Intro to Bacte Flashcards
Provided the initial evidence that some of themicrobes in dust and air have very high heat resistance and that particularly vigorous treatment is required to destroy them
John Tyndall
Discovered Streptomycin
Selman Waksman
Ability of a microbe to produce disease in an individual
Pathogenicity
The exhibition of a characteristic inherent resistance to specific antibiotics, heavy metals, or toxins.
Resistance profiles
Are organisms recognized to cause disease in healthy immuno-competent individuals as high percentage all the time
True pathogens
The first to use a lens to observe the smallest unit of
tissues he called “cells
Robert Hooke
The ability of an organism to utilize various carbon and nitrogen sources as nutritional substrates
when grown under specific environmental conditions.
Nutritional requirements
The microbial growth patterns on artificial media as observed when inspected with the unaided eye.
Examples include the size, texture, and pigmentation of bacterial colonies.
Macroscopic morphology
method for organizing microorganisms
into groups or taxa based on similar morphologic, physiologic, and genetic traits.
Classification
Microorganisms that are commonly found on or in body sites of healthy persons
Indigenous Microbial Biota
The profiles of microorganisms established by various serologic and immunologic methods to
determine relatedness among various microbial groups.
Antigenic properties
Harbors the organism but do not present
symptoms to the disease cause by these
organisms; can only transmit
Carriers
An infection that occurs as the result of medical
treatment or procedures
Iatrogenic Infection
Developed vaccines to prevent chicken cholera, anthrax,rabies, and swine erysipelas
Louis Pasteur
most basic of the taxonomic groups and can be defined as a collection of bacterial strains that share common physiologic and genetic features and differ notably from other microbial species.
Species
Heating liquids to 63 – 65°C for 30 minutes or 73 – 75°C for 15 seconds
Pasteurization
