DANGER ON PAWS - His case is relayed by many American media. A 54-year-old American woman had her legs and hands amputated after her dog licked her and passed on a bacterium called Capnocytophaga canimorsus. In 2018, we interviewed Professor Geneviève Héry-Arnaud, a bacteriologist at the University Hospital of Brest, on the subject.

The lick could have been fatal to him. He earned him amputation of both legs and both hands. In May, US media reports, a 54-year-old woman had to be treated urgently in Ohio after her dog, a German Shepherd puppy, licked an injury. First of all, having a high fever, she soon felt sharp pains in the extremities of her limbs. The doctors diagnosed him with sepsis, a serious infection with liver and kidney failure caused by a bacteria in his companion's saliva: Capnocytophaga canimorsus.

At the end of 2016, another case had attracted the attention of various French doctors. The patient in question had entered emergency department of the Brest CHRU and had all the signs of meningitis, including necrosis of the limbs. The inflammation was also caused by the saliva of a dog. He had to have his thumb and index finger amputated. Following the diagnosis of this patient, Professor Geneviève Héry-Arnaud, of the laboratory of bacteriology and virology of the University Hospital of Brest and several of his colleagues had decided to study more closely the bacterium Capnocytophaga canimorsus. Their work was published in the journal Médecines et Maladies Infectieuses on June 6, 2018.

  • 60% of cases have weakened immune systems before infection

"Almost 90% of the cases that have been reported are due to dog bites, introduces Geneviève Héry-Arnaud, joined by telephone, but this is mainly because they are the ones who bite the most." But, do not panic, not everyone is vulnerable. "The main factor of contamination is the victim and his immune status.In 60% of cases, there is a state of immuno-depression, says the bacteriologist, that is to say that these kinds of infections Very serious cases occur preferentially in people who are weakened. " Splenectomized persons, that is to say whose spleen has been removed, are the most fragile, the organ being essential for the immune defense. "In risk factors, we also find cirrhosis or chronic ethylism, and often tobacco.It often goes together besides, complete the specialist.And then there are people with diabetes or sub-corticoids.

Some popular beliefs can also endanger those who carry it. "There is a popular saying that says 'dog saliva is worth a doctor', so some people think that there are virtues to saliva and that are treated with dog saliva, we had a case like that where the the patient had had a neurosurgery operation, he had a beautiful scar in his back and he was being licked conscientiously by his dog, believing that it would help with healing, so he ended up with meningitis because of the bacteria, "says Geneviève Héry-Arnaud.

It does not mean that you must immediately get rid of his dog, she says. "If you have 'normal' relationships with your animals, there is no danger." Especially since despite the presence of bacteria in the mouths of cats and dogs, its most virulent forms, which can trigger an infection, have not necessarily developed.

  • A number of cases largely underestimated

To date, 500 cases of Capnocytophaga canimorsus infections have been reported since 1976 worldwide. In France, three people died between February 2017 and April 2018. But according to Professor Geneviève Héry-Arnaud, these figures are largely underestimated. "We do not necessarily think of writing a case report, so to report the case, each time we meet one, so finally, as there is no observatory as Pastor for the meningococcus or the Pity Salpetriere for tuberculosis, there is not really any surveillance, I think that for a case published in the world, there is the double that is not. " When analyzing patients who may have an attack on the bacteria, it is also not obvious to highlight.
