NCBI PD link for serovar Litchfield: https://www.ncbi.nlm.nih.gov/pathogens/isolates/#(taxgroup_name:%22Salmonella%20enterica%22)%20AND%20computed_types:(%22serotype=Litchfield%22)
Genetic characteristics: Serovar Litchfield has been found to be polyphyletic with two lineages identified. Medalla et al. reported that Litchfield (2.9%) has the second highest proportion of isolates resistant to ciprofloxacin in their study. González-Sanz et al. reported serovar Litchfield isolated in Spain from 2001 to 2005 with the presence of blaCTX-M-1. Yamazaki et al. reported that a plasmid pRY82, which mediates lactose-utilization, was isolated from a serovar Litchfield strain.
Animal reservoir: Poultry and turtles may be potential hosts.
