[Prevalence of antibodies against HIV in drug addicts and convicts]
Abstract:
The presence of anti-HIV (human immunodeficiency virus) antibodies was determined in 325 subjects. The samples were taken from 138 convicts from Carabanchel and Ocaña I jail, 162 parenteral drug addicts (PDA) from a center for rehabilitation of drug addicts (CR), and from 14 family members and 11 stable couples of these PDAs. There was a global seroprevalence of 61.23%, 56.9% in Carabanchel, 68.7% in Ocaña I and 68.5% in the CR. When the results from the jailed convicts were analyzed according to risk factors, it was discovered that drug addiction was the most relevant since there was only a 29.4% of seropositivity in non PDAs with a statistically significant difference (p less than 0.01). This value was also higher than the seroprevalence found in the CR with a statistically significant difference (p less than 0.01). None of the family members of the CR were HIV-positive. Two stable couples were positive in this sexual contact group. This article makes clear the important role of drug addiction in the dispersion of HIV infection in our midst.

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.
