This systematic review and meta-analysis synthesizes global epidemiological data on bovine postpartum endometritis and E. coli pathogenesis to inform clinical prevention and control strategies. Clinical endometritis persisting beyond three weeks postpartum affects approximately 15–20% of dairy cows globally, rising to 40% under high-risk conditions, driven by multifactorial pathogenesis including E. coli virulence factors (adhesins, toxins, LPS, biofilm) that collectively promote bacterial colonization, immune activation, and tissue damage.
Systematic review combined with meta-analysis. Dairy cows in the postpartum period; studies reporting bovine endometritis prevalence, E. coli detection, virulence factors, or treatment interventions.. Intervention: Descriptive synthesis of E. coli virulence factors (adhesins, toxins, LPS, capsule antigens, siderophores, biofilm formation) and existing and emerging prevention and control strategies for bovine endometritis.. Global; searches identified studies reporting incidence and spatial distribution of bovine endometritis with regional differences and potential contributing factors..
Clinical endometritis persisting beyond the first three weeks postpartum is generally reported in approximately 15–20% of cows Under high-risk conditions, postpartum uterine diseases may affect up to 40% of dairy cows, especially in high-producing cows experiencing increased metabolic load and periparturient stress E. coli virulence depends on synergistic action of multiple factors: FimH and PapG adhesins for colonization, HlyA, CNF1, and LPS for tissue damage, K1 and O antigens for immune evasion, siderophores for nutrient acquisition, and biofilm formation for persistent infection
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
Clinicians and researchers should recognize that bovine postpartum endometritis is a multifactorial disease affecting 15–20% of dairy cows globally (up to 40% under stress), driven by E. coli virulence mechanisms that depend on synergistic bacterial factors. Current antibiotic-based treatment faces emerging resistance and microbiota disruption, necessitating evaluation of alternative prevention and control strategies informed by pathogenic mechanisms.
This is a systematic review and meta-analysis synthesizing epidemiological patterns, pathogenic mechanisms, and treatment strategies for bovine endometritis to provide clinical reference for prevention and control, not a primary empirical trial.

Dairy cow endometritis is a common postpartum disease influenced by geographic, management, environmental, diagnostic, and socio-economic factors. Escherichia coli (E. coli) was prioritized for its early colonization, frequent detection, and key inflammatory role in endometritis. Its pathogenicity depends on virulence factors, including adhesins, toxins, lipopolysaccharides (LPS), capsule antigens, siderophores, and biofilm formation. These factors jointly promote bacterial colonization, immune activation, tissue damage, and disease progression. This study combines a systematic review and meta-analysis to assess the prevalence and distribution of E. coli, and provides a descriptive synthesis of its key virulence factors, pathogenic mechanisms, and treatment strategies. Unlike descriptive reviews, this study links epidemiological patterns with pathogenic mechanisms and therapies. Main limitations include high epidemiological heterogeneity and limited clinical validation of therapeutic strategies. It further evaluates current treatment strategies to assess the feasibility of novel therapies, aiming to provide a reference for precise prevention and control in clinical practice.
