Contamination of microscope slides with Aspergillus glaucus group A: a laboratory problem in the diagnosis of suspected mycotic infections.

Abstract

The microscopic examination of lesions of patients with suspected mycotic infections using slides purchased from foreign countries often showed hyphae. The slides and their wrappings were cultured successfully on Sabouraud dextrose-agar medium. A heavy growth of suspected aspergillus colonies was obtained. These colonies were investigated further by culturing them on both Czapek's solution agar and Malt extract agar. After macroscopic and microscopic examination the fungus was identified as Aspergillus chevalieri from the Aspergillus glaucus group. (7 Clin Pathol 1997;50:699-700) Keywords: Aspergillus glaucus; contamination; microscope slides; mycotic infection Aspergillus species are common airborne contaminants of all surfaces, including skin, mouth, lung, wounds, and so forth. There are about 900 species in the genus Aspergillus. They are among the most common of all environmental fungi. Members of the aspergillus genus are often identified as biodeteriogens. The large number of species comprising the

Laboratory instrument contamination with dermatophytes ? a risk for dermatophytosis

“…Biological contamination of scientific laboratory equipment, such as microscope, incubator, refrigerator, freezer, gas flame, centrifuge, rotator, balance and so on, may pose a potential health risk to personnel who work, service, repair and handle the equipment (Sewell 1995; Ghadjari et al. 1997; Neely and Orloff 2001).…”

This laboratory equipment is commonly used by several students every week, and the specific results indicated that the equipment was contaminated with fungi, and students and staff were potentially exposed while working to these instruments, and therefore these fungi, which cause transmittable diseases.…”
