The composition and application of a single, chemically defined medium or growth and sporulation of Bacillus subtilis is described. At 37 degrees C cells grew with a doubling time of about 40 min; cultures attained near-maximal spore formation (70 to 80% by 12 h after the end of exponential growth and produced 1 X 10(9) to 2 X 10(9) heat-resistant free spores at 24 h. Dipicolinic acid productio...

Nano-sized gold has become an important material in various fields of science and technology, where control over the size and crystallography is desired to tailor the functionality. Gold crystallizes in the face-centered cubic (fcc) phase, and its hexagonal closed packed (hcp) structure is a very unusual and rare phase. Stable Au hcp phase has been reported to form in nanoparticles at the tips ...

During chromosome segregation, kinetochores form dynamic connections with spindle microtubules. In vertebrates, these attachments require the activities of a number of outer kinetochore proteins, including CENP-F [1, 2] and the widely conserved microtubule-associated protein CLASP [3]. Here, we investigate the functional relationship between HCP-1/2, two redundant CENP-F-like proteins, and CLAS...

1. Antisera, prepared against extracts of cells and spores of Bacillus subtilis, were used in immunoelectrophoretic studies of the changes occurring in cell extracts during the course of spore formation. 2. At least 15 antigens could be detected in vegetative-cell extracts by the antiserum prepared against cell extracts and at least seven could be demonstrated in spore extracts by the homologou...

We report the draft genome sequence of Bacillus thuringiensis strain LM1212, which differentiates into crystal producers or spore formers during the stationary phase. Availability of this genome sequence will facilitate the study of spore formation, crystal formation, cell differentiation, and evolution of B. thuringiensis.

Hexachlorophene (HCP) inhibits both endogenous and exogenous respiration (oxygen uptake) in Bacillus megaterium, without sparing by any of several substrates. The inhibition is maximal when the cells are treated with 8 mug of HCP per mg of cells (dry weight), which corresponds to the minimal lethal dose. Levels as low as 2 mug/mg are inhibitory but not lethal. HCP also inhibits the respiration ...

OBJECTIVE Investigate determinants of receiving healthcare provider (HCP) recommendations for seasonal and H1N1 influenza vaccinations. METHODS Using a United States national sample of adults 18 + from the National 2009 H1N1 Flu Survey, multivariate regression models estimated the likelihood of receiving a HCP recommendation. Covariates included demographics, socioeconomic status, and Advisor...

BACKGROUND Although under debate, routine screening for intimate partner violence (IPV) is recommended in health care settings. This study explored the utility of different screening and referral strategies for women exposed to IPV in primary health care. METHODS Using a randomized controlled trial design we compared two screening strategies (health care providers [HCP] versus audio computer-...

BACKGROUND Conflicts between professional duties and fear of influenza transmission to family members may arise among health care professionals (HCP). METHODS We surveyed employees at our university hospital regarding ethical issues arising during the management of an influenza pandemic. RESULTS Of 644 respondents, 182 (28%) agreed that it would be professionally acceptable for HCP to aband...

This report contains CDC guidance that augments the 2011 recommendations of the Advisory Committee on Immunization Practices (ACIP) for evaluating hepatitis B protection among health-care personnel (HCP) and administering post-exposure prophylaxis. Explicit guidance is provided for persons working, training, or volunteering in health-care settings who have documented hepatitis B (HepB) vaccinat...
