A Pasteurella or Pasteurella-Like Organism as the Cause of an Infectious Sinusitis of Turkeys

The Etiology of Infectious Sinusitis of Turkeys

“…This supports Hart's (1940) opinion that the disease appears to be a virus. Delaplane's (1946) statement that a virus-like agent can be grown on chick embryos is likewise supported by the findings reported in this paper. CONCLUSIONS 1.…”

“…Culture of the harvested embryonic fluids in experiments A, B and C was accomplished by allowing a portion of the fluid to run over an enriched nutrient agar slant and collect at the bottom of the tube. Blood cells were usually present in this fluid and this was judged to give a favorable medium for growth of H. gallinarum in particular (Delaplane, Erwin and Stuart, 1934).…”

“…In a subsequent paper Lee (1942b) wrote that in many outbreaks on organism having all the characteristics of H. gallinarum has been isolated. Delaplane, Erwin and Stuart (1934) on the other hand, reported in their original studies on H. gallinarum that turkeys, pigeons, sparrows and a crow were not susceptible to infectious coryza, but that the disease was found in natural outbreaks in pheasants. Beaudette (1946) stated that at least two types of organisms can be isolated from cases of sinusitis in turkeys.…”

“…One case was found in which the organism appeared to be that of fowl cholera, but failed to produce indol. Delaplane (1944) isolated a pasteurella or pasteurella-like organism which caused a sinusitis of an infectious nature, but he stated that it may not be the cause of all cases of sinusitis in turkeys. This organism was isolated from chickens inoculated intranasally with exudate from turkeys.…”

“…Madsen (1938) was unable to reproduce the disease by use of a Berkfeld filtrate of sinus exudate. Delaplane (1946) indicated that he has grown a virus-like agent on chick embryos that was capable of inciting sinusitis in each of five successive egg passages.…”
