In these cases, the most frequent anaerobic bacteria isolated from clinical specimens were Fusobacterium nucleatum (n = 18), Peptostreptococcus anaerobius (n = 11), Prevotella oralis (n = 10), Prevotella melaninogenica (n = 7), Prevotella loescheii (n = 7), and Bacteroides pyogenes (n = 7).
Blood cultures drawn were positive for gram positive cocci and gram negative rods within 18 hours of collection, which eventually speciated into viridans streptococci and Prevotella oralis. Following initial identification, a CT scan of the abdomen obtained showed pan colonic diverticulosis with a terminal ileal collection concerning diverticular phlegmon associated with extensive superior mesenteric vein thrombosis concerning an infected thrombophlebitis.
The following species were eliminated: Gram(+) anaerobes: Clostridium sporogenes, Eubacterium saburreum, and Lactobacillus fermentum, and Gram(-) anaerobes: Bacteroides ovatus, Bacteroides uniformis, Fusobacterium mortiferum, and Prevotella oralis, as well as Gram(+) aerobic bacterium Staphylococcus aureus MSSA.
