Ascaridia galli: A Report of Erratic Migration

Italian Journal of Animal Science, 2005
This paper describes a case of an unusual recovery of adult Ascaridia galli in hen's egg. Several data are available on this occurrence but it appears to be the first case described in Italy.

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.

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 ...

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.

The Fate of Eggs and Larvae of Ascaridia galli in Earthworms

Avian Diseases, 1974
SUMMARY Earthworms were found to retain eggs and larvae of Ascaridia galli very briefly, and transmission can be attributed only to such eggs or larvae in transit in the digestive tract. Larvae of A. galli do not accumulate as do the larvae of Heterakis gallinarum, for the larvae of A. galli are voided within 48 hr of ingestion of the eggs. Since these

Monoamine oxidase in adult Ascaridia galli

Journal of Helminthology, 1983
AbstractMonoamine 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.

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.

Ascaridia galli: Trypsin and chymotrypsin inhibitors

Experimental Parasitology, 1976
Abstract (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, 1988
Abstract 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 ...

Immunity and tolerance of chickens to the roundworm, Ascaridia galli (Schrank)

Experimental Parasitology, 1955
Abstract 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.
