Hello Steemit Community!
My name is Andrea and I live in Venezuela, a medium-sized country in South America. Here, I work as a Bioanalyst. You might wonder what a bioanalyst does. Well, the answer is not simple at all, because we analyze everything from blood, tissues, urine, feces and body fluids.
So in my first post I bring you a selection of things that I have seen through the microscope while I work.
- Image: Uric acid crystals (400x).
- Sample: urine.
Your body produces uric acid when it breaks down purines —substances that are found naturally in your body—. Yeah, they can be beautiful (but painful sometimes).
- Image: Hematuria and pyuria (400x).
- Sample: urine.
- Image: Enterobius vermicularis eggs (400x)
- Method: Graham.
Also known commonly as pinworm is the most common intestinal parasite. It is a nematode that inhabits the human terminal ileum, colon and appendix.
- Image: leukocytes 400x.
- Sample: urine.
The presence of leukocytes in the urine could be a sign that you have an infection or an obstruction in the urinary tract or bladder (ouch!).
- Image: Squamous epithelial cells (400x).
- Yellow arrow: leukocyte.
- Sample: urine.
- Image: Hematuria (400x).
- Sample: urine.
- Image: Leukocytes and erythrocytes result of infection by Entamoeba histolytica (400x).
- Sample: feces.
Entamoeba histolytica is well recognized as a pathogenic ameba, associated with intestinal and extraintestinal infections.
- Image: Entamoeba coli cysts (400x).
- Sample: feces.
Entamoeba coli is generally considered nonpathogenic and reside in the large intestine of the human host. Tip: they can have between 1-8 nuclei.
- Image: Entamoeba histolytica/dispar cyst (400x).
- Sample: feces.
Infections caused by the Entamoeba histolytica/Entamoeba dispar complex are of cosmopolitan distribution. E. histolytica is known as the pathogenic specie of the complex, while E. dispar is considered commensal (non-pathogenic). They can be differentiated through Polymerase Chain Reaction (PCR)

Image: (yellow arrow) Babesia spp. merozoite found in the peripheral blood of a puppy (1000x).
Method: Buffy coat smear.
Sample: peripheral blood.
Babesia is a genus of protist parasites that cause babesiosis in animals and humans. Babesia has the ability to infect red blood cells, where it carries out its life cycle, resulting in lysis of red blood cells and therefore, severe anemia. Tip: They spread by certain ticks.
