[Algorithm for the coproscopic diagnosis of human intestinal parasites].

The purpose of the study was to elaborate a detection algorithm for human intestinal helminth eggs. There is a broad spectrum ofcoproscopic methods recommended for the detection of Opisthorchis eggs in man and animals; these include Fulleborn's method, formalin-ether method, Goryachev's, Katoh's, Kalantaryan's, Shcherbovich's, and Kotelnikov-Varenichev methods. Combined coproscopic methods are significantly more effective in detecting the causative agents of enteric parasitoses than is Katoh's method. Among the considered coproscopic techniques for the diagnosis of human ascariasis, it is most rational to use a combined method for fecal examination, the basis for which is a multicomponent flotation system (such as the author's one). The Kotelnikov-Varenichev method is optimal for diagnosing opisthorchiasis. It is optimal to use 2-3 methods of different groups simultaneously for the screening diagnosis of intestinal parasitoses.

[Role of pathogenicity factors of Staphylococcus aureus in development of atopic dermatitis].

Factors of pathogenicity of staphylocci and their key role in pathologic process are discussed. Staphylococcus aureus is the leading etiological agent infecting skin of the patients with atopic dermatitis. Development of atopic eczema in patients infected by Staphylococcus aureus is in much determined by wide spectrum of virulence factors inherent to this type of staphylococci. Among those, the more important are proteinases, destroying antimicrobial peptides of derma, toxins, superantigens, which can cause and support of inflammatory reaction in derma during this disease. It was specially noted that pathogenicity factors should be studied as complex system, which formed as a result of long joint evolution of opportunistic microflora and immune system of the host.
