| Summary: | Introduction: Lactococcus garvieae is the causative agent of
lactococosis in fish which is transmittable to human in the case of contact or
consumption of infected fish. The bacteria has been highly prevalent in fish
farms.
Materials and methods: In this study, frequency and
antimicrobial resistance of L. garvieae was studied in rainbow trout
fish farms in Chaharmahal va Bakhtiari Province. A total of 100 fish from 33
fish farms were collected in summer 2013 and were transmitted to the laboratory
in appropriate conditions. The isolates were identified using biochemical tests
and PCR.
Results: The results indicated that fish from 23 out of 33 studied farms were
infected with L. garvieae and 49 isolates were collected from the fish.
The results also represented multi drug resistance of all isolates to common
antibiotics. Minimum and maximum resistance was 30.7 and 65.4% for gentamicin
and enrofloxacin, respectively.
Discussion and conclusion: Infection of fish in more than 76 percent of the studied fish farms
and high drug resistance of Lactococcus is a serious danger for aquaculture and
for public health. Moreover, ability to infect humans and countless problems
due to transmission of antimicrobial resistance to other bacteria reduplicates
the importance of controlling the disease and surveillance on using
antimicrobials in fish farms. |
