"Although a sample of the vast oral microbiota (Moore and Moore, 1994) can infect the exposed tooth pulp, culture studies have long established that only a subset of oral microflora, consisting of a limited number of species, is consistently isolated from such root canals. The root canal flora of teeth with clinically intact crowns, but having necrotic pulps and diseased periapices, is dominated (> 90%) by obligate anaerobes (Sundqvist, 1976; Byström and Sundqvist, 1981; Haapasalo, 1989; Sundqvist et al., 1989), usually belonging to the genera Fusobacterium, Porphyromonas (formerly Bacteroides; Shah and Collins, 1988), Prevotella (formerly Bacteroides; Shah and Collins, 1988), Eubacterium, and Peptostreptococcus. In contrast, the microbial composition—even in the apical third of the root canal of periapically affected teeth with pulp canals exposed to the oral cavity—is not only different from but also less dominated (< 70%) by strict anaerobes (Baumgartner and Falkler, 1991). Using culture techniques (Hampp, 1957; Kantz and Henry, 1974; Dahle et al., 1996), dark-field (Brown and Rudolph, 1957; Thilo et al., 1986; Dahle et al., 1993), and transmission electron microscopy (Nair, 1987), investigators have found spirochetes in necrotic root canals. Culture studies (for review, see Waltimo et al., 2003) and the application of scanning electron microscopy (Sen et al., 1995) have revealed the presence of fungi"
Т.е. Fusobacterium, Porphyromonas (formerly Bacteroides; Shah and Collins, 1988), Prevotella (formerly Bacteroides; Shah and Collins, 1988), Eubacterium, and Peptostreptococcus. - достаточно ограниченный спектр микробов характерных для колонизации в виде биопленок и прочее.
У Алекса были обнаружены именно Fusobacterium, т.е. метаболиты характерные для нее.
Интересно было было провериться на плазму.
