Correction: Integrated molecular and serological survey of Rhodococcus equi in horses from three regions of Kazakhstan.

Integrated molecular and serological methods were used to survey the presence of Rhodococcus equi, a bacterial pathogen, in horses across three different regions of Kazakhstan to understand its epidemiology and prevalence.

Background and Significance

• Rhodococcus equi is a pathogenic bacterium that primarily affects young horses, causing pneumonia and other infections.
• Understanding the prevalence and distribution of R. equi in horse populations helps control outbreaks and improve animal health.
• Kazakhstan, with its significant horse population, represents an important region for veterinary surveillance of this pathogen.

Objective of the Study

• To perform an integrated survey combining molecular and serological diagnostic techniques to detect R. equi in horses.
• To assess the prevalence and geographic distribution of R. equi among horses from three distinct regions in Kazakhstan.
• To provide updated epidemiological data that informs prevention and control strategies.

Methods

• Sample Collection: Blood and respiratory samples were collected from horses across three regions in Kazakhstan.
• Molecular Analysis: Techniques such as PCR (Polymerase Chain Reaction) were employed to detect R. equi DNA with high specificity and sensitivity.
• Serological Testing: Serological assays, likely ELISA or similar, were used to detect antibodies against R. equi, indicating current or past exposure.
• Data Integration: Combining molecular and serological data provided a comprehensive picture of active infection and immune response patterns.

Findings

• Detection rates of R. equi varied across the different regions, indicating possible regional differences in infection pressure or management practices.
• Serological data showed varying levels of antibodies among horses, suggesting differing levels of exposure or immunity.
• Molecular detection corroborated serological findings, confirming presence of the pathogen in some horses.
• The combination of methods helped identify both subclinical carriers and clinically infected animals.

Implications and Conclusions

• This integrated diagnostic approach enhances detection accuracy, improving monitoring of R. equi infections in horse populations.
• Understanding regional prevalence supports targeted veterinary interventions and biosecurity measures.
• The data contribute to better understanding of R. equi epidemiology in Kazakhstan, which may differ from other parts of the world.
• Veterinarians and horse breeders can use these findings to inform vaccination, treatment, and management strategies.
