[The role of neutrophil CD64 index in the diagnosis of infectious complications after colorectal resection].

Objective: To determine diagnostic value of neutrophil CD64 index (iCD64n) in the diagnosis of postoperative infectious complications after colorectal resections.

Material And Methods: Seventy-three patients underwent colorectal surgery for the period from January to December 2018. These patients were included into a single-center study.

[Lecithinase activity of Vibrio cholerae and of vibrios not agglutinated by O-cholera serum].

The lecithinase activities of 187 V. cholerae strains differing in their virulence and 70 cultures of NAG vibrios of different origin varied in all experimental groups. The level of lecithinase activity in the groups of V.

[Phage typing of nonagglutinating vibrios isolated in the territory of the USSR].

The work presents the results of the phage typing of 2,437 NAG vibrio strains isolated in the USSR from patients and carriers (374 strains), from open water basins (1,675 strains), from sewage (234 strains) and from bottom silt (172 strains). Phage typing was carried out with a set of 5 phages capable of lyzing enteropathogenic NAG vibrios (phages TEPV 1, 2, 3, 4, 5). NAG vibrios isolated from humans were sensitive to phages TEPV in 45% of cases and NAG vibrios isolated from the environment, only in 29.
