survey of trichinosis in breeding and cull swine, using an enzyme-linked immunosorbent assay.serum samples obtained from 40,927 swine at various locations in north carolina between aug 1, 1987 and july 31, 1988, were tested for antibodies to trichinella spiralis, using an elisa based on a larval t spiralis excretory-secretory antigen. in the elisa, samples were considered to have positive results if the optical density (od) reading was equal to or 5 times greater than the mean od value of 4 negative-control sera from trichina-free swine. of the 40,927 serum samples tested, 154 (0.38%) w ...19902368950

seroprevalence of toxoplasma gondii and trichinella spiralis in finishing swine raised in different production systems in north carolina, usa.we compared the seroprevalence of both toxoplasma gondii and trichinella spiralis in finishing pigs raised in different production systems in north carolina, usa. farms were either finishing sites using all-in/all-out management of buildings in multiple-site systems (14 farms) or farrow-to-finish systems using continuous-flow management of finishing barns or outdoor accommodation 14 farms). the two groups of herds differed with respect to several management variables. a total of 13 of 2238 sampl ...19989677628
seroprevalence of toxoplasma gondii and trichinella spiralis in north carolina black bears (ursus americanus).serum samples from 143 hunter-killed black bears were collected during the 1996 and 1997 black bear hunting seasons in eastern north carolina. all samples were tested for antibodies to toxoplasma gondii by the modified agglutination test. antibodies to t. gondii were present in 120 of 143 (84%) bears. females had significantly higher titers than males (wilcoxon rank sums test, p = 0.045), and titers increased with age (jonckheere test, p = 0.01). samples collected during 1996 (n = 79) were teste ...19989794654
