Consequences of concurrent Ascaridia galli and Escherichia coli infections in chickens
Three experiments were carried out to examine the consequences of concurrent infections with Ascaridia galli and Escherichia coli in chickens raised for table egg production. Characteristic pathological lesions including airsacculitis, peritonitis and/or polyserositis were seen in all groups infected with E. coli. Furthermore, a trend for increased mortality rates was observed in groups infecte...
متن کاملThe effect of concurrent infections with Pasteurella multocida and Ascaridia galli on free range chickens.
Pasteurella multocida and Ascaridia galli are observed with high prevalences in free range chickens in Denmark, but the impact is unknown. A study was carried out to examine the interaction between A. galli and P. multocida in chickens and the impact on production. Five groups, each with 20 18-week-old Lohmann Brown chickens were infected. Group 1 was orally infected with 1000+/-50 embryonated ...
متن کاملSurvey of egg per gram (EPG) parasite ovum in pigeon
Clinical signs, para-clinical tests and gross lesion can be used for identification of parasite contamination. In most parasite contamination the clinical signs are not obvious. Thus, para-clinical tests and gross lesion play important roles in identifying parasite disease as all organs of animals such as skin, eyes, kidneys, liver and digestive tube can be affected by the parasites. Consequent...
متن کاملAscaridia galli infection of pullets and intestinal viscosity: consequences for nutrient retention and gut morphology.
1. Pullets were given a control diet or a diet supplemented with a non-starch-polysaccharide hydrolysing enzyme preparation (NSP-enzyme) from weeks 6 to 14 of age to induce differences in the viscosity of the small intestinal ingesta. Half of each feeding group (n = 25) was infected with 250 embryonated Ascaridia galli eggs at an age of 6 weeks. 2. At 14 weeks of age, before the pullets were sl...
متن کاملNematocidal Effects of Piperazine and the Extract of Acacia Oxyphylla Stem Bark on the Poultry Nematode, Ascaridia Galli
Acacia oxyphylla Graham ex Bentham (Mimosaceae) is a leguminous plant widely used in the traditional medicines of north-east Indian tribes. Among the Mizo tribes, the stem bark is commonly used as fish stupefying and deworming agents. This present experiment was aimed at evaluating the nematocidal effect, if any, upon Ascaridia galli Schrank (Nematoda), the intestinal roundworm of domestic fowl...
