| Abstract |
This is the first study to investigate vertical transmission of Chlamydia trachomatis in Chongqing China. For this study, 300 cervical swab samples from pregnant women and 305 nasopharygeal swab samples from their babies (605 specimens) were collected for nest polymerase chain reaction (nPCR) of the ompl gene, which encodes the major outer membrane protein (MOMP) and typed C. trachomatis using Cleavase fragment-length polymorphism (CFLP) labeled with digoxin. From these samples, 11% (33/300) of pregnant women samples were successfully amplified. The vertical transmission rate of C. trachomatis from mother to baby was 24% (8/33). The vertical transmission rates were 66.7% (6/9) for mothers with vaginal delivery and 8.3% (2/24) for those with cesarean section. The incidence of premature membrane rupture among C. trachomatis-positive pregnant women was 30.3% (10/33), which was greater than among those who were C. trachomatis-negative (13.5%, 36/267; chi(2) = 4.2; p < 0.05). Four genotypes including type E (3 pairs), type F (2 pairs), type H (2 pairs), and type D (1 pair) were observed by CFLP assay labeled with digoxin and confirmed by DNA sequencing in the 16 C. trachomatis-positive samples from eight pregnant women and their eight infants. Each pair of matched maternal-infantile samples showed identical CFLP. This study showed the incidence of C. trachomatis infection in pregnant women, the vertical transmission rate for C. trachomatis, and the genotypes of C. trachomatis in Chongqing, China. The CFLP assay labeled at the 5' end of the forward primer with digoxin was first used successfully to genotype of C. trachomatis. As a promising method for C. trachomatis genotyping, CFLP had good sensitivity, reproducibility, and simplicity and no radioactive contamination. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 09 September 2023.
All research outputs
#7,453,350
of 22,786,087 outputs
Outputs from Current Microbiology
#487
of 2,409 outputs
Outputs of similar age
#48,955
of 169,644 outputs
Outputs of similar age from Current Microbiology
#5
of 12 outputs
Altmetric has tracked 22,786,087 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,409 research outputs from this source. They receive a mean Attention Score of 3.2. This one has gotten more attention than average, scoring higher than 53% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 169,644 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 19th percentile – i.e., 19% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 12 others from the same source and published within six weeks on either side of this one. This one is in the 8th percentile – i.e., 8% of its contemporaries scored the same or lower than it.
