A case of Aggregatibacter actinomycetemcomitans endocarditis presenting as quadriceps myositis
An 80 year old female was admitted with an eight week history of fever associated with painful swelling of her right thigh, and a long history of poor dentition. Culture of blood stained fluid aspirated from the abscess grew Aggregatibacter actinomycetemcomitans (Aa) sensitive to ampicillin and cephalosporins. Transoesophageal echocardiography indicated endocarditis. Four weeks treatment with i...
متن کاملEmaA, a potential virulence determinant of Aggregatibacter actinomycetemcomitans in infective endocarditis.
The gram-negative fastidious human oropharyngeal Aggregatibacter actinomycetemcomitans is implicated in the etiology of infective endocarditis. EmaA, an oligomeric coiled-coil adhesin homologous to YadA of Yersinia enterocolitica, was hypothesized to mediate the interaction of A. actinomycetemcomitans with collagen. Collagen, the most abundant protein in human bodies and the main component of e...
متن کاملBrucellosis presenting as piriformis myositis: a case report
INTRODUCTION Myositis is a rare bacterial muscle infection. Involvement of the piriformis muscle has been rarely reported in the literature. In this report we describe a case of piriformis myositis due to Brucella melitensis, which to the best of our knowledge is the first such case presented in the literature. CASE PRESENTATION We report the case of a 19-year-old Caucasian man who presented ...
متن کاملProteomics of Aggregatibacter actinomycetemcomitans Outer Membrane Vesicles
Aggregatibacter actinomycetemcomitans is an oral and systemic pathogen associated with aggressive forms of periodontitis and with endocarditis. Outer membrane vesicles (OMVs) released by this species have been demonstrated to deliver effector proteins such as cytolethal distending toxin (CDT) and leukotoxin (LtxA) into human host cells and to act as triggers of innate immunity upon carriage of ...
متن کاملMast cells act as phagocytes against the periodontopathogen Aggregatibacter actinomycetemcomitans.
BACKGROUND Evidence to date shows that mast cells play a critical role in immune defenses against infectious agents, but there have been no reports about involvement of these cells in eliminating periodontopathogens. In this study, the phagocytic ability of mast cells against Aggregatibacter actinomycetemcomitans compared with macrophages is evaluated. METHODS In vitro phagocytic assays were ...
