Of the 122 human oral bacterial strains tested from 11 genera, only streptococci and a few actinomyces exhibited coaggregation among the strains within their respective genera. Eight of the ten streptococci showed multiple intrageneric coaggregations, all of which were inhibited by galactosides. The widespread intrageneric coaggregation among the streptococci and the less extensive coaggregatio...
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.
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...
Actinomyces radingae is a rare isolate in clinical specimens. We describe a case of a postmenopausal woman presenting with a breast abscess caused by A. radingae. To our knowledge, this is the second description of a case of a breast infection due to this pathogen. J Microbiol Infect Dis 2016;6(2): 84-86
present paper reports a case of breast actinomycosis due to actinomyces israelii in a 31-year-ol female nurse from shahrekord, in iran. diagnosis was based on the observation of short and very fine gram-positive filaments in direct examination of aspirates from fistulas, as well as isolation of organism in sodium thioglycolate and brain heart infusion blood agar (bhib) culture media, under anae...
Craniofacial Actinomyces osteomyelitis progression is rare, as patients are soon treated. A 56-year-old male smoker presented with sinusitis and was managed medically. This patient failed to follow up and presented 1 year later with erosive bony disease. He was managed medically and surgically; however, his disease evolved to include his midface, skull base, and cranium. He underwent staged deb...
This study investigated the presence of the black-pigmented bacteria Prevotella nigrescens and Prevotella intermedia, the non-black-pigmented bacteria Actinomyces spp and particularly the cariogenic pathogen Streptococcus mutans in the dental biofilms of patients with or without black extrinsic tooth stains, using the multiplex polymerase chain reaction (PCR) technique. Analysis of the dental b...
