New article in the Journal of Dairy Science about the bacterial microbiome in the rumen of cows – 9.11.2016

 8

The bacterial community attached to the rumen epithelium in cattle was evaluated using high-throughput sequencing in a long-term feeding experiment that started with forage-only feeding, followed by 1-wk gradual adaptation and subsequent 4-wk 60% grain feeding challenge. Cows responded differently to same grain-rich diet, with 4 cows experiencing and other 4 cows not experiencing subacute ruminal acidosis. The feeding of 60% grain for 4-wk caused major changes in the microbial community and lowered the diversity of the epimural bacterial community in the rumen of cows, independent of ruminal pH responses during the feeding challenge.

The publication arose from a collaboration project between the Institute of Animal Nutrition and Functional Plant Compound and the Institute of Milk Hygiene.

The Garant publication award, endowed with 3,000€, was created to support outstanding and innovative research in animal nutrition for wildlife and farm animals. The publication “Mucosa-associated bacterial microbiome of the gastrointestinal tract of weaned pigs and dynamics linked to dietary calcium-phosphorus”, first authored by Evelyne Mann-Selberherr, was selected for the Garant publication award 2016. The publication arose from a collaboration project between the Institute of Milk Hygiene, Institute of Animal Nutrition and Functional Plant Compounds and the Clinic for Swine under the supervision of Barbara Metzler-Zebeli.

New article in Meat science about the bacterial spoilage on slaughter pig musculature - 22.02.2016

 11

The spoilage of carcass halves during pig slaughter can be considered as highly complex. It represents a unique mixture of microbes that origin from the animal itself and microbes deriving from the slaughter equipment and environment. The aim of this study was to disentangle the microbial diversity on porcine musculature samples directly after slaughter. A diverse microbial composition with 54-159 OTUs was detected in all samples. Interestingly, 6 out of 8 samples were strongly dominated by 1-2 highly abundant OTUs with >10% relative abundance. Aeromonas, Pseudomonas, Serratia and Brochothrix contributed to 38% of total microbial contamination. We conclude that psychrophile and psychrotrophic spoilers dominated the flora and that the exclusive cultivation of Enterobacteriaceae underestimates the actual contamination event.

New article in Frontiers in microbiology about epimural indicator phylotypes of SARA in cattle -19.2.2016

 13

This study aimed to investigate shifts in the bacterial epimural  microbiome of cattle during a long-term transient SARA model consisting of two concentrate-diet-induced SARA challenges separated by a one-week challenge break. The microbiome was determined using Illumina MiSeq sequencing of the 16S rRNA gene (V345 region). Species diversity estimates and evenness increased during the challenge break compared to all other sampling time points (P<0.05). During both SARA challenges, Kingella- and Azoarcus-OTUs decreased and a dominant Ruminobacter-OTU increased significantly during the challenge break. Our results show that the microbiome re-establishes the baseline conditions slower after a SARA challenge than ruminal pH. Key phylotypes that were reduced during both challenges may help to establish a bacterial fingerprint to facilitate understanding effects of SARA conditions on the microbiome and their consequences for the ruminant host. This study is part of a cooperation project between the Institute of Animal Nutrition and Functional Plant Compounds and the Institute of Milk Hygiene, Milk Technology and Food Science.
