Abstract
The impact of anaerobic bacteria on the human host is sparsely investigated due to cultivation challenges. Nonetheless, in the last decade increasing research demonstrated the importance of paying attention to these overlooked pathogens. In this chapter, we provide an overview of analyzing surface and intracellular inflammation markers of neutrophils and monocytes in response to Gram-positive anaerobic cocci (GPAC) species Peptoniphilus (P.) harei.

Abstract
Mediastinitis is a well-known complication of open-heart surgery. Strictly anaerobic bacteria are rarely found in this condition, unlike in descending mediastinitis. We report the case of a mediastinitis due to Prevotella buccae after surgical replacement of the aortic valve and triple coronary artery bypass in an immunocompetent 76 year-old man. The bacteria were found in pure culture on blood samples and surgical samples. This case emphasizes the need to perform anaerobic cultures in case of sternal wound infection after open-heart surgery.

Abstract
Spinal intramedullary abscesses are rare and potentially devastating lesions. Infection is mostly caused by staphylococci. Anaerobes are rare and often polymicrobial. We report an unusual case of spinal cord intramedullary abscess in a 7-month-old infant with monomicrobial infection due to Finegoldia magna. She was found to have a missed congenital thoracic dermal sinus. The patient was treated with metronidazole and ceftriaxone for 8 weeks, and improvement of the infection was documented. Clinical awareness of patients at risk is crucial for early diagnosis and intervention. As detection methods continue to improve for Finegoldia magna, it is important to increase awareness of the pathogenic role of this organism.

Abstract
An association between oral bacteria and atherosclerosis has been postulated. A limited number of studies have used 16S RNA gene sequencing-based metagenomics approaches to identify bacteria at the species level from atherosclerotic plaques in arterial walls. The objective of this study was to establish detailed oral microbiome profiles, at both genus and species level, of clinically healthy coronary and femoral artery tissues from patients with atherosclerosis. Tissue specimens were taken from clinically non-atherosclerotic areas of coronary or femoral arteries used for attachment of bypass grafts in 42 patients with atherosclerotic cardiovascular disease. Bacterial DNA was sequenced using the MiSeq platform, and sequence reads were screened in silico for nearly 600 oral species using the HOMINGS ProbeSeq species identification program. The number of sequence reads matched to species or genera were used for statistical analyses. A total of 230 and 118 species were detected in coronary and femoral arteries, respectively. Unidentified species detected by genus-specific probes consisted of 45 and 30 genera in coronary and in femoral artery tissues, respectively. Overall, 245 species belonging to 95 genera were detected in coronary and femoral arteries combined. The most abundant species were Porphyromonas gingivalis, Enterococcus faecalis, and Finegoldia magna based on species probes. Porphyromonas, Escherichia, Staphylococcus, Pseudomonas, and Streptococcus genera represented 88.5% mean relative abundance based on combined species and genus probe detections. Porphyromonas was significantly more abundant than Escherichia (i.e. 46.8% vs. 19.3%; p = 0.0005). This study provides insight into the presence and types of oral microbiome bacterial species found in clinically non-atherosclerotic arteries.

Abstract
Post-sternotomy mediastinitis, a nosocomial infection mostly caused by staphylococci, can be life-threatening. A case of mediastinitis due to Finegoldia magna after a coronary artery bypass graft surgery was reviewed. Although this bacterium is difficult to be isolated from routine blood cultures, a F. magna bacteriemia associated with mediastinitis was diagnosed.

Abstract
Among the Gram-positive anaerobic bacteria associated with clinical infections, the Gram-positive anaerobic cocci (GPAC) are the most prominent and account for approximately 25-30% of all isolated anaerobic bacteria from clinical specimens. Still, routine culture and identification of these slowly growing anaerobes to the species level has been limited in the diagnostic laboratory, mainly due to the requirement of prolonged incubation times and time-consuming phenotypic identification. In addition, GPAC are mostly isolated from polymicrobial infections with known pathogens and therefore their relevance has often been overlooked. However, through improvements in diagnostic and in particular molecular techniques, the isolation and identification of individual genera and species of GPAC associated with specific infections have been enhanced. Furthermore, the taxonomy of GPAC has undergone considerable changes over the years, mainly due to the development of molecular identification methods. Existing species have been renamed and novel species have been added, resulting in changes of the nomenclature. As the abundance and significance of GPAC in clinical infections grow, knowledge of virulence factors and antibiotic resistance patterns of different species becomes more important. The present review describes recent advances of GPAC and what is known of the biology and pathogenic effects of Anaerococcus, Finegoldia, Parvimonas, Peptoniphilus and Peptostreptococcus, the most important GPAC genera isolated from human infections.
