About 11 faecal samples from various regions of Tamil Nadu and Andhra Pradesh containing mixed spectrum of Eimeria species detected by morphometry viz. 15.4 × 11.2, 28.5 × 20.3, 31.1 × 18.5, 13.2 × 12.4, 20.8 × 17.5 and 22 × 18 μm for E. acervulina, E. brunetti, E. maxima, E. mitis, E. necatrix, E. praecox and E. tenella respectively were taken for the study. The oocysts were concentrated and purified using faecal harvest protocol. The genomic DNA is extracted as per kit protocol. The amplicons of sizes 539 bp (E. tenella) and 460 bp (E. mitis) obtained could be visualised in a single lane for the multiplex PCR assay using sequence characterized amplified region primers.
