Ciudad Universitaria, Alcaldía Coyoacán, C. 10, 2023, es una revista que publica en modalidad continua editada por la Universidad Nacional Autónoma de México, Av. capillare significantly decreases the sludge worm’s bacterial charge, by reducing the number of species from 15 to 4 and from 2 x 109 to 3 x 105 cfu/mL, in two weeks of treatment. A unilateral variance analysis was applied.

Every seven days and during five weeks, a qualitative and quantitative analysis of the bacterial charge of each worm groups was carried out, this was identified according to the Merck Manual and the API-20E.

capillare alga placed freely in the aquarium, and the other one contained within a mesh so it would not have contact with the worm in two more aquariums, 2 g of two antibiotics for aquaculture use were mixed,one with kanamicin added, another with ampicillin, and a third with only water as control. A 100 g of Tubifex were left free in five aquariums, all in similar conditions of: water temperature, aeration and water volume, four of these were experimental, one with O. capillare alga constitutes a good source to reduce the bacterial charge of the Tubifex worm. The present study has the objective to prove that O. Oedogonium capillare alga possesses bactericide capacity against different bacterial genera.

Nevertheless, in controlled culture conditions 'clean' population can be obtained. coli, also, in an obliged Myxobollus cerebralis host. It becomes a direct vector of bacteria such as Salmonella, Shiguella and E. The sludge worm Tubifex sp is a good live food for aquatic species due to its high nutrimental content, short reproduction period, its broad range of habitats, and its fertility and reproductive capability in wide temperature range (0.5✬-30✬).
