| diethylcarbamazine-induced dirofilaria immitis larval death, as indicated by immunoglobulin e concentration, in dogs with concurrent ancylostoma caninum infection. | immunoglobulin e is produced in response to parasitic nematodes that undergo blood and tissue migrations. results of our previous studies indicated that ige and igg respond to dirofilaria immitis in experimentally infected dogs. to determine the association between treatment with the larvicide, diethylcarbamazine (dec), and antibody responses and to examine the potential influence of infection with a nonfilarid intestinal nematode on isotype-specific immune responses, we monitored, by use of iso ... | 1995 | 7717581 |
| protective immunity to haemonchus contortus induced by immunoaffinity isolated antigens that share a phylogenetically conserved carbohydrate gut surface epitope. | whole gut homogenates of the blood-sucking nematode haemonchus contortus induce protective immunity in goats, and some of these gut ag are conserved among related parasitic nematode species. to identify gut ag that induce protective immunity and have phylogenetically conserved epitopes, mab were made to gut-surface ag of h. contortus. forty-nine mab reacted with microvilli of the parasite gut. two of these mab (42/10.6.1 and 42/53.3.5) were analyzed here. both of the mab bound to the microvillar ... | 1993 | 7693812 |
| seasonal influence on human enteric infection by ancylostoma caninum. | ancylostoma caninum, the cosmopolitan canine hookworm prevalent in domestic pets throughout northeastern australia, has been identified as a cause of obscure abdominal pain. to investigate the influence of climate on putative and confirmed human infections, a retrospective study of patients with eosinophilic enteritis and established infections was undertaken to identify the monthly and seasonal rates. the numbers seen each month were maintained throughout most of the year but decreased in june ... | 1995 | 7677217 |
| an investigation into the health status and diseases of wild dogs (lycaon pictus) in the kruger national park. | many factors have been cited as possible reasons for the decline in the number of wild dogs (lycaon pictus), but few studies have provided supportive data. between 1990 and 1993, the dynamics of 10 wild dog packs in the southern district of the kruger national park in south africa were monitored. casual observations of the causes of disease and mortality in the entire population were also recorded. during the same period, 46 wild dogs were immobilised, weighed, and subjected to physical examinat ... | 1995 | 7629782 |
| ancylostoma caninum anticoagulant peptide: a hookworm-derived inhibitor of human coagulation factor xa. | human hookworm infection is a major cause of gastrointestinal blood loss and iron deficiency anemia, affecting up to one billion people in the developing world. these soil-transmitted helminths cause blood loss during attachment to the intestinal mucosa by lacerating capillaries and ingesting extravasated blood. we have isolated the major anticoagulant used by adult worms to facilitate feeding and exacerbate intestinal blood loss. this 8.7-kda peptide, named the ancylostoma caninum anticoagulant ... | 1995 | 7597095 |
| neutrophil inhibitory factor prevents neutrophil-dependent lung injury. | neutrophil inhibitory factor (nif) is a recently cloned 41-kda protein from the canine hookworm that binds cd11b/cd18 and inhibits cd11b/cd18-dependent neutrophil adhesion. we evaluated nif's effects on neutrophil-dependent lung injury in guinea pigs. pulmonary vascular endothelial cd54 (icam-1) was induced in buffer-perfused lungs by 90-min exposure to 1000 u/ml tnf-alpha. human neutrophils (2 x 10(7)) were added to the perfusate and activated by 5 x 10(-9) pma; in some lungs, the neutrophils w ... | 1995 | 7594491 |
| the a-domain of beta 2 integrin cr3 (cd11b/cd18) is a receptor for the hookworm-derived neutrophil adhesion inhibitor nif. | the a-domain is a approximately 200-amino acid peptide present within structurally diverse proadhesive proteins including seven integrins. a recombinant form of the a-domain of beta 2 integrins cr3 and lfa-1 has been recently shown to bind divalent cations and to contain binding sites for protein ligands that play essential roles in leukocyte trafficking to inflammatory sites, phagocytosis and target cell killing. in this report we demonstrate that the neutrophil adhesion inhibitor, nif produced ... | 1994 | 7528750 |
| characterization and localization of cathepsin b proteinases expressed by adult ancylostoma caninum hookworms. | the hookworm ancylostoma caninum induces human eosinophilic enteritis (ee), probably via allergic responses to its secretions. cysteine and metallo-proteinases may be the components of these secretions that elicit hypersensitivity reactions. in order to characterize genes encoding cysteine proteinases (cp) secreted by a. caninum, an adult hookworm cdna library was constructed and screened with a cloned fragment of a hookworm cp gene. this fragment was obtained using consensus oligonucleotide, cp ... | 1995 | 7477098 |
| [helminths of the common fox (vulpes vulpes l.) from the massif central (france) (author's transl)]. | sixty nine wild foxes originating from auvergne for the period january 1977 to january 1978 have shown intestinal parasites in the proportion of 76,8 per cent. 59,4 per cent are invaded with cestodes; 72,4 per cent with nematodes and none with trematodes. the list of the identified species is following: 1. cestodes. a) adults and fertile forms of: mesocestoides litteratus in 27,5 per cent of the hosts; taenia crassiceps in 15,9 p.c.; t. polyacantha in 27,5 p.c.; echinococcus multilocularis in 7, ... | 1980 | 7458165 |
| scanning electron microscopy of the penetration of newborn mouse skin by strongyloides ratti and ancylostoma caninum larvae. | the scanning electron microscopical appearances of infective larvae of strongyloides ratti and ancylostoma caninum have been described. particularly noteworthy was the tail of s. ratti which was found to have a distal aperture surrounded by a row of eight projections. the penetration of larvae through newborn mouse skin was investigated. s. ratti larvae forced its way rapidly and directly through the stratum corneum. no larvae of a. caninum were observed in stages of partial penetration but the ... | 1980 | 7434072 |
| experimental infection of chickens with ancylostoma caninum: migration and distribution of larvae in tissues. | two hundred one-day-old male white leghorn chickens (gallus domesticus) divided into 4 groups were inoculated with a single dose of 500, 1000, 2000 or 4000 filariform larvae of ancylostoma caninum. larval recoveries were made from different tissues at intervals from 4 hours to 72 hours after infection. larval migration in the heart took place within 4 hours in all the groups except group a with 500 larvae and in thoracic muscle at 8 hours. larvae also migrated into liver, lungs and neck muscle w ... | 1980 | 7410806 |

