| comparison of immune response in swiss albino mice due to single and repeated doses of infective ancylostoma caninum larvae after subcutaneous inoculation. | migratory behaviour of ancylostoma caninum larvae and host responses were studied in four groups of swiss albino mice infected subcutaneously with single doses of 1,000, 2,000 and multiple doses of 500 + 500, 500 + 500 + 1,000. after the 1st day most of the larvae found in muscles in all the groups. there is no significant difference in the migratory behaviour and/or the adoptive pattern of larvae in both the singly and multiply infected animals. | 1989 | 2809186 |
| efficacy of various anthelmintics against third-stage larvae of ancylostoma caninum in the brain of mice. | in an experimental larval infection of ancylostoma caninum in mice, the efficacy of various anthelmintics against the larvae migrated and established in the brain is reported for the first time. albendazole and flubendazole were the most effective drugs. thiabendazole, benacil, phenacizole, oxfendazole and mebendazole showed significant larvicidal activity. tetramisole, levamisole, fenbendazole, sch 18099, pyrantel pamoate, morantel tartrate and oxantel pamoate did not show any significant activ ... | 1988 | 3372978 |
| transmission of ancylostoma caninum and alaria marcianae in coyotes (canis latrans). | one of seven female coyotes (canis latrans) captured in webb county, texas during september 1986 and confined and mated in holding facilities at millville, utah whelped the following spring. the maternal female (greater than 5-yr-old) and her five neonates were killed at 22 days postparturition. all were infected with adult ancylostoma caninum and were passing eggs in their feces. also, the neonates and maternal female were infected with immature and adult alaria marcianae, respectively. these f ... | 1988 | 3411716 |
| serum enzymes and worm load in mice infected with repeated doses of ancylostoma caninum larvae. | the alterations of serum enzymes induced in the host system of swiss albino mice by infection with ancylostoma caninum larvae have been studied in multiple doses of infection. it was found that the level of transaminases, alkaline phosphatase and amylase increased significantly throughout the infection period when compared with controls. in infected animals, increase of enzymes was influenced by the host-parasite interactions caused due to the retained concentration of larval antigens. | 1988 | 2457613 |
| changes in serum enzyme activities in mice infected with single doses of ancylostoma caninum larvae. | aspartate transaminase, alanine transaminase, alkaline phosphatase and amylase levels were significantly increased in experimental female swiss albino mice infected with single doses of 500, 1,000 and 2,000 larvae of ancylostoma caninum. increase of enzyme levels is due to the leakage of large amounts of enzymes into the blood. the necrosis of cells during intestinal and extra intestinal phases of ancylostomiasis in mice is directly responsible for the increase of enzymes. | 1987 | 2437181 |
| maternal transmission by alaria marcianae (trematoda) and the concept of amphiparatenesis. | the term amphiparatenic host was coined originally for hosts of alaria marcianae that as adults are paratenic hosts, but as juveniles serve as definitive hosts. in this study the concept of amphiparatenesis is placed in a theoretical context, maternal transmission shown to be the basic mechanism, and the concept extended to include toxocara canis, t. cati, t. pteropodis, neoascaris vitulorum, ancylostoma caninum, uncinaria lucasi, various species of strongyloides, pharyngostomoides procyonis, an ... | 1987 | 3572644 |
| helminth parasites of the coyote (canis latrans) in tennessee. | from 1980 to 1984, 267 coyotes (canis latrans) from tennessee were examined for helminth parasites. hearts were examined for the presence of dirofilaria immitis, diaphragms for trichinella spiralis, and digestive tracts for other helminths. six species were found including 5 nematodes (d. immitis, physaloptera rara, trichuris vulpis, ancylostoma caninum, and toxascaris leonina) and 1 cestode (taenia pisiformis). univariate and multivariate statistical techniques were used to assess parasite prev ... | 1987 | 3585628 |

| population dynamics across selected habitat variables of the helminth community in coyotes, canis latrans, from south texas. | the effects of selected intrinsic variables operating on host subpopulations and of extrinsic variables across the collective host population on the distributions of 10 common helminth species from coyotes in south texas were compared. the intrinsic variables of host sex and presence and severity of sarcoptic mange had little effect on the distributions of most helminth species. the combined influences of (1) seasonal changes across the collective host population and (2) host subpopulations deli ... | 1984 | 6512639 |
| effect of spleen extracts on the immune response in chickens to ancylostoma caninum larvae. | spleen extracts from wlh chickens nonsensitized and sensitized by repeated infections of ancylostoma caninum larvae were injected separately into isologous recipients. extracts from donors infected with repeated high dose (250 + 250 + 500) and low dose (125 + 125 + 250) of larvae induced a significant acquired protective immune response when compared to controls which received normal extracts. no significant difference was observed between the two experimental groups. the filariform ancylostoma ... | 1984 | 6527002 |
