title: Altered adult worm location in young male jirds infected with Brugia pahangi.
abstract: Male jirds (Meriones unguiculatus) were inoculated subcutaneously with 100 Brugia pahangi L3 each at 2, 6, 10, and 15 wk of age to compare their susceptibility and pathologic reactivity to infection. Adult worm recoveries (mean +/- SD) ranged from 24.1 +/- 15.1 to 36.4 +/- 13.9 at 60 days postinfection. No significant difference in susceptibility was measured among the 4 age groups. Jirds infected at 2 wk of age had significantly fewer (alpha less than or equal to 0.025) testicular and intralymphatic worms than all other age groups. Numbers of intralymphatic thrombi were significantly lower (alpha less than or equal to 0.01) in jirds infected at 2 wk of age. Lymphatic lesion severity, expressed as the number of intralymphatic thrombi per intralymphatic worm, was similar between age groups. These data indicate no differences in susceptibility or lymphatic lesion formation following B. pahangi infection in 2-wk-old male jirds, despite altered adult worm location.
