Parasitological observations on Meriones unguiculatus singly or multiply infected with Brugia pahangi

When jirds were infected with a single inoculum of 25-50 infective larvae of Brugia pahangi an overall mean recovery of adult worms of 44.5% (n = 41) was obtained. There was no difference in recoveries between male and female jirds. If jirds were repeatedly inoculated with larvae into the peritoneal cavity yields were only slightly reduced. Yields were 30.5% for 5 infections (n = 10), 26.7% for 10 infections (n = 8), 34.4% for 15 infections (n = 10) and 28.5% for 20 infections (n = 7). Twice as many worms were recovered from intraperitoneally inoculated jirds than from subcutaneously inoculated jirds.
