Development and survival of Ascaris suum eggs in deep litter of pigs.
SUMMARY Indoor transmission of Ascaris suum partly depends on the physico-chemical conditions in bedding material. Temperature, pH, aqueous ammonia, moisture, occurrence and development of A. suum eggs were therefore compared in different areas (resting, intermediate and latrine) of two deep litter pens on an organic farm in four seasons. There was some variation, but mean ammonia levels were g...
متن کاملVirulence conversion of Legionella pneumophila serogroup 1 by passage in guinea pigs and embryonated eggs.
When virulent Legionella pneumophila is passaged on supplemented Mueller-Hinton agar, it remains virulent for guinea pigs and embryonated hen eggs for two passages. However, by the fifth passage the cultures become avirulent for guinea pigs. Flagella were not produced by L. pneumophila on the first passage on supplemented Mueller-Hinton agar. In contrast, 12 passages on charcoal-yeast extract a...
متن کاملAntibody response of guinea pigs to trivalent parainfluenza virus vaccine prepared from embryonated eggs.
A trivalent parainfluenza virus vaccine has been tested in guinea pigs. The parainfluenza 2 virus vaccine component was superior in the magnitude of antibody titers, and in the ability to convert animals serologically after two doses of an undiluted or a 10-fold diluted vaccine. The parainfluenza 1 virus vaccine gave a higher percentage of conversion than parainfluenza 3 virus vaccine after adm...
متن کاملKinetics of circulating antigens in pigs experimentally infected with Taenia solium eggs.
Three groups of four piglets were experimentally infected with different doses (10(3), 10(4) and 10(5)) of Taenia solium eggs whereas a fourth group of two pigs received gravid proglottids. At autopsy 6 months post infection, the two latter pigs were heavily infected with more than 3000 living cysts per kg of muscle. Ten of the 12 other pigs harboured light infections, i.e. between 2 and 107 cy...
متن کاملHow Drosophila males make eggs: it is elemental.
Oogenesis in Drosophila requires a significant amount of phosphorus. Oocytes mature in follicles, each of which contains 15 highly polyploid, transcriptionally active chromosomes. We show that the demand for phosphorus is met in part from the male's ejaculate following mating. Females incorporate phosphorus-32 from radiolabelled males into their ovaries, specifically into their nucleic acids. M...
