The subject of the investigation is a group of 27 strains of Mycobacterium tuberculosis isolated in 2000 from prisoners with the diagnosis of tuberculosis, 19 Czechs and 8 foreigners (mean age 41 and 35 years resp.). The molecular-epidemiological examination of these strains was made using the RFLP fingerprint technique (Restriction Fragment Length Polymorphism) with evidence of the insertive sequence IS6110 and the technique of spoligotyping, based on detection of hybridization of spacer oligonucleotides. DNA fingerprinting revealed a high polymorphism in the number and molecular weight of sequence IS6110 which is common in Czech and other European strains of M. tuberculosis. All strains with the exception of two had mutually different fingerprint profiles. In the two with identical fingerprints probably a duplicit examination of the same material was involved which occurred by mistake during transport or in the laboratory. The fingerprint method thus did not prove interhuman transmission of tuberculosis between the examined prisoners. The technique of spoligotyping revealed the finding of genotype Beijing M. tuberculosis in two sick prisoners, one Algerian and one Albanese, and in one Czech prisoner. This genotype found in a high percentage of patients in southeastern Asia and in migrants from this area was detected for the first time in the Czech Republic. The findings are evidence of a satisfactory standard of the programme of tuberculosis control in the Czech prison system and at the same time draw attention to the potential possibility of the spread of tuberculosis from migrants coming from areas with a high prevalence.
