        Kodamaea ohmeri, previously known as Pichia ohmeri or Yamadazyma ohmeri, is an ascosporogenous yeast that belong to the Saccharomycetaceae family, and it is a rare yeast-form fungus recently identified as an etiological agent of fungemia, endocarditis, urinary tract infection and peritonitis in immunocompromised patients. This paper presents a case of K. ohmeri fungemia in a 70-year-old man with carcinoma of the ampulla of Vater. After receiving endoscopic retrograde cholangiopancreatography (ERCP) for releasing obstruction of ampulla of Vater by insertion of the biliary stent, he was pyrexial with a temperature of 38.5°C. Two set of blood samples were obtained from a peripheral vein for culture. The pathogen was identified as K. ohmeri using the Vitek YST card (bioMérieux, France) and was confirmed by the sequencing of the D1/D2 domains of the 26S rRNA gene and the internally transcribed spacer region. The minimal inhibitory concentrations of the antifungal agents were as follows: amphotericin B 0.5 μg/mL; fluconazole 2 μg/mL; voriconazole ≤ 0.12 μg/mL; fluocytosine ≤ 1 μg/mL. According to the Clinical and Laboratory Standard Institute recommended breakpoint for Candida spp, the isolate was susceptible to fluconazole, amphotericin B, voriconazole, and flucytosine. This is the first report of the isolation of K. ohmeri in the patient with a gastrointestinal neoplasm following ERCP.

        Antibiotic resistant salmonellosis has shown a recent increase, making treatment of patients with Salmonella infections difficult. This study analyzed changes in the species, serogroups, and antimicrobial susceptibility of enteric pathogens isolated from stool specimens during a period of eight years from 2003 to 2010 in a tertiary hospital. In total, 237 pathogens (1.9%) were isolated from 12,289 stool specimens, comprising 50.6% NTS and 49% Vibrio parahaemolyticus. Serogroups D, B, and C Salmonella were isolated most frequently, in that order. Of the Salmonella, 49% of the isolates were ampicillin resistant and this rate for serogroups B, C, and D Salmonella was 56.8, 64.7, and 43.5%, respectively. Overall, the rates of trimethoprim-sulfamethoxazole (SXT), chloramphenicol (CM), and ciprofloxacin resistance were 11.0, 22.0, and 0%, respectively. Two cefotaxime-resistant Salmonella were isolated in 2010. All of the V. parahaemolyticus were susceptible to SXT, CM, and tetracycline. In conclusion, NTS and V. parahaemolyticus were the major enteric pathogens isolated from stool during the eight years examined, and the rate of Salmonella resistance to antimicrobial agents showed a significant increase. Antimicrobial susceptibility testing is mandatory for proper treatment of patients with Salmonella spp. infection.
