Cardiobacterium hominis is a member of the HACEK (Haemophilus sp., Actinobacillus actinomycetemcomitans, C. hominis, Eikenella corrodens, and Kingella kingae) group commonly associated with endocarditits and is normally present in the respiratory tract. We describe the first case of acute dacryocystitis with lacrimal abscess caused by C. hominis along with a brief review of the literature. The ...

The purpose of this study was to analyze antigens of Actinobacillus actinomycetemcomitans. Fifteen hybridomas producing monoclonal antibodies (MAbs) against A. actinomycetemcomitans strain Y4 were obtained. These hybridomas were divided into three groups (Group 1, Group 2 and Group 3) on their MAbs' specificity. The MAbs (MAb S1-S8) produced by Group 1 hybridomas reacted with serotype b-specifi...
