TL;DR: The duration of infection, frequency of eating raw fresh water fishes, and a series of liver function tests were studied in a group of 23 Korean symptomless cases with Clonorchis sinensis and showed no difference in either infected group and its contol group.
Abstract: The duration of infection, frequency of eating raw fresh water fishes, and a series of liver function tests were studied in a group of 23 Korean symptomless cases with Clonorchis sinensis, and compared with those in a control group of uninfected persons. Of 23 lightly infected cases, 11 cases who had been infected for 10 to 20 years was found the highest in percentage(47.8), and 2 had been infected for over 30 years. The frequency of eating raw fresh water fishes ranged from 2 to 35 times. The range of Stoll egg-counts in 23 cases varied from 600 to 8,600 eggs per gram of feces and the average value was approximately 2,800 eggs. A series of liver function tests examined showed normal value in all cases. These results showed no difference in either infected group and its contol group.

TL;DR: The results suggest that inhibition is not due to low adsorption rates, but rather to plaque formation by a small number of the sensitive fraction of the population and overgrowth by nonlysed cells.
Abstract: In the study of the relationship between bacteriophage and strains of staphylococci showing inhibition, slight differences were observed in the ability to adsorb phage between staphylococci of full phage sensitivity and those showing inhibition by phage. Only a few plaques were produced by inhibitory phages adsorbed on strains showing inhibition, whereas almost all of the phages adsorbed on corresponding phage-propagating strains produced plaques. Some strains showing inhibition were converted to full sensitivity to certain phages by heat shock or trypaflavine treatment. Treated strains adsorbed inhibitory phages to almost the same degree as nontreated strains, but most of the phages adsorbed on treated strains produced plaques. Killing was not always observed in cells adsorbing inhibitory phages. These results suggest that inhibition is not due to low adsorption rates, but rather to plaque formation by a small number of the sensitive fraction of the population and overgrowth by nonlysed cells.
