We describe a case of bacteraemia caused by Weissella confusa in a 48-year-old male who was operated on for adenocarcinoma of the gastro-oesophageal junction and maintained on total parenteral nutrition. Blood cultures were positive for a vancomycin-resistant streptococcus-like organism which was identified as W. confusa by 16S rRNA gene sequencing.
BACKGROUND Infections caused by Nocardia farcinica are potentially lethal because of the organism's tendency to disseminate and resist antibiotics. Central nervous system involvement has been documented in 30% of infections caused N. farcinica. METHODS Case report and review of the literature. RESULTS A case of primary brain abscess caused by N.(More)
The present study highlights six cases of pneumococcusuria during the time period of May 2008 to May 2010. All the patients had a co-existing predisposing factor with the isolation of Streptococcus pneumoniae in urine. Five of the six patients having signs and symptoms of urinary tract infections (UTI) were treated and cured of the same. It becomes(More)
Reports of oxacillin-susceptible mecA-positive Staphylococcus aureus strains are on the rise. Because of their susceptibility to oxacillin and cefoxitin, it is very difficult to detect them by using routine phenotypic methods. We describe two such isolates that were detected by chromogenic medium and confirmed by characterization of the mecA gene element.
A 49-year-old male with underlying liver disease presented with fever and signs of sepsis. Non-O1/non-O139 Vibrio cholerae was isolated from his blood culture, which was positive for the hlyA and toxR genes. We report this fatal case of non-O1/non-O139 V. cholera sepsis and review the literature on non-O1/non-O139 V. cholerae sepsis in patients with chronic(More)
Coryneform bacteria belonging to the genus Brevibacterium have emerged as opportunistic pathogens. Of the nine known species of Brevibacterium isolated from human clinical samples, Brevibacterium casei is the most frequently reported species from clinical specimens. We report the first case of B. casei brain abscess in an immunocompetent patient(More)
Central nervous system trichosporonosis is a rare clinical entity and so far only six cases including three each of brain abscess and meningitis has been on record. We report a rare case of chronic meningo-ventriculitis and intraventricular fungal ball due to Trichosporon asahii in an 18-year-old immunocompetent male from Burundi, east Africa.(More)
OBJECTIVES To determine the minimum inhibitory concentration of ciprofloxacin among 50 blood stream isolates of Salmonella enterica. MATERIAL AND METHODS A total of 50 consecutive isolates of Salmonella enterica were tested for susceptibility to antimicrobials using the Kirby Bauer disk diffusion method. Minimum inhibitory concentrations were determined(More)
