Pictures of Parasites
Ancylostoma duodendal (human hookworm)
Adults of hookworm infections will lay eggs like the one above in the intestinal tract of patients where they suck their blood intensively to the point of serious anemia and weakness.

Charcot-Leyden crystals
Charcot-Leyden crystals are by-products of the breakdown of certain human white blood cells as a result of their destruction by certain parasites such as Entamoeba
histolytica . Their recovery in fecal samples thus indicatesthe presence of certain parasites

Cryptosporidum parvum
Cryptosporidium parvum is perhaps the most common new parasitic disease in the USA. Infection occurs from drinkingwater contaminated with calf fecal sources. The tap water ofnearly 1/5 of all U.S. homes include infective stages of
cryptosporidium as well as Giardia. Symptoms may be present in intestinal as well as extra-intestinal sites and may include fatigue and allergies.

Taenia solium
The recovery of eggs of the human/swine tapeworm Taenia solium indicates the presence of the ten-foot long adults inthe intestine. When the immature cysts are present in other organ systems, they often invade the brain and sense organs causing neurocysticerocosis (damage to the central nervous system).

Large number of white blood cells
The presence of WBC's indicate an attempt to contain the operation of infective processes or punishing toxilogical factors. We often see granulocytes and sometyimes lymphocytes. HIV patients often have a high number of WBC'sand low levels of benefical bacteria.
