Clinical and clinicopathologic findings in two foals infected with Bacillus piliformis.

This study presents clinical data on two cases of foals that were infected with Bacillus piliformis, which causes a rare and commonly fatal disease known as Tyzzer’s disease, and discusses the unsuccessful attempts to treat them.

Study Overview

• The paper discusses the clinical and clinicopathologic findings in two foals (young horses) infected with Bacillus piliformis. This bacterium causes Tyzzer’s disease, which is often fatal and rarely seen clinically because of its peracute (suddenly severe) course.
• The authors detail the various symptoms, clinicopathologic abnormalities and the unsuccessful treatment attempts in these two cases.

Clinical and Clinicopathologic Findings

• The researchers observed common clinicopathologic abnormalities in both foals.
• These included leukopenia (a decrease in the number of white blood cells), hyperfibrinogenemia (an increased level of fibrinogen, a protein involved in blood clotting, in the blood), metabolic acidosis (a condition where too much acid builds up in the body because of the food metabolism), and hypoglycemia (low blood sugar).

Treatment Attempts

• Despite efforts, treatment was unsuccessful in both cases.
• Although this paper doesn’t detail the exact treatments used, the outcome underscores the seriousness and notoriously difficult nature of curing Tyzzer’s disease in foals.

Conclusion and Significance

• This study offers valuable clinical data on the rarely-observed, deadly Tyzzer’s disease in foals.
• While the treatment attempts were unsuccessful, reporting on such cases contributes to the wider veterinary knowledge about the disease, potentially guiding future studies into more effective treatments.
