ACTINOMYCOSIS Report of a Case
ACTINOMYCOSIS Report of a Case ALEJANDRO C. REYES, M.D., M.P.H. and POTENCIANO R. ARAGON, M.D., M.P.H. Institute of Hygiene University of the Philippines and EUGENIO S. DE LEON, M.D., Philips Electrical Lamps. Inc. Actinomycosis, caused by Actinomyces bovis, is a chronic granulomatous suppurative disease characterized by intensive induration and dark red discoloration, followed by develop ment of deep abscesses, which eventually rupture and leave persistent multiple draining sinuses, and the appearance of tangled mycelial masses (granules) in the discharges and in tissue sections. Actinomycosis has been reported in nearly all parts of the globe. According to Zachary Cope, the fungus has been found to be the cause of disease wherever there is a microscope and a laboratory and that the more carefully the fungus is sought, the more often it is found. Actinomycosis affects man, cattle and other animals. Ac cording to the history of this infection given by Lewis and his associates ( 4 ), the disease called "lumpy jaw'' in cattle was first described by Bollinger in 1877. Harz first described Actinomyces bovis from pathological materials obtained from a case of "lumpy jaw" in cattle and named the disease actino mycosis. He characterized the etiologic agent not by culture but by its anpearance in materials from the tissues. The tiny masses of fungi in pus and tissu'.es led him to name the or ganism Actinomyces (the ray fungus). The disease" was first recognized in humans by Israeli, and Ponfick shortly after pointed oUt the similarity of the disease described by Bollin- RI 82 ACTA MEDICA PHILIPPINA gcr in cattle to the infection which Israel had observed in man. -

New Medium for Isolation of Actinomyces Viscosus and Actinomyces Naeslundii from Dental Plaque

LOESCHE Department ofMicrobiology, School ofMedicine, and Department of Oral Biology, School of Dentistry, University ofMichigan, Ann Arbor, Michigan 48109 Received for publication 25 November 1977 Metronidazole (10ltg/ml) and cadmium sulfate (20 ,ug/ml) were added to a gelatin-based medium to select for microaerophilic Actinomyces species from dental plaque samples. The new medium (GMC), when incubated anaerobically, allowed 98% recovery of seven pure cultures of Actinomyces viscosus and 73% recovery of eight pure cultures ofActinomyces naeslundii, while suppressing 76% of the total count of other orgnisms in dental plaque samples. In 203 plaque samples, recoveries of A. viscosus and A. naeslundii on GMC and another selective medium for oral Actinomyces (CNAC-20) were compared. Recovery of A. viscosus was comparable on the two media. Recovery of A. naeslundii was significantly higher on GMC than CNAC-20 (P < 0.001), and GMC allowed a more characteristic cell morphology of both organisms. GMC medium appears to be useful for the isolation and presumptive identification of A. viscosus and A. naeslundii from dental plaque.

Review on Actinomycosis in Cattle
Journal of Biology, Agriculture and Healthcare www.iiste.org ISSN 2224-3208 (Paper) ISSN 2225-093X (Online) Vol.8, No.13, 2018 Review on Actinomycosis in Cattle Ufaysa Gensa Jimma University College of Agriculture and Veterinary Medicine, School of Veterinary Medicine. P.O. box 307, Jimma, Oromia, Ethiopia SUMMARY Actinomycosis (lumpy jaw) in cattle is a chronic infectious disease characterized by suppurative granulation of the skull, particularly the mandible and maxilla. A bovis are the etiologic agent of lumpy jaw in cattle. It has also been isolated from nodular abscesses in the lungs of cattle and infrequently from infections in sheep, pigs, dogs, and other mammals. ). Although actinomycosis occurs only sporadically, it is of importance because of its widespread occurrence and poor response to treatment. It is recorded from most countries of the world. Predisposition to disease seems to occur through direct extension of the infection from the gums, apparently following injury or as a complication of periodontitis of other causes. ). In the jawbones a rarefying osteomyelitis is produced. Actinomycosis lesion in the cows appeared as hard and immobile swellings in the mandibles. The disease is sporadic but common in cattle. Occasional cases occur in pigs and horses and rarely in goats. Rarefaction of the bone and the presence of loculi and sinuses containing thin, whey-like pus with small, gritty granules are usual. Treatment is with surgical debridement and antibacterial therapy, particularly iodides as used in case of actinobacillosis. For control, isolation or disposal of animals with discharging lesions is important, although the disease does not spread readily unless predisposing environmental factors cause a high incidence of oral lacerations. -
