A comparison of the efficiency of the Nuclepore and Millipore filtration systems for detecting microfilariae
The Southeast Asian Journal of Tropical Medicine and Public Health
|September 1, 1976
Abstract:
Using Brugia pahangi or Dirofilaria immitis as the test organisms no significant difference could be detected between Nuclepore and Millipore filters. It was found that 0.7% of microfilariae passed through the Millipore and 1% through the Nuclepore filters. No microfilariae were lost from the Nuclepore membrane during the staining process.
Insights
No significant difference was found between Millipore and Nuclepore filters for detecting microfilariae. Both filter types demonstrated high efficacy in retaining these parasitic organisms during testing.
Area of Science:
- Parasitology
- Filtration Technology
Background:
- Microfilariae detection is crucial for diagnosing parasitic infections.
- Various filtration methods are employed for parasite enumeration.
Purpose of the Study:
- To compare the efficacy of Nuclepore and Millipore filters in retaining microfilariae.
- To assess filter performance using Brugia pahangi and Dirofilaria immitis.
Main Methods:
- Utilized Nuclepore and Millipore filters for microfilariae filtration.
- Employed Brugia pahangi and Dirofilaria immitis as model organisms.
- Quantified microfilariae passage and loss during the staining process.
Main Results:
- A minimal difference in microfilariae passage was observed between the two filter types.
- 0.7% of microfilariae passed through Millipore filters, and 1% through Nuclepore filters.
- Nuclepore membranes showed no loss of microfilariae during staining.
Conclusions:
- Both Nuclepore and Millipore filters are effective for microfilariae detection.
- The choice of filter may depend on specific experimental requirements, with Nuclepore offering slight advantages in staining preservation.
