stains. Binary fission is a sexual reproduction in single-celled organisms during which one cell divides into two daughter cells.

The microbiology laboratory report for Mrs. Smith's urine culture lists eight antibiotics, three of which are followed by the letter "R." This means that: * these antibiotics are not effective in destroying that particular organism. *these antibiotics are effective in destroying that particular organism. *are likely to cause sensitivity or allergy in the patient. *Additional testing must be performed to determine the dosage of antibiotic necessary for successful treatment.

these antibiotics are not effective in destroying that particular organism. Sensitivity testing is reported to the provider in one of three categories for each antibiotic tested: S means that the pathogen is susceptible, or that the antibiotic is effective in destroying that particular organism. R means that the pathogen is resistant, or that the antibiotic is not effective in destroying that particular organism. I means intermediate, or that additional testing must be performed to determine the dosage of antibiotic necessary for successful treatment.
