such as Pasteurella haemolityca which is one of
the most common bacterial pathogen involved in veterinary
diseases such as pneumonic pasteurellosis in sheep all over the
world (30). It is responsible of much mortality in hatchery
environments, in animal farming industry and it considered as
an aetiological agent of fish pasteurellosis (13, 28, 25). For
these reasons, it is necessary to study the bacterial interaction
with crustaceans in order to distinguish between pathogens and
potential probiotic candidate, because it is found that bacteria
had a beneficial effect such as providing nutritional elements
like vitamins, essential amino acid, fatty acids and enzymes
(10, 36). Other microbiological studies have demonstrated that Bacillus sp. and Aeromonas hydrophila can protect Artemia
against pathogens such us Vibrio proteolyticus and Vibrio
campbelli (19).
