| Summary: | Vibriosis in shrimp farms poses potential risks to the industry’s sustainability and the
consumers’ health. Little is known about the dynamics and variation of Vibrio spp—population
in shrimp production in Sarawak, Malaysia. The apparent prevalence of three Vibrio species,
V. parahaemolyticus, V. cholerae, and V. alginolyticus, were investigated in water (n=12),
sediment (n=12), shrimp (n=12), and effluent (n=12) samples collected from two ponds in a
coastal shrimp farm during one production cycle. Multiplex-PCR using specific primer sets
showed the presence of the three Vibrio species. Based on the results, V. parahaemolyticus was
the most prevalent in all four samples, with a contamination rate of 97.92% (95% CI: 89. 10 to
99.89%), while V. cholerae and V. alginolyticus had a contamination rate of 47.92% (95% CI:
34.37 to 61.67%) and 25.0% (95% CI: 14.92 to 38.78%), respectively. High Vibrio load in the
shrimp farm is due to favourable environmental factors, such as optimal temperatures, salinity,
and pH ranges for the growth of these species. The study’s findings offer important preliminary
insights into the prevalence and distribution of these pathogenic Vibrio spp., within a shrimp
farm in Kuching, Sarawak. This study serves
as a potential model for monitoring Vibrio
spp. prevalence in other shrimp farms across
Sarawak, thereby addressing the scarcity of
data on prevalence in the region |
