| comparative histochemical observations on the excretory system of helminth parasites. | the excretory canals of ascaridia galli (nematoda) and the protonephridial ducts of cotylophoron cotylophorum (trematoda) and raillietina cesticillus (cestoda) have been studied with regard to the histochemical localization of lipids, carbohydrates and hydrolytic enzymes. distinct excretory organs are absent in the acanthocephalan centrorhynchus corvi. triglycerides, phospholipids and lipoproteins are seen in association with the wall of excretory canals of a. galli and r. cesticillus, and phosp ... | 1977 | 196423 |
| [influence of ascaridia-galli invasion on amino acid, protein and aminotransferase (gop, gtp) levels and activities in chickens]. | a negative influence of the helminths ascaridia galli on the level of free plasma amino acids and aspartate and alanine aminotransferase activities was demonstrated in the host chick serum. despite the above negative influence single experimental ascaridia galli invasion failed to influence the serum protein level or weight increments in chicks. at low invasion intensity the experimental chicks were able to compensate for the pathogenic effect of the helminth ascaridia galli, manifested by decre ... | 1977 | 411227 |
| [observations on the second moult of the larvae of ascaridia galli (author's transl)]. | in ascaridia galli larvae artificially hatched after 11 and 12 days of incubation at 25 degrees c, in larger frequency than in larvae hatched either after 10 and after 14 days of incubation, two different cuticles detached from their bodies were observed. these two detached cuticles indicate that such larvae had undergone two moults before hatching and, consequently, that the infective stage of a. galli is the third larval stage. | 1977 | 603203 |
| [facts that explain the host specificity of helminths]. | extracts from larvae of trichinella spiralis, mature ascaridia galli and ascaris suum and blood sera of their possible hosts (rats, pigs, chicks, guinea pigs, mice and men) were investigated by the method of electrophoresis in polyacrylamide gel. the protein component was found to be most identical in helminth and its obligate host. the host specificity is supposed to depend on the community of the protein content of the parasite and its host. the data on the difference in protein spectra are gi ... | 1978 | 643309 |
| ultrastructure of intestinal cells of heterakis gallinarum. | ultrastructure of intestinal cells of heterakis gallinarum is described and compared with that of ascaridia galli from ecomorphological point of view. the great analogy in bionomy and ecology of both worms is reflected in the great analogy of ultrastructural construction. a new organoid in the intestinal cells of h. gallinarum, hitherto unknown among nematodes, is also described. it is of a vacuole-like shape running in stripes close under the terminal bar. the paper is also meant to be a supple ... | 1978 | 697114 |
| [micromorphological study of the skin-muscular sac of the nematode ascaridia galli exposed to anthelmintic compounds]. | the effect of antihelmintic compounds on the cuticle, hypoderm and muscular cells of ascaridia galli was investigated in vitro. morphological changes were studied by means of light microscopy. the most pronounced changes in the musculocutaneous sac were found to be caused by santonin, hetrasan, piperasin and phenasal. less effective are phenotiasin, naphtamon and enteroseptol. | 1978 | 704139 |
| [effect of the ph of ascaridia galli egg culture medium on the experimental infection in chickens]. | 1. a prolonged preservation of ascaridia galli eggs in acid medium when cultivating them under laboratory conditions inhibits considerably the establishment of ascaridia galli in the organism of chickens. the neutralization of medium of egg cultivation 3 days before their application for infesting facilitates the increase of larvae established in the organism. 2. in chickens invaded with ascaridia galli eggs cultivated in medium with ph 8.0, larvae develop in the period of 7--21 days of invasion ... | 1978 | 32803 |

