Question

Question 7 (1 point) Saved After steaking a sheep blood agar plate with a throat swab, the purpose of stabbing the inoculum inot the agar (or placing in an anaerobic jar) is to: O provide reduced oxgyen tension for better growth obtain isolated colonies of respiratory flora clean off the inoculating loop enhance the beta-hemolytic activity of the pathogen

Answer 1

Question 7

Choice “A”: Provide reduced oxygen tension for better growth.

• Explanation: Anaerobic jar means that a jar provide space to place the sheep blood agar plates and it contains a lamp inside it.
• The purpose of the jar is to use up majority of the oxygen in the lamp, so that the organism can which belongs to anerobic category can grow well.
• Throat swab such as Streptococci is usually prefer reduced oxygen for its better growth. So that the inoculated throat swab can placed in the candle jar and provide them carbon dioxide for their better growth by taking up all the oxygen by the candle.
• Remaining choices are not related to the stament. So that answer is choice “A”
