A purified monoclonal antibody (MAb) which specifically reacts with Staphylococcus aureus glucosaminidase was obtained. This MAb was utilized to develop an immunoenzymatic assay for the identification of S. aureus strains. The sensitivity of this assay, based on the simultaneous detection of S. aureus glucosaminidase and protein A, was evaluated by analyzing a total of 196 strains, 26 of which ...

Objective(s) Staphylococcus aureus is a foremost source of numerous nosocomial and community acquired infections. Antibiotic therapy for vancomycin resistant S. aureus (VRSA) can not promise the eradication of infections. Since adhesion is the major route of infections, adhesin based vaccine could suppress S. aureus infections. Fibronectin binding protein A (FnBPA) and clumping factor A (ClfA)...

Context. Clumping is a common property of stellar winds and being incorporated to solution the radiative transfer equation coupled with kinetic equilibrium equations. However, in static hot model atmospheres, clumping its influence on temperature density structures have not been considered analysed at all date. This spite fact that can interpretation resulting spectra, as many inhomogeneities a...

The sigB gene of Staphylococcus aureus, coding for the alternate sigma factor B, has been deleted by allelic replacement mutagenesis. The mutant grew as well as the parent in vitro, although it was deficient in clumping factor, coagulase, and pigment. In two murine and one rat infection model the mutant showed no reduction in virulence.

Simple but realistic modeling of radiation transfer within heterogeneous canopy has been a challenging research question for decades and is critical for predicting ecological processes such as photosynthesis. The Markov model proposed by [Nilson, T., 1971. A theoretical analysis of the frequency of gaps in plant stands. Agric. Meteorol. 8, 25–38] is theoretically sound to meet this challenge. H...

In contrast to herbaceous canopies and forests, savannas are grassland ecosystems with sparsely distributed individual trees, so the canopy is spatially heterogeneous and open, whereas the woody cover in savannas, e.g., tree cover, adversely affects ecosystem structures and functions. Studies have shown that the dynamics of canopy structure are related to available water, climate, and human act...

Platelets may play a role in the pathogenesis of human cerebral malaria (CM), and they have been shown to induce clumping of Plasmodium falciparum-parasitized red blood cells (PRBCs) in vitro. Both thrombocytopenia and platelet-induced PRBC clumping are associated with severe malaria and, especially, with CM. In the present study, we investigated the occurrence of the clumping phenomenon in pat...

Energy efficient clumping formation of nodes in Mobile Ad-Hoc Networks (MANETs) is very important as nodes in MANETs typically activate unattended with a limited power source. Energy efficient clumping formation in MANET is one of the major issue because energy of one node in clumping may affect all other nodes and also effect on the life time of the Clumping Head.In this paper, propose a newal...
