Koide K, Uchitani Y, Yamaguchi T, Otsuka N, Goto M, Kenri T, Kamachi K. Whole-genome comparison of two same-genotype macrolide-resistant Bordetella pertussis isolates collected in Japan. PLoS One 2024; 19:e0298147. [PMID: 38359004 PMCID: PMC10868825 DOI: 10.1371/journal.pone.0298147] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 01/19/2024] [Indexed: 02/17/2024] Open
Abstract
The emergence of macrolide-resistant Bordetella pertussis (MRBP) is a significant problem because it reduces treatment options for pertussis and exacerbates the severity and spread of the disease. MRBP has been widely prevalent in mainland China since the 2010s and has been sporadically detected in other Asian countries. In Japan, two MRBP clinical strains were first isolated in Tokyo and Osaka between June and July 2018. The isolates BP616 in Osaka and BP625 in Tokyo harbored the same virulence-associated allelic genes (including ptxP1, ptxA1, prn1, fim3A, and fhaB3) and MT195 genotype and exhibited similar antimicrobial susceptibility profiles. However, despite their simultaneous occurrence, a distinguishable epidemiological link between these isolates could not be established. To gain further insight into the genetic relationship between these isolates in this study, we performed whole-genome analyses. Phylogenetic analysis based on genome-wide single-nucleotide polymorphisms revealed that the isolates belonged to one of the three clades of Chinese MRBP isolates, but there were 11 single-nucleotide polymorphism differences between BP616 and BP625. Genome structure analysis revealed two large inversions (202 and 523 kbp) and one small transposition (3.8 kbp) between the genomes. These findings indicate that the two Japanese MRBP isolates are closely related to Chinese MRBP isolates but are genomically distinct, suggesting that they were introduced into Japan from mainland China through different transmission routes.

Emergence and spread of MT28 ptxP3 allele macrolide-resistant Bordetella pertussis from 2021 to 2022 in China. Int J Infect Dis 2023; 128:205-211. [PMID: 36632892 DOI: 10.1016/j.ijid.2023.01.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 12/05/2022] [Accepted: 01/03/2023] [Indexed: 01/11/2023] Open
Abstract
OBJECTIVES To reveal the clinical and molecular characteristics of Bordetella pertussis (BP) prevalent in Shanghai, China. METHODS A total of 9430 children with suspected pertussis from 2021 to 2022 were included, and nasopharyngeal swab samples were collected for polymerase chain reaction detection, culture, antimicrobial susceptibility testing, and 23S rRNA gene A2047G detection. BP strains were typed using multilocus variable-number tandem-repeat analysis and virulence genotyping. RESULTS Of 9430 cases, 5.1% and 1.6% were confirmed by polymerase chain reaction and culture, respectively. Infants (aged <1 year) accounted for 24.7% and presented much more severe symptoms than noninfants. Pertussis was most frequently detected in infants aged 0-6 months (11.3∼14.0%) and children aged >6-10 years (10.8∼21.7%). Macrolide-resistant BP (MRBP) accounted for 89.3%, and all carried the A2047G mutation. There were six multilocus variable-number tandem-repeat analysis types (MTs), including MT28 (62.0%), MT195 (20%), MT27 (10.0%), MT104 (4.7%), MT55 (2.7%), and MT32 (0.7%). BP strains with pertussis toxin (ptx)P3/(pertactin) prn2/ptxC2/ptxA1/(fimbrial proteins) fim2-1/fim3-1, including MT27, MT28, and MT32, accounted for 72.7%, among which MT27 and MT32 were macrolide-sensitive BP, whereas most (94.6∼100%) of MT28 were MRBP. Strains harboring ptxP1/prn1/ptxC1/ptxA1/fim2-1/fim3-1, including MT55, MT104, and MT195, belonged to macrolide-sensitive BP. CONCLUSION The emergence and spread of MT28 ptxP3-MRBP was first reported in China, highlighting the importance of continuous surveillance of ptxP3-MRBP to prevent its potential circulation.

Abstract
Resurgence and spread of macrolide-resistant Bordetella pertussis (MRBP) threaten global public health. We collected 283 B. pertussis isolates during 2016-2022 in Shanghai, China, and conducted 23S rRNA gene A2047G mutation detection, multilocus variable-number tandem-repeat analysis, and virulence genotyping analysis. We performed whole-genome sequencing on representative strains. We detected pertussis primarily in infants (0-1 years of age) before 2020 and older children (>5-10 years of age) after 2020. The major genotypes were ptxP1/prn1/fhaB3/ptxA1/ptxC1/fim2-1/fim3-1 (48.7%) and ptxP3/prn2/fhaB1/ptxA1/ptxC2/fim2-1/fim3-1 (47.7%). MRBP increased remarkably from 2016 (36.4%) to 2022 (97.2%). All MRBPs before 2020 harbored ptxP1, and 51.4% belonged to multilocus variable-number tandem-repeat analysis type (MT) 195, whereas ptxP3-MRBP increased from 0% before 2020 to 66.7% after 2020, and all belonged to MT28. MT28 ptxP3-MRBP emerged only after 2020 and replaced the resident MT195 ptxP1-MRBP, revealing that 2020 was a watershed in the transformation of MRBP.
