Salmonella is a bacterium that acts on the intestines, where it multiplies can enter the bloodstream and reaches other organs thus increasing the severity of the infection

Flies can transmit diseases because they are in constant contact with decaying materials, such as feces or dirt, carrying bacteria capable of causing some diseases, such as ringworm, berne, pinworm, trachoma and dysentery, for example. These diseases can be transmitted by domestic flies because the bacteria usually stick to their fur and can be released on the food or inside wounds on the skin when they come in direct contact with humans
