Isolation of Wolinella recta and Actinomyces viscosus from an actinomycotic chest wall mass

Abstract

In this Note we describe a patient with an actinomycotic chest wall mass from which large numbers of Wolinella recta and Actinomyces viscosus organisms were isolated. This is the first reported association of W. recta with extraoral infection and the tenth report of lung infection by A. viscosus.

Campylobacter rectus in human periodontitis

“…C rectus has been recovered in high levels extraorally from a lung infeetion (61) and intraorally from necrotic root canal infections (18,50,62,67), infec-tious implant failure (peri-implantitis) (2, 52), progressive adult periodontitis (1, 8, 9, 19-21, 28, 64, 65), localized juvenile periodontitis (36,54) and periodontitis in patients with inflammatory bowel disease (70), diabetes mellitus (32,72) and human immunodeficiency virus infection (38,39,47,73). The organism is an infrequent isolate of supra-and subgingival plaque assoeiated with periodontal health and gingivitis (28,29,37), To clarify further the periodontopathie potential of C rectus, this study determined the age and sex distribution of C rectus in 1654 periodontitis patients, the relationship between C. rectus and disease-aetive periodontitis in 93 adult periodontitis padents on maintenance therapy, the effects of periodontal debridement on subgingival C, rectus counts in 20 adult periodontitis patients and the in vitro antimicrobial susceptibility of 230 periodontal isolates to tetracyeline, metronidazole, penicillin and ciprofioxacin.…”

Pelvic Peritonitis Caused by Campylobacter rectus Infection: Case Report and Literature Review

“…As a whole, 15 cases of extra-oral infections with CR were reported in published clinical data, affecting different tissues (Table 1) [4][5][6][7][8][9][10][11][12][13][14][15][16]. The patient's recovery mainly depends upon his general health condition, the site affected by the infection but also a quick identification of CR and the provision of a proper and efficient treatment.…”

“…The patient's recovery mainly depends upon his general health condition, the site affected by the infection but also a quick identification of CR and the provision of a proper and efficient treatment. The identified risk factors associated with an extra-oral infection with CR are a lack of oral hygiene, a periodontal disease or a dental abscess [4][5][6][7][8][9][10]. They can be aggravated by immunosuppression induced by health reasons that could potentiate conditions such as diabetes, chronic alcoholism, a cancerous pathology, a kidney failure or neutropenia [4,6,8,[10][11][12].…”

“…Even if the hypothesis of a contamination of periodontal origin is the most probable, the concept of a focal infection remains disputable since it is difficult to absolutely prove that an extra-buccal infection has been caused by bacteria from the oral cavity. Animal experimentation and clinical studies put forward several physiopathological mechanisms: bacteremia, intervention of toxins, immunologic mechanisms and/or swallowing of dental plaque [4,17]. However, it remains difficult to isolate at the same time the same bacteria in the oral cavity and in the infected site with a positive biological analysis.…”

Thoracic Actinomycosis

“…Actinomyces israelii is the most common species causing human disease. Other pathogenetic species include Actinomyces naeslundii, 1 Actinomyces viscosus, 2 Actinomyces odontolyticus, Actinomyces meyeri, [3][4][5][6] and A. propionica 7 . Interestingly, Actinomyces bovis is a common pathogen in cattle but does not cause human disease, whereas A. israelii does not infect cattle.…”
