actinomyces viscosus isolation from skin lesions in iran

چکیده
this paper presents a case-report of cutaneous actinomycosis due to actinomyces viscosus in a 22 year old man, hospital staff from tehran with multiple fistulous tracts in his right hand and a history of skin injury due to thorn of plant. diagnosis was based on the observation of gram positive coccoid, diphtheroid and long branching filaments in direct examination of pus from fistulous tracts and isolation of microorganism in thioglycolate and brain heart infusion (bhi) agar media in anaerobic conditions and some physiologic tests. treatment of lesion was down with doxycyclin and penicillin 3 months and healing was acquired.

Isolation of Actinomyces viscosus from two patients with clinical infections.
The isolation of Actinomyces viscosus from two patients is described. One was a case of multiple myeloma, the organism being found on blood culture; the other was a patient with a submandibular abscess. These are believed to be the first such isolations of A. viscosus in this country.
متن کاملIsolation of a neuraminidase gene from Actinomyces viscosus T14V.
A genomic library of Actinomyces viscosus T14V DNA in lambda gt11 was screened for expression of neuraminidase activities. Four recombinant clones were detected that gave blue fluorescence upon incubation with a fluorogenic substrate, 2'-(4-methylumbelliferyl)-alpha-D-N-acetylneuraminic acid. Of these, two were identical, and all of the neuraminidase-positive clones shared a common 3.4-kbp DNA ...
متن کاملIdentification of Actinomyces viscosus from canine infections.
Actinomyces viscosus is a gram-positive, non-acid-fact, facultative, catalase-positive, filamentous, or diphtheroidal microorganism. It was isolated from six canine infections during a period of 1.5 years. The organism was cultured from exudate and flaky granules aspirated from infectious granulomas and empyemas. All cultures grew well aerobically and anaerobically with the addition of 10% carb...
متن کاملMannose-contaminating agglutinin for Actinomyces viscosus and Actinomyces naeslundii.
Rapid agglutination of Actinomyces viscosus and Actinomyces naeslundii cells by D-mannose solutions was observed during studies of their attachment to mammalian cells in vitro. The specificity of the agglutination reaction was studied by slide agglutination tests and by measuring the rate of decrease in optical density of bacterial phosphate buffer suspensions caused by the setting of bacterial...
متن کاملSurface fibrils (fimbriae) of Actinomyces viscosus T14V.
Surface antigens of Actinomyces viscosus T14V were released from cell walls by digestion with lysozyme. These were separated by ion-exchange and gel filtration chromatography into fractions rich in carbohydrate or protein. The former contained a polysaccharide high in 6-deoxytalose, along with a peptide fragment from the cell wall. In the protein-rich fractions, material of high molecular weigh...
متن کاملCell-associated levan of Actinomyces viscosus.
Actinomyces viscosus ATCC 15987 was examined for the presence of cell-associated levan by absorption of myeloma proteins with antilevan activity and direct immunofluorescence. Levan was not detectable on the surface of glucose-grown A. viscosus, but after a brief incubation of these cells with 5% sucrose, they were encapsulated with tenaciously adhering levan. The levan layer constituted betwee...
