Spores of Bacillus megaterium, Bacillus cereus, and Bacillus subtilis were found to exhibit intrinsic paramagnetic properties as a result of the accumulation of manganese ions. All three Bacillus species displayed strong yet distinctive magnetic properties arising from differences in manganese quantity and valency. Manganese ions were found to accumulate both within the spore core as well as be...

Seventy five eye drops samples were collected from different pharmacies in Cairo, Egypt. Out of 75 tested samples, 58 (77.3%) are contaminated with bacterial growth when cultured on MYP medium. The bacterial count ranging from 1.0 CFU/ml to 6.0x10 CFU/ml. The microscopic examination indicated that 2 57 out of 133 isolates are Gram positive, spore forming bacilli. From 58 positive samples 32 sam...

PURPOSE We assessed the safety and efficacy of intravesical bacillus Calmette-Guerin instillations in steroid treated and immunocompromised patients. MATERIALS AND METHODS We retrospectively reviewed the charts of 697 patients treated with bacillus Calmette-Guerin instillations at our institution from 1991 to 2004. In 24 patients (3.5%) an underlying comorbidity directly affecting the immune ...

results the pcr approved the bacillus genus of the isolates. the strain of bacillus subtilis was identified using biochemical tests. 40 ºc and ph 11 are the optimum condition for maximum keratinase enzyme activity. objectives the aim of this study was the isolation of feather degrading bacillus spp.from a poultry waste and the optimization of conditions for the highest enzyme activity and feath...

Bacillus spore surface morphology was imaged with atomic force microscopy (AFM) to determine if characteristic surface features could be used to distinguish between four closely related species; Bacillus anthracis Sterne strain, Bacillus thuringiensis var. kurstaki, Bacillus cereus strain 569, and Bacillus globigii var. niger. AFM surface height images showed an irregular topography across the ...

Three species of Bacillus were evaluated as potential surrogates for Bacillus anthracis for determining the sporicidal activity of chlorination as commonly used in drinking water treatment. Spores of Bacillus thuringiensis subsp. israelensis were found to be an appropriate surrogate for spores of B. anthracis for use in chlorine inactivation studies.

Neighbor-joining, maximum-parsimony, minimum-evolution, maximum-likelihood and Bayesian trees constructed based on 16S rDNA sequences of 181 type strains of Bacillus species and related taxa manifested nine phylogenetic groups. The phylogenetic analysis showed that Bacillus was not a monophyletic group. B. subtilis was in Group 1. Group 4, 6 and 8 respectively consisted of thermophiles, halophi...
