Morphological and biochemical changes in the blood of horses naturally infected with Gasterophilus sp. larvae.

The research seeks to understand the changes initiated in horses’ blood due to natural infection of Gasterophilus sp. larval parasites. By comparing an infected group with a control group, the study finds notable differences in early and late stage infections but reports these changes as relatively minimal within biological norms.

Study Purpose and Methodology

• The primary aim of this study was to evaluate the effects of Gasterophilus sp. larval parasites on certain biochemical and morphological parameters in horse blood.
• Parasites from the Gasterophilus sp. genus are specific to equines such as horses, donkeys, mules, and zebras and their activity is linked to noteworthy variability in hematological and blood biochemical parameters.
• The experiment consisted of a test group of naturally infected horses and a control group of horses that were not infested.
• An investigation was carried out during two periods: in the early stages of the infestation and at the height of the parasitic invasion.

Findings and Conclusions

• Significant differences in terms of erythrocyte parameters were observed between horses at the early phase and those at the advanced stage of the parasitic infestation.
• The study found lower mean red and white blood cell counts and hemoglobin concentrations in horses at the advanced stage of invasion compared to those with early stage infection.
• Despite these differences, the values of these parameters still fell within the standard reference range for both groups, indicating that the changes, although statistically significant, were not severe enough to exceed normal health ranges.
• Similarly, all the measured biochemical parameters did not exceed the corresponding reference ranges in either group, including horses not infected with the larvae.
• The research concludes that despite being colonized by botfly larvae, the basic hematological and biochemical parameters of a horse’s blood remain largely unaffected. This insignificance suggests that the infection may not seriously impact the hematological health of horses.
