This study was undertaken to investigate congenital microphthalmia that occurred at a pig farm in Kyongbuk Korea [R.]. These microphthalmic piglets composed of 20 piglets farrowed by 3 different sows (1, 11 and 8 piglets by No. 1,2 and 3 sow, respectively) that were apparently normal during pregnancy and after parturition. Attempts were made to know epidemiological findings and histopathological changes of these piglets

Basic biological and epidemiological observation on eperythrozoonosis like disease of swine in Korea R. was taken, using 157 naturally affected pigs and blood samples of 250 normal pigs. Although infection rates, morphology and sizes of the organisms in stained blood films varied depending on the season, all of the affected pigs showed positive infection and the normal pigs were found 54% positive over the year. The organisms appeared to have 5 morphological forms with sizes of 0.5-5.0 micron but the sizes had increment to 1.4-8.5 micron with cytoplasmic granules when the blood was stored under 0 deg C for more than 1 week or -20 deg C for 24 hrs.
