Abstract: The present study was carried out to determine the seasonal occurrence and distribution of microbial diversity of pathogenic bacteria population present in mitten crab
Eriocheir sinensis (H. Milne Edwards, 1853). Samples of crabs were collected during 2017, from the intertidal zones of Khor Al-Zubair canal in two seasons by hand under stones close to collection site. A total of 24 bacterial isolates consisting five different bacterial strains such as
Pseudomonas aeruginosa, Escherichia coli, Aeromonas sp., Klebsiella pneumoniae and
Bacillus subtilis were isolated from gills, shells and muscle tissues of mitten crab
Eriocheir sinensis. Microbial species were characterized based on morphological and biochemical tests. The percentage composition of each bacterial species was recorded in different tissues of crab samples,
E. coli (35%) and
Pseudomonas aeruginosa (32%) are dominant among other species in crab shells and gills, respectively.
Klebsiella pneumoniae (27%) and
Bacillus subtilis (18%) are dominant among other species. In crab muscles,
Bacillus subtilis (33%) and
E. coli (28%) is dominant among other species. Shells and gills of crab samples showed higher number of bacterial species than muscles tissues. The results of this study clearly indicate that edible crabs are contaminated with coliforms and other pathogenic microorganisms.
