Cytolytic activity and enhancement of lysis by 38 MEEs*
| Type of effusion | ||
|---|---|---|
| Type of lysis | Mucoid (n = 25) | Other (n = 13) |
| Direct | 7 (28%) | 6 (46%) |
| Enhancement | 17 (68%) | 10 (76%) |
| Both | 7 (28%) | 4 (31%) |
| Inhibition | 3 (13%) | 0 |
Mucoid and other types of MEE (mucopurulent, seromucous and serous) were tested for their direct cytolytic activity or an ability to enhance or inhibit lysis of unsensitized guinea pig or chicken erythrocytes induced by NHS (see Fig. 1).
