Two studies performed in the 1990s proposed Gram stain rejection criteria for tracheal aspirate specimens with >10 squamous epithelial cells or no organisms detected on the Gram stain for, Tracheal Aspirate Cultures: The Challenges. Complications including rheumatic fever, sepsis, severe soft tissue invasion, and toxic shock-like syndrome (TSLS) are reported to be most common with the M1 serotype and a unique invasive clone has become the predominant cause of severe streptococcal infections.3. comprise 25% of the organisms present. Streptococcus pyogenes: (group A -hemolytic strep) and other -hemolytic streptococci in groups B, C, D, and G are generally susceptible to penicillin and its derivatives, therefore, susceptibility need not be routinely determined. 13 S. pneumoniae 1 and H. influenzae 14 are present in the nasopharynx . Place swab in transport. Experts dont know the precise incubation period of Haemophilus influenzae. As mentioned above, Gram stain rejection guidelines exist for sputum samples, but not for tracheal aspirate specimens.

It is important to understand how some of the most common causes of pneumonia transition from colonizers to opportunistic pathogens. Additionally, fastidious (but important) organisms may be overgrown by non-fastidious organisms within the specimen before it is ever cultured in the laboratory, resulting in misleading culture results. Test Includes: Culture for routine aerobic flora and Streptococcus pyogenes (groups A, C, G streptococci). A throat swab culture, or throat culture, is a test commonly used to diagnose bacterial infections in the throat. [Full Text]. heavy growth of normal upper respiratory flora.
