After 19 weeks on a mash diet nine of the 10 birds exhibited from two to 19 oral lesions. The majority of these lesions involved the total erosion of the buccal epidermis giving a total area of exposed dermis of 0.6 to 94.5 mm(2). This was accompanied by a significant reduction in the numbers of heterophils, monocytes and eosinophils. Birds with lesions also had significantly reduced concentrat...

To measure stress in caged hens, differential counts of their wing vein blood were used to determine heterophil/lymphocyte (H/L) ratios and total white blood cell counts (TWBC). The H/L values of 18-wk samples from conventionally caged hens (CC) were not statistically different from hens raised in aviaries (AV) when calculated by either of 2 methods (H/L 1 and H/L 2). However, there was a high ...

This study evaluated the physiological responses of subadult yellow-spotted Amazon river turtle, Podocnemis unifilis, to incremental crude protein levels (29%, 32%, 35%, and 39% CP) as extruded commercial feeds. The hematological plasma biochemical parameters P. unifilis were analyzed at 60, 120, 180 days feeding trial. increase in total thrombocyte, leukocyte, lymphocyte, heterophil, eosinophi...

Parasites have the potential to be important forces driving the evolution of honest signals (e.g. visual communication in the context of sexual selection) because they can affect the expression of colours in the host. Birds are affected by a variety of parasite taxa, but despite their acknowledged importance in epidemics, the role of bacteria in sexual selection in birds has been poorly investi...

The zebrafish is a useful model organism for developmental and genetic studies. The morphology and function of zebrafish myeloid cells were characterized. Adult zebrafish contain 2 distinct granulocytes, a heterophil and a rarer eosinophil, both of which circulate and are generated in the kidney, the adult hematopoietic organ. Heterophils show strong histochemical myeloperoxidasic activity, alt...

On May 6, 1949, a preliminary account was given before the Swedish Society for Internal Medicine of a special method for the sheep-cell agglutination test based on experiments made by the authors (Svartz and Schlossmann, 1949). A similar account was presented to the Seventh International Congress on Rheumatic Diseases, New York, 1949. First we must emphasize the fact that all human sera contain...

the objective of the study was to compare the effects of antibiotic virginiamycin, probiotic protexin® and plantago major l. (plantain) on performance, serum metabolites, immune response, and the ileal microbial population of broilers. the experiment was carried out with a total of 200 day-old male ross 308 broiler chickens in a completely randomized design. chickens were allocated to five grou...
