trichinosis surveillance, united states, 1986.trichinella spiralis is a parasite of carnivorous animals that causes the disease trichinosis. in the united states, people become infected by eating poorly cooked pork products or wild animal meat that is infected with the parasite. although fewer than 100 cases per year are reported to cdc, trichinosis continues to persist as a public health problem in this country. public health officials believe that the reported cases represent only a fraction of the total number of cases, since many of the ...19883148105
prevalence of antibodies to toxoplasma gondii and trichinella spiralis in 509 pigs from 31 farms in oahu, hawaii.serum samples from 509 pigs from 31 farms in oahu, hawaii were examined for antibodies to toxoplasma gondii using the agglutination test in dilutions of 1:25, 1:50, and 1:500 and for trichinella spiralis using the enzyme-linked immunosorbent assay. toxoplasma gondii antibodies were found in 48.5% of pigs. antibody titers were: 5.1% positive at 1:25 dilution, 28.6% positive at 1:50 dilution and 14.7% positive at 1:500 dilution. the prevalence of toxoplasma gondii antibodies in garbage-fed pigs (6 ...19921496803
molecular differentiation and phylogenetic relationships of three angiostrongylus species and angiostrongylus cantonensis geographical isolates based on a 66-kda protein gene of a. cantonensis (nematoda: angiostrongylidae).the phylogenetic relationships and molecular differentiation of three species of angiostrongylid nematodes (angiostrongylus cantonensis, angiostrongylus costaricensis and angiostrongylus malaysiensis) were studied using the ac primers for a 66-kda protein gene of a. cantonensis. the ac primers successfully amplified the genomic dna of these angiostrongylid nematodes. no amplification was detected for the dna of ascaris lumbricoides, ascaris suum, anisakis simplex, gnathostoma spinigerum, toxocar ...201020566366
the cockroach as a host for trichinella and enterobius vermicularis: implications for public health.cockroaches are known carriers of bacteria and fungi that produce disease in humans. however, the link between pathogenic helminths and cockroaches has not been fully explored. this preliminary study demonstrates trichinella and enterobius (also known as human "pinworm") infestation in cockroaches obtained from a grade school and hospitals in hawaii. this is the first report of trichinella and enterobius infestation in naturally occurring cockroaches. these results suggest that roachs are an una ...200415124739
