Abstract:
Objective —To determine the prevalence of Streptococcus iniae in tilapia ( Oreochromis spp),
hybrid striped bass ( Morone chrysops × M saxatilis ),
and channel catfish ( Ictalurus punctatus ) on commercial
fish farms in the United States. Animals —1,543 fish (970 tilapia, 415 hybrid striped
bass, and 158 channel catfish). Procedures —The dry-swab technique was used for
collection of specimens for streptococcal isolation. Specimens were shipped by overnight delivery and
processed by use of standard bacteriologic techniques. Results — Streptococcus iniae was not isolated from
market-size channel catfish. Prevalence in tilapia and hybrid striped bass was 37 of 970 (3.81%) and 30 of
415 (7.23%), respectively. Prevalence by farm ranged from 0.0 to 27.4% for tilapia and 0.0 to 21.6% for
hybrid striped bass. In tilapia, prevalence was lowest in market-size and nursery fish (4 of 239 [1.67%] and 3 of 339 [0.88%], respectively), with an increase in prevalence for fish in the grow-out stage (30 of 337
[7.96%] ). For hybrid striped bass, prevalence was
lowest in nursery and market-size fish (3 of 96 [3.12%] and 1 of 47 [2.12%] , respectively) and highest
in fish in the grow-out stage (26 of 272 [9.56%] ).
Prevalence in market-size tilapia and hybrid striped bass was 5 of 286 (1.75%). Conclusions and Clinical Relevance —Results of
this study do not support the contention that S iniae is a serious public health threat associated with commercially
raised fish; rather, it represents a limited risk for older or immunocompromised people who incur
puncture wounds while handling and preparing fish. ( Am J Vet Res 2001;62:174–177)
