Occurrence and anti-toxin powerlessness pattern of Vibrio species disconnected from ocean nourishments sold in Port-Harcourt, Nigeria

Abstract

Most Vibrio infections are associated with the consumption of raw or undercooked sea foods or
exposure of wounds to warm seawater. In this study, 63 samples of a variety of sea foods viz: shrimps,
periwinkle, prawn, crayfish collected from two major household markets in Port-Harcourt were cultivated
using standard bacteriological method on Thiosulphate Citrate Bile Sucrose (TCBS) agar. A total of 63
Vibrios belonging to seven different species were isolated with Vibrio fluvialis recorded as the highest
percentage frequency occurrence and the most predominant species, 30 (47.6%), followed by Vibrio
paraheamolyticus with 19 (30.2%), Vibrio vulnificus with 4 (6.34%), Vibrio metschnikovi with 4 (6.34%),
Photobacterium spp. with 3 (4.76%), Vibrio cholerae with 2 (3.17%) and the least was Vibrio mimicus with
1 (1.60%). Statistically, there was a significant different (P< 0.05) in prawn sold in Mile 1 market as
compared to prawn sold in Mile 3 markets. These isolates were subjected to their susceptibility patterns
using agar diffusion method, which recorded susceptible to most antibiotics used. The presence of these
pathogenic strains of Vibrios in commonly consumed sea foods is of public concern.
