Neonatal viral diarrhoeas.
Abstract: Diarrhoea continues to be one of the more common and
important causes of economic loss in young animals (Anon
1978). Virus particles identified as rotaviruses, coronaviruses,
calci-like viruses, astroviruses, parvoviruses, and several others
have been detected by direct electron microscopy of ultracen-
trifuged samples of diarrhoeic faeces from young animals and
human infants over the past 20 years. Despite numerous stud-
ies on the many aetiological agents associated with neonatal
viral diarrhoea in recent years (Tzipori 1985), the challenge
for today’s new veterinary graduate is similar to that faced
by Bill Snowdon when he graduated from the University of
Sydney in 1948. When investigating outbreaks of diarrhoea
in calves, piglets, foals, kids, and lambs in the field, or in
various species of wildlife kept in zoos, it is still difficult to
know which bacteria, viruses or protozoa are responsible for
the diarrhoea (Blood and Radostits 1989).

This research article investigates the role of various viruses in causing diarrhoea in newborn animals, an issue which continues to cause significant economic loss in the animal industry. Despite identified viruses such as rotaviruses, coronaviruses, and others present in faeces samples and numerous studies on the subject, it remains challenging to definitively identify the microorganism responsible for the diarrhoea.
Introduction and Background
- Diarrhoea is identified as a persistent health and economic problem in young farm animals such as calves, piglets, foals, kids, and lambs, as well as certain species of wildlife in zoos.
- This article recognises a number of potential viral causes of diarrhoea, including rotaviruses, coronaviruses, calciviruses, astroviruses, parvoviruses, among others. These have been identified through electron microscopy of ultra-centrifuged samples of diarrhoeic faeces from young animals and human infants over the past two decades.
Diagnosis Challenges in Neonatal Viral Diarrhoea
- The vast array of possible viral agents and their similarities make it difficult for veterinarians to pinpoint the exact cause of the diarrhoea in animals.
- When investigating outbreaks of diarrhoea, veterinarians face the same challenges as Bill Snowdon did when he graduated from the University of Sydney in 1948, indicating the persistent difficulty in this field of veterinary medicine.
- The article suggests that it is not only viruses that pose a challenge in identifying the cause of diarrhoea; other microorganisms such as bacteria and protozoa complicate the diagnostic process.
Aim of the Review
- Given the economic and health impact diarrhoea has on young animals and the animal industry, this research paper aims to contribute to the understanding and knowledge about the etiological agents that cause neonatal viral diarrhoea.
- The research might lead to better diagnostic procedures, improved treatment strategies, and ultimately, a reduction in animal suffering and economic losses.
