Brevundimonas bacteremia: Two case reports and literature review

Brevundimonas spp. are infrequently isolated from clinical samples, including blood. The vast majority of reported cases have underlying diseases. Whether these microorganisms represent true pathogens of human disease in all populations remains to be explored. We present 2 cases of bloodstream infection caused by Brevundimonas sp., with one of these individuals immunocompetent, and discuss the possible role of these organisms in different patient populations.

Pseudomonas mendocina spondylodiscitis : A case report and literature review

Pseudomonas mendocina is rarely recovered as a human pathogen. Only 2 human cases have been reported in the literature. Here, we report the third human case and possibly the first 1 to involve spinal infection caused by such an unusual bacterium.

Acute acalculous cholecystitis: A rare presentation of typhoid fever in adults

Adult typhoidal acute acalculous cholecystitis is rare with only 2 cases having been reported in the English literature. We present the case of a previously healthy 36-y-old female who suffered fever, chills, epigastralgia and progressive jaundice for 3 d, with acute acalculous cholecystitis subsequently diagnosed. In addition to antibiotic therapy with ceftriaxone, open cholecystectomy was performed. However, bile and blood culture both showed Salmonella typhi growth unexpectedly, and ileocolitis was revealed by colonoscopy. Careful tracing of the history of the patient recalled a history of travel to Indonesia. In adults without common risk factors for acalculous cholecystitis, a detailed history including travel to endemic areas and high index of suspicion for typhoidal acute acalculous cholecystitis are important, and appropriate antimicrobial therapy for covering Salmonella typhi should be considered.
