Bacterial endospores are highly resistant structures that allow survival for long periods of time in adverse environments. The spore-forming Gram-positive bacterium Bacillus subtilis synthesizes a coat around the endospore during development composed of several assembled polypeptides. The role of these components of the spore coat remains unclear; however, some of them appear to be enzymes poss...

Escherichia coli bacteria are that susceptible to contaminating chicken meat. Bacterial contamination in meat generally comes from the room, equipment or table where is abattoir, as well water used during slaughtering process processing of The impact if people consume contaminated with general symptoms abdominal pain, diarrhea, vomiting, fever and typhus.

INTRODUCTION People infected by Human Immunodeficiency Virus (HIV) are susceptible to develop severe bacterial infections. We set out to determine the frequency and the sensitivity to antibiotics of enterobaceriaceae isolated from urine and feces of HIV-infected persons. METHODS Urine and feces samples were collected from HIV-infected patients of the Centre de Traitement Ambulatoire de Kabind...

The area of nanotechnology encompasses the synthesis of nanoscale materials, the understanding and the utilization of their physicochemical and optoelectronic properties, and the organization of nanoscale structures into predefined superstructures. The development of biologically inspired experimental processes for the synthesis of nanoparticles is evolving into an important branch of nanotechn...
