Lactulose is an osmotic laxative. This means it works by drawing water into the colon (i.e. it retains a lot of water with it) and hence softens your stool in cases of constipation. As you can imagine, this interferes with absorption of most drugs including antibiotics and even food. Neomycin is especially toxic to gut flora (as mentioned above) and if taken ...

Alan has covered some of it, but to add an illustration of the malabsorption piece of it, below left you can see a "normal" slice of small intestine, where the villi (finger like projections) are covered in enterocytes (the purple "bricks" along the border of the finger), which are responsible for the uptake of lipids (and their eventual "packaging") after ...

Coeliac disease is an immune disorder resulting from a reaction to ingested gluten (a protein found in wheat, barley and rye). It is associated with inflammation of the small intestine resulting in a generalised reduction in the capacity for digestion and absorption. According to this paper:
Celiac disease is associated with pancreatico-biliary disease. ...

So, certain antibiotics affect (and reduce) the ...

One textbook of microbiology suggests that the infectious dose of a specific strain of enterotoxigenic E. coli in adults would be $10^{8}$ cells. Keep in mind that infective dose will vary with species and strain, as well as the health, age and immune-status of the individual ingesting the bacteria. Children, elderly and ill people will generally be affected ...

The maximum temperature for E. coli to survive is dependent on the strain. E. coli from warm areas can easily survive 45 °C and more. The minimum number of E. coli to ingest in order to become ill is also dependent on the strain. Whether you become ill at all is also dependent on the strain. You harbor many billions of E. coli in your digestive tract without ...

The foods people in the developed world typically feed their carnivorous pets (including dogs and cats) are not made primarily from meat. Instead, they are made from plants, specifically grains, such as corn, rice and wheat.
In order to get our pets to eat foods that are so different from the meat-rich diets of their ancestors, we add flavors to the food.
