The Etiology of Infectious Sinusitis of Turkeys

Characterization of Avian Mycoplasma

“…Mice were reported to be refractory by Van Roekel et al (172) Jerstad and Hamilton (103), Chute and Cole (31), Group/ and Winn (82), and Yamamoto (179). Van Herick and Eaton (168) reported negative results in mice, hamsters, rats and guinea pigs.…”

The Characteristics of an Agent Morphologically Resembling the Chlamydozoaceae and Causing Sinusitis in Turkeys

“…That the agent described in this communication is not the only agent capable of producing sinusitis in turkeys is shown by the fact that clinical sinusitis has also been produced in turkeys by the inoculation of Hemophilus gallinarium (Beach and Schalm, 1936). In addition, agents capable of producing sinusitis in turkeys have recently been propagated in the allantoic sac of chicken embryos by Jerstad and Hamilton (1948) and in 11-day embryos by Hitchner (1948). However, the relationship of the latter agents to each other and to the agent described here is not known.…”
