If the bacteria contain catalase the mixture bubbles as the hydrogen peroxide decomposes into water and oxygen In the clinic the catalase test helps distinguish catalase positive Staphylococci from catalase negative Streptococcus which are both Gram positive cocci H influenzae and H haemolyticus will grow in the hemolytic zone of S aureus on blood agar plates the hemolysis of cells by S aureus releases factor V which is needed for its growth H influenza and H haemolyticus will not grow outside the hemolytic zone of S aureus due to the lack of nutrients such as V factor in these areas
This paper reviewed core concepts of interpreting bacterial culture results including timing of cultures common culture sites potential for contamination interpreting the Gram stain role of rapid diagnostic tests conventional antibiotic susceptibility testing and automated testing There are a lot of different types of agar plates used in the microbiology lab but the three most common are sheep blood agar chocolate and MacConkey MacConkey agar is selective for G bacilli and further differentiates G bacilli through lactose fermentation On MacConkey agar lactose fermenting bacteria will turn a bright pink color

agar plates On agar media containing blood it exhibits glistening haemolytic colonies and develops an average diameter of 2 0mm in 1 to 2 days Colonies equally grow well on MacConkey agar They are oxidase positive and motile by peritrichous flagella They are also nitrate and urease positive usually within 4hr which is a MacConkey agar MAC is a bacterial culture medium named after bacteriologist Alfred T MacConkey 1861 1931 MacConkey agar is a selective and differentiating agar that only grows gram negative bacterial species it can further differentiate the gram negative organisms based on their lactose metabolism 1 The selective and
Catalase neutralizes the bactericidal effects of hydrogen peroxide 13 and its concentration in bacteria has been correlated with pathogenicity 8 Enzyme based tests play a crucial part in the identification of bacteria Clinical significance They are the cause of invasive neonatal infections Neonatal infections present as two different clinical entities early onset neonatal disease characterized by sepsis and pneumonia within the first 7 days of life late onset disease with meningitis and sepsis between 7 days and 3 month of age
