diets modulated haematological parameters, and histopathology revealed a reduction in
the extent of necrosis, degeneration and lesions in the liver and kidney. Other studies have
shown elevated immunological responses in non-challenged catfish;
Lb. acidophilus
fed
African catfish displayed elevated peripheral leukocyte levels, serum total protein levels and
serum total Ig levels (Al-Dohail
et al
. 2009), and
P. acidilactici
fed channel catfish displayed
elevated serum total protein levels, serum total Ig levels and complement activity (Shelby
et al
. 2007). Besides immunological responses and disease resistance, probiotic applications
have also been reported to improve catfish growth performance (Queiroz and Boyd 1998;
Bogut
et al
. 2000; El-Haroun
et al
. 2007; Al-Dohail
et al
. 2009) and catfish pond culture
production (Queiroz and Boyd 1998; El-Haroun
et al
. 2007).
Very little attention has been focused on the impacts of probiotic applications on the gut
microbiota in catfish studies. It has however been reported that dietary supplementation of
E.
faecium
could reduce wels catfish intestinal levels of
Staphylococcus
,
E. coli
, Enterobacte-
riaceae and
