Capnocytophaga canimorsus is a bacterium that can cause sepsis in people after being bitten by an animal.
Capnocytophaga canimorsus is a type of bacteria that exists in the mouths of healthy dogs and cats. It is shaped like a stem and is able to grow quickly under the right conditions. This bacterium can cause sepsis in people after an animal bite. This pathogen has a unique shape and outer layer and can cause serious illness if not treated quickly and effectively.
Capnocytophaga canimorsus is a type of bacteria that exists in the mouths of healthy dogs and cats.
This organism is a Gram-negative bacillus, which means it does not retain the colored mold used in a laboratory Gram stain test. This test helps to identify different types of bacteria. Gram-negative bacteria have an outer layer of fat that can make them resistant to antibiotics such as penicillin. Therefore, the treatment of diseases caused by this type of bacteria is much more difficult.
Those with limited or absent spleen function are more susceptible to Capnocytophaga canimorsus.
As the disease caused by capnocytophagus canimorsus can be transferred from animals to humans, it is known as zoonotic disease. This sepsis can be fatal for humans and can be misdiagnosed as symptoms often vary. Known signs of Capnocytophaga canimorsus sepsis are severe diarrhea, vomiting, abdominal pain, hypertension, and rapid heart rate. Patients may also experience high fever, organ failure, cardiac arrest, and coma.
Symptoms of capnocytophaga canimorsus in humans can include high fever.
People most susceptible to Capnocytophaga canimorsus infection are those with limited or absent spleen function. These asplenic patients may have their spleen removed due to trauma, illness, or genetic disorders, or in cases where spleen function worsens another medical condition. People who are immunocompromised due to illness or age are also more likely to be affected after a dog bite. As a result, anyone with a compromised immune system is advised not to have a dog.
Signs of Capnocytophaga canimorsus sepsis may include abdominal tenderness.
It is not always necessary for an animal bite to occur for Capnocytophaga canimorsus to be transmitted. In one case, a man with a history of having his spleen removed fell on his hands in a recent accident. He had small open wounds on his hands, which were later licked by a family member’s dog. This dog’s mouth harbored the bacteria, and the man later had sepsis. He was, however, able to recover after timely antibiotic treatment.
Victims of dog bites may benefit from blood and plasma transfusions in more severe cases of infection.
Although dog bite septicemia is relatively rare, it is a serious illness that can travel quickly through the bloodstream and affect the entire body. A number of different antibiotics, including doxycline and clindamycin, can be used in the treatment of capnocytophaga canimorsus sepsis. Patients may also benefit from blood and plasma transfusions in more severe cases of infection.
