According to Chandler’s index water containing 200-250 eggs should be considered as
**Core Concept**
Chandler's index is a method used to quantify the intensity of a urinary tract infection (UTI) by counting the number of bacteria per milliliter of urine. This index helps in determining the severity of the infection and guiding treatment decisions.
**Why the Correct Answer is Right**
Chandler's index is used to categorize the severity of UTIs based on the number of bacteria present in a urine sample. According to Chandler's index, a water containing 200-250 eggs or organisms per milliliter (mL) of urine is considered as 1+. This indicates a mild to moderate UTI, requiring appropriate antibiotic therapy. The organisms in question are likely to be **Escherichia coli (E. coli)**, a common cause of UTIs.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not relate to Chandler's index.
**Option B:** This option is incorrect as it does not correspond to any standard classification of UTIs based on Chandler's index.
**Option C:** This option is incorrect as it does not match the specified range of 200-250 organisms per mL.
**Clinical Pearl / High-Yield Fact**
It is essential to note that Chandler's index is a semi-quantitative method and may not accurately reflect the actual bacterial load in the urine. Therefore, it should be used in conjunction with other diagnostic methods, such as culture and sensitivity testing, to guide treatment decisions.
**Correct Answer: C.
