Abstract or Summary
  • Staphylococcal tenosynovitis and osteomyelitis are world-wide problems of broilers and broiler breeders caused by staphylococci. Pathogenesis of the disease is ill defined. Avian heterophils are analogous to mammalian neutrophils but the granules appear to be different. The first chemotactic study was done on heterophils from chickens having natural staphylococcal infection brought from a commercial broiler flock and on the heterophils obtained from healthy 6-8 weeks old chickens brought from a local hatchery as one day old chicks. In the second study, a chemotactic study was done with three different staphylococci on heterophils obtained from healthy 6-8 weeks old chickens brought from a local hatchery as one day old chicks. Results for the first study showed a decreased chemotactic response in the heterophils of chickens naturally infected with staphylococcus compared to healthy chicken heterophils in response to minimum essential medium, pooled normal chicken serum and E. coli endotoxin with normal chicken serum used as chemoattractants. Second study results showed that pathogenic capsule type 5 and type 8 Staphylococcus aureus isolates both induced chemotaxis in heterophils from healthy chickens to a significantly greater degree than did a non-pathogenic Staphylococcus xylosus. The Staphylococcus aureus isolate with capsule type 5 induced heterophil chemotaxis more than the capsule type 8 isolate.
