Based on systematic review of studies on Anaplasma species from India (Krishnamurthy et al., 2014) and World (Hungerford and Smith, 1997) from 1988 to 2017 and 1978–2017, respectively, using online databases and offline literatures, meta-analysis using meta package in R-Software was done. Prevalence of Anaplasma species in India and World were 11% [95% level, Confidence Interval[CI] 7–16%, Prediction Interval[PI] 1–69%] and 39% [95% level, CI 30–49%, PI 2–95%], and these were obtained using 31,117 and 46,365 samples, respectively. Period-wise analysis revealed high Anaplasma species prevalence before 2011 for India and the World than from 2011 through 2017. Zone-wise prevalence indicated high prevalence in Central zone [61%] and low in West and South zones [6%] in India, and continent-wise, it was high in South America [82%]. The studies used methods including blood smear examination, serology and nucleic acid-based techniques and revealed high prevalence in serology for India [34%] and World [46%], low prevalence by blood smear for India [7%] and World [21%], but higher sensitivity using nucleic acid-based techniques...
