Pasteurella septica

Pasteurella septica is a bacterial species that belongs to the Pasteurellaceae family. It is a Gram-negative, aerobic, non-motile, and coccobacillus organism. This bacterium is known to cause various infections in both humans and animals.

Overview[edit | edit source]

Pasteurella septica is a part of the normal flora in the respiratory tract of many animals, including cats and dogs. It is often associated with animal bites and can cause infections in humans if transmitted through a bite or scratch. The bacterium can cause a range of diseases, from mild skin infections to more serious conditions such as sepsis or meningitis.

Infections in Humans[edit | edit source]

In humans, Pasteurella septica is most commonly associated with wound infections following an animal bite or scratch. Symptoms of an infection can include redness, swelling, and pain at the site of the wound, as well as fever and chills. If left untreated, the infection can spread to other parts of the body and cause more serious conditions such as cellulitis, osteomyelitis, septic arthritis, and pneumonia.

Infections in Animals[edit | edit source]

In animals, Pasteurella septica can cause a variety of diseases, including pasteurellosis, which is a serious respiratory disease in rabbits and other small mammals. It can also cause hemorrhagic septicemia in cattle and buffalo, and fowl cholera in poultry.

Treatment[edit | edit source]

Treatment for Pasteurella septica infections typically involves antibiotics. The bacterium is generally sensitive to many common antibiotics, including penicillin, amoxicillin, and tetracycline. However, antibiotic resistance has been reported in some cases, making treatment more challenging.

Prevention[edit | edit source]

Prevention of Pasteurella septica infections primarily involves avoiding animal bites and scratches. This can be achieved by handling animals gently and calmly, and by seeking immediate medical attention if a bite or scratch does occur.