| pathogenicity of hookworms. the significance of population regression for the pathogenicity of hookworms. | a method is described to estimate the reduction of the hookworm population in the host during the infection period (population regression). a formula is proposed to estimate the average worm population during the infection period, on the assumption that a decreasing hookworm population causes a decrease in daily blood loss. daily blood loss per worm was calculated for ancylostoma caninum: 43 microliters; for a. ceylanicum: 14 microliters for a. braziliense: 5 microliters. accordingly hookworms ... | 1980 | 7210160 |
| a comparison of the sites of acid phosphatase activity in an adult filaria, setaria sp. and in some gastro-intestinal nematodes. | the histochemical localization of acid phosphatase in an adult filaria, setaria sp. obtained from the peritoneal cavity of a cow was closely examined and compared with that of adult nematodes parasitic in the host alimentary canal; special attention was paid to the intestine and body wall of the parasites. setaria sp. was found to show high acid phosphatase activity in the interchordal hypodermis of the body wall and uterine microfilariae, and similar activity is suspected to occur in the cuticl ... | 1980 | 7195002 |
| gastrointestinal helminth parasites of dogs in the western area--freetown (sierra leone). | a survey of faecal samples taken from 1277 dogs in the western area (freetown, sierra leone) revealed an infestation by ancylostoma caninum (46,1%), toxocara canis (13,5%), toxascaris leonina (5,9%), dipylidium caninum (3,8%), and spirocerca lupi (3,5%). sampling was made per rectum. the age of the dogs examined, both male and female, ranged from one month to fifteen years. the clinical picture of the dogs affected is described and methods of treatment are suggested. | 1982 | 7171367 |

