We examined the characteristics of Peptostreptococcus species in infectious skin diseases. P. magnus was the species identified most frequently, followed by P. asaccharolyticus. Peptostreptococcus species were mainly isolated from infected atheroma and secondary infections due to ulcers; their resistance to five antimicrobial agents was generally low. The(More)
We examined predominant Staphylococcus aureus isolated from lesions of various skin diseases, and during the past 3 years, 113 methicillin-sensitive and 31 methicillin-resistant S. aureus have been isolated. The predominant species isolated from almost all of the primary bacteriological cultures was S. aureus. The skin diseases from which cultures were most(More)
Shiunko is a typical Kampo drug made from herbal extracts and used to treat a range of conditions including atopic dermatitis. Shiunko, white petrolatum and 3.5% salt water were applied to the skin of atopic dermatitis patients, and their clinical effectiveness, and the changes in bacterial species and cell numbers on the skin were studied. Staphylococcus(More)
We studied the effects of minocycline on Propionibacterium granulosum. P. granulosum lipase activity was detected from acne lesions. Production of propionic and butyric acids by P. granulosum was well suppressed by all tested media with added minocycline; the higher the concentration of minocycline in the medium, the less of these acids was produced. It(More)
We studied the lipase activities of Propionibacterium granulosum, P. acnes and the suppression of these activities by Jumi-haidoku-to (JHT). Lipase activity of P. acnes biotype III (BIII) was strongest, while that of P. granulosum was faintly expressed. Compared with the control medium, the production of propionic and butyric acids was suppressed by all the(More)
From January 1995 to June 2000, 19 Pseudomonas aeruginosa were detected in 19 cases of infectious skin diseases. Coagulase-negative staphylococci coexisted with P. aeruginosa in 10 cases and P. aeruginosa was also often associated with Enterococcus sp., Staphylococcus aureus, Streptococcus sp. or other species. Twelve cases carried P. aeruginosa more(More)
We examined the relationship between Propionibacterium acnes biotypes and Jumi-haidoku-to (JHT). In all the P. acnes strains tested, the production of propionic acid (PA) and butyric acid (BA) was suppressed in a medium containing 1 mg/ml JHT compared with the control medium without JHT. There were no significant differences in the rates of decreased PA and(More)
The distribution and antimicrobial susceptibility of coagulase-negative staphylococci from skin lesions were investigated. Staphylococcus epidermidis was found on all areas of the body, whereas S. capitis, S. haemolyticus and S. hominis were mainly found on the face/head or arm/leg. The distribution of coagulase-negative staphylococci in skin lesions and at(More)
During the period from January of 1995 to June of 1998, 27 beta-hemolytic streptococci were isolated from 25 cases of infectious skin diseases including secondary infections, impetigo, phlegmone, and paronychia. The rate of beta-hemolytic streptococci among all kinds of the isolates was found to be similar during those 4 years, ranging from 3.5% to 5.6%.(More)
