Magnified World


When I looked through my first microscope at the age of eight, I didn't just see tiny swimming microbes from our bird bath. I saw the complete and total beauty of the world in the tiniest details. Here I post what we pass every day because we cannot see it. I hope you can see the beauty as I do.

Cryptosporidium (also known as “Crypto”)


Causal Agent and Life Cycle (above):
Many species of Cryptosporidium exist that infect humans and a wide range of animals. Although Cryptosporidium parvum and Cryptosporidium hominis (formerly known as C. parvum anthroponotic genotype or genotype 1) are the most prevalent species causing disease in humans, infections by C. felis, C. meleagridis, C. canis, and C. muris have also been reported.
Follow steps in graph above:
Sporulated oocysts, containing 4 sporozoites, are excreted by the infected host through feces and possibly other routes such as respiratory secretions . Transmission of Cryptosporidium parvum and C. hominis occurs mainly through contact with contaminated water (e.g., drinking or recreational water). Occasionally food sources, such as chicken salad, may serve as vehicles for transmission. Many outbreaks in the United States have occurred in waterparks, community swimming pools, and day care centers. Zoonotic and anthroponotic transmission of C. parvum and anthroponotic transmission of C. hominis occur through exposure to infected animals or exposure to water contaminated by feces of infected animals . Following ingestion (and possibly inhalation) by a suitable host , excystation  occurs. The sporozoites are released and parasitize epithelial cells (, ) of the gastrointestinal tract or other tissues such as the respiratory tract. In these cells, the parasites undergo asexual multiplication (schizogony or merogony) (, , ) and then sexual multiplication (gametogony) producing microgamonts (male)  and macrogamonts (female) . Upon fertilization of the macrogamonts by the microgametes (), oocysts (, ) develop that sporulate in the infected host. Two different types of oocysts are produced, the thick-walled, which is commonly excreted from the host , and the thin-walled oocyst , which is primarily involved in autoinfection. Oocysts are infective upon excretion, thus permitting direct and immediate fecal-oral transmission.Note that oocysts of Cyclospora cayetanensis, another important coccidian parasite, are unsporulated at the time of excretion and do not become infective until sporulation is completed. Refer to the life cycle of Cyclospora cayentanensis for further details.

Coronary Atherosclerosis
Many individuals who have been diagnosed with coronary atherosclerosis take medications to help hinder further progression of the disease. The class of drugs known as statins, which effectively reduce elevated cholesterol levels, have been especially useful in the battle against the condition and other forms of heart disease.
