This study was an attempt to develop a fluorescent-antibody (FA) test to differentiate Actinomyces israelii and A. naeslundii as an aid in their laboratory identification. Two strains of A. israelii (X522 and A601) and two strains of A. naeslundii (X454 and X600), which had received intensive study by several investigators, were used for the immunization of rabbits. Working titers, based on tes...

disease caused by Actinomyces israelii and characterized by the formation of multiple abscesses, draining sinuses, granulation and fibrous tissues (1, 2). The clinical and radiologic findings of actinomycosis can often overlap with those of other chronic inflammatory or neoplastic lesions, and actinomycosis is still difficult to diagnose radiologically during its early stage (1, 3, 4). Several ...

Actinomycosis is a chronic suppurative granulomatous infection of subcutaneous tissues caused by bacterium Actinomyces israelii. It is a normal commensal of the oral cavity, gastrointestinal tract, respiratory tract, and vagina. Infection is first established locally by breach of mucosal barrier during various procedures, aspiration, trauma, or human bite. Rarely, it may spread through hematoge...

Actinomycosis is a bacterial infection due to Actinomyces israelii, a gram-positive, anaerobic organism that normally affects the cervicofacial region. However, facial injury or trauma (i.e., dental procedures) can allow this bacteria to inhabit other regions. There have been rare reports of actinomycosis of the paranasal sinuses. We present a case of a 50-year-old female who originally present...

0.1 The purpose of this paper is to describe the Hebrew infinitive (henceforth: INF) in its function as a complement that completes a predicate of incomplete predication. The description applies to the INF in Israeli Hebrew (IH) only, and is based on research of a very limited corpus. We have collected 2022 occurrences of INF from different levels of IH, which are derived from a controlled and ...
