INTRODUCTION A TISSUE phase in the life cycle of the fowl nematode, Ascaridia galli, was announced by Ackert (1923) who found that the habitat or location of the larvae included the intestinal mucosa as well as the lumen. The next year Guberlet (1924) observed that chickens heavily infected with A. galli died from toxemia accompanied with intestinal irritation on the 10th to the 12th day following exposure to embryonated ova of this ascarid. Ackert and Herrick (1928) found that the most harmful period in the life cycle of this nematode was about 14 days after exposure of the host to embryonated ova. This finding was later corroborated by Ackert (1931) when he reported that irritation of the mucosal lining coincided with the tissue phase of the parasite which occurred between the 10th and 17th day subsequent to feeding embryonated ova to the host. More recently the importance of the various phases … |