| prevalence of toxocariasis and echinococcosis among dogs in the niger delta. | a sample of 60 dogs in the port harcourt area of the niger delta was examined for intestinal parasites. the high prevalence rates of toxocara canis (56.6%) and echinococcus granulosus (85.0%) in the area are discussed in relation to public health. other parasites found in dogs include toxascaris leonina (3.3%), uncinaria stenocephala (70.0%), dipylidium caninum (88.3%), trichuris vulpis (56.7%), ancylostoma caninum (65.0%) and taenia hydatigenia (43.3%). | 1984 | 6530709 |
| infectivity of ancylostoma caninum in dogs by different routes of inoculation. | infectivity of a. caninum in dogs inoculated with 500 larvae by different routes (percutaneous, subcutaneous, intravenous, per os, through a stomach tube and foot pad) was studied by ascertaining the worm burden at necropsy 21-27 days post-infection. infection through foot-pads yielded the maximum number of worms. the percentage of worm establishment using foot-pad inoculation was 73.8%, followed by subcutaneous (49.0%), percutaneous (45.0%) and per os (35.0%) routes. these results show that act ... | 1984 | 6542725 |
| serum protein profile of mice during infection with of ancylostoma caninum and after the administration of tetramisole and levamisole. | serum protein changes in mice following ancylostoma caninum larval infection were observed as decrease in albumin, gamma globulin and increase in beta globulin. these serum protein components showed a tendency to return back to their normal levels after the administration of effective anthelmintic such as tetramisole or levamisole to the infected mice. the increased level of beta globulin after treatment although decreased but did not return to its normal level within 14 days observation period. | 1984 | 6084695 |
| a possible explanation for the synergism between mixed t- and b- cell populations in mice adoptively immunized with ancylostoma caninum. | ancylostoma caninum--mouse model was employed to study the cellular cooperation in the adoptive immune response. the syngeneic recipient mice were intraperitoneally injected once or twice with mixtures of thymus and bone marrow cells from infected (with 500 or 2000 larvae) and uninfected donors. the experimental recipients expelled and/or destroyed the challenge larval burden more readily and at a greater rate than the controls with unsensitized cells. the cooperation between sensitized thymus a ... | 1984 | 6335517 |
| anthelmintic effect of febantel/praziquantel paste in dogs and cats. | a paste formulation of 3.4% febantel and 0.34% praziquantel was given in soft food at a rate of 0.29 g/kg of body weight, once daily for 3 days to dogs and cats. eleven of 12 dogs were naturally infected with ancylostoma caninum, 10 with trichuris vulpis, 2 with toxocara canis, 5 with taenia sp, and 3 with dirofilaria immitis. ten of 11 cats were naturally infected with toxocara cati, 2 with ancylostoma tubaeforme, 3 with taenia sp, 5 with capillaria aerophila, and 1 with paragonimus kellicotti. ... | 1984 | 6703448 |
| rapid expulsion of ancylostoma caninum larvae due to previous infection with hymenolepis nana deshelled eggs. | mice initially infected with single and repeated doses of hymenolepis nana deshelled eggs produced rapid and significant expulsion of challenged ancylostoma caninum larvae. absolute protective response was observed 8 days after initial infection (at 96 hours after challenge) in both singly and repeatedly infected groups probably due to high titres of heterologous reacting antibodies. | 1984 | 6715879 |

| transfer of delayed hypersensitivity through repeatedly sensitized peritoneal exudate cells during experimental ancylostomiasis in mice. | current investigations using sensitized peritoneal exudate cells from mice infected repeatedly with ancylostoma caninum larvae supply the evidence that these cells have the capability to transfer passive immunity to isogeneic recipients in contrast to normal cells from uninfected donors. high doses of sensitization to donors and a lapse of time between the expansion and proliferation of cells in the recipients provide a rather strong immunological readiness to expel/destroy the worm burden. the ... | 1983 | 6862315 |
| experimental ancylostomiasis in chickens: effect of various dose of infective ancylostoma caninum larvae on their migration and distribution. | white leghorn chickens, when infected with repeated doses of ancylostoma caninum larvae, expel the larvae at a faster rate than when infected with a single dose. this suggests that the initial dose induces some resistance in the host. an initial dose of 1000 and 2000 larvae, followed by a 2nd dose of the same order, induces resistance in the alimentary tract causing the entire larval burden either to migrate to other tissues (organs) or to be expelled in 24 h. | 1983 | 6873246 |
| pattern of immune response in recipients after transfer of mesenteric lymph node cells sensitized with low and high doses of ancylostoma caninum. | cellular immune response was detected in female swiss albino mice with mesenteric lymph node cells during ancylostoma caninum infection. sensitized lymphocytes responded vigorously to a. caninum antigens and it was found that the cells (singly or repeatedly) sensitized with either low or high doses could confer adoptive protective immunity in recipients later challenged with a single dose of 500 a. caninum larvae. | 1983 | 6629209 |
| pulmonary superoxide dismutase activity in the mouse infected with ancylostoma caninum larvae. | albino mice were infected per os with 1000 infective larvae of ancylostoma caninum and pulmonary superoxide dismutase activity was studied after completion of lung migration. the total superoxide dismutase activity per mg of lung protein was elevated by 15% in infected mice. of the two forms of superoxide dismutases studied, that containing cu-zn was elevated by 44%. this suggests that a. caninum in mice may result in histopathological changes leading to transient pulmonary oxygen toxicity. | 1983 | 6630995 |
