Integrated molecular and serological survey of Rhodococcus equi in horses from three regions of Kazakhstan
Phylogenetic analysis placed the Kazakhstani isolate within a clade of equine-associated <i>R. equi</i> strains reported from Europe and East Asia (>99.5% identity). We provide molecularly confirmed evidence of <i>R. equi</i> circulation in horses from three regions of Kazakhstan, with higher seropositivity in foals and focal farm-level clustering. Findings support the need for broader geographic sampling, test validation against reference sera, and incorporation of management/risk-factor data. Limitations include the regional scope, small number of foals, and absence of environmental or human sampling.
