Dark biotechnology is connected with bioterrorism and biological weapons. Biowarfare is the intentional use of microorganisms and toxins generally of microbial‚ plant or animal origin to produce disease and death in humans‚ livestock and crops (DaSilva‚ ****). The magnetism of bioweapons in biowarfare and bioterrorism is because of easy access to a disease-producing biological agents‚ low costs‚ low security and surveillance systems and easy transportation from one place to another. Furthermore‚

can imagine living in a world without antimicrobials. What is antimicrobial resistance? Antimicrobial resistance – also known as drug resistance – occurs when microorganisms such as bacteria‚ viruses‚ fungi and parasites change in ways that render the medications used to cure the infections they cause ineffective. When the microorganisms become resistant to most antimicrobials they are often referred to as “superbugs”. This is a major concern because a resistant infection may kill‚ can spread to

Introduction The development of dyes to stain microorganisms was a significant advance in microbiology. Stains serve purposes such as it differentiate microorganisms from their surrounding environment and it allows detailed observation of microbial structures at high magnification.

Microorganisms and other foreign substances are filtered from lymph by lymph nodes and from blood by the spleen. In addition‚ lymphocytes and other cells are capable of destroying microorganisms and other foreign substances.

By utilizing the Kirby-Bauer method‚ researchers and clinicians are able to determine the susceptibility of given microorganisms to different antibiotics and antimicrobials. While antibiotics specifically target bacteria‚ antimicrobials cast a wide net‚ nonspecifically targeting microorganisms and viruses.
