Abstract

Paratuberculosis, also known as Johne's disease, is a chronic wasting disease caused by Mycobacterium avium subs paratuberculosis in ruminants. This disease causes a significant economic impact. The said disease led to a significantly reduced milk production of the affected dairy sheep or goats increased cost for diagnosis, treatment, and culling of infected animals. The majority of research focused on cattle, and the knowledge of the current trends of prevalence involving Johne's disease among small ruminants and deer in three different regions, namely Southeast Asia, Asia, and worldwide countries, is not well documented till date. Therefore, this systematic review aims to compile and analyse the current trends of prevalence of Johne's disease among small ruminants and deer in three different regions, namely Southeast Asia, Asia, and worldwide countries, from papers published within 2010- 2021. The SCOPUS database was used to search for published studies on the prevalence of Johne's disease. Prior to the final selection of studies, an initial screening for basic eligibility and a comprehensive assessment of quality. The search yielded a total of 297 studies. Following the completion of data extraction and synthesis, 21 studies were chosen. No study was recorded or published for Southeast Asia, whereas ten studies were published from 5 countries in Asia. Worldwide, ten countries only reported 11 studies. Asia and worldwide countries attributed data for sheep, goats, and deer. The most common diagnostic tool used in these three regions was ELISA (Enzyme-linked immunosorbent assay). These regions' prevalence surveys are not comprehensive enough to correctly establish the true prevalence of Johne's disease among small ruminant and deer populations involved in these three regions. Thus, this study suggests that future prevalence studies of Johne's disease among the small ruminant and deer populations should be done more systematically and holistically, especially for Southeast Asia countries.
