| evaluation of serodiagnostic tests for visceral larva migrans. | four serologic techniques for the diagnosis of visceral larva migrans caused by toxocara canis, namely indirect hemagglutination (iha), bentonite flocculation (bf), enzyme-linked immunosorbent assay (elisa), and double diffusion in agar (ouchterlony), were evaluated using sera sent to the center for disease control from patients with a presumptive diagnosis of visceral larva migrans (vlm). patients having 5-6 of the clinical or laboratory criteria for vlm were designated as cases while those wit ... | 1978 | 98065 |
| serologic differentiation of adult toxocara and ascaris. | the antigenic analysis of toxocara canis a causative agent of visceral larva migrans and ascaris suum has been carried out. agar gel double diffusion techniques and its modifications were employed to determine whether or not crude antigens, obtained from the adult parasites: (a) contained components unique for each, (b) could be used to differentiate the parasites serologically. adult toxocara canis and ascanis suum antigens used in this study were found to contain several unique antigenic compo ... | 1979 | 121695 |
| the efficacy of amidantel, a new anthelmintic, on hookworms and ascarids in dogs. | amidantel is a new anthelmintic from a new chemical class with an interesting anthelmintic spectrum. in dogs amidantel is highly effective in a single oral dose of 25 mg/kg against both hookworm species, ancylostoma caninum and unicinaria stenocephala. in toxascaris leonina infected dogs a complete cure rate was achieved with a single oral dose of 50 mg/kg. similar results were obtained with 8 mg/kg administered three times per day. the most sensitive parasite to amidantel was found to be toxoca ... | 1979 | 295548 |
| comparative evaluation of 7 helminth antigens in the enzyme-linked immunosorbent assay (e.l.i.s.a.). | 112 sera from europeans with parasitologically proven helminthiasis were tested in the enzyme-linked immunosorbent assay (e.l.i.s.a.) against 6 crude extracts of various helminths (2 of adult worms: dipetalonema viteae, fasciola hepatica; 3 of eggs: ascaris suum, toxocara canis, schistosoma mansoni; and of echinococcus granulosus scolices) and against bovine hydatid fluid. each serum was tested simultaneously at a fixed dilution of 1:160 against all antigens. extensive cross-reactions were obser ... | 1979 | 92420 |
| eosinophilic meningitis: a suspected case of angiostrongylosis found in shizuoka prefecture, honshu, japan. | a patient with eosinophilic meningitis in shizuoka prefecture, honshu, japan had nausea, vomiting and headache on admission; laboratory examinations revealed leukocytosis with eosinophilia. eight days later neck stiffness appeared. lumbar puncture showed an increase of the initial pressure in association with eosinophilic pleocytosis in the spinal fluid. the possibility of angiostrongylosis was considered because the patient had eaten raw slugs for 4 years as a remedy for lumbago. although the s ... | 1979 | 434313 |
| a survey of gastro intestinal helminth parasites of stray dogs in zaria, nigeria. | a survey of helminth parasites in stray dogs was carried out in the zaria area. out of 180 dogs examined 65.6 per cent (118/180) were found positive for ancylostoma caninum, while toxocara canis and trichuris vulpis were detected in 41.1 per cent (74/180) and 13.9 per cent (25/180) respectively. other helminth parasites found taenia ovis 35 per cent (63/180) taenia hydatigena 67.8 per cent (122/180), echinococcus granulosus 0.006 per cent (1/180) and dipylidium caninum 97.8 per cent (176/180). | 1979 | 452351 |
| epidemiological characteristics and clinical findings in patients with serologically proven toxocariasis. | the enzyme-linked immunosorbent assay (elisa) using toxocara canis larva-specific antigens was used to confirm a presumptive clinical diagnosis of visceral larva migrans in patients whose serum specimens were submitted to the center for disease control. the clinical and epidemiological characteristics of patients with diagnostic elisa titres (greater than or equal to log2 5) were compared with patients who had less or no detectable antibody. the typical patient with serologically confirmed toxoc ... | 1979 | 473320 |
| effect of fenbendazole on toxocara canis larvae in tissues of infected dogs. | the effect of fenbendazole therapy was studied in six dogs fed 10,000 embryonated toxocara canis eggs. at 47 days after they were fed t canis, four dogs were given fenbendazole in two divided doses totaling 50 mg/kg of body weight each day for 14 days. two infected dogs were not given fenbendazole. all dogs were necropsied at the end of treatment and the foci were counted in the lungs; their skeletal muscles were digested in 1% trypsin for the recovery of larvae. the t canis larvae were not reco ... | 1979 | 475114 |
