Abstract
Postpartum cows commonly develop uterine diseases such as metritis and endometritis. Metritis and endometritis can lead to economic losses among farmers as it negatively affects the reproductive performances of dairy cows. Despite several studies reported, there is a lack of clear understanding on the most frequently reported uterine bacteria associated with metritis, clinical and subclinical endometritis. The objective of this study is to systematically review and identify the uterine microbiota of dairy cows associated with metritis, clinical and subclinical endometritis from different geographical areas along with their antimicrobial sensitivity spectrum and the most important risk factors. Guided by Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) 2020, a systematic review has been conducted on uterine micro biota of dairy cows with metritis, clinical and subclinical endometritis using studies published from 2012 until 2021 in SCOPUS and Google Scholar databases. There were a total of 36 published papers included for a full assessment. From the thematic analysis, this review presented five main themes which include (1) sampling methods; (2) microbiota distribution; (3) geographical distribution; (4) risk factors and (5) Antimicrobial Susceptibility Testing (AST) fmdings. Trueperella pyogenes and Escherichia coli are among the isolates that were commonly found across all the studies reviewed. Trueperella pyogenes was found to be highly associated with clinical endometritis while Escherichia coli was linked to most of the subclinical endometritis cases. Meanwhile the review showed that various types of bacteria can cause metritis in cows. This systematic review provides an overview of a current knowledge and a clear comparison on the uterine microbes of dairy cattle having metritis, clinical and subclinical endometritis from different geographical areas. The findings would aid further studies in future on therapeutic, preventive and control measures for metritis, clinical and subclinical endometritis in dairy cows, thereby reducing related financial losses by farmers.
