Distribution of Chlamydia trachomatis ompA-genotypes over three decades in Port...
Lodhia, Zohra; Cordeiro, Dora; Correia, Cristina; João, Inês; Carreira, Teresa; Vieira, Luís; Nunes, Alexandra; Ferreira, Rita; Schäfer, SandraObjectives: Chlamydia trachomatis is classified into 15 major genotypes, A to L3, based on the diversity of ompA gene. Here, we evaluated and characterised the distribution and diversity of ompA-genotypes over 32 years (1990–2021) in Portugal. Methods: The collection of the Portuguese National Reference Laboratory for Sexually Transmitted Infections includes 5824 C. trachomatis-positive samples that were succes...
Surveying genetic markers of antibiotic resistance and genomic background in Ch...
Lodhia, Zohra; da Silva, Jorge Costa; Correia, Cristina; Cordeiro, Dora; João, Inês; Carreira, Teresa; Schäfer, Sandra; Aliyeva, Elzara; Portugal, ClaraObjectives: To survey genetic markers of potential antimicrobial resistance (AMR) to macrolides and fluoroquinolones among Chlamydia trachomatis–positive samples from the collection of the Portuguese National Reference Laboratory for Sexually Transmitted Infections (STIs), and explore a multiplex PCR approach coupled with NGS to provide complementary information regarding a strain’s genomic backbone. Methods: A...
Lymphogranuloma venereum (LGV) ompA-subvariants of the Portuguese collection of...
Lodhia, Zohra; Cordeiro, Dora; Correia, Cristina; João, Inês; Carreira, Teresa; Nunes, Alexandra; Ferreira, Rita; Schäfer, Sandra; Aliyeva, ElzaraBackground: Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by Chlamydia trachomatis ompA-genotypes L1–L3, with increasing numbers of detected cases across Europe. Here, we analysed diversity and temporal distribution of the LGV ompA-subvariants detected in Portugal between 2007 and 2023, in order to better understand the dissemination and diversification landscape of LGV strains.

Salmonellosis in Children at a Portuguese Hospital: A Retrospective Study
Mendes, Inês Filipa; Completo, Sara; Vieira de Carvalho, Rita; Jacinto, Sandra; Schäfer, Sandra; Correia, Paula; Brito, Maria João; Figueiredo, AntónioIntroduction: Salmonellosis represents a considerable health, social and economic burden in both high- and low-income countries. Recently, in Portugal, most cases of Salmonella infections have been reported in children under 15 years of age. The main aim of this study was to characterize, from an epidemiological, microbiological, and clinical perspective, cases of Salmonella isolation among children.Material an...
