摘要：The Australian Mycobacterium Reference Laboratory Network collected and analysed laboratory data on newdiagnoses of infection with Mycobacterium tuberculosis complex during 1996. A total of 750 cases were identified,representing an annual incidence of 4.1 cases of laboratory confirmed tuberculosis per 100,000 popu lation. Theincidence rate varied between States, reflecting differences in the distribution of persons belongi ng to 'high-risk'categories for tuberculosis. Incidence statistics were almost identical to those recorded by the N etwork in 1994 and1995. The male:female ratio remained at around 1.2:1. As was the case in 1995, the median age gro up for males was 45-49 years and for females 35-39 years. The frequency of positive microscopy in pulmonary samples was stable ataround 55%. Lymphatic disease accounted for 19% of the total cases in 1996 compared with 15% in the previousyear, confirming that lymphadenitis is becoming more common in females with tuberculosis in Austral ia. Approximately 11% of isolates had in vitro resistance to at least one of the four standard anti-tuberculosis drugs, anincrease from 8% in 1994-95. Fifteen isolates were multi-drug resistant, compared with a total of only 38 during the previous seven years. Thus, the 1996 data points to an increasing frequency of multi-drug resistan t strains amongisolates from Australian patients with tuberculosis
