From Abstract (Click on the link in the Source below for a free, full copy of the paper.)


This study investigated the occurrence, serovar (serotype, variation or strain) and antimicrobial resistance of Salmonella species in shrimp samples from intensive and extensive farms located in three different provinces in the Mekong Delta, Vietnam.  Shrimp from 11 of the 48 farms all contained S. weltevreden, except for one farm yielding S. agona, with no difference in Salmonella occurrence between the two production systems.  S. weltevreden was susceptible to most antimicrobials tested, with a few strains being resistant to florfenicol, chloramphenicol, sulfamethoxazole or trimethoprim.  Future studies of the ecology of S. weltevreden should establish if this serovar might survive better and even multiply in warm-water shrimp farm environments compared to other Salmonella serovars.
