Genetic diversity and potential routes of transmission of Mycobacterium bovis in Mozambique

Abstract: Bovine tuberculosis is a zoonotic disease with largely unknown impact in Africa, with risk factors such as HIV and direct contact with animals or consumption of Mycobacterium bovis infected animal products. In order to understand and quantify this risk and design intervention strategies, good epidemiological studies are needed. Such studies can include molecular typing of M. bovis isolates. The aim of this study was to apply these tools to provide novel information concerning the distribution of bovine tubercu… Show more

“…Genetic variability displayed in the VNTR profiles in cattle in our study area (15 VNTR profiles) either infers several local and stable sources of infection or the long-term persistence and evolution of one or more precursor strains. The spoligotypes SB0130 and SB0140 strains are linked to the European 1 (Eu1) clonal complex and where possibly introduced into the country during cattle imports from the UK during colonial times [21,33]. Thus, the numerous VNTR types might be related to the earlier introduction of bTB into this community; as it has been proposed that persistence of an infection presents more opportunities for genetic evolution [21].…”

“…O MIRU-VNTR é um método de genotipagem baseado na amplificação por PCR que utiliza iniciadores específicos das regiões flanqueadoras de múltiplos loci para a determinação do número de cópias dos MIRU-VNTR pela análise do tamanho dos produtos de amplificação (SUPPLY et al, 2001 MACHADO et al, 2018). Esse conhecimento torna aprofundado sobre epidemiologia molecular, só se torna relevante quando se conhece as particularidades da pecuária de cada região.…”
