Pasteurella multocida osteomyelitis caused by cat bite

Pasteurella multocida vertebral osteomyelitis, myositis and epidural abscess in a diabetic cirrhotic patient

Pasteurella multocida is frequently associated with soft tissue infections related to animal bites or scratches. These infections are usually mild but can lead to serious complications especially in high-risk patients. We present a chronic Pasteurella. multocida vertebral osteomyelitis with extensive spondylodiscitis, myositis and epidural abscess in a patient with diabetes and liver cirrhosis. Pasteurella multocida should be suspected in bone and soft tissue infections even if the site of infection is distant to the site of the animal bite, scratch or lick, especially in high-risk patients.

Disseminated Pasteurella multocida infection: Cellulitis, osteomyelitis, and myositis

A 67-year-old man with poorly controlled type II diabetes mellitus was evaluated for right lower extremity erythema and swelling and left-sided lower back pain. He was found to have Pasteurella multocida bacteremia; magnetic resonance imaging showed osteomyelitis of the lumbar spine with myositis in the adjacent left paraspinal muscles. He was initially treated with intravenous antibiotics and was later transitioned to oral amoxicillin. He recovered completely with six weeks of antimicrobial therapy.

Pasteurella canis osteoarticular infections in childhood: review of bone and joint infections due to pasteurella species over 10 years at a tertiary pediatric hospital and in the literature

BACKGROUND

Pasteurella spp. are important bacterial pathogens in both animals and humans. Most reported Pasteurella infections in humans involve skin and soft tissues, often after an animal bite, scratch, or lick to an open wound. Infections involving bone and joints are well recognized, but have not been previously reported due to Pasteurella canis without a history of penetrating dog bite.

METHODS

We report a case of P. canis osteomyelitis in a 14-month-old girl and a case of P. canis septic arthritis in a 19-month-old girl, both occurring without any preceding penetrating injury. Review of all osteoarticular infections due to Pasteurella spp. at our tertiary pediatric hospital over the past 10 years was performed by obtaining the patient records of all children with positive bacterial cultures from any site for Pasteurella spp. as identified through our microbiology laboratory database. A MEDLINE and EMBASE database search was then performed to identify published pediatric cases in the literature since 1950.

RESULTS

In addition to the cases of P. canis osteomyelitis and septic arthritis outlined, we identified 8 children with positive cultures for Pasteurella spp. from the hospital's microbiology database. Two of these children had deep tissue contamination involving bone and/or joints secondary to animal bites. Ten further published cases were identified from the literature since 1950.

CONCLUSIONS

: Established Pasteurella osteomyelitis and septic arthritis secondary to animal bites can be largely prevented through appropriate wound management at the time of injury. However, the potential for deep tissue infection with this organism, including the species P. canis, without prior penetrating injury should be recognized.

LEVEL OF EVIDENCE

Level IV-case series.

Pasteurella abscess in tibial regenerate bone: a case report

Although superficial pin tract infections during limb lengthening are extremely common, most settle spontaneously or with antibiotics. In contrast, deep infection around pin tracts leading to osteomyelitis and abscess formation is much less frequently observed and may need washout and curettage. We report a case of a 10-year-old boy who presented with latent abscess formation at a tibial lengthening site because of Pasteurella, a rare bacterial cause of infection usually associated with animals. To our knowledge, this is the first reported case of abscess formation within regenerate bone associated with this organism and its late presentation in previously well-healed bone is surprising.

[Pasteurella dagmatis spondylodiscitis in a diabetic patient]

INTRODUCTION

Healthy pets contact are able to induce unusual and severe diseases.

CLINICAL CASE

This case reports the medical history of a dorsal spondylodiscitis in a diabetic patient admitted for a chronic wound of his toes. He had a long-standing history of regular consumption of alcohol and tobacco. Blood bottles and biopsy of intervertebral disc infected discovered Pasteurella dagmatis, commonly colonizing the oropharynx of healthy dogs and cats. In this case, licking of his injured toe by his dog was the likely source of entry of the organism.

DISCUSSION

We found no identical cases in the medical literature. Diabetes mellitus and other immunocompromised disorders justify to change behaviours toward domestic animals.

Pasteurella canis osteomyelitis and cutaneous abscess after a domestic dog bite

The genus Pasteurella is part of the normal oral flora of many animals, including domestic cats and dogs. In humans, Pasteurella may cause complications ranging from cellulitis to septicemia but rarely causes osteomyelitis or septic arthritis after bites and/or scratches by cats and dogs. Although Pasteurella multocida is a common cause of infection, other Pasteurella species have also been cultured from wounds in humans. We describe here, a case of a cutaneous abscess and acute osteomyelitis associated with P canis after a domestic dog bite. To our knowledge, no previous case of P canis has been reported as the cause of acute osteomyelitis in humans.

Acute Osteomyelitis of Index Finger Caused by Dog Bite

A forty-seven-year-old man was bitten by a dog on his left index finger. Despite initial antibiotic treatment, he developed acute osteomyelitis of the middle phalanx over the next three weeks. Pasteurella multocida and Bacteroides were isolated from the necrotic bone. Subsequently the infection was successfully treated by debridement and Tetracycline.
