Transient or Permanent Inhabitants: Cultured Internal Microbiota of Cichlidogyrus thurstonae and Scutogyrus longicornis (Monogenea: Ancyrocephalidae) from Oreochromis sp.

Monogeneans, a class of parasitic platyhelminthes, are usually found on the surface fish. When it feeds its host, harbours bacteria, which can survive in gut. Occasionally, monogeneans may cause damages fish tissue while feeding and allow secondary infection. The present study aimed to isolate identify culturable bacteria obtained within gill monogeneans, Cichlidogyrus thurstonaeand Scutogyrus longicornis, tilapia fish, Oreochromis sp. based 16S ribosomal RNA gene sequencing. Monogeneans were isolated from filaments disinfected using 70% ethanol before squashed aseptically Luria Bertani (LB) agar internal microbiota. A total five species, namely Burkholderia sp., Enterobacter hormaechei, Ochrobactrum intermedium Pantoea C. thurstonae, whilst eight contaminans, dispersa, Sphingomonas yabuuchiae, Rhizobium pusense, O. intermedium, Acinetobacter bereziniae, Escherichia hermannii, Staphylococcus saprophyticus, S. longicornis B.
