Abstract – The Purpose of this exercise is to gain experience in bacterial morphologies in prepared wet-mounted slides and interpreting the findings of bacteria through direct and indirect staining technique. Hypothesis – The experiment will allow for further insight into stained organisms, allowing extended contrast, differentiating shape and structure through …

Outcome 1 Understand the causes of infection 1. Identify the difference between bacteria, viruses, fungi and parasites? The difference between bacteria, viruses, fungi and parasites is: Bacteria Bacteria is a single celled organism, bacteria have evolved to thrive in almost any environment and can be found in almost any substance/surface …

1. Identify the differences between bacteria, viruses, fungi and parasites. Bacteria is something that we need some of, it needs a warmth, moisture, time and food in order to multiply, which in the right conditions they multiply quickly. Viruses need a living host in order to survive, they don’t respond …

A. Enriched, complex and synthetic media are microbiological media. Enriched media is a medium containing growth factors. Complex media is composed of unknown quantities of proteins and extracts. Synthetic media is composed of a known quantity of chemicals used. They provide different environments for bacterial growth. 1. Enriched media can …

The difference between bacteria, viruses, fungi and parasites are: Bacteria are single celled organisms that can rapidly multiple themselves every 10 minutes up to 10 times each bacterial cell, but they do not live or reproduce in a human cell. When threatened they will make a copy of their DNA …

Purpose: The purpose of this experiment is to gain knowledge of the functions and operations of the compound light microscope and an immersion oil lens by observing prepared slides of various bacteria and blood slides. We are also learning to indentify and observe the various shapes and characteristics of bacteria, …

A plan to minimize/reduce these issues in the future shall be presented with explanations regarding effectiveness. The Problems with Antibiotic-Resistant Bacteria Antibiotic-Resistance is the ability of bacteria and other microorganisms …

To help the prevention of infection spreading is by knowing the method of washing your hand because we carry most bacteria sue to the open air that we come in contact with. For example we use are hands to shake hands with someone holding or touching objects. When you are …

Conjugation is a natural occurring process that involves the transfer of DNA from one cell into another through a physical connection between the cells. In the following experiment, two strains of Escherichia coli bacterial cells (donor F’lac+strs and recipient F-lac-strr) underwent conjugation to produce a transconjugant strain (F’lac+strr). MAC plates …

Introduction The cells of beetroot contain a pigment called betalain in their vacuoles. It is kept inside the cells by the membranes. If these membranes are damaged, then the betalain leaks out. The amount that leaks out can be assessed, as the leaked out pigment will color the water surrounding …
