A 47-year-old Belgian woman acquired yellow fever during a 1-week vacation in The Gambia; she had never been vaccinated against yellow fever. She died of massive gastrointestinal bleeding 7 days after the onset of the first symptoms. This dramatic case demonstrates that it is important for persons to be vaccinated against yellow fever before they travel to countries where yellow fever is endemi...

Laboratory rats were subcutaneously vaccinated with 100 live tetrathyridia ot Mesocestoides corti (Cestoda) and subsequently intraperitoneally challenged with 50 tetrathyridia. Necropsy 30 days postintection revealed that vaccinated rats harbored 97.4% fewer worms compared to control rats. In a second experiment, passive transfer of immunity was accomplished by immune serum from subcutaneously ...

The In-Ovo vaccination was first proved to be efficient for Marek’s vaccine by experiments performed by Sharma and Burmester in 1982. These authors demonstrated that chicks vaccinated In-Ovo at 18 days of embryo development against Marek’s Disease had better protection against virulent MD challenge carried out at 3 days of age as compared to those chicks vaccinated at hatch. At seven days of ag...

BACKGROUND & OBJECTIVES Andaman and Nicobar Islands of India, home to six primitive tribes, constituting about 10 per cent of the total population of these Islands have been detected with high endemicity of hepatitis B infection. During 2000, a total of 936 individuals ≤ 45 yr, negative for hepatitis B surface antigen (HBsAg) and antibody anti-HBs were vaccinated with three doses of a recombina...

From the beginning of the Middletown project the importance of determining the exact size and age distribution of the population was evident. Such information may not always be necessary in subsequent community-wide vaccination campaigns, but since one of our main objectives was to evaluate the degree of acceptance of oral vaccine in a typical small New England city, it was necessary to have ac...

test, chest X-ray, ESR, biopsy of the lesion whenever available, isolation of AFB if possible, and examination of the spinal, pleural or ascitic fluid depending upon the type of tuberculosis. Tuberculin test was done with 1 TU of purified protein derivative and was considered positive, when after 72 hours, an induration of more than 10 x 10 mm was seen. Presence of BCG scar was taken as confirm...
