This is the first report of Actinomyces europaeus bacteraemia in a 53-year-old man. The bacteraemia was the result of a breast abscess. Identification was established by matrix-assisted desorption ionization-time of flight mass spectrometry and confirmed by 16S rRNA gene sequencing. The patient was treated with surgical drainage and penicillin for 4 weeks; the patient did not experience any relapse during 6 months of follow-up.

Actinomyces europaeus was first described in 1997 as a new species causing predominantly skin and soft-tissue infections. Mastitis due to A. europaeus is an unusual condition. This article reports a case of primary breast abscess caused by A. europaeus in a postmenopausal woman.

Surgical Neurology International 2019Recurrent intracranial abscesses secondary to refractory otitis media present a challenge which demands multidisciplinary collaboration.
BACKGROUND
Recurrent intracranial abscesses secondary to refractory otitis media present a challenge which demands multidisciplinary collaboration.
CASE DESCRIPTION
We present the first known case of pediatric brain abscess caused by a polymicrobial infection of , , and mixed anaerobic species resulting from acute-on-chronic suppurative left otitis media. This patient required two separate stereotactic abscess drainages and a complex course of antibiotics for successful management.
CONCLUSION
Surgery is essential in the management of cerebral abscess both in agent identification and therapeutic drainage. Management of abscesses secondary to unusual and polymicrobial organisms often requires consultation from other medical and surgical specialties.

Laboratory-scale reactors treating food industry waste were used to investigate the effects of additions of cobalt (Co), nickel/molybdenum/boron (Ni/Mo/B) and selenium/tungsten (Se/W) on the biogas process and the associated microbial community. The highest methane production (predicted value: 860 mL g(-1) VS) was linked to high Se/W concentrations in combination with a low level of Co. A combination of quantitative real-time PCR of 16S rRNA genes, terminal restriction fragment length polymorphism (T-RFLP) and clone library sequencing was used for the community analysis. The T-RFLP data show a higher diversity for bacteria than for archaea in all the treatments. The most abundant bacterial population (31-55% of the total T-RFLP fragments' intensity) was most closely related to Actinomyces europaeus (94% homology). Two dominant archaeal populations shared 98-99% sequence homology with Methanosarcina siciliae and Methanoculleus bourgensis, respectively. Only limited influence of the trace metal additions was found on the bacterial community composition, with two bacterial populations responding to the addition of a combination of Ni/Mo/B, while the dominant archaeal populations were influenced by the addition of Ni/Mo/B and/or Se/W. The maintenance of methanogenic activity was largely independent of archaeal community composition, suggesting a high degree of functional redundancy in the methanogens of the biogas reactors.
