A Preliminiary Note on the Nature and Pathology of the Disease Known as “Surra,” Affecting Horses and Mules in India.

This research article presents an initial investigation into the disease called “Surra,” which significantly affects horses and mules in India, leading to high mortality rates and considerable economic loss. The research aims to identify the cause of the disease and to provide information that could lead to effective treatment.

The Significance of the Study

• The study investigates the disease “Surra,” which affects horses and mules and causes remarkable losses each year in India and Myanmar.
• In 1889 and 1890 alone, this disease resulted in a loss of nearly 13,000 rupees due to the death of several animals in one regiment alone.
• This high economic loss justified the necessity for an in-depth investigation aimed at finding the cause of the disease and seeking a possible cure.

The Disease Under Study: Surra

• The disease of interest, Surra, was identified by veterinary surgeons who were caring for the affected animals at the time of the study.
• This disease has shown a remarkably high fatality rate, with any treatment options attempted so far proving ineffective.

Symptoms of Surra

• The disease is characterised by a range of symptoms including progressive anaemia, lethargy, weight loss, a certain type of rash in the eye (conjunctival petechiae), and increase in the amount of urine produced.
• The affected animals eventually succumb to death due to exhaustion.
• In many instances, the urine contains proteins, a condition known as albuminuria. In a specific case, the urine was also found to contain a pigment believed to be urohaematoporphyrin, although a spectroscopic analysis could not be conducted to confirm this.

Objective of the Research

• The objective of this paper is to provide preliminary information on the ongoing research into Surra, focusing on the broad results obtained so far.
• The detailed specifics regarding the abnormal observations noticed and their implications will be reserved for subsequent, more detailed work.
