We have designed a method for the large scale isolation of pure and highly active subunits
from yeast cytoplasmic ribosomes. The method consists of the incubation of yeast protoplasts …

Flagella production inCampylobacter jejuni 81116 is subject to phase variation; the bacterium
is able to switch its flagellum synthesis, and thereby its motility, on and off. Under standard …

Het belangrijkste doel van vaccinatie is bescherming van het individu tegen ziekte. Vaccins
worden slechts goedgekeurd bij een gunstige baten-risicoverhouding voor de …

A DNA fragment encoding both haemolysin and sphingomyelinase C activity was cloned from
L. interrogans serovar hardjo. Initial clones were obtained by screening a genomic library …

Cowdria ruminantium, the causative agent of heartwater disease, expresses an immunodominant
and conserved 32-kDa protein (MAP1; formerly called Cr32), which is currently in use …

Cowdria organisms were purified by density gradient centrifugation and the DNA used to
construct expression libraries. The immunodominant Cr32 protein was purified and its N-…

Seasonal influenza causes more morbidity and mortality in older adults than in young adults,
apparently because of a decline in immune function with increasing age, known as …

Seventeen temperature-sensitive mutants of equine arteritis virus were isolated using 5-fluorouracil,
o-methylhydroxylamine and ethyl methanesulphonate as mutagens. The mutants …

Screening of 7680 S. enterica serovar Enteritidis mutants for attenuation in a chicken
macrophage infection model yielded a series of mutants including several with defects in …
