Nippostrongylus brasiliensis and Ascaridia galli: Characterization of peroxisomes
Experimental Parasitology, 1990A method is described for the isolation of peroxisomes from mitochondria-enriched fractions obtained from both species of nematodes. The distributions of these organelles are characterized after density gradient centrifugation in sucrose or Percoll by urate oxidase and catalase activities.

Ascaridia galli isolates with ITS1-5.8rRNA-ITS2 fragment homologous to Ascaridia columbae
Acta Parasitologica, 2018Abstract Ascaridia (A.) galli is one of the most commonly occurring nematodes in poultry worldwide, often in hens and broiler chickens. The infection with Ascaridia galli in free-range chickens was even 70%. There is not much information about A. galli genetic features. The present study was conducted to assess the genetic diversity of A.

Ascaridia galli: Trypsin and chymotrypsin inhibitors
Experimental Parasitology, 1976Abstract (1) Extracts of Ascaridia galli , a nematode parasite of domestic fowl ( Gallus gallus ), contained potent inhibitors of trypsin and chymotrypsin. (2) These inhibitors extracted by TCA and heat treatment and partially purified by DEAE- and CM-cellulose chromatography were found to be proteins of low molecular weight.

Catecholamine synthesis in Ascaridia galli (Nematoda)
International Journal for Parasitology, 1988Abstract Smart D. 1988. Catecholamine synthesis in Ascaridia galli (Nematoda). International Journal for Parasitology18: 485–492. The distribution and synthesis of the catecholamines in female A. galli were examined using HPLC. Noradrenaline, adrenaline and the precursor dihydroxyphenylalanine were found to be concentrated in the gonads of the ...

Ascaridia galli (Nematoda): Development and survival in gnotobiotic chickens
Experimental Parasitology, 1973Infection and growth rates of the fowl nematode Ascaridia galli were compared in germ-free, conventional, and other gnotobiotic chickens. Uniform experimental infections induced in chickens at 7–12 days of age showed that significantly fewer (P < 0.01) worms established themselves in germ-free chickens than in chickens with conventional flora.

Immunity and tolerance of chickens to the roundworm, Ascaridia galli (Schrank)
Experimental Parasitology, 1955Abstract This study was undertaken in an attempt to clarify the concepts of immunity and tolerance with regard to Ascaridia galli and to determine whether the accepted theory of immunity is compatible with experimental observations on this nematode. The study used 348 White Rock chickens.

Statistical estimation of worm burdens (Ascaridia galli) in chickens
Experimental Parasitology, 1968Abstract Under controlled laboratory conditions a definite positive relationship was found between the number of Ascaridia galli in the host and the number of eggs in the feces. Prediction equations developed to estimate an unknown A. galli burden from a known fecal egg count (total, wet weight, dry weight) related: (1) total number of worms in ...

Co-expulsion of Ascaridia galli and Heterakis gallinarum by chickens
International Journal for Parasitology, 2018Worm expulsion is known to occur in mammalian hosts exposed to mono-species helminth infections, whilst this phenomenon is poorly described in avian hosts. Mono-species infections, however, are rather rare under natural circumstances. Therefore, we quantified the extent and duration of worm expulsion by chickens experimentally infected with both ...

Characterization of mitochondrial monoamine oxidase of Ascaridia galli
Journal of Helminthology, 1985ABSTRACT Oxidative deamination of various biogcnic monoamines by Ascaridia galli monoaminc 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.

Arrested development and the histotropic phase of Ascaridia galli in the chicken
International Journal for Parasitology, 1975Abstract Studies on 300 worm-free chickens infected with Ascaridia galli indicated that the histotropic phase is a normal part of the life cycle and that it involves both second- and third-stage larvae. The duration of the histotropic phase was dose-dependent.
