Abstract:
The incidence of the acquired immunodeficiency syndrome (AIDS) in Malawi is one of the highest in Central Africa. Since tuberculosis is an important initial manifestations of the disease, consecutive patients admitted to the tuberculosis (TB) wards of Zomba General Hospital, Malawi, were asked for permission to undergo a human immunodeficiency virus (HIV)-antibodies test. In addition, two other studies were done: from September 1986 all medical in-patients, clinically suspected for immune deficiency and from April 1988 all blood donors were tested for HIV seropositivity. Seventy-five percent of the TB patients volunteered; 32 out of 125 (26%) were seropositive. In the high-risk age groups (20-40 years) this percentage rose to 32. Among the medical in-patients suspected of immune deficiency the seropositivity rose sharply from April 1987 to October 1988. Among the blood donors tested, 20% were seropositive.

Pulmonary Tuberculosis I
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.
