Shock séptico de foco respiratorio por Pasteurella multocida en un paciente inmunocompetente. Caso Clínico / Septic shock originating from a pulmonary focus caused by Pasteurella multocida. Report of one case

Pasteurella multocida is a gram-negative coccobacillus bacterium found as a commensal in the oropharynx of domestic animals such as cats and dogs and some farm animals. Soft tissue infections and occasionally bacteremia in immunocompromised patients with direct contact with animals are described. We report a 61 year old male with a history of scratches and close contact with domestic cats, with a septic shock originating from a pulmonary focus, requiring mechanical ventilation and vasopressors. Blood cultures disclosed the presence of Pasteurella multocida. He responded successfully to antimicrobials.

Pasteurella multocida Infection of the Calf in a Patient Who had Moxa Cautery Treatment for Degenerative Arthritis

Pasteurella multocida infection in man is rare. This organism was isolated from a calf infection of a 48-year-old woman with degenerative arthritis who had the history of treatments with prednisolone, acupuncture and moxa cauterization. She did not have any animal contact. It was condsidered probable that the organism invaded through the cauterization ulcers. The organism was difficult to identify, because of its superficial resemblance to other organisms. Oxi/Ferm and N/F systems failed to identify the isolate. The organism was susceptible to many antimicrobial agents tested except to amikacin and clindamycin.
