Title : Repercussions of pasteurella multocida infection in humans: A case report
Abstract:
Pasteurella multocida is a gram-negative bacterium commonly found in the respiratory and gastrointestinal tracts of animals, such as cats, dogs and birds. This bacterium is known to cause a variety of infections in animals and can occasionally be transmitted to humans, resulting in infections known as pasteurellosis. In humans, it generally occurs after direct contact with infected animals, such as bites, scratches or licks. Some of the manifestations caused by this bacteria include skin, respiratory and/or systemic infections. Patient, 14 years old, male, mixed race, student, presented to the emergency room, accompanied by his mother, presenting with tachycardia, tachypnea, hypotension, polyarthralgia with edema on the right upper limb and lower limbs that started a week ago, after dog bite to the second finger on the right and fall followed by injury to the right knee. On physical examination, retroauricular and cervical lymph node enlargement, jaundice (Kramer zone 3), calf enlargement, board-like abdomen and significant hepatomegaly. The patient was taken to the Intensive Care Unit, where imaging tests such as Joint and Abdomen Computed Tomography were requested. Furthermore, his laboratory tests showed significant leukocytosis and a slight change in bilirubin. His serologies for HIV, syphilis and hepatitis B and C were nonreactive. Joint puncture was performed and purulent secretion was drained. Vigorous hydration and empirical broad-spectrum antibiotic therapy (ceftriaxone with metronidazole) were initiated until the test results were obtained. The patient improved after three days of treatment. There was a case of sepsis, with a focus on the skin, which was unusual, which presented a favorable outcome at first, however, after 6 months, the patient returned to the office for follow-up, with a characteristic picture of osteomyelitis, on imaging examination, which was possibly disseminated hematogenously.
