Protists under the Microscope

Protists are any member of a group of diverse eukaryotic unicellular microscopic organisms. Protist typically refers to a eukaryote that is not a true animal, plant or fungus because it lacks a multicellular stage.

In order to view protists, a biological microscope is required with 400x magnification.

The image below of a protist was captured using a sample of pond water under the Zeiss Primostar HD digital microscope.

Tissue Biopsy under the Microscope

A biopsy is a way for a doctor to diagnose a disease. A sample of tissue or cells is removed from the patient by a doctor and sent to a pathologist to be examined under the microscope.

The following images were captured under a pathology microscope during a tissue biopsy.

Understanding Kidney Disease in Dogs

Kidney failure can cause of death in dogs and there are a number of different ways that kidney disease takes shape in dogs. Veterinarians use a microscope to test for some of the following problems in dogs:
  • Glomerular Disease: This is damage to the kidney filters and can be caused by infections such as Lyme disease or cancer.
  • Pyelonephritis: This is an infection of kidney tissues. If a veterinarian finds this infection, the bacteria that is causing the inflammation of kidney tissues can often be killed.
  • Neophrolithiasis: These are kidney stones. Unlike in humans, kidney stones actually do not typically cause dogs too much pain in the early stages.
  • Ureteral Obstruction with Hydronephrosis: This is a kidney blockage. If a dog has kidney stones and they fragment, they can cause a kidney blockage that will not allow urine to pass and the kidneys will swell and become damaged.
  • Tubulointerstitial Disease: This is damage to kidney tabules, often with an unknown cause. This type of kidney disease can only be determined by using a microscope to examine a kidney biopsy (see image below). 
  • Leptospirosis: This is a bacterial infection and can cause kidney disease along with organ problems in both people and dogs. Infection can be caused by contact with urine or other bodily fluids from the infected dog.
  • Toxins: These are medications, household chemicals, and even ordinary food like grapes or raisins. If your pet ingests toxins contact ASPCA Poison Control immediately.
  • Cancer: The good news is that kidney cancer is not common in dogs. The bad news is that treatment options for kidney cancer in dogs is quite limited. If only one kidney is affected it can be removed with a positive outcome. If the cancer is benign or has not spread the outcome can be good as well.
  • Amyloidosis: This is a protein issue with the kidneys where protein deposits replace normal tissue. 
  • Hereditary: Some purebred dogs have a higher rate of kidney disease than others. Additionally, some young dogs will fail to develop normal kidneys.
The image below is of a dog kidney and was captured using a veterinary lab microscope with a microscope camera.

Lily of the Valley under the Microscope

Convallaria is a genus of flowering plants and includes Lily of the Valley. This is a plant that is sweetly scented and highly poisonous and is native throughout the cool temperate Northern Hemisphere in Asia and Europe.

Convallaria majalis is an herbaceous perennial plant that forms extensive colonies by spreading underground stems and rhizomes.

The images below of Convallaria were captured using the Zeiss Primostar microscope.

Chromosomes under the Microscope

A chromosome is a DNA molecule with part or all of the genetic material of an organism. Chromosomes are only visible under a light microscope when the cell is undergoing the metaphase of cell division. During metaphase, when a chromosome is in its most condensed state, the X-shape structure is called a metaphase chromosome.

The images below were captured under the Zeiss Primostar microscope.
