Ebola virus

Single filamentous Ebola virus particle, scanning electron microscopy (SEM), digitally-colorized. Ebola is a rare but deadly disease caused by infection with one of the Ebola virus species which belong to the Filoviridae family. Ebola can cause disease in humans and nonhuman primates. Infection is through direct contact with infected blood / body fluids, objects and primates. Symptoms may include fever, severe headache, muscle pain, weakness, fatigue, diarrhea, vomiting, abdominal pain and unexplained hemorrhage.

Candida parapsilosis

Candida parapsilosis or Candida yeast. Magnification 1400, scanning electron microscopy. Candida species are part of the normal flora of mucous membranes of the mouth, gut and vagina. They are opportunistic fungi which may grow and become invasive if the host is immunologically compromised; steroid therapy, malnutrition, diabetes and antibiotic suppression of the normal bacterial flora are predisposing factors. Candida parapsilosis is an important non-albicans species which infects hospitalized patients. Biofilm production by the yeast plays an important role in C. parapsilosis outbreaks.
