- Factors which can influence antibiotic susceptibility testing (size of zone inhibition) are_________________.In sterilization, which among the supplies, instruments, glassware, etc. under the list of materials can be sterilized using either or both equipment below? List them down. For "autoclaving" For Dry heat oven Can be sterilized only sterilization with either Materials: 200-ml Erlenmeyer flask Stove 500-ml Erlenmeyer flask Autoclave 10-ml graduated cylinder Analytical balance 100-ml graduated cylinder pH meter Spatula Stirring rod 100-ml beaker Test tubes Distilled water Petri dish Stirring rod Alcohol lamp Glass dropperThe best medium for using antibiotic susceptibility testing is _________________, the reason why this medium is preferred is ________________.
- make the test principle, materials required for the analysis, sample preparation, test procedure, indication of a positive result, complications/interferences, for nitrous acid test.After running a novobiocin sensitivity test, the zone of inhibition diameter measured 14 mm for one of the staphylococcus organisms. Based on this diameter, the organism is presumed to be__________The table below summarizes the results for Lead-sulfide test. Provide the correct remarks from the results if Negative for Lead-sulfide test or Positive for the Lead sulfide test and it's either Negative for -SH or Positive for -SH
- A nurse reconstituted a vial of 750 mg Cefuroxime Sodium Powder for Injection with 6mL of sterile water for injection. The reconstituted solution was dark amber-colored solution. The package insert states that solution colors range from clear to yellow depending on concentration, diluent, and storage conditions. The nurse was then hesitant to give the patient the solution due to its unusual dark color. Five portions were taken from a batch of cefuroxime sodium. Prior to testing in the instrument, each part was subjected to one of the following conditions: Conditions Specifications Temperature Portion 1: 8°C ± 2°C Portion 2: 30°C ± 2°C Portion 3: 40°C ± 2°C Light Portion 4: Kept in the dark Portion 5: Exposed to direct sunlight 1. Which form of the product – the powder for injection, the reconstituted product, or both – will you subject to the following conditions? Why do you think these forms can best address the problem?Reverse isolation may be used for a person receiving _______________.‘Practical techniques used to identify unknown microorganisms’ You should include the types of tests you would use and how to interpret the results. You do not have to include a step-by-step guide to each of the practical techniques, but rather information could include background, reasoning and/or expected results.

At a dilution factor of, UHT-pasteurized milk sample X yielded the following bacterial colony counts when spread-plated in quadruplicates: 23, 20, 35, and 41 CFU/plate. As a result, the milk sample will pass laboratory standards if the total microbial limit is set to "not to exceed 30,000 CFU/mL of milk sample."
