Pouring agar plates
zhlédnutí 7KPřed 5 lety
Welcome to our suite of NUI Galway Microbiology teaching videos. We hope that they will guide you in performing your experiments in a scientific and safe manner. This video gives an overview of how to pour agar plates using aseptic technique.
Isolation of single bacterial colonies
zhlédnutí 9KPřed 5 lety
Welcome to our suite of NUI Galway Microbiology teaching videos. We hope that they will guide you in performing your experiments in a scientific and safe manner. This video describes how to perform a “3 way streak”. This is one of the most fundamental techniques that you should master as a microbiologist. It leads to isolated bacterial colonies that are necessary in applications such as bacteri...
KOH string test for bacterial characterisation
zhlédnutí 10KPřed 5 lety
Welcome to our suite of NUI Galway Microbiology teaching videos. We hope that they will guide you in performing your experiments in a scientific and safe manner. This video describes how to perform a KOH string test. This test is a valuable adjunct to the Gram stain, and will help to determine if an organism is Gram positive or Gram negative.
Preparation of a bacterial smear for staining
zhlédnutí 26KPřed 5 lety
Welcome to our suite of NUI Galway Microbiology teaching videos. We hope that they will guide you in performing your experiments in a scientific and safe manner. This video details how to perform a bacterial smear. This is a critical part of any bacterial staining technique. The smear is heat fixed to ensure the bacterial cells stick to the microscope slide and to kill cells on the slide.
Simple bacterial staining technique
zhlédnutí 11KPřed 5 lety
Welcome to our suite of NUI Galway Microbiology teaching videos. We hope that they will guide you in performing your experiments in a scientific and safe manner. This video describes how to perform a simple stain. When viewed under a microscope, bacteria are opaque and almost invisible to the naked eye. In order to study their morphology, cells are stained with different dyes. The simple dye us...
Gram stain technique
zhlédnutí 8KPřed 5 lety
Welcome to our suite of NUI Galway Microbiology teaching videos. We hope that they will guide you in performing your experiments in a scientific and safe manner. This video describes how to perform the most widely used differential staining technique in microbiology: the Gram stain. Developed by Dr Christian Gram in 1884, it categorises bacteria as Gram positive or Gram negative. In addition, t...
Using the compound light microscope

Welcome to our suite of NUI Galway Microbiology teaching videos. We hope that they will guide you in performing your experiments in a scientific and safe manner. This video demonstrate how to use a compound light microscope to investigate the morphology of bacterial cells. In this video we show how to use the 100X oil immersion lens.
Serial dilution of bacterial culture
zhlédnutí 6KPřed 5 lety
Welcome to our suite of NUI Galway Microbiology teaching videos. We hope that they will guide you in performing your experiments in a scientific and safe manner. This video describes how to perform a serial dilution of bacteria, a technique used routinely in microbiology to estimate the number of colonies in a bacterial sample. Colonies are cultured from ten-fold serial dilutions of the sample ...
Enumeration of bacteria on agar
zhlédnutí 8KPřed 5 lety
Welcome to our suite of NUI Galway Microbiology teaching videos. We hope that they will guide you in performing your experiments in a scientific and safe manner. This video describes how to count the number of colonies arising from a spread plate technique. When a sample is serially diluted and plated onto agar, single isolated bacteria grow to form visible, isolated colonies. The number of col...
Spread plating of bacteria on agar
zhlédnutí 18KPřed 5 lety
Welcome to our suite of NUI Galway Microbiology teaching videos. We hope that they will guide you in performing your experiments in a scientific and safe manner. This video describes how to perform a spread plate technique, another method routinely used in microbiology laboratories. A liquid sample is plated onto a general purpose agar to enable the bacteria in the sample to be counted or isola...
