Changes of iron content in eels (Anguilla japonica) infected with atypical Aeromonas salmonicida

Abstract

1. Hb, MCHC, Na, Ca, Mg and Cu in plasma decreased with atypical Aeromonas salmonicida infection. Whilst plasma K and NPN increased.

2. Plasma Fe decreased markedly with infection. No statistically significant change in UIBC was found, though moribund eels showed slightly lower values compared to that of the control. The rate of decrease in TIBC is similar to that in most elements in plasma.

3. Fe content in most tissues decreased with infection. It increased in the gills and head muscle (infection site). No significant change was found in the intestine.

4. Water content in various tissues increased with infection.
