The purpose of this study was to investigate the effect of different concentrations of streptomycin sulphate in presence of ascorbic acid (concentration 1:104) in water solutions on the nematode life span in reproductive period. In this experiment streptomycin sulphate was used in following dilutions: 1:101, 1:102, 1:103, 1:104, 1:105, 1:106 and 1:107. Three adult animals (3 - 5 days old) were kept in microtitre wells containing 0.5 ml of liquid medium (with E. coli and without ascorbic acid) during 4 hours, then they were discarded and newborn larvae were transferred in next wells (without streptomycin sulphate in medium) every day (one worm in one well) beginning from third day. Then, from 3th to 10th day, these worms were transferred every day in next wells containing medium with streptomycin sulphate in any concentration. This investigation was carried out in temperature +21°C and in the darkness.
The obtained results are presented in the following table.
| Concentration of streptomycin sulphate | n | Longevity (days) | |
| Mean±S.E. | Maximal | ||
| Control | 12 | 12.8±1.1 | 18 |
| 1:103 | 12 | 13.7±0.7 | 21 |
| 1:104 | 12 | 14.0±0.6 | 23 |
Conclusion: If streptomycin sulphate solution in presence of ascorbic acid was applied to C. elegans, it was not able to increase significantly (P>0.05) their mean longevity in comparison with control.
