СЕРОГРУППОВАЯ ПРИНАДЛЕЖНОСТЬ β–ГЕМОЛИТИЧЕСКИХ СТРЕПТОКОККОВ, ИЗОЛИРОВАННЫХ ОТ РАЗНЫХ ВИДОВ ЖИВОТНЫХ И ПТИЦ В СЕЛЬСКОХОЗЯЙСТВЕННЫХ БИОТОПАХ КАБАРДИНО-БАЛКАРСКОЙ РЕСПУБЛИКИ

Abstract

The serogroup affiliation of β-hemolytic streptococci isolated from clinically healthy farm animals of various species, from pathological material from sick, dead and forcedly slaughtered animals, as well as those isolated in premises where farm animals are kept in farms of various forms of ownership of the Kabardino-Balkarian Republic was studied. The hemolytic properties of streptococci were studied on blood (5% sheep erythrocytes) agar. The determination of the serogroup affiliation of streptococci was carried out by us in accordance with generally accepted methods, in accordance with which 639 cultures were tested that showed β-hemolysis on blood agar, including: from cattle - 207 (32.3%), from small cattle - 167 (26.1%), from horses - 65 (10.1%), from pigs - 39 (8.3%), from dogs - 73 (11.1%), synanthropic rodents - 40 (6.1%) %), synanthropic birds - 24 (3.7%), as well as 24 (3.7%) cultures isolated from air samples and washings from walls and floors in livestock buildings. Of 639 cultures of β-hemolytic streptococci, serogroup affiliation was determined in 549 (86.9%). At the same time, 30 (5.5%) were assigned to group A, 131 (23.8%) to group B, 158 (28.7%) to group C, 81 (14.7%) to group G , to group F - 24 (4.3%), to group E - 23 (4.1%), to group P - 15 (2.7%), to group U - 16 (2.9%) and 71 (13.1%) cultures could not be identified as belonging to one or another serological group. Streptococci with β-hemolytic properties are widely distributed among cattle, horses, small cattle, dogs and pigs living in agricultural biotopes.