| prevalence of helminth parasites of domestic fowl (gallus domesticus) in uganda. | a survey of helminth parasites of domestic fowl carried out in uganda between 1977 and 1980 showed a high prevalence in both broiler and local poultry. nematodes especially ascaridia galli and heterakis spp. were most prevalent in both groups of birds. syngamus trachea and capillaria spp. also occurred in both groups. strongyloides avium was found only in broiler birds and gangylonema ingluvicola only in local birds. railletina spp. were the only cestodes found and their prevalence was high in b ... | 1982 | 7157477 |
| efficacy of fenbendazole against helminth parasites of poultry in uganda. | fenbendazole 4% (panacur, hoechst) administered in feed was used to treat chickens infected with ascaridia galli, heterakis gallinarum and railletina spp. it was also used to treat syngamus trachea in broiler birds. there was a marked drop in helminth egg counts in the faeces on the second day of treatment and the faeces became negative by the seventh day after the last treatment. post-mortem examination 15 to 21 days later showed that the drug was 100% effective against ascaridia galli and hete ... | 1982 | 6750887 |
| flubendazole: safety regarding egg production and reproductive performance of breeder chickens. | in a comparative field trial, 5,950 meat breeder chickens were medicated via feed for 7 consecutive days with 60 ppm of the anthelmintic flubendazole. this treatment cured the birds of an infection with ascaridia galli and capillaria obsignata. a slight but transitory diarrhea was observed in treated chickens. the applied medication did not unfavorably affect egg production, fertility, or hatchability. | 1983 | 6847549 |
| purification and characterisation of tubulin from the parasitic nematode, ascaridia galli. | we have developed a method for the purification of tubulin from a parasitic nematode using deae-sephadex column chromatography and temperature-dependent assembly. the resulting microtubules were morphologically similar to those obtained from mammalian brain. the nematode tubulin showed similar properties to mammalian tubulin on one and two dimensional polyacrylamide gels, although certain electrophoretic conditions revealed a slight difference in the alpha-tubulins from mammals and nematodes. th ... | 1983 | 6888427 |
| metabolism of amino acids in ascaridia galli: transamination. | ascaridia galli, using 2-oxoglutarate as an acceptor, transaminates alanine and aspartate at significantly high rates. among other amino acids valine, phenylalanine, leucine, isoleucine, arginine, tyrosine and methionine are metabolised at moderate rates while lysine, serine, threonine, cysteine, glycine, histidine, tryptophan, dopa and gaba appear to be inert in this respect. body parts mimic the whole worm in the pattern of transamination of various amino acids with the exception of methionine ... | 1983 | 6140798 |

| monoamine oxidase in adult ascaridia galli. | monoamine oxidase (mao), catalysing oxidative deamination of biogenic monoamines, has been detected in adult ascaridia galli. mao was present in mitochondria and deaminated noradrenaline at the maximal rate, although serotonin, adrenaline, tyramine and dopamine were also degraded but more slowly. of the organs studied, the body wall, female reproductive organ and intestine, the body wall (containing neuronal structures) showed highest mao activity. km value for chick ascarid mitochondrial mao us ... | 1983 | 6668418 |
| parasitic infections of the grey-breasted helmet guinea-fowl (numida meleagris galeata) in nigeria. | the major helminth parasites found in wild, semi-wild and golden sovereign stock guinea fowl were heterakis gallinarum, ascaridia galli, capillaria caudinflata, raillietina tetragona and r. echinobothrida, while eimeria species was the most important gastro-intestinal protozoan parasite. the incidence of the latter was higher in the semi-wild stock than in the wild stock. necropsy of dead guinea-fowl indicated that a. galli, h. gallinarum and eimeria species were indeed responsible for their dea ... | 1983 | 6683038 |
