Direct microscopic examination

Demodicidosis is a chronic skin disease, caused by two species of Demodex (D. folliculorum and D. brevis). Demodex infected individuals are mainly symptomless and may have pathogenic symptom only when mite density is high within the skin. Objectives: To compare the value of the Standardized skin surface biopsy (SSSB) and direct microscopic examination with KOH (DME) for assessing Demodex density.

To determine the prevalence of intestinal parasites among school children belonged to different communities from urban, peri-urban and rural areas in Khurda district, Odisha, India. Stool samples were collected from the school children according to the standard procedures. All the stool samples were examined by the direct microscopic examination and by the formalin - ether concentration methods. A total of 1114 stool specimen were collected from different schools in 1995.

The present article reports on the laboratory examination of skin scraping sample collected from a camel clinically infected with dermatophyte infection. The samples were examined by direct microscopical examination by placing the skin scrapings and/or hairs in 20% KOH on a glass slide and gentle heating, without boiling. The dermatophyte identification was made based on the colony characteristics and microscopic features of the fungal isolates according to the methods. The present study revealed the presence of superficial dermatophyte skin infection in the affected camel.

Onychomycosis is a fungal infection of the finger or toe nail caused by various fungal agents like dermatophytes, non dermatophytes moulds and yeasts. It is necessary to diagnose the infection with proper laboratory evidences before treating them with antifungal drugs, which require prolonged duration of treatment and may have adverse side effects. This study involves comparison of standard laboratory tests in the diagnosis of onychomycosis, namely, potassium hydroxide mount (KOH mount), Calcofluor white staining and fungal culture of the nail clippings.

Otomycosis is an acute, subacute or chronic fungal infection of the external auditory canal. It is worldwide in distribution with a higher prevalence in the hot, humid, and dusty areas of the tropics and subtropics. A wide variety of fungi can cause Otomycosis. In this study, our aim was to determine the most common mode of presentation, predisposing factors, and the spectrum of fungi involved in Otomycosis. 60 Ear discharge samples were collected aseptically using two sterile cotton swabs. One swab was used for direct microscopic examination and used for fungal culture.

In Senegal, an efficient and effective struggle against intestinal parasites and there, their affections (bordering 40 % of the global nature of the tropical diseases other than the malaria especially in the African regions), requires essentially a good knowledge on one hand of their frequencies and geographical distributions, and on the other hand of their assessments and epidemiological distributions, and on the other hand of their assessments and epidemiological evolutions.
