Abstract
This current study was applied for investigating the presence of Pseudomonas species bacteria from cultured marine shrimp (Litopenaeus vannamei) collected from the Suez Governorate randomly and seasonally during the period from March 2020 to November 2020. Our results revealed that the suspected isolated bacteria were identified as Pseudomonas fluorescence depending on both morphological and biochemical characteristics using traditional as well as API20E commercial tests. The clinical signs that appeared on the infected shrimp were melanization on the body surface and darkening of appendage tips, inflamed tail, rostrum deformity, darkened gills, and paleness of hepatopancreas. The total prevalence of Pseudomonas infection was 17.33%, while the highest seasonal prevalence was recorded in the summer season (20%) followed by the autumn season (18%) and the lowest percent was the spring season (14%). The histopathological examination revealed the presence of hemocyte filtration, sloughing hepatopancreas cells, necrotic inflammation, hemocyte plug, broken musculature, and epithelial edema. We concluded that higher temperature is the predisposing factor for Pseudomonas infection.
