In the course of the work done the specific and quantitative composition of the streptococcal autoflora of the fauces of the cosmonauts and the members of backup drew was investigated. In populations of isolated microorganisms the non-pathogenic streptococci have dominated among which S. salivarius prevailed. The same species has constantly been isolated in all the cosmonauts, pre- and postflight. Observation of the microflora state of the fauces at different stages of their professional activity made it possible to reveal the peculiarities of an individual dynamics in the number of nonpathogenic streptococci isolated from tampon depending on the participation of the test-subjects in the previous space missions. This is evidently a reflection of the effect of psychoemotional tension on the state of colonization resistance (CR) of the fauces mucosa and, as result of this, on its microflora. In turn, the occurrence of the individual species of conditionally-pathogenic streptococci after the mission points to a decrease in the CR under effect of unfavourable factors of space mission.

D010614	Pharynx	A funnel-shaped fibromuscular tube that conducts food to the ESOPHAGUS, and air to the LARYNX and LUNGS. It is located posterior to the NASAL CAVITY; ORAL CAVITY; and LARYNX, and extends from the SKULL BASE to the inferior border of the CRICOID CARTILAGE anteriorly and to the inferior border of the C6 vertebra posteriorly. It is divided into the NASOPHARYNX; OROPHARYNX; and HYPOPHARYNX (laryngopharynx).	Throat,Pharynxs,Throats
