ClearAssociation between the skin microbiome and MHC class II diversity in an amphibian
Researchers examined the relationship between skin microbiome diversity and immune gene variation in moor frog populations across different geographic regions. The study found that bacterial community composition varied significantly between regions and was correlated with genetic diversity in immune-related MHC genes. These findings suggest that historical demographic events and immunogenetic variation jointly shape microbial communities on amphibian skin, with potential implications for disease susceptibility.
Influence of host phylogeny and water physicochemistry on microbial assemblages of the fish skin microbiome
Researchers conducted a large-scale analysis of nearly 2,000 fish skin microbiome samples across 98 species to understand what factors shape microbial communities on fish surfaces. They found that host evolutionary history and water chemistry, particularly salinity and temperature, were the strongest predictors of skin microbiome composition. The study provides a broad framework for understanding how environmental stressors, including pollutants, may disrupt the beneficial microbial communities on fish.
Habitat disturbance influences the skin microbiome of a rediscovered neotropical-montane frog
Researchers studied the skin bacteria of a rediscovered montane frog in disturbed versus undisturbed habitats, finding that habitat degradation caused more chaotic and variable microbial communities — a pattern called dysbiosis. On the positive side, frogs in disturbed areas had higher levels of bacteria that may protect against the deadly chytrid fungus Bd, suggesting the frog's microbiome may be adapting to coexist with the pathogen over decades.
Anatomically-specific coupling between innate immune gene repertoire and microbiome structure during coral evolution
This study found that different coral species have distinct coupling between their immune gene repertoires and microbiome composition, suggesting evolutionary specialization of host-microbe relationships. Coral microbiomes are being disrupted by plastic pollution, making understanding baseline coral immunity relevant to assessing plastic pollution impacts on reef health.
The interplay between host-specificity and habitat-filtering influences sea cucumber microbiota across an environmental gradient of pollution
Researchers examined how environmental pollution gradients influence intra-specific variation in microbiota diversity and structure across skin, gut, sediment, and water communities associated with sea cucumbers. They found that both host-specificity and habitat-filtering interact to shape microbial communities along pollution gradients, with animal-associated microbiota showing distinct patterns compared to environmental communities.
Comparative Analysis of Gut Microbiota Provides Insights into High-altitude Adaptation in Rana kukunoris on the Qinghai-Xizang Plateau
Researchers used 16S rRNA gene sequencing to characterize and compare the gut microbiota of the high-altitude frog Rana kukunoris on the Qinghai-Xizang Plateau with two low-altitude frog species, Rana amurensis and Rana dybowskii. The comparative analysis aimed to identify microbial community differences that may reflect adaptive strategies to extreme high-altitude conditions including low oxygen and harsh temperatures.
Species-specific Microorganisms in Acid-tolerant Chironomus Larvae Reared in a Neutral pH Range under Laboratory Conditions: Single Dataset Analysis
Researchers systematically compared larval microbiomes of 11 Chironomus midge species from acidic and neutral pH environments using amplicon sequencing, finding that acid-tolerant species exhibited lower microbiome evenness and a biased abundance of specific microorganisms consistent with acid tolerance mechanisms.
The interplay between host-specificity and habitat-filtering influences sea cucumber microbiota across an environmental gradient of pollution
Researchers studied how pollution levels along a Hong Kong coastline affect the gut and skin microbiomes — communities of bacteria living on and in organisms — of a tropical sea cucumber, finding that the animal maintains its own distinct microbial community even in highly polluted areas. This suggests sea cucumbers have strong internal mechanisms that shape their microbiome independently of the surrounding environment, which may help them survive in contaminated coastal waters.
Immunological impacts of exposure to microplastic water contaminants during early development in Xenopus 2357
Researchers used Xenopus frogs—whose immune system parallels key human features—to study how early developmental microplastic exposure affects immune system development, finding disruption of both innate and adaptive immune components with potential relevance to human susceptibility to infection.
Salmo salar Skin and Gill Microbiome during Piscirickettsia salmonis Infection
Researchers used bacterial gene sequencing to examine how the skin and gill microbiome of farmed Atlantic salmon changes during infection with the pathogen Piscirickettsia salmonis. They discovered a previously undescribed core group of co-occurring bacteria, including potential secondary pathogens found on skin ulcers and gills. The findings suggest that coinfection with these additional bacteria may worsen the severity of the primary infection.
