Hematological indices such as immature erythrocyte percentage (%), hematocrit and hemoglobin concentrations, glucose, plasma ammonia and osmolality have been used as markers to evaluate fish health under various toxic exposures [11,12,31,34-40].
Valenzuela A, Silva V, Tarifeno E, Klempau A (2005) Effect of acute hypoxia in trout (Oncorhynchus mykiss) on immature erythrocyte release and production of oxidative radicals.
We also found rounded immature erythrocytes (Figures 1A-1D) similar to basophilic erythroblasts (rubricytes) that had a very thin basophilic cytoplasm forming a small ring around the nucleus, which was generally round (Figure 1A).
Some immature erythrocytes were found in the rhea blood smears.
Another factor that is an increase in immature erythrocytes (smaller in size, rounded in shape, grayish-blue in color and contain less hemoglobin) was observed in the infected blood during the infection of T.
