infection by m. tuberculosis can be demonstrated by tuberculin testing. on sequential ppd some person show a marked increase in the size of their skin reactions which may not be due to recent or past tuberculous infection. this phenomenon (booster effect) can occur as soon as a week after the initial test and persist for as long as a year. methods and materials: the purpose of this research is ...

background: haemonchus contortus causes severe economic losses in small ru-minants, so this study was conducted to study the uv effect on h. contortus larvae and its protective effect. methods: sixteen male goats were divided into 5 groups, control infected, con-trol uninfected and uv 30minutes exposure; uv 60minutes exposure and uv booster 60minutes exposure. the uv groups were exposed to uv i...

We present results of the commissioning of a new injector for the Brazilian Synchrotron Light Source. The new injector consists of the existing 125-MeV LINAC and a new 500-MeV booster synchrotron. At present, about 40 mA can be injected into the booster and about 15 mA can be ramped up to 500 MeV at a repetition rate of 0.17 Hz. The new injector has allowed the accumulation of up to 540 mA in t...

One alternative for management of brucellosis in Yellowstone National Park bison (Bison bison) is vaccination of calves and yearlings. Although Brucella abortus strain RB51 vaccination protects bison against experimental challenge, the effect of booster vaccinations was unknown. This study characterized immunologic responses after dart or booster vaccination of bison with Brucella abortus strai...

BACKGROUND Haemonchus contortus causes severe economic losses in small ruminants, so this study was conducted to study the UV effect on H. contortus larvae and its protective effect. METHODS Sixteen male goats were divided into 5 groups, control infected, control uninfected and UV 30 minutes exposure; UV 60 minutes exposure and UV booster 60 minutes exposure. The UV groups were exposed to UV ...

In a prospective, controlled, randomized, multicenter study the immunogenicity and tolerance of a single vaccination (day 0) and two (day 0, 28) booster vaccinations against diphtheria were compared in subjects who had received their last diphtheria vaccination more than 10 years ago. 415 subjects received the first booster vaccination, and 203 were vaccinated twice. The geometric mean diphther...

This phase II study evaluated the effect of chloroquine on the specific CD8(+) T-cell responses to and the safety of a booster dose of investigational human immunodeficiency virus type 1 (HIV-1) F4/AS01(B) vaccine containing 10 μg of recombinant fusion protein (F4) adjuvanted with the AS01(B) adjuvant system. Healthy adults aged 21 to 41 years, primed 3 years before with two F4/AS01(B) doses co...

BACKGROUND Haemophilus influenzae serotype b (Hib) has yet to be eliminated despite the implementation of routine infant immunization programs. There is no consensus regarding the number of primary vaccine doses and an optimal schedule for the booster dose. We sought to evaluate the effect of a booster dose after receiving the primary series on the long-term disease incidence. METHODS A stoch...

STUDY OBJECTIVE This study compares the effect of a brief motivational intervention for alcohol plus a booster given to emergency department (ED) patients with subcritical injuries from a motor vehicle crash with the effect of brief motivational intervention for alcohol plus a booster in patients treated for non-motor vehicle crash-related injuries. METHODS A randomized controlled trial (n=53...
