Answer to the Parasite Case of the Week 717: Brugia malayi
This case was a little bit tricky in that the tail didn't show a clear terminal and subterminal nucleus as expected for B. malayi. However, the tail nuclei were separated, there is a long head space, and the sheath stained deep pink with Giemsa (the latter being a 'soft' feature).
To confirm the findings, many of you rightly noted that you would try to get the patient's travel history and also look for other microfilariae in this specimen. B. malayi is restricted to Asia and SE Asia and is a cause of lymphatic filariasis.
Thanks again to Florida Fan for donating this case!
