Summary of the General Morphologic Characteristics of the Microfilariae:
Filarial Agent | Lenth | Width | Nuclear Column |
Brugia malayi | Large (>200 μm in length) | Large species tend to be as wide as a red blood cell (RBC), about 6-8 μm in diameter
| Compact (dense) |
Headspace | Tail | Sheath on Giemsa |
Long | Terminal and subterminal nuclei, large gaps separate these nuclei | Present: Bright pink |
