Article: Spoligotyping profile change caused by deletion of a direct variable repeat in a Mycobacterium tuberculosis isogenic laboratory strain.
[show abstract] [hide abstract]
ABSTRACT: Spoligotyping is a major tool for molecular typing of Mycobacterium tuberculosis complex organisms. For epidemiological purposes, strains are considered clonal only when their spoligotyping patterns are identical. We report a change in the spoligotyping profiles of truly isogenic strains (a clinical isolate and a subculture derived in the laboratory) caused by deletion of a direct variable repeat. Without the information about the relationship between them, a link between these strains would have gone unnoticed. Evolutionary events should be taken into account in the interpretation of spoligotyping results and in the design of databases.Journal of Clinical Microbiology 12/2004; 42(11):5388-91. · 4.15 Impact Factor -
Article: Bovine tuberculosis (Mycobacterium bovis) in wildlife in Spain.
[show abstract] [hide abstract]
ABSTRACT: Mycobacterium bovis infection in wildlife and feral species is a potential source of infection for livestock and a threat to protected and endangered species. The aim of this study was to identify Spanish wild animal species infected with M. bovis through bacteriological culture and spacer oligonucleotide typing (spoligotyping) of isolates for epidemiological purposes. This study included samples from red deer (Cervus elaphus), fallow deer (Dama dama), wild boar (Sus scrofa), Iberian lynx (Lynx pardina), hare (Lepus europaeus), and cattle (Bos taurus). They were collected in several geographical areas that were selected for their unique ecological value and/or known relationships between wildlife and livestock. In the areas included in this survey, M. bovis strains with the same spoligotyping pattern were found infecting several wild species and livestock, which indicates an epidemiological link. A locally predominant spoligotype was found in these areas. Better understanding of the transmission and distribution of disease in these populations will permit more precise targeting of control measures.Journal of Clinical Microbiology 07/2004; 42(6):2602-8. · 4.15 Impact Factor
