Ralstonia mannitolilytica is a glucose non-fermentative, aerobic gram-negative bacillus formerly known as Ralstonia picketti biovar3/ "thomasii" of relatively low virulence. It has been isolated from a wide kind of infections like bacteremia, meningitis, endocarditis, osteomielitis and from the respiratory tract of patients with cystic fibrosis. The case presented is related to a 26-year-old male patient with diabetes insipidus, hypothyroidism and histiocytosis X with a two-day-febrile syndrome and chills associated with the presence of a porthacat catheter used for administrating medication. An episode of catheter-related bloodstream infection was documented by using Bact-Alert blood culture system and differential-time-to-positivity method for central venous catheter versus peripheral blood cultures (>120min). Once removed, it was confirmed through Maki semiquantitative technique (>15 ufc). The microorganism was identified by API 20 NE, Vitek 2C and Vitek 1 as. Ralstonia mannitolilytica.

Allergic fungal rhinosinusitis is a benign and non-invasive sinusal disease related to a hypersensitivity reaction to fungal antigens. This process can cause tissue edema with chronic inflammatory disturbances of the respiratory mucosa. We present the case of a 17 year-old immunocompetent male, with history of seasonal allergic rhinosinusitis, nasal polyps and previous surgery for mucocele of the frontal sinus. Sticky material was removed in the last surgery that revealed pigmented and septed filaments on direct examination, and yielded Curvularia on Sabouraud dextrose agar. After a course of amphotericin B, treatment was switched to itraconazole, with good tolerance and favorable clinical outcome. © 2011.

Ochrobactrum anthropi is a non-glucose fermentative, aerobic gram-negative bacillus, formerly known as Achromobacter sp or CDC group Vd. It has been isolated from the environment and from infections in usually immunocompromised human beings. The documented infections frequently involved catheter related bacteremia whereas endophthalmitis, urinary infections, meningitis, endocarditis, hepatic abscess, osteochondritis, pelvic abscess and pancreatic abscess were rarely involved. Here it is presented the case of a male patient aged 69 years with sustained hypotension, four day febrile syndrome, chill, lavish perspiration and sensorium deterioration. He had type 2 diabetes and antecedent of cerebrovascular accident. A double-lumen dialysis catheter was present due to chronic renal insufficiency. An episode of catheter-related bloodstream infection was documented by using Bact-Alert Blood Culture System and Differential-Time-to-Positivity Method for central venous catheter versus peripheral blood cultures (>120 min). Once removed, it was confirmed through Maki semi quantitative technique (>15 FCU). The microorganism was identified by API 20NE and Vitek 1 as Ochrobactrum anthropi.
