Chronic infection of cats with Brugia malayi and streptococcus.

An elephantoid condition was seen in the affected limbs of 5 of 6 cats at necropsy 12 to 18 months after initial infection with Brugia malayi. Repeated infection with Brugia and exposure to an opportunistic streptococcus appeared to enhance the production and persistence of edematous and fibrotic tissues surrounding the affected lymphatics.
