A species of Brugia, probably B. ceylonensis, was recovered from the conjunctiva of a patient in Sri Lanka for the first time. This infection represents only the second record of Brugia in the human conjunctiva, and is clearly zoonotic, acquired from a dog. Brugia ceylonensis has a distinct head bulb like that of Wuchereria bancrofti and B. malayi. However, the parasite recovered was not W. bancrofti, as specific IFAT and DNA probes gave negative results, and B. malayi is believed to have been eradicated from Sri Lanka several years ago. The presence of a distinct head bulb excludes the possibility that the parasite was B. buckleyi.
