There are maggots in the kitchen, and mould and damp throughout the house, including the children's bedrooms.

One of them, for example, is responsible for the pigmentation of the maggots' teeth, while another is responsible for the formation of the striped pattern on the fly's abdomen.

Patient wounds routinely crawling with maggots because health care facilities have no access to soap, gauze, disinfectant and running water.

The infestation cycle continues when the maggots emerge 10 days later, drop from the fruit and burrow two to three centimeters into the dirt to pupate.

Chicago Police and the FBI are investigating who contaminated a breakfast buffet served to delegates at the Democratic National Convention with maggots.
