| diversity of biosurfactant producing microorganisms isolated from soils contaminated with diesel oil. | biosurfactant production is a desirable property of hydrocarbon-degrading microorganisms (hdm). we characterized biosurfactant producing microbial populations from a long beach soil, california (usa) and a hong kong soil (china), contaminated with diesel oil. a total of 33 hydrocarbon-utilizing microorganisms were isolated from the soils. twelve isolates and three defined consortia were tested for biosurfactant production and emulsification activity. the highest reduction of surface tension was ... | 2005 | 16035236 |
| clinical signs, magnetic resonance imaging features, and outcome after surgical and medical treatment of otogenic intracranial infection in 11 cats and 4 dogs. | brainstem dysfunction resulting from central extension of infection is a life-threatening complication of otitis media/interna (omi) that has been described infrequently in dogs and cats. we review the clinical signs of disease, diagnostic findings, and results of surgical and medical treatments of brainstem disease attributable to otogenic intracranial infection in cats and dogs. eleven cats and 4 dogs were examined because of acute, subacute, or chronic clinical signs of brain disease includin ... | 2006 | 16734103 |
| actinomyces species as a cause of abscesses in nine horses. | the characteristics, history, clinical signs, treatment and outcome of nine horses with abscesses caused by actinomyces species were reviewed. dna sequencing was used to determine the species of one of the isolates. the horses were one to 11 years of age, and the abscesses were most commonly located in the submandibular and retropharyngeal regions. the bacterium was usually cultured as the sole isolate and the horses were most often affected in the autumn. most of the abscesses were treated with ... | 2008 | 18178933 |
| abundant microorganism in soil. | the presence in soil of large numbers of a catalase-negative, microaerophilic, coccoid microorganism was demonstrated. use of media of high nutrient value, without incorporation of inhibitors, and growth in the absence of antagonistic microorganisms were utilized to isolate this organism from soil dilutions greater than those providing growth by other means. the organism described does not grow on soil extract agars and is missed by conventional counting techniques for soil organisms. on the bas ... | 1965 | 14325269 |
