Study on prevalence and associated risk factors of epizootic lymphangitis in equine in Nagele Arsi town, southeastern Ethiopia.
Abstract: Epizootic lymphangitis is a contagious, chronic and overwhelming disease of equids, characterized by chronic discharging skin nodules. This study was aimed to investigate the prevalence and associated risk factors of epizootic lymphangitis in equines at Nagele Arsi town, southeastern Ethiopia. A cross-sectional study using a random sampling technique was employed from December 2021 to June 2022 via clinical and microscopic examinations of the lesions. The overall prevalence of epizootic lymphangitis was 4.37% with a prevalence of 6.69%, 0.72%, and 0% in horses, donkeys, and mules, respectively. The sex, species, harness type, season, and body condition scores of equids have shown statistically significant differences (p < 0.05) with the prevalence of epizootic lymphangitis. Macroscopically, the lesions revealed varying degrees of nodule to ulcer on the sternum, limbs, face, and cervical region of the equine. Upon giemsa stain, fungal hyphae with a halo (unstained capsule-like) structure were observed. Histologically, pyogranulomatous inflammation with fibroplasia was appreciated. In conclusion, epizootic lymphangitis was rampant in the study area. This requires a detailed investigation incorporating a large sample size using fungal culture and other molecular techniques including PCR.

The research paper investigates the appearance and risk factors of epizootic lymphangitis in equines in the town of Nagele Arsi, southeastern Ethiopia. Equines that exhibited this disease were horses, donkeys, and mules, with horses being the most affected.
Research Methods
- The researchers adopted a cross-sectional study approach using a random sampling technique to carry out their investigations, stretching from December 2021 to June 2022.
- Both clinical and microscopic examinations of the lesions were performed to identify instances of epizootic lymphangitis among the samples.
- Variables such as the sex, species, harness type, season, and body condition scores of the equines were considered for the study, their significance tested against the prevalence of the disease.
Findings
- The overall prevalence of Epizootic lymphangitis was found to be 4.37% among all equines studied, distributed unevenly across the different species. It was found in 6.69% of horses, 0.72% of donkeys and absent in mules.
- The research further discovered that the equine’s sex, species, harness type, season, and body condition scores all significantly influenced the prevalence of the disease.
- Macroscopic investigation of the lesions revealed varying degrees of nodules to ulcers on the sternum, limbs, face, and cervical region of the equines.
- The researchers observed fungal hyphae surrounded by an unstained capsule-like structure in the lesions during the microscopic examination.
- From the histological viewpoint, the researchers appreciated the presence of pyogranulomatous inflammation with fibroplasia in the affected regions.
Conclusion
- The prevalence of Epizootic lymphangitis was quite high in the study area. This finding pointed towards the need for a more detailed investigation of the disease, inclusive of a larger sample size and advanced molecular diagnostic techniques like fungal cultures and Polymerase Chain Reaction (PCR).
