Identification of Hafnia alvei with the MicroScan WalkAway system.

Hafnia alvei is a gram-negative facultatively anaerobic bacillus that belongs to the family Enterobacteriaceae. This organism is a causative agent of intestinal disorders and is found in different environments. H. alvei has received increased clinical attention as a cause of different infections in humans. This study was performed to compare the MicroScan WalkAway automated identification system in conjunction with the new MicroScan Combo Negative type 1S panels with conventional biochemical methods for identification of 21 H. alvei strains. The MicroScan WalkAway system was found capable of correctly identifying 20 of the 21 strains tested.

Use of bile cytology for early diagnosis of complications in orthotopic liver transplantation.

We conducted a daily analysis of bile cellularity in 25 patients undergoing 29 orthotopic liver transplants (OLT) and correlated the cytological parameters with the clinical outcome of each patient. The 16 patients without complications only showed slides with cells during the first 4-5 postoperative days. The four patients with primary non-function (PNF) of the graft had a high cell density up to the time of the retransplant, with a preponderance of polymorphonuclear (PMN) leucocytes (59.2%) and epithelial cells (29.2%). During the episodes of sepsis (n = 3) and rejection (n = 7) we noted the sudden appearance of high cellularity, almost exclusively PMN leucocytes (96.5%), and a preponderance of PMN leucocytes (84.2%) with appreciable percentages of mononuclear cells and macrophages as well as the early appearance of lymphoblasts in the rejection episodes. Our results show that bile cytology can be a useful method for diagnosing graft complications in liver transplantation.
