micro-organisms where they can thrive and reproduce. For example‚ microorganisms thrive in human beings‚ animals‚ and regular objects which are used and touched such as water‚ table tops‚ doorknobs‚ and railings. The ‘portal of exit’ is a place of exit providing a way for a micro-organism to leave the reservoir. For example the micro-organism could leave the body through the nose by sneezing or as effectively by coughing through the mouth. Microorganisms carried away from the body by feces (when going to the

Antimicrobial resistance takes a place when a microorganism develops the ability to resist the action of an antimicrobial. (AVMA) In other words‚ the microorganism progress‚ ways to stay alive and reproduce in the presence of an antibiotic that used to prevent these actions. At this time‚ the process of resistance development is a very difficult process and researchers do not know for sure about what can make a resistance happen. (AVMA) Antimicrobials are spread through the food production systems

Nutrient Agar which is a growth medium used to culture microorganisms or small plants and Sabourand Dextrose Agar plates used to cultivate moulds and yeasts. The objective of it was to demonstrate that microbes are everywhere. We expected to find a variety of bacteria‚ moulds and yeasts. We were introduced to aseptic techniques as they help ensure that only certain microorganisms are present in the plate. These methods also guarantee that microorganisms do not escape from the specific petri dish‚ contaminating

When an agar plate is inoculated‚ why is the loop sterilized after the initial inoculation in put on? Ans: We use agar plate to inoculate microbes by zipping the loop on the agar several times. We streak on the agar plate four time‚ propose is to isolate the unknown bacteria. Therefore‚ the first time to streak on the plate‚ there are

A pathogen is a tiny non-visible disease causing microorganism such as Bacteria‚ Virus and Fungus. Both the scientific name and common name for Actinomycosis is Actinomycosis. The pathogens that cause Actinomycosis are from a species of Actinomyces‚ most commonly known as Actinomyces Israelii and Actinomyces Gerencseriae. The species of Actinomyces are an Actinobacteria class of Bacteria. The pathogens are endogenous‚ meaning the bacteria originate from inside the body‚ making them not liable to

how it can be treated‚ to knowing the correct microorganism to be used for producing certain foods or antibiotics‚ to biological warfare. Their uses are infinite as are their abilities to develop and adjust to altering environments. That is why it is so significant to be competent to identify microorganisms. This study was conducted by applying techniques and experiments cultured in microbiology lab for the identification of the unknown microorganism. Introduction: Identification of bacteria is significant

answer this question‚ we were required to complete three bacterial labs that helped us to understand what microorganisms are and how to identify and classify them. Thus‚ the main purpose of this project is to identify our unknown microorganisms‚ more specifically‚ our unknown bacteria. There are many ways to distinguish and classify bacteria. You can distinguish bacteria from other microorganisms by its size. Bacteria are around one micrometer and yeast is 4-40 micrometer
