virulence of tubercle bacilli isolated from patients with tuberculosis in bangalore, india. | this is a study of the virulence of cultures of mycobacterium tuberculosis isolated from pulmonary and extrapulmonary forms of tuberculosis in patients living in or near bangalore, india. the findings are as follows: 1. the percentage of cultures recovered from cases of pulmonary tuberculosis in bangalore classified as being of low, moderate, and high virulence, was the same as that reported by mitchison et al., in 1960 for isolates obtained from patients in madras, india. 2. the distribution of ... | 1986 | 3116728 |
inhibition of virulent mycobacterium tuberculosis by murine peritoneal macrophages and human alveolar lavage cells: the effects of lymphokines and recombinant gamma interferon. | both murine peritoneal macrophages and human alveolar lavage cells inhibited growth of m. tuberculosis in a medium containing 10% foetal calf serum. however, whereas addition of recombinant gamma interferon or crude lymphokine reproducibly activated further strong anti-mycobacterial mechanisms in the murine cells, these stimuli had weak and variable effects on human alveolar cells. | 1986 | 3116729 |
national survey of tuberculosis notifications in england and wales in 1983: characteristics of disease. report from the medical research council tuberculosis and chest diseases unit. | the number of newly notified, previously untreated patients in a survey of notifications of tuberculosis in england and wales conducted by the mrc in 1983 was 26% lower than in the previous mrc survey in 1978/79. in both surveys the great majority of patients were of white (about half) or indian subcontinent (indian, pakistani or bangladeshi) ethnic origin (just over a third). the notification rates in the indian subcontinent (isc) ethnic groups were much higher than for the white group and were ... | 1987 | 3116730 |
virulence for guinea pigs of tubercle bacilli isolated from the sputum of participants in the bcg trial, chingleput district, south india. | this study, conducted in madras, india and in madison, wisconsin, usa, was concerned with the virulence of isolates of mycobacterium tuberculosis obtained from the sputum of individuals living in the chingleput district of south india. the following results were obtained. 1. the findings of mitchison with respect to the predominance of low virulence for guinea pigs among isolates from persons living madras, were confirmed on isolates from the sputum of residents of the chingleput district. 2. a ... | 1987 | 3116731 |
the inoculation of tissue specimens into guinea-pigs in suspected cases of mycobacterial infection--does it aid diagnosis and treatment? | the record of guinea-pig inoculations carried out at the london hospital during a 5-year period was examined. a total of 677 specimens were inoculated into guinea-pigs: 34 were positive on culture and guinea-pig post-mortem and 22 were positive on culture alone. only five were positive on guinea-pig post-mortem when culture was negative and in only three of these five cases were mycobacteria isolated from the guinea-pig tissues. all three cases had been diagnosed effectively on histological grou ... | 1987 | 3116732 |
in vitro properties of rifapentine (mdl473) relevant to its use in intermittent chemotherapy of tuberculosis. | in a comparison of in vitro properties of rifapentine (rif) and rifampicin (rmp), the minimal inhibitory concentration of rif against mycobacterium tuberculosis in tween-albumin liquid medium was usually 0.02 micrograms/ml, 2-3 times lower than for rmp; the bactericidal activity against a log phase culture was slightly less than that of rmp and the recovery after pulsed exposures to 1 microgram/ml of rif or rmp lasting 6, 24 and 96 h was identical for the two rifamycins. these findings are used ... | 1987 | 3116733 |
in vitro susceptibility of mycobacterium tuberculosis to a new macrolide antibiotic: ru-28965. | the in vitro susceptibility of mycobacterium tuberculosis to a new macrolide antibiotic ru-28965, alone and in combination with rifampicin or isoniazid, was studied by the agar dilution method. at a concentration of 4 mg/l, or lower, of ru-28965, 90% of the strains were inhibited. a synergistic effect with both rifampicin and with isoniazid was demonstrated. | 1987 | 3116734 |
is the tuberculosis screening program of hospital employees still required? | the american thoracic society and the centers for disease control recommend that each hospital has a tuberculosis screening program. as the incidence of active tuberculosis in the united states has been decreasing during the last 30 yr, the necessity for continuing this screening program may be questioned. this prospective study evaluates whether screening hospital employees is still useful. in the state of washington from january 1, 1982, through december 31, 1984, tuberculosis was diagnosed in ... | 1987 | 3116895 |
