Regional scrapings from Hospital, Chennai were screened for different pathogens including Acanthamoeba. Of these, 563 (25.4 percent) were positive for bacterial pathogens, 660 (29.8 percent) had fungal pathogens. Acanthamoeba was present from 372 cases in 44 (2 percent) which fulfilled the criteria for suspecting Acanthamoeba keratitis.

Among these 44 Acanthamoeba positive cases, 18(40.9 percent) has associated bacterial pathogens while 12(27.83 percent) hand fungi and 2(4.5 percent) had both bacteria and fungi.
