Characteristics of Factors of Protozoa Blastocystis hominis Persistence.

Persistence activity manifested in the expression of anti-lysozyme, anti-lactoferrin, and antihistone factors promoting inactivation of natural anti-infection resistance factors in the body was revealed in Blastocystis hominis protozoa. Activities of these factors were ranged. The frequency of these factors in clinical isolates of blastocyst decreased in the following order: anti-lactoferrin activity (84.

The Use of Atomic Force Microscopy for Cytomorphological Analysis of Bacterial Infection Agents.

Cytomorphological signs of bacterial infection agents were studied by atomic force microscopy. Analysis of the elastic mechanical characteristics of Staphylococcus spp. from the skin of patients with chronic dermatoses showed lower elasticity of S.

The Use of Cell Elastography to Study the Biomechanical Properties of Bacillus subtilis.

The cytometric, elastic, and adhesion properties of Bacillus subtilis at different terms of culturing were studied. The cytometric parameters of bacterial cells increased by day 6 in culture and decreased at later terms. Analysis of membrane rigidity showed that parameters describing bacterial elastic properties underwent waveform changes: the decrease in bacterial elasticity (from day 1 to 6) was followed by its increase on day 12 in culture.

A comparison of phylogenetic group, virulence factors and antibiotic resistance in Russian and Norwegian isolates of Escherichia coli from urinary tract infection.

Isolates of Escherichia coli from 31 Norwegian and 31 Russian females with significant bacteruria who presented with clinical signs of urinary tract infection (UTI) were tested for antimicrobial sensitivity, the presence of virulence genes, phylogroup distribution and clonal affinity. Twenty isolates, representing the full clonal diversity of a collection of 138 intestinal isolates of E. coli from healthy Norwegian females, served as a reference group.
