Introduction: Chemical methods of control: Antimicrobial drugs‚ involves the use of chemicals to prevent and treat infectious diseases. Pasteur and others observed that infecting an animal with Pseudomonas aeruginosa protected the animal against Bacillus anthracis. Later‚ the word “antibiosis” (against life) for this inhibition and called the inhibiting substance “Antibiotic”. As researchers found out more and more about these chemicals they were able to discover that antibiotics are chemicals or

Abstract: The objective of the experiment is to learn how to use a microscope while viewing various types of bacteria cultures. Prepared slides are used to view bacterial cultures under a microscope that would normally be invisible to the naked eye. Bacterial shapes and arrangements or morphology are observed in prepared slides and fresh yogurt culture. Purpose: The experiment is meant to determine the shapes of bacteria under different magnifications when using a microscope; 10X‚ 40X‚ and 100X

Exercise 8-B Differential Staining Gram Staining and Acid Fast Staining Introduction: Differential Staining‚ one which facilitates differentiation of various elements in a specimen is a general term that can refer to a number of specific processes. Using multiple stains can better differentiate between different microorganisms or cellular components of a single organism. Gram’s Stain is a widely used method of staining bacteria as an aid to their identification. It was originally devised by Hans

Whilst foods such as ‘meat’ form relatively well -defined groups of raw materials‚ ‘fish’ constitutes a large range of types (some sources recognise over 20‚000 identified species)‚ caught over

Discussion The possible identity of the unknown organisms in the mixed culture was limited to bacteria that we had worked with previously in lab. Initially a Gram stain was conducted in order to distinguish the unknown bacterium as a Gram-positive and/or a Gram-negative organism (Lancaster and Bennett‚ 2012; Kellenberger‚ 2001). Based upon the results‚ both Gram-negative and Gram-positive bacteria were observed in the unknown mixed culture (Table 1 and Table 2; Kellenberger‚ 2001). In order
