- The study aimed to identify and analyze the genetic characteristics of human bocavirus (HBoV) in children suffering from acute respiratory infections in Tianjin, China, using 1,259 nasopharyngeal samples collected in 2012.
- Results showed that 4.53% of the samples tested positive for HBoV, predominantly in children aged 6-36 months, with a peak of infections occurring in summer and instances of co-infections with other respiratory viruses.
- Phylogenetic analysis revealed a high genetic similarity between the detected HBoV strains and known strains, indicating minimal gene sequence variations among them.
A study was conducted to analyze the types and drug resistance of Streptococcus pneumoniae in Chinese children under 5 with pneumonia, involving 3,865 participants and 338 bacterial samples.
The most common serotypes identified were 19F, 19A, 23F, 6B, and 14, with PCV7, PCV10, and PCV13 potentially covering a significant portion of these strains.
Only 1.8% of the isolates were penicillin-resistant, but nearly all were resistant to erythromycin, highlighting the high drug resistance of serotype 19A and suggesting that PCV13 would be more effective in preventing disease due to its coverage of this serotype.
