Bacterial Shrimp Disease in Iraqi Marine Waters

Abstract

A sample of 116 shrimps Metapenaeus affinis (H. Milne-Edwards, 1837) were collected from local fish markets in Basrah Province, Southern Iraq. Height, weight, and pathological signs of the shrimps were recorded. Both morphological and biochemical examination by VITEK identification system were undertaken. Pathological infections were seen on the cuticle of abdominal segments in addition to a severe infection in uropod (tail segment), rostrum and pleopods (walking legs). Results of biochemical identification showed the presence of Aeromonas sobria and A. salmonicida from the infected organs and this study is considered as the first record of this bacterial infection in shrimps in Iraq.
