For the past 42 years, my journey has been cradled and embraced by the unwavering love and devotion of my wife IdaMarie. Without her constant inspiration and clarity of vision, this effort and life’s true essence would be without meaning. My daughters Laura and Rina, soninlaw Robert and grandchildren Lauren, Vincent, and Camille continue to illuminate my days with the radiance of their being. Lastly, to my parents Lili and Salvatore, although deceased, for the humanity that, through poverty and perseverance, distinguished their lives and transcends time. Page 7 Foreword In this text, An Atlas of the Clinical Microbiology of Infectious Diseases, Volume 1, Bacterial Agents, Dr Edward J.Bottone has done practicing clinical microbiologists a huge service. Drawing on over 35 years of experience, he has compiled an extraordinary collection of photos and photomicrographs pertaining to the laboratory diagnosis of a vast number of different bacterial infectious disease problems. The material is presented in a coherent and logical manner. The quality of the images in this Atlas is exceptional. As an added feature, pursuant to each pathogen, Dr Bottone provides text which clearly and concisely delineates important features related to cellular and colony morphology, growth patterns, microbiological characteristics, pathogenesis and disease manifestations. The practice of clinical microbiology during the past 20 years has undergone remarkable change. What was once strictly a manual endeavor, more art than science, has increasingly embraced various forms of instrumentation in the daytoday provision of diagnostic services. This trend will certainly continue as we enter the exciting new age of molecular infectious disease diagnosis. Unfortunately, largely as a consequence of increased reliance on instrumentation and other forms of technology, expertise in more traditional aspects of clinical microbiology, such as use of cellular and colony morphology as means for presumptive if not definitive microorganism identification, has clearly eroded. This reality is problematic in so far as morphology remains the cornerstone of the laboratory diagnosis of infectious diseases. An Atlas of the Clinical Microbiology of Infectious Diseases represents an elegant reminder of this reality. This text will quickly become an invaluable and practical resource for individuals working in clinical microbiology laboratories. An Atlas of the Clinical Microbiology of Infectious Diseases is one of those books that will not collect dust on the shelf; it will be referred to constantly in the laboratory. In addition, training programs for medical technologists, pathology residents and infectious disease fellows will undoubtedly lean heavily on this text as an important tool for teaching. Dr Bottone is to be commended on this wonderful addition to the clinical microbiology literature. Gary V.Doern, PhD September, 2003 Page 8 This page intentionally left blank.

Actinomyces may also colonize the vagina and gastrointestinal tract. Actinomycosis is a chronic disease caused by several species of Actinomyces, the most common of which are A. israelii, A. gerencseriae, A. naeslundi, A. viscosus, A. odontolyticus and A. meyeri. Actinomycosis develops when the microorganism is introduced into surrounding tissue and is characterized by the formation of suppurative abscesses that usually result in draining sinuses. Because of radial growth of the bacterium, colonies form in tissue, surrounded by a marked inflammatory response which gives rise to firm yellowish granules (‘sulfur granules’). These may be extruded with draining pus. While three major categories of infection (cervicofacial, thoracic, abdominal) are well recognized, actinomycosis may develop in any organ or body site, e.g. the eye (lacrimal canaliculitis) and the female pelvis in association with the presence of an intrauterine contraceptive device. Actinomycosis may occur in conjunction with other bacterial species such as Actinobatillus actinomycetemcomitans and Eikenella corrodens. Morphology Actinomyces (‘ray fungus’) species are Grampositive bacteria that occur as branching, beaded, filamentous rods which fragment into short ‘diphtheroid’ and coccoid forms. Often, the filaments of A. israelii have a swollen, clubbed terminus. Culture characteristics Actinomyces species are microaerophilic to anaerobic. The optimum temperature for growth is 37°C. With the exception of A. viscosus and A. neuii, Actinomyces species are catalasenegative. Proprionibacterium acnes, however, a Grampositive anaerobic bacterium which resides on the human skin, and which also forms branching bacillary forms, is also catalasepositive and must be differentiated from A. viscosus and A. neuii. BACILLUS SPECIES Members of the genus Bacillus are Grampositive to Gramvariable, aerobic, rodshaped bacteria which Figure 1 Actinomyces Gram stain of cervicofacial abscess drainage showing beaded filaments and filament fragments, many of which are slightly curved with clubbed ends bearing a morphological resemblance to Corynebacterium (‘diphtheroids’) species
