General Background: Fish, particularly Cyprinus carpio, are vital to global food security and aquaculture economies due to their high protein content and widespread availability. Specific Background: However, these fish can harbor a range of bacterial pathogens, especially in environments like the Shatt al-Arab River, where pollution and aquaculture stressors may exacerbate microbial contamination. Knowledge Gap: There is limited localized data on the bacterial flora present in healthy common carp from this river system, particularly regarding potential human pathogens. Aims: This study aimed to isolate and identify bacterial species present in the skin, liver, and intestines of apparently healthy C. carpio from the Shatt al-Arab River. Results: A total of 122 bacterial isolates were identified using phenotypic methods and Vitek II, with Aeromonas hydrophila (13.93%), Vibrio spp. (12.29%), Staphylococcus aureus (12.29%), and Escherichia coli (11.47%) among the most prevalent. Novelty: The detection of high bacterial incidence in healthy fish, particularly fecal indicators, suggests significant environmental contamination and unrecognized risks to consumers. Implications: These findings underscore the need for improved water quality monitoring and hygienic handling practices in fisheries to prevent potential zoonotic infections and ensure public health safety.
Highlight :
-
The study identifies a high prevalence (85%) of bacteria in healthy Cyprinus carpio, highlighting public health risks from contaminated fish.
-
Dominant bacteria included Aeromonas spp., Vibrio spp., E. coli, and Staphylococcus aureus, indicating possible fecal contamination.
-
The intestine was the most bacteria-rich organ, suggesting it as a critical site for monitoring bacterial colonization in aquatic species.
