Eimeria spp. in Cattle: A Global Systematic Review and Meta‐Analysis

= 99.4%). Prevalence ranged from 27.1% (2012-2018) to 40.8% (≤2011), 29.5% in Asia to 67.4% in Central America and 1% (Macedonia) to 94.2% (Costa Rica), though some national estimates were based on single studies. Calves <1 year accounted for the highest proportion of positives (56.3%, 95% CI: 46.2-65.8), and females showed higher infection rates (66.7%, 95% CI: 61.7-71.4). Infections peaked during warm and humid periods. Sixteen Eimeria species were identified in cattle; E. bovis and E. zuernii predominated, followed by E. auburnensis, E. ellipsoidalis, E. cylindrica and E. alabamensis. Sensitivity analyses confirmed estimate stability. Meta-regression identified sample size as the only significant predictor, explaining 4% of heterogeneity. Publication bias was detected (p < 0.05). Eimeria infection imposes a substantial global burden in cattle, particularly among calves and females. Although sample size influenced reported prevalence, marked heterogeneity persists. Standardized reporting and geographically balanced studies are needed to better inform global coccidiosis control strategies.
