Question
Chapter 19.5, Problem 1EQ
Summary Introduction
To determine: The hypothesis proposed by Lederberg and Tatum experiment.
Introduction: The experiment performed by Lederberg and Tatum was conducted to understand the mechanism of transformation in bacteria. The experiment was later continued by Davis to finally prove that direct contact is pre-requisite for conjugation to occur.

QUESTION 4The ability of a bacterial isolate to perform hemolysis can be regarded as an indication ofpotential pathogenicity. Briefly describe how you would test for this trait.
QUESTION 5You are asked to recommend an antibiotic to treat this infection in an animal. Describe amethod which will allow you to make this recommendation.
