Natural Transmission of Avian-Lymphomatosis

The Role of the Infected Egg in the Transmission of Visceral Lymphomatosis

“…2 where chicks of isolated stock, when brooded with chicks of infected stock, developed a high incidence of V.L. Similar results have been reported by Waters (1945), Waters and Bywaters (1949).…”

Egg Transmission of Avian Lymphomatosis

“…The low percentage of visceral lymphomatosis mortality in isolated groups of inbred line 15 chickens has been substantiated in many previous experiments (Waters and Prickett, 1944;Waters, 1945Waters, ,1947Waters and Bywaters, 1949). The low percentage of visceral lymphomatosis mortality in isolated groups of inbred line 15 chickens has been substantiated in many previous experiments (Waters and Prickett, 1944;Waters, 1945Waters, ,1947Waters and Bywaters, 1949).…”

“…Epiornithological observations on the spread of lymphomatosis indicated to some workers that the disease may have been introduced into flocks by the purchase of hatching eggs from infected flocks (Doyle, 1929;Emoto and Miyamoto, 1930;Marginson and McGaughey, suggested egg transmission (Waters, 1945). In this flock only eggs were introduced into previously unused quarters and cases of lymphomatosis were found during the second and subsequent months after the chicks hatched.…”

Histological and histochemical studies on the distribution of few enzymes in the neoplastic liver of <i>Uroloncha malabarica</i> (Linnaeus)

“…* Much work was conducted to know the reason for its occurrence and control. Transmission occurred by eggs, as indicated by Waters [1945], 1954], while Cole and Halt [1951] came to an opposite conclusion. It has been recognized by poultry pathologists that lymphocytomas may be much more common in some flocks than in others.…”
