Abstract:
We investigated levels of equipment sharing in injecting drug users in Sydney, Australia, in two consecutive samples recruited in a non-treatment setting using similar methodology in 1989 (n = 1,245) and 1990 (n = 550). Comparison between the two waves of the study indicated that there were consistent and major reductions in percentage of time used equipment was re-used, and number of people from whom used equipment had been accepted. There was a corresponding significant and major increase in use of sterile injection equipment, obtained more frequently in the second sample from needle and syringe exchanges. The proportion of respondents reporting they had never shared equipment rose significantly. These data suggest that there is a continuing increase in the adoption of safer injecting practices and utilisation of needle and syringe exchanges over time in response to the threat of HIV transmission in injecting drug users.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
