Примери за streptococci

• An experiment was conducted in which streptococci extracted from throats of patients with pharyngitis were grown at room temperature on a medium containing eggs.

• It often follows an upper respiratory tract infection, particularly with streptococci.

• Investigations suggest that substantial amounts of streptococci are disseminated when nasal carriers sneeze or cough.

• The pre-treated streptococci were allowed to attach to human enamel or glass (favoured for its transparency).

• They showed at most a concentration of 40 thermotolerant coliforms and six faecal streptococci per 100 ml of water.

• The first samples were examined for total coliforms, thermostable coliforms and faecal streptococci.

• There was also no significant difference between the numbers of total streptococci between all groups.

• Further study of the growth and survival of streptococci in food is needed in order to prepare recommendations for prevention of food-borne streptococcal pharyngitis.

• Small particles of saliva and aerosol contaminated by streptococci, which are inhaled into the respiratory tract, expose the nasal and bronchial mucosa more easily to the pathogen.

• Streptococci involved in food-borne infections were found to be sensitive to penicillin.

• M protein is a major factor in determining the virulence of streptococci.

• Cultures from the abscesses grew alpha-hemolitic streptococci.

• There was also no significant difference between the numbers of total streptococci between groups demineralized for 2, 5 and 6 days or between those demineralized for 5 and 8 days.

• Streptococci were only cultured from one (conventional) brush.

• Staphylococci and streptococci are the commonest organisms.
