| a demographic study of disease due to mycobacterium kansasii or m intracellulare-avium in texas. | the number of patients reported th have disease due to mycobacterium kansasii or m intracellulare-avium has increased in texas from january 1967 to december 1976, in contrast to a decrease in tuberculosis. presented is an analysis of 1,409 patients infected with m kansasii and 706 patients infected with m intracellulare-avium. the former group clustered in urban areas with more than twice the incidence compared to nonurban areas (p less than 0.001). the latter group was more diffusely distribute ... | 1979 | 421546 |

| pulmonary and disseminated infection due to mycobacterium kansasii: a decade of experience. | fifty-five patients with mycobacterium kansasii isolates (47 pulmonary and eight disseminated) were identified at a large texas hospital from 1975 to 1985. the mean age of patients was 60 years, and there was a slight male predominance. isolation of m. kansasii usually represented disease. the great majority of patients with pulmonary infection due to m. kansasii had underlying pulmonary diseases, and 70% had nonpulmonary predisposing factors. m. kansasii pulmonary disease clinically and radiogr ... | 1990 | 2237115 |

| improved technique for isolation of mycobacterium kansasii from water. | a new concentration procedure, together with a new isolation medium, resulted in a 10- to 100-fold increase in the possibility of identifying mycobacterium kansasii from water samples in comparison to a previously used procedure. in a survey which included both potable and natural water samples from many sites within the state of texas, nine isolations of high-catalase strains of m. kansasii were obtained from 232 water samples tested. acid-fast smear results were compared with mycobacterial iso ... | 1981 | 7016916 |
| high-catalase strains of mycobacterium kansasii isolated from water in texas. | isolation techniques with membrane-filtered potable water samples resulted in the isolation of potentially pathogenic high-catalase strains of mycobacterium kansasii from 8 of 19 representative outlets in a small central texas town. mycobacterium gordonae was isolated from all samples, and mycobacterium fortuitum was isolated from two samples. data on chlorine levels are presented along with a possible explanation for the unusually high numbers of mycobacteria in these potable water samples. fin ... | 1980 | 7381016 |
| rifampin-resistant mycobacterium kansasii. | we identified 36 rifampin-resistant mycobacterium kansasii isolates, including 17 (4%) of 464 isolates recovered in texas between 1989 and 1992. of 29 patients infected with rifampin-resistant m. kansasii whose history of medication was known, 90% had previously received rifampin, and 58% of these patients had been treated with one or two effective drugs. thirty-two percent of rifampin-resistant isolates recovered since 1989 were from patients who were seropositive for human immunodeficiency vir ... | 1994 | 8075262 |
| molecular analysis of mycobacterium kansasii isolates from the united states. | we studied the population genetics of mycobacterium kansasii isolates from the united states by pcr restriction enzyme analysis (pra) of the 441-bp telenti fragment of the hsp-65 gene and pulsed-field gel electrophoresis (pfge) of genomic dna with the restriction endonucleases asei, drai, and xbai, and we compared the patterns to those previously reported from france and japan. by pra, 78 of 81 clinical isolates (96%) from the united states belonged to subspecies i. with pfge, 28 asei patterns, ... | 2004 | 14715741 |
