Nutritive stresses

It is well established that overcrowding, poor nutrition, stress and general poor health increase the risk of contracting tuberculosis. The conditions of the poor in the large cities during the industrial revolution in Britain were ideal for development of tuberculosis, as recorded by Friedrich Engels in his book Conditions of the British Working Classes.

Balantidium coli is the largest of the protozoans that infect humans. The trophozoite form is covered with cilia, which impart mobility. Infection is acquired through the ingestion of cyst-contaminated soil, food, or water. The trophozoite causes superficial necrosis or deep ulceration in the mucosa and submucosa of the large intestine. Otherwise healthy persons commonly exhibit nausea, vomiting, abdominal pain, and diarrhea, whereas debilitated or nutritionally stressed patients may develop severe dysentery.

Kuna and Kapp (1981) found decreased fetal weight after exposure to 50 ppm and demonstrated that there was only 1 exencephalic rat in a group of 151 pups examined after in utero exposure to 500 ppm benzene. In the same study, of 98 pups examined for skeletal effects after in utero exposures of 500 ppm, only 1 pup had angulated ribs and 2 others had nonsequential ossification of the forefeet. These anomalies were not statistically significant and may have resulted from maternal nutritional stress.
