Microbiome digest, August 28, 2014

Cool new study today by Jack Gilbert on the bacteria living in our homes, what happens to you microbiome after you die, (gut) microbiome and respiratory diseases, lots of water studies, and Bik’s Picks.

General  human microbiome 

* Your death microbiome could catch your killer – Anna Williams – NewScientist

“These “friendly” bacteria adhere to the lining of the gut and keep the microbial villains at bay by outcompeting them. After we die, however, our gut flora have a party.“

Human respiratory microbiome

The Microbiome and the Lung – Lijia Cui – Annals of the American Thoracic Society

“In this review, we provide an overview of the basics of microbiome studies.”

Microbiome Diversity and Asthma and Allergy Risk – Antje Legatzki – Current Allergy and Asthma Reports

“In this review, we will discuss the available literature concerning the human microbiota and asthma and allergy development and occurrence. “

Gut microbiome

You waited for it: The journal Helicobacter has a Helicobacter special!
Gastric and Enterohepatic Helicobacters other than Helicobacter pylori
Armelle Ménard – Helicobacter

“Several studies highlighted the virulence of non-H. pylori species including H. cinaedi in humans and hyperlipidemic mice or H. macacae in geriatric rhesus monkeys with intestinal adenocarcinoma. “

Pregnancy and birth

Systemic Inflammation in the Extremely Low Gestational Age Newborn Following Maternal Genitourinary Infections – Raina N. Fichorova – American Journal of Reproductive Immunology

“Mothers of 914 infants born before 28th gestation week reported cervical/vaginal infection (CVI), and/or urine/bladder/kidney infection (UTI), or neither. Inflammation proteins measured in baby’s blood”

Animal models of microbiome research

Intestinal Microbial Variation May Predict Early Acute Rejection after Liver Transplantation in Rats – Ren, Zhigang – Transplantation

“cluster analysis of denaturing gradient gel electrophoresis (DGGE) profiles showed the 7AR and 3AR groups clustered together with 73.4% similarity, suggesting that intestinal microbiota was more sensitive than hepatic function in responding to AR.”

Microbiology of the built environment

* Longitudinal analysis of microbial interaction between humans and the indoor environment – Simon Lax – Science

“Microbial communities associated with seven families and their homes over 6 weeks were assessed, including three families that moved their home. “

* Sloan Microbiology of the Built Environment Data Analysis Workshop (secrets of QIIME, VAMPS and QIITA) January 6-7, 2015 – Jonathan Eisen – MicroBEnet

“to learn hands-on how to use these tools on their own data, to perform meta-analyses that combine built environment datasets“

Water microbiome

Microbial weeds in hypersaline habitats: the enigma of the weed-like Haloferax mediterranei – Aharon Oren and John E. Hallsworth – FEMS Microbiology Letters

“Here, we discuss the enigma of the less abundant Haloferax mediterranei, an archaeon that grows faster than any other, comparable extreme halophile.”

Bacterial profiling in brine samples of the Emalahleni Water Reclamation Plant, South Africa, using 454-pyrosequencing method – Sudharshan Sekar – FEMS Microbiology Letters

“A metagenomic approach was applied using 454-pyrosequencing data analysis for the profiling of bacterial communities in the brine samples of the water reclamation plant. “

The role of dispersal mode and habitat specialisation in metacommunity structuring of aquatic macroinvertebrates in isolated spring fens – Vanda Rádková – Freshwater Biology

“We applied two species categorisations, common/rare and generalists/specialists, to disentangle the roles of dispersal capacity and habitat specialisation.”

Shifts in archaeaplankton community structure along ecological gradients of Pearl Estuary – Jiwen Liu – FEMS Microbiology Ecology

“Using 454 pyrosequencing, the present study examined the archaeal communities along a subtropical estuary, Pearl Estuary, China. “

Soil microbiome

The Effects of Radiation Pollution on the Population Diversities and Metabolic Characteristics of Soil Microorganisms – Meiying Gu – Water, Air, & Soil Pollution

“Microbial diversities were determined by using methods of cultured isolates and carbon source utilization on Biolog EcoPlate™. “

Bik’s Picks

A chocolate habit in ancient North America – Michael Bawaya – Science

“the findings suggest regular trade in cacao—and movements of the people who imbued it with significance—between ancient Mesoamericans and their northern neighbors, says Dorothy Washburn, an archaeologist at the University of Pennsylvania Museum of Archaeology and Anthropology “

Babies may be good at remembering, and forgetting – Laura Sanders – Science News

“over 20 percent of 5-year-olds and 8- to 9-year olds recounted events from their first year, some from the very first months of life.”

How the zebrafish gets its stripes: Uncovering how beautiful color patterns can develop in animals – Science Daily

Three major pigment cell types, black cells, reflective silvery cells, and yellow cells emerge during growth in the skin of the tiny juvenile fish and arrange as a multi-layered mosaic to compose the characteristic color pattern. “
