We conducted a population-based study of tuberculosis (TB) cases in Dourados, Brazil, to assess the relationship between incarceration and TB in the general population.
In a 7-year population-based study of tuberculosis in Karonga District, Malawi, clusters were defined by using IS 6110 restriction fragment length polymorphism, excluding patterns with <5 bands.
The protein sequences of M. vanbaalenii share important sequence motifs with M. tuberculosis useful for drug efflux mechanism based study across species.
It is also the first systematic community based study conducted to assess strain diversity, associated HIV sero-status and anti-tuberculosis drug resistance of M. tuberculosis complex in a peri-urban population of Uganda.
In contrast, community based studies will likely provide a lower estimate of the percentage of total TB patients who are infected with an MDR or XDR strain of M. tuberculosis.
The tuberculosis status of the enrolled patients was based on results of tuberculosis testing at current admission.
Recent findings from studies of tuberculosis infection and of patients with Mendelian predisposition to severe tuberculosis have started to reveal human loci influencing tuberculosis outcomes.
This circumstance underscores the relevance of population studies of tuberculosis for transmission dynamics control.
Support for the former hypothesis is based on studies of patients with ocular inflammation in which M. tuberculosis was identified in ocular specimens through histopathology or nucleic acid amplification [12 14].
So far however, changes in the population structure of M. tuberculosis are largely based on studies of currently abundant strains.
The largest study of bovine tuberculosis (TB) in badgers was the randomised badger culling trial, RBCT, which reported in 2007.
