There are many protozoal parasites out there that are transferred to humans mostly through fecal contaminated water. Yet another great reason to have a reverse osmosis water system. Here’s the list. Links direct you to more specifics. I’ve tried to focus on the most important and pertinent ones for North America and Europe for now. I’ll fill in the blanks as I have time.
Yeast cells divide every 24 hours and feed on simple sugars. Hormonal changes, antibiotic use, illness, stress, parasite infections and other factors can upset the vaginal ecosystem, causing yeast cells to grow more rapidly than normal.
I often see chiggers as an external parasite that is really, really itchy. The term chigger is a common name for the six-legged larva of any of several blood-sucking mites. Chiggers normally feed on the blood of animal hosts such as birds, reptiles, and small mammals, but they also bite humans. People who go hiking, camping, or simply playing in the backyard or park can pick up a case of chiggers. Chiggers cause tiny red itchy bumps on the skin. These bites can be differentiated from flea bites because flea bites usually make a tight grouping of 3-5 bites.
Mange is NOT passed from animals to humans and neither are human head or public lice. Each animal has its own species of lice that likes to just stay on that particular species. For example, chicken lice love the fact that a chicken’s body temperature is about 105 degrees. So, if they would get onto a human, it would be too cold for them.
Keeping the area scrubbed removes the fungal food source (the dead skin cells) and applying iodine to it can help. I usually dispense a Chlorhexiderm shampoo which you can also purchase at most pharmacies these days. Also keeping your immune system and that of your pet healthy with good high-quality foods helps immensely.
The immature eggs are discharged from human feces and reach fresh water, hatching after 3-7 weeks and forming miracidia. Upon contact with host snails, the miracidia penetrate the soft tissues and form sporocysts, first- and second-generation rediae, and, lastly, cercariae. The cercariae encyst on various plants such as water caltrop, water chestnut, lotus (on the roots), water bamboo, and other aquatic vegetables. Humans are infected by consuming these raw vegetables. In the human duodenum, the metacercariae attach to the walls and become adult worms in approximately 3 months.
