[Genetic characterization of clinical Klebsiella isolates circulating in Novosibirsk].

72 clinical strains of Klebsiella spp. isolated from samples obtained from humans in Novosibirsk, Russia, were analyzed. Species identification of strains was performed using 16S rRNA and rpoB gene sequences.

Antibiotic Resistance and Pathogenomics of Circulating in Novosibirsk, Russia.

A total of 394 strains of staphylococci found in humans and pets in Novosibirsk, Siberian Russia, were characterized in terms of antibiotic resistance and corresponding genes. Two coagulase-positive and 17 coagulase-negative species were identified. The majority of isolates, with the exception of and hospital isolates, were sensitive to most of the tested antibiotics, and isolates from pets displayed the lowest level of resistance.

Resident alveolar macrophages are master regulators of arrested alveolarization in experimental bronchopulmonary dysplasia.

Trophic functions for macrophages are emerging as key mediators of developmental processes, including bone, vessel, and mammary gland development. Yolk sac-derived macrophages mature in the distal lung shortly after birth. Myeloid-lineage macrophages are recruited to the lung and are activated under pathological conditions.
