Severe fungal infestation by Aspergillus terreus was documented in the otic region but not in any other site of the body. Adjacent to the promontorium, massive accumulation of fibrinous secretion and infiltration of clusters of inflammatory cells were present. Newly formed cysts and vessels replaced the round window membrane location, reminiscent of granulation tissue. Inflammatory cells and a severe fibrin net were noted within the perilymphatic spaces of scala tympani and scala vestibuli, indicative of an

acute fibrinous otitis. Inflammatory reactions have probably been caused by this fungal organism. The basilar membrane was solely covered by a simple cuboidal epithelium. Complete learn more absence of sensory cells of the Organ of Corti characterised a further severe phenomenon, which possibly led to the animal’s poor nutritional status and stranding. Potential portals of entry are being discussed. “
“Fungaemia diagnosis could be improved by reducing the time to identification of yeast from blood cultures. This study aimed to evaluate three rapid methods for the identification of yeast direct from blood cultures; Gram’s stain analysis, the selleck chemical AdvanDX Peptide Nucleic Acid in Situ Hybridisation Yeast Traffic Light system (PNA-FISH YTL) and Bruker Sepsityper alongside matrix-assisted laser desorption ionisation time of flight mass spectrometry (MALDI-TOF MS). Fifty blood cultures spiked with a known single yeast

Dichloromethane dehalogenase strain were analysed by blinded operators experienced in each method. Identifications were compared with MALDI-TOF MS CHROMagar Candida culture and ITS rRNA sequence-based identifications. On first attempt, success rates of 96% (48/50) and 76% (36/50) were achieved using PNA-FISH YTL and Gram’s stain respectively. MALDI-TOF MS demonstrated a success rate of 56% (28/50) when applying manufacturer’s species log score thresholds and 76% (38/50) using in-house

parameters, including lowering the species log score threshold to >1.5. In conclusion, PNA-FISH YTL demonstrated a high success rate successfully identifying yeast commonly encountered in fungaemia. Sepsityper™ with MALDI-TOF MS was accurate but increased sensitivity is required. Due to the misidentification of commonly encountered yeast Gram’s stain analysis demonstrated limited utility in this setting. “
“Severe Candida infections are increasing and are associated with considerable morbidity and mortality. Rapid and accurate differentiation of Candida albicans from non-C. albicans species is essential for therapeutic decisions. We therefore developed a fluorescence in situ hybridisation (FISH) assay comprising previously described probes and a newly designed specific C. albicans probe/competitor probe combination. The FISH probes were first evaluated using 99 selected fungal strains covering 31 species, and a specificity between 96% and 100% and a sensitivity of 100%.
