Diversidad bacteriana aislable del intestino del camarón cultivable (agua salada y agua dulce) como potencial fuente de MO probióticos

Abstract

Abstract: Shrimp farming is a source of economic resources worldwide, however, the rate of shrimp production is affected by diseases caused by fungi, bacteria and viruses. The control of pathogenic microorganisms is directed exclusively to the application of antibiotics or other chemical compounds. This research allowed to isolate and biochemically characterize bacterial strains of healthy shrimp grown in fresh water (Huaquillas, La Aguada sector) and salt water (Jambelí Archipelago, Las Huacas sector). The specimens found in the future after evaluation in situ, will be determined as feasible for inclusion as probiotic products that strengthen the immune system of shrimp and improve their development. The results indicated a wide diversity of bacterial species for the genera Citrobacter, Escherichia, Klebsiella, Salmonella. The number of bacteria did not signal significant changes (p-value >0.05) between fresh and salted water. Species such as Pseudomona aeruginosa and genera such as Pseudomona, Enterobacter are promising to apply in future trials as probiotics in shrimp farming.
