NCBI PD link for serovar Weltevreden: https://www.ncbi.nlm.nih.gov/pathogens/isolates/#(taxgroup_name:%22Salmonella%20enterica%22)%20AND%20computed_types:(%22serotype=Weltevreden%22)

Genetic characteristics: Serovar Weltevreden has been found to be monophyletic. A clonal group of serovar Weltevreden isolated in farmed shrimp from Vietnam’s Mekong Delta showed susceptibility to most tested antimicrobials, though some isolates exhibited resistance to florfenicol, chloramphenicol, sulfamethoxazole, or trimethoprim. However, all serovar Weltevreden isolates (100%) collected from wild geckos in Cambodia, Thailand and Vietnamwere were pan-susceptible. An India study found that all Salmonella Weltevreden strains isolated in their study carried virulence genes associated with Salmonella Pathogenicity Islands (SPIs), including invA/E, orgA, ttrC, ssaQ, mgtC, misL, and spi4D), as well as the enterotoxin gene (stn) and the hyperinvasive locus gene (hilA). With the exception of erythromycin resistance, all strains showed susceptibility to standard antimicrobials used in diarrhea treatment.
