All isolates were positive for metachromatic granules and none of these showed capsule or endospore formation (Table 3). Endospore staining was carried out by heating the air dried bacterial smear with malachite green for 5 min, followed by rinsing with water and counterstaining with safranin for 30s.
What is blood in the urine? Sometimes blood in the urine can be seen, but at other times it is present in such small quantities that it is not visible to the naked eye. A simple test can detect even tiny amounts of blood; it is a routine test, carried out at many medical examinations. Blood in the urine has various possible causes: 1. Urinary infection (cystitis) This is much the most common cause, particularly in young women. If the red urine coincides with symptoms of cystitis and disappears in a few days when the infection is treated, it is usually attributed to infection and no further tests are carried out. The other symptoms of cystitis are: 1  burning feeling on passing water. 2  feeling the need to pass urine more often. 3  feeling that the bladder has not been emptied. 4  sometimes a fever and feeling unwell.
No amount of blood in your urine is normal but that doesn't mean that it is caused by something dangerous. Hematuria can be microscopic (not seen except by laboratory studies) or macroscopic (can be seen by the naked eye). The most common reason for blood in the urine is a urinary tract infection or an enlarged prostate. The most worrisome reason for having blood in the urine is cancer of the bladder or kidney. Having smoked in the past, exposure to industrial chemicals, and advanced age can be risk factors for having cancer.
