✦ Synopsis
In quantitatively infected Meriones unguiculatus autopsied during prepatency, the embryonic development of fertilized eggs in the uteri of female Dipetalonema viteae commenced 29-32 days p.i., and approximately 20 days later the first microfilariae were released. In host animals examined at the onset of patency 45-59 days p.i. the average adult recovery rate was 31%. The worms were localized in the subcutaneous tissue (65.3%), fasciae of muscles (26.9%) and body cavities (7.8%). Female worms from the peritoneal and pleural cavities were significantly longer (44.3 +/- 10.4 mm) than those from the other habitats (33.7 +/- 5.5 mm). Female worms 14-20 weeks p.i. contained a total of 172,700 +/- 62,400 intrauterine stages, 21% of them pathologically altered. Based on these parameters, the expected in vivo fecundity of a female worm was calculated as about 7000 microfilariae per day.
