(1) The results showed that the P. ovale antigen was distinguished by a marked activity with those sera that had reacted only with P. fieldi in the screening test.
(2) Out of 880 sera which were examined for antibodies to plasmodia 69 (7.8%) reacted only with P. falciparum antigen, 371(42.2%) reacted only with P. fieldi antigen, and 440 (50%) responded to both antigens.
(3) In the venom of P. p. fieldi, which has no hemorrhagin or L-amino acid oxidase, the high molecular weight fraction of proteins is practically missing.
(4) Serum samples were tested using Plasmodium falciparum, P. vivax, P. malariae and P. fieldi antigens.
(5) The very high lethal potency of the neurotoxic complex (Cb) from the venom of Pseudocerastes fieldi following direct administration into the lateral ventricle of the brain, as compared with potency following i.v.
(6) 57.8%, of the sera were positive) than P. fieldi (811, i.e.
(7) Macaca fascicularis monkeys from Mauritius were shown to be susceptible via sporozoite inoculation to 7 species of Plasmodium (P. fragile, P. coatneyi, P. gonderi, P. inui, P. cynomolgi, P. knowlesi, and P. fieldi), indigenous to macaques in southeastern Asia.
(8) Gel-isoelectric focusing of Pseudocerastes persicus fieldi venom shows a simple pattern with very few protein bands, while the venom of P. p. persicus reveals close to 30 protein bands.
(9) The neurotoxic complex (Cb) from the venom of Pseudocerastes fieldi consists of an acidic non-toxic subunit (CbI) and a basic toxic one (CbII).
