We present here the complete genome sequence of Trueperella pyogenes UFV1. The 2.3-Mbp genome contains an extremely interesting AI-2 transporter and processing system related to the quorum-sensing signal response. This specific feature is described in this species for the first time and might be responsible for a new pathogenic behavior.

In the first 2-3 weeks after parturition >90% of dairy cows will have some form of uterine infection. Uterine contamination with pathogens, such as Trueperella (formerly Arcanobacterium) pyogenes increases the risk of developing more severe endometritis, which can reduce conception rates. In this study, we compared the uterine proteome of cows infected with Trueperella pyogenes with that of uni...

Dairy cow mastitis is an important disease in the dairy industry. Different microbial species have been identified as causative agents in mastitis, and are traditionally diagnosed by bacterial culture. The objective of this study was to use metagenomic pyrosequencing of bacterial 16S rRNA genes to investigate bacterial DNA diversity in milk samples of mastitic and healthy dairy cows and compare...

Two strains of Trueperella (Arcanobacterium) pyogenes previously isolated from lung abscesses of two camels (Camelus dromedarius) in Jordan were identified phenotypically, by MALDI-TOF MS analysis and genotypically using T. (A.) pyogenes 16S-23S rDNA intergenic spacer region (ISR) and T. (A.) pyogenes superoxide dismutase A encoding gene sodA specific oligonucleotide primers. Both isolates coul...

The main factors affecting the outcome of Trueperella pyogenes (T. pyogenes) mastitis were examined through a survey of diagnostic data and interviews relating to the occurrence of T. pyogenes mastitis in 83 quarters from 82 Holstein cows between August 2012 and April 2014. Ultimately, one cow was sold during the examination, and 82 quarters from 81 cows were used for analysis on prognosis. T. ...

ABST RACT Trueperella pyogenes (formerly Arcanobacterium pyogenes) is a commensal bacterium present on the upper respiratory and urogenital tract mucosa of domestic and wild animals. It is also the most common opportunistic pathogen and isolated from the infections of cattle such as mastitis, metritis, arthritis and pneumonia. The aim of this study was to determine virulence genes (plo, nanH, n...
