Q fever outbreak among travelers to Germany associated with live cell therapy - United States and Canada, 2014: a co-publication.

WHAT IS ALREADY KNOWN ON THIS TOPIC?: Q fever is a zoonotic disease caused by Coxiella burnetii and is usually transmitted through inhalation of air contaminated with animal excreta. The disease is considered to be underdiagnosed because symptoms are nonspecific and can vary from patient to patient, making diagnosis difficult. WHAT IS ADDED BY THIS REPORT?: During September-October 2014, the New York State Department of Health identified Q fever in five patients with exposure to a treatment known as live cell therapy, an alternative medicine practice involving injections of fetal sheep cells, which is a type of xenotransplantation. Investigation revealed that a group of U.S. residents traveled to Germany twice a year to receive this treatment. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: Clinicians should consider zoonotic diseases, such as Q fever, in patients whose history includes receipt of a treatment known as live cell therapy. International travel for xenotransplantation procedures can facilitate transmission of zoonotic disease.

Disseminated Mycobacterium immunogenum infection presenting with septic shock and skin lesions in a renal transplant recipient.

Mycobacterium immunogenum is a relatively new species within the Mycobacterium chelonae-Mycobacterium abscessus group of rapidly growing mycobacteria (RGM). M. immunogenum was first characterized in 2001 and, similar to other RGM, is an ubiquitous environmental organism. This organism has most commonly been implicated in cutaneous infection in both healthy and immunosuppressed patients. To our knowledge, this is the first reported case of septic shock in the setting of disseminated M. immunogenum infection. Definitive identification of this organism requires gene sequencing at specialized centers, which may limit its detection. M. immunogenum is resistant to many anti-mycobacterial agents, and treatment can be especially challenging in transplant patients, given potential drug interactions and added toxicities. It is important to distinguish M. immunogenum from other RGM and determine the susceptibility profile to devise a successful treatment plan, particularly in the transplant population in which it can potentially cause severe, disseminated disease.
