16. Computer Analysis of IS6110 RFLP Patterns of Mycobacterium tuberculosis.

Author

Walker, John M., Parish, Tanya, Stoker, Neil G., Heersma, Herre F., Kremer, Kristin, and van Embden, Jan D. A.

Abstract

The discovery of polymorphic, repetitive DNA in the Mycobacterzum tuberculosis complex has led to many methods for differentiating clinical isolates belonging to this spectes of pathogenic bacteria. The most widely used method 1s restriction fragment-length polymorphism (RFLP) analysis of msernon sequence IS6110, based on Southern blotting of PvuII-digested genomrc DNA and hybridization. IS6110 is a mobile genettc element of 1.3 kb that is present in virtually all Ad. tuberculosn strains (1). Because the number of IS6110 copies varies between 1 and 25, and the sites of insertion (IS) in the chromosome differ from strain to strain, an enormous diversity in IS6110 banding patterns is found among clmical isolates of hf. tuberculosis. This diversity is the basis for using IS6110 fingerprinting for epidemiological purposes. Generally, strains from outbreaks, or from patients with a common transmission route, display an identical banding pattern, although in large outbreaks, small variattons in banding patterns may be observed, such as the loss or gam of a single band (1,2,3). Strains with identical IS6120 banding patterns will be referred to as matching or "clustered" strains. Such clustered strains are very likely to be derived from a common ancestor in the recent past (perhaps two to ten years ago). Although the exact pace of the "molecular clock" of IS6210 is not known, strains do not usually change in then fingerprmt pattern during transmission chains lasting l-3 yr (2J-6).

Abstract

ABSTRACTThe present update on the global distribution of Mycobacterium tuberculosiscomplex spoligotypes provides both the octal and binary descriptions of the spoligotypes for M. tuberculosiscomplex, including Mycobacterium bovis, from >90 countries (13,008 patterns grouped into 813 shared types containing 11,708 isolates and 1,300 orphan patterns). A number of potential indices were developed to summarize the information on the biogeographical specificity of a given shared type, as well as its geographical spreading (matching code and spreading index, respectively). To facilitate the analysis of hundreds of spoligotypes each made up of a binary succession of 43 bits of information, a number of major and minor visual rules were also defined. A total of six major rules (A to F) with the precise description of the extra missing spacers (minor rules) were used to define 36 major clades (or families) of M. tuberculosis. Some major clades identified were the East African-Indian (EAI) clade, the Beijing clade, the Haarlem clade, the Latin American and Mediterranean (LAM) clade, the Central Asian (CAS) clade, a European clade of IS6110low banders (X; highly prevalent in the United States and United Kingdom), and a widespread yet poorly defined clade (T). When the visual rules defined above were used for an automated labeling of the 813 shared types to define nine superfamilies of strains (Mycobacterium africanum, Beijing, M. bovis, EAI, CAS, T, Haarlem, X, and LAM), 96.9% of the shared types received a label, showing the potential for automated labeling of M. tuberculosisfamilies in well-defined phylogeographical families. Intercontinental matches of shared types among eight continents and subcontinents (Africa, North America, Central America, South America, Europe, the Middle East and Central Asia, and the Far East) are analyzed and discussed.

19. Genetic Heterogeneity in Mycobacterium tuberculosisIsolates Reflected in IS6110Restriction Fragment Length Polymorphism Patterns as Low-Intensity Bands

Author

Abstract

ABSTRACTMycobacterium tuberculosisisolates with identical IS6110restriction fragment length polymorphism (RFLP) patterns are considered to originate from the same ancestral strain and thus to reflect ongoing transmission. In this study, we investigated 1,277 IS6110RFLP patterns for the presence of multiple low-intensity bands (LIBs), which may indicate infections with multipleM. tuberculosisstrains. We did not find any multiple LIBs, suggesting that multiple infections are rare in the Netherlands. However, we did observe a few LIBs in 94 patterns (7.4%) and examined the nature of this phenomenon. With single-colony cultures it was found that LIBs mostly represent mixed bacterial populations with slightly different RFLP patterns. Mixtures were expressed in RFLP patterns as LIBs when 10 to 30% of the DNA analyzed originated from a bacterial population with another RFLP pattern. Presumably, a part of the LIBs did not represent mixed bacterial populations, as in some clusters all strains exhibited LIBs in their RFLP patterns. The occurrence of LIBs was associated with increased age in patients. This may reflect either a gradual change of the bacterial population in the human body over time or IS6110-mediated genetic adaptation of M. tuberculosisto changes in the environmental conditions during the dormant state or reactivation thereafter.
