Escherichia coli

 E. coli (Escherichia coli) is a type of Bacteria that normally lives in your intestines. It’s also found in the gut of some animals.


Most types of E. coli are harmless and even help keep your digestive tract healthy. But some strains can cause diarrhea if you eat contaminated food or drink fouled water.


While many of us associate E. coli with food poisoning, you can also get pneumonia and urinary tract infections from different types of the bacteria. In fact, 75 to 95% of urinary tract infections are caused by E. coli.


Some versions of E. coli make you sick by making a toxin called Shiga. This toxin damages the lining of your intestine. The strains of E. coli that make the toxin are sometimes called STEC, which is short for “Shiga toxin-producing E. coli ”


One especially bad strain,  can make you very sick. It causes abdominal cramps, vomiting, and bloody diarrhea. It is the leading cause of acute kidney failure in children. It can also cause life-threatening symptoms such as:

Adult kidney failure

Fever

Bleeding

Confusion

Seizures

Rericulocyte Staining process

  Rericulocyte Staining process A reticulocyte stain is a technique a day of Highlight RNA in reticulocytes, A type oc Immuture RBC. This stain commonly use in Hematology department in pathology lab. Edta sample mixed with Reticulocyte staining Solution(Methylene blue) ↓ After Mixed incubate at room temperature. ↓ Prepare   a blood smears ↓ Wait A slide Air-dried the smear ↓ Examined under microscope ↓ The number of reticulocyte count in the patient blood sample is countyed and expressed a percentage   The stain show the RNA in reticulocytes as a blue colour against the pink colour of the rest of the cell. The pattern of the blue colour indicatye the stage of the reticulocyte A hight reticulocyte count can indicate that immutur red blood cells are not surviving longenough, & that the bone marrow needs to increase production. The reticulocyte count is an important role of monitoring of red blood cellssurvival & formation activity o...
