HIV-1 infection and HIV-1-induced immune deficiency may play a role in selecting particular Mycobacterium tuberculosis (MTB) strains (i.e. genotypes). We compared 43 MTB isolates obtained from HIV-1-infected patients with 77 MTB isolates obtained from HIV-1-uninfected patients in Burkina Faso, by means of DNA fingerprinting methods (MIRU-VNTR plus spoligotyping). This study suggests a lack of s...
BACKGROUND Tuberculosis remains an endemic public health problem, but the ecology of the TB strains prevalent, and their transmission, can vary by country and by region. We sought to investigate the prevalence of Mycobacterium tuberculosis strains in different regions of Venezuela. A previous study identified the most prevalent strains in Venezuela but did not show geographical distribution nor...
BACKGROUND The occurrence of paratuberculosis in Ugandan cattle has recently been reported but there is no information on the strains of Mycobacterium avium subspecies paratuberculosis (MAP) responsible for the disease. The aim of this study was to isolate and characterise MAP from seropositive cattle and paratuberculosis lesions in tissues obtained from slaughtered cattle in Uganda. RESULTS ...
BACKGROUND Bovine tuberculosis (TB) caused by Mycobacterium bovis is primarily a disease of ruminants, particularly cattle (Bos primigenius) and buffalo (Syncerus caffer), and is endemic in most developing countries. To date, studies done in Uganda have documented the prevalence of M. bovis in cattle, humans and wild life, in addition to non-tuberculous mycobacteria in pigs. Pigs are increasing...
BACKGROUND Tuberculosis (TB) patients with multiple episodes of anti-TB treatment represent an important source of TB transmission, as well as a serious threat to the control of drug resistant TB, due to the high risk of multidrug and extensively drug resistance (MDR/XDR) and elongating infectiousness of this patient group. In this study we analyzed the possible risk of development and transmis...
BACKGROUND Recurrence of tuberculosis after treatment makes management difficult and is a key factor for determining treatment efficacy. Two processes can cause recurrence: relapse of the primary infection or re-infection with an exogenous strain. Although re-infection can and does occur, its importance to tuberculosis epidemiology and its biological basis is still debated. We used whole-genome...
