A centrifugation method for recovering tissue larvae is described and is proven to be superior to both Baerman and tissue digest methods for recovering larvae of Ascaris suum from the liver and lungs of infected C57BL/6 mice. Using the spin method for harvesting larvae, C57BL/6 mice were evaluated for their suitability in studies on specific host immunity(More)
The role of eosinophils in ocular ascarid infection is studied in an animal model. Primary intravitreal infection of guinea-pig eyes with ascarid (Toxocara canis, Ascaris suum) second-stage (L2) larvae resulted in an anterior chamber exudate containing 98% or more eosinophils. Anterior chamber aspirates were cultured in RPMI media 1640 with T. canis or A.(More)
Angiostrongylus cantonensis-infected rats were examined for the presence of antigen sensitive lymphocytes, as assessed by the in vitro uptake of tritiated thymidine by cells of various lymphoid organs (cervical, mediastinal and mesenteric lymph nodes, spleen and periphereal blood), following stimulation by adult worm antigen. The lymphoid cell response of(More)
Syngeneic Strain 2 guinea-pigs which received seven s.c. injections of infective eggs of Ascaris suum were shown to harbour less larvae in their lungs than control animals after mesenteric vein challenge with 10,000 infective larvae of A. suum. Serum and cell preparations harvested from these animals were able to transfer protective immunity to normal(More)
Mastomys natalensis, matched according to age and microfilaremia, were divided into Experimental and Control groups. The former were given diethylcarbamazine (Caricide, 500 mg/kg) per os. Microfilariae counts were made at 15, 30, 60, and 120 min and at 1, 5, and 12 days. This protocol was performed on rats with: old infections (patent for 7 mo), new(More)
