The purpose of this study was to investigate the effect of streptomycin sulphate in water solutions on the nematode life span. In this experiment streptomycin sulphate was used in following dilutions: 1.0 and 0.1 mg/ml. Three adult animals (3 - 5 days old) were kept in microtitre wells containing 0.5 ml of liquid medium (with E. coli and without streptomycin sulphate) 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, beginning from 3th 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 (mg/ml)


Longevity (days)

















Conclusion: If streptomycin sulphate solution was applied to C. elegans, it was able to increase not significantly (P>0.05) their mean longevity in comparison with control to 6.6 and 15.7 percent, respectively.
