| helical, motile mycoplasmas associated with flowers and honey bees in california. | spiroplasmas were cultured from nonsurface-sterilized flowers of magnolia tree (magnolia grandiflora l.) and tulip tree (liriodendron tulipfera l.) in alameda, solano, and yolo counties in california. spiroplasmas were also isolated from honey bees (apis mellifera l.) collected in the vicinity of davis and berkeley, ca. most of the isolates grew relatively slowly at 31 or 37 degrees c reaching maximum population at 31 degrees c in 8-10 days. the flower isolates were serologically indistinguishab ... | 1981 | 7214240 |
| comparative analysis of paenibacillus larvae genotypes isolated in connecticut. | ninety-six strains of paenibacillus larvae, causative agent of american foulbrood in honey bee (apis mellifera) larvae, collected from connecticut, usa (ct), honey bees, and 12 p. larvae strains not from ct, were genotyped via eric-pcr and xbai-rflp analysis. all ct-isolates, five strains isolated in south america, three strains from north america (not ct), and one strain isolated in australia grouped into the eric i genotype. three p. larvae formerly subsp. pulvifaciens strains grouped into eri ... | 2015 | 25929327 |
| using a hazard quotient to evaluate pesticide residues detected in pollen trapped from honey bees (apis mellifera) in connecticut. | analysis of pollen trapped from honey bees as they return to their hives provides a method of monitoring fluctuations in one route of pesticide exposure over location and time. we collected pollen from apiaries in five locations in connecticut, including urban, rural, and mixed agricultural sites, for periods from two to five years. pollen was analyzed for pesticide residues using a standard extraction method widely used for pesticides (quechers) and liquid chromatography/mass spectrometric anal ... | 2013 | 24143241 |
