- 5 years old child came to emergency complaining of headache and fever (39.4°C). On examination, he has Confusion, difficulty in wake, Neck stiffness. sample sent to lab for further investigations. Gram stain show Gram-positive, spherical bacteria, alpha-hemolytic What are the tests to be done to complete identification?A food sample with an unknown number of contaminating bacteria was serially diluted to 10-6. A volume of 0.1 mL (100 μL) of the dilutions was plated. The 10-6 plate contained 96 colonies. What was the original microbial concentration?Abigail did not dry the top of her agar plate and stored it top up. Now she wants to count colonies but there is a smear over the entire plate. She was working with E. coli. Why does she have a smear?

(Gram Stain and Growth Result is already done) Possible Tests (pick 2 that would help know the unknown bacteria) Gram stain morphology & arrangement color and growth characteristics on agar 37C, 30C and 25C (room temp) CAMP test starch hydrolysis test bacitracin susceptibility test glucose, lactose, sucrose, maltose fermentation tests methyl red/MR test Mannitol MacConkey Phenol Red Vogues-Proskauer/VP test citrate utilization test urea hydrolysis test phenylalanine deaminase test SIM test (Sulfide/Indole/Motility) Nitrate reduction test Oxidase test Catalase test
- In product testing, no colonies appeared. Interpretation: Rationale:Describe characteristics of Streptococcus Agalactiae in the Agar: (How does colonies look like (color) and explain does it grow on that agar. (Don't have to write the incubation period) ~ Only describe how would it look like on the Agar: Blood Agar (Aerobic) MacConkey EMB PEA Mannitol Salt Agar Chocolate Agar Nutrient AgarThe health center cultured the throat swab and after doing a gram stain observed the picture to the right. The size bar measures 10mm with a ruler and the observed organisms have a diameter that measures 0.8 mm. What is the actual size of these organisms?
