M. Hintz et al., JUVENILE FEMALE LITOMOSOIDES SIGMODONTIS PRODUCE AN EXCRETORY SECRETORY ANTIGEN (JUV-P120) HIGHLY MODIFIED WITH DIMETHYLAMINOETHANOL/, Parasitology, 117, 1998, pp. 265-271
A 120 kDa antigen produced by juvenile female Litomosoides sigmodontis
(Juv-p120) was isolated and purified. The amino acid composition of t
he molecule was determined. Juv-p120 was shown to be highly modified w
ith N,N-dimethylaminoethanol (28.4 mol %). Treatment of Juv-p120 with
potassium hydroxide (beta-elimination) or with sodium m-periodate lead
s to the destruction of epitopes recognized by antibodies immune affin
ity-purified with isolated Juv-p120. Juvenile L. sigmodontis were show
n to release Juv-p120 into the pleural cavity of infected Mastomys cou
cha before the onset of patency.
