Prevalence of hydatid cysts in livestock animals in Xinjiang, China.

Abstract: Hydatid worms, hosted by humans and animals, impose serious human health risk and cause significant livestock production loss. To better understand the disease infection status in Xinjiang, China, we investigated the disease epidemics in 4 livestock animals, i.e., cattle, sheep (both sheep and goat), camels, and horses, slaughtered at the abattoirs in Urumqi, Yining, Tacheng, and Altay areas. The results showed that the animals were infected at different rates, in the order of sheep (9.8%), cattle (8.4%), camels (6.8%), and horses (4.3%). The infection rates were found to be different between the abattoirs in various regions even for the same animals. For sheep, the rates increased significantly as the animals grew older. It was 1.9% before 1 year of age and increased to 8.2% in the age of 1-2 years, and further increased to 12.3% when the animals were 3-4 years old, and reached 17.2% when they were 5-6 year old. Sheep older than 6 years had an infection rate of 19.5%. This study demonstrates that the 4 livestock animals in the pastoral areas in Xinjiang were infected by the parasites to various extend. This study is the first systematic investigation of the hydatid worms in various livestock animals in Xinjiang, China, which provides epidemiological information about the infection of hydatid worms in livestock, and is valuable in developing strategies for prevention and control of the hydatid disease.

This article studies the prevalence of Hydatid worms in livestock animals in Xinjiang, China and how their infection rates differ by age and region. This research could help in devising strategies to control and prevent the spread of the Hydatid disease.

Objective

The key purpose of the study was to understand the prevalence and age-related incidence of hydatid worms in four types of livestock animals – cattle, sheep, camels, and horses – in Xinjiang, a large region in Northwest China. The gathered information aims to contribute towards the development of strategies and measures to control the spread of the disease amongst livestock.

Methodology

  • The researchers performed this study on livestock slaughtered at abattoirs scattered across four different areas: Urumqi, Yining, Tacheng, and Altay.
  • Through examination of the slaughtered animals, the researchers were able to determine the presence of hydatid cysts and calculate the infection rates based on the data collected.
  • They also analysed the age-related incidence of the disease by dividing the sheep into different age groups: before 1 year of age, 1-2 years, 3-4 years, 5-6 years, and older than 6 years.

Findings

  • The study found that the livestock were infected at different rates: sheep with 9.8%, cattle with 8.4%, camels with 6.8%, and horses with 4.3%.
  • The infection rates varied in different abattoirs in the various regions, implying that geographical variance may have an impact on infection rates.
  • The data also showed that infection rates in sheep noticeably increased as the animals grew older: 1.9% before 1 year old, 8.2% in 1-2 year old sheep, 12.3% in 3-4 year-old sheep, 17.2% in 5-6 year old animals, and 19.5% in those that were more than 6 years old. This suggests that there may be prolonged immunity or resistance against the parasites.

Relevance

The research is significant as it is the first systematic study investigating hydatid worms across different types of livestock in Xinjiang, China. The insights gathered provide valuable epidemiological data that could contribute to formulating more targeted strategies and measures to prevent and control the hydatid disease, a parasitic infection posing considerable threat to human health and livestock production.
