| antibodies to canine helminth parasites in asthmatic and nonasthmatic children. | we studied the prevalence of ige and igg antibodies to toxocara canis and dirofilaria immitis, helminth parasites of dogs, in asthmatic and nonasthmatic children born and raised in hawaii. the serologic pattern of the two groups was found to differ significantly. of the 80 asthmatic subjects, 45.0% had ige antibody and 17.5% igg-precipitating antibody to one or both parasites. in contrast, of the 96 nonasthmatic children studied 7.5% were positive for ige antibody and 31.3% positive for igg anti ... | 1981 | 7251191 |
| 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 ... | 2010 | 20566366 |
