Abstract

The present study purposed for the identification of the effects of histopathology of natural infection of the ciliated protozoa, Ichthyophthirius multifiliis on the wild snakehead murrel Channa striata gills, collected from Surabaya River in Surabaya, East Java Province, Indonesia. This is because I. multifiliis is a ciliated protozoan that often infects and causes serious problems in freshwater fish, including snakehead fish. On the one hand, histopathology devotes a well mode for discover the irritants and pathogens effects in various organs including gills which are vital organs of fish. Live fish were immediately transferred to the Parasitology laboratory and examined within 24 h. The gill smears were tested for the parasite I. multifiliis and ciliates were identified microscopically sans staining. The second step was performed a histopathological examination of the gills. We found a white spot with different diameters on the gill filaments, and the colour changed. The study of histopathology showed heavy damage to the primary lamellae and secondary lamellae, including: increased cell size (hypertrophy) and cell number (hyperplasia), fusion of secondary lamellae and blood congestion from the base of the primary lamella. We concluded that the changes of histopathological became an indicator of gill damage caused by I. multifiliis will ultimately conduct to reduced surface area for effective breathing, then cause hypoxia, lethargy and death.
