title: Induced systemic candidiasis in young broiler chickens.
abstract: Systemic candidiasis was induced in broiler chickens 14 days old by intravenous injection of a suspension of viable Candida albicans cells. Injection resulted in decreased body weight, moderate mortality, swollen and reddened livers and kidneys, pancreatitis, and disturbances of the nervous system. Three types of neutral disturbances were observed: 1) extreme opisthotonus with spasmodic tremors; 2) extreme torticollis with cranial rotation of 270 degrees: and 3) extreme torticolis which resulted in the head being drawn in a medial-ventral direction. None to 50% of the inoculated birds exhibited these neural disturbances, depending on the isolant of C. albicans used. Microbiological examination of internal organs and blood revealed that C. albicans localized in the meninges of the brain. There was also a significant isolant-related effect of C. albicans on the growth rate of the inoculated birds. These easily quantitated differential effects of various isolants of C. albicans offer the prospect of correlating biochemical characteristics with virulence and obtaining information about the mechanism of pathogenicity of this microorganism.
