Acdb. Decarvalho et al., ENTEROTOXIN PRODUCTION IN STRAINS OF CAMPYLOBACTER-JEJUNI, ISOLATED FROM SWINE DIARRHEA, Revista de Microbiologia, 24(2), 1993, pp. 78-83
One hundred and twenty-six strains of Campylobacter jejuni isolated fr
om swine with diarrhea were examined for the production of enteroxin,
by culture filtrate inoculation into ileal loops in several animal spe
cies. Four (3,1 %) of the strains tested produced fluid in ligated ile
al loop of albino rabbit, 19 (15 %) in rat and 14(11, 1 %) in swine. B
y the test of intragastric inoculation in suckling mouse, none of the
strains revealed capacity to produce enterotoxin, although two strains
were considered suspicious. Twelve (54,5 %) of the strains that induc
ed ileal fluid in rat and swine produced cytotoxic effect in monkey ki
dney cells (Vero), affecting up to 60 % of the monolayer. However, no
alteration was observed in hamster kidney cells (BHK).
