Plasmodium falciparum is the most dangerous form of malaria. The parasites can be seen as numerous little red dots in.this thick blood smear scattered around the white blood cells. The red blood cells have been destroyed by tge Giemsa stain, and can therefore not be seen.  Malaria is spread by mosquitoes. Millions of people are killed by malaria every year.

Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens.  Depth of focus is extremely shallow (just a few microns).  Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Abundant meningococci bacteria observed, with a notably absence of white blood cells in the spinal fluid from a critically ill meningitis patient. Meningococcal meningitis is the term used to describe a bacterial form of meningitis caused by Neisseria meningitidis. This form of meningitis is associated with high morbidity and mortality. \nSometimes the bacteria spread to people who have had close or lengthy contact with a patient with meningococcal disease. Those at increased risk of getting sick include: People in the same household, roommates and anyone with direct contact with the patient’s oral secretions, such as a kissing partner
