SYNOPSIS The growth of 100 staphylococcal strains in normal rabbit serum was studied. Determinations were carried out by the tube method previously described and by a new plate method, and the results agreed in both cases. The strains of staphylococci used differed in the production of bound coagulase, clumping factor, and staphylokinase, and exhibited different phage patterns. Their multiplica...

I provide estimates of the ultraviolet and visible light luminosity density at z 6 after accounting for the contribution from faint galaxies below the detection limit of deep HST and Spitzer surveys. I find that the rest-frame V-band luminosity density is a factor of 2Y3 below the ultraviolet luminosity density at z 6. This implies that the maximal age of the stellar population at z 6, for a Sa...

Staphylococcus aureus is a leading cause of ventricular assist device-related infections. This study evaluated the protective effect against S. aureus infection of active and passive immunization that targeted 3 proteins involved in bacterial attachment to a murine intra-aortic polyurethane patch. Active immunization of mice with a combination of the A domains of clumping factor A (ClfA), fibro...

Duthie (1954) reported that bound coagulase (clumping factor) of staphylococei is released from the surface of autolysing cells into the medium of old broth cultures. Rosenblum and Jackson (1957) noticed occasional alteration of bound coagulase and pigment production after storage of staphylococci for months to years. Decrease in bound coagulase activity of freshly isolated hospital strains of ...

A new immunoenzymatic assay (IEA) for the identification of Staphylococcus aureus strains of both human and animal origin was compared with rapid commercial kits. The sensitivities and specificities of the commercial kits varied from 90.2 to 96% and 90.8 to 93.7%, respectively. The IEA did not give any false-negative or false-positive results, while commercial kits gave high percentages of fals...

1. We investigated the relationships of seed size, dispersal mode and other species characteristics to interspecific variation in mean primary seed dispersal distances, mean annual seed production per unit basal area, and clumping of seed deposition among 41 tropical tree species on Barro Colorado Island, Panama. 2. A hierarchical Bayesian model incorporating interannual variation in seed produ...
