Therefore, specific anthelmintic efficacy and toxicity of a compound should be determined before it is widely used* The purpose of this investigation was to test -Uie relative effectiveness and toxicity of various compounds and combinations of compounds against Ascaridia galli, the large roundworm of ohiokens. This parasite is respon- sible for considerable "hidden" loss in chicken flocks, especially when it is present in the tissue phase of its life cycle* Fiperasine citrate was used at various levels and in combination with nicotine, phenothiasine, and a piperasine derivative CL 16147* Vermisym, a compound not related to piperasine was also tested against A.

  • New Records of Ascaridia Platyceri (Nematoda) in Parrots (Psi Aciformes)
    Vet. Med. – Czech, 49, 2004 (7): 237–241 Original Paper New records of Ascaridia platyceri (Nematoda) in parrots (Psi�aciformes) V. K�������1, V. B����2, I. L������1 1Department of Biology and Wildlife Diseases, University of Veterinary and Pharmaceutical Sciences Brno, Czech Republic 2Institute of Vertebrate Biology, Academy of Sciences of the Czech Republic, Brno, Czech Republic ABSTRACT: The aim of the study was to determine the range of species of ascarids in parrots in the Czech Repub- lic. Ascarids were found during post-mortem parasitological examination of 38 psi�aciform birds belonging to 15 different species. All ascarids found were determined as Ascaridia platyceri. Nine bird species were determined as new hosts of this parasite. A. platyceri is a typical ascarid for parrots of Australian origin. The fact that this parasite was found in bird species of African origin demonstrated a possibility of spread of A. platyceri to hosts of different zoogeographical origin. A. platyceri was described in detail from the host Melopsi�acus undulatus and differentiated from other ascarids on the basis of morphological and quantitative traits. The most important differentiating traits included the presence of interlabia in both sexes. In males, the traits important for species identification included the number and location of caudal papillae (a total of 9 to 10 pairs), relatively short spicula and absence of cuticular alae on the spicula, while females featured a conical shape of the tail.

The birds were caught next to grain storage warehouses and were necropsied. A total of 790 parasites comprising one nematode species and one cestode genus were recovered from 110 pigeons, thus yielding an overall prevalence of 41.5%, mean intensity of infection of 7.2 ± 1.6 (range 1-144) and discrepancy index of 0.855. Only 15 pigeons (5.7%) presented mixed infection. The helminths isolated from the birds were Ascaridia columbae (Ascaridiidae) and Raillietina sp. (Davaineidae). The birds’ weights differed according to sex but this did not influence the intensity of infection. The overall prevalence and intensity of infection did not differ between the sexes, but the prevalence was higher among the birds from Tatuí (47.8%).

C) FAO 1998 PREFACE Poultry products are one of the most important protein sources for man throughout the world and the poultry industry, particularly the commercial production systems have experienced a continuing growth during the last 20-30 years. The traditional extensive rural scavenging systems have not, however seen the same growth and are faced with serious management, nutritional and disease constraints. These include a number of parasites which are widely distributed in developing countries and contributing significantly to the low productivity of backyard flocks.

  • A Parasite of Red Grouse (Lagopus Lagopus Scoticus)
    THE ECOLOGY AND PATHOLOGY OF TRICHOSTRONGYLUS TENUIS (NEMATODA), A PARASITE OF RED GROUSE (LAGOPUS LAGOPUS SCOTICUS) A thesis submitted to the University of Leeds in fulfilment for the requirements for the degree of Doctor of Philosophy By HAROLD WATSON (B.Sc. University of Newcastle-upon-Tyne) Department of Pure and Applied Biology, The University of Leeds FEBRUARY 198* The red grouse, Lagopus lagopus scoticus I ABSTRACT Trichostrongylus tenuis is a nematode that lives in the caeca of wild red grouse. It causes disease in red grouse and can cause fluctuations in grouse pop ulations. The aim of the work described in this thesis was to study aspects of the ecology of the infective-stage larvae of T.tenuis, and also certain aspects of the pathology and immunology of red grouse and chickens infected with this nematode. The survival of the infective-stage larvae of T.tenuis was found to decrease as temperature increased, at temperatures between 0-30 C? and larvae were susceptible to freezing and desiccation. The lipid reserves of the infective-stage larvae declined as temperature increased and this decline was correlated to a decline in infectivity in the domestic chicken. The occurrence of infective-stage larvae on heather tips at caecal dropping sites was monitored on a moor; most larvae were found during the summer months but very few larvae were recovered in the winter. The number of larvae recovered from the heather showed a good correlation with the actual worm burdens recorded in young grouse when related to food intake. Examination of the heather leaflets by scanning electron microscopy showed that each leaflet consists of a leaf roll and the infective-stage larvae of T.tenuis migrate into the humid microenvironment' provided by these leaf rolls.

This study investigated the gene expression profiles in Chickens chickens from two different provinces of South Africa naturally exposed to A. galli infestations and tested either Transcriptomes positive or negative for the parasite. The study further investigated gene expression profiles of the A. galli Adaptive mechanisms infected duodenum, jejunum and ileum tissues of the small intestines. The A. galli positive intestines displayed hypertrophy of the intestinal villi with accumulation of inflammatory cells and necrosis of the crypts of Lieberkühn glands, lesions that were absent in the uninfected intestines. Total RNA isolated from small intestines of infected and non-infected intestines was sequenced using Illumina HiSeq technology to generate up to 23,856,130 reads.

  • Blackhead Disease in Poultry Cecal Worms Carry the Protozoan That Causes This Disease
    Integrated Pest Management Blackhead Disease in Poultry Cecal worms carry the protozoan that causes this disease By Dr. Mike Catangui, Ph.D., Entomologist/Parasitologist Manager, MWI Animal Health Technical Services In one of the most unique forms of disease transmissions known to biology, the cecal worm (Heterakis gallinarum) and the protozoan (Histomonas meleagridis) have been interacting with birds (mainly turkeys and broiler breeders) to perpetuate a serious disease called Blackhead (histomoniasis) in poultry. Also involved are earthworms and house flies that can transmit infected cecal worms to the host birds. Histomoniasis eventually results in fatal injuries to the liver of affected turkeys and chickens; the disease is also called enterohepatitis. Importance Blackhead disease of turkey was first documented in [Fig. 1] are parasites of turkeys, chickens and other the United States about 125 years ago in Rhode Island birds; Histomonas meleagridis probably just started as a (Cushman, 1893). It has since become a serious limiting parasite of cecal worms before it evolved into a parasite factor of poultry production in the U.S.; potential mortalities of turkey and other birds. in infected flocks can approach 100 percent in turkeys and 2.

Box: 307, Jimma, Ethiopia Mihretu Ayele Department of animal health, Alage Agricultural TVET College, Ministry of Agriculture and Natural Resource, Ethiopia Abstract Parasitic diseases are among the major constraints of poultry production. The common internal parasitic infections occur in poultry include gastrointestinal helminthes (cestodes, nematodes) and Eimmeria species. Nematodes belong to the phylum Nemathelminthes, class Nematoda; whereas Tapeworms belong to the phylum Platyhelminthes, class Cestoda. Nematodes are the most common and most important helminth species and more than 50 species have been described in poultry; the majority of which cause pathological damage to the host.The life cycle of gastrointestinal nematodes of poultry may be direct or indirect but Cestodes have a typical indirect life cycle with one intermediate host. The life cycle of Eimmeria species starts with the ingestion of mature oocysts; and
