Pasteurella multocida. Light micrograph of a colony of the bacteria Pasteurella multocida. It is a bacteria that causes haemorrhagic septicaemia and other infections in animals and humans. Such bacteria are occasionally found in wounds to humans caused by cats and dogs, having originated from the animals' mouths. The presence of Pasteurella may prevent the wound from healing; antibiotics such as penicillin may offer treatment. Pasteurella sp. has also been identified in the sputum of persons with chronic bronchial disease, but the significance of its presence here is uncertain. Darkfield lighting.
