This study aims to assess the potential association of
MBL2 gene single nucleotide polymorphisms (SNPs) to
Chlamydia trachomatis infection. We analysed a selected sample of 492 DNA and serum specimens from Dutch Caucasian women. Women were categorized into four groups of infection status based on the results of DNA and antibody tests for
C. trachomatis: Ct-DNA+/IgG+, Ct-DNA+/IgG−, Ct-DNA−/IgG+, and Ct-DNA−/IgG−. We compared six
MBL2 SNPs (−619G > C (
H/
L), −290G > C (
Y/
X), −66C > T (
P/
Q), +154C > T (
A/
D), +161A > G (
A/
B), and +170A > G (
A/
C)) and their respective haplotypes in relation to these different subgroups. The −619C (
L) allele was less present within the Ct-DNA−/IgG+ group compared with the Ct-DNA−/IgG− group (OR = 0.49; 95% CI: 0.28–0.83), while the +170G (
C) allele was observed more in the Ct-DNA+/IgG+ group as compared with the Ct-DNA−/IgG− group (OR = 2.4; 95% CI: 1.1–5.4). The
HYA/
HYA haplotype was more often present in the Ct-DNA−/IgG− group compared with the Ct-DNA+/IgG+ group (OR = 0.37; 95% CI: 0.16–0.87). The +170G (
C) allele was associated with increased IgG production (
p = 0.048) in
C. trachomatis PCR-positive women. This study shows associations for MBL in immune reactions to
C. trachomatis. We showed clear associations between
MBL2 genotypes, haplotypes, and individuals’ stages of
C. trachomatis DNA and IgG positivity.
