An interesting case of failed renal transplant complicated by a lymphocele infected with Pasteurella multocida and a review of the literature

Microbiological analysis of infectious lymphocele: Case series and literature review

BACKGROUND

Infectious lymphocele is a rare post-operative complication of abdominal surgery, and few studies have focused on its causative organisms. The aim in this research is to clarify microbiology and appropriate empiric treatment of infective lymphocele.

METHODS

We performed a single center, retrospective observational study between April 2000 and March 2018 with a case review and literature search. Data were collected in a chart review.

RESULTS

Twenty-four cases were founded in our institution. 153 cases, including 16 cases from our institution, that detected causative organisms was also analyzed. Infectious lymphocele was found to occur post gynecological/urological surgery in cancer patients. We also reported that bacteremia incidence and the mortality rate of infectious lymphocele cases were very low. The major sites of infectious lymphocele were pelvis or inguinal area. Our case series and literature review showed Gram positive cocci were the major causative organisms, with Staphylococcus aureus constituting one third of them (53/153 cases). Streptococcus species (26/153cases) and coagulase negative Staphylococci (17/153 cases) were the second and third most detected organisms.

CONCLUSION

In gynecologic and urologic cancer patients, Gram positive cocci were the most common organisms causing lymphocele infection. Gram-positive coverage might be reasonable for empiric therapy in infectious lymphocele.

A Rare Case of Glossitis due to Pasteurella multocida after a Cat Scratch

Pasteurella is one of the zoonotic pathogens that can cause variety of serious infections in animals and humans such as bacteremia, septic shock, endocarditis, meningitis, prosthetic and native valve infections, osteomyelitis, skin and soft tissue infections, abscesses, and even pneumonia with empyema. However, there have been few reports of upper respiratory involvements like tonsillitis and epiglottitis in humans. We present a case of recurrent Pasteurella glossitis after a cat scratch which has not been reported in humans.

Pasteurella multocida: from zoonosis to cellular microbiology

In a world where most emerging and reemerging infectious diseases are zoonotic in nature and our contacts with both domestic and wild animals abound, there is growing awareness of the potential for human acquisition of animal diseases. Like other Pasteurellaceae, Pasteurella species are highly prevalent among animal populations, where they are often found as part of the normal microbiota of the oral, nasopharyngeal, and upper respiratory tracts. Many Pasteurella species are opportunistic pathogens that can cause endemic disease and are associated increasingly with epizootic outbreaks. Zoonotic transmission to humans usually occurs through animal bites or contact with nasal secretions, with P. multocida being the most prevalent isolate observed in human infections. Here we review recent comparative genomics and molecular pathogenesis studies that have advanced our understanding of the multiple virulence mechanisms employed by Pasteurella species to establish acute and chronic infections. We also summarize efforts being explored to enhance our ability to rapidly and accurately identify and distinguish among clinical isolates and to control pasteurellosis by improved development of new vaccines and treatment regimens.

Invasive Pasteurella multocida sinusitis in a renal transplant patient

Pasteurella are commensal gram-negative bacteria isolated from the oral cavity of many domesticated animals. Most human infections occur post animal bite or scratch injury resulting in local cutaneous infection; however, case reports suggest that transmission may occur via animal secretions. Pasteurella species can be associated with serious systemic infections particularly in those with underlying disease and in the immunocompromised. We present a case of invasive Pasteurella multocida sinusitis in an immunocompromised renal transplant patient most likely acquired from a pet dog through direct mucosal inoculation via licking.

Pasteurella multocida urinary tract infection in a pediatric patient with end-stage renal disease

Pasteurella multocida is a Gram-negative bacillus that is part of the normal oral flora of cats and dogs. Most infections involving P. multocida are soft tissue infections after animal bites or scratches. We present a case of P. multocida urinary tract infection in a 13-year-old boy with end-stage renal disease receiving peritoneal dialysis. He was successfully treated with intravenous ampicillin-sulbactam followed by oral amoxicillin-clavulanate. Thirteen additional cases of P. multocida urinary tract infection (12 adults and one pediatric patient) reported in the literature were reviewed. Underlying medical illnesses and structural urologic abnormalities are risk factors.

Infections in recipients of kidney transplants

A review of infections in kidney transplant recipients is presented in this article, beginning with a discussion of the pretransplant infectious diseases evaluation and an overview of the timing of infectious posttransplant, and then focusing on individual types of infection.
