Clinical, Microbiological, and Hematological Assessment of Vibrio Infection in Flathead Grey Mullet (Mugil cephalus) Near the Port Benghazi, Libya

Year: 2025

Type: article

Abstract: The present study aimed to address the impact of Vibrio bacteria on the health status of Mugil Cephalus inhabiting the coastal area of Benghazi port. A total of 20 samples of (M. Cephalus) were collected at random from the Benghazi Harbour throughout the period from March 2025 to Augest 2025, All the specimen from the fish were examined outwardly and inwardly and lesions were registered. Bacterial isolation from the liver and kidney was done using the appropriate culture media. The infection rate was 30% . The external lesions during the spring and summer seasons were hemorrhages at the base of the pectoral fin and around the operculum, congestion of caudal and anal fins. While internal lesions were splenomegaly, congested liver, kidney, and swim bladder. Bacteriological identification was confirmed based on the cultural characteristics and biochemical activities of isolates, On adjusted TCBS medium the recovered colonies showed as circular yellow or green colonies ranging characteristic of Vibrio spp. , In regards to the hematological parameters associated with diseased and apparently healthy Mugil Cephalus. The total protein, and globulin were lower in diseased than apparently healthy Mugil Cephalus fish, Data were statistically analyzed using T-test to compare healthy and infected fish, and differences were considered significant at (p<0.05).