| development and fate of the membranous organelles in spermatozoa of ancylostoma caninum. | during development membranous organelles first appeared in the primary spermatocytes of ancylostoma. they were derived from the golgi as two separate components. one component, an electron-dense spheroid, quickly fused with other newly-formed cup-shaped, membranous structures to form the asymmetrical organelles. initially the membranous organelles had a homogeneous matrix but later became filled with quantities to 6- 8-nm filaments. following the meiotic reduction divisions each cell assumed a b ... | 1982 | 7131188 |
| the function of microtubules during spermatogenesis of ancylostoma caninum. | ancylostoma caninum spermatogonia appeared as unspecialized cells with large nuclei and little cytoplasm when examined by electron microscopy. mitochondria and ribosomes were numerous but endoplasmic reticulum of either the rough or smooth variety was rarely observed. microtubules were abundant but were mostly concentrated in areas where the cells connected with a central cytoplasmic core, or rachis. microtubules present elsewhere in the cytoplasm were not associated with any particular organell ... | 1982 | 7131187 |
| anthelmintic activity of closantel against ancylostoma caninum in dogs. | the efficacy and minimum therapeutic dose of closantel, an injectable salicylanilide anthelmintic, was evaluated on adult ancylostoma caninum. doses of 7.5 and 10 mg/kg had a marked anthelmintic effect on adult stages, removing 99 and 98%, respectively. a second experiment tested the efficacy of closantel against hypobiotic larval stages of a. caninum. a dose of 20 mg/kg did not affect the abundance of arrested hookworm larvae or prevent their subsequent development, but it may have inhibited th ... | 1982 | 7119989 |
| experimental infection with ancylostoma caninum larvae in mice. vii. role of promethazine hydrochloride in the rejection of worm burden from the intestine. | acquired resistance of female swiss albino mice (6 to 8 weeks old) to ancylostoma caninum infection was demonstrated by the transfer of mesenteric lymph node cells (mlnc) from resistant (sensitised and promethazine treated), sensitised and untreated and non-sensitised and untreated donors to normal recipients of the same isogeneic strain. mlnc from sensitised and promethazine treated donors were more effective in suppressing the rejection mechanism of worm burden in recipients in comparison to t ... | 1982 | 7119431 |

| determination of the specific gravity of certain helminth eggs using sucrose density gradient centrifugation. | the specific gravities of ten species of helminth eggs were determined using sucrose density gradient centrifugation. fecal or egg concentrate was layered over a 3 to 54% sucrose density gradient. the gradient was then centrifuged at 800 g for 20 min, allowing 5 min for acceleration and 5 for deceleration. bands formed were identified and measured. refractive index was measured at the middle of narrow bands, or at the level at which the concentration of eggs was highest, in the case of wide band ... | 1982 | 6890102 |
| 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 |
| 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 |

| 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 |
| 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 |
| endotube-brush border complexes dissected from the intestines of haemonchus contortus and ancylostoma caninum. | a procedure for the blunt dissection of the syncytial intestine of haemonchus contortus to separate the endotube-brush border complex is described. a similar complex can be obtained from the partially cellular intestine of ancylostoma caninum. the structural features of the complexes from the two sources are compared. the main differences are in the retention of terminal bars by the endotube from a. caninum and in the extent and organization of the microfilaments associated with the basal side o ... | 1983 | 6684761 |
| ancylostoma caninum: a report on the peripheral eosinophilia in naive and immunized swiss albino mice. | the number of peripheral eosinophils was counted in female swiss albino mice on 1, 4, 9, 16 and 30 days after infection with various single (500, 1000 and 2000) and weekly repeated (500 + + 500 + 1000, 1000 + 1000 and 1000 + 1000 + 2000) doses of filariform ancylostoma caninum larvae. the eosinophil response was significantly higher in infected than in uninfected mice and reached a peak on day 16 in naive and day 4 and 9 in immunized mice. immunized mice were significantly more eosinophilic than ... | 1983 | 6662410 |
| 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 |
| 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 |
| 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 |

| 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 |
| 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 |