| nippostrongylus brasiliensis and ascaridia galli: mitochondrial respiration in free-living and parasitic stages. | aerobic respiratory pathways have been delineated and respiratory efficiency has been assessed in mitochondria isolated from embryonated eggs, infective larvae, and adult nippostrongylus brasiliensis and ascaridia galli. mitochondrial respiration in free-living stages of n. brasiliensis is mediated mainly by a mammalian-like antimycin a- and cyanide-sensitive pathway; specific respiratory activity is high and oxidative phosphorylation efficient. in mitochondria of adult n. brasiliensis, antimyci ... | 1983 | 6683662 |
| protofilament number in microtubules in cells of two parasitic nematodes. | the parasitic nematodes, ascaridia galli and trichostrongylus colubriformis, were prepared for electron microscopy with fixatives containing tannic acid, which allowed their microtubule protofilament number to be examined. in contrast to many mammalian tissues, the nematodes did not contain microtubules with 13 protofilaments. ascaridia galli contained microtubules with 11 protofilaments in all tissues examined, including nerve, intestinal, pharyngeal, and hypodermal cells. trichostrongylus colu ... | 1983 | 6687065 |
| ascaris lumbricoides and ascaridia galli: biogenic amines in adults and developmental stages. | ascaris lumbricoides var. hominis and ascaridia galli contain 5-hydroxytryptamine, histamine, dopamine, and norepinephrine. the chick parasite showed lower levels of monoamines compared to human ascaris. amine concentrations in females were higher than in males. in all specimens, 5-hydroxytryptamine was the highest while norepinephrine was found to be uniformly low. the female reproductive organ contained the maximum amount of dopamine while intestine was rich in histamine. a progressive increas ... | 1984 | 6692882 |
| nematoda: aerobic respiratory pathways of adult parasitic species. | aerobic respiratory pathways have been compared in adult parasitic nematodes, including trichostrongylus colubriformis, nippostrongylus brasiliensis, ostertagia ostertagi, cooperia oncophora, haemonchus contortus, oesophagostomum venulosum, chabertia ovina, dictyocaulus filaria, dictyocaulus viviparus, and ascaridia galli. respiration was measured in both whole worm or tissue homogenates and isolated mitochondrial fractions, and delineated into the mammalian type or alternative respiratory pathw ... | 1984 | 6692887 |
| a comparison of the interaction of anthelmintic benzimidazoles with tubulin isolated from mammalian tissue and the parasitic nematode ascaridia galli. | colchicine and a range of anthelmintic benzimidazoles inhibited the in vitro polymerization of tubulin purified from the parasitic nematode ascaridia galli. in most cases, this inhibition was more pronounced than that detected when these drugs were incubated with tubulin purified from mammalian tissue. in particular, oxfendazole and thiabendazole had virtually no effect on mammalian tubulin assembly whereas they were both good inhibitors of nematode tubulin polymerization. electron microscopic e ... | 1984 | 6712717 |
| cyclic amp-dependent and independent protein kinases in ascaridia galli. | the occurrence of multiple protein kinases, distinguished with respect to molecular weight and preference for acceptor proteins, was demonstrated in ascaridia galli. the molecular weights of the cyclic amp-dependent protein kinase and of phosvitin kinase i and ii - both independent of cyclic amp-were determined to be 160000, greater than 200000 and 40000, respectively. the cyclic amp-dependent protein kinase preferred histones and kemptide as acceptor substrates; stimulation of enzyme activity w ... | 1984 | 6090901 |
| methyl 5(6)-4-2-pyridyl piperazino carbamoyl benzimidazole-2-carbamate--a new broad spectrum anthelmintic. | methyl 5(6)-4-2-pyridyl piperazino carbamoyl benzimidazole-2-carbamate (cdri comp. 81-470) was tested against various nematode and cestode infections in different experimental and domestic animals. the compound showed 100% effectivity against adult of ancylostoma ceylanicum (hookworm) in hamsters (6.25 mg/kg p.o. x 1), nippostrongylus brasiliensis (trichostrongylid) in rats (100 mg/kg p.o. x 3), hymenolepis nana (cestode) in rats (25 mg/kg p.o. x 1) and syphacia obvelata (oxyurid) in mice (12.5 ... | 1984 | 6150623 |

