Detection of respiratory viruses by PCR assay of nasopharyngeal swabs stored in skim milk-tryptone-glucose-glycerol transport medium.
نویسندگان
چکیده
We analyzed 129 paired nasopharyngeal aspirates (stored in viral transport medium [VTM]) and nasopharyngeal swabs (stored in skim milk-tryptone-glucose-glycerol [STGG] bacterial transport and storage medium) using PCRs to detect adenoviruses, influenza virus A or B, and respiratory syncytial virus (RSV). Overall, swabs stored in STGG medium without antimicrobials were found to be an acceptable alternative to aspirates stored in antimicrobial-containing VTM, with PCR agreement of 90.2% (kappa of 0.8).

Effect of swab composition and use of swabs versus swab-containing skim milk-tryptone-glucose-glycerol (STGG) on culture- or PCR-based detection of Streptococcus pneumoniae in simulated and clinical respiratory specimens in STGG transport medium.
To detect Streptococcus pneumoniae colonization, the nasopharynx is sampled using a swab placed in skim milk-tryptone-glucose-glycerol (STGG) transport medium, and then the swab specimen or STGG medium is cultured or subjected to PCR. We evaluated the effect of swab composition and compared the sensitivities of detection of culture and PCR using swabs and swab-containing medium. Calcium alginat...
متن کاملIn vitro and in vivo comparison of transport media for detecting nasopharyngeal carriage of Streptococcus pneumoniae
BACKGROUND As a standard method for pneumococcal carriage studies, the World Health Organization recommends nasopharyngeal swabs be transported and stored at cool temperatures in a medium containing skim-milk, tryptone, glucose and glycerol (STGG). An enrichment broth used for transport at room temperature in three carriage studies performed in Norway may have a higher sensitivity than STGG. We...
متن کاملSurvival of Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis frozen in skim milk- tryptone-glucose-glycerol medium.
In STGG (skim milk, tryptone, glucose, glycerol) medium at -80 degrees C, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis isolates survived for at least 3 years, and the same species have survived in nasopharyngeal swabs for at least 1.5 years. At -20 degrees C, S. pneumoniae and M. catarrhalis survived for 1.5 years, but H. influenzae survived for only 2 months.
متن کاملValidation of nasopharyngeal sampling and culture techniques for detection of Streptococcus pneumoniae in children in Kenya.
We compared nasopharyngeal swabs against nasal wash cultures for detecting colonizing pneumococci and examined the effect of frozen storage in skim milk-tryptone-glucose-glycerin on culture. Among the 55 children with positive nasal wash cultures, swab cultures were positive for 47 (85%). Of the 96 swabs positive on direct plating, 94 (98%) were positive when recultured after freezing.
متن کاملDetection of avian influenza virus of H9 subtype in the feces of experimentally infected chickens by RT–PCR
Avian Influenza (AI) is a viral respiratory disease of domestic and wild birds. In the diagnostic laboratory, it is essential to have methods for rapid detection of avian respiratory viruses. Cloacal swabs collected from chickens experimentally infected with H9 subtype AI virus, used in a reverse transcription-polymerase chain reaction (RT-PCR) assay for detection of AI. In infected animals, ...
