Cone-rod dystrophy 1 (cord1) is a recessive condition that occurs naturally in miniature longhaired dachshunds (MLHDs). We mapped the cord1 locus to a region of canine chromosome CFA15 that is syntenic with a region of human chromosome 14 (HSA14q11.2) containing the retinitis pigmentosa GTPase regulator-interacting protein 1 (RPGRIP1) gene. Mutations in(More)
An essential pre-mRNA splicing factor, the product of the PRP38 gene, has been genetically identified in a screen of temperature-sensitive mutants of Saccharomyces cerevisiae. Shifting temperature-sensitive prp38 cultures from 23 to 37 degrees C prevents the first cleavage-ligation event in the excision of introns from mRNA precursors. In vitro splicing(More)
We conducted experiments with a previously described rabbit model of Escherichia coli-induced preterm pregnancy loss. Does at 70% gestation were inoculated hysteroscopically with 0.2 ml of Escherichia coli (10(5) colony-forming units per milliliter) or saline solution. Animals were randomly assigned to either receive treatment with ampicillin-sulbactam(More)
Two mutants of Streptococcus lactis ATCC 11454 have been isolated which possess an impaired lactose-fermenting capacity; galactose utilization is also affected, but to a lesser extent. Although the Embden-Meyerhof-Parnas pathway is the major, if not the sole, pathway of carbohydrate metabolism in the three strains, the fermentation end products of the(More)
The cross-reactive immune response occurs when an immune system is exposed to one pathogen and challenged with a related but different pathogen; for example, vaccination with one strain of influenza and challenge with a wildtype strain. In this way immunolog-ical memory functions as an associative memory. A discrete object model of the immune system was(More)
OBJECTIVE Our purpose was to evaluate the effect of maternal administration of ampicillin-sulbactam on group B streptococcal colonization and bacteremia in newborn rabbits. STUDY DESIGN Before induction of labor, timed pregnant New Zealand White rabbits on day 29 of a 31-day gestation received no therapy or ampicillin-sulbactam 50 mg/kg intramuscularly as(More)
OBJECTIVE To compare aztreonam in a standard dose with two gentamicin doses in the early treatment of experimental intra-amniotic infection in rabbits induced by intracervical inoculation with Escherichia coli. METHODS Timed pregnant rabbits on day 21 (70% of gestation) were inoculated intracervically with 10(4)-10(5) colony-forming units of E coli. After(More)
