Establishment of Ascaridia galli in betamethasone-treated chickens

Veterinary Parasitology, 1987
Twenty-five day-old White Leghorn chickens were each infected orally with 500 (Group I), 1000 (Group II) and 2000 (Group III) infective eggs of Ascaridia galli and were killed 30 days after the infection. A high percentage of the infecting dose (6.5%) established as adult worms in the intestine of chickens receiving the lowest level of primary ...

Ascaridia galli isolates with ITS1-5.8rRNA-ITS2 fragment homologous to Ascaridia columbae

Acta Parasitologica, 2018
Abstract 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.

Genetic resistance to Ascaridia galli infections in chickens

Veterinary Parasitology, 2001
Ascaridiosis is still a cause of economic losses in modern poultry production systems. Improving genetic resistance to this disease provides an attractive alternative for free-range organic poultry producers and will eventually reduce the extensive use of anthelmintic drugs.

Nippostrongylus brasiliensis and Ascaridia galli: Characterization of peroxisomes

Experimental Parasitology, 1990
A 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.

Statistical estimation of worm burdens (Ascaridia galli) in chickens

Experimental Parasitology, 1968
Abstract 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 ...

Ascaridia galli (Nematoda): Development and survival in gnotobiotic chickens

Experimental Parasitology, 1973
Infection 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.

Metabolism of amino acids in Ascaridia galli: decarboxylation reactions

International Journal for Parasitology, 1983
Abstract Production of 14CO2 from 12 carbon-labelled amino acids by Ascaridia galli was studied. Appreciable amounts of CO2 were evolved from alanine, aspartate, glutamate, serine, leucine and valine by intestines, ovaries, cuticle and intact worms, in that order, but not from lysine, proline and tyrosine. Maximum CO2 produced by whole worms was from

Characterization of mitochondrial monoamine oxidase of Ascaridia galli

Journal of Helminthology, 1985
ABSTRACT 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.

Cyclic AMP-dependent and independent protein kinases in Ascaridia galli

Molecular and Biochemical Parasitology, 1984
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 ...
