    (Open Access Macedonian Journal of Medical Sciences, 2023-01-17) Ananieva, M.; Faustova, M.; Loban, G.; Avetikov, D.; Tkachenko, P.; Bobyr, V.; Dobrovolska, O.; Ананьєва, Майя Миколаївна; Фаустова, Марія Олексіївна; Лобань, Галина Андріївна; Аветіков, Давид Соломонович; Ткаченко, Павло Іванович; Бобир, В.

    Background: The limited amount of information available today does not fully reflect the biological properties of Streptococcus pluranimalium as a pathogen new to humans, its pathogenicity factors, and, as a consequence, the pathogenesis of diseases, which is causes Aim: The aim of this research was to study the biological properties of S. pluranimalium, its sensitivity to antibiotics and antiseptics, as well as its adhesive properties. Methods: Two hundred samples were collected from the coronal pockets in patients with acute purulent pericoronitis during 2019–2021 years. Among them, five clinical strains of S. pluranimalium were isolated. Final identification was carried out using a Vitec-2compact bioMérieux automatic bacteriological analyzer. The sensitivity of the studied microbial strains to antibiotics of various groups was determined by the disk diffusion method. The adhesive properties of S. pluranimalium were determined according to the standard Brilis method. Results: It possesses typical morphological and cultural properties characteristics of the genus Streptococcus representatives. This microorganism virtually does not break down carbohydrates, but it produces arylamidases that enables it to be differentiated from other streptococci. S. pluranimalium demonstrates variable sensitivity to antibiotics; the lowest sensitivity has been found out to the second-generation fluoroquinolones. In addition, the clinical isolates studied show high adhesive properties to human red blood cells.

    Streptococcus pluranimalium as a new causative agent of acute pericoronitis: a rare case report
    (2019) Faustova, M. O.; Ananieva, М. M.; Loban’, G. A.; Dobrovolska, O.; Basarab, Ya. O.; Petrenko, R. V.; Фаустова, Марія Олексіївна; Ананьєва, Майя Миколаївна; Лобань, Галина Андріївна; Басараб, Ярослав Олексійович; Петренко, Руслан Володимирович
    Difficult tooth eruption or pericoronitis is a very common disorder, which seems to be the most frequent reason of extraction of third molars. It is accompanied by an inflammation of the soft tissues. According to the literature, the microflora of pericoronal pouch mainly consists of hemolytic Streptococcus and anaerobic species of Prevotella and Veillonella genera. However, changes in population immunity and development of diagnostic methods led to some changes of microbiota composition. Moreover, there are no case reports which show presence of Streptococcus pluranimalium in the human oral cavity and its ability to cause a pathology of the maxillo-facial region. This report describes the first case of identification S. pluranimalium as a pathogen among microorganisms of the oral cavity and proves its main role in development of acute purulent pericoronitis.