| characterization of mitochondrial monoamine oxidase of ascaridia galli. | oxidative deamination of various biogenic monoamines by ascaridia galli monoamine oxidase (mao) was blocked by different mammalian mao inhibitors, namely, iproniazid, trans-pcp, nialamide and pargyline and the blockade was observed to be time as well as concentration dependent. the binding of inhibitors with chick ascarid mao was of the irreversible type and the nature of the inhibition was competitive. pargyline showed lowest i50 (8 microm) and ki (12 microm) values. chlorgyline and deprenyl at ... | 1985 | 4031449 |
| connections between ascaridia galli and the bacterial flora in the intestine of hens. | parasitological dissections of 502 intestinal tracts of hens deriving from big private chicken-farms have been done. in the jejunum of 146 hosts (ext. 29.1%) from 1 to 21 individuals of a. galli were detected. using bacterial selective media and biochemical tests, the microorganisms from the hen's intestinal tracts as well as from the cuticle surface of the nematodes were identified. among them were: grampositive (+) lactobacillus, bacillus, staphylococcus, streptococcus, micrococcus, sarcina, c ... | 1985 | 4061960 |
| effect of some anthelmintics on malate dehydrogenase activity and mortality in two avian nematodes ascaridia galli and heterakis gallinae. | cambendazole and tiabendazole at 10(-4) m concentrations caused mortality in both the parasites after 10 min and 20 min, respectively. h. gallinae was killed by 10(-4) m haloxon but a. galli remained alive even after 60 min exposure. the effect of these drugs was found to be irreversible since no resumption of activity was observed when the parasites were returned to normal saline solution. the ratio of oxaloacetate reduction to malate oxidation in the homogenates of a. galli and h. gallinae was ... | 1986 | 3777528 |
| dose-titration of fenbendazole in the treatment of poultry nematodiasis. | broiler chickens were fed ad libitum diets containing fenbendazole at various concentrations and durations for the removal of adult ascaridia galli, heterakis gallinarum, and capillaria obsignata. all regimens were 100% effective against a. galli. fenbendazole at doses of 80 ppm for 3 days and 48 or 30 ppm for 5 days was 100% effective against h. gallinarum. c. obsignata was not removed completely by any regimen, but greater than or equal to 95% effectiveness was seen in birds given fenbendazole ... | 1986 | 3814008 |
| in vitro hatching of the infective eggs of ascaridia galli in tissue extracts. | extracts of proventriculus (pe) and small intestine (ie) of fowl were used, for the first time, as media for the in vitro hatching of infective eggs of ascaridia galli. hatching was successful in a mixture of equal parts of pe and ie (mip) under normal air and under different concentrations of co2, but not under 100% co2. a very highly significant retardation (p less than 0.001) in the rate of hatching appeared as the concentration of co2 was increased, indicating that high levels of co2 inhibit ... | 1987 | 3113042 |
| the occurrence and localization in trypanosomes and other endo-parasites of an antigen cross-reacting with mitochondrial antibodies of primary biliary cirrhosis. | 1. a mitochondrion-associated antigen to primary biliary cirrhosis (pbc) in man has been shown by solid-phase radioimmunoassay and immunoautoradiography to occur in several parasitic protozoa (trypanosoma, plasmodium and eimeria spp.) and in the helminths ascaridia galli and nippostrongylus brasiliensis. 2. stercorarian trypanosomes and t. brucei procyclics, with more highly-developed mitochondria, appear to contain more pbc antigen than the salivarian trypomastigote, in accordance with the know ... | 1987 | 3427933 |
| the effect of piperazine adipate and parbendazole on the carbohydrate metabolism of ascaridia galli and heterakis gallinae. | carbohydrate metabolism of ascardia galli and heterakis gallinae was studied after their exposure in vitro to 10(-2) to 10(-5) m piperazine adipate and parbendazole for 10 to 60 min. following treatment with 10(-2) m piperazine adipate o2 uptake was reduced by 87% in a. galli and 70% in h. gallinae, while parbendazole (10(-2) m) reduced o2 uptake by 70% and 86%, respectively. glycogen contents were reduced significantly by 10(-2) m piperazine adipate in both the worms, while lactic acid level wa ... | 1987 | 3445963 |
