In-vitro observation of Streptococcs agalactiae infection in fish by histology method

Abstract

It is very difficult to control Streptococcosis, since it always appear when the fishes are stressed by water quality. Moreover the bacterium is ubiquitous. This project is aimed at providing basic information that will help any further studies related to this infection. The focus of this study is to determine the exact time when the gills tissue of Tilapia are completely infected by the bacteria, Streptococcus agalactiae and also the histopathology effect towards the gills through histology processing. The sampling location is located at Kawasan Pentemakan lkan Air Tawar Berkelompok at Pantai Ali, Kuala Berang, Hulu Terengganu, Terengganu. The experiments covered the aspects of bacteria preparation, gills preparation and histological processing.
