Predators and Parasites
The black rat serves as prey to cats and owls in domestic settings. In less urban settings, rats are preyed upon by weasels, foxes, and coyotes. These predators have little effect on the control of the black rat population because black rats are agile and fast climbers. In addition to agility, the black rat also makes use of its keen sense of hearing to detect danger and quickly evade mammalian and avian predators. Rats serve as outstanding vectors for transmittance of diseases because they have the ability to carry bacteria and viruses in their systems. A few parasites that are common to rats include Streptococcus pneumoniae, Corynebacterium kutsheri, Bacillus piliformis, Pasteurella pneumotropica, and Streptobacillus moniliformis, to name a few. All of these bacteria are disease causing agents in humans. In some cases, these diseases are incurable.

Famous quotes containing the word parasites:
“Shy and proud men ... are more liable than any others to fall into the hands of parasites and creatures of low character. For in the intimacies which are formed by shy men, they do not choose, but are chosen.”
