilm communities, a crucial element of coral recruitment. Eutrophication can modify these biofilm-associated communities, but studies on how this affects coral larval settlement are limited. In this study, we developed biofilm communities on glass slides at four sites with increasing distance from a mariculture zone.

Microbiome diversity and host immune functions influence survivorship of sponge holobionts under future ocean conditions.

The sponge-associated microbial community contributes to the overall health and adaptive capacity of the sponge holobiont. This community is regulated by the environment and the immune system of the host. However, little is known about the effect of environmental stress on the regulation of host immune functions and how this may, in turn, affect sponge-microbe interactions.

Coral Gametogenesis Collapse under Artificial Light Pollution.

Artificial light at night (ALAN) can have negative impacts on the health of humans and ecosystems. Marine organisms, including coral reefs in particular, rely on the natural light cycles of sunlight and moonlight to regulate various physiological, biological, and behavioral processes. Here, we demonstrate that light pollution caused delayed gametogenesis and unsynchronized gamete release in two coral species, Acropora millepora and Acropora digitifera, from the Indo-Pacific Ocean.

The Prokaryotic Microbiome of is Stable under Short-Term Artificial Light Pollution.

Corals harbor a great diversity of symbiotic microorganisms that play pivotal roles in host nutrition, reproduction, and development. Changes in the ocean environment, such as increasing exposure to artificial light at night (ALAN), may alter these relationships and result in a decline in coral health. In this study, we examined the microbiome associated with gravid specimens of the reef-building coral We also assessed the temporal effects of ALAN on the coral-associated microbial community using high-throughput sequencing of the 16S rRNA gene V4 hypervariable region.

Population structure and microbial community diversity of two common tetillid sponges in a tropical reef lagoon.

Sponges are predicted to dominate future reef ecosystems influenced by anthropogenic stressors and global climate change. The ecological success of sponges is attributed to their complex physiology, which is in part due to the diversity of their associated prokaryotic microbiome. However, the lack of information on the microbial community of many sponge species makes it difficult to gauge their interactions and functional contributions to the ecosystem.
