The Gut Microbiome: Is Fecal Matter Microbial Composition A Proxy For Intestinal Microbial Composition In Studies Of The Microbiome, Enique Reyes Jan 2019

The Gut Microbiome: Is Fecal Matter Microbial Composition A Proxy For Intestinal Microbial Composition In Studies Of The Microbiome, Enique Reyes

All Master's Theses

As many health phenomena seem to be affected directly and indirectly by the microbiome, gut microbiome research has increased in the last decade. Issues such as allergies, cancer, obesity, and other health complications have been shown to be influenced by the microbiome. Most of gut microbiome research is done by collecting and sequencing the DNA of the microbiome of the fecal matter from model organisms or human subjects. Studies that use this method of sample collection and analysis assume that fecal matter microbiomes are similar to intestinal microbiomes, and that it can be used as a proxy. At present, no …


Histochemical Investigation On The Distribution And Localization Of Digestive Enzymes In The Alimentary Canal Of The Caddis Fly Larvae, Brachycentrus Occidentalis Banks, Walter B. Hollow Aug 1971

Histochemical Investigation On The Distribution And Localization Of Digestive Enzymes In The Alimentary Canal Of The Caddis Fly Larvae, Brachycentrus Occidentalis Banks, Walter B. Hollow

All Master's Theses

A histochemical study of the digestive enzymes of Brachycentrus occidentalis Banks showed that the insect contains the enzymes necessary to utilize the major foods, viz., carbohydrates, lipids and proteins. There appears to be a correlation between the types of digestive enzymes found and the type of food eaten by the larvae. Values of pH for extracts from the different parts of the digestive system were: foregut, 7.6-8.4, midgut, 7.6-8.4, and hindgut, 7.0-7.6. Living micro-organisms in the gut lumen was also shown.


Effect Of Temperature Upon Reproduction And Cyclic Development Of Culture Forms Of Trypanosoma Avium, Richard Michael Oliver Aug 1967

Effect Of Temperature Upon Reproduction And Cyclic Development Of Culture Forms Of Trypanosoma Avium, Richard Michael Oliver

All Master's Theses

Though much research has been done on the parasitic protozoans of the suborder Trypanosomatina in general, particularly those pathogenic trypanosomes which infect mammals, relatively little research has been directed toward those forms which infect birds.
