Non-human microbiome, August 25, 2014

Microbiotas of pigs, two fish species in the same pond, coral-algal associations, hypersaline soil, and marine eukaryotes.

Mammal microbiome

The influence of host’s genetics on the gut microbiota composition in pigs and its links with immunity traits – J. Estellé – Proceedings, 10th World Congress of Genetics Applied to Livestock Production

“A cohort of 60-days old piglets was assessed for fecal microbiota composition by pyrosequencing of the 16S rDNA. “

Fish microbiome

* Do the intestinal microbiotas differ between paddlefish (Polyodon spathala) and bighead carp (Aristichthys nobilis) reared in the same pond? – Xuemei Li – Journal of Applied Microbiology

“After 30-days of rearing the intestinal microbiota of the two fish species were assessed by pyrosequencing of 16S rRNA genes”

Insect microbiome

Microbial Associates of the Vine Mealybug Planococcus ficus (Hemiptera: Pseudococcidae) under Different Rearing Conditions – Lilach Iasur-Kruh – Microbial Ecology

“To examine the possible role of microbial symbionts in virus transmission, the archaeal, bacterial, and fungal microbiota of field and laboratory P. ficus were characterized using molecular and classical microbiological methods. “

Coral microbiome

* The extended phenotypes of marine symbioses: ecological and evolutionary consequences of intraspecific genetic diversity in coral–algal associations – John E. Parkinson and Iliana B. Baums – Frontiers in Microbiology

“Here, we hypothesize that unique combinations of coral and algal individuals yield functional diversity that affects not only the ecology and evolution of the coral holobiont, but associated communities as well. “

Soil microbiome

Salinity-induced differences in soil microbial communities around the hypersaline Lake Urmia – Mohsen Barin – Soil Research

“We tested the hypotheses that salinity reduces microbial biomasses and change the structure of the microbial community.”

Water microbiome

Microbial Community Response to Chlorine Conversion in a Chloraminated Drinking Water Distribution System – Hong Wang – Environmental Science & Technology

“Although high throughput sequencing of 16S rRNA genes revealed a distinct community shift and higher diversity index during the chlorine burn, it steadily returned towards a condition more similar to pre-burn than burn stage.”

Metagenetic analysis of patterns of distribution and diversity of marine meiobenthic eukaryotes – Vera G. Fonseca – Global Ecology and Biogeography

“Here, we ask: (1) if the macroecology of meiobenthic communities is explained mainly by dispersal constraints or by environmental conditions; and (2) if levels of meiofaunal diversity surpass existing estimates based on morphological taxonomy.”

Microbiology of the Built Environment

* A disturbing trend – casual and reckless use of antimicrobial agents in building materials – Jonathan Eisen – MicroBEnet

“So they put in flooring that apparently was impregnated with some sort of antibacterial agent and they have no evidence that it works. “
