Table 2 Bacterial MP loads and duration of MP infection

From: High Mycoplasma pneumoniae loads and persistent long-term Mycoplasma pneumoniae DNA in lower airway associated with severity of pediatric Mycoplasma pneumoniae pneumonia

 Group LT (n = 50)Group NLT (n = 44)
Positive MP loads in throat swab (n/disease course/ copies/ml)15/(22–45)days/103–53/(18–22)days/102–3
Negative MP loads in throat swab (n/disease course)5/(26–31)days7/(19–22)days
Highest MP loads in BALF
 High load (n/%/copies/ml)44/(88%)/ 107–82/(4.54%)/107–8
