JOURNAL FREE ACCESSThe epidemiological view of Au antigen in Ghana was summarized as follows:
1. Over all incidence of Au antigen in the general population (healthy persons and non-jaundiced patients) of Ghana was 6.2%.
2. Au antigen was rarely found in infants and young children under age 4. The incidence gradually increased, reaching a maximum of about 10% at age 10, then gradually decreased with age.
3. Higher incidence was calculated for male (6.7%) than that of female (4.9%).
4. No obvious difference was observed among various tribes.
5. Lower incidence of Au antigen was noted in the Coastal area (5.2%) than in Forest (7.1%) and Savanna areas (7.4%).View full abstractDownload PDF (815K) -

JOURNAL FREE ACCESSExtending from 1968 to 1970, hemagglutination-inhibition (HI) tests against Japanese encephalitis virus (JEV) were carried out on 432 inpatients of a sanatorium in Fukuoka City. Most of them were tuberculosis patients.
The results obtained are as follows:
1. In June 1968, the HI positive (titers of 1: 10 or more) rate was 47.7% on the average, and the positive rate increased with age. After three years, the positive rate was risen to 59.8% with vaccination.
2. Most of the HI negative persons were vaccinated by two subcutaneous injections of 1.0 ml of JEV vaccine at weekly intervals, and the remainders received a single injection. They were bled a month after the first injection. The rate changed to HI positive after vaccination of each year was 33.9%, 55.3%, and 45.7%, respectively, and these rates were lower than the result on healthy adults.
3. It was suspected that antibody response to vaccination of the old age group over fifty-five years of age was weaker than that of the younger age group.
4. The HI antibody level acquired by vaccination was not maintained for long term; 17 out of 24 cases changed to HI positive after the vaccination returned to HI negative after a year.View full abstractDownload PDF (790K) -

JOURNAL FREE ACCESSIt is well established that oral infection in mice with S. enteritidis is influenced by the status of intestinal microbial flora and the normal flora can provide resistance to the salmonella infection. In this report, changes in the intestinal flora and the susceptibility to S. enteritidis No. 11 strain in mice after oral administration of several antibiotics were investigated.
There observed significant increase of mortality by oral challenge of S. enteritidis after the treatment (oral administration) with Erythromycin (EM), lincomycin (LCM), and kanamycin (KM). However, increase of mortality was not observed in mice treated with Streptomycin (SM) or Nalidixic acid (NA). Although failed to increase the mortality of mice, SM, like EM, considerably promoted the growth of S. enteritidis in the intestinal tract. On the contrary, in the NA-treated mouse intestine the organisms diminished in number.
The significant decrease in number of Enterococci and Anaerobes-especially Gram-positive bacilli-in the intestine was demonstrated in mice treated with EM. On the other hand, in mice treated with NA, coliform bacteria decreased remarkably in number. Furthermore, SM treatment reduced the number of coliform bacteria and Enterococci.
When a strain of Enterococci, BIO-4R, was given to EM- or SM-treated mice the susceptibility to S. enteritidis was notably suppressed. Whereas, the oral administration of Clostridium butyricum MB strain to EM-treated mice made them more susceptible against the salmonella infection.
From these data, it is concluded that Enterococci and Gram-positive Anaerobes such as Corynebacterium may be the most important flora as a resistance-inducing factor in mice against salmonella enteritidis infection.View full abstractDownload PDF (1578K) -
